microwave dryer/microwave sterilizing canned food drying machine

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.

1,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.

2,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.

3, Detailed introduction

1. High enerLD conversion efficiency, fast heating, low enerLD loss

2. Advanced craft, easy to control, fast heating, wonderful roasting effect

3. Microwave roasting simultaneously, along with bactericidal effect

4. Low-temperature roasting, less nutrition loss, roasting without oil, better for health.

4, Mainly application

Microwave industrial tunnel baking&puffing&roasting equipment are widely used in the peanut, sesame seeds, wheat, melon seeds, sunflower seeds, peanuts, corn, soybeans, walnuts, almonds, chestnuts, pistachios, cashews, filbert and dried fruit etc; and for leisure food, pachyrhizus chips, potato chips, dried shrimps, fish maw and so on.

Compared with the traditional production methods, microwave baked foods are crispy and delicious, products particle puffed full, natural color, beautiful appearance, and has insecticidal sterilization effect.

5,Microwave roasting features:

1. EnerLD conversion efficiency high, fast heating.

Microwave oven itself, but microwave enerLD fever, make the material through materials within polarity produced molecular friction between internal heat. Make the liquid inside processed materials instantaneous warming vaporization, boosting inflation; And depend on gas expansion force make component of macromolecule substance, and become a structural degeneration areolar tissue structure characteristics, finalize the design of microporous shape more than substance.

2. when microwave baking ,sterilization effect at the same time.

Microwave sterilization is in the microwave heating and the dual role of non-thermal effect under the temperature sterilization, compared with conventional in lower temperature and very short time get satisfactory antiseptic effect. General sterilizing temperature around in 80 °C, the processing time in 3 ~ 5 minutes, and to the maximum maintain its nutrients.

3.The operation is convenient.

Microwave power and conveyor belt speed can adjust arbitrary

, both thermal inertia, but do not exist, simple, easy to open namely stop control. Improve the production environment. Microwave equipment nirvikalpa radiation, no dust, no noise, no pollution, easy to realize the food hygiene inspection standard.

4. Puffed effect roast is obvious.

Microwave fast heating effect, make the material internal water molecules, achieve rapid vaporization ,reach to the puffed and roast purpose.

5. Low temperature sterilization, nutrition loss less.

Microwave sterilization is in the microwave heating and the dual role of non-thermal effect under the temperature sterilization, compared with conventional in lower temperature and very short time get satisfactory antiseptic effect. General sterilizing temperature around in 80 °C, the processing time in 3 ~ 5 minutes, and to the maximum maintain its nutrients. The reserves of vitamin C conventional heat treatment fruits and vegetables is 46% ~ 50%, microwave, can reach 60 ~ 90; Keep to vitamin A conventional heat treatment is 58 percent, and microwave treatment is to 84%, and would not affect the original flavor, is the fruit and vegetable food processing, obtain the good means green food.
