Working principle
Under the rotation action of the coating roller, the tablets or pills to be coated make continuous movement in the roller. The peristaltic pump conveys the coating media to the spray gun for spraying them on the surfaces of the tablets or pills to be coated. Under negative pressure, the inlet air handling unit supplies clean hot air to the tablet bed according to the set procedures and process parameters to dry the tablets or pills. The hot air is discharged from the outlet air handing unit at the bottom of the layer of tablets or pills, so that the coating media sprayed on the tablets or pills rapidly form solid, dense, flat and smooth film to complete the coating operation.
Features
▲The control system consisting of PLC and HMI is designed reasonably with flexible programming, meeting various pharmaceutical process requirements with reliable work and stable performance and conforming to GMP requirements.
▲It adopts the new type spray gun with even atomizing, large spraying area, adjustable direction. The nozzle is not affected by the loading volume, the device for cleaning the blocked spray gun can ensure continuous coating, shorten coating time and save coating dressing.
▲Quantitative display and control of technical parameters are realized. SOP operation can be compiled to guide the operation by using quantitative indicators and ensure the consistency of quality of each batch of medicines, fully meeting GMP requirements.
