Circulating cooling device for rice processing

Abstract

The invention discloses a circulating cooling device for rice processing. The circulating cooling device comprises a cooling box and a storage box, a negative pressure pipe is sleeved between one side of the cooling box and one side of the storage box, a fixed cylinder is mounted on the inner wall of the end, away from the negative pressure pipe, of the cooling box, a rotating shaft is sleeved with the fixed cylinder, a motor is mounted on a top plate of the fixed cylinder, an output shaft of the motor is connected with the rotating shaft, and a spiral auger is mounted on the rotating shaft. The top of the side wall of the fixed cylinder is connected with a guide plate, the top of the cooling box is sleeved with a feeding plate, a top plate of the storage box is provided with an exhaust fan, and a bottom plate of the storage box is provided with a discharging mechanism. Rice falls onto the guide plate through the feeding plate and is evenly scattered into the cooling box, the exhaust fan exhausts air, the negative pressure pipe exhausts air into the cooling box to form airflow, the rice is air-cooled, small broken rice is sucked into the storage box through negative pressure of the negative pressure pipe, and intact rice falls onto the bottom of the cooling box and is spirally conveyed to the guide plate again through the spiral auger, so that circulating cooling is realized.

Description

technical field [0001] The invention relates to the technical field of rice processing, in particular to a circulation cooling device for rice processing. Background technique [0002] In the rice processing steps, the rice after rice milling often has a higher temperature and needs to be cooled. The current cooling method is to simply stack and dry it naturally, but the natural air-drying method has a relatively slow drying speed and high efficiency. It is also low, especially the internal rice cannot be cooled quickly, which may easily lead to rice deterioration. Therefore, we propose a circulating cooling device for rice processing to solve the above problems. Contents of the invention [0003] The object of the present invention is to provide a kind of circulation cooling device for rice processing, to solve the problems raised in the above-mentioned background technology. [0004] In order to achieve the above object, the present invention provides the following tech...
