この発明は、加熱容器内の被加熱物を、減圧熱媒蒸気に
より加熱するようにした熱媒式加熱装置に関するもので
ある。DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a heat medium type heating device that heats an object to be heated in a heating container using reduced pressure heat medium vapor.
物品、例えば、食品や薬品等を加熱する場合、被加熱物

入して加熱する手法が広く用いられている。When heating an article, such as food or medicine, the object to be heated is placed in a heating container, and steam, hot water adjusted to a predetermined temperature, hot water, etc. is introduced into the heating jacket provided in the heating container. Heating methods are widely used.
しかるに、加熱される物品（食品や薬品等）には、ある

難しかったり、所望温度までの昇温に時間がかかる等、
操作性。However, some items that are heated (foods, medicines, etc.) may suddenly change color or lose their fragrance or medicinal properties when heated, reducing their commercial value. In some cases, it must be carried out at a relatively low temperature, below the temperature at which deterioration occurs, but with conventional equipment, it is difficult to control the temperature, and it takes a long time to raise the temperature to the desired temperature.
Operability.

ケット内に温水（あるいは熱水）を導入する型式のもの
では、加熱容器への熱伝達が悪く、昇温に時間を要し、
また、温度調節も難しいといろいろ問題がある。In other words, in the case of a type that introduces steam into the heating jacket, the internal pressure of the heating jacket is higher than atmospheric pressure, so the saturated steam temperature is approximately 100°C or higher, and it is difficult to maintain the temperature of the heating container below this temperature. . On the other hand, with models that introduce hot water (or hot water) into the heating jacket, heat transfer to the heating container is poor, and it takes time to raise the temperature.
Also, it is difficult to control the temperature, which causes various problems.
そこで、近年では上記加熱ジャケット内に、大気圧以下
の蒸気（以下、減圧蒸気と称する）を導入する加熱方法

和蒸気温度を低くすることができて１００°Ｃ以下での
加熱が可能となり、温度調節も蒸気圧力を加減すること
により行えるため、上述のような変質し易い物品でも、
適切な温度で容易に加熱することができる。Therefore, in recent years, a heating method has been proposed in which steam at a pressure below atmospheric pressure (hereinafter referred to as reduced pressure steam) is introduced into the heating jacket. By using such reduced pressure steam, the saturated steam temperature can be lowered, making it possible to heat below 100°C, and the temperature can also be adjusted by adjusting the steam pressure, so it is easy to deteriorate as described above. Even in goods,
Can be easily heated to an appropriate temperature.

まう。However, the above equipment requires a pressure reducing valve to adjust the Φ steam from the steam generating equipment such as a boiler to a predetermined pressure, a vacuum pressure reducing valve, and a special pressure reducing valve to forcibly discharge condensate from inside the heating jacket under negative pressure. This requires a pump device with a complicated structure, and is also extremely expensive.
