Liquid cooling foods freezer

Abstract

The object of invention is to provide a liquid-cooled food refrigerator, efficiently uniformly cooling antifreeze liquid bath in an antifreeze liquid tank by a modularized piping unit, simplifying assembling and facilitating expansion. This liquid-cooled food refrigerator includes the antifreeze liquid tank 3; a stirring means; a heat exchange piping means; a cooling force-feed means 1 for supplying a refrigerant to the heat exchange piping means; and a carrying means for dipping foot to be refrigerated in an antifreeze liquid bath in the antifreeze liquid tank 3. In the heat exchange piping means, the piping unit 10 is formed by modularizing at least two vertical pipe parts 11, at least two meandering pipe parts 12, an inlet manifold port 13 and an outlet manifold port 14, two or more units are sequentially arranged along the wall surface extending over the whole periphery of the side wall of the antifreeze liquid tank 3, and connected in parallel to the manifold means 15, 16, 17, 18 on the outward side and on the return side, and the manifold means on the outward side and on the return side are connected to the output side and the feedback side of the cooling force-feed means (the so-called refrigerator ) 1.

Description

technical field [0001] The present invention relates to a liquid-cooled food freezing device, which has an antifreeze tank mechanism capable of containing an antifreeze solution (such as ethanol + water as the main component) generally called "coolant", and agitates the antifreeze solution tank mechanism. The stirring mechanism of the antifreeze liquid, the heat exchange piping mechanism for the antifreeze liquid (antifreeze liquid bath) in the antifreeze liquid tank mechanism to cool the antifreeze liquid (antifreeze liquid bath) along the side wall of the antifreeze liquid tank mechanism, and the heat exchange piping mechanism provided Refrigerant cooling and pressure feeding mechanism, transport mechanism for immersing the food to be frozen in the antifreeze of the above-mentioned antifreeze tank directly or after packaging. Background technique [0002] Different from the ordinary air-conditioning freezing type that freezes food by cooling the air enclosed in the freezin...

Problems solved by technology

[0004] However, in conventional liquid-cooled food freezers, as shown in Figure 4 and Figure 7 of Patent Document 1, only the heat exchange piping mechanism is hung around the three side walls of the rectangular antifreeze tank, and the stirring mechanism is arranged along one side wall. The side wall of the side wall is not equipped with a heat exchange piping mechanism

Therefore, there is the disadvantage that it takes time to bring the antifreeze in the antifreeze tank to a uniform cooling temperature.

[0005] In addition, the piping along each wall surface is custom-made according to the size of the antifreeze tank. By combining straight pipes, U-shaped pipes and elbow-shaped pipes, a single serpentine pipe is formed as shown in Fig. 7 of Patent Document 1. The cooling solenoids 4 and 3 of the heat exchange piping mechanism on the two side walls are connected in series, and the other side wall is provided with a cooling solenoid 5 of another system. Therefore, the piping work is complicated and the assembly of the device is time-consuming and laborious. The main reason for the increase in cost

[0006] In particular, when manufacturing a large-scale liquid-cooled food freezer, it took time to bring the antifreeze in the antifreeze tank to a uniform cooling temperature in the conventional structure, and the assembly was also complicated.
