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 capacity 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. Moreover, upgrading rice quality by one grade increases the selling price by 0.2 yuan per kilogram, delivering substantial economic benefits to farmers. III. Supporting Machinery and Types for Production Application Small-scale combined refined rice processing equipment comes in various models based on different production capacities, allowing users to select the appropriate equipment according to their needs. Additionally, a suitable factory area and a matching power supply are required to ensure the normal operation of the equipment. IV. Key Technical Implementation Points and Precautions During operation, the equipment must be used strictly in accordance with the instruction manual. The quality of incoming paddy should be appropriate, electrical safety must be ensured, and dust removal and ventilation systems should be installed to improve the working environment and protect the health of operators.
