摘要

In the coating of food wherein a food article is immersed in a tank containing a solution of a coating agent in a solvent, removed from the solution, allowed to drain, and removed from the tank, the improvement which comprises removing the solution from the tank while leaving the food article therein, maintaining a substantially liquid-free solvent vapor-laden atmosphere within said tank containing said coated food article while said food article drains, drawing off solvent vapors from said tank and thereafter removing said coated article from said tank, draining of said article in said solvent vapor-laden atmosphere within said tank resulting in formation of a level coating prior to setting of said coating upon removal of the solvent therefrom. The food article may be subjected to a flow of warm air prior to coating so as to remove moisture therefrom and permit better adhesion of the coating. To carry out the process there is provided an apparatus comprising a working tank, a sealable cover therefor, a tank for storage of coating solution, a pipe connecting said working tank with said storage tank, a reversible pump for pumping solution in either direction between said working tank and said storage tank through said pipe, a pair of pipes connected with said working tank, and means for introducing gas through one of said pair of pipes and for removing gas through the other of said pair of pipes, whereby volatile liquids and gases within said working tank may be removed therefrom.
