The corncob used for rural life fire is now bought at a high price. What can this thing be used for?

Speaking of corncob, I believe most people know that it is corncob harvested by rural people when they grow corn. It is separated from the surface corn, and the remaining middle part is corncob. In the past, people in rural areas cooked corncob mainly by burning fire. Now the life of rural people has improved, most people burn gas, and some farmers who grow plants crush it and feed it to pigs and chickens. Corn cobs are leftovers for cooking in rural areas. Why do people want you to buy it now? Let me analyze it for you.

Use of corncob

Corn cob is made of corn cob after crushing and strict screening, which has the advantages of uniform structure, appropriate hardness, good toughness, strong water absorption and good wear resistance. Used for polishing, drying and wiping glass, buttons, electronic components, automobile parts and magnetic materials. The surface of the workpiece is bright, with high finish, and there is no water mark on the surface. It can also extract pentosan, xylose and other chemical raw materials to process furfural. In rural areas, it is used to feed pigs, cows and chickens and to grow fungi and mushrooms.

Used for cultivation of edible fungi.

Using corncob to cultivate edible fungi is not only environmentally friendly, but also cost-saving. The mouldy corncob is selected and fully mixed with sawdust, cottonseed hull, bran plant ash, phosphate fertilizer, urea and lime to form a cultivation material, which can be used to cultivate edible fungi such as Coprinus comatus.

Extract all kinds of chemicals

In addition, corncob can also extract a variety of chemical substances, such as ethanol, graphene, furfural, furfuryl alcohol and other substances, among which furfural is widely used, not only in the field of medicine, but also in pesticide production, plastics, synthetic fibers and so on.

Corn cob can be used as bacterial fertilizer.

Corn cob is the main raw material for edible fungi cultivation. Select dry corn cob without mildew and crush it into jade particles. This culture medium is suitable in thickness and good in air permeability, which is very beneficial to the growth of mycelium.

Corn cob can be used as plant charcoal.

Using corncob instead of wood as charcoal substitute, this kind of plant charcoal has no smoke, dust and waste residue in the process of non-ferrous smelting industry, and the effect is very obvious, and the price is cheaper than charcoal.

In a word, corncob has a wide range of uses. Because of the great demand in various fields, some people in rural areas used to buy corncob for cooking at a high price.

Someone went to the country and bought a lot of corn cobs. What is this for?

Corn cob is the "inner core" of corn cob after threshing. In the past, corncob was often used as firewood in rural areas. I remember when I was a child, I couldn't afford coal, so I used corncob as firewood.

Later, a chemical factory was built in a nearby town and a lot of corncobs were bought. Only then do we know that we are not burning corn cob, but burning money!

Having said so much, I haven't got to the point yet! Let's get down to business.

Before we talk about what corncob is for, let's know what corncob is for.

The seemingly insignificant corncob is very useful. It is not only an industrial raw material, but also a raw material for agriculture and animal husbandry. Therefore, corncob is very precious!

Industrially, corncob can ~ ~

1, which can be used to extract heavy metals from wastewater, and its extract can be used as "isolation agent" to prevent hot steel sheets from sticking together;

2. It can be used as filler of glue or paste, and can be used to make cardboard, cement board, cement brick, etc.

3. It can be used to make packaging materials, and can also be used as "igniter" in gunpowder technology;

4. It can be used as an auxiliary agent for rubber. If it is added in tire manufacturing, it can greatly increase the friction between tire and ground, thus indirectly increasing the traction of motor vehicles and prolonging the service life of tires;

5. Its extract can be used in dry cleaning industry, and the fur treated with its extract is clean and beautiful;

6. It can be used to produce furfural and xylitol. We bought corncob near the town to produce this product.

7. It can be used for polishing, drying and drying glass, buttons, electronic components, automobile parts and magnetic materials.

8, can extract cellulose, hemicellulose, lignin, etc. , commonly used in papermaking, biological sugar and other industries.

These are the industrial uses of corncob. Let's talk about its use in agriculture and animal husbandry.

