The 20T/D small scale automatic rice mill machine is designed for all to medium-sized processing businesses, stands as a pivotal solution for entrepreneurs and agricultural cooperatives looking to transform paddy into high-grade white rice.
With a daily processing capacity of 20 tons, this compact unit integrates cleaning, husking, whitening, polishing, and grading into one streamlined production line, delivering finished white rice with high (head rice yield) and minimal broken rice percentage. As shown in the image, its modular steel frame layout ensures minimal floor space occupation while delivering industrial-level reliability, making it the ideal entry-level investment for emerging markets and rural processing hubs.
Small Rice Mill Machine Working Process
The 20T/D Mini Rice Mill Plant operates on a dry milling principle, processing paddy rice through a multi-stage mechanical workflow:
Paddy Cleaning → De-stoning → Husking → Paddy Separation → Whitening → Polishing → Grading → Finished Rice
The rice mill plant operates on a systematic dry-processing principle, utilizing a combination of pneumatic suction, gravity separation, and mechanical friction to remove impurities and husks while preserving the integrity of the rice kernel. The paddy enters at the top of the line and flows through a carefully choreographed series of machines connected by high-efficiency bucket elevators and air ducts. The detailed workflow involves the following key equipment:
Material Transport: Throughout the entire process, low-speed Bucket Elevators transport materials vertically between stages, minimizing grain breakage and ensuring a continuous, automated material flow. The entire system is monitored and regulated via a centralizedElectrical Control Panel, simplifying one-touch operations.
Stage 1: Multi-Stage Impurity Cleaning: The raw paddy first enters the combined cleaning sieve. Utilizing dual-layer vibrating screens and a powerful induced draft fan, it removes large stones, straw, dust, and lightweight chaff. This ensures only clean grains move forward, preventing premature wear on downstream equipment.
Stage 2: Paddy Hulling & Husking: The cleaned paddy is fed into the advanced Rubber Roller Huller (Gravity Hulling Machine). Here, the grains are squeezed between two counter-rotating rubber rollers at varying speeds, effectively peeling off the outer husk without damaging the endosperm.
Stage 3: Paddy-Grain Separation: The mixture of husked brown rice and unhulled paddy (about 80-90% husked) drops into the Gravity Paddy Separator. Utilizing the differences in specific gravity and friction coefficients, this vibrating screen accurately and gently separates the remaining paddy and recycles it back to the huller, ensuring a pure stream of brown rice enters the milling stage.
Stage 4: Rice Milling & Polishing: The brown rice proceeds to the Emery Roll Rice Mill. Through high-speed rotation and pneumatic pressure, the emery roller whittles away the bran layer, turning brown rice into white rice. Depending on the configuration shown in the picture, subsequent polishing and color sorting may further refine the surface gloss and remove broken grains.
Small Rice Mill Plant Features
Integrated Bucket Elevator System: Built with food-grade ABS buckets and heavy-duty belts, completely avoiding cross-contamination and material clogging.
Adjustable Rubber Roller Huller: Features a stepless speed-regulating system that allows precise control of the distance and differential speed between the rollers to suit different paddy varieties and moisture levels.
Dual-Air Channel Suction Cleaning: Combines vertical and horizontal air channels to thoroughly remove dust and lightweight impurities in a single pass.
Centralized Smart Control Panel: Equipped with clear indicator lights and overload protection switches, allowing one person to oversee the entire production flow.
Mini Rice Mill Plant Advantages
Ultra-Compact Footprint: Compared with traditional large-scale single machines, this combined plant reduces floor space usage by over 40%, making it suitable for warehouses or workshops with limited height and area.
Lower Broken Rice Rate: Thanks to the precise pneumatic control of the huller and the soft rubber contact surfaces, the breakage rate is controlled below 3-5%, significantly higher than old-fashioned steel-roller mills.
High Automation & Efficiency: Powered by a 20T/D capacity core, the plant can be run efficiently with only 2-3 workers, dramatically reducing labor bottlenecks.
Modular Assembly Design: All components are pre-assembled on a unified steel frame, enabling rapid installation, easy disassembly for maintenance, and seamless international container transportation.
Small Rice Mill Plant Benefits
1.Maximized Cost Savings: With high automation and reduced labor requirements, the plant significantly cuts down daily operational expenses, translating to a higher net profit margin per ton of processed rice.
Premium Market Rice Output: The thorough cleaning and precise milling process produce bright, white, and nearly impurity-free rice, allowing sellers to command premium prices in the local supermarket or wholesale markets.
Fast Return on Investment (ROI): With its moderate price point and stable 20-ton daily output, this equipment allows customers to recoup their initial investment within a remarkably short operational cycle (typically 6-8 months depending on local paddy costs).
Long-Term Operational Reliability: The equipment is engineered with energy-efficient motors that consume less electricity per ton, lowering the cost of production continuously over its 10+ year lifespan.
