Analyze the working principle of Rice Whitener(LIANGGONG)

After entering the pulverizing chamber through the flow regulating mechanism, the brown rice is sent to the sanding roller by the screw head and spirally advanced along the surface of the sanding roller. The sharp sand blade on the surface of the corundum sanding roller is rotated at a certain line speed to grind the brown rice cortex. The rice grains and the rice grains, the rice grains and the rice sieves are rubbed against each other to make them rough and white, and at the same time, the sputum powder is forced out of the rice grains by the air blowing action, and the sieve holes are discharged.

Rice whitener structure

The rice whitener machine is mainly composed of a feeding device, a whitening chamber, a discharging device, a transmission device, a spray system and the like.

The gap between the rice knife and the drum should be moderate, and the gap should not be smaller than the transverse diameter of the rice. Otherwise, the rice grains are easily broken; the gap cannot be larger than the longitudinal diameter of the rice grains, otherwise the rice grains are rough. Therefore, the rice knife gap should be selected between the longitudinal and transverse diameters of the rice grain; practice has shown that the rice knife gap should have a slight angle, that is, a little larger near the end of the exit knife, so that the milled rice is more complete.

The inlet and outlet knives should be well matched. When the imported knives are wide open and the exit knives are closed, the grain in the whitening room increases, the pressure increases, and the beige is white, but the broken rice is more; on the contrary, if the imported knives are closed, the exit knives are opened. The whitening room has less rice, the pressure is lower, and the milled rice is rougher.

Generally, the opening degree of the imported knife can be controlled to 1/2 of the entire opening degree, and the maximum is not more than 2/3. Some old operators remove the imported knives and let the imports be open. Generally, do not do this. Because all the grains are too much after opening, the pressure in the whitening chamber is too large, and the rotation resistance is large. If the outlet knife does not fit well at the moment, the belt will slip, and even the machine will be stuck or damaged. The exit knife should be flexibly mastered. In operation, the meter knife gap and the opening degree of the inlet knife can be fixed after being adjusted according to the regulations. As long as the operator operates the exit knife with his right hand, the left hand extends out of the palm and connects the rice at the lower end of the outlet to see if the rice is whole and the beige is white. If there are many broken rice, you can open a large exit knife; if the rice is rough, you can close the small exit knife. Take care of both, until the quality of the rice mill meets the requirements.

The Rice Whitener(LIANGGONG) machine is a kind of grain processing machinery for removing brown rice (cortex and germ) from brown rice and grinding it into white rice. The main working part is a whitening chamber formed by a rotating roller and a steel plate punched by a steel plate on the periphery. The brown rice is discharged from the rice outlet after removing the enamel layer in the whitening chamber, and the rice bran is discharged through the sieve hole of the rice sieve. The feeding amount of the feeding mechanism, the gap between the whitening chamber and the pressure can be adjusted, and the rice sieves of different hole shapes and sizes can be used to adapt to different needs. There is a pressure gate or gate at the outlet to control the size of the rice noodle and can be adjusted to obtain different grinding precision and flow.

1. The rice whitener is clogged and the output is reduced. The main reason is that the feed amount is too large, the discharge port pressure is too large or the discharge port is too small; the discharge port is blocked by the rice bran, which may be caused by the belt slippage, the roller wear or the rice knife wear; the raw material moisture is too high or the spiral head Wear and loose.

2, rice bran contains rice, too much broken rice. The main reason: the rice sieve is damaged or the joint seam is too large; the conveying head and the sanding roller joint are not flat, the surface of the sanding roller is not smooth; the rice machine outlet is not smooth; the rice knife is too thick, the distance between the roller and the rice knife is too small; the rotation speed is unstable.

3, the current sudden increase. The main reason is: the feed inlet is broken, the pressure gate is out of order, the rice sieve is broken, the rice sieve bracket is broken; the foreign matter entering the machine or the feed amount is too large; the outlet pressure door is out of order, the rice sieve is blocked, the rice is not smooth; Or the manifold is blocked; the power is out of phase.

