Author:admin Time:2022-01-19

Rice is one of the staple foods of people. It is a finished product that is processed by rice processing equipment (rice cleaning machine, stone removing machine, rice hulling machine, rice polisher, rice milling machine, rice grader, rice color sorting machine, packaging machine, etc). It is also one of people's favorite foods.

Rice Processing Process
The rice milling process in large commercial mills combines a number of operations that produce better quality and higher yield of white rice from paddy or rough rice.

The steps involved in rice processing are as follows:

When paddy enters a rice mill factory, it contains many foreign materials, such as, straw, weed seeds, soil, rocks and other inert materials. Therefore, when the rice is harvested and transferred to the rice processing plant, it needs to be cleaned in advance to ensure the normal operation of the machine and to obtain clean rice. The capacity of the rice pre-cleaner is usually 1.5 times the grinding capacity. In this step you need Rice Cleaner, Rice Rotary Vibrating Screen, Rice Destoner, etc.

Rice Hulling
The next step is remove the husk from paddy to get the brown rice. After the husk is removed, the product is called brown rice and is ready for the milling process. The husk is removed by friction as the paddy grains pass between two abrasive surfaces that move at different speeds. After dehusking, the husk is removed by suction and transported to a storage dump outside the mill. Husk accounts for 20% of the paddy weight and an efficient husker should remove 90% of the husk in a single pass. Paddy graders and paddy cleaners are used to separate brown rice. In this step, you need rice huller machine.

Paddy Separation
The paddy separator separates unhusked paddy rice from brown rice. The amount of paddy present depends on the efficiency of the husker and should not be more than 10%. Paddy separators work by making use of the differences in specific gravity, buoyancy, and size between paddy and brown rice. In this step, you need Paddy Separator, we have Double Paddy Separator and Gravity Paddy Separator.

Rice Milling
This stage removes the bran layer of rice turning brown rice into white rice. In this step you can get the white rice. In this step you can use Vertical Roller Rice Mill Machine, Vertical Emery Roller Rice Mill Machine, Horizontal Iron Roller Rice Mill Machine, Horizontal Emery Roller Rice Mill Machine. Rice mill process is a most important part for the complete rice mill plant.

Rice Polishing
The rice polisher machine is mainly used for rice on polishing process to further improve rice's smooth finish. It’s a key equipment for non-washing rice in rice processing plant.  The surface of rice is smoothened and it is given a shine by passing it through a series of rollers

Rice Grading 
It is a process in which broken rice is separated out and separating head rice into different lengths with Rice Length Grader, Rice Thickness Classifier. After polishing, white rice is separated into head rice, large and small broken rice, and “brewers” by an oscillating screen sifter. Head rice is normally classified as kernels that are 75−80% or more of a whole kernel. To attain a higher degree of precision for grading and separation a length or indent grader is used.

Rice Sorting
Discolored, yellow and immature rice is removed in this stage adding value to rice by rice color sorter.
