[Industrial applications]

 The present invention relates to a cooling mat mounted on a sake storage tank, and in another aspect, to a sake storage tank mounted with a cooling mat.

[0002]

[Prior art]

 Brewing of sake is performed in the cold season, and when fermentation is completed, sake is subjected to the required processing such as filtration using a filter, then transferred to a storage tank and stored until shipment. . The storage period may range from several days to several months or more, and in some cases, several years, depending on the sales situation of the sake or until the desired quality of sake is obtained. It has been suggested that sake should be stored at a temperature as low as possible and in an environment with little temperature change. In the days when air-conditioning equipment was not well developed, it was common to build a warehouse, thicken walls to enhance the heat insulation effect, and install a storage tank in it to achieve the above objectives. It was

[0003] In recent years, with the increase in the production volume of high-grade maps represented by Ginjo liquor and raw liquor, these high-grade liquors are maintained at a temperature lower than room temperature, for example, a low temperature of 0-10 ° C to maintain and maintain the quality of sake. Storage methods have been widely adopted. As a cooling method, as shown in FIG. 1, the side wall of the storage tank has a double structure (5), a water channel (2) is provided, and a refrigerant is circulated therein to cool the sake. As shown, a flexible tube (6) is closely wrapped around the side wall of the storage tank, and water is circulated through the water channel (2) in the tube to cool the sake, or as shown in FIG. In many cases, a large number of water channels (2) are provided in a rubber plate, which are brought into close contact with the side walls of a storage tank, and a refrigerant is circulated through the water channels (2) to cool sake. By the way, storage tanks with sizes ranging from several hundreds of liters to over 100,000 liters are used, and various capacities are selected depending on the size of the brewery and the sales volume of products.

[Problems to be solved by the device]

 When storing sake, it is best to infuse it to near the top of the storage tank [eg, liquid level (8a) in Fig. 4] and minimize the contact area with air. Mandatory to hold. On the other hand, the currently adopted cooling methods are all cooling from the side wall of the storage tank, as shown in FIGS. Therefore, there is a considerable amount of sake (9) between the upper level [eg, Fig. 4 (8b)] and the full injection level [if Fig. 4 (8a)] of the cooling device provided on the side wall of the storage tank. Exists. The cooling effect of the cooling device (5) provided on the side wall of the storage tank having such a structure is mainly due to natural convection of sake, so that the sake (9) above the upper liquid level (8b) of the cooling device has no effect on the sake (9). The cooling effect is difficult to reach. Therefore, if there is invasion heat from the outside air, the sake (9) in this portion will continue to stay there while being warmed up.

When the sake tank is fully filled with sake, depending on the product, in order to sterilize the sake itself and the tank, the sake sake heated to around 65 ° C. is sent to the tank and is filled as described above (burning). After that, we want to cool this sake to the desired storage temperature in the shortest possible time. The cooling device is used for this cooling as well, but in the same manner as above, the sake (9) stored between the liquid levels (8a) and (8b) is significantly delayed in cooling and deteriorates in sake quality. Happens.

It is obvious that these problems can be solved by providing a cooling device similar to the side wall on the top plate portion of the storage tank, but in many storage tanks for high-grade sake, the top plate has an arm-like curved structure. In many cases, the provision of the cooling device as shown in FIGS. 1 to 3 is not adopted because of difficulty in machining and restrictions in cost. In order to stably produce high-quality sake, it has been earnestly desired to develop the cooling device for the top plate. The present invention has solved such a demand with a simple device.

[0007]

[Means for Solving the Problems]

 In order to solve the above problems, the present invention provides an outlet and an inlet for the refrigerant (hereinafter referred to as a cooling mat) in a flexible bag that does not leak water, and places it on the top plate of the storage tank. It is a device that cools the sake (9) remaining in the upper part of the storage tank through a refrigerant.

[0008]

[Action]

 Since the cooling mat of this invention is made of a flexible material, even if the storage tank top plate has a curved surface, the cooling mat fits well to the top plate and efficiently transfers the heat of the top plate to the refrigerant, thereby Can be cooled efficiently. When the top plate is cooled, the sake that is in contact with the top plate is cooled. When the sake that is in contact with the top plate is cooled, the cooled sake begins to settle due to convection, the warmer sake in the lower layer rises, contacts the top plate, and is cooled by the top plate. By this action, the sake that stays at a position higher than the upper edge of the side wall cooler is also cooled, so that the sake existing in the upper part of the storage tank is also cooled to an appropriate temperature and maintained at that temperature.

【Example】

 Although the embodiments of the invention are illustrated by showing the embodiments, the invention is not limited by the following embodiments. Example 1 FIG. 5 shows a circular cooling mat (10) according to the present invention, which is a 0.4 mm-thick sheet made of nylon fiber as a base material and laminated on both sides with polyvinyl chloride resin. . The two sheets were thermocompression bonded and molded into the shape shown in FIG. The cooling mat (10) is provided with a refrigerant inlet (3) and a refrigerant outlet (4). Depending on the size of the cooling mat (10), the flow of the refrigerant is regulated to improve the cooling efficiency. Thus, the partition wall (11) is provided and the water channel (2) is formed.

FIG. 6 shows a cylindrical rigid storage tank (1), and the top plate is composed of a bowl-shaped top plate (12). A cooling mat (10) is placed on top of it. When the cooling medium is passed through the cooling medium inlet (3) to the cooling mat (10), the sake (9) located above the upper liquid level (8b) of the cooling device (5) on the side wall is cooled by the cooling mat (10). To be cooled. Since the cooling mat (10) has a flexible material and structure, it deforms along the shape of the ceiling plate due to its own weight and the weight of the refrigerant in the water channel (2), and adheres to it to assist heat transfer.

Embodiment 2 FIG. 7 shows a rectangular cooling mat (10), and the material, manufacturing method and configuration are the same as in Embodiment 1. FIG. 8 shows a cubical storage tank (1) whose top plate has a structure similar to a gable roof. The cooling mat (10) is installed on the upper surface thereof. When the refrigerant is passed through the refrigerant inlet (3) through the cooling mat, the sake (9) located above the upper liquid level (8b) of the side wall cooling device (5) is cooled by the cooling mat (10). It

[Effect of device]

 The present invention is constructed with a simple structure, lightweight and flexible material. Therefore, the installation work of this cooling mat does not require specialized knowledge, special tools or equipment, and can be easily installed and removed. For the same reason as above, there are many existing sake tanks in Japan that can be cooled by simply placing the cooling mat on the top plate without performing any processing such as welding or drilling. become. In the recent market trend where the production volume of high-grade liquor is increasing year by year, this cooling storage tank that enables cooling from the upper part of the storage tank enables stable production of higher quality sake. In order to do so, it can make a great contribution to the industry.
