Features

Consistent Rice Appearance

ANON rice whitener machines ensure a highly consistent whiteness and glossy over-finished rice. It is achieved by adjustable multi-stage pressure on the roller to adapt to different rice varieties. Additionally, the whitening duration can also be controlled by the export switch, which is easily accessible on the export of the rice whitener machine. Lastly, the uniformly distributed friction over the rice surface ensures every finished rice meets the premium quality standard for both the domestic and international markets.

High Head Rice Yield & Low Breakage Rate

ANON rice whitener machine is engineered to maintain a high head rice rate, improve grain integrity, and overall milling quality by minimizing grain breakage during the whitening process. The rice quality is ensured by optimizing the milling roller part and the temperature control system in the whitener machine.

Adjustable emery roller & screen clearance ensures the gap between the emery roller and sieve can be precisely adjusted to match different rice varieties and hardness. The optimized rotation speed control allows precise control of friction intensity in rice, reducing mechanical stress on softer rice varieties like jasmine rice, basmati rice, short-grain rice, sushi rice, and glutinous rice.

Our rice whitener machine adopts moisture balance protection during the temperature control process to minimize rice breakage. The built-in fan generates stable and continuous airflow, which helps dissipate heat and maintain optimal moisture levels, preventing excessive drying and reducing grain brittleness.

The VFD ensures that the machine uses only the energy needed, reduces electricity costs, and lowers operational expenses significantly.

ANON Rice Whitener Machine: Vertical & Horizontal

ANON manufactures 2 types of rice whitener machines: Vertical Rice Whitener and Horizontal Rice Whitener. The structural difference is the position of the milling roller, which lies vertically or horizontally. Vertical rice whitener, in general, results in lower rice breakage as the gravity even the rice distribution. While the rice is less evenly distributed in the horizontal rice whitener, the mechanical structure allows a very high processing capacity, making it ideal for a large factory. Below is a more detailed difference between these two models, find which one is better for your mill.

Vertical Rice Whitener Machine

Through the workings of gravity, rice travels from the top to the bottom of a machine. Due to its vertical design, the rice has a comparatively shorter time in the whitening chamber. The lighter milling process not only reduces rice breakage significantly, but also achieves higher-grade rice.

Best for:

Small and medium-sized rice mills that require compact equipment, flexible operation, and do not need extremely high output, while still demanding stable and high-quality whitening performance.

Horizontal Rice Whitener Machine

The large horizontal whitening chamber allows high-capacity and continuous processing. Stronger abrasive and friction pressure improve milling efficiency and ensure stable output under heavy-duty operation. 

Best for:

Large-scale or commercial rice mills that require high throughput and continuous, stable production, especially for integrated rice milling production lines.

ANON Rice Whitener Machine: Emery & Iron Roller

To meet different rice processing needs, ANON provides emery roller and iron roller rice whitener machines. Each kind serves a purpose for certain rice types and milling objectives. Refer below to select the most suitable solution for your rice milling needs.

Emery Roller Rice Whitener Machine

The abrasive surface of the emery roller is relatively rough, and it mainly uses abrasion instead of compression or friction polishing to peel off the outer bran layer.

Best for:

High-efficiency commercial rice mills that require fast whitening with high throughput capacity.

Suitable Rice Types:

Applicable for all the rice varieties with hard grain structure, having a high resistance to mechanical impact (such as:

Indica rice (long grain rice)

Parboiled rice

Other hard or medium-hard rice varieties

Iron Roller Rice Whitener Machine

The iron roller rice whitener mainly works through gentle friction between rice grains, resulting in a more uniform and gentle whitening process. This method helps maintain better grain integrity and a smoother rice surface.

Best for:

Production of high-quality rice with a high head rice yield and strict appearance requirements.

Suitable Rice Types:

Great for softer and much more fragile rice varieties like:

Japonica rice (short grain rice)

Jasmine rice

Basmati rice

Other premium aromatic rice types

FAQ

1. How to clean and maintain an ANON rice whitener machine?

To ensure your rice whitener machine is durable and maintains optimal performance, please thoroughly clean the rice grains and bran inside and outside the machine after each use, keeping it clean and dry. You should also regularly check the rice sieve for damage, the milling rollers for severe wear, and ensure all fasteners are tight. Remember to regularly add appropriate lubricating oil to rotating parts such as bearings, and frequently check the belt tension, as both excessively loose and excessively tight belts will directly affect the machine’s efficiency and lifespan.

2. How to solve the problem of high broken rice rate of the rice whitener machine?

You can address a high broken rice rate by considering both the rice itself and the machine’s settings. If the rice is too dry, the grains will become significantly more brittle. It’s recommended to humidify the rice before processing. Secondly, check if the pressure in the whitening chamber is too high; if the discharge pressure gate is set too tight, loosen it appropriately. Wear and tear on the milling rollers or improper rotation speed can also cause this; replace the rollers or adjust the speed promptly. Finally, ensure the feed is continuous and uniform; unstable feeding will also exacerbate rice breakage.

3. What to do if the rice whitener efficiency decreases?

When your rice whitener machine experiences problems such as decreased efficiency, reduced output, or extended processing time, the most likely cause is wear and tear on the milling rollers or screen, leading to reduced friction. You need to replace these core components promptly. Additionally, check if the belt is slipping, as this can cause insufficient milling roller speed; adjust the belt tension accordingly. Furthermore, reduced fan efficiency, preventing the timely removal of rice bran, will also severely affect the milling effect; it is recommended to clean the air ducts to ensure smooth airflow.

4. What is the difference between a rice whitener machine and a rice polisher?

Both a rice whitener and a rice polisher are key equipment in the rice milling production. The key difference lies in the purpose. A rice whitener machine is used to remove the outer bran layer from the brown rice through abrasion or friction and turning it into white rice. The rice polisher is used after the whitening process. The main purpose is to improve the apparence of the rice.

5. How does a rice whitener machine improve milling quality and output?

A rice whitener machine directly determines the final rice yield and controls the rice quality. ANON high-quality rice whitener ensures a consistent rice whiteness, a lower rice breakage, and a stable operation with less downtime can help optimize the overall productivity and profit of a rice milling plant.

6. What is the benefit of a rice whitener machine?

The key benefit is to improve the market value of the rice. 

Produce uniform white rice and improve its market value.

Support large-scale continuous rice whitening production and increase the overall efficiency and profitability.

7. Why do Chinese people eat white rice instead of brown rice?

In China, white rice has traditionally been more popular than brown rice due to various factors, including taste and texture. Although brown rice is becoming increasingly popular for its health benefits, white rice remains a staple food for many people due to its mild taste, soft texture, and easy digestion, especially when paired with delicious dishes.
