The Horizontal Rice Water Polisher represents a sophisticated solution for achieving premium quality polished rice through precision processing. Designed for integration into modern rice milling lines, this equipment transforms milled rice into glossy, clean grains with enhanced market appeal while maintaining nutritional value. The MPGV-80M model, a representative of this category, delivers an impressive processing capacity of 5 to 7 tons per hour, making it suitable for medium to large-scale rice processing facilities aiming to produce high-value rice products.
Utilizing a water mist polishing technique combined with gentle abrasive action, this horizontal polisher removes surface bran particles while creating a smooth, reflective surface on each grain. The result is rice with improved appearance, reduced breakage during cooking, and extended shelf life due to the removal of fat-rich bran layers that can cause rancidity.
The polisher features two horizontally aligned stainless steel rollers (1800mm length) that rotate in opposite directions, creating a gentle scrubbing action that removes remaining bran without excessive grain breakage. This dual-roller design ensures uniform polishing across the entire grain surface, achieving consistent quality throughout the batch.
An integrated water delivery system applies a fine mist (5-10ml per kg of rice) during the polishing process, which helps soften surface bran for easier removal while preventing excessive moisture absorption. The water flow is precisely controlled by a PLC system that adjusts based on rice variety and desired polish level.
The main drive system utilizes two high-efficiency motors (total 75 kW) with variable frequency control, allowing operators to adjust processing speed according to rice type and condition. The system's energy recovery features reduce overall power consumption, achieving a specific energy usage of less than 12 kWh per ton of processed rice.
A powerful suction system (15 kW blower) removes polished bran particles through a cyclone separator, ensuring efficient collection and preventing recontamination of polished rice. The closed-loop design minimizes dust emissions, improving workplace air quality and meeting environmental regulations.
Specialized rice mills producing high-quality varieties such as basmati, jasmine, and arborio rice utilize this polisher to achieve the glossy appearance and texture demanded by premium markets. The precise control over polishing intensity allows customization for different consumer preferences across regional markets.
In facilities producing parboiled rice, pre-cooked rice, and rice for sushi preparation, the water polisher ensures the consistent texture and appearance required for these specialized products. The controlled moisture application helps maintain optimal cooking characteristics.
For rice destined for international markets, the polisher plays a critical role in meeting strict quality standards for cleanliness and appearance. Its ability to produce uniformly polished rice enhances marketability and can command premium prices in competitive global markets.
The polishing process removes primarily the outer bran layer, which contains fiber and some fats, while preserving the starchy endosperm that constitutes the majority of the grain's nutritional content. By controlling polishing intensity, operators can balance appearance requirements with nutritional retention, typically removing 5-8% of the grain weight in premium polishing settings.
The polisher requires clean water with low mineral content (less than 100 ppm total dissolved solids) to prevent mineral deposits on rice grains and equipment surfaces. A water filtration system is included to treat incoming water, and the mist nozzles are designed for easy cleaning to prevent clogging.
The operator can adjust three key parameters: roller speed (variable between 300-500 rpm), water application rate, and processing time. Short-grain varieties typically require higher moisture levels and slower speeds, while long-grain rice benefits from lower moisture and faster processing to maintain grain length. Preset programs for common varieties simplify operation while allowing for custom settings.
