What is the Paddy Rice Separator Machine in The Rice Mill Plant?
Why Need to Use the Paddy Rice Separator in the Rice Mill Plant?
1. Promise rice mill machine working process
The raw material of the rice mill is generally brown rice, and the hulled material is a mixture of brown rice, paddy, and the mixture. The paddy rice separator machine is to separate the brown rice and other impurities in the mixture to provide raw materials for the rice mill. If it is not separated, it will greatly affect the process effect of grain separation.
2. Decrease the damage to the rubber roller
The rice grains separated by the rice separator are called back-hulled grains, and these back-hulled grains need to be returned to the huller machine for hulling. To improve the efficiency of the hulling machine, it is required that the brown rice content in the back-hulled grain should not exceed 10%.
If there is excess rice in the back-hulled grains, it will greatly reduce the productivity of the rice huller, increase the loss and energy consumption of the rubber rollers, and make brown rice hurt again.
Working Principle of Paddy Rice Separator
1. Technological characteristics of grain roughness mixture
(1) The brown rice size is different from the paddy size. Brown rice is hulled from paddy, so brown rice is smaller than paddy.
(2) There is a gap between the two tops of the rice husk and the brown rice, so the elasticity of the rice is greater than that of the brown rice.
(3)The density of paddy rice is small, and its bulk density and suspension speed are smaller than those of brown rice.
(4) The surface roughness of brown rice is smaller than paddy.
2. Basic working principle of paddy rice separator
To separate paddy and brown rice, it is necessary to fully understand the difference between paddy and brown rice to carry out effective separation. Paddy and brown rice are different in terms of particle size, density, suspension speed, and other technological characteristics.
With the help of the automatic classification produced by the grain-rough mixture during the movement, the brown rice with high density "sinks", and the rice with low density "floats", giving Separation of grain and roughness has created very favorable conditions, and the brown rice is separated by suitable equipment so that grain and roughness can be separated.
3. Requirements for paddy rice separator
The quality of the paddy rice separator not only affects the technological effect of the subsequent process, but also has a close relationship with the quality, and rice output rate.
If the brown rice contains too much paddy, it will affect the process effect of rice milling and reduce the quality of the rice; if the brown rice in the back-hulled grain is too much, it will affect the rice husker capacity and rubber roller and will damage the brown rice and increase the Broken rice and broken waist.
According to the requirements of the Ministry of Agriculture's industry standard: the net brown rice that has been separated by machines should not contain more than 40 grains of paddy per kilogram of brown rice, and the grain content of the ridged grain should not exceed 10%.
4. Paddy rice separator working ways
(1) Screening working way
The screening working way is based on the basic principle of screening. It takes advantage of the differences between brown rice and rice in particle size, relative density, volume mass, and friction factor, and is equipped with a suitable sieve hole size.
The grain-rough mixture is fully automatically classified on the moving sieve surface, and the brown rice with small strength, high relative density, and smooth surface sinks in the lower layer close to the sieve surface and leaks through the sieve holes.
The rice with a slightly larger particle size is blocked by the sieve surface and cannot be leaked so that the rice and brown rice can be separated.
(2) Density separation working ways
The density separation method is a method of separating grains on a rough working panel with reciprocating vibration by using the difference in relative density between brown rice and paddy and their automatic classification characteristics.
It is based on the basic principle of density sorting, and the premise is that the grain mixture is fully and automatically classified.
According to the difference in physical properties such as friction factor and density between brown rice and tamping, with the help of the rough working surface that is inclined and moves back and forth, The grain-rough mixture is automatically classified, and the denser brown rice sinks and is pushed upward from the upper part of the working face under the pushing action of the boss on the rough working surface, and the paddy is discharged from another outlet so that the grain-rough separation is achieved.
5. Paddy rice separator machine
According to the market demand and the principle of grain separation, the most commonly used grain separation equipment is the gravity paddy rice separator machine.
The gravity paddy rice separator machine uses a rough surface working member to separate grain by density separation method.
Efficiency, simple operation, and convenient management.
