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:
The present invention relates to the table-ware disinfection technical field, refer in particular to a kind of method and device that utilizes the superheated steam sterilizing.
Background technology:
Because steam has the function of efficient kill bacteria, so the high steam bactericidal assay is best, the present most widely used method for disinfection of bactericidal effect.The method and apparatus of generally taking is to obtain higher temperature by the hermetic container high-pressure saturated water vapor that is produced of heating, usually its internal pressure is more than the pressure of 1.05kg/cm2, temperature reaches more than 120 ℃, but because the very high pressure vessel that belongs to of its internal pressure, therefore general family uses and has certain potential safety hazard, and has the shortcoming of complicated operation.
Summary of the invention:
The objective of the invention is to overcome the deficiencies in the prior art part, a kind of method and device that produces the superheated steam sterilizing under the atmospheric pressure state is provided.
For achieving the above object, method provided by the invention is: it may further comprise the steps:
A, elder generation form superheated steam (about 300 ℃) with common steam (about 100 ℃) through post bake;
B, in time with the overheat steam jetting that forms in the hermetic container that tableware to be sterilized is housed to table-ware disinfection to be sterilized;
C, the steam that temperature in the container is reduced are taken away, and mix with common steam and to be heated to be superheated steam once more and to circulate repeatedly, till with tableware thorough disinfection to be sterilized.
For achieving the above object, device provided by the invention is: it includes a cabinet that holds tableware to be sterilized, on the sidewall of cabinet or rear wall, be provided with superheated steam circulation generation system, this superheated steam circulation generation system includes steam generator, superheater, air extractor and air channel, this steam generator is connected with superheater by passage, superheater offers to the jet puff prot of cabinet inner chamber, superheater also is communicated with the air channel for vapor recycle, the other end in this air channel is connected with the air extractor that extracts Low Temperature Steam, and the air extractor place is provided with blower fan.
Described superheater is made up of housing and heater element.
Described heater element surface pressing has the metal fin that increases heating area.
Described metal fin is parallel shape or helical form.
After the present invention adopts technique scheme, steam generator common steam (about 100 ℃) is carried out post bake through superheater and is formed superheated steam (about 300 ℃), enter kill bacteria on the tableware that the kitchen cabinet internal spray puts in kitchen cabinet inside then, the steam that interior cavity temperature reduces is taken in circulating fan action simultaneously away, and mixes with the common steam that steam generator produces once more that heating enters the kitchen cabinet inner chamber through superheater, form lasting superheated steam and constantly be injected on the tableware.Because cavity temperature is more than 125 ℃ in the kitchen cabinet, and the persistent period can reach more than 25 minutes, can kill escherichia coli, harmful pathogenic bacteria such as staphylococcus aureus.
Description of drawings:
Accompanying drawing 1 is operation principle sketch map of the present invention;
Accompanying drawing 2 is the structural representation of sterilization and disinfection device of the present invention.
The specific embodiment:
The present invention is described further below in conjunction with a preferred embodiment and accompanying drawing thereof,
See shown in the accompanying drawing 1 that method of the present invention is with usual way aqueous water to be become common steam (about 100 ℃) earlier, common steam forms superheated steam (about 300 ℃) through post bake; Then in time with the overheat steam jetting that forms in the hermetic container that fills tableware to be sterilized to table-ware disinfection to be sterilized; In time the steam that temperature in the container is reduced is taken away, and mixes with common steam and to be heated to be superheated steam once more and to circulate repeatedly, till with tableware thorough disinfection to be sterilized.
See shown in the accompanying drawing 2, the device preferred embodiment that utilizes the superheated steam sterilizing of the present invention includes a cabinet that holds tableware to be sterilized, in the interlayer of the sidewall of cabinet, be provided with superheated steam circulation generation system, this superheated steam circulation generation system includes the steam generator 1 that produces common steam (about 100 ℃), this steam generator 1 is connected with superheater 2 by passage, can produce the superheated steam of (about 300 ℃) by this superheater 2, also have simultaneously the effect of mixed vapour concurrently, superheater 2 offers to the jet puff prot 2a of cabinet inner chamber 3, superheater 2 also is communicated with the air channel 4 for vapor recycle, the other end in this air channel 4 is connected with the air extractor 5 that extracts Low Temperature Steam, air extractor 5 places are provided with blower fan, during work, blower fan can be extracted into the steam that temperature reduces in the superheater 2 by air extractor 5, and it is heated once more to recycle in superheater 2.
For having the heat-generating pipe 2c (heater element) of helical form stainless steel metal fin 2d, pressing forms in the superheater 2 of this preferred embodiment, heat-generating pipe 2c is fixed in the closed stainless steel metal shell 2b, because it has very high heat conduction efficiency, common steam (about 100 ℃) can be heated to more than 300 ℃ in the short time rapidly.
The embodiment of the above is preferred embodiment of the present invention only, is not to limit practical range of the present invention with this, so the equivalence that all shapes according to the present invention, structure and principle are done changes, all should be covered by in protection scope of the present invention.
