WORKING PRINCIPLE

The machine is used in organic film, water soluble film and sugar film. Put the chip into the coating roller, the chip unceasingly makes complicated tracing movements in the clean and hermetic rotating coating roller. In the movements, following the craftwork flow and reasonable craftwork parameters, coating medium is automatically sprinkled, at the same tine, hot air is supplied under a negative pressure, which is vented out through the chip layer from the bottom of the coating medium sprinkled on the chip surface gets dried promptly and equally with forming a solid and sleek surface film.

1.As required by the latest version of national “GMP”, the quantitative index instruction operation is applied as possible as it could in the medication production craftwork process. This machine model applies man-machine converse interfaced formed by color contact screen and microcomputer produced by German Siemens and a long-distance control (interface). It has the negative pressure valve display, exhaust fan’s rotation speed display and control, supplied hot air volume display, air heater’s rotation speed display control, main machine’s rotation speed display and control temperature display, setting and control and pulp atomization control in the coating roller, so that digital quantity replaces the simulation and implementation of the post operation method, parameters are operated with the same control, produced medication in different lots to make the lot gap controlled in the minimun scope. Ensure stability of the medication quality.

2.Under the streamline Diversion plate blender’s effect, the prime pistil overturns fluently, exchanges frequently and excludes the collision phenomenon when the prime pistil falls from high, settles the fragment and knocked edge and enhances finished product ratio. Surface of the diversion plate is narrow and small with excluding adherence of dressing to its surface, saving the dressing and improving medication quality.

3.The creeping pump With constant variable precludes return pope. The return radius of the roller varies any time with pressure change, output and pulp spraying quantity automatically balance, which stabilize the atomization effect, simplify the atomization system, prevent spray gun clogging and save dressing, what’s more, it is simple to clean and without any dead angle.

4.The spray gun especially designed and manufactured for the coating machine is in that the atomization is equal, the spraying is large and the universal adjustable nozzle is independent from loading volume; timely cleaning to the gun clogging may make the coating continually go on, dwindle coating time and save the coating dressing

5.Possess negative pressure display and control inside the coating boiler.

6.Possess supplied hot air’s speed display and control

7.Possess spray gun anti-clogging function.

8.Possess memory and printing functions.

9.The above functions enables related technical parameters to realized quantitative display and control, the SOP operation method formulation turns feasible and uses quantitative index instruction for the operation, consistency of medication quality in every lot is guaranteed with totally in line with the GMP requirements.
