Indoor climatization device is an auxiliary equipment for chocolate coating applications. It is designed to supply dehumidified cold air to a belt coater or coating pan. Provided conditioned air from the air cooling device will help to solidify the liquid chocolate covered on the centers. Air conditioner for chocolate panning sucks in ambient air and filtered air from the coating machines. It removes moisture from the air and cools it to feeds back to chocolate panning machinery. It can supply cold air to single coating cabin or two coating pans. Output of the air cooler has to be connected with a flexible aluminum hose to the hood of belt coater or to the blower of the coating pan.
