In a pan coating apparatus including a rotary drum which rotates about a horizontal rotation axis, an air supply chamber having a larger sectional area than that of an opening portion is arranged on a front stage with respect to the front-surface opening portion of the rotary drum. The air supply chamber is formed in a chamber door attached to a front of a casing, and has one end side communicating to the opening portion and another end side connected to an air supply duct via an air supply hole. The air flowing into the air supply chamber from the air supply duct is reduced in flow rate in the air supply chamber and supplied from the opening portion into the rotary drum with the air flow thereof in a stable state.

Pan coating apparatus

A spray gun () is attached to a multi-function unit () movable in a horizontal direction and a perpendicular direction. The spray gun () is mounted to a support holder (), and the support holder () is connected to a support arm () of the multi-function unit (). The support arm () is attached to a unit cover () which is openable/closable with respect to a casing (). The support holder () and the support arm () can hide and house a liquid hose and an air hose therein so that the hoses and the like are arranged in an apparatus in such a state as to be completely free from being exposed. An installation position of the spray gun () can be finely adjusted by the multi-function unit () during a coating process, thereby enabling a control for keeping constant distances between tablet surfaces and the spray gun ().
