Description

[Detailed description of the device]

[0001]

[Industrial applications]

 This invention relates to a thawing device used for thawing an object to be thawed such as frozen food.

[0002]

[Prior art and problems]

 For example, when a large amount of frozen foods such as frozen shrimp is thawed in a factory, the thawed product is left to stand in a multi-stage thaw shelf made of stainless steel plate and left in a room temperature room or refrigerator for natural thaw. The method of making was generally adopted.

However, the thawing apparatus using such a stainless steel plate has a drawback that the processing efficiency is low because thawing requires a long time.

Therefore, a large-sized microwave oven, an electron thawing method for thawing by radiating electrons to the water content of the object to be frozen while cooling the interior to about −10 ° C., a far infrared heater using a heater heat source Various thawing methods such as thermal thawing method, warm air type tunnel thawing method, batch type thawing method, electrostatic thawing method, sprinkling type thawing method using water temperature, agitating and thawing method in water, etc. have been proposed, and equipment for that has also been developed. Has been done.

However, since all of these use electric heat and water, the device has to be large and complicated, resulting in high cost. Moreover, regarding water use, a wastewater treatment facility was also required due to the problem of wastewater treatment of sewage, resulting in larger and more complicated equipment and higher costs.

The present invention has been made in view of such technical background, and an object thereof is to provide a decompressing device capable of efficiently decompressing with a simple configuration.

[0007]

[Means for Solving the Problems] In order to achieve the above object, the present invention intends to use a finned aluminum plate having good heat dissipation efficiency as a thawing shelf instead of a stainless steel plate, and further promotes defrosting. It has been devised for such purposes.

That is, according to the present invention, referring to the reference numerals of the drawings, a plurality of defrosting shelves (2) made up of finned aluminum heat sinks (21) are installed in the upper and lower parts of the apparatus body (1). The defrosting shelves (2) are tilted with respect to the horizontal plane while being arranged in multiple stages with the inner part (21b) facing down and the defrosted object storage space (3) being separated. The gist is a defrosting device characterized by.

[0009]

[Action]

 Due to the high heat conductivity of the aluminum radiator plate (21) that constitutes the thawing shelf (2) and the effect of expanding the heat transfer area due to the presence of the fins (21b), the conventional thawing shelf (2) is made of stainless steel. Thawing is promoted as compared with, and thawing efficiency is improved. Moreover, since the electronic thawing method, the far infrared heater thermal thawing method, etc. are not used, the configuration is simple. Further, since the thawing shelf (2) is inclined with respect to the horizontal plane, the water and drip generated as the thawing progresses naturally flow down along the upper surface of the thawing shelf (2).

[0010]

【Example】

 Next, an embodiment of the present invention will be described with reference to the drawings.

1 to 3, (1) is a defrosting apparatus main body, and the apparatus main body is long in the vertical and horizontal directions in which an L-shaped cross-section angle member is arranged and connected at a position corresponding to each side of a rectangular parallelepiped shape. It is composed of a box-shaped frame. The L-shaped angle member forming the apparatus main body (1) is preferably made of extruded material such as stainless steel, copper, and aluminum, which does not cause rust and is resistant to corrosion and hygienic.

A plurality of thawing shelves (2) are vertically arranged in a multi-tiered manner in a substantially horizontal state with a space (3) for accommodating a thawed product to be frozen in a hollow portion inside the apparatus body (1). There is. These defrosting shelves (2) are a pair of shelf brackets (4) consisting of L-shaped cross-sections welded and fixed to the front and rear columns (1a) (1b) on the left and right sides of the device body (1). (4) It is removably mounted on the upper and lower left and right edges thereof in a locked state.

The defrosting shelf (2) is composed of three finned aluminum heat sinks (21) which are long in the left-right direction and which are divided in the front-rear direction for easy attachment / detachment during cleaning and the like and easy handling. . As shown in FIG. 4, each finned aluminum heat sink (21) is formed with a number of parallel fins (21b) extending vertically on one surface of a flat base (21a) extending in the longitudinal direction of the base. In this embodiment, an extruded profile of aluminum (including its alloy) having a fin portion (21b) height of 30 to 40 mm and a fin pitch of 10 to 20 mm is used. Such a finned aluminum heat sink (21) is arranged on the shelf brackets (4) (4) with the base (21a) facing up and the fin (21b) facing down, as shown in FIG. ing.

