[0002] At present, the intermittent crystallization process in cooling crystallization accounts for more than 95% of all domestic industries. The labor productivity is low, mainly due to manual operation, the product quality cannot be guaranteed, and the comprehensive energy consumption is high. The supporting refrigeration system and brine low-temperature water system account for The ground area is large, the power consumption is large, and the corrosion is high. Some of them adopt the freeze crystallization process, and the pipe plugging and scarring are prominent. They need to be cleaned frequently, and the labor intensity is high. Flour), dehydration is difficult, agglomeration seriously affects the quality of the product
