External circulation vacuum evaporator is a natural circulation type evaporator that operates in a vacuum system.
The evaporator has one effect, two effect, and three effect series specifications, and there is also a Q-type forced non circulating evaporator. This product can be widely used for evaporation and concentration of water or organic coal solutions in industries such as medicine, food, chemical, and light industry. Especially suitable for thermosensitive materials, such as water and alcohol extracts used in traditional Chinese medicine production, antibiotic fermentation broth, milk, fruit juice, etc. Continuous low-temperature concentration under vacuum conditions can ensure product quality. If you need to recycle alcohol and increase its concentration, the company has developed an external heating evaporation alcohol recovery and distillation device.
