Описание

This Vertical Rice Mill With Sand Roller is designed for modern rice mills that need to process brown rice, parboiled rice, and white rice with high output and low broken rice. Unlike general-purpose milling equipment, this vertical sand roller rice mill is built around the physical characteristics of rice: its brittle grain structure, heat sensitivity, variable hardness, moisture content, and oil-rich bran layer. By combining a vertical milling chamber, a wear-resistant sand roller, adjustable pressure, and strong suction, this machine removes the rice bran layer gently and evenly, helping rice mills achieve clean, glossy white rice with a higher head rice yield. It is suitable for long-grain rice, short-grain rice, parboiled rice, and various local rice varieties, making it a practical choice for commercial rice milling plants.

Working Principle

The working principle of this vertical rice mill is based on controlled friction and gentle whitening. Brown rice or semi-milled rice enters the vertical whitening chamber from the top. Inside the chamber, the sand roller rotates at a controlled speed, while the rice grains move between the sand roller and the screen. The friction and cutting action gradually remove the bran layer from the rice surface. At the same time, a high-efficiency suction system pulls rice bran out of the chamber and removes the heat generated during milling. This is especially important for rice because rice grains are sensitive to heat and pressure; if the rice temperature rises too high, the grains can become brittle, develop cracks, and break more easily. By adjusting the roller speed, milling pressure, and discharge clearance, operators can control the degree of whitening for different rice types, such as hard parboiled rice, fragile long-grain rice, or softer short-grain rice. The result is uniform whiteness, smooth rice surface, and better grain integrity.

Функции

1. Vertical Sand Roller Milling Chamber for Gentle Rice Whitening
   The vertical structure allows rice grains to move downward naturally through the milling chamber. The sand roller removes the bran layer layer by layer instead of applying excessive force. This gentle action is particularly suitable for long-grain rice, which is more prone to breakage than short-grain rice.

2. Adjustable Roller Speed, Pressure, and Clearance for Different Rice Varieties
   Rice varieties differ in hardness, moisture content, and bran layer thickness. This machine allows operators to adjust milling parameters according to the actual rice being processed. For parboiled rice with a harder bran layer, higher pressure and suitable roller speed can be used. For softer or more fragile rice, lighter milling settings help protect grain shape.

3. High-Efficiency Suction System for Rice Bran and Heat Removal
   Rice bran is oily and can block the milling chamber if not removed quickly. The strong suction system continuously discharges rice bran and reduces heat inside the chamber. This keeps the rice temperature lower, reduces starch gelatinization on the grain surface, and helps maintain rice whiteness and gloss.

4. Wear-Resistant Sand Roller and Screen for Continuous Rice Production
   The sand roller and screen are made for long working hours and hard rice varieties. The durable roller maintains stable milling performance even when processing parboiled rice or high-volume white rice production, reducing frequent replacement and downtime.

Преимущества

1. Higher Head Rice Yield and Lower Broken Rice
   Because the machine uses gentle friction, adjustable pressure, and effective heat removal, it reduces stress on rice grains. This helps increase the whole rice rate and lower broken rice, which directly improves the commercial value of the final white rice.

2. Uniform Whiteness and Smooth Rice Surface
   The vertical sand roller design provides even bran removal around each rice grain. Rice is not over-milled in one area or under-milled in another. The result is consistent whiteness, fewer bran streaks, and a smoother surface that meets the requirements of premium rice markets.

3. High Capacity and Stable Continuous Operation
   The high-capacity design allows the machine to handle large volumes of rice in continuous rice mill plants. It is suitable for commercial rice milling lines where stable output, low interruption, and consistent rice quality are required.

4. Lower Rice Temperature and Less Over-Milling
   Rice quality is easily affected by excessive heat and repeated friction. The suction and cooling system, together with adjustable milling pressure, helps prevent over-milling. This protects rice grain integrity, reduces powder generation, and keeps the rice bran cleaner for collection.

Преимущества

1. More Profit from Every Ton of Paddy
   For rice mill owners, higher head rice yield and lower broken rice mean more sellable white rice from the same amount of paddy. This improves profit margins and reduces waste during rice processing.

2. One Machine for Multiple Rice Types
   The adjustable settings allow the same vertical rice mill to process long-grain rice, short-grain rice, parboiled rice, and different local rice varieties. This gives rice mills greater flexibility when buying paddy from different sources.

3. Lower Operating Cost and Maintenance
   The energy-efficient suction system, durable sand roller, and stable vertical structure help reduce power consumption per ton and maintenance frequency. Less downtime means higher daily output and better production planning.

4. Consistent Quality for Local and Export Markets
   Uniform whiteness, low broken rice, and clean rice surface help rice mills meet strict buyer standards. Whether for local wholesale or export markets, the machine supports consistent rice quality and stronger brand reputation.
