DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a food tray device for a heat sterilizer.

[0002]

2. Description of the Related Art Conventionally, in a large cooking pot for cooking a large amount of ingredients at once, the ingredients are placed on a large tray, the tray is pulled up by a hoist or a winch and lowered into the cooking pot, and the trays are sequentially placed thereon. Are stacked and housed, and the lid is closed and cooked and sterilized. When the cooking sterilization is completed, the tray is opened, and the tray is pulled out one by one using a hoist or winch and taken out. Immediately after completion, the tray and ingredients are still at a high temperature, and it is dangerous to hook the hoist or winch onto the tray, and wait until the inside of the kettle drops to a certain temperature (about 40 ° C) and pull it up. In order to take out the cooked food from the drawn tray and pack it, the work must be done on a tray-by-tray basis, which requires a tray stocking area and a large work table, and the workability of packing is poor. If the packaging operation is delayed, the cooked foodstuffs are exposed to the open air for a long time, and the foods that have been sterilized can be cross-contaminated by bacteria in the open air. Therefore, when a certain period of time has elapsed after cooking, it is necessary to sterilize again before packaging the foodstuffs and then package the foodstuffs, and this re-sterilization processing requires wasteful energy and labor. In addition, when cooking small or small quantities of various varieties, it becomes a complicated task to separately place small or small quantities of various kinds of ingredients on a large tray and separate them at the time of packaging and pack them separately. Workability is impaired.
