1. Turn on the centrifugal fan and check the operation of the fan equipment: whether there is vibration, abnormal sound, odor, etc. of the high-speed centrifugal spray dryer, whether the temperature of the motor and bearing is normal, and whether the anchor screws are loose.
2. (Turn on steam heating first) Turn on the electric heater (electric heating is for auxiliary heating), and check whether there is leakage (if there is leakage, the control cabinet will automatically trip). Carry out preheating of the cylinder body, and the preheating temperature is between 180-220 °C.
3. Turn the fan on and off.
4. Place the centrifugal spray head, turn on the centrifugal spray head, slowly adjust the frequency of the atomizer to a certain frequency (determined according to the actual situation), let the spray head reach a higher speed under the condition of the frequency, turn on the feed pump, turn on the Outlet valve for feed pump. At the same time, open the pollinator at the bottom of the cylinder and the bottom of the cyclone to accept the material. (During continuous production, it is not necessary to clean each batch of materials. It needs to be determined according to the corrosiveness of the materials. When washing the centrifugal nozzle, it is usually not necessary to disassemble it. Use a screw pump to clean it with clean water.)
5. Slowly open the valve of the centrifugal nozzle, so that the amount of material is increased from small to large, otherwise it will cause sticking to the wall until it is adjusted to the appropriate demand, so as to keep the exhaust air temperature constant.
6. The dried product is collected, and in the pollinator at the lower part of the tower body and the lower part of the cyclone separator, it should be replaced before the pollinator is full. When replacing the pollinator, the butterfly valve above must be closed first.
