Pan coating apparatus

A pan coating apparatus, comprising:

• a rotary drum provided rotatably about a substantially horizontal rotation axis;
• a casing for housing the rotary drum;
• a unit cover attached to the casing so as to be openable/closable;
• a multi-function unit movable in a horizontal direction, the multi-function unit including a support arm attached to the unit cover and a support holder connect to the support arm;
• and
• a spray gun mounted to the support holder,
• wherein each of the support arm and the support holder is capable of housing therein a hose connected to the spray gun without exposing the hose to an outside,
• wherein the support arm and the support holder are connected to each other by a hinge so as to be rotatable relative to each other in the horizontal direction,
• wherein the spray gun is movable into and out of the rotary drum, and the spray gun is also movable in a vertical direction,
• wherein the support holder rotates relative to the support arm about an axis that is perpendicular to the rotation axis of the drum, and
• wherein the unit cover rotates relative to the casing about an axis that is perpendicular to the rotation axis of the drum, and rotation of the unit cover displaces the support holder and the spray gun.
