Background technology
Microwave sterilizating is a kind of non-thermal sterilization method that should be comprehensive with heat effect, belongs to low temperature sterilization category, is mainly used in the fields such as biology, medicine, chemical industry, food.Because microwave radiation penetration power is strong, therefore, its application is extremely extensive.In prior art, microwave is as follows to the general form adopting of the sterilizing of material:
One, the sterilizing radiation source of setting is directly to indefinite form stacking material radiation sterilization.Because microwave sterilizating effect is relevant with solid accumulation thickness, so, adopting this class methods sterilizing, sterilizing is inhomogeneous, and sterilization effect is unreliable.Be only suitable in the less demanding solid particle material sterilizing of sterilizing.
Its two, by material subpackage subject to sterilization, material is by microwave irradiation sterilizing.This method has been avoided above indefinite form solid accumulation and the problem such as the sterilizing that causes is inhomogeneous, effect is unreliable.But be difficult to control the sterilizing thickness that material is suitable.
Its three, material subject to sterilization is with the feeding of conveyer belt mode, material is by conveyer belt charging and discharging in a continuous manner in microwave sterilizating chamber, its industrialization operation degree is high, output is large.But, adopting the method, feed cannot be accurate, and sterilizing controllability, repeatability are difficult to reach.Meanwhile, liquid material cannot transmit, and sterilizing element purge is difficult for.Therefore,, for requiring high sterilization process also to need to improve, which is applicable to solid material mostly.
Its four, the radiation irradiation equipment of microwave sterilizating of feeding, blanking, material difficult treatment for to(for) viscous material.
