液槽内を均一に加熱することができる。 With the above configuration, each liquid tank 21, 22, 23
The mechanism by which the internal temperature is controlled to increase in stages will be explained. The bottle conveyed from the left side in the figure by the endless chain 28 is heated at room temperature or through a preheating process at the time it is immersed in the first liquid tank 21, but it is warmer than the cleaning liquid in the first liquid tank 21. It is at a low temperature, and is heated during the process of passing through the cleaning liquid heated by the heat exchanger 33, and is discharged at a higher temperature than before being immersed in the first liquid tank 21. Next, considering the case where this container is immersed in a second liquid tank, each flash nozzle 34,
The washing liquid returned through 35 has the same temperature as it is heated by a single heat exchanger 33, but the bottles to be washed have the same temperature as they enter the first liquid tank 21. Since the temperature entering the second liquid tank 22 is higher than the temperature, the drop in liquid temperature due to heating the bottle is smaller in the second liquid tank 22. That is, the liquid temperature of the second liquid tank 22 is maintained at a higher value than that of the first liquid tank 21. Similarly, the second liquid tank 22
A certain temperature difference occurs between the cleaning liquid and the third liquid tank 23 due to the difference in temperature of the bottle being immersed, and as a result, the first, second, and third liquids Tank 2
1, 22, and 23 are set to higher liquid temperatures in stages according to their arrangement. As described above, in this embodiment, the cleaning liquid in multiple tanks is heated by one heat exchanger 33, so there is no need to provide a flow rate adjustment valve or a temperature sensor for each tank.
Furthermore, since the heat exchanger is provided outside the liquid tank, corrosion can be prevented and maintenance is easy. In addition, since the temperature difference of the tank liquid is set based on the temperature difference of the bottles sequentially immersed in each tank 21, 22, and 23, it is possible to obtain a gentle temperature gradient according to the load of each tank. can. On top of that,
Since the heated liquid is circulated within the tank via a flush circuit installed at the bottom of the tank, the tank liquid does not stagnate and the liquid temperature becomes uneven as in the conventional case, and the temperature inside each tank is kept uniform. Can be heated.

In this example, a flow rate adjustment valve 37 is provided in the flash circuit 34 of the first liquid tank 22, and by adjusting the amount of liquid returned to this tank 22, the tank temperature can be controlled to an arbitrary value. can do. Such a flow rate regulating valve can also be provided in the other liquid tanks 22, 23, and all liquid tanks 21, 22, 23
The tank temperature can be controlled more accurately if it is provided.

2 and 43 are arranged adjacent to each other, and a container B such as a bottle is conveyed above each of these liquid tanks. Each liquid tank 4
The liquids in 1, 42, and 43 are sucked by pumps 44, 45, and 46 provided respectively, and are pumped into a container B such as a bottle through nozzles 47, 48, and 49 provided at the top of each liquid tank. Supplied as a shower or spray. The liquid supplied to container B falls directly into each liquid tank 41, 42, 43 and is collected. In this way, the bottle B is heated or cooled through the first water sprinkling process P 1 , the second water sprinkling process P 2 , and the third water sprinkling process P 3 corresponding to each liquid tank. In the past riser shown in Fig. 3,
As in the case of the above embodiment, each tank 41, 42, 4
Tank liquid outlet 50, 51, 52 at the bottom of 3, respectively.
is provided, and the tank liquid is sucked from this outlet by a pump 53 and sent to a heat exchanger 54. The taken out liquid is heated here and then transferred to each liquid tank 41, 4.
It is refluxed to 2,43. The liquid temperature of the tank liquid to be refluxed is measured by a temperature sensor 5 provided in the third liquid tank 43.
5 is controlled by a flow rate regulating valve 56 operated by 5 .

In process P 2 , the first
In step P1, bottle B, which has reached a higher temperature than in step P1 , is further heated. As a result, even if the liquid temperatures in both liquid tanks 41 and 42 are the same before heating bottle B, the liquid temperature in each tank 41 and 42 after being sprayed on bottle B is
The temperature of the tank liquid recovered in the second tank is higher than that of the second tank, and similarly, the temperature of the third tank 43 is higher than that of the second tank 42. In this way, also in this embodiment, one heat exchanger 54 is provided outside the liquid tank, and this heats the tank liquid in all the liquid tanks, so that the same effect as in the above embodiment can be obtained. Obtainable.
