Large spray dryer common faults and solutions
Large-scale spray dryers are highly regarded by many companies because of their fast drying speed, good drying effect and continuous production process. However, as the use time increases and the relevant parameters are set incorrectly, the spray dryer will cause some problems in the production process. After more than ten years of experience in the company, we have listed some common problems and solutions:

How to prevent the spray dryer from sticking to the wall?
The spray dryer sprays the material into droplets and disperses it in hot air. The materials are in contact with the hot air in a cocurrent, countercurrent or mixed flow manner, so that the water evaporates quickly to achieve the purpose of drying. By means of spray drying, unit operations such as concentration, filtration, and pulverization can be omitted, and drying time is short, product fluidity and fast solubility are good, and thus it is widely used in medicine and other industries.

Small Low Temperature Spray Dryer Sticky Wall Solution
The small low-temperature 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. 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, biological pesticides, enzyme preparations, etc., because the sprayed materials are only subjected to high temperature when they are sprayed into mist-sized particles, so they are only heated instantaneously, and these active materials can maintain their active components after drying.
