1. Product Overview

The rice polisher is a core supporting equipment in the refined rice processing production line. It is mainly used for the in-depth optimization of milled white rice. Adopting an integrated process of atomization humidification, flexible rubbing and negative pressure dust removal, it thoroughly removes residual bran powder, floating dust and impurities on the rice grain surface, smooths fine scratches on the rice surface, and upgrades ordinary white rice into high-quality refined rice with transparent color, full particles and better taste. Effectively solving the pain points of traditional processed rice such as dull color, easy bran adhesion, perishability and poor appearance, the equipment improves the commercial quality of rice while maximizing the integrity and nutritional components of rice grains and reducing processing loss.

This rice polisher is suitable for small and medium-sized rice mills, grain processing factories, agricultural cooperatives and grain and oil processing stores. It supports multiple processing requirements including new rice fine processing and old rice brightening renovation. With high production capacity, low broken rice rate and low energy consumption, it is a core processing equipment to upgrade rice grade and increase market premium.

2. Core Working Principle

The equipment adopts an advanced three-stage flexible polishing process, abandoning the traditional rigid grinding mode. Centering on "gentle shaping, precise dust removal and low-temperature fresh retention", it realizes low-damage processing throughout the whole process. The specific process is as follows:

1. Atomization Penetration and Humidification: Equipped with multi-point precision atomizing nozzles, the equipment converts clean water into nano-scale water mist, which evenly adheres to the surface of each rice grain, slightly softens the residual bran layer on the rice surface and activates the natural starch gloss layer of rice. The whole process adopts low-temperature processing with the rice temperature always controlled within 35℃, avoiding nutrient damage and rice grain cracking and deterioration caused by high temperature.

2. Flexible Rubbing and Polishing: The precise cooperation of high-wear-resistant polishing rollers and stainless steel sieve plates forms a bionic flexible rubbing structure, which gently polishes the rice grain surface, completely removes residual rice bran and fine impurities, smooths the concave and convex texture of the rice surface, makes the rice body smooth and delicate, and eliminates rice grain damage and fracture caused by rigid grinding.

3. Negative Pressure Winnowing and Dust Removal: Equipped with an independent negative pressure air suction system, the equipment synchronously absorbs and removes stripped bran powder, broken scraps and floating dust during the polishing process. Rice grains are kept in a suspended and loose state in the polishing chamber to avoid mutual extrusion and friction, which not only ensures uniform polishing effect, but also realizes complete separation of rice and bran, delivering finished rice free of impurities and dust.

3. Core Product Advantages

1. Low Broken Rice Rate & High Yield with Minimal Loss

By optimizing the structure and operating speed of the polishing chamber and adopting the flexible polishing process, the equipment avoids the drawbacks of violent grinding of traditional devices, greatly reduces the broken rice rate and significantly increases the whole rice rate. Meanwhile, it causes minimal weight loss of rice during processing, effectively improving the finished rice yield. It reduces raw material loss costs for processing plants and increases production profits, and is also applicable to the brightening renovation of aged white rice.

2. Superior Finished Product Appearance & High Market Premium

Rice processed by this equipment features uniform and transparent grains, bright and glossy color and smooth hand feel, with no bran powder, black spots or abrasive marks, completely solving the dull and gray appearance of ordinary rice. The appearance quality of the polished rice meets the standards of high-quality refined rice for supermarket sales. It has a softer taste, richer cooking flavor and longer shelf life, greatly enhancing the market competitiveness and pricing space of rice products.

3. Intelligent Temperature & Water Control for Stable Processing

Equipped with an automatic water control system, the equipment can automatically start and stop water supply according to the feeding volume, solving the problems of unbalanced humidity and uneven polishing caused by unstable feeding. The whole-process low-temperature processing mode protects protein, dietary fiber and other nutritional components of rice, retains the original flavor of rice, and avoids rice quality deterioration and yellowing caused by high-temperature processing.

4. Durable & Low-Maintenance with Low Operating Cost

All parts in direct contact with food are made of 304 stainless steel, and polishing rollers and sieve plates are made of special high-wear-resistant materials, which are corrosion-resistant, wear-resistant and not easy to deform, greatly extending the service life. The equipment adopts an open cleaning structure; the polishing chamber, air duct and bran storage area can be quickly disassembled and cleaned without dead corners, enabling simple and convenient daily maintenance. The whole machine features low energy consumption and low failure rate, ensuring low long-term operating costs.

5. Multi-functional & Widely Adaptable

The equipment supports multi-mode switching. The water adding mode is used for fine rice polishing and aged rice renovation, while the water-free mode can serve as a fine milling device for rice whitening and fine grinding. It can be matched with automatic rice milling production lines or operate independently, adapting to processing needs of different scales and scenarios.

4. Core Configuration Details

Precision Atomization System: Multi-point front and rear distributed atomizing nozzles produce fine and uniform water mist, ensuring consistent water absorption of rice grains and dead-angle-free polishing, avoiding polishing color difference caused by local unbalanced humidity.

High-efficiency Negative Pressure Dust Removal System: The high-power air suction device cleans bran powder and fine scraps in the polishing chamber in real time, keeps the chamber clean, prevents bran accumulation and rice adhesion, and ensures consistent product quality for each batch.

Adjustable Processing System: It supports multi-gear adjustment of polishing strength, feeding speed and rice output precision, and can be freely debugged according to different rice varieties (indica rice, japonica rice, fragrant rice) and diverse processing requirements.

Safety Protection Design: Equipped with overload protection and anti-jamming shutdown devices, the equipment operates stably without jamming or burnout failures. It is safe and easy to operate, enabling novice operators to get started quickly.

Thickened Body Structure: The whole machine is welded with thickened steel plates, featuring stable structure and strong shock resistance. It runs smoothly without jitter and noise, suitable for long-term continuous industrial operation.

5. Application Scenarios

Widely applicable to small and medium-sized grain processing factories, fine rice processing workshops, agricultural professional cooperatives, grain and oil trading companies, supermarket high-quality rice processing workshops, township rice milling stores and other scenarios. It meets various processing needs including new rice fine processing, aged rice brightening renovation, high-end gift box rice processing and high-quality rice pretreatment for canteens, adapting to large-scale batch production and small and medium-sized fine processing.

6. Product Value Summary

Unpolished traditional rice has residual bran powder on the surface, resulting in ordinary appearance, easy mildew and deterioration, rough taste and turbid rice soup after cooking, leading to low market price. With its refined and low-damage polishing technology, this rice polisher solves four core problems of rice including appearance, quality, taste and shelf life in one stop. Featuring low energy consumption, low loss and high production capacity, it helps processing plants upgrade rice product quality at low cost, create high-end premium rice products, rapidly improve market competitiveness and economic benefits, and serves as an essential equipment for quality improvement, efficiency increase and transformation and upgrading in the refined rice processing industry.
