Conveyor belt microwave drying and sterilizing machine
for tea
Application
Microwave drying equipment are mainly used for drying all kinds of teas,herbs, acanthopanax, tobacco, mint leaves, leaves, medicinal herb, calendula, cornflower, raspberry, blaeberry, oregano leaves, liquorice tables, olive leaves, stevia leaves, flowers, green leaves, such as wild chrysanthemum flower,broadleaf holly leaf, olive leaf, lotus leaf, honeysuckle , green tea,black tea,puer tea, flower tea.
The principle of microwave drying
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 enerLD can be converted to heat enerLD in medium to rise the temperature of materials.accomplishing heating ,puffing and a series of physical and chemical processes ,and so ,microwave heating is achieved.
The principle of microwave sterilizing
Microwave sterilizing is the result of combined action of the thermal effect of electromagnetic 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 ion 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.
