The rubber roller husker is a grain processing machine that removes rice from the husk and makes brown rice. It can remove rice shells, reduce the explosion of rice grains and damage to the epidermis, and try to keep the brown rice intact. Mainly by the hopper feeding device, head device, chaff separation chamber, gear transmission, frame and other components.
It is very important to separate the chaff (commonly known as big sugar) in the mixture under the armpit after the ravine. Since the chaff has a large volume, a small proportion, and poor dispersion, if it is not separated, it will affect the technological effect of the subsequent production process. If a large amount of chaff is mixed during the grain separation process, it will inevitably hinder the fluidity of the grain mixture and reduce the separation effect.
Another example is that if you mix more husks in the back valley, it will also reduce production volume of rubber roller husker and increase power and plastic consumption. Therefore, setting the hull separation process after the sorghum valley plays an important role in improving the efficacy of subsequent processes; it also has important significance for the comprehensive utilization of husks.
Since the husks are lighter than rice and brown rice, they differ greatly in both bulk density and specific gravity. For example, the bulk density of rice is generally about 560 kg/m3, the bulk density of brown rice is about 760 kg/m3, and the bulk density of husk is only 110 kg/kg. Around m3, which is 1/5 of the weight of rice, 1/7 of brown rice, so their levitation speed is also very different. By measuring, the husk suspension speed is 1.5 to 2.0 m/s, while the rice levitation speed is about 8 m/s, and the brown rice is larger. Therefore, the principle of chaff separation is to use the role of wind force to achieve the purpose of sorting according to the significant differences in the above physical properties.
