ABSTRACT:
The present invention is directed to an apparatus for coating a product such as a medicament in the shape of a tablet. The apparatus includes a plurality of plates for receiving and retaining the products and means for advancing the plates on a conveyor to various processing stations. At a dipping station, a dipping means lowers and raises at least one plate into a first coating tank for coating at least a portion of the product. At a rotating station, a rotation means rotates one of the plates containing the product for spreading the coating on the product. After rotation, a first elevator transfers the plates from the conveyor to a dryer disposed above the conveyor. A second elevator transfers the plates from the dryer back to the conveyor for further processing. The dryer includes complementary acting pusher bars for transporting a plurality of plates horizontally along a plurality of vertically spaced guides. The plates are transported upward to traverse the guides through a first section of the dryer and downward through a second section of the dryer by the combined action of the first and second elevators and a mid-elevator. Several embodiments for the elevator are disclosed which include a lift bar mechanism, a continuous chain mechanism and a lift rod system.
