DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a food storage provided in a cooking / sterilizing machine.

[0002]

2. Description of the Related Art Conventionally, in a large kettle for cooking a large amount of ingredients at a time, a tray containing the ingredients is hung by a hoist or winch, placed in the kettle, and stacked on the tray at intervals. Then, the pot lid is closed and cooking is sterilized. When the cooking sterilization is completed, the tray is pulled up one step by a hoist or winch and taken out. Immediately after cooking sterilization is completed, the trays and ingredients are still at a high temperature, and the tray is pulled up after waiting until the inside of the pot has dropped to a certain temperature (for example, about 40 ° C.). For this reason, the tray at the bottom of the kettle is placed in a high temperature state for a long time and cooking proceeds, causing a problem that the taste is reduced and oxidation is caused, thereby deteriorating the value of the product.
In addition, it takes time to remove and move, and during that time, the cooked food is exposed to the outside air, and there is a risk of secondary contamination by bacteria in the outside air, and the cooked food left in the outside air for a certain time is sterilized again. Needed. The inventor of the present invention placed a large number of trays containing ingredients on a rack provided with a number of shelves, and took out and moved the entire rack, thereby reducing the time required for taking out and moving the rack. Is trying to solve. However, even if the entire rack is removed from the kettle, cooked ingredients may be left unpackaged immediately due to the work procedure or the necessity, and during this time there is a risk of secondary contamination by bacteria in the outside air, Before packaging the food, it is sterilized again and then packed. This re-sterilization process wasted energy and labor and was not economical.

[0003]

In the present invention, cooked foods are taken out together with the rack at a relatively high temperature, stored in a food storage, and temporarily stored in a sterilized state.

[0004]

According to the present invention, a food storage for temporarily storing cooked ingredients is provided, a ceiling door is provided on a top surface of the food storage, and a tray extraction door is provided in front of the food storage. A disk-shaped rotating table is provided in the center, a multi-stage shelf is provided on a cylindrical rack, and a fan-shaped tray is freely inserted and removed from the outer periphery toward the center of each shelf, and cooked ingredients are The food is stored, the ceiling door of the food storage is opened, the rack is placed on a turntable, and it is sealed and stored. If necessary, the tray removal door is opened, and the cooked ingredients are sequentially selected and taken out together with the tray.

FIG. 7 is a front view of a cooking and sterilizing apparatus provided with a rack according to the present invention. An upper part of the shuttle 15 is provided with a shuttle lid 15a which is opened and closed by an electric motor. A rail 27 is horizontally installed above the shuttle 15 from above the center of the shuttle 15, and the winch 11 is suspended on the rail 27 so that it can run freely.
The rack suspender and the rack 1 are lifted by the hook 12 and moved along the rail 27. The food storage 18 is arranged near the shuttle 15 in the direction of the rail 27.

The operation of the present invention will be described with the above configuration. Cooking is completed in the pot 15, and the pot lid 15a of the pot 15 is opened. Then, the winch 11 is moved above the shuttle 15 and
The rack suspender is lowered, engaged with the suspension wheel 9 of the rack 1, pulled up by the winch 11, and the rack 1 is taken out of the shuttle 15. Further, the winch 11 is moved along the rail 27, is stored in the food storage 18, and is transported to the packing place. Even when the temperature of the cooked food is high, the rack hanger removes the rack 1 and the tray 3 safely without directly touching it, and moving at the high temperature may cause bacteria to adhere on the way. However, because of the high temperature, the bacteria can be sterilized and stored in the food storage 18.

The food storage 18 is provided with the ceiling door 2 in advance.
0a, 20b and tray take-out doors 24a, 24b are closed, and alcohol sterilization
9 is sterilized or sterilized. After heat cooking sterilization in the kettle 15, the rack 1 is pulled up from the kettle 15 by the winch 11 and moved to the position above the food storage 18, and the ceiling doors 20a, 20
b is opened and the rack 1 is placed on the turntable 26 by the winch 11. At this time, since the outer periphery of the rack 1 descends along the semi-lunar inner wall 28, the rack 1 can be easily mounted on the center of the turntable 26. Then, ceiling doors 20a, 20
b is closed to keep the inside of the housing 19 airtight. The rack 1 is confined in a narrow space surrounded by the inner wall, the side wall of the housing 19, and the tray extraction doors 24a and 24b. At this time, the product temperature of the cooked food is still at a temperature of about 40 ° C., and in this state, it is confined in a sterilized narrow space and cuts off contact with the outside air. In this state, the food storage 18 is transported to a sterilized packing place.

When packing the foodstuffs stored in the food storage 18, the tray taking-out doors 24a and 24b are opened, and the trays 3 are pulled out from the rack 1 for each tray 3 to perform the packing operation sequentially. At this time, even if the packaging of some foodstuffs may be delayed due to the procedure of the packaging work, only the necessary tray 3 is selected and taken out from the rack 1 and the others are left in the food storage 18 for sterilization. Can be kept in condition. In addition, when taking out the predetermined tray 3, the turntable 26 can be rotated to easily select and take out the predetermined tray 3, and the opening time of the tray take-out doors 24a and 24b can be shortened as much as possible, and the food storage can be performed. Prevent secondary bacterial contamination of other ingredients in the storage 18.

[0014]

According to the present invention, the rack with the tray on which the cooked ingredients are placed is taken out from the kettle, stored in a food storage box, and sealed. By taking out and packaging the food, the cooked foodstuffs in the remaining trays can be kept in a sterilized state. Further, the rack can be lowered on the turntable of the food storage, and the turntable can be rotated to sequentially select and take out the necessary trays easily and in a short time, and to pack the tray.
