What are the common collision phenomena in the production of rice processing plant?

Synopsis

As far as rice processing equipment is concerned, it is generally mainly composed of cleaning machine, stone removal machine, magnetic separator, ridge machine, rice milling machine, polishing machine, etc.

  As far as rice processing equipment is concerned, it is generally mainly composed of cleaning machine, stone removal machine, magnetic separator, ridge machine, rice milling machine, polishing machine, etc. In the process of rice milling, rice grains are mainly whitened. Whitening in room. Under normal circumstances, in the production of rice processing equipment, collisions inevitably occur during the whitening process of rice grains, and once the situation is serious, it is very likely to have an impact on subsequent production. So, what are the more common collision phenomena?

  1. The result of the collision between rice grains and rice grains:

  When rubbing off and whitening, the rice grains rub against each other under the great pressure of the rice processing equipment. Except for the loose skin layer peeled off by the whitening roller, the skin layer continues to be peeled off. When grinding and whitening, the pressure between rice grains is small and the impact force is large, which mainly removes the cortex that has been loosened by the grinding roller.

  2 Collision results between rice grains and whitening exterior walls:

  When rubbing off and whitening, the pressure between the rice grains and the outer wall is relatively large. Continue to peel off the skin layer by friction and rubbing, and discharge the peeled skin layer from the outer wall; when grinding and whitening, the pressure of the rice grains on the outer wall is small, and continue to go out through impact collision friction. The cortex has been loosened and drained from the outer wall. The rice grains bounce back from the outer wall, and the deformation of the outer wall is extremely small, and it appears as wear after a long time accumulation; the outer wall is of great quality compared with the rice grains, and it is fixed on the base of the rice milling machine of the rice processing equipment, so the outer wall is static. Yes, there is no change in speed.

  3. Collision results between rice grains and whitening rollers:

  Rice grains increase movement speed and increase energy. Because the angle of collision between the whitening rollers of rice grains is different, the collision parts are different, such as vertical collision or oblique collision with the whitening roller of rice processing equipment, collision with the circumferential surface of the whitening roller, collision with ribs or grooves, and the rice grains get The speed and direction are different, and the kinetic energy obtained is also different. The pressure is increased when rubbing off and whitening, and the speed is increased when grinding and whitening. These effects deform the rice grains, which are manifested by the excision, fracture, and peeling of the cortex of the rice grains, as well as an increase in the temperature of the rice. Therefore, the actual kinetic energy obtained when the rice grains leave the whitening roller is smaller than the kinetic energy that should be obtained, and the actual speed is also smaller than the expected speed. This reduced kinetic energy is consumed in grinding the cortex and breaking, peeling and raising the temperature of the rice layer. Compared with rice grains, the quality of the whitening roller is extremely large, and there is a power transmission, so the speed change is very small, and basically there is no change.

  In general, in the production of rice processing equipment, the collision phenomenon that occurs in the process of rice whitening usually mainly includes three situations: the collision between rice grains and rice grains, the collision between rice grains and the outer wall of the whitening room, and the collision between rice grains and whitening rollers. In order to avoid collisions If the equipment production is seriously affected, it is hoped that the relevant users must understand the above content.
