Abstract: An apparatus for storing and then defrosting frozen food has a first cabinet with trays of food on a conveyor to which food from the first-mentioned trays is transferred for individual defrosting, and a pair of removable members in the second cabinet for forming an enclosure about a tray therein while the food thereon is irradiated with microwaves, the tray with the defrosted food thereon being thereafter moved to a dispensing opening of the second cabinet.

Abstract: A defrosting apparatus for frozen food comprises a casing defining a chamber and a tray circulating system to circulate the trays, which are removably mounted thereon, along a fixed path in the casing while each of the trays always retains a horizontal position. A cover is provided in the upper portion of the casing and consists of a pair of half members for defining an enclosed chamber for enclosing a predetermined one of the trays. The apparatus includes a micro-wave irradiator for irradiating micro-waves onto the tray when the tray is enclosed by the cover, various kinds of atmosphere conditioners provided in the chamber of the casing, and a control system for controlling the circulation of the trays in the chamber and for closing and opening the half members and the micro-wave irradiation onto the tray within the cover.
