Detailed explanation of the reasons and solutions of spray dryer sticking to the wall

 

Spray dryer is a kind of drying equipment widely used in chemical, food, pharmaceutical and other industries. It can directly dry solution materials into powder products. The problem that often occurs in spray dryers is the problem of material sticking to the wall.

The problem of sticking to the wall is the most serious and most likely problem in the production of spray dryers. Below we will explain in detail the common reasons for sticking to the wall of spray dryers and the solutions.

一、Reasons for spray dryer sticking to the wall:

 

1. The size design of the spray tower fails, the tower diameter is too small, and the atomization radius is large, which causes the material liquid to directly contact the tower body after spraying, resulting in sticking to the wall.

 

2. The temperature of the hot air inlet is too low, so that the material has not been completely dried, that is, the semi-wet material is in contact with the tower body, and it is easy to form a sticky wall.

 

3. The hot air temperature is too high, exceeding the melting point of the material, and the melted material has a large viscosity and is easy to stick to the wall.

 

4. Other factors such as the material itself is a highly viscous material, hot air movement form factors and so on.

 

二、 the solution of spray drying sticky wall:

 

1. If the sticking wall is not serious and the transformation cost is too large, air scavenging, air hammer, rotary scraper and other devices can be added, which can effectively maintain the normal operation of the spray dryer.

 

2. Properly adjust the hot air temperature and wind speed according to the material characteristics (the main methods include improving the heat source, modifying the air distribution device, and improving the fan selection, etc.)

 

3. Replace with a suitable atomizer.
