BRINE REFRIGERATOR DEVICE

PURPOSE:To realize a subdivided keeping temperature by a method wherein a plurality of temperature setting means for flowing brine are provided in order to make keeping temperatures in an upper holding chamber and a lower holding chamber different in respect to a brine pipe for each of rack plates within a refrigeration chamber. CONSTITUTION:As a circulation pump 20 and a compressor 31 are operated, brine cooled by a brine heat exchanger 22 passes through a supplying line 17, is supplied to a brine pipe 15 of each of rack plates 12 through an opening or closing valve 15a so as to cool each of holding chambers to be defined by each of the rack plates 12. A temperature of each of the keeping chambers is controlled to a different holding temperature through an intermittent supplying through an opening or closing of the opening or closing valve 15a or through a flow rate control of the brine via the opening or closing valve 15a. In this way, it is possible to satisfy a more preferable keeping condition according to the kind of fresh foods.
