A starch raw material crushing and sedimentation device

Abstract

The invention discloses a starch raw material crushing and precipitation device. The starch raw material crushing and precipitation device comprises a machine case, a first cycloid motor and a second cycloid motor, wherein a water spraying nozzle, a screw rod extruding mechanism and a water wave turbine device are arranged in the machine case; the machine case is divided into an upper machine case and a lower machine case; the machine case is internally provided with a first driven rotary shaft, a second driven rotary shaft, a third driven rotary shaft and a fourth driven rotary shaft; a first fixed shaft and a second fixed shaft, which are welded and fixed on the machine case, are further arranged outside the machine case; the first driven rotary shaft is provided with a first cutting roller; the second driven rotary shaft is provided with a second cutting roller; eagle-break-shaped knives are arranged on the surfaces of the first cutting roller and the second cutting roller; the third driven rotary shaft is provided with a first grinding roller; the fourth driven rotary shaft is provided with a second grinding roller; coils are arranged at the bottom ends of the outer parts at the two sides of the lower machine case. The starch raw material crushing and precipitation device disclosed by the invention has the advantages of good crushing effect, high starch extracting rate, energy saving and environmental friendliness.

Description

technical field [0001] The invention relates to the field of starch production equipment, in particular to a crushing and sedimentation device for starch raw materials. Background technique [0002] In starch production, the washed starch raw material needs to be crushed and rolled to obtain a mixture of starch and water. The uniformity of crushing affects the thickness of rolling, and the thickness of rolling determines the quality of starch products. After deslagging, the mixture of starch and water is passed into the sedimentation tank for precipitation. After the starch and water are separated, the water needs to be emptied before the wet starch can be taken out of the sedimentation tank. This method of obtaining starch completely by standing still not only The efficiency is extremely low, and it cannot meet the needs of uninterrupted operation of the production line at all, and it needs to consume water resources to clean the sedimentation tank, and at the same time, se...

After the starch and water are separated, the water needs to be emptied before the wet starch can be taken out of the sedimentation tank. This method of obtaining starch completely by standing still not only The efficiency is extremely low, and it cannot meet the needs of the continuous operation of the production line at all, and it needs to consume water resources to clean the sedimentation tank, and at the same time, sewage will be generated
