Problems solved by technology

Although if the flow rate of cooling water is increased or the temperature of cooling water is lowered, the cooling capacity can be improved. In addition to cooling efficiency, there is also the problem of further enlargement of water tanks, etc.
[0007] In addition, the above points are common problems not only for milk tanks, but also for cooling tanks that store liquids (drinks, etc.) at low temperatures while cooling.

Embodiment Construction

[0027] Next, one mode of implementation of the invention will be described using FIGS. 1 to 4 .

[0028]The cooling tank 1 shown in FIG. 1 is used for putting milk into the inside of the tank main body 10 and transporting it while storing it at about 0°C. It includes a tank body 10 as a container for putting milk, a supply device 20 for cooling the brine of the tank body 10 from the outside, and a refrigerator 30 for cooling the brine. In the cooler (evaporator) 34 of the refrigerator 30, brine is cooled to about -1° C., and the tank main body 10 is cooled from the outer wall surface by passing the brine. In addition, the tank main body 10 is naturally provided with a milk inlet or outlet, etc., and is used to store basic configurations such as milk or accessories.

[0029] In the cooling tank 1, it has the following characteristics:

[0030] The first feature is to facilitate transportation as a container loaded on a truck or ship, such as figure 2 As shown, each part of ...

Abstract

A tank is provided which can store, while cooling, drinks or other liquids, such as milk, having a storage temperature close to 0.degree. C. or below. A cooling tank (1) can be mounted on a truck or the like for transportation, while storing and cooling milk. It is characterized in that brine (antifreeze solution) which has a freezing point below 0.degree. C. is cooled in a cooling unit (34) and allowed to pass, without stagnation, along fluid passages in flow guide members (14, 18) installed on the wall surface of the tank body (10). The cooling unit (34) preferably has an evaporator in a heat pump type refrigerator (30) for example, which uses a refrigerant for cooling the brine. Since the brine with a freezing point below 0.degree. C. is used, a large-sized water tank for cooling becomes unnecessary, and further since the brine will flow without stagnation, the liquid inside the tank body can be effectively cooled.

Description

technical field [0001] The present invention relates to a cooling tank capable of storing (or further transporting) liquids, especially drinks such as milk (milk) whose storage temperature is close to or lower than 0°C while cooling them. Background technique [0002] In order to maintain the freshness of milk, the milk tank for storing milk is desirably provided with a cooling function. A milk tank having a cooling function is described in, for example, JP-A-7-8127. [0003] The milk tanks described in the gazette, such as Figure 5 As shown, it is constructed by connecting the tank main body 10', the water tank (ice storage device) 34', the refrigerator 30', etc. through pipes 21' and the like. That is, the structure is as follows: the evaporator 34a' of the refrigerant passing through the refrigerator 30' is installed in the water tank 34', and in the water tank 34', cooling water close to 0°C is produced, and it is installed in the tank main body 10' The inside of the ...
