What's the difference between a fresh-keeping cabinet and a refrigerator?

Many people may know that refrigerators and freezers work in exactly the same way, but they are not sure where the specific differences are. The following is the difference between the fresh-keeping cabinet and the refrigerated cabinet that I have sorted out for you. I hope you like it.

The difference between fresh-keeping cabinet and refrigerated cabinet

At present, according to the temperature classification, there are three kinds of freezers commonly used in the market:

1. refrigerator, the temperature is between 0 ~ 10℃;

2. Freezing room, the temperature is between-18 ~ 0℃;

3. Two-temperature refrigerator, the temperature is between 10 ~- 18℃.

Like fresh-keeping cabinets, the temperature of refrigerated cabinets is generally 0 ~ 10℃. People in the industry generally call it a refrigerator, and a fresh-keeping cabinet is generally called a fresh-keeping cabinet, but they are all the same.

The difference between fresh-keeping cabinet and refrigerator

Many people may know that refrigerators and freezers work in exactly the same way, but they are not sure where the specific differences are. Let's have a look.

Structurally, commercial freezers have different functions according to different uses. There are freezers, freezers and double temperature cabinets. Generally, the cabinets of supermarket freezer, convenience store freezer series and dessert shop cake and bread refrigerated display cabinet series are all single-temperature cabinets, which are either refrigerated or frozen. Only some stainless steel freezers used in kitchens have double temperature cabinets, which can be refrigerated and frozen. Single-temperature commercial freezers are generally integrated, and it is easier to smell if different foods are stored. In terms of appearance, the refrigerator is generally much larger than the refrigerator. Not very power-saving. The shape is relatively simple, the workmanship is average, and the big ones are generally used by some small people with more business. Generally used for commercial purposes, such as supermarkets, convenience stores, hotels and KTV. Therefore, the freezer is also called the commercial freezer. The refrigerator is generally smaller than the freezer. Save electricity (once every three days). Beautiful appearance and fine workmanship, generally suitable for home use.

The refrigerator is composed of a freezer and a fresh-keeping freezer, which can be refrigerated and frozen at different temperatures. The cold room is also a fresh-keeping room, which can store fresh fruits, vegetables, rice, meat and steamed bread. Garlic is not easy to germinate, and mung beans and red dates can be stored without insects. The freezer can store raw and cooked meat, ice cream and plastic bottled drinks bought from the wholesale market, and glass bottles that are not easy to store will be frozen; In this way, foods stored separately by refrigeration and freezing are not easy to cross-taste.

Difference between commercial fresh-keeping cabinet and domestic refrigerator

Refrigerators generally have two spaces, preservation and refrigeration. The fresh-keeping room is generally used to store fresh fruits and vegetables and some foods to be eaten in a short time, but it will not be stored for too long, and it will go bad if it is stored for too long. The effect of fresh-keeping cabinet is similar to it. What about the freezer? It is to store some food that has not been eaten for a long time, but it is not allowed to store fresh or liquid food.

This can actually be seen clearly from the outside. Refrigerators are generally smaller in size and more beautiful in appearance. Usually for domestic use. The volume of the fresh-keeping cabinet is much larger than that of the refrigerator. The shape is simple. Usually used in enterprises and factories. The changes of operating income and operating profit of fresh-keeping cabinets in recent three years are somewhat strange, which is unusual for ordinary enterprises. The fresh-keeping cabinet should be provided with moisture-proof and heat-insulation layer, so that the cold storage building has good sealing performance and moisture-proof and steam-proof performance.

1. The refrigerator consists of a freezer and a fresh-keeping freezer. It can be refrigerated or frozen, and the temperature of a room and a living room is different.

The cold room is also a fresh-keeping room, which can store fresh fruits, vegetables, rice, meat and steamed bread. Garlic is not easy to germinate, and mung beans and red dates can be stored without insects. The freezer can store raw and cooked meat, ice cream and plastic bottled drinks bought from the wholesale market, and glass bottles that are not easy to store will be frozen; Food stored separately by refrigeration and freezing in this way is not easy to taste.

