Granulation equipment is widely used in the evaporation and concentration process of liquid materials in the pharmaceutical, chemical, food, light industry and other industries. This equipment adopts the working principle of tube-and-tube circulating external heating. The heating time of the material is short, the evaporation speed is fast, and the concentration ratio is large, effectively maintaining the original effect of the material. The energy-saving effect is significant, saving about 70% of the steam volume than the single-effect evaporator. The material is evaporated and concentrated in a closed system, and the environment is clean and comfortable; the system is equipped with a unique defoaming device to prevent the phenomenon of material running. All parts in contact with materials are made of imported stainless steel and polished. The equipment has good corrosion resistance and is more convenient to clean. It is more in line with the requirements of pharmaceutical and food hygiene regulations. It can be equipped with a microcomputer control system, which is easier to use and more stable.
