The equipment is applied for solution condensation in the industries such as traditional Chinese medicine, western medicine, foodstuff, monosodium glutamate, milk products, dextrose, amylum, syrup, chemical and so on. The scraping board concentrator is mainly made up of four parts, which are the main body with mixing device, condenser, cooler and liquid receiving bath. With the characteristics of original designing and special structure for the equipment, sphere(GNQ)or cone(GNZ) may be selected on assembling the blade of scraping board and tank cylinder, and the condensing or materials with high viscosity, of which the condensate specific, gravity could be more than 1.4To be customized
