Rice huller machine consists of 9 parts and is a whole processing line to process the rice, removing the rice husk and other impurities during working. Its capacity is 600-700kg/h and you get rice with high quality. In recent years, we export this paddy miller to such countries as Thailand, Nigeria, Vietnam, Nigeria, etc, and those countries mainly market for it, thus our company has already built a long-time partnership with them. In addition, warranty for integrated rice milling unit is 2years.
The structure of rice huller machine
It is mainly composed of feed hopper, rice elevator, stone removing part, rice huller part, grader and sorter machine, electric cabinet and screening machine.

Main parts and related functions of rice huller
|2-Single hoist||Lifting rice to suction gravity stone remover from a dust belt|
|3-Suction gravity stone remover||Remove stone and straw from Rice|
|4-Automatic rice husking machine||Remove the husk from the rice and turn the rice into brown rice.|
|5-Twin hoist||It consists of two bucket belts. One is brown rice after the husk is broken by a lifting thresher, and the other is gravity sieve, which is cleaned by lifting and sucking specific gravity stone remover.|
|6-Gravitational sieves||Completely separate rice from brown rice.|
|7-Power Distribution Box||They are all contactor. Control the start of each motor.|

The structure and technological process
Rice milling machine uses single hoist to remove the ash, stone, and other impurities, and then conveys the raw material to the rice milling part and the gravity screen part through the double hoist, separating the crushed rice husk that will be blown out by fan and brown rice. The brown rice is processed into white rice by the rice miller, and the broken rice is further screened by the sieve.
Advantage of rice huller machine
- Rice milling machine is reasonable in structure, processing high-quality white rice.
- Compared with other types of rice milling machine for sale, the crushing part at the back of this machine can fully crush the rice husk that can be used to feed animals.
- High cleaning rate. It has a stone removing part, completely removing the little stone, grass, etc. In addition, the vibrating screen can filter the impurities again.
- Rice hulling machine boasts high purity rate, and the final rice is pretty white.
- There are no chaff and broken rice contained in the final rice,
- Gravity sieve works with high speed.
- low noise and no dust in the white rice
- High capacity and low power consumption
Working principle of rice huller machine
- Put the rice into feeding hopper(1).
- Elevator(2) conveys the rice into rice destoner part (3) that removes the stone contained in the rice.
- Elevator(4) conveys the rice again and then rice drops into the huller part(5), removing the husk of rice.
- Rice goes into the grader and sorter part(6), however, the rice with lightweight and bad quality will go into the rice huller part(5). Elevator(4) conveys these bad rice to the grader and sorter part again, which means bad quality rice will enter the rice huller part and elevator twice.
- And good rice will directly enter the rice mill part(8) to be polished
- Polished rice enters into the screening part(9) which vibrates violently to filter the broken rice and impurities again.
- Finally, you will get white rice from the outlet of the screening part.
How to disassemble lower bearing of hoist?
1.loose the fixing panel of the base bearing of the single (double) hoist(14, 15).
- Remove the dust cover of bearing(1, 13) on both sides.
- Loosen the flat plate fixing the bolt.
- Use the iron to hold against the left shaft head and hit the right side.
- Remove the hoist shaft.
The sequence of disassembling lower bearing of hoist
Note: When the single (double) hoist is in use, it is necessary to pay attention to the tightness of the bucket belt. If the hoist is easy to block or can not discharge rice, please check if the bucket belt, upper or lower base is loose. Then check whether the pulley fixing bolt is loose ( 5 ) and whether the iron plate at the exit of the upper seat of the hoist slides downward.
- Tighten the belt pulley on both sides of the hoist to tension the bucket belt.
2. Tighten the fixed bolt of belt pulley of upper and lower hoist.
- Open the cover of the upper part of the hoist and push the iron plate at the exit upwards, then lock it.(the distance that the iron plate pushes upwards should be based on the standard that the bucket belt does not hit the iron plate).
After the hoist is blocked, there is a gate on the left or right side of the lower seat of the hoist, which can be used to pull out the impurities in the hoist through the gate.
