Manual rice sheller

Types of Manual Rice Shellers

There are several types of manual rice sheller machines available in the market that helps in the extraction of rice efficiently. Some of them are as follows:

• Hand Operated Drum Sheller

  Hand-operated drum shellers are also known as pedal-operated rice shellers. They consist of a cylindrical drum that is rotated by pedals or hand cranks. The paddy rice is fed into the sheller, and as the drum rotates, it dehusks the rice by rubbing it against the stationary abrasive lining inside the sheller. These types of shellers require physical effort to operate, controlling the shelling process by adjusting the speed and feeding rate. Hand-operated drum shellers are suitable for small-scale rice processing.

• Rotary Hand Rice Sheller

  This type of manual rice sheller consists of a circular disc or plate with raised ridges. The paddy rice is placed on the plate, and the sheller is rotated by hand. As the rice moves over the ridged plate, it is dehusked through the abrasion and rubbing action. Rotary hand rice shellers are portable, lightweight, and easy to clean and maintain.

• Hand Operated Roller Sheller

  Hand-operated roller shellers consist of two horizontal rollers positioned closely together. The paddy rice is fed between the rollers, and it is dehusked through the compression and friction between the rollers. These shellers are compact and take less space. They are used in rural areas for small-scale rice processing.

• Lever-activated Slide Sheller

  They have a sliding mechanism that moves the paddy rice back and forth over a rough surfaced plate. The rough surface causes the paddy rice to dehusk. The manual lever is used to activate the sliding motion. They are simple and easy to use. They are also affordable for low-income individuals.

Specification and maintenance

Specifications of rice sheller machine may vary depending on the type and model. The following are key specifications and corresponding rice hullers' maintenance requirements to ensure their efficiency and durability.

• Material: Many manual rice huller machines are made of cast iron. Keep the paddy huller dry to prevent moisture from getting on it. For metallic hullers, avoid using corrosives on the paddy huller to avoid damaging and compromising its structural integrity. Use a neutral ph score to clean the rice huller.
• Capacity: The capacity of a manual rice huller is determined by the amount of rice it can process per hour. After use, clean the huller to maintain its capacity. Remove any rice particles or debris that may be stuck in the huller. Wipe it with a clean damp cloth and dry it up. Failure to clean the huller can lead to clogging and reduced processing efficiency.
• Adjustability: Manual rice hullers have adjustable features that allow users to control the level of rice milling or the amount of husk left on the rice. After use, check the adjustment components and make the necessary adjustments. Reset the huller to its default settings before the next use.
• Size: Depending on the type and model, a manual rice huller may have different sizes. Store the manual rice huller in a dry room that has a controlled environment. Extreme temperatures can cause warping, cracking or other damages. Extreme heat can also cause the huller to become brittle.
• Weight: Manual rice hullers are heavy despite being portable. After use, avoid lifting the huller by its parts. Instead, lift it from the base to prevent damages and breakages. When transporting the huller, place it securely in a vehicle to avoid movement that can cause damages.
