Abstract: Rice can be stored after drying, dehydrating, and removing impurities, and then husked with a rice mill when you need to eat it, which then becomes the rice we eat. Rice milling machine saves time and labor, the operation is also simple, then you know how the rice milling machine is rice? What is the working principle of the rice mill? What is the structure of the rice mill? Below with us to understand it.
The working principle of rice milling machine
Rice milling machine is mainly the use of mechanical equipment to produce mechanical force on the brown rice peeling milling white, brown rice from the feed hopper through the flow adjustment mechanism into the milling room, the spiral head to the sand roller and along the surface of the sand roller spiral forward, according to a certain line speed rotating diamond sand roller surface sharp sand blade, grinding brown rice skin, and make the rice grains and rice, rice and rice sieve friction and collision, so that the brown and milling white, and at the same time, by the At the same time, through the role of wind spray, forcing chaff powder out of the rice grain, discharged from the sieve hole.
The structure of the rice milling machine
Rice milling machine mainly consists of feeding device, milling room, discharge device, transmission device, wind spray system and other components.
1、Feeding device
The feeding device consists of three parts: feeding hopper, flow regulator and screw conveyor.
(1) Feed hopper
The main role of the feed hopper is to buffer, storage to ensure continuous normal production, there are two kinds of square and cylindrical, the general storage capacity of 30 ~ 40kg.
(2) Flow regulator
There are two main forms of rice milling machine flow regulating mechanism, one is the gate regulating mechanism, the use of the size of the gate opening mouth, adjusting the amount of feed flow, and the other by the full opening and closing of the gate and micro-adjustment of two parts of the regulating mechanism.
(3) screw conveyor
The main function is to push the material from the inlet into the whitening chamber.
2、White polishing room
The white room is the key working component of the rice milling machine, which is mainly composed of three parts: milling roller, rice sieve, rice knife or press sieve strip. Rice sieve mounted on the periphery of the roller, and the gap between the roller that is the white gap. When the roller rotates, the brown rice in the milling white room by mechanical force and get milling white, milling down the chaff through the rice sieve sieve holes out of the milling white room.
3、Discharge device
Discharge device is located in the end of the milling room, generally by the discharge port and export pressure regulator. Horizontal type rice milling machine discharging method has radial discharging and axial discharging two kinds. In the case of axial discharging, the discharging end of the milling roller must have a section of discharging rollers with oblique bars.
The role of the outlet pressure regulator is mainly to control and adjust the pressure of the outlet to change the size of the milling pressure. Therefore, the outlet pressure regulating mechanism must be responsive, flexible and able to open and close automatically, so as to play the role of automatic balance of pressure inside and outside the machine within a certain range of milling and whitening pressure.
4, transmission device
The transmission device of rice milling machine is basically composed of narrow V-belt, pulley and motor. The motor power is transmitted to the milling roller drive shaft by the narrow V-belt through the pulley, which drives the milling roller to rotate. Due to the different types of rice milling machine, the roller drive shaft can be placed horizontally and vertically, so the pulley is on one side of the drive shaft, also in the drive shaft above or below the V-belt specifications, models and number of roots should be selected according to the power size of the rice milling machine.
5, wind spray device
Wind spraying device is a unique device of wind spraying rice milling machine, which is mainly composed of fan, wind inlet set and wind spraying pipe.
