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.

Summary of precautions before and after use of spray dryer
Before using the spray dryer, the staff needs to complete the relevant preparations in advance. First of all, the material to be sprayed is thoroughly emulsified and homogenized by a homogenizer and passed through an 80 mesh screen. This is to avoid the occurrence of atomizers and pipeline blockage in the later stage. And these materials should be placed in stainless steel buckets for use. In addition, a bucket of tap water is used to clean the atomizer and spray chamber of the spray dryer.
