Problems solved by technology

The method and device generally adopted is to obtain a higher temperature through the high-pressure saturated steam generated by heating the closed container, usually the internal pressure is above 1.05kg / cm2, and the temperature is above 120°C, but due to its internal pressure Very high is a pressure vessel, so there are certain safety hazards in general household use, and there are disadvantages of complicated operation

Embodiment Construction

[0015] Below in conjunction with a preferred embodiment and accompanying drawing thereof, the present invention will be further described,

[0016] See shown in accompanying drawing 1, method of the present invention is to change liquid water into common steam (about 100 ℃) with common method earlier, and common steam forms superheated steam (about 300 ℃) through secondary heating; The superheated steam is sprayed into the airtight container containing the tableware to be sterilized to be sterilized; the steam with lower temperature in the container is taken away in time, mixed with ordinary steam and reheated into superheated steam, and the cycle is repeated until the tableware to be sterilized is thoroughly sterilized .

[0017] As shown in accompanying drawing 2, the preferred embodiment of the device utilizing superheated steam sterilization of the present invention includes a cabinet body containing tableware to be sterilized, and a superheated steam circulation generatio...

Abstract

The present invention relates to a method for sterilization and disinfection by using superheated vapor and its equipment. Said method includes the following steps: a). secondly heating general vapor (about 100deg.C) to form superheated vapor (about 300deg.C); b). spraying the superheated vapour into closed container in which the tableware to be disinfected are placed to make disinfection; and c). pumping out the vapor whose temperature is lowered from said container, mixing said vapor with general vapor and further heating them to obtain superheated vapor to make repeated circulation until the tableware are completely disinfected. Said method can kill the harmful pathogenic bacteria of colibacillus and staphylococcus aureus, etc.

Description

Technical field: [0001] The invention relates to the technical field of tableware disinfection, in particular to a method and device for sterilization by superheated steam. Background technique: [0002] Because steam has the function of killing bacteria efficiently, high-pressure steam sterilization is the best sterilization method and the most widely used sterilization method at present. The method and device generally adopted is to obtain a higher temperature through the high-pressure saturated steam generated by heating the closed container, usually the internal pressure is above 1.05kg / cm2, and the temperature is above 120°C, but due to its internal pressure Very high is a pressure vessel, so there are certain safety hazards in general household use, and there are disadvantages of complicated operation. Invention content: [0003] The object of the present invention is to overcome the deficiencies of the prior art and provide a method and device for generating superh...
