Mini spray dryer is a kind of equipment that dries liquid material into solid material at high temperature. The glass structure makes the atomization process visible. Flexible and compact, easy to move. The equipment is equipped with a complete safety system such as heating protection and safety protection. It is mainly suitable for the production of micro-particle powder in universities, research institutes and laboratories of food, medicine and chemical enterprises. It has broad-spectrum applicability to all solutions such as emulsions and suspensions, and is suitable for drying heat-sensitive substances such as biological products and biological pesticides. , Enzyme preparations, etc., because the sprayed materials are only exposed to high temperature when sprayed into mist-like particles, so they are only heated instantaneously, which can keep these active materials from being damaged after drying.
