The purpose of this utility model provides a kind of low temperature rise microwave sterilizating decontaminating apparatus that can effectively kill the inner antibacterial of article under the article temperature raises small situation.
The solution that realizes this utility model purpose is: the low temperature rise microwave sterilizating decontaminating apparatus that is provided comprises a microwave source and microwave sterilization case.Wherein microwave source is the microwave source of intermittent radiation microwave, and its microwave radiation frequency f is 640MHz～2160MHz; The microwave sterilization case is surrounded by copper coin or aluminium sheet; Also be provided with the residual amount of energy absorber at microwave sterilization case end; To the distance of the residual amount of energy absorber length as disinfect box, then the width L of disinfect box is 109.5-292.3mm, and the width L of microwave radiation frequency f and aforesaid disinfect box should meet relational expression f＞1.51 * 10 with microwave entrance
10/ L, L unit is cm in the formula.
The applicant thinks: will make when the bacterial body of hyperfrequency electromagnetic field effect in colonizing in article that conductive materials and electrolyte produce conductive electric current and the current of polarization identical with adding electromagnetic field frequency in its body.If these electric currents are during considerably beyond the bioelectric current of bacterial body, bioelectric current will " be swallowed up ", and life process will stop.But bacterial body has certain adaptive capacity to environment, so can only kill the parts of fine thalline behind microwave of emission, also has the bacterial body of considerable part to be in temporarily " dormancy " state.The intermittent transmission microwave is adopted in evidence, acts on the bacterial body, then can break " dormancy " of bacterial body, and it is killed.
Microwave frequency and its penetration capacity to article have direct relation.Though the microwave of lower frequency has stronger penetration capacity, its act on conductive electric current that antibacterial produces also a little less than, can not reach the purpose of kill bacteria; And its energy attenuation when article of the microwave action of upper frequency is bigger, can not effectively kill the antibacterial that colonizes in article inside.The applicant is through evidence: when microwave frequency is in the 640-2610MHz scope, both can guarantee to kill the antibacterial of article inside, and not waste energy again
In order to guarantee that microwave energy accumulates in the disinfect box, and uniform distribution, disinfect box adopts the good conductor material of copper or aluminum and so on, and its size should meet aforesaid requirement.The effect of residual amount of energy absorber is to be converted into heat energy dissipation after the microwave energy of remnants is absorbed to fall, and prevents that microwave reflection from returning microwave source and causing the lost of life or the damage of microwave source.
This utility model is owing to having adopted the principle of intermittent radiation microwave energy to come the kill bacteria live body, so energy consumption is low, sterilization time short.Generally speaking in 5 minutes, output energy be not more than 30 joules can be with the inside killing bacteria of article such as bundled bank note, books, wherein the coccus killing rate can reach 100%, the bacterial spore killing rate can reach 99.2%.The temperature rise of article was very little when another advantage of the present utility model was sterilization.Therefore, not only can sterilize, and can provide an effective way for some at high temperature perishable article sterilizations as cosmetics and so on for dry goods.