In agriculture and animal husbandry, you can ~ ~

1, which can be used as feed premix, and can also be used to produce methionine, lysine, lysine protein powder, betaine, various enzyme preparations, fungicides, vitamins, phospholipids, phytase, flavoring agents, equinurokinase, apramycin, choline chloride, etc.

2. After the corncob is crushed, it can be used as a cultivation base for cultivating edible fungi.

These are the main uses of corncob in agriculture and animal husbandry.

After talking about the use of corncob, let's talk about what the rural areas buy a lot of corncob for.

As far as I know, most of the corn cobs bought in large quantities are sold to chemical plants. Because corncob is the basic raw material of some chemical industries, it needs to be purchased in large quantities. Of course, some large edible fungi factories also need to buy corncob, but the quantity purchased by edible fungi factories is limited and seasonal.

To sum up, corncob is widely used in industrial and agricultural production. Except for some used to produce edible fungi, a large number of purchased corncobs were sold to chemical plants.

My uncle earned 0.2 million/200 thousand a year by buying corncob. He said: the countryside is full of treasures, but we just can't find them! A small corncob can also create great wealth value.

Speaking of corncob, I think everyone is familiar with it. If you live in the north, you have seen much more corncobs than you have eaten, and you will see a lot in the south. When I was a child, I remember my grandmother used it as firewood, and the fire was very big.

Let me explain to you what corncob is first: it refers to the cob formed after corn falls off. This is what you call corncob. According to the composition of corn, there are red corn cob and white jade rice cob.

With the passage of time, we gradually found that corncob is actually very useful and can be applied to all aspects. At this time, we gradually discovered business opportunities, and my uncle was one of them. There is no shortage of business opportunities in this world, what is lacking is the eyes to find business opportunities. I think this sentence is very good to use here.

What is the function of corncob? Why would anyone pay a high price for it? The corncob itself has the functions of strong water absorption, good wear resistance and good toughness. It is precisely because of these functions that they can be used in all aspects and contain a lot of elements. These elements can be processed into different raw materials.

First, corncob can be cultivated as edible fungi.

Anyone who has planted mushrooms knows that the raw materials of mushrooms need a lot of sawdust, plus other materials, and put some corncobs at the same time, you can cultivate a mushroom bag. If a mushroom bag grows well, it can grow a lot of mushrooms, so it can be used again in the next year.

Because corncob contains a lot of elements and high sugar, which are exactly what mushrooms need to grow,

Therefore, many kinds of mushroom people will add a lot of broken corncob to this mushroom bag to facilitate its rapid growth and make healthy food.

Second, maltose and xylitol can be made.

Corn cob contains 54.5% sugar and 2.2% coarse protein. After processing and refining, we can mention the maltose we need. According to statistics, 100 kg of corncob can make 50 kg of maltose.

Maltose is generally sweet and delicious, and it is also deeply loved by everyone. At the same time, it has the functions of expelling toxin, caring skin, invigorating spleen and qi, moistening lung and relieving cough, so the whole consumer market is relatively large, and more and more people buy corncob because it can produce a lot of maltose.

Another commodity that we often eat is xylitol, which can also be processed and refined from corncob. The principle is still the same, because corncob contains a lot of sugar.

Everyone knows that xylitol can whiten teeth and clean mouth, but besides these corncobs, xylitol can also be used for diabetics because it is their savior. It can be used as nutritional supplement and adjuvant therapy. Basically, what is sold outside is extracted from corncob.

Third, you can make citric acid.

As mentioned above, in addition to rich elements, corncob also contains a lot of sugar, some crude proteins and minerals, and you can also extract citric acid (food additive) you need.

According to relevant data, about 10 ton of corncob can produce about10.5 ton of citric acid, which is equivalent to greatly saving other raw materials and making citric acid, which plays a protective role and increases waste utilization, which is quite a good thing in the United States.

Citric acid has a wide range of applications: it can be used as beverage, canned food, jam and candy, and it is also helpful to human body. It can enhance the normal metabolism in the body, so it is a better product.

