China's small polished rice processing mechanization technology

I. Technical content, production requirements and application status

1. Introduction of technology: At present, the processing technology of rice in rural rice producing areas in China mostly adopts iron roller type rice milling machine, which directly processes rice into rice by extrusion, pressing and smashing (called “rice out white”). This processing technology is backward, the rice yield and the whole rice rate are low, the nutrients in the rice are reduced, and the quality is poor. With the improvement of the living standards of urban and rural people, the liberalization of the grain market, the increase of the commodity rate and quality of rice, and its value-added are imperative. First, increase the income of farmers; second, to meet market demand; in recent years, popularize the popularization of small-scale combined rice processing mechanization technology in the majority of rice producing areas, that is, “rough out white” processing technology, which is welcomed by farmers.

The small combination of polished rice processing machinery is actually the concentration of the more advanced medium-sized rice processing plant. The equipment is generally used by elevators, cleaning screens, stone removers, glutinous rice machines, rice milling machines, polishing machines and dust removal ventilation. And other mechanical devices. The device has the advantages of compact structure, small floor space, high degree of mechanization, low investment, low energy consumption, convenient installation and debugging, and the like. The equipment processing rice, the rice yield is not less than 70% (compared with the iron roller rice mill, the rice yield can be increased by 3-5%), the grade of rice can be improved by 1-2 grades, and the nutrition of rice Less component loss.

The processing process is as follows: rice cleaning, de-sanding, rough separation of brown rice, layered grinding, selective classification and sealing packaging.

2. Production demand and application status. In the vast rural areas of rural areas to promote small-scale combined rice processing mechanization technology, the practice has proved that there are obvious economic and social benefits. At present, the first is the replacement of equipment for professional households engaged in rice processing, and the second is the investment hotspot of skilled farmers. One purchase is for 100 services. With the transformation of rural power grids and the construction of rural roads and the further liberalization of the grain market, Technology promotion provides favorable conditions and has broad prospects.

Second, the typical application of demonstration and technical and economic indicators

1. The expected economic effect of production applications. If the daily production of 10 tons of small combination of polished rice processing equipment, processing 150 days a year, according to the rice rate increased by 3%, equivalent to an increase of 65 tons of rice, calculated based on 500 kg of rice per mu, equivalent to the output of 90 acres of land, so Known as "invisible fertile land." The quality of processed rice is increased by one grade, the sales price per kilogram of rice is increased by 0.2 yuan, and the net value is 300,000 yuan, which is to increase the income of farmers by 300,000 yuan;

2. Analysis of typical application effects. A farmer purchases 10 tons of small-scale combined rice processing equipment for Nissan, the equipment purchase fee is 15,000 yuan, the new plant cost is 10,000 yuan, the annual processing rice is 1000 tons, the processing fee is 60 yuan per ton of rice, and the gross income is 60,000 yuan. After deducting electricity, accessories, equipment depreciation, and personnel wages of about 30,000 yuan, the investment can be recovered in one year, and the economic benefits of the purchasers are obvious. Some people say that "to be rich, rice processing is a way."

Third, the production equipment and types of supporting equipment

1. Classification of machine tools: Classification of wheat combination fine rice processing equipment: Generally, it is divided into daily production units such as 3 tons, 10 tons, 15 tons, 20 tons, 30 tons, etc. according to the productivity. Users can choose according to market demand according to local conditions.

2. Supporting facilities in production

1 Factory building: The factory building is mainly used for machine room, raw material warehouse, finished product warehouse and power distribution room. The user can determine the plant area according to the production scale, batch processing or sporadic processing. If it is a sporadic processing of the farmer's household, there is no need to build a batching library, and the finished product warehouse only needs to build a hangar, which is generally around 60M2.

2 Power supply: The supporting power of the equipment is three-phase alternating current. The building should be close to the transformer. If the distance from the transmission line is too far, a transformer matching the power of the processing unit should be re-installed.

3, the main technical parameters: productivity: 500-1000 kg / kWh (depending on the model)

Supporting power: 7.5 - 13.2 kW (depending on the model)

Rice yield: japonica >68%, japonica >70%

Broken rice rate: <3%

4, the main product type and scope of application: the main products currently promoted in rural areas, and the relatively large number of products are: NZJ-10/8.5 and NZJ-15/15. It is mainly used in remote mountainous areas, farms, township grain stations, rural enterprises and individual farmers.

5, the main manufacturer of small combined polished rice processing units

Anhui Nanling County Machinery Factory

Jiangsu Wujin Grain and Oil Machinery Factory

Hubei Anlu Grain and Oil Machinery Factory

Shandong Yutai Agricultural Machinery Repair Factory

Hunan Yinzhou Rice Mill Factory

Fourth, technical implementation points and precautions

1. Install and use in strict accordance with the instruction manual.

2. For the processing of rice for processing, the moisture content is too high to be processed; the rice of different varieties cannot be mixed and processed;

3, pay attention to electricity safety, to install leakage protection devices;

4. Dust removal and ventilation equipment should be installed in the processing plant to improve the working environment and maintain the health of the operators.
