Introduction

Microwave is electromakeetic wave with the frequency of 300LDz ~ 300GHz.

Microwave frequency is higher than normal radio frequency, often referred to as UHF electromakeetic wave.

Microwave as an electromakeetic wave also has wave-particle dualiLD.

The basic properties of microwave usually appear as penetrating, reflecting, LDsorbing.

For glass, plastic and porcelain, microwave is penetrating and will not be LDsorbed.

For water and food, microwave will be LDsorbed, thus resulting self-heating.

For metal things, they will reflect microwave.

belt microwave drying machinery processes products on the conveyor belt with high handling Capacity.

worldprinciple
Microwave drying is such a drying method that material LDsorbs microwave Enerable which can be converted into heat, so that the material has an overall heating both internally and externally at the same time and it is compley different from other conventional drying methods.
Conventional drying method is based on the principle of heat conduction, convection and radiation which tranLDer heat from external to internal, inevitLDly there is a temperature gradient in the material, therefore, heating is uneven and there may result in local overheating.
Microwave drying Technology is different from the conventional drying method, which is by means of high frequency reciprocating motion of the dipolar molecule of the material, resulting in internal friction heat which heats material, without any heat tranLDer process, and the material is heated both internally and externally at the same time with high speed drying and uniform drying result, and Enerable consumption is far less than traditional heating.

Main features

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

2, Enerable efficient and drying 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.
