Abstract

PURPOSE:To provide the title equipment capable of thawing frozen foods in high efficiency in a short time, made up of a heating medium-packed chamber, a heat-absorbing section and a heat-transferring section with tape needles. CONSTITUTION:The objective thawing equipment made up of (A) a heating medium-packed chamber 5 with many fins 6, (B) a heat-absorbing section 2, and (C) a heat-transferring section 3 with many fins 4 to transfer the heat from the section B to frozen foods 9 (e.g. consisting of aluminum). The needle 4 are stuck into the frozen foods 9 and a heating medium of <=37 deg.C is fed through an inlet 7 into the chamber 5; then the fins 6 absorb the heat of the medium and transfer it to the needles 4, thus resulting in thawing the frozen foods 9 from the interior.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a defroster used to defrost frozen foods such as meat.

[Conventional technology] Conventionally, frozen foods such as meat and fish have been defrosted using natural thawing methods, in which they are exposed to air or immersed in water to thaw them naturally, or forced thawing in a microwave oven, etc. If a forced thawing method was used, or if natural thawing was used, the thawing time is generally from several tens of minutes to several tens of hours, depending on the size of the food, as the food is gradually thawed from the surface. Not only does it take too long to defrost, but the quality tends to deteriorate if exposed to air or water for a long period of time.Also, if you force defrost it in a microwave, you will need thawing equipment. Another drawback was that the quality of the food could easily change due to heat.

[Problems to be Solved by the Invention] An object of the present invention is to provide a thawing device that can efficiently thaw frozen foods within a short period of time.

[Means for Solving the Problems] In order to solve the above problems, the thawing device of the present invention has a heat absorbing part that absorbs heat from a heat medium such as a liquid or gas, and a heat absorbing part that absorbs heat from the heat absorbing part by inserting it into frozen food. The heat transfer part includes a prick that transmits heat to the inside of the frozen food, and the heat absorption part is characterized in that a filling chamber for filling a heat medium is formed.

[Function] When defrosting frozen food, insert the needle of the defroster into the frozen food and supply a heat medium to the filling chamber.

As a result, the heat of the heat medium is absorbed by the endothermic part, and this heat is transmitted to the inside of the frozen food through the needle, so the frozen food is thawed not only from the surface but also from the inside, and the whole food is thawed in an extremely short time. will be done. Moreover, among foods,
Since it is thawed evenly from the outside, there is no chance of uneven thawing or deterioration of quality.

[Embodiments] Hereinafter, embodiments of the present invention will be described in detail based on the drawings.

FIG. 1 shows an embodiment of a decompressor according to the present invention.
This defroster 1 includes an endothermic part 2 that absorbs heat from a heat medium such as liquid or gas, and a plurality of needles 4 that transmit heat from the endothermic part 2 to the inside of the frozen food by piercing the frozen food. These are made of a metal with excellent thermal conductivity, such as copper, copper alloy, aluminum, aluminum alloy, etc.

As is clear from FIG. 142, a filling chamber 5 for filling the heat medium is formed in the heat absorption section 2, and the filling chamber 5 is in contact with the filled heat medium to generate heat. A plurality of fins 6 are provided to absorb the water. The fins 8 also serve as a baffle plate, and the inside of the filling chamber 5 is partitioned into a zigzag-shaped flow path by these fins S, and the lower end of the flow path is an inlet for the heat medium, and the outlet is at the other end. 8 is provided. The filling chamber 5 can be opened and closed.

When defrosting frozen food using the defroster l having the above configuration, as shown in FIG.
is inserted into the frozen food 8, and a heat medium is supplied to the filling chamber 5 through the input lower. In this case, the heat medium may be allowed to flow continuously with the outlet 8 open, or the heat medium may be confined within the filling chamber 5 by sealing the outlet 8. Also, the temperature of the heat medium supplied may be The higher the temperature is, the better the thawing efficiency will be, but if the temperature is higher than 37°C, protein denaturation is likely to occur, so it is desirable to adjust the temperature to 37°C or lower.

When the heat medium is thus supplied to the filling chamber 5, the heat of the heat medium is absorbed by the fins 6, and this heat is transmitted to the inside of the frozen food 8 through the prick 4 in the heat transfer section 3, so that the frozen food 8 The food is thawed not only from the surface but also from the inside, meaning that the whole thing is thawed in an extremely short time. Moreover, since the inside and outside of the food are thawed evenly and almost simultaneously, there is no uneven thawing or dripping, and no deterioration of the quality of the meat.

Note that a plurality of the defrosters 1 may be used in combination depending on the size of the frozen food 5 and the like.

The decompressor of the present invention can have various configurations other than those described above, some examples of which are shown below.

The defroster 21 of the s2 embodiment shown in FIGS. 4 and 5 includes a heat absorbing section 22 having a cylindrical filling chamber 25,
The inside of the filling chamber 25 is partitioned in a zigzag shape by fins 26 which also serve as baffles. Note that the inside of the filling chamber 25 can also be partitioned into a spiral shape by fins 26.

In the defroster 31 of the third embodiment shown in FIG. 6, a heat transfer section 33 is formed by providing a plurality of needles 34 in a matrix on the bottom surface of a filling chamber 35 in a heat absorption section 32.

Note that although the filling chamber in the defroster of each of the above embodiments has a sealed structure, the filling chamber may be oven-shaped with an open top surface, or fins may be provided inside the filling chamber. Instead of this configuration, the fins may be hollow and the inside of the fins may be used as a filling chamber.

[Effects of the Invention] According to the present invention having the above configuration, a filling chamber is provided in the heat absorption part, and the heat of the heat medium filled in the filling chamber is transmitted to the inside of the frozen food through the prick, so that the frozen food is Since the food can be thawed quickly from the inside, and evenly and simultaneously inside and outside, there will be no uneven thawing, dripping, or deterioration of quality.

Furthermore, since the heat absorption rate is better than when thawing is done by absorbing heat from the atmosphere, the thawing efficiency can be further increased.
