Automatic coating machine working principle use application

The auto coater consists of a control system, a hot air filtering system, coating pan, solution tank, and exhaust system. The film to be coated on the tablet is in liquid form before the process is started so the liquid is filled in the solution tank. The liquid is stirred well in the solution tank and then pumped into the coating pan. The coating pan is perforated and holds a batch of tablets that are to be coated. A set of spray guns are present at the center to spray the coating liquid on the tablets. The coating pan is able to rotate on its axis.

Hot air is passed in from a hot air blower which is passed through a series of filters to remove impurities. The filters used are a washable filter, pre-filter, and HEPA filter. The air from the blower is not hot initially so a steam heater is used to heat the air before passing it into the coating pan. The machine is operated by PLC controls from the control panel.

In the coating process, the tablets or similar products that are to be coated with film coating are filled in the coating pan. The coating liquid is pumped from the solution tank into the coating pan. The spray guns spray the tablets with atomized particles of

the coating solution as the perforated coating pan is rotated so that the entire batch of tablets is evenly coated. Simultaneously, the hot air from the blower is passed in to the drum at negative pressure which dries the sprayed coating evenly and rapidly which then causes it to become a solid and smooth surface film on each of the tablets.

The air is then exited from the perforated coating pan and moves to the exhaust system. The exhaust system consists of an exhaust blower to send the exit air from the coating pan to the external environment. The exhaust system consists of a dust collector which is also called a scrubber. In some systems, wet scrubbers are used to filter the particulates in the exhaust. The liquid droplets within the wet scrubber absorb the particulate matter thereby filtering the exhaust air before release.