4, the accuracy of the fuselage decreased, uneven white. The main reason: the rice knife is worn; the feed is too small or the discharge pressure is too small.

5, the body vibration is large, the bearing is hot. The main reason: the shaft or pulley is unbalanced; the anchor bolts are loose; the bearing is filled with too much oil or lack of oil; the lubricating oil is too dirty.

6, there is abnormal smell. The main reason: the roller is loose or broken; the foreign object is dropped inside the machine; the bearing and the seat are damaged; the belt is slipping; the nut is loose.

When the rotary Rice Whitener(LIANGGONG) equipment is idling, the force and rotation of the motor are transmitted to the main shaft through the V-belt, which drives the roller to run, and at the same time, through the flat belt, the worm gear and the gear transmission, the rice sieve is rotated at a low speed, and its rotation speed is ns. It is 2.4 to 5 laps per second.

When the rice whitener starts to work, it has become a flexible carrier for force transmission because the whitening chamber is filled with rice grains. At this time, the force energy and rotation of the motor are transmitted to the roller through the V-belt to complete the rice milling function, and at the same time, the rice sieve is accelerated by the flexible carrier for the rotary motion; however, the roller shaft passes through the flat tape, the worm gear and the The gear pair is transmitted to the rice screen for a fixed reduction ratio, at which time the rice screen cannot be accelerated to rotate.

When the rotary rice whitener machine is working, the motor outputs the force energy to the roller, and the roller rotates at a high speed to drive the rice grains to collide and tumbling in the whitening chamber, consuming most of the energy, and rubbing off the whitening by friction. At the same time, the rice grain in the whitening chamber is a flexible carrier for energy transmission, which drives the rice sieve and the roller to rotate in the same direction. The rotating rice screen has a part of force that can be transmitted by the gear transmission to the worm gear transmission to the flat belt transmission and then to the roller main shaft, that is, the torque of the rotating rice screen is fed back to the roller main shaft through the above route.

Therefore, in view of the particularity of the force transmission of the rotary screen rice whitener machine, the transmission system of the rotary rice sieve cannot be designed and calculated according to the force transmission route when no-loading, and the feedback torque of the rotating rice sieve must be used when the rice whitener machine is working.

The whitening movement of the Rice Whitener(LIANGGONG) is composed of the collision and rolling movement of the rice grains, which is the basic factor for the whitening of the rice whitener. The collision movement of the rice whitener is divided into three categories: the first type is the collision between the rice grain and the white roller to obtain the velocity and pressure; the second type is the velocity of the rice grains colliding with each other under a certain whitening pressure; the third type has The speed of the rice grains collides with other components in the white inner wall and the whitening chamber under a certain whitening pressure. The first type of collision is the basis of the whitening work.

Rice whitener machine wipes away the collision of whitening

Type 1 collision: The impact force generated by the collision of the rice grain and the iron roller rib on the forward surface acts on the joint of the cortex and endosperm of the rice grain. The rib exerts pressure on the rice grain, creating friction between the grain layer of the grain and the rib. The impact force and the friction force form a couple, the moment is the thickness of the skin layer, and the skin layer is broken and peeled off.

Type 2 collision: The average rubbing off between the rice grains and the speed at which the rice grains come into contact with each other produces impact and friction, and the formation of the force causes the cortex to continue to break and be peeled off.

Type 3 collision: The grain speed is low, mainly rubbing away the residual skin layer and discharging the peeled skin layer out of the sieve drum.

Rice whitener machine grinding and colliding

Type 1 collision: The impact of the rice grain and the sand blade collides with the centrifugal force, and the combination of the two causes the rice grain layer to be wedged by the sand blade. The applied force is decomposed into the cutting force and the cutting force to complete the effect of grinding the cortex. When the rice leaves the white roller, the grinding is terminated.

Type 2 Collision: Under the action of average grinding and whitening pressure, the rice grains collide with each other at a speed lower than the line speed of the sand roller to produce a "study" effect, removing the looser part of the skin layer that has been cut by the sand blade and removing it without loosening. Small cortex.

Type 3 Collision: The collision is the same but weaker than the Class. And the casted cortex is discharged.
