Abstract
A produce warmer for raising the temperature of cold produce taken from a cold environment and about to be processed includes a refrigerant circuit in which an evaporative cooler and a heat exchanger are arranged in series for circulation of a refrigerant between them. The direction is such that heat is taken from the heat exchanger and is transferred to the evaporative cooler. There is a first housing for warm produce to be cooled, and this housing is included in a secondary water circuit also inclusive of the heat exchanger. The water in the secondary circuit is circulated in a direction to pick up heat from the produce and to transfer such heat to the heat exchanger. Following this the returning cool water is sprayed over the warm produce in the first housing and is recirculated. Should there be no warm produce for the first housing, an alternative supply of heat is afforded by a fan introducing warm air to the first housing. A tertiary water circuit includes a second housing for produce to be warmed and also includes the evaporative cooler. In the tertiary circuit a pump takes relatively warm water from the evaporative cooler and sprays it over produce to be warmed in the second housing. The sprayed water, which has been cooled by yielding heat to and so warming produce in the second housing, is returned to the evaporative cooler, wherein it is again warmed and from which it is recirculated.
