tunnel type continue produce microwave dryer for food process
Main application
This machine fits for drying and sterilizing powders, granular, sheet-like or gel-like food, and additive, spices, flavoring, medicine, raw material of herbal medicine, nutritional health products, agricultural & sideline products, non-fired(or oil saving)instant noodles, noodles, rice powder needles, soy products, beef jerky, preserved meat, dried fish, tea, tobacco and so on; and for drying, peeling and baking almond, peach kernel, groundnut kernels, chestnut and so on; and for puffing of leisure food, pachyrhizus chips, potato chips, dried shrimps, fish maw and so on; and for sterilizing and oral liquor, pickles, a variety of small packaging food; and for thawing the frozen fish, poultry; and for drying beans; and for drying and desulfurating and deoxidizing the metallurgical chemical products; such as oxalate cobalt, sulfur powder, mid-ammonium tungstate, nickel hydroxide, bluestone, iron core, magnetic core and magnetic resonance organ, magnetic boards, disk, alveolate ceramic, plaster products; and for drying printing and dyeing products, ceramics, glass, chemical fiber, cotton yarn, wood, leather, bamboo products, insulation materials, building materials, wood , cork, alveolate, cardboard,corrugated cardboard, and so on.
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 energy can be converted to heat energy 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.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 hydrogen bond .The microwave can be strong enough to make hydrogen bond stack ,rupture and recombine ,and induce intragenic mutation or chromosome aberration and even rupture.
The main heating feature:
1, Fast heating. Microwave heating is completely different with traditional heating mode. It makes heating medium become heater, do not need heat transfer process. Although thermal conductivity is poor materials, also can achieve heating temperature in a very short time.
2,Save energy and efficiency. Because materials contain water absorb microwave easily and fever, so in additionto a small amount of transmission loss outside, almost no other loss, so high thermal efficiency, save energy. 3, Heating even. No matter how shape of each part of the body, microwave heating all can make the object and evenly infiltration and electromagnetic wave list to produce the heat. So heating good uniformity, won't appear the endogenous phenomenon focal. 4, Mouldproof, sterilization, fresh. Microwave heating has thermal and biological effect, can sterilize and mould proof in low temperature. Due to heating rapidly, the time is short, can maximum limit save material activity and thevitamin original colour and lustre and nutrition of food. 5, Craft is advanced, control easily. Microwave heating just have the basic conditions of water, electricity, as long as control power, can realize microwave heating or terminate immediately, use microwave equipment can process automation control of heating process and heating process specification.