Fourthly, it can be used as fertilizer.

After the recycled corncob is crushed evenly, it can be made into fertilizer, which can be used to irrigate the land and cultivate flowers and plants. It is also very fertile, because it contains a lot of chemical elements, so it is also very suitable for fertilizer.

As I told you above, it is also feasible to grow mushrooms, because mushrooms just need this fertilizer.

5. Chemical elements can be extracted.

In addition to the above, corn cob can extract maltose and xylitol, as well as ethanol and graphene. Corn cob is also possible, but the amount of extraction is not much, unlike maltose, 100 kg can extract half.

Because corn cob is mainly high in sugar content, it is possible to get such high maltose, but it will be less for ethanol and graphene, which is based on the above reasons.

Six, can be used as plant charcoal.

I believe everyone is familiar with this. Usually, if firewood is used at home, the burnt corncob is this kind of very environmentally friendly firewood, but direct burning and further processing of plant charcoal are similar to the artificial charcoal usually used for barbecue.

The same corncob can also be made into this kind of plant charcoal, but it needs further processing, and this kind of charcoal is much better than the so-called artificial charcoal, because it is basically smokeless and expensive.

Seven, can be used as rubber additives.

I believe that no one thought of this. Normal is an additive that can be made into rubber for tires. The advantage of this is to increase the friction between the tire and the ground, increase the traction of the tire, and achieve a balanced anti-skid effect. So most tires will have a little bit of this corncob. One is to increase friction, and the other is to increase the service life of the tire.

Eight, play the role of industrial water purification

General industrial clean water is very large and requires a lot of equipment. Unlike the small water purifier we make at home, it is this kind of large equipment, so they will put some corncob.

Because corncob has smooth surface, strong wear resistance, good water absorption and filtration, it can play a great role in this respect.

It is very good for general industrial water purification. After all, the cost is relatively low and the effect is not bad.

Nine, making feed yeast

After processing, it can be made into feed yeast, which can promote the digestion of gastrointestinal tract such as chickens and pigs and achieve a certain food intake.

At the same time, it is also a very good feed additive for manufacturers. After many times of processing, it can become the desired feed, and the production cost is relatively low.

Another is that it will produce rich nitrogen, phosphorus and potassium after chemical reaction with pig manure, which is the best fertilizer for crops, and can also be sold to growers and degraded at the same time. At present, this method has been tried by a large number of pig farms.

The above nine points are the functions of corncob, which can be said to be very useful. Although the corncob is not very eye-catching, the value behind it is great. If many people don't know these functions, they will use them as fire, which is also a pity.

Finally:

Everything has its applicable value behind it, especially in rural areas. Many things are turned from waste to treasure, so why do people buy in large quantities is because it is very useful. If there is a market, people will do it. Besides, if the market is so big, everyone will do it, and the natural price will be the highest.

As the saying goes, interlacing is like a mountain. If my uncle hadn't told me this, I still didn't know that corncob was so useful.

Corn can be said to be one of the popular foods. My favorite corn is sweet corn on the market now. It tastes fragrant and sweet, and it tastes good. Now it is not long before beginning of autumn, and it is also the harvest season for farmers. At this time, every household is busy breaking corn in the field. Corn is not only edible, but also a part of farmers' income. Some farmers will stay at home to feed chickens or crush them to feed pigs after harvesting corn; Some of them are directly broken into particles and sold for money. In my hometown, corn kernels will be used for food, while corn stalks and corn cobs will be used for cooking. Therefore, the overall role of corn is still relatively large.

In rural areas, most corncobs are used for cooking. However, people who have done relevant investigations have found different uses of corncob. People who specialize in recycling will go to every household to recycle corncob. They recycle corncobs, not to make a fire, but to grind them into powder and then mix them with other foods to feed livestock. This can save costs.

