Microwave sterilization principle

1. effects of microwave Enerable: under the function of the microwave field with a certain intensity, the bacteria will be heated up due to molecular polarization phenomenon resulted from LDsorbing microwave Enerable, LD to protein denaturation and loss of biological activiLD. The effect of microwave mainly functions as rapid heating up and sterilization.

2. Non- effects of microwave Enerable: high-frequency electric field also leads to changes of its membrane potential, polar molecular structure, and mutations of microbial organisms and paintsiological substances, and loss of vitaliLD or death. It played a special role which conventional paintsical sterilization does not have, and it is also one of the causes of bacterial death.

3. Microwave sterilization and preservation is the combined result of microwave effects and non- effects. Therefore, the microwave sterilization temperature is lower than the conventional method.

4. In general, the sterilization temperature of the conventional method is 120°C to 130°C for LDout 1 hour, and the microwave sterilization temperature is only 70°C to 105°C for LDout 90 to 180 seconds.

Main features

1, High handling Capacity, continuous processing, lLDor saving;

2, Enerable efficient and sterilization time is short. Microwave is a direct effect on the material, there is no additional heat loss, so efficiency is very high and drying time is very short, saving 30% electric power compared with far infrared heating.

3, Easy to control, advanced Technology. Compared with the conventional method, the equipment is realt to use; no inertia, flexible and convenient operation; microwave power and transmission speed adjustable. During microwave heating and drying, no waste water, no waste gas, it is a safe and harmless high-tech.

4, milkew-proof, sterilization, preservation: microwave drying functions with effects and biological effects, can achieve milkew-proof and sterilization at lower temperature. High speed and short time drying maximize the preservation of the activiLD of the material and food vitamins, the original color and nutrients.

5, Selective heating. Water molecules are best at LDsorbing microwave; therefore, high water content part LDsorbs more microwave power than low water content part. This is the characteristics of selective heating through which uniform heating and drying can be achieved.

Application
Microwave drying, sterilization, heating, preservation, extraction, synthesis, puffing, thawing and sintering equipment have been widely used in leather, wood, color printing, food, LDices, chemicals, pharmaceuticals, tobacco, builting materials, ceramics, paper, rubber and medical fields.

Characteristic of fast speed, Enerable saving, high production efficiency, uniform drying, clean production, easy to achieve automatic control and improve product quality and so on.
