Description

Heat-dissipation rice hulling rubber roller

Technical Field

The utility model relates to an agricultural processing apparatus field specifically is a can dispel heat rice hulling rubber roll.

Background

The rice huller is a grain processing machine for hulling rice to obtain brown rice. It can remove the hull of the rice, reduce the waist burst and the damage of the epidermis of the rice grains and keep the integrity of the brown rice as much as possible. The main working parts of the rubber roller rice huller are a pair of horizontal rubber rollers or plastic rollers which are bonded on a cast iron cylinder or sleeved with a rubber layer. The axes of the two rollers are positioned in the same horizontal plane or have slight height difference and rotate oppositely at different rotating speeds, wherein the position of one roller is fixed, and the other roller can move, so that the rolling distance between the two rollers can be adjusted. The paddy is fed between two rollers uniformly over the whole length of the rubber roller by the flow plate (or by the feeding roller and the flow plate), and the constant-diameter rollers reversely rotate at different linear speeds, so that the paddy passing through the rollers is extruded and rubbed and torn. Due to the extrusion of the two rollers and the twisting and tearing action generated by the speed difference of the two rollers, most of the rice achieves the aim of hulling.

The rice huller rubber roll is used as a main accessory on the rice huller and is key equipment for rice hulling. The grain husking process generally goes through three basic steps: squeezing, tearing by rubbing and peeling, wherein tearing by rubbing is the key for shelling, and the size of tearing by rubbing depends on two important factors: firstly, the magnitude of the friction force; secondly, the relative action time of the reverse friction force on the grains is short. The surface temperature of the rubber roller subjected to friction force for a long time can be greatly increased, the rice hulling rubber roller is usually made of rubber, but the hardness of the rubber can be reduced along with the increase of the temperature, under the condition of lower hardness, the wear resistance degree of the rubber roller can be greatly reduced, and the working temperature of the rice hulling rubber roller is preferably below 50 ℃ (when the working temperature is above 60 ℃, the hardness of the rubber roller is reduced by 4-8 ℃).

The rice huller has the advantages that the rice huller rubber roll is adopted to hulle rice, the hulling rate is high, the surface of brown rice is smooth, broken rice is few, but the rubber roll is high in loss at higher temperature, the brown rice is more in waist explosion, and the production cost is higher.

In conclusion, the existing rice hulling rubber roll still has the following defects:

1. the long-time friction between the rubber roller and the paddy leads to overhigh temperature and reduced hardness, thereby leading to quicker loss of the rubber roller, needing frequent replacement and increasing the input cost of production and processing.

2. The excessively high surface temperature of the rubber roller can increase the popping rate of the brown rice, reduce the quality of the product and be not beneficial to the long-term sustainable development of enterprises.
