industrial distilled water machine is an important equipment for the production of sterile water for injection in the pharmaceutical industry, to meet the production needs of pharmaceutical, food, beverage, electronics and other industries, in line with GMP requirements. Multi-effect water distillation machine can evaporate and concentrate the foaming material, because the liquid is evaporated in the heating tube in the form of film, that is, the formation of vapor-liquid separation, at the same time in the bottom of the body, most of the liquid is pumped away, only a small part of the liquid and all the secondary steam into the separator to strengthen the separation, the liquid does not form too big impact throughout the process, to avoid the formation of foam.