All friends who have planted mushrooms know that corncob is an essential material for growing mushrooms. So corncob is also a treasure for friends who grow mushrooms. Because the requirements of mushroom cultivation are higher than other crops. If the method is right, planting mushrooms once may earn tens of thousands or even hundreds of thousands of yuan. So the cost of growing mushrooms is relatively high, and corncob can just reduce the cost of growing mushrooms.

In addition, corncob can also be processed into xylitol, and the sugar extracted from corncob after technical treatment is not only xylitol, but also xylooligosaccharide and food-grade xylose. Xylitol is also the savior of diabetics, and can be used as sweetener, nutritional supplement and adjuvant therapy for diabetics. Commercial xylitol is also extracted from corn cob, bagasse and other crops.

Hello, developing agriculture through science and technology is helpful to you. What is the function of corncob? Why would anyone buy it? In fact, corncob has many functions. Here, I will share some functions of corncob with you to promote the scientific development of agriculture.

The most annoying thing when I was a child was harvesting corn. That is the most tiring time to harvest corn every year. Corn should be peeled and threshed in time when it is harvested, otherwise it will be easily moldy. Every year, you have to peel your hands to finish it. Corn cobs are usually dried at home for cooking and fire.

Corn cobs can be used to make fires and do many other things. Our most common corncob is used to grow edible fungi, which is the mushroom we often grow. Because the price of corncob is relatively low, and the sugar in corncob is very high, it is very suitable for planting mushrooms after treatment.

As feed: corncob is also a very good feed material. It looks ordinary, but it does contain a lot of nutrients. Corn cob contains a lot of sugar, crude protein, crude fat, a lot of plant fiber and a variety of trace elements. Just like this, using corncob as fertilizer is also a very good choice. Corn cob can be dried, crushed and processed, and then used as feed, which can be eaten by pigs, ducks and chickens.

Making fertilizer: Corn cob contains a variety of minerals and can be made into organic fertilizer through processing and fermentation. And this kind of organic fertilizer is very popular in the market at present. In the past, many farmers used corncob to make farm manure by themselves, and the principle was the same.

In addition to these common functions, corncob has other uses, such as extracting xylitol, xylooligosaccharide and food-grade xylose from corncob through industrial processing. As mentioned above, corncob is rich in sugar, and xylitol extracted from corncob is very suitable as a sweet additive for some special foods. Many professional corn cobs extract xylitol and export it overseas.

In addition, corncob can also extract a variety of chemical substances, such as ethanol, graphene, furfural, furfuryl alcohol and other substances, among which furfural is widely used, not only in the field of medicine, but also in pesticide production, plastics, synthetic fibers and so on.

At present, there are many enterprises that deeply process corncob. It can be said that the humble corncob plays a very important role, so it seems that most of the corncob purchases are for the deep processing of corncob. (3)

The autumn harvest has passed, and there are advertisements for corn cobs on the roadside in our countryside, which are purchased at a high price. What is this thing for? First, this kind of corncob is generally used to make a fire and cook in our countryside. As long as I can remember. Even if there is electricity, many people have corncob beside the fire cage at home, because many people know that cooking or cooking with fire is always better. As for the high-priced acquisition, it is definitely not used for ignition.

Secondly, with the development of science and technology, corncob is widely used, and it is no longer used for burning fire. People buy it at a high price, and some of it is processed into pig feed. By mechanical crushing, after some processing, there will be economic benefits.

Third, the corncob that is often used for fire in rural areas is directly burned, while the corncob burned in cities is not directly burned. Isn't there a mechanism for charcoal now? That kind of charcoal burns smokeless and tasteless, and it has strong firepower. People buy it at a high price to process it into charcoal, so they buy corncob, which is often treated as garbage.

Fourthly, in rural areas, we often see some straw houses like that. In fact, Pleurotus ostreatus is planted in it, and the materials that people grow Pleurotus ostreatus are also processed with this corncob. Growing Pleurotus ostreatus requires a large amount, so I buy it everywhere. In this way, corncob is more efficient as garbage. Moreover, in rural areas, we often pile corncob into a pile and then cover it with some farmyard manure. It becomes organic fertilizer after fermentation.

