Using samsung magnetron water-cooling oriental persimmon microwave drying and sterilization machine dryer dehydrator with CE

Microwave sterilization principle

1. Thermal effects of microwave energy: under the function of the microwave field with a certain intensity, the bacteria will be heated up due to molecular polarization phenomenon resulted from absorbing microwave energy, Using samsung magnetron water-cooling oriental persimmon microwave drying and sterilization machine dryer dehydrator with CE to protein denaturation and loss of biological activity. The thermal effect of microwave mainly functions as rapid heating up and sterilization.

2. Non-thermal effects of microwave energy: high-frequency electric field also leads to changes of its membrane potential, polar molecular structure, and mutations of microbial organisms and physiological substances, and loss of vitality or death. It played a special role which conventional physical 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 thermal effects and non-thermal 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 about 1 hour, and the microwave sterilization temperature is only 70°C to 105°C for about 90 to 180 seconds.

Main features

1, High handling capacity, continuous processing, labor saving;

2, Energy efficient and sterilization time is short. Microwave is a direct effect on the material, there is no additional heat loss, so thermal 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 ready to use; no thermal 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, Mildew-proof, sterilization, preservation: microwave drying functions with thermal effects and biological effects, can achieve mildew-proof and sterilization at lower temperature. High speed and short time drying maximize the preservation of the activity of the material and food vitamins, the original color and nutrients.

5, Selective heating. Water molecules are best at absorbing microwave; therefore, high water content part absorbs 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, spices, chemicals, pharmaceuticals, tobacco, building materials, ceramics, paper, rubber and medical fields.

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