2. Commercial fresh-keeping cabinets have different functions according to different uses. There are fresh-keeping cabinets, air curtain display cabinets and order cabinets.

Generally, supermarket fresh-keeping cabinets and convenience store fresh-keeping cabinets are single-temperature cabinets, which are either refrigerated or frozen. Only some stainless steel fresh-keeping cabinets used in kitchens have double temperature cabinets, which can be refrigerated and frozen. Single-temperature commercial fresh-keeping cabinets are generally integrated, and it is easier to taste if different foods are stored.

High quality characteristics of safety cabinet

1, the effective volume of supermarket fresh-keeping cabinets is large.

The technical parameters of high-quality fresh-keeping cabinets meet the requirements of international standards, and have been sampled and tested by the national quality and technical supervision institutions for many times over the years.

2. The temperature of the supermarket fresh-keeping cabinet is constant and the cooling speed is fast.

The working temperature of high-quality supermarket fresh-keeping cabinets is distinguished by the most suitable temperature for food storage or fresh-keeping. Refrigerators are suitable for plant foods, which can ensure that the juice contained in food is not lower than freezing point and remains fresh. The temperature of the freezer is-18 degrees Celsius, and the shelf life of the food stored at this temperature is as long as 1 month. The high-quality fresh-keeping cabinet not only ensures that the temperature of the fresh-keeping cabinet meets the requirements according to the standard, but also makes the refrigeration speed of the high-quality fresh-keeping cabinet faster by adopting the special-shaped evaporation tube and matching the unit with appropriate refrigeration capacity.

3. Commercial high-power compressor for supermarket fresh-keeping cabinet

High-quality fresh-keeping cabinets adopt commercial compressors. In addition to good starting performance and complete specifications of refrigeration capacity, commercial compressors can also be configured according to different requirements of products. Only commercial compressors can adapt to the characteristics of harsh use environment, frequent startup times and long running time of commercial fresh-keeping cabinets, and ensure product quality. Although the price of commercial compressors is higher than that of domestic compressors, the failure rate is less than two thousandths.

4. The fresh-keeping cabinets in supermarkets are all made of better materials.

All evaporation tubes of high-quality supermarket fresh-keeping cabinets are made of high-quality copper coils and processed into wide-sided abnormity. Stainless steel plate has smooth surface and uniform thickness. Adopting appropriate thickness not only ensures a long service life, but also makes the appearance of the fresh-keeping cabinet flat and firm. Copper pipe has better cooling transfer effect and corrosion resistance than aluminum pipe or composite pipe. High-quality copper coil has the advantages of high cleanliness in the pipe and few pipe joints, which can effectively prevent leakage or blockage in the refrigeration system. The circular tube is processed into a rectangle, which makes the contact between the evaporation tube and the cooling liner change from point contact to surface contact, thus expanding the transmission area and accelerating the cooling speed.

5. The heat preservation effect of the supermarket fresh-keeping cabinet is better.

The thermal insulation performance of insulation layer in the production process of fresh-keeping cabinet is not only an important quality index of fresh-keeping cabinet, but also an important factor in the use economy of fresh-keeping cabinet. In order to obtain good thermal insulation performance, it is necessary to select suitable raw materials and control the bulk density and cell diameter in the best range. Therefore, only by adjusting the temperature of materials, cooperating with special fixtures and mastering mature foaming technology can we produce fresh-keeping cabinets with good heat preservation effect.

6. The structure of the supermarket fresh-keeping cabinet is stronger.

The structural firmness of supermarket fresh-keeping cabinets is directly related to the service life of fresh-keeping cabinets. There is an integral angle steel frame between the shell and the inner container of the high-quality supermarket fresh-keeping cabinet, which is equivalent to placing steel bars in the cement precast slab, and the firmness is greatly increased. After all the door frames are welded and formed, the whole frame is foamed and formed at one time, which avoids the defect that the door is easy to fall off due to the unstable assembly of the door frames. The advantages of one-step forming of integral steel frame are obvious. Why don't other manufacturers use it? Due to the complexity of fixture requirements and difficulty in clamping, it is impossible for manufacturers to adopt this structure and technology because it is not for the benefit of consumers everywhere.
