What is the reason for sticking to small spray dryer?

The reason why the spray dryer has sticky walls in dry semi wet materials is that the droplets have been contacted with the wall before they reach the surface, so they stick to the wall The position of the sticky wall is usually the location of the droplet movement track against the wall It is related to the structure of atomizer and the movement of hot air in the tower The reason why the spray dryer is sticky when drying low melting point materials is that the material melts and melts at a certain temperature, so it adheres to the wall The small spray dryer is mainly suitable for the production of micro particle powder in the laboratories of universities, research institutes and food pharmaceutical and chemical enterprises, and has wide applicability for all solutions, such as emulsions and suspensions It is applicable to the drying of heat sensitive substances, such as biological products, biological pesticides, enzyme preparations, etc because the materials ejected are only exposed to high temperature when they are sprayed into aerosol size particles, they are only heated instantaneously, which can keep the active ingredients of these active materials from being damaged after drying.
