Small-Scale Rice Milling Mechanization Technology

I. Technical Content, Production Demand, and Current Application Status In rural areas of China, iron-roller rice mills are commonly used for rice processing. However, this process suffers from low efficiency, low milled rice yield, significant nutrient loss, and poor quality. With the improvement of living standards and the opening of the grain market, enhancing the quality of rice processing and increasing the commercial value of rice has become crucial. In recent years, the promotion of small-scale combined refined rice processing mechanization technology has effectively improved processing efficiency and quality, and has been widely welcomed by farmers. II. Typical Demonstration Application Results and Technical-Economic Indicators Small-scale combined refined rice processing equipment can significantly increase milled rice yield and improve rice quality. For example, using equipment with a daily output of 10 tons, operating 150 days per year, a 3% increase in milled rice yield is equivalent to the output of approximately 90 mu of additional farmland; upgrading rice quality by one grade increases the selling price by 0.2 yuan per kilogram, bringing significant economic benefits to farmers. III. Supporting Machinery and Types for Production Application Small-scale combined refined rice processing equipment is available in various models based on production capacity, allowing users to select the appropriate equipment according to their needs. In addition, a workshop of corresponding area and a matching power supply are required to ensure the normal operation of the equipment. IV. Key Technical Implementation Points and Precautions Operation must be carried out strictly in accordance with the instruction manual to ensure that the incoming paddy quality is suitable. Electrical safety should be observed, and dust removal and ventilation equipment should be installed to improve the working environment and protect the health of operators.
