cocoon microwave drying machinery

Main features:

Microwave drying is a kind of advanced heating dry technology, with high thermal efficiency, the processing time is short, the dry uniform, to the heating material characteristics, such as small destructive, already in food, medicine, feed processing of widely used. For cocoon , the purpose is dry in the cocoon silkworm, protection of the external cocoon layer. By microwave drying is undoubtedly an ideal method, which is both at home and abroad to carry out some useful exploration. But, by microwave drying internal heat, from material reached too fast, vulnerable to pupa "explosion in formation, spray print the cocoon, influence cocoon quality This equipment and microwave baking process to solve the silkworm cocoon "critical" problem, spray equipment successful export Turkey.

The principle of microwave sterilizing

Mircowave sterilizing is the result of combined action of the thermal effect of eletromgnetic fields and the biological effect.Thermal effect of microwave on the bacteria denatures the protein of bacteria ,and make the bacteria lost the condition of nutrition,reproduction and survival so as to die .The biological effects of microwave on the bacteria is that the microwave electric field changes the potential distribution of cross-section of the bacterial cell membrane and impacts the concentration of electron and lon around the membrane ,and changes the permeability of cell membranes ,therefore the bacterium become innutrient and lost normal metabolism.The structure and function of bacterium fall into disorder ,and theirs growth are inhibited ,as a result they are dead.Moreover ,nucleic acid genetic(RNA) and deoxyribose acid (DNA),which decide the normal growth and stability of bacterial,are curly-shaped macromolecule made of a number of linked compactly hydrongen bond .The microwave can be strong enough to make hydrogen bond stack ,rupture and recombine ,and induce intragenic mutation or chromosome aberration and even rupure

The principle of microwave heating:

Microwave is a sort of electromagnetic wave which frequency is 300MHz to 300GHz .The water molecule in medium materials is polar molecule,under the effect of the rapid change of electromagnetic field,its polarity orientation will alter with the changes of the external electric field with the high-speed,causing the movement and friction of molecule.so that the microwave field energy can be converted to heat energy in mudium to rise the temperature of materials.accomplishing heating ,puffing and a series of physical and chemical processes ,and so ,mircrowave heating is achieved.
