Pan coating apparatus

Abstract

A spray gun ( 31 ) is attached to a multi-function unit ( 32 ) movable in a horizontal direction and a perpendicular direction. The spray gun ( 31 ) is mounted to a support holder ( 33 ), and the support holder ( 33 ) is connected to a support arm ( 35 ) of the multi-function unit ( 32 ). The support arm ( 35 ) is attached to a unit cover ( 36 ) which is openable/closable with respect to a casing ( 2 ). The support holder ( 33 ) and the support arm ( 35 ) 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 ( 31 ) can be finely adjusted by the multi-function unit ( 32 ) during a coating process, thereby enabling a control for keeping constant distances between tablet surfaces and the spray gun ( 31 ).
