Abstract
The instant invention is directed to an apparatus for frosting drinking glasses. The apparatus is a self contained flash freezer designed for placement on a countertop wherein a miniaturized refrigeration system is mounted directly above a flash freezing chamber. Drinking glasses are placed upon a sloped roller bed used for transferring of the drinking glasses which are subjected to temperatures of about -30 degrees Fahrenheit causing frosting of the drinking glasses in less than one minute. The frosted glasses can be removed from a second opening of the chamber disposed at the lower end of the sloping roller bed. During normal operation, the apparatus is sized to handle a number of glasses and the sloped roller bed permits insertion of untreated drinking glasses which in turn forces the exit of frosted drinking glasses. For optimum frosting the apparatus accepts wet drinking glasses as the roller bed permits excess water to fall on a defrosting pan designed to vaporize excess moisture within the chamber for controlling the amount of frosting applied to the drinking glasses.
