Spray drying equipment is mostly a chemical industry, and the food industry is used to make solutions and suspensions into a kind of drying equipment. The use of materials and hot gas through full contact with the coexistence and other means, so that fast drying, is a powerful tool to obtain powdered products. Spray drying equipment has good drying effect and little dust pollution, so it is very popular in the industry. However, there are some problems in the spray drying equipment that will affect the drying effect of the whole material. So Xiao Bian analyzes briefly here, the problems and solutions that often occur during the use of spray drying equipment.

2. Into the air and exhaust air temperature is not appropriate, too high or too low. This situation is a stress issue. In the process of use, it is necessary to properly adjust the air intake and exhaust pressure of the machine.
3. The finished product after drying has high moisture content and poor drying effect. There are many possibilities for such a situation, materials, drying temperature, air intake, heating area, etc. may affect, so we should first find the reasons for the adjustment.
4. Dry finished product has impurities or color difference. Generally it is not cleaned in the air, it may be because the temperature during hot processing is too high or too low, and the whole material is in a form, resulting in color difference.
