JPH0549459A - Apparatus for sterilizing and cooling food packed in container - Google Patents

Abstract

PURPOSE:To enable the treatment of a number of food-containing containers without necessitating a large installation area by extending horizontal transfer conveyors at the right and left sides of a heating tank and a cooling tank and providing inlet and outlet conveyors in square forms to perform the introduction of container-supporting frames into the tanks and the discharge of the frames from the tanks. CONSTITUTION:The supporting rod 9 of a frame 8 for supporting a foodcontaining vessel V is supported by conveyors 6 and the vessel is passed through a heating tank 1 and a cooling tank 2 in a state immersed in the heating or cooling medium. The conveyors are horizontally extended at the right and the left sides of the tanks 1, 2. Inlet and outlet conveyors 20, 30 for introducing and discharging the supporting frame holding the vessel are extended outside of the horizontal conveyors in the form of squares.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for sterilizing and cooling food in a container, in which food such as jelly is put in a container for one meal and heat-sterilized and cooled in large numbers.

[0002]

2. Description of the Related Art Since a container containing this type of food needs to be sterilized for 30 minutes, then cooled and dried, a wide boil tank and a cooling tank have been conventionally used, and in addition, a dry area is required. Therefore, there is a drawback that it cannot be sterilized unless there is a vast place.

[0003]

The object of the present invention is to solve the conventional inconvenience, and to sterilize and cool a large number of food-containing containers continuously without reasonably requiring a vast space as in the prior art. The purpose is to obtain a device that can achieve the desired purpose.

[0004]

The means of the present invention are as follows.

On the left and right sides of the heating tank and the cooling tank whose upper surfaces are open, horizontally installed conveyors for supporting and gradually moving the supporting rods of the supporting frames of a large number of food containers immersed in the tank, Also, a sterilizing and cooling device for food in a container in which a loading / unloading conveyor for moving the container support frame in and out of the tank is arranged in a rectangular shape.

Embodiments and Functions The embodiments shown in FIGS. 1 to 5 will be described. In the figure, 1 is a boil tank, 2 is a cooling tank, and 3 is a drying device.

As shown in FIG. 3, supporting rods 4 and 5 are vertically arranged on the outside of the front and rear sides of the boiling tank 1 and the cooling tank 2 respectively.
It is permanently fixed, and a series of chain conveyors 6 and 7 are horizontally installed and supported on it. Reference numeral 8 is a sprocket for the chain conveyors 6 and 7. The chain conveyors 6 and 7 are provided with a receiving piece 10 that supports a supporting rod 9 of a supporting frame 8 that supports a large number of food containers a at regular intervals (see FIG. 5). ) Install many. The support frame 8 has holes 8c at the upper ends of the pair of frame plates 8a and 8b inserted through the support rod 9, and the container mounting plate 8d is fixed between the frame plates 8a and 8b in several stages. (7 steps in the illustrated embodiment) 12 is a mounting plate 8d
It is a stable rod that lightly presses the V rows of the containers placed side by side in series, and both ends are inserted into the holes 8e of the frame plates 8a and 8b. Hole 8e
Are opened stepwise to accommodate containers V of different heights.

Reference numeral 20 denotes an in-and-out conveyer for lowering the support frame 8 containing the container in the boil tank 1 which is erected further outside the chain conveyors 6 and 7, or pulling up the support frame 8 in the boil tank together with the container. As shown, the support rod 9 with the support frame 6 without a container supported by the receiving piece 22 of the conveyor 20 moving slowly in the direction of the arrow X in FIG. 8d is supplied and settles in the boiling tank 1, where it is supported by a chain conveyor. The chain conveyors 4 and 5 move at a slow speed and are heat-sterilized with the hot water in the boil tank for 30 minutes.
The next cooling tank 2 is lifted by the container discharge conveyor 23.
It is sent to the support frame 8 supported by the conveyor 30 of FIG. The structure of the conveyor 30 laid in the cooling tank 2 is the same as the structure of the conveyor 30 provided in the boil tank 1 and has a receiving piece, and the discharge conveyor 32 has only that container of the drying device 3. It is sent to the conveyor 3a. In the embodiment shown in FIG. 6, the cooling tank 2 and the drying device 3 are provided below the boil tank 1 to form a three-dimensional structure, and the occupied area for sterilization, cooling and drying is narrowed.

[0009]

According to the present invention, the intended sterilization and cooling work of a food container can be smoothly performed in a small area, and there is a practical advantage that a vast space is not required.
