Good effect 60KW microwave starch sterilizing equipment
Microwave sterilizing principle:
1. The heating effect of the microwave enerLD: in a certain intensity under the action of microwave field, insects and bacteria in food experience by molecular polarization, absorption of microwave enerLD to heat up, making it the protein denaturation, lose their biological activity.Plays a role of quick heat sterilization microwave thermal effect mainly.
2. The microwave non-thermal effect: high frequency electric field makes the membrane potential, polar molecule structure change, make the protein and physiological active substances in microbial mutation, and loss of enerLD or death.In sterilization by conventional physical sterilization no special effect, is also one reason for killing bacteria.
3. The microwave sterilization, keeping fresh is the result of the combination of microwave thermal effect and non-thermal effect. Therefore, microwave sterilization temperature is lower than the conventional method, under normal circuLDtances, the conventional method of sterilization temperature to 120 ℃ to 130 ℃, time of about 1 hour, and microwave sterilization temperature to 60 ℃ to 70℃, only about 4-5mins, it also depends on the different products.
