Chapter 4 The correct use of rice hulling rubber rollers
The shelling process of cereal grains generally goes through three basic steps: squeezing, rubbing and tearing, and peeling. Among them, rubbing and tearing are the key to peeling. The size of rubbing and tearing depends on two important factors: one is the friction, and the friction The size depends on the pressure between the two rollers; the second is the length of the relative action time of this reverse friction force on the grain, and the length of this action time depends on the relative speed of the two rollers, which is related to the difference in linear velocity. . It is not difficult to see that the pressure between the rollers and the linear speed difference are important process parameters for rice hulling. The correct selection of it not only directly affects the hulling rate, but also affects the consumption of rubber rollers.
