Cooling device for rice processing

Abstract

The invention discloses a cooling device for rice processing in the technical field of rice processing equipment. The cooling device comprises a box body, supporting columns, a sliding mechanism, a discharging mechanism and an exhaust mechanism, the supporting columns are welded to four corners of the bottom of the box body, and the sliding mechanism is connected to the lower sides of inner cavities of the supporting columns in a sliding mode. According to the cooling device for the rice processing, the structure design is reasonable, the airflow blowing-in direction is changed while the airflow flowing speed is not reduced, the airflow makes full contact with rice, the cooling time of the rice is effectively shortened, a temperature sensor is arranged to detect the residual temperature in a rice pile, workers do not need to take out the rice and then detect the temperature, the actual operation steps of the rice cooling device are greatly reduced, then a one-way exhaust valve and a plate type filter element are used in cooperation, gas in the box body is exhausted, meanwhile, residual air in the box body is purified, the rice cooling efficiency is further improved, and meanwhile, impurities left on the surface of rice are effectively reduced.

Description

technical field [0001] The invention relates to the technical field of rice processing equipment, in particular to a cooling device for rice processing. Background technique [0002] In the process of rice processing, rice needs to be made into rice after multiple processing procedures such as impurity removal, rice husk separation, bran removal, grading, polishing, and color selection. Therefore, timely cooling of rice is of great significance for rice processing. [0003] However, the commonly used methods of cooling rice include natural air drying or using corresponding equipment to cool it with water or air. Traditional air-cooled cooling devices often have a vertical airflow angle, which makes the airflow ineffective while being blown in. It is in contact with the rice, and the flow velocity of the airflow is greatly weakened under the influence of the inner wall of the box, resulting in low cooling efficiency and greatly prolonged cooling time. On the other hand, the ...

Problems solved by technology

[0004] The object of the present invention is to provide a cooling device for rice processing, to solve the problem of the traditional air-cooled cooling device proposed in the above-mentioned background technology, the blowing angle of the airflow is often vertical, resulting in that the airflow cannot be effectively mixed with the rice when it is blown in. On the other hand, the traditional air-cooled cooling device does not have the function of temperature detection of the discharged rice and the function of controlling the speed of rice discharge, which leads to the need to manually detect the discharged rice again, which increases its actual cost. Operation steps, on the other hand, during the long-term purging process of rice, the hot air flow stays in the box for a long time, which greatly reduces the cooling effect of the rice, and cannot remove the remaining impurities of the rice, causing the problem of secondary pollution of the rice
