The Common Types of Rice Huller

  • The common equipments of the Rice Huller(LIANGGONG) machine are three types: rubber roller glutinous rice huller machine, sand tray glutinous rice huller machine and centrifugal glutinous rice huller machine. The details of the operation, advantages and disadvantages of these three kinds of grain processing equipment are as follows.

    Rubber roller tamping huller machine: The main working part is a pair of horizontal rubber rollers or plastic rollers that are bonded or set on the cast iron cylinder. The axes of the two rollers are located in the same horizontal plane or slightly different in height, and are rotated at different rotational speeds. One roller is fixed in position and the other roller can be moved to adjust the rolling distance between the rollers. The difference between the line speeds of the two rolls is 2 to 3.2 m/s, and the sum of the line speeds should not exceed 30 m/s.

    Sand disc smashing huller machine: With the upper and lower round diamond discs, the upper disc is fixed, the lower disc is rotated, and the line speed is 20~25 m/s. The rice is shelled in the two sand discs due to the end-pressure tearing action. The advantage is that the brown rice has less bursting waist, the sand disc is more wear-resistant than the rubber roller, and the processing cost is low; the disadvantage is that the shelling rate is low and the broken rice is more. Compared with other grain processing equipment, its main working part is a ring-shaped emery disc which is bonded with cast iron disc. The upper and lower discs are fixed on the upper disc, and the lower disc rotates and can move up and down according to the grain size of rice. The size adjusts the gap (rolling distance) between the upper and lower sand discs.

    Centrifugal smashing huller machine: The main working part is a rotating shovel, and the outside is a fixed impact ring. The rice enters the work area and is accelerated by the slamming disk. It flies to the impact ring by means of centrifugal inertial force, and is shelled due to impact. The machine has the advantages of simple structure, convenient operation and management, low power consumption and low processing cost; only the broken rice is more, and the rice yield is low.
