ABSTRACT:
The invention relates to method and process for drying aqueous coatings such as water based wax and the like on fruit.
The fruit is taken from the cold storage area and immersed in heated water to raise the skin temperature to a level sufficient to be receptive to the coating. The coating is then applied to the fruit. Cold air, above the freezing temperature, is passed first up through the product, over it and down through it while it is carried on a porous conveyor. The cold air, heated by the warmer product and laden with water and solvents, is passed through a refrigeration unit. The water carrying the solvents is then removed. The dehumidified air is then recycled. The product may be exposed to a second sequential stream of cold air.
