Rice milling plant machine丨automatic rice mill plant

Rice milling plant 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 of 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, the warranty for the integrated rice milling unit is 2years.

Brief introduction to the rice milling plant machine

The main function of our rice milling plant machine is to process brown rice into white rice. The machine includes not only a rice polisher, but also a de-stoner, a gravity grading sieve, and a vibrating sieve. The processed rice is white, beautiful and clean enough to be sold directly to supermarkets and snack processing plants. This combination of machines is the basic rice milling line, but we also have other combinations of machines. They are very different in terms of output and function.

We have different models of rice milling production lines from 15 to 60 tons. Customers can choose according to their needs. In addition, we also have rice and wheat threshing machines, which can first thresh the rice and then use the rice mill for deep processing.

The structure and technological process of the rice grinding machine

Rice grinding machine uses a 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 sieve further screens the broken rice.

Advantages of rice huller machine

  1. The rice milling machine is reasonable in structure, processing high-quality white rice.
  2. Compared with other types of rice milling machines for sale, the crushing part at the back of this machine can fully crush the rice husk that can be used to feed animals.
  3. 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.
  4. Rice hulling machine boasts a high purity rate, and the final rice is pretty white.
  5. There are no chaff and broken rice contained in the final rice.
  6. The gravity sieve works at high speed.
  7. low noise and no dust in the white rice.
  8. High capacity and low power consumption.

Working procedures of rice milling plant machine

  1. Put the rice into the feeding hopper(1).
  2. Elevator(2) conveys the rice into the rice destoner part (3) that removes the stone contained in the rice.
  3. Elevator(4) conveys the rice again and then rice drops into the huller part(5), removing the husk of rice.
  4. 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.
  5. And good rice will directly enter the rice mill part(8) to be polished.
  6. Polished rice enters the screening part(9) which vibrates violently to filter the broken rice and impurities again.
  7. Finally, you will get white rice from the outlet of the screening part.

How to disassemble the lower bearing of the hoist?

1. lose the fixing panel of the base bearing of the single (double) hoist(14, 15).

2. Remove the dust cover of bearing(1, 13) on both sides.

3. Loosen the flat plate fixing the bolt.

4. Use the iron to hold against the left shaft head and hit the right side.

5. Remove the hoist shaft.

The sequence of disassembling the lower bearing of the hoist.

15- 14-→2→1→12→13→5,8-9

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.

Solution:

  1. 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.
  3. 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).
  4. 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.

Successful cases of commercial rice mill machine

One: This commercial rice mill machine is suitable for rice processing factory, and we sold 5 sets to Nigeria last year. A good machine is always praised by its customer, and the following chatting record can vividly show it.  Most important, he wanted to buy more machines from us.

Two: Last week our UK customer ordered a 20 ton rice milling production line from us. The customer wanted to set up a small rice milling plant. He left his contact information by visiting our website. And then our sales manager communicated with the customer via WhatsApp. After understanding the customer’s needs, we recommended a 20 ton capacity rice milling machine to the customer. Finally the customer decided to buy this rice milling machine line. Below is the packing and shipping picture of the machine.
