Mini Rice Mill Machine Its Various Types And Uses

Mini rice mill machine has the function of a modern machinery. It provides a 5% higher yield of head rice, in addition to saving valuable rice bran. The Mini Rice Mill Machine with a capacity of 130 kg rice per hour meets the demands of the locals. This mill is electric driven and of automatic range.

Rice milling in the Mini Rice Mill Machine is done to remove the husk and the bran layers from paddy rice to produce whole white kernels. This rice is sufficiently milled, free of impurities and contains minimum broken seeds.

Rice Huller

A rice huller is a machine used to separate husk (chaff) of grains from the rice: a machine, Mini Rice Mill Machine with Destoner commonly used in Asia. The device uses steel rollers to remove the husk.

Rendering to their power usage, there are three kinds of hullers: mechanical hullers functioning on gasoline, electric rotary huller and hullers that can use numerous sources of power.

Modern Rice Mill Machinery

The commercial mills use a multi-stage milling process which gives high quality and output of rice. The whole process has several machines that perform different functions.

Pre-cleaning

After the rice has been harvested and dried, it must be separated from additional debris.

Husk Removal

The husk layer is detached from the paddy by Friction, and the procedure is called de-husking or de-hulling.

Types of husking machines

Steel Huller

It eradicates the husk and blanches the rice in one pass. Paddy is nourished between a rotating steel shaft and a cylindrical meshed screen. These machines take nearly 15-20 hp to run.

Under Runner Disc Sheller

This machine has two steel emery coating discs. The upper disc is stationary while the paddy flows from a centrally located hopper between the surfaces of the revolving lower disc and immobile upper disc. The struggle between the emery surfaces eliminates the husk leaving brown rice kernel.

Rubber Roller Huller

As the name denotes, there are two rubber rollers (same diameter), which function at different speeds to eradicate the husk. One roller has a fixed location while the other is modifiable to meet the anticipated clearance. The elastic roller rotates marginally slower than the immovable roller. The machine has an aspirator at the base to discrete the hulls from brown rice.

This method has efficiency as high as 85-90 % with minimum broken grains.

Paddy Separation

The production from the huller is a combination of paddy rice, brown rice, husk and wrecked paddy. The paddy separators then work by using the differences in specific gravity, buoyancy and size between brown paddy rice.

Polishing/whitening Process

The rice polishing process is classified as Abrasive (less pressure and suited for larger grains) and Friction (forced against each other, applying more pressure on the grain). We then get white rice irrespective of the process used in Mini Rice Milling.

Bagging

The fifth and final process is bagging, in which a suitable rice mill will produce 50-60% head rice (whole kernels), 5-10% large broken and 10-15% small broken kernels. This is packed and bagged, ready for transport.