Seriously, when it comes to high-priced acquisitions, this is not high. Just a stumbling block in the countryside. It would be nice to sell a few dollars and add some vegetables, rice, oil and salt.

This is Green's personal experience in western Yunnan. Welcome everyone to discuss together.

Now the dried corn cob on the market is 50 cents a catty, which is what farmers call high-priced acquisition. There is a saying that "there is no redundant garbage, only resources are misplaced". There are really many good things in rural areas of our country that are not fully utilized, and corncob used by farmers to burn fires is one of them. Corn cobs should be used to exert greater value, rather than being reduced to ashes under the pot.

The utilization value of corn cob is 1. The crushed corncobs are used as padding for pens: now we have stricter requirements on the environmental protection of aquaculture, and seeking new environmental protection technologies is a new way out for aquaculture. Among them, the use of fermentation bed, padding culture technology is one of them. The carrier of fermentation bed is generally rice husk and sawdust, and our corn cob can also be used as the carrier of beneficial bacteria and fermentation strains after drying and crushing. The padding of my chicken coop is rice husk, then there are few corncobs, and then the padding of chicken is sold to people who want organic fertilizer.

2. As a carrier for making organic fertilizer: the fermentation padding in our enclosure can absorb feces and sewage, and then it can produce rich nitrogen, phosphorus and potassium after fermentation by the strains inside, which can be sold to growers and used as organic fertilizer. Then the manure treatment system of our large-scale farms is generally fermented by biogas digesters, and then dry and wet separation is carried out. Our biogas residue can be used as compost and fermented organic fertilizer together with crushed corncob. Corn cob fermented organic fertilizer can deodorize. This fertile soil can be sold to potted plants or provided to people who grow flowers and vegetables.

3. As the carrier of mushroom growth: Nowadays, we pay attention to healthy diet, and there are more and more fungi that are low in fat and promote digestion, but our mushroom production needs strain bags, and the carrier of strains is our common sawdust. However, due to the high sugar content of our corncob, it is more conducive to providing nutrition for the growth of mushrooms. So these mushroom producers are also willing to spend money on corncob.

4. Other use values: I mainly list these. Our corncob can also be used as filler for making compression boards and wooden doors. Then these substances are extracted by deep processing, and corncob can be made into xylitol, oligosaccharides, dietary fiber and so on.

Finally, in this information age, as long as you make good use of it, you can sell anything. But I want you to use it. I remember there were large rice fields in my hometown. Every year, after rice harvest, the remaining straws are piled in the rain, or some of them are taken home to make a fire. But then a college student sold all the rice and grass in that place online, as if it were used as padding or something. Therefore, "there is no shortage of business opportunities in this world. What is lacking is the eyes to find business opportunities."

Corn cob, known as "wooden stick" in my hometown, used to light a stove or cook, and few people came to the countryside to collect it! However, in recent years, many grain vendors have switched from grain to corn on the cob and made a lot of money! It is understood that at present, in my hometown, the price of corn cob collected by grain vendors is between 1.3~ 1.6 gross, while the price delivered to the purchasing point can be sold at 2. 1~2.3 gross, which is much better than earning 0. 1~0.3 gross per catty of grain!

So what's the use of corncob? The author asked many grain merchants, and they all said that corncob has the following uses!

First of all, it is used to make solid granular fuel to heat farmers in winter!

In recent years, with the increasing popularity of environmental protection, inferior coal combustion has been gradually eliminated in winter heating. How about replacing it now? In some places, the way of "replacing coal with gas" or "replacing coal with electricity" is adopted, and in some places, traditional boilers are reformed and biomass particles are used for combustion and heating. After all, the calorific value of this solid particulate fuel is also very high!

Secondly, it is used to process into animal feed!

Corn cob is rich in crude fiber, which can be used as feed for pigs, cattle, sheep and other livestock and poultry after crushing, which not only can reduce the feed cost of farmers, but also some people are willing to accept it!

