2. Description of the Related Art Frozen foods include those mainly intended to maintain freshness or frozen foods cooked and processed so as to save the consumer's hands. Recently, frozen foods have been widely distributed with the increase of imports and the change of social circumstances in the era of aging. Commonly used thawing methods include room temperature natural thawing or air thawing, water thawing, microwave thawing, and heat thawing, but the thawing method is selected by the type, size, shape, etc. of fresh or cooked products. .

[0003]

In the above-mentioned thawing method, there is a disadvantage that thawing means such as natural thawing at room temperature or natural thawing at low temperature requires a long time for thawing. Further, in microwave thawing or high-frequency heating thawing, although the thawing time is short, there is a drawback that the amount of dripping of the food is large and the quality of the food cannot be reduced. In order to solve the above-mentioned inconvenience, for example, a thawing device using a hot-air fan is designed to thaw from both upper and lower surfaces by forced convection heat transfer by hot air and heat conduction from an aluminum plate. However, when thawing with a hot air fan using air with poor heat transfer characteristics, the thawing speed of frozen food is slower than thawing by heat transfer from an aluminum plate with high thermal conductivity, and thawing is performed for a certain period of time. In this case, so-called uneven thawing occurs in which a difference occurs in the thawing state between the lower surface side and the upper surface side of the frozen food.
Therefore, if the thawing is performed on the lower surface side, the thawing on the upper surface side is insufficient, and conversely, the amount of drip generated on the lower surface side with respect to the upper surface side increases, and the quality of the frozen food deteriorates. There is a difficulty such as. On the other hand, for example,
A thawing apparatus as disclosed in Japanese Patent No. 278172 has been proposed. In addition to an aluminum plate driving mechanism, a temperature detecting element, and the like,
It is a complicated device provided with an upper heater of the electric heater.

Conventionally, for example, as shown in JP-B-48-25414, a metal such as aluminum having good thermal conductivity is provided at an appropriate interval inside an outer box formed of metal or synthetic resin in a box shape. An example in which an inner box is provided is known.
However, in such a configuration, although the bottom part can be thawed, the effect of the radiant heat from the top or side part is almost negligible because the heat ray wavelength from the heater through the inner box is in the near infrared region of 5 μm or less. Heating is mainly performed by the convection of the heated air in the thawing box, so that the thawing of the food to be frozen easily occurs and the thawing time is long, and the thawing can be performed properly depending on the size and weight of the food. However, there was a problem that it was affected. In addition, if the food is left as it is after thawing, the quality of the meat, especially fish meat, will change due to the high ambient temperature. There were difficulties. In order to solve these problems, it is necessary to provide a thawing control device as disclosed in Japanese Patent Application Laid-Open No. 4-187969. In addition, the frequency of use of frozen foods is extremely high, and thawing is to thaw foods as needed until it reaches the appropriate temperature. In addition, the apparatus is required for business use. For this reason, the apparatus is a complicated apparatus provided with apparatus control means and the like as disclosed in Japanese Patent Application Laid-Open No. 4-187969.

As described above, in order to always maintain an optimal heating capacity, for example, by using a heater to avoid applying too much heat or insufficient heating, the mechanism of the apparatus must be complicated, and There is a drawback such as food drip outflow and the like, and there is a demand for a defrosting means which can easily and quickly defrost in an emergency and can prevent food drip outflow.

[0007]

The inventor of the present invention disclosed in Japanese Patent Publication No. 5-88101 that a frozen food was rapidly thawed with a plate-like body such as a graphite-based compound having a large thermal diffusivity. Patent No. 2631 , besides a frozen food melting machine that prevents deterioration and prevents the drip from flowing out and shortens the thawing time
No. 259 proposes a continuous processing apparatus for thawing, refrigeration and preservation of frozen foods, etc., but in order to achieve the above object, the present invention appropriately responds to urgent requests by further shortening the thawing time. It can be quickly defrosted without the need for operating mechanisms such as switches and buttons without using heat, leaving the goodness of spontaneous thawing, preventing the loss of taste due to the outflow of meat juice (drip), deterioration and discoloration after thawing, We examined a quick thawing method that completely preserves the taste.

