Structural Composition

1. Combination Cleaning Screen: This equipment features a fully enclosed body, effectively reducing dust generation. The motor can be adjusted as needed, with a processing capacity of 3 tons per hour, a power rating of 2000 watts, and a machine weight of 520 kilograms.

2. Pressure Roller Huller: Equipped with a built-in spring, it increases control pressure, allowing the rubber roller to apply greater force. Replacing the rubber roller is simple, and it uses a flat belt drive system that requires no oiling. High-quality bearings from reputable manufacturers ensure quiet operation and enhanced stability.

3. New Gravity Grain Rough Separator: This machine offers a faster separation speed than conventional models, maintains a lower rice temperature, and creates a dust-free working environment. Full-screen processing takes less than one minute, providing quick cleaning. It has an hourly output of 1.8 tons, is powered by a 1.1-kilowatt motor, and weighs 400 kilograms.

4. Double Air Jet Rice Mill: Featuring dual rice milling functions and an integrated air jet system, it effectively absorbs bran powder. The rice outlet is specially designed to be vertically adjustable. It uses a hexagonal rotating whitening chamber and an external fan that provides excellent bran suction.

5. White Rice Sorting Screen: As rice grains vibrate back and forth on the sorting screen, broken and whole grains naturally separate due to their different shapes.

6. Polishing Machine: Utilizing long polishing rollers, this machine reduces the rate of broken grains and enhances the clarity and transparency of rice grains.

7. Bucket Elevator: Capable of lifting 2 to 4 tons of rice per hour.
