いる熱媒体中をチェーンコンベヤによって運ばれる缶詰
の移動速度との関係によって行なわれる。
In the above-mentioned conventional sterilizer, the heat exchange between the hot water or cooling water heat medium and the canned food is carried out by a chain conveyor that moves the canned food through the stationary heat medium stored in each tank. It is done through relationships.

即ち熱力学的には、缶詰の移動速度が速いほど、境膜係
数が太きくなシ熱交換が活発になる。
That is, from a thermodynamic point of view, the faster the moving speed of the canned food, the greater the film coefficient and the more active the heat exchange.

従って熱媒体の温度を一定とした場合に、短時間に昇温
殺菌と冷却を行なうにはチェーンコンベヤの搬送速度を
速くする必要がある。
Therefore, when the temperature of the heat medium is kept constant, it is necessary to increase the conveyance speed of the chain conveyor in order to perform heating sterilization and cooling in a short time.

中に所定時間滞留する必要がある。
The above heat exchange is between the heat medium and the canned food, but on the other hand, the temperature of the contents of the canned food can be raised and cooled by natural convection or cooling, since the canned food is stationary on a chain conveyor. It is heated or cooled by heat conduction. For this reason, it is necessary to stay in the heat medium for a predetermined time until the temperature of the contents of the can reaches a predetermined temperature.

このような理由により、昇温殺菌と冷却を短時間に行う

For these reasons, in order to perform temperature-programmed sterilization and cooling in a short time, it is necessary to increase the conveyance speed of the chain conveyor and increase the residence time of canned goods in the heat medium. However, there is a problem in that the length of the heating tank and cooling tank must be extremely long.

Alternatively, the amount of heating steam and cooling water may be increased to raise the temperature of the hot water and lower the temperature of the cooling water, but this will increase the amount of heat dissipated from the surface of the ice stored in the tank. , a large amount of thermal energy is consumed, which poses a problem from the viewpoint of energy saving.
