Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for placing food such as Tsukudani on a table and allowing it to cool. More specifically, it is capable of cooling in a sterile environment.

[0002]

2. Description of the Related Art In general households, boiled boiled beans, boiled beans, etc. are boiled and then left naturally in a pot to cool before being transferred to a storage container or tableware. It is said that such natural cooling is the most rational for maintaining a long shelf life and the secret is that the taste is well soaked and delicious during natural cooling.

In food manufacturing factories, foods are manufactured by substantially the same method, but they must be mass-produced efficiently and efficiently without degrading the quality of these foods. However, in the cooling process, after the food is transferred to a relatively flat cooling container, it is placed on the cooling stand and waits for natural cooling, but during this process, various bacteria are mixed into the food from around the cooling stand. It is not hygienic.

Therefore, it is conceivable to provide a sanitary facility only for cooling the room in which the cooling stand is installed, but in this case, it is not flexible when it is desired to use the room for other purposes, and the equipment investment is expensive. Does not fit.

[0013] 5 sterilization lamp combined illumination provided appropriate number on the ceiling portion of the dust-proof hood 2, F 1 is the air blowing port to clean air is supplied from a not-shown blowing device (blowing means), K is the dust hood 2 lower It is a curtain hung from four laps. The curtain K is preferably made of a cloth such as a transparent and airtight nylon sheet.

FIG. 2 is an overall front view showing a second embodiment of the food dustproof cooling device, and FIG. 3 shows a fixing mechanism for supporting legs 6 thereof.

In the figure, 6 is a plurality of support legs integrally fixed to the four corners of the dustproof hood 2, and the lower ends of the support legs 6 are connected by a flat member 6a assembled in a rectangular shape. Reference numerals 7 and 7a denote fittings for fixing the support legs 6 to the workbench 1, 8 denotes a tightening bolt for tightening the fittings 7, 7a, and 9 denotes an operating handle for the tightening bolt. Reference numeral 10 denotes a magnifying lens which is detachably provided by a suction tool (not shown), and is formed such that its longitudinal direction matches the curved surface of the dustproof hood 2.

In the case of the middle portion of the side surface of the dustproof hood 2, an L-shaped mounting bracket 7a as shown in FIG. 4 is used to hold the flat member 6a for linking the legs 6 and 6 and the workbench 1. Turn the operation handle 9 to firmly sandwich both.

As the magnifying lens 10, a flat lens in which a large number of concentric grooves are concentrically formed on the surface of a transparent plastic plate is suitable. The magnifying lens 10 allows the food on the workbench 1 to be clearly observed from the outside.

As the magnifying lens 10, a lens containing water or oil inside may be used, and in this case, an extremely inexpensive device can be used.

The above-described first and second embodiments are exactly the same in the operation and effect, except that the support structure of the dustproof hood 2 is different. First, the curtain K hanging in the gap L between the dustproof hood 2 and the workbench 1 is opened, and food is placed on the workbench 1
Place it on top. Clean air is supplied into the dustproof hood 2 from the blower opening F 1 and the flow rate and flow velocity thereof are adjusted.

The sent air deprives the food of the amount of heat and flows out through the gap below the curtain K to the outside of the room. As a result, the inside of the dustproof hood 2 has a slightly higher pressure than the outside, the inflow of air from the outside is suppressed, and there is no risk that foreign bacteria will be mixed into the food in the dustproof hood 2 from the outside.

Further, the food is not cooled rapidly, but the air volume and the air speed can be adjusted so that the food is gradually cooled at an optimum speed, so that the food is not spoiled and the cooling work is performed in a time suitable for long-term storage. Is promoted. Further, the food can be observed through the dustproof hood.

In the figure, reference numeral 20 denotes a flat rectangular dustproof hood having a larger plane area than the workbench 1, and covers not only the workbench 1 but also the surrounding upper part thereof. The dust-proof hood 20 is formed on four sides by an L-shaped four-sided frame 21. Further, the four-sided frame 21 is reinforced by the middle crosspiece 22 incorporated in the double girder. Reference numeral 23 denotes a ceiling plate attached to the dustproof hood 20, which may be a thin steel plate or a resin plate. In this case, the ceiling plate 23 does not necessarily need to be transparent. This dustproof hood 20
Is hung on the building through hooks 4 at the four corners of the top surface. Also,
An appropriate number of germicidal lamps 5 are mounted on the lower surface of the ceiling plate 23.

F is a blowing means mounted on the dustproof hood 20, and K is a curtain mounted on the four-sided frame 21 so as to be movable left and right. A mainly nylon one is preferable, but it is not necessarily transparent. It doesn't need to.

Ka is an edge of the curtain K and exemplifies a place where a worker enters and leaves. Reference numeral 21a denotes a curtain rail mounted on the upper side of the four-sided frame 21 on the inner side of the dustproof hood, and 21b denotes a hanger roller that can roll inside the curtain rail 21a.
A plurality of upper ends of the curtain K are fixed to the hanger roller 21b. D indicates a work space around the work table 1 in the dustproof hood 20, and M indicates a position of a worker in the work space D.

In this embodiment, a worker can enter the work space D of the dustproof hood 20 to take food in and out while observing the food directly with the naked eye, not through the hood. The place where the food is cooled by the dustproof hood 20 is partitioned by a curtain K from another work place.

FIG. 8 shows a plan view of the fourth embodiment. In this example, a preparation room is additionally provided on one side of the work space D of the third embodiment. That is, the preparation chambers B and C are further extended to one side of the four-sided frame 21 so that the three-sided ceiling outer frame 21
Enclose with a and curtain K on the three sides of this overhang
Hang. In this example, the blowing means F also faces the partition chamber B, and a sterilizing spray can be included in the blowing air.

In the fourth embodiment, the worker first enters the preparation room B from the preparation room C, receives the sterilization and sterilization from the blowing means F, and then enters the dustproof hood 20. Therefore, it is possible to prevent the confusion of the air flow in the dustproof hood 20 and the carry-in of various bacteria due to the comings and goings of workers, which is extremely hygienic. Although the preparation chambers B and C are shown only on one side of the workbench 1 in the drawing, they may be provided on both sides.

As described above, according to the present invention, since the clean air is sent into the dustproof hood and the respective partition chambers surrounded by the curtains by the operation of the blowing means, the hood becomes slightly higher in pressure than the outside air and the air from the outside Does not flow in,
Therefore, there is no risk of miscellaneous bacteria being mixed in the food and it is extremely hygienic and safe.
