Abstract
The present invention discloses a temperature controllable high temperature sterilization system for an air-tight room. A multilayer plate-fin heat exchanger outside which a heat insulating layer is coated and a spiral high temperature sterilizer are arranged on a bracket. Countercurrent heat exchange is adopted between layers. A cold air outlet of the other end of a last layer plate-fin heat exchanger is accessed into an inlet of cold air to be sterilized of the spiral high temperature sterilizer. A hot air inlet of the other end of the last layer plate-fin heat exchanger is communicated with an outlet of hot air which is sterilized of the spiral high temperature sterilizer. After the cold air is gradually exchanged in a heat mode, the temperature of the cold air gradually rises until the cold air enters a high temperature sterilization region. After the cold air is sterilized, the heat energy of the cold air is renewedly transferred to the side of the cold air, the cold air is gradually cooled until the cold air reaches a normal temperature to be discharged. The temperature differences of the inlets and the outlets of the cold air and the hot air are under 3 DEG C. Compared with a traditional high temperature sterilization method, the present invention has the advantages of low energy loss, high efficiency, no side effect on a human body and bacteria killing rate up to 100 %.
