The best selling production-- green tea &black tea microwave drying &sterilization machine
Microwave is electromagnetic waves which frequency from 300 MHZ to 300000 MHZ. Water molecule of heating medium material is polar molecule, its polarity orientation of the electric field with changes caused by the movement of molecules under high rapid frequency electromagnetic field changes, cause the numerator movement and the friction effect of each othe. Microwave field can field at this time into medium heat, make temperature of material increase, produce and popped a series of materialization process to reach the purpose of microwave heating dry.
Microwave industrial tunnel baking and puffing equipment, roasting equipment, microwave baking equipment,continuous microwave roasting machine,industrial microwave raosting baking machine , drying and sterilization machinery, widely used in the peanuts ,sesame seeds, wheat, melon seeds, peanuts, corn, soybeans, walnuts, almonds, chestnuts, pistachios, cashews and dried fruit etc baking.Compared with the traditional production methods, microwave baking foods are crispy and delicious, puffed full of particles, natural color, beautiful appearance, and has insecticidal sterilization.
Microwave industrial tunnel equipment baking characteristics - high energy conversion efficiency, fast heating.Microwave oven does not heat itself, but the microwave energy penetrate the material, the friction between the polar molecules within the material and produce internal heat.Make the internal liquid of processed material vaporize instantly ,pressurized expansion;and rely on the expansive force of gas,make polymer components structure degenerate,and become a network organization structure characteristics, stereotypes microporous substances.
1 While microwave equipment baking, along with the bactericidal effect. Microwave sterilization reflect in the dual role of thermal effects and non-thermal effects , compared to the conventional temperature sterilization ,can obtain a satisfactory sterilization in lower temperatures and a very short time.The sterilization temperature is around 80°C in general,the processing time is 3~5 minutes,and can maintain its nutrients.
2 Easy to operate. Microwave power and the conveyor speed can be sleepless adjustment, there is no thermal inertia, can open and stop at an time, easy to control,improve the production environment.Microwave equipment, no waste heat radiation, no dust, no noise, no pollution, easy to implement the testing standards of food hygiene.
3 The puffing effect is obvious. The purpose of rapid microwave heating effect, make the material internal water molecules vaporize rapidly,then reach the purpose of puffing.
4 Low-temperature sterilization, less loss of nutrients.Retain vitamin C,conventional heating treatment for fruits and vegetables is 46% ~ 50%, but the microwave can reach 60%~90%.Retain vitamin A,conventional heating treatment is 58%,but the microwave can reach 84%,and does not affect the original flavor, is a good method for deep processing of fruits&vegetables and get green foods.