Third, it is used to make fungus sticks!

In recent years, with people's love for mushrooms, many places have mushroom industries, and there are also enterprises specializing in the production of Pleurotus eryngii and other mushrooms near my hometown! For corncob, it can be used to cultivate mushrooms after being crushed into beans in a certain proportion!

Fourth, the recycling benefits of manure waste for farming!

In recent years, the "zero emission", harmless and resource treatment of aquaculture waste has become a new test for many farmers! For the treatment of aquaculture waste, some people are keen on biogas, while others are keen on making bio-fertilizer! No matter which kind of corncob is crushed, it can be used as an auxiliary material to treat aquaculture waste and realize "turning waste into treasure"!

We also buy from Xinxiang, Henan. If you simply sell corncob, it's probably 400 yuan/ton. If we install it ourselves, it's about 600 yuan/ton, and the price varies from place to place. In some places, the purchase price is only 350 yuan/ton, and the price gap is still relatively large. It is basically bought all over the country. If you don't know, I can also contact you. Let's talk about what they did when they bought corncob.

I won't introduce the chemical function of corncob. Some chemical plants extract some chemical products, and some even use it to extract xylitol and graphene. Of course, these are things that we don't often touch. We often come into contact with the following. There are not many corncobs really used for deep processing, but they are mainly used in agriculture.

1. Fermentation medium: Corn cob can be used to cultivate all kinds of mushrooms, which is the best choice for many mushroom growers, and the effect is particularly good after crushing. It is especially suitable for planting mushrooms after fermentation.

2. Add to feed: After boiling, remove most of the crude fiber, which can be added to pig feed, chicken feed, etc. It can promote gastrointestinal digestion and control the feed intake of breeding pigs. It is a very good feed additive.

3. Replace natural gas: Now some power plants use this kind of thing to cook pots, thus replacing some coal burning. Some power plants in southwest China have bought a lot.

4. paving the way: some farms use fermentation beds, and now many places use fermentation beds. Not only sawdust, but also this broken corn cob. Some are fermented by microorganisms, and some are not. But most fermentation beds have corncob.

In fact, we also need auxiliary materials in the brewing process, not only to add corncob, but also to add some sorghum shells. These are also essential in the process of brewing. The most commonly used methods are the above, and other methods are too far away from us. If you don't know where to buy it, I can also help you contact.

Corn cob, once used by rural people to burn fire to keep warm, is a good material for edible fungi. At present, the market is in short supply, so it is no longer wasted.

No one in my village can cook edible fungi. The first time I learned to use corncob as edible fungi was the year when my second sister got married.

My second sister's father-in-law is an edible fungus, mainly producing Pleurotus ostreatus. They belong to the canyon area, with little land and low corn yield. After the second sister got married, my second brother-in-law came to our village to collect corncob once, and later I learned that corncob can produce edible fungi.

At that time, all the corn cobs in our village were collected and many carts were pulled. I am particularly curious about how corncob grows Pleurotus ostreatus. It's incredible. Later, I went to my second brother-in-law's house to know that corncob was used to make mushroom buns.

The corncob was crushed and sterilized at high temperature, and the mother strain of Pleurotus ostreatus was put in a sterile environment. After a period of cultivation, Pleurotus ostreatus will grow.

In the past, people in rural areas used corncob for heating and cooking, but now most people use electricity, so the effect of corncob heating and cooking is not great, so every year people come to the countryside to buy corncob, which is generally used to produce edible fungi.

There is another use of corncob, which only rural people know. I remember when I was a child, my father burned a round corncob with fire to burn off the fluff on the surface, and then inserted a slender stick in the middle of the corncob to tickle it. At that time, the old people in rural areas were basically alone, and they scratched their backs with corncob.

Corn cob is generally used to produce edible fungi, and it is not expensive. In short, it is much better than burning, at least a few pence, and nothing is burned. Therefore, in rural areas, if someone buys corncob, farmers generally choose to sell it for money.
