What Is Automatic Rice Husker

A rice huller or rice husker is an agricultural machine used to automate the process of removing the chaff (the outer husks) of grains of rice. Throughout history, there have been numerous techniques to hull rice. Traditionally, it would be pounded using some form of mortar and pestle. An early simple machine to do this is a rice pounder. Later even more efficient machinery was developed to hull and polish rice. These machines are most widely developed and used throughout Asia.
After harvesting rice, unhulled rice is harvested by rice combine harvesters. Combine harvesters will separate rice from its stem.
After packing the unhulled rice in grain bags, it will be hulled by a rice huller. A rice huller removes rice husks (chaffs) and other foreign substances. Brown rice will be proccessed by rice hullers.
Then, brown rice will be polished by polishing machines and the bran will be removed.

Working Mode of Automatic Rice Husker

An automatic rice husker consists of five main components: the feeding mechanism, hulling device, driving and tensioning mechanism, intelligent control system, and air separating device.

Intelligent Digital Vibration Feeding Mechanism:

The vibration feeding mechanism uses high-frequency (50 times/second) and low-amplitude (1.5–2.5 mm) vibrations to ensure that the thickness of the rice layer flowing into the long drip plate is uniform. This helps maintain a consistent material layer thickness across the entire length of the cots.

The long drip plate serves two functions:

1.Acceleration: It accelerates the material to the optimal speed before it enters the rubber roller and ensures that the material is thinned out, maintaining a single layer as it enters the roller.
2.Rectification: It aligns the rice in an orderly manner along the length of the cots, which improves the husking rate and reduces the rate of broken rice.

Rubber Roller:

Rubber rollers are consumable components that wear out over time. The wear rate can vary, and adjustments may be needed to account for differences in roller speed. The rigidity of the rubber roller's supporting structure is crucial for its mechanical properties and processing performance. The rice husker features a patented auxiliary supporting structure for the rubber rollers, which improves the reliability of the dual rubber rollers.

Innovative Drive and Tensioning Mechanism:

The automatic rice husker uses a synchronous belt drive structure, with the belt tensioned by a pulley spring. This setup ensures low noise, stable transmission ratios, and eliminates belt slippage. The multi-wedge belt drive system provides high transmission efficiency and operates at a low noise level (less than 80 dB).

Difference Between Rice Milling Machine and Automatic Rice Husker

Different Uses:
Automatic Rice Husker: The primary purpose of an automatic rice husker is to remove the husk from rice grains while minimizing damage to the rice and preserving the integrity of the brown rice. It focuses on peeling off the outer layer (husk) and keeping the brown rice as intact as possible. The automatic rice husker is designed for testing rice roughness and ensuring minimal damage during the hulling process.

Rice Milling Machine: In contrast, a rice milling machine is used to hull and whiten rice. It removes a significant portion of the husk and bran, and may also remove some of the rice embryo, resulting in polished rice. A small rice mill is ideal for sorting and inspecting yellow grains, sick grains, belly whites, and imperfect grains.

Functional Characteristics:

Automatic Rice Husker: This device is known for its aesthetically pleasing design, simple structure, and stable operation. It allows for adjustable sample sizes and is very convenient to operate. It has a high hulling rate of up to 99% in experiments, with minimal damage to brown rice and a low broken rice rate.

Rice Milling Machine: The rice milling machine is constructed with high-tech alloy materials, providing high hulling and whitening rates. It processes a large amount of rice quickly, with minimal broken rice. The machine is designed for efficient operation, with features to prevent dust leakage and ensure a smooth process. It is typically portable and has a capacity around 170 grams.

Structural Performance of the Automatic Rice Husker

The rice husking machine features a well-designed structure that ensures ease of operation. The air volume can be adjusted as needed, resulting in effective separation of brown rice husks.

The machine uses advanced international polyurethane rubber rollers, which operate at a relative differential speed to avoid damaging the brown rice during de-husking. These rubber rollers are lint-free, non-decolorizing, and durable. They can be adjusted for spacing to accommodate different types of rice grains. The machine achieves a husking rate of over 98% in a single pass with a low rate of brown rice breakage.

The husker allows for automatic and continuous feeding, with the ability to set the amount of paddy as required. By adjusting the air volume and fan speed, the machine ensures complete separation of brown rice from chaff.
