That is, while filling of drinking water is stopped, the entire amount of drinking water is heated and sterilized again.
Energy such as electric power required for heating was large. Moreover, since drinking water is heat-sterilized many times, there is a possibility that the quality of drinking water may be degraded.

び品質劣化が抑制される。According to such a configuration, the liquid such as drinking water filled in the container is heat-sterilized by the heat sterilizer,
It is introduced into the filling valve via the introduction passage. Then, when the high-temperature liquid is filled, the container is filled with the high-temperature liquid introduced into the filling valve. On the other hand, when the filling of the high-temperature liquid is stopped, a predetermined amount of the high-temperature liquid introduced into the filling valve is returned to the introduction passage via the return passage. At this time, the high-temperature liquid refluxed to the introduction passage is reheated by the reheating device.
For this reason, even when the high-temperature liquid is not being filled, the high-temperature liquid is always filled up to the tip of the filling valve. The temperature of the hot liquid after sterilization is prevented from lowering. Also, to prevent the temperature of the high-temperature liquid from dropping,
Minimizing the amount of high-temperature liquid to be reheated suppresses energy consumption and quality deterioration.

０％であれば十分であった。According to this configuration, even when the high-temperature drinking water is not being filled, a predetermined amount of the high-temperature drinking water introduced into the filling valve 20 is circulated while being reheated. For this reason, the hot drinking water is always filled up to the tip of the filling valve 20. For example, even if the hot drinking water filling line is stopped for a long time due to a failure, the temperature of the hot drinking water after heat sterilization is prevented from lowering. be able to. Also,
Energy consumption and quality deterioration can be suppressed by minimizing the amount of drinking water to be reheated in order to prevent a decrease in the temperature of the high-temperature drinking water. According to experiments, the amount of drinking water to be reheated is 3% to 2% of hot drinking water supplied to the filling valve 20.
0% was sufficient.

制することができる。As described above, according to the first aspect of the present invention, even when the high-temperature liquid is not filled, the high-temperature liquid is always filled up to the tip of the filling valve. It is possible to prevent a decrease in liquid temperature after heat sterilization. That is, regardless of the length of the filling stop time, even if the supply of the container is intermittent, it can be ensured that the filling liquid temperature does not decrease. Further, by minimizing the amount of the high-temperature liquid to be reheated, energy consumption and quality deterioration can be suppressed.

According to the third aspect of the invention, oxidation of the high-temperature liquid by air is prevented, and deterioration of the liquid quality can be suppressed. According to the fourth aspect of the invention, at the time of starting the filling of the high-temperature liquid, the high-temperature liquid in the gas-liquid pipe falls into the container, so that the air existing in the container can be discharged in a short time, and the filling time can be reduced. Can be effectively shortened.