In the above thawing plate member, when a constant temperature is maintained for a long period of time, the behavior of the supercooled aqueous solution related to the precipitation of crystals and heat generation, that is, the place where crystals should originally be precipitated with a saturated aqueous solution are in a state of non-precipitation. Focusing on the control of the so-called supercooled liquid, for example, consider compounding compounding such as phosphoric acid-based composite crystallite crystals, addition of a crystal nucleating agent, supercooling regulator, etc. The temperature compensating material spacer which coexists is constituted, the spacer is abutted or placed on the thawing plate, and it is arranged in combination, and the thawing action more than the sum of these is greatly improved by the synergistic effect, and the thawing time is shortened. ,
That is, it was found that it was suitable for further rapid thawing. Based on this finding, the present inventor intends to solve the problems of the present invention as described above.

As the main component to be included or coexisted as the temperature compensating material spacer according to the present invention, it is appropriate to use, for example, a phosphoric acid complex crystallizing agent as a supercooled aqueous solution related to crystal precipitation and heat generation. It is. Further, with respect to the phosphoric acid-based composite crystallizing agent, the generation of crystals can be controlled by compounding or compounding, adding a crystal nucleating agent, or adjusting with a supercooling control agent or the like. In addition, even if the phosphoric acid-based composite crystallizing agent is leaked or exuded due to cracking or tearing of the bag due to frequent use, handling, etc., even if the bag is leaked or exuded, it is suitable as a food additive standard product. And safe. Therefore, it is preferable that the above-mentioned components are safe at least in handling frozen foods because they affect human bodies. Since the temperature compensating material spacer according to the present invention has a necessary and sufficient condition of a temperature compensating effect of generating heat as it is cooled, a thawing plate member, for example, the graphite compound or the graphite-based composite having a thawing function Further, those obtained by subjecting them to surface coating with a synthetic resin such as polyurethane resin, or metal materials such as aluminum, copper, silver, and iron, and those further subjected to surface coating with a synthetic resin, and those of silicon carbide When used in combination with a plate-like body such as a ceramic compound as described above, the thawing plate is hardly cooled, and the thawing power is further increased and maintained. Therefore, it does not require electricity or a heat source, can be quickly thawed by using the temperature of air without using heat, can prevent the drip outflow and discoloration, and can be quickly spontaneously thawed, which can leave the whole taste.

The temperature compensating material spacer may be in the form of a bag made of a synthetic resin material or a box-shaped material made of a heat conductive metal material. A temperature compensating material is included in the bag of the synthetic resin material provided, or a partition is provided to allow the compensating material to coexist, and the periphery of the bag is sealed or sewn. It is easy to install as a combination with
Appropriately, it is possible to simplify the apparatus composed of a combination with a thawing plate and make the apparatus compact.

Further, the temperature compensating material spacer of the present invention comprises:
For example, it has a defrosting function, and the bar-shaped members are connected side by side in the longitudinal direction, and each bar-shaped member is rotatably connected so as to be bent or foldable, and placed or wound on the food to be thawed. It is also used as a combination with a foldable and active thawing plate that can be formed, further enabling rapid thawing of frozen foods. Further, the temperature compensating material spacer of the present invention can be used as a cooling material in connection with its own function, and is configured under the thawing plate. This is effective for maintaining the freshness of the food.

[0012]

The thawing temperature compensating material spacer of the present invention generates heat as it is cooled, making it difficult to cool the thawing plate, further increasing and maintaining the thawing force, and in combination with the thawing member, the amount of heat transfer per unit time The thawing progresses rapidly because of the remarkable increase, and it works so as to exert a synergistic effect more than the sum of these. Also, when installed and interposed in combination with a decompression plate made of metal or the like with good thermal conductivity, it does not require electricity or a heat source, can be quickly defrosted without using heat, and has a simple mechanism and good spontaneous defrosting. It is sanitary without giving time for germs to thrive even after thawing, and by shortening the thawing time, it prevents the appearance change and discoloration of the food to be thawed. Work not to cause.

