Complete set of internal circulation grain drying equipment

At present, the mechanical drying capacity in China's agricultural production is not only low, but also there are few models suitable for rural production conditions, production scale and economic affordability. Most of the existing drying equipment in China is large and medium-sized, with an hourly processing capacity of 5 tons, 10 tons, or even more. Suitable for large and medium-sized grain depots and farms. The one-time investment is large and the operating cost is high, while farmers can only hope for opportunities and sigh. At present, there are some small grain drying equipment in China, but they are not suitable for the specific situation of rural areas in China. There are two reasons:

(1) Most small grain drying equipment uses oil as fuel, resulting in high operating cost. In the case of meagre grain output in China, it is unbearable for farmers.

(2) Although there are some small grain drying equipment using coal as fuel, their installed capacity generally exceeds the existing capacity in rural areas. Farmers need to increase capacity before using drying equipment, which increases the investment and operating costs of users.

Therefore, we think it is necessary to develop a small grain drying equipment that adapts to the existing production methods and conditions in rural areas. Therefore, the Complete Equipment Research Institute of China Agricultural University has developed 5HGN series complete equipment for grain drying, which matches the grain production scale of rural areas, farmers and small farms and is suitable for specialized households, village collectives and township agricultural service systems. Among them, the research and development of 5HGN-0.75 and 5HGN- 1.5 belong to the key projects at the ministerial level and the national key scientific and technological projects respectively, and have obtained national patents. At the same time, both models are walking.

This series of complete sets of equipment adopts the principle of circulating batch drying and has the following characteristics:

(1) has a compact structure, and the feeding, circulation and discharging share a hoist. And has the advantages of light weight, small volume and small occupied area. Among them, the walking drying equipment is easy to move and can be dried while collecting.

(2) The circulation speed is fast, the mixture is uniform, the dried grain is of good quality, the original color and nutritional components of the grain are maintained, the broken rice is less, and the waist burst rate is low.

(3) Automatic control to save labor. The operation is simple and easy to master.

(4) The installed capacity is small, which is suitable for the existing capacity level in rural areas.

(5) Put forward the indexes such as heat consumption, power consumption and reliability coefficient.

(6) The price is low, which is suitable for the economic bearing capacity of the vast rural areas. The operating cost is also lower than the cost of drying on the road.

5HGN series internal circulation grain drying equipment can be used for drying wheat, corn, rice and other crops, and can be widely used in rural areas, small farms and small and medium-sized feed mills.

Section 1 5 Working Parts of 5HGN Series Internal Circulation Grain Drying Complete Equipment

The working parts of 5HGN series complete grain drying equipment include: drying tower, hot blast stove and air supply system, feeding device, lifting device, grain discharging device, dust removal system and electrical control system. The walking type internal circulation drying equipment also comprises a walking device.

I. Drying tower

The drying tower consists of an inner cylinder and an outer cylinder. The upper part of the inner cylinder is conical and the lower part is cylindrical. The upper part of the outer cylinder is cylindrical and the lower part is conical. See 2- 1 for the schematic diagram. Both the inner cylinder and the outer cylinder are composed of several sieve plates. Sieve plate is made of thin steel plate according to certain rules, and there are holes in the steel plate. The conical shape of the upper part of the inner cylinder can ensure that the wet grain slides smoothly along its surface, so that the grain here will not stagnate and overheat during the circulating drying process, so that the exported grain is dried evenly and uniformly, and the quality of the dried grain is guaranteed. Therefore, its angle with the horizontal plane is greater than the angle of repose of wet grain (the angles of repose of rice, wheat and corn are 34-45, 23-38 and 30-40 respectively). The conical shape of the lower part of the outer cylinder can also ensure the smooth sliding of wet grains along its surface.

Brief Introduction of 5HGN- 1.5/2.5/3.5/5 Small Grain Drying Equipment

This complete set of equipment is designed on the basis of similar foreign products and combined with China's grain production.

A set of small walking internal circulation grain drying equipment has been successfully developed, which is suitable for drying corn.

Wheat, rice and other food crops, such as dry wheat and corn, have good quality, but dry rice has a low rate of cracking and broken rice.

Less rice and white color are the most prominent advantages of this machine.

The equipment consists of a feeding device, a drying tower, a coal-fired high-efficiency hot blast stove, a main fan, an induced draft fan and a dust collector.

Device, electric control system, walking device, etc.

It has the advantages of automatic temperature control, energy saving, no pollution, low operating cost and large precipitation range (one time can be reduced to

Low cost, simple operation and convenient movement.

1, dry wheat or corn per hour 1. 5-2.5-3.5/5T (0.6- 1.2-2.5t-3.5T for rice)

2. Save coal (calculated by the coal consumption per hour for drying wheat) by 20-25 kg, 30-35 kg, 40-45 kg and 50-60 kg.

3, electricity saving (calculated by the electricity consumption per hour of drying wheat) 8 degrees/hour.

4. The installed capacity is small10-13-18-27kw.

5. Covers an area of 20-60 square meters.

6. To realize automatic control, only two workers are needed to operate.

7. Low drying cost

The drying cost per kilogram of grain (calculated by wheat) is as follows:

How much is the coal fee per hour? 02t/h× 600 yuan /t = 12 yuan /h

Salary of personnel is 2× 10 yuan/hour = 20 yuan/hour.

The electricity bill is 5 pounds. /h×0？ 8 yuan/degree = 4 yuan/hour

The total hourly fee is 12+20+4=36 yuan.

36 yuan 1200 kg: 30 cents/kg?
