Products Description
Our Double Roll Rice Grinder is a practical and efficient grain processing machine built for rice milling work, perfect for turning brown rice into clean, bright white rice with minimal grain damage. It features a sturdy double-roller core structure, runs stably even in long-hour working, and is easy to operate and maintain-an ideal choice for rice processing workshops and small to medium grain processing plants of all scales.
Product Features
This machine features a horizontal, in-line arrangement of its double rollers, resulting in a compact structure and minimal space requirements.
01
The flexible feeding method and balanced output of the double rollers can meet the needs of various processing routes.
02
Utilizing strong negative pressure milling and multi-point adjustable air intake in the milling chamber, it achieves high output, high precision, and low rice temperature, resulting in processed rice with less bran powder and fewer broken grains.
03
The machine is equipped with an ammeter for simple and convenient operation.
04
Optional motor pulleys with various speeds are available to adapt to different rice varieties, allowing for optimal processing results.

Product Advantages
Low broken rice rate
Gentle double-roller milling keeps rice grains intact, boosting the whole rice output rate.
High efficiency
Dual rollers work in parallel, processing more rice in the same time than single-roller grinders.
Durable use
Wear-resistant roller materials and reinforced steel frame stand up to continuous daily operation.
Flexible adjustment
Roller clearance and milling pressure can be tuned for different rice varieties and whiteness needs.
Structural principles
The rice processing equipment consists of automatic feeding machines, miscellaneous grain cleaning machines, etc., which have the characteristics of automated operation, high rice yield, and no pollution. The working principle of the pneumatic double rubber roller huller is a type of huller that uses pneumatic control technology. Its working principle is to transmit air pressure to the inside of the machine through pneumatic equipment, generating a certain pressure to control the degree of hulling of the rubber roller.
The machine structure of the pneumatic double rubber roller huller is mainly composed of a frame, a pressure roller, a rubber roller, a scraper, and a pneumatic control device. The frame is the framework that supports the entire machine, the pressure roller and rubber roller are responsible for hulling operations, the scraper is used to remove residues generated during the hulling process, and the pneumatic control device controls the air pressure inside the machine. A layer of welded steel plate with a thickness of approximately 1.5-2.5 millimeters is placed between the pressure roller and the rubber roller to strengthen the structural strength of the machine.
Craft & Technology
This grinder adopts a negative pressure milling design to lower rice temperature during processing and reduce bran powder mixing. It is equipped with an independent bran separation system that quickly removes rice bran and dust, ensuring pure rice output. The precision feeding mechanism distributes rice evenly to the two rollers, avoiding uneven milling and improving product consistency. All key parts are precision-machined for smooth running and low energy consumption.
Application Fields
Widely used in small and medium rice processing plants, grain and oil processing workshops, and rural grain processing stations. It is suitable for milling various rice varieties like long-grain rice and round-grain rice, and can also be used for small-batch processing of rice for retail and catering industries.
Packaging & Shipping
The machine is wrapped with anti-scratch plastic film first, then fixed in a thick wooden case to prevent collision damage during transportation. We support sea, land and air shipping according to customer needs, and provide complete shipping documents for customs clearance.
