Description

  The present invention relates to a rack transport cart that transports a rack that is stored in a storage supported at a predetermined height on a rack mounting table.

  In general, high-temperature foods that have been heat-treated by a steam convention oven (hereinafter referred to as “oven”) need to suppress the propagation of germs and maintain freshness, taste, nutritional value, etc., so blast chillers (hereinafter referred to as chillers) To cool rapidly. In this case, the food is placed on a multi-stage rack and is stored in an oven or a chiller for each rack, and a rack transport cart is used to transport the rack.

  By the way, when the manufacturer and the chiller are different from each other, the rack accommodation type is also different, and there are usually a vertical insertion type that is accommodated from the short side of the rack and a horizontal type that is accommodated from the long side of the rack. For this reason, when a vertical insertion type oven and a horizontal insertion type chiller are installed, it is necessary to take measures to accommodate the same rack in both the oven and the chiller. For example, if the chiller has enough space to allow both horizontal insertion and vertical insertion, and an attachment that supports racks of different sizes (types) is attached, it can be removed from the vertical oven. The rack can be vertically placed in the chiller, and the present applicant has already proposed a cooling device based on such a concept in Japanese Utility Model Registration No. 2575851.
