Automatic Tablet Coater

Application & Process :

Shree Bhagwati Mechtech ( india) Pvt. ltd. advanced high efficiency automated tablet coating machine is mainly used in pharmaceutical and food industries. Featuring mechatronis and confirming to the requirement of cGMP. It is a high efficiency, energy saving, safe and clean equipment for film and sugar coating of tablets, Pills and candies with organic film, aqueous coating and sugar film etc.

Automatic Tablet Coater is designed for the application of:

• Film Coating with organic solvent, Enteric Coating and aqueous coating
• Sugar Coating

Working Principle :

The tablet to be coated make continuous complicated orbital motion the closed rotating Drum under the action of a streamline of Baffles. During the motion coating medium automatically sprays according to the technological process and rational technological parameters, at the same time hot filtered air supplied under a negative pressure. The hot air penetrates through the tablets core layers and is discharged from the bottom of the layers, so that the coating medium sprayed on the surface of the tablet cores will dry rapidly and evenly, thus forming a solid and smooth surface film on tablet. The whole process is finished under the automatic by PLC Controls with touch screen Interface.
