Description

  The present invention relates to a vacuum cooling container used for vacuum cooling of foodstuffs in a large-scale cooking facility, and particularly relates to a container that can prevent the contents from being blown out.

  In a large-scale cooking facility, when a large amount of food is made, cooking is performed by heating the food. The temperature of the food immediately after cooking is 70 to 80 ° C., which is stored in a metal container, depressurized to about several kPa using a vacuum cooler, and rapidly cooled to lower the temperature of the food (for example, patents). Reference 1). Such a vacuum cooling method is generally intended for solids. On the other hand, in the case of foodstuffs containing liquids (hereinafter referred to as “liquid products”) such as boiled oden, stewed potatoes, soups, roux, etc., if the pressure is suddenly reduced, the water may boil at a low temperature and may cause spillage. Therefore, when cooling by the reduced pressure cooling method, it is necessary to gradually cool at a reduced pressure reduction rate. Moreover, it was necessary to cool under reduced pressure after cooling until it became about 50 degreeC, without reducing pressure immediately after cooking.

  The shielding intermediate plate 30 includes a disc 31 and a shaft portion 32 that protrudes upward from the central portion of the disc 31. The gap between the outer peripheral edge of the disc 31 and the inner wall surface of the main body container 20 is, for example, about 2 mm.

  A male screw 32 a is formed on the outer periphery of the shaft portion 32, and a hollow portion 32 b is formed on the shaft portion 32. A cylindrical collar 33 is fitted into the shaft portion 32. The outer diameter of the collar 33 is larger than the inner diameter of a through hole 41b of the lid 40 described later. A temperature sensor S is inserted into the hollow portion 32b. The output of the temperature sensor S is input to the control unit K.

  The lid 40 has a disc 41, and the outer peripheral portion of the disc 41 is bent to form an outer peripheral edge 42 provided in a concave shape below (see FIG. 2). A silicon packing 43 is attached to the outer peripheral edge 42 in an annular shape. The opening edge 21 of the main body container 20 is abutted against the lower surface of the silicon packing 43.

  A large number of small holes 41a are formed on the center side of the disk 41 (a position spaced apart from the outer peripheral edge portion 42 of the lid 40 in the horizontal direction), and the above-described shaft portion 32 is passed through the center portion. A through hole 41b is formed.

  A large number of small holes 51 a are formed on the center side of the bottom 51 of the middle container 50.

  As shown in FIG. 2, the close fitting 100 is provided directly below the opening edge 21 of the main body container 20, and is provided with a base portion 101 fixed to the outer wall surface of the main body container 20 and the base portion 101 in the vertical direction.

The horizontal shaft 105 and the horizontal shaft 107 are coupled with different axes so as to rotate in opposite directions.

  Using the vacuum cooling container 10 configured as described above, the food after cooking is vacuum-cooled as follows. That is, in the case of a liquid material containing a solid material, the solid material and the liquid are divided in advance, and the liquid is stored in the main body container 20. Next, the middle container 50 is disposed in the main body container 20 with the bottom 51 of the middle container 50 facing upward. Next, the solid material is placed on the bottom 51.

  Next, the shaft portion 32 is passed through the through hole 41 b of the lid body 40, and the thumbscrew 60 is screwed to couple the lid body 40 and the shielding intermediate plate 30. The distance between the lid 40 and the shielding middle plate 30 is determined by the collar 33. When the lid 40 is placed on the opening of the main body container 20, the shielding intermediate plate 30 is positioned on the solid material.

  Further, the hooking tool 106 of the close fitting 100 is flipped up and the engaging portion 104 is flipped up (see FIG. 1). The outer peripheral edge 42 of the lid 40 is aligned with the opening edge 21 of the main body container 20. Next, when the hooking tool 106 is pushed in, the engaging portion 104 is hooked on the outer peripheral edge portion 42 and fixed. As a result, the silicon packing 43 of the lid 40 and the opening edge 21 of the main body container 20 are in close contact with each other.

  Next, the decompression system G is driven by the controller K, and the interior of the decompression system G is decompressed rapidly. At this time, the liquid stored in the lower portion of the main body container 20 boils at a low temperature, and an upward flow of vapor, liquid, or the like is generated from the small hole 51a by the action of the decompression system G. The upward flow passes through the space between the shielding middle plate 30 where the solid matter is placed and the middle container 50, and passes between the shielding middle plate 30 and the inner wall surface 22 together with the vapor and liquid generated in the solid matter. .

  In such an upward flow, the liquid drops on the shielding middle plate 30, and the speed of the liquid decreases as it moves further. Next, the liquid in the upward flow that passes through the gap between the outer peripheral edge of the shielding middle plate 30 and the inner edge surface 22 of the main body container 20 has a small hole 41 a provided in the cover body 40 in the horizontal direction from the outer peripheral edge 42 of the cover body 40. Most of them hit the disk 41 and drop. Also, a part of the liquid moves in the horizontal direction and tries to rise from the small hole 41a, but most liquid does not rise by its size and weight, does not pass through the small hole 41a, It will drop on the disc 41 and return to the bottom side of the main body container 20. On the other hand, the steam is discharged to the outside through the small holes 41a. Therefore, the liquid does not spill from the vacuum cooling container 10.

  On the other hand, by storing the liquid and the solid separately, the solid does not collapse due to the upward flow generated in the liquid.

  In addition, by always monitoring the temperature change with the temperature sensor S, an appropriate pressure reduction rate and cooling are realized.

  By using the reduced-pressure cooling container 10 in this way, even a food containing liquid can be rapidly cooled by the reduced-pressure cooling method, and in the case of a food containing a solid and a liquid, the shape of the solid is lost. Can be prevented. Further, since the entire container is not contaminated by low temperature boiling, the workability is good and the work can be performed in a sanitary manner.

  In the present embodiment, the liquid is a mixture of solids as a food material. However, the intermediate container 50 may be removed and used in the case of only liquids or when there are few solids.
