Drying principles of microwave resin drying equipment:

The microwave drying technology of microwave resin powder drying equipment has a unique heating mechanism which is different from conventional drying.It is mainly manifested in the difference of migration potential and its gradient direction.

In traditional heat drying,a heat source transfers heat from the outside to the inside of the resin,evaporating the water.The initial impetus for energy transfer is the temperature gradient. Water is transferred from the inner layer of the resin to the surface layer to the hot wind in the form of steam,which needs to overcome the resistance of the air film.In the conventional drying process, the diffusion direction of steam is opposite to the temperature gradient, which  blocked diffusion and reduced heat transfer efficiency.

In the heating process of the Microwave resin drying machine produced by  Leader Microwave Equipment Company,the absorption of heat energy and dehydration process of dried resin powder are not completely determined by the thermal conductivity properties of the drying medium and itself.So the thermal resistance is negligible.

The dielectric loss factor of a substance is proportional to its absorbing property, that is to say, a substance with a large loss factor can better absorb microwave energy in the microwave field.From the macro point of view, microwave is preferred to heat the material with large dielectric loss factor, while the material with small dielectric loss factor is slow to be heated, that is to say, microwave has the characteristic of selective heating.

Since the dielectric loss factor of water is much higher than that of common minerals or materials, microwave can selectively heat water, rather than the whole resin powder, so the microwave radiation has unique advantages in water removal during the drying process.

As a new drying method, microwave heating has the characteristics of selective dielectric heating, high dehydration efficiency and energy saving:

1.Compared with conventional drying method, microwave drying equipment can dry resin powder quickly and efficiently.

In the drying process of resin powder microwave drying equipment,all the water in the powder, namely the inner layer and the surface layer, is selectively heated by microwave at the same time. When the water is heated, it will instantly vaporize, while the inner layer and the surface layer of the gas film and air of the powder will produce a huge pressure difference, forming a huge driving force, so that the water will quickly transfer from the powder to the air.

Microwave drying resin powder equipment heating does not need any heat conduction process, directly through the microwave in the resin powder dielectric loss to transfer energy to molecules or atoms, this unique in situ energy transfer mode is different from the traditional heat transfer mode, is conducive to improve the chemical diffusion process and chemical reaction rate.

2.Microwave tunnel type Tenebrio molitor drying and puffing equipment has uniform drying temperature,consistent with the inside and outside.In the drying process of microwave drying equipment, the temperature gradient and heat transfer direction inside the resin powder are the same as that in the water vapor transfer direction, so it is characterized by internal and surface heating, high thermal energy utilization and energy saving.

3.The adhesion, hardness, impact resistance and flexibility of the resin products treated by microwave resin drying equipment have been improved significantly.

4.Microwave resin drying equipment has no pollution in the production process and protects the environment.

Microwave heating and drying process without waste water, waste gas, etc.It is a great improvement to the traditional drying process, further popularization of microwave resin drying equipment, kraft paper bag microwave drying equipment and other microwave equipment can improve environmental damage, which has good social benefits.

Microwave drying technology has unique heating and heat transfer mechanism, and has obvious advantages compared with conventional drying technology: selective heating, high dehydration efficiency, low energy consumption and improving the performance of resin powder.

Microwave drying technology shows many advantages, making it become a highly efficient, energy-saving, economic new technology in the field of drying, which is bound to play an increasingly important role in the material, metallurgy, chemical, food and other industrial production.