FIG. 1 is an explanatory side sectional view showing an embodiment of the present invention. In FIG. 1, in the temperature compensating material spacer for thawing according to the present invention, the spacer main body 1 includes a temperature compensating material 5.
6 made of a synthetic resin material in which a peripheral portion 7 is sealed.
And is disposed below the thawing plate 2 made of a graphite-based compound plate. 9 is a leg, and 10 is a case. On the upper surface of the thawing plate 2, for example, beef steak meat 3 as a food to be thawed is placed. In addition, the configuration shows a configuration in which the food mackerel 4 to be thawed wound by the foldable active thawing plate 8 is placed on the upper surface of the thawing plate 2 and installed as a combination of the thawing plate 2 and the spacer body 1.

Next, on the lower surface side of the thawing plate 2, manufactured by Precision Assen, model number Z-4, a bag containing a temperature compensating material 6 containing a phosphoric acid-based composite crystallite crystal (calcium phosphate composite crystallizing agent) as a main component. When the body 8 is placed, and a bag body containing a heat storage material mainly containing an ethylene glycol solid solution,
The case of placing on the lower surface side of the thawing plate 2 was compared with the melting time of the ice block, the temperature drop, the operability, and the effect on the melting of ice (comparison of melting time). Test conditions: Room temperature 23 ° C Ice block temperature -9.5 ° C Ice block weight 315g Initial thawing plate temperature 23.0 ° C Initial temperature compensating material temperature 21.3 ° C Thawing plate size 22.3 × 30.5 × 1.0cm When comparing the configuration in which a thawing plate and a temperature compensating material spacer are installed in combination with the configuration in which a thawing plate and a commercially available thermal storage material bag are also installed, heat storage mainly composed of starch-based or ethylene glycol solid solution, etc. Since the material does not have the ability to generate heat by itself, the thawing effect lasts longer than air or water-filled bags, but does not show any significant effect. In contrast, the temperature compensating material spacer of the present invention utilizes the heat of dissolution reaction during crystal precipitation,
It can be used repeatedly at room temperature, and the duration of the effect is much longer. Therefore, in the combination of the temperature compensating material spacer and the thawing plate according to the present invention, the temperature of the thawing plate decreases slowly, while the combination of the heat storage material and the thawing plate speeds up. Also, comparing the melting time (however, in the case of melting time for a large amount of ice blocks),
Assuming that the thawing plate for air contact is 1, the value is 0.78 in combination with the heat storage material, and 0.41 in combination with the temperature compensating material spacer. In addition, in terms of operability, in the configuration of the combination with the heat storage material, the operation is performed after heating, but in the configuration of the combination of the temperature compensator spacer and the thawing plate in the present invention, the heating is unnecessary. is there. Furthermore, as for the melting time, the melting time in air is about 90 minutes, whereas the combination of the thawing plate and the heat storage material is about 70 minutes, whereas the combination of the temperature compensating material spacer and the thawing plate of the present invention is about 70 minutes. 37 minutes. Thus, by installing the temperature compensating material spacer for thawing of the present invention in combination with the thawing plate, it can be quickly thawed at room temperature without using heat, preventing the drip from flowing out, leaving the goodness of natural thawing and degrading freshness. It is sanitary without giving time for breeding of various bacteria, and can be quickly thawed in a shorter time than the conventional thawing plate itself. Although one embodiment of the present invention has been described, the present invention is not limited to the above-described embodiment, and includes any design changes or the like within a range not departing from the gist of the present invention.

[0015]

When the temperature compensating material spacer for thawing of the present invention is used in combination with an thawing plate or an active thawing plate wound with the food to be thawed, the spacer generates heat as it is cooled, The thawing plate is hard to cool and the thawing power is further increased and sustained, the thawing time can be significantly shortened, no electricity or heat source is required, and after thawing there is no hygiene time for germs to grow and it is hygienic and the juice flows out And prevent deterioration.
In addition, the mechanism for assembling with the thawing plate is simple, and the bag body containing the temperature compensating material is slightly deformed so that it can be easily fitted and brought into contact with the thawing plate. This has the effect that the thawing can be reliably performed.