The pair of left and right shelf brackets (4) and (4) for supporting the thawing shelf (2) are set so that the attachment heights to the apparatus body (1) are slightly different. As a result, the thawing shelves (2) are slightly inclined with respect to the horizontal plane in the left-right direction, that is, the length direction. Inclining the thawing shelf (2) in this way promotes the discharge of water, drip, etc. generated when the object to be defrosted (D) placed on the thawing shelf is thawed, and maintains a favorable hygiene control state. At the same time, this is to improve the drainage when washing the thaw shelf. The inclination angle θ (shown in FIG. 5) of the thawing shelf (2) is not particularly limited, but in order to prevent the thawing target (D) from sliding down and efficiently perform the above-described water discharge and the like, It is good to set it to about 2 to 5 degrees. In addition, when there is a risk that the object to be defrosted (D) may slip due to the inclination of the thawing shelf (2), the height of the side wall (4a) of the shelf receiving bracket (4) should be set higher than the height of the thawing shelf (2). It is also recommended that the sidewall be raised above the top of the thawing shelf so that it is higher than the top.

Four casters (5a) (5a) (5b) (5b) are attached to each of the left and right sides of the bottom surface of the apparatus body (1) to enable movement of the defrosting apparatus. ing. One of the left and right casters is a rotatable caster (5a), and the other is a fixed caster (5b), ensuring good operability of the thawing device.

In the thaw device according to the illustrated embodiment, the thaw target (D) is placed on each thaw shelf (2) and naturally thawed. Since the defrosting shelf (2) that comes in contact with the object to be defrosted (D) is made of aluminum, it has excellent heat transfer properties and very good heat dissipation efficiency, and the fins (21b) increase the heat dissipation area. Further excellent heat dissipation is exhibited.

Further, although water and drip are generated from the object to be thawed (D) upon thawing, since the thawing shelf (2) is inclined in the longitudinal direction, it follows along the inclined surface of the thawing shelf (2). Moisture and the like naturally flow down and are naturally discharged from the side end surface of the thawing shelf (2) to the outside of the device. Incidentally, in order to accelerate the discharge of such moisture from the defrosting shelf (2), one or a plurality of water collecting fine grooves may be provided in the length direction of the upper surface of the aluminum radiator plate (21).

When it is necessary to wash the thawing shelf (2) after the thawing is finished, the thawing shelf (2) may be removed from the shelf receiving metal fitting (4) and this can be performed. Since it is divided into three pieces in the direction (width direction), handling such as attachment / detachment and cleaning becomes easy.

In the above embodiment, the shelf receiving metal fittings (4) are attached to the left and right sides of the apparatus main body (1), and the lengthwise ends of the defrosting shelf (2) are supported by the metal fittings. However, the shelf receiving metal fittings (4) may be arranged on both sides in the front-rear direction to support both ends in the width direction of the defrosting shelf (2).

[Effect of the device]

 According to the above-mentioned invention, according to the above, a plurality of thawing shelves consisting of aluminum heat sinks with fins are provided in the vertical direction inside the main body of the device, with the fins on the lower side, and the thawing object storage spaces separated. Because the thawing racks are arranged in multiple stages, the high heat conductivity of the aluminum radiator plates that make up the thawing rack and the effect of expanding the heat transfer area due to the presence of the fins make the thawing rack thawed compared to the conventional product made of stainless steel. The efficiency can be significantly improved and the thawing time can be shortened. Moreover, since the electronic thawing method, the far infrared heater thermal thawing method, and the like are not used, the configuration can be simplified.

By the way, when a 2 kg packed rose block freezing broiler (size of about 4 cm × 25 cm × 30 cm) was naturally thawed at an ambient temperature of 18 ° C. using a conventional thaw device using a stainless steel thaw shelf, − The time for thawing from 20 ° C to 0 ° C was 15 to 18 hours. On the other hand, when the freezing apparatus according to the present invention was used to perform natural freezing under the same conditions, the thawing time was 5 to 6 hours. Therefore, it was confirmed that the thaw time can be significantly shortened by the antifreezing apparatus according to the present invention.

Further, since the thawing shelf is tilted with respect to the horizontal plane, water and drip generated as thawing proceeds can naturally flow down along the upper surface of the thawing shelf, and the thawing device Can be naturally discharged to the outside. Therefore, it is possible to eliminate the inconvenience that water accumulates on the thawing shelf, which poses a sanitary problem and hinders thawing.
