Description

Horizontal polishing machine for rice processing and application method thereof Technical Field The invention relates to the technical field of rice processing equipment, in particular to a horizontal polishing machine for rice processing and a using method thereof. Background In the rice finishing process, the polishing procedure is a key link for improving the surface glossiness of rice grains and removing surface bran powder. The horizontal polishing machine rotates the polishing roller to cause friction between the rice grains and the roller body and between the rice grains, and the horizontal polishing machine is matched with the function of a proper amount of atomized water to enable the surfaces of the rice grains to be smooth. In the prior art, various spray control schemes of rice polishing machines have been proposed. For example, chinese patent CN201720182072.1 discloses a horizontal polishing machine, which is provided with a sprayer consisting of a plurality of spray heads on the side of the polishing machine, each spray head works independently to achieve even rice water. According to the scheme, although the water uniformity is improved through the arrangement of the plurality of spray heads, the spraying quantity is still fixedly controlled, and cannot be dynamically adjusted according to the actual working state of the polishing roller. In addition, chinese patent CN201110155768.2 discloses an automatic control method of a rice polishing machine, which mainly includes a process of automatic control of water tank temperature and automatic control of spray flow, and the temperature and flow of a water supply system are regulated by a control system. However, the control scheme of the electronic sensor matched with the electromagnetic valve is adopted, so that in the polishing working environment with high humidity and high dust, electronic elements are easy to pollute and corrode, the problems of sensor failure, electromagnetic valve clamping stagnation and the like are caused, the equipment reliability is poor, and the maintenance cost is high. In the actual polishing process, the rotation speed of the polishing roller is closely related to the conveying speed and the residence time of rice in a polishing cavity, when the polishing roller runs at a low speed, the conveying speed of the rice is lower, the residence time of rice grains in the polishing cavity is longer, if the spraying amount is too large, the surfaces of the rice grains are easy to be excessively wet, so that the rice grains are adhered, whitened and even mildewed, and when the polishing roller runs at a high speed, the conveying speed of the rice is higher, the residence time of the rice grains in the polishing cavity is shorter, and if the spraying amount is insufficient, bran powder cannot be effectively removed, and the polishing effect is unsatisfactory. However, the existing equipment cannot synchronously adjust the spraying amount according to the change of the rotating speed, and an ideal polishing effect is difficult to maintain under different processing working conditions. Therefore, a horizontal polishing machine capable of automatically adjusting the spraying amount along with the rotation speed change of the polishing roller and having a simple and reliable structure is needed, so that the precise matching of the humidifying amount, the rice conveying speed and the friction strength is realized, and the stable and high-quality polishing effect can be ensured under different processing working conditions.
