1、 The spray dryer has some disadvantages. After the dry air enters, the air temperature is too low. The external air enters the drying room through the equipment vacancy, and the evaporation of the equipment will decrease significantly.

The solution to this situation is to check whether the operation of the fan is normal, whether the outlet of the centrifugal fan is equipped with a butterfly valve, whether the valve is opened, and whether the equipment is damaged. If any abnormality is found, it should be handled in time.

2、 Incorrect operation method. When operating the spray drying equipment, first turn on the centrifugal fan, then turn on the electric heating, and check whether there is air leakage. If it is normal, the barrel can be preheated.

The evaporation adjustment of drying equipment shall be selected for hot air preheating. On the premise of not affecting the quality of dry materials, the inlet air temperature shall be improved as much as possible, otherwise the evaporation adjustment of equipment may be affected.

3、 The air outlet of the equipment is blocked. At this time, it is necessary to check whether the outlet is clean and blocked. If any, it shall be handled in time.

In addition, the quality of spray drying equipment is also the key to adhere to the stability of equipment and ensure the harmonious service life of evaporation. When purchasing equipment, users should try to shop around, select products with quality assurance from qualified manufacturers, and timely seek help and deal with defects in case of problems.

Each customer has its own materials. How can we find out what type of spray drying equipment is suitable for its own materials? This is mainly selected according to the material and the product function required. For example, if my material needs granulation, I will go to know about the spray granulation dryer. Here, I can also consult the manufacturer. The manufacturer will select the equipment type for you according to your material characteristics and requirements, and can also conduct tests to see the effect first.
