Principle and use steps of coating machine

Principle of the coating machine: 　　 Under the action of the rotation of the coating drum, the element core continuously moves in the drum. The peristaltic pump transports the coating medium to the spray gun to coat the surface of the core. Under negative pressure, the inlet air processing unit supplies clean hot air to the tablet bed according to the set procedure and process parameters to dry the core; The hot air is discharged from the bottom of the raw core layer through the exhaust air processing unit, so that the coating medium sprayed on the surface of the raw core quickly forms a strong, dense, smooth and smooth surface film to complete the coating. Use steps of the coating machine: 　　1 Check whether the various parts of the machine are in good condition and whether they are clean and hygienic, and disinfect according to the 'Efficient Coating Machine Disinfection Regulations'.　　2 According to the amount of coating and the shape of the medicine, install a rubber sheet of appropriate thickness, and pay attention to the angle and quantity of the magnetic needle board. Install and adjust the spray device, and check whether the operation, pot body, blower, spray and other devices can operate normally.　　3Set the required working time on the timer before turning on.　　4 Adjust the flow rate of the infusion pump per minute, whether the pressure of the compressed air meets the requirements, the temperature of the electric heating hot air, the air flow, and the angle of the spray gun to the best state.　　5 The position of the vacuum paddle should be adjusted to the top of the spray gun during the coating work, and it should be adjusted to the vertical upward position after the coating work is completed, so as not to affect the film ejection.　　6 After the operation is completed, turn off the air compressor, electric heating wire, heater, motor, and film coating switch in turn.
