Rice grading process is to classify the white rice into various grades according to the rice length or rice thickness; it can differentiate head rice and cracked rice, rice and rice-liked impurities. It is the later process in the rice processing.

White Rice Grader

This machine is mainly used to grade the white rice in rice mill. It utilize the size difference of rice granules to screen out the head rice, general rice, big broken rice, and small broken rice through continuous sifting of sieve plate with different pore size , therefore to achieve the goal of rice classification. It can be made in triple-layer sieve plates or four-layer sieve plates. It is the essential equipment to grade and classify the rice in the modern rice mill plant.

Feature

Compact in structure, stable in operation, good in technology, simple in maintenance.

Big output, attractive appearance.

Broken rice content is small in head rice.

Multiple layer screen plates are deployed to grade rice twice, which is to guarantee good effect.

Technical specification

Rotary Flat Rice Grader

This machine utilize planar rotary motion with large amplitude, rice granularity difference between head rice and broken rice, particular composite structure, and precise punched screens to separate superfine rice, common rice, big broken rice and small broken rice accurately from the white rice, improve the rice uniformity and create higher value of commodity. It is also can be used to grade other granule materials.

Feature:

Feeding mechanism of the machine adopts pressure adjustment and front suction system; pressure apparatus can make the materials evenly distributed on the screen surface to improve the screen effect; front suction device can effectively reduce rice temperature。

Adopts new-style compaction device to make screen-cleaning easy.

No material flushing, good classification effect, stable performance and good sealability.

Technical specification

Length Rice Grader

This machine utilizes the length difference between head rice and broken rice to separate both of them under the rotation of three perforated screen drums. It can make sure no broken rice in head rice, no head rice in broken rice. It is the ideal rice selection machine to be used in the later process of rice mill plant. The machine adopts multiple screen drum combined type to meet the demand of different technology process. It also can be used for the other grains.

Feature

Small land occupation and easy operation.  

It is the totally enclosed product with built-in type, the material flows smooth, there is no dust emission and the separation effect is stable.

Building block design, compact structure.

The screen drum is easy for the change, and it is punching forming by stainless or cold plate with different pore-size according to user need.

It can remove the round pebbles and barn grasses which are of the same diameter and specific gravity as white rice.   

Strong suitability and high separation efficiency.

Technical specification

Thickness Rice Grader

This machine is mainly to isolate the broken rice and immature granules according to different thickness under the rotation of octagonal screen drum round the horizontal axel. It removes the impurities and makes the rice classification. It favors the later processing and further improves the rice milling technology effect.  

Feature

Utilize chain transmission, which is reliable in structure and reduces the transmission loss.

Screen drum is with automatic cleaning device, which is easy in operation. It is with elongated hole and made by bended corrugated sheet steel. It is with excellent quality and durable. Both home-made and imported screen drum are available according to used need.

Impurities and dust can be removed by suction ventilation network.

Immature and broken rice can be eliminated by opening the bottom of the machine.

Stable running and small vibration.
