The cooling tank 1 is a vertical container having a stepped shape, and includes a body portion 31, a mouth portion 32 having a larger diameter than the body portion 31, and a step portion 33 connecting the body portion 31 and the mouth portion 32. Prepare. The evaporating tube 2 is spirally wound around the body 31 of the cooling tank in close contact with the helical shape.
0 allows the refrigerant to flow into the evaporating pipe 2 from the bottom side of the cooling tank 1. The side surface and the bottom surface of the cooling tank 1 including the outer peripheral portion of the spiral evaporation tube 2 are all covered with a heat insulating material 6.

１０の圧縮機１２へ戻る。Next, the operation of the above-described beverage cooler will be described by taking as an example a case where hot coffee liquid is cooled. When the high-temperature coffee liquid extracted from the hot coffee powder is poured into the receiving container 9, the high-temperature coffee liquid is cooled little by little through a large number of pores 17 provided near the periphery of the bottom of the receiving container 9. It is poured onto the step 33 of the tank, spreads out in a plane at the step 33, and flows down in a film form along the inner surface of the side wall of the body 31 of the cooling tank. When the temperature of the side wall of the body part 31 rises due to the injection of the high-temperature coffee liquid, and this is detected by the temperature detector 3, the thermostat 5 is operated and the operation of the compression refrigerator 10 is started. As a result, the refrigerant vapor flows into the evaporating pipe 2 from the lower end side (bottom side of the cooling tank 1), rises while cooling the side wall of the body 31 of the cooling tank, and evaporates and the refrigerant vapor that has lost the cooling capacity becomes It returns to the compressor 12 of the compression refrigerator 10 from the upper end side of the evaporation pipe 2 (the upper end side of the body 31).

びサーモスタット５により所定の温度に維持される。The coffee liquid that flows down in a film form on the inner surface of the side wall of the body 31 of the cooling tank is rapidly cooled by contact with the side wall cooled by the evaporating pipe 2, and then accumulates at the bottom of the cooling tank 1. The coffee liquid in the cooling tank 1 is further cooled through the wall surface of the cooling tank 1 and is maintained at a predetermined temperature by the temperature detector 3 and the thermostat 5.

は、余り冷却されない。When attention is paid to a state in which the high-temperature coffee liquid injected into the cooling tank 1 is cooled while flowing down the wall surface of the cooling tank 1, the refrigerant flowing into the evaporating pipe 2 from the lower end side evaporates. While the cooling tank 1 is gradually cooled from the lower side toward the upper side, the cooling tank 1 is heated by heat exchange with the high-temperature coffee liquid flowing down in a film form before reaching the middle height of the cooling tank 1. And the side wall of the cooling tank 1 located at a height higher than that remains without being cooled. As a result, the coffee liquid flowing down the wall surface of the cooling tank 1 is not cooled much in the upper half of the cooling tank 1.

れることになる。As the level of the coffee liquid in the cooling tank 1 gradually rises, the distance that the coffee liquid flowing down on the wall contacts the cooled portion of the wall of the cooling tank 1 becomes shorter. Therefore, cooling becomes difficult. In this manner, when the liquid level of the coffee liquid in the cooling tank 1 exceeds the level at which the refrigerant in the evaporating pipe 2 has finished evaporating, the coffee liquid flowing down the wall surface is not cooled, and is kept at a high temperature without cooling. It will be poured over the coffee liquid pooled inside.

Such a temperature difference is gradually alleviated by convection in the cooling tank 1 and cooling from the wall surface, but it takes a long time until the whole is cooled to a uniform temperature. By the way, in order to maintain good quality such as aroma and taste of a beverage, it is generally important to cool the beverage from a high temperature state in a short time. If there is a temperature difference, it takes a long time for the beverage poured into the upper layer to cool, and for example, oxidation or deterioration of iced coffee or the like is promoted, and good quality cannot be obtained. is there.

率的に冷却されて、所定の温度に維持される。When the injection of the high-temperature beverage into the cooling tank is completed, the temperature of the step portion of the cooling tank gradually decreases, which is detected by the temperature detector, the four-way valve of the refrigerant circulation path is switched, and the refrigerant is discharged at the lower end. From the side into the evaporator tube.
Thereby, the beverage in the cooling tank is efficiently cooled from the surrounding wall surface and is maintained at a predetermined temperature.

It starts to flow from the upper end side (upper end of the body 31 of the cooling tank) through the expander 14 and the electromagnetic four-way valve 11, and evaporates the side wall of the body 31 of the cooling tank from top to bottom while evaporating. After cooling, it becomes a gas and returns to the compressor 12 from the lower end of the evaporating pipe 2 via the electromagnetic four-way valve 11. Thereby, the beverage that flows down in a film form on the inner surface of the side wall of the body 31 is
While flowing through the cooled part on the upper part of the side wall of the body part 31, it is rapidly cooled and accumulates at the bottom of the cooling tank 1.

なお、受け容器９の細孔１７の径及び数を変えることに
より、飲料の急冷の速度を調整することができる。Since the refrigerant in the evaporating pipe 2 exchanges heat with the high-temperature beverage at the upper part of the side wall of the body 31, the evaporation of the refrigerant is completed at the upper part of the side wall, and the refrigerant is almost cooled in a region below the upper part. Does not contribute. The high-temperature beverage injected from the receiving container 9 is cooled under the same conditions while flowing on the upper wall of the body 31, so that the beverage 21 stored at the bottom of the cooling tank 1 is cooled.
Is almost the same temperature from the upper layer portion to the lower layer portion.
The speed of the quenching of the beverage can be adjusted by changing the diameter and the number of the pores 17 of the receiving container 9.

The excitation of 1a is released, and the electromagnetic four-way valve 11 is switched to the refrigerant circulation path shown in FIG. Although the contact 8a of the temperature switch is opened, the temperature of the beverage 21 stored in the cooling tank 1 is already detected by the other temperature detector 3 through the side wall 31 of the body, and the contact 5a of the thermostat is detected.
Is closed, the energization of the motor 12a is continued, and the operation of the compressor 12 is continued.

As shown in (b), the refrigerant flows in from the lower end side of the evaporating pipe 2 (the bottom side of the cooling tank 1), cools the body 31 of the cooling tank from the lower part to the upper part, and drinks the beverage in the cooling tank 1. 2
1 is further cooled. In the course of this cooling, the temperature of the beverage 21 in the cooling tank 1, which was initially substantially uniform, temporarily differs between the upper and lower portions, and the lower portion is slightly lower,
When the whole is cooled to a certain temperature or less, the evaporation amount of the refrigerant in the lower part of the evaporating pipe 2 is reduced, and the evaporation region of the refrigerant is expanded to a region equal to or higher than the liquid level of the beverage 21.
The upper layer is also cooled via the side walls, and as a result, the temperature difference between the upper and lower portions is reduced again, and the temperature becomes substantially uniform over time. Based on the correlation between the temperature of the beverage 21 in the cooling tank 1 and the temperature transmitted to the temperature detector 3 via the side wall of the body 31, the thermostat 5 is set so as to correspond to a predetermined beverage temperature. When the temperature of the beverage 21 falls below a predetermined temperature, the thermostat contact 5a opens and the compressor 12 stops.
