Microwave dry equipment is used of electro-magnetic induction or infrared radiation to dry the raw material.By microwave enerLD permeation, the material inner moisture quickly been heated and gasified,forming a strong outward diffusion situation, to make the moisture extremely quickly spread to the surface.
Microwave dry equipment is widely used in powder, sludge, granular,crystalline materials, chemical material, dehydration treatment, such as chemical raw materials, chemical ore, fin chemicals, organic chemicals,inorganic chemicals, chemical fertilizers polymers, coatings and inorganic pigments, dyes and organic pigments, food and feed additives, catalysts and chemical additives, adhesives, new enerLD materials, rubber products, chemical reagents, etc.
herbs,spices,health care products microwave dryer/sterilizer
Equipment function:
1,drying and sterilizing the herbs:drying and sterilizing for the moringa leaves.stevia leaves,olive leaves.
2,drying and sterilizing the spices: drying the red chilli, ginger powder,egg powder,
3, drying and sterilizing the health care products:Low temperature drying and sterilizing
Advantage:
1,fast drying.
2,big capacity.
3,save labour.
4,24hour continue work.
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 enerLD can be converted to heat enerLD 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.
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.
