Description

[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a food vacuum cooler.

[0002]

2. Description of the Related Art A conventional food vacuum cooler is provided with an in-vessel vapor discharge nozzle 9 in a food storage tank 1, and the inside of the storage tank 1 is depressurized by sucking steam from the nozzle 9 by a cold water ejector 2; The ejector 2 and the circulating pump 3 are interposed in a cooling water circulating water supply pipe 4, and both ends of the water supply pipe 4 are connected to a cooling water tank 5.
The cooling water in the cooling water tank 8 is cooled by circulating the cooling water in the cooling water tank 8, and the cooling water water 8 is supplied to the ejector 2 by the water supply pipe 4 (see FIG. 2).

[0003] For this reason, fine contaminants in the food storage tank 1 enter the water supply pipe 4 via the ejector 2 along with the steam from the steam discharge nozzle 9 in the tank, and further enter the cooling water tank 5 to contaminate the cooling water tank water 8. However, there was a problem that the cooling water tank water 8 clogged the small-diameter pipe 10 (chiller pipe) circulating through the cooler 6 and caused a failure.

[0004]

SUMMARY OF THE INVENTION It is an object of the present invention to provide a food vacuum cooler capable of cooling the cooling water tank 8 without any trouble even if the cooling water tank 8 in the cooling water tank 5 is contaminated with fine solids. With the goal.

[0005]

In order to achieve the above-mentioned object, according to the present invention, a cold water ejector sucks gas from a food storage tank to reduce the pressure in the storage tank, and connects the ejector and a circulating pump to a cooling water circulating water supply pipe. In a vacuum cooling device in which both ends of the water supply pipe are connected to a cooling water tank, a cooling pipe of a cooler is provided in the cooling water tank, and the water in the cooling water tank is cooled by the cooling pipe. Constituted by a food vacuum cooler formed as described above.

[0006]

[Function] In this invention, the heated or steamed food 1 is stored in the food storage tank 1.
The cooling pipe 6 is operated to cool the cooling pipe 7, and the water in the cooling water tank 5 in the cooling water tank 5 can be cooled by heat exchange.

In this state, the circulating pump 3 is operated to feed the water tank water 8 to the water supply pipe 4, and when the water tank water 8 is circulated, the water tank water 8 passes through the cold water ejector 2, and at that time, the food storage tank The gas (steam) in the container 1 is sucked into the ejector 2 and the gas is discharged from the container 1 so that the inside of the container 1 is decompressed or evacuated, whereby the food 12 is cooled.

Fine dirt entering with the gas sucked into the ejector 2 accumulates in the water tank 5 from the water supply pipe 4. However, since the dirt does not enter the cooling pipe 7, the dirt is generated by the dirt. The tank water 8 is contaminated by the cooling pipe 4
It has no effect on the cooling action.

[0009]

[Example] In a food storage tank 1, food 1 such as freshly cooked rice is placed.
2 can be accommodated and sealed.
The storage tank 1 is provided with a gas discharge nozzle 9, which is opened on the side of the cold water ejector 2, and the gas such as steam in the storage tank 1 is discharged by the action of the ejector 2.
From the storage tank 1
The food 12 can be forcibly cooled by reducing the pressure or vacuum inside.

The ejector 2 is provided on a cooling water circulating water supply pipe 4 and a circulation pump 3 is provided on the water supply pipe 4. Then, both ends of the water supply pipe 4 are connected to the cooling water tank 5, and a vacuum cooling device for the food 12 is formed.

In the cooling water tank 5, a cooling pipe 7 of a cooling machine 6 is provided.
(Chiller pipe) is inserted, and the water tank water 8 is cooled by the cooling pipe 7. In the figure, reference numeral 13 denotes a cooling pipe 7
, 14 is a blower of the cooler 6, 15 is a cushion tank of the cooler 6, 16 is a thermometer, 17 is a circulation pump of the cooler 6, and 18 is a temperature sensor of the water tank water 8.

[0012]

According to the present invention, as described above, when the food 12 in the food storage tank 1 is forcibly cooled, fine ejected from the tank 1 into the cold water ejector 2 along with gas is applied to the ejector 2 by the fine contaminants. There is no possibility that the cooling operation of the supplied cooling water tank water 8 will be affected, and it is possible to prevent the cooling device 6 from being damaged due to the waste.
