Microwave dryer is a new type of heating. No fuel, no boiler, no pollution, no energy consumption, no heat conduction, uniform heating, simultaneous heating inside and outside the material, and fast drying speed. For chemical products with water content below 35%, the drying speed can be shortened hundreds of times. .

When microwave heating, the microwave energy directly acts on the medium molecules to convert into heat energy. Since the microwave has the penetrating property to simultaneously heat the inside and outside of the medium, no heat conduction is required, so the heating speed is very fast, and at the same time, regardless of any shape of the object, the medium inside and outside of the object is simultaneously heated. The temperature difference between the inside and the outside of the material is small, the heating is uniform, and the condition of external coke in the conventional heating does not occur, so that the drying quality is greatly improved.

First, the process:

Material to be dried→Special lower hopper→Conveyor belt→Microwave suppressor→Microwave heating drying oven→Dehumidification system→Temperature control system→Microwave suppressor→Finishing hopper

Second, the microwave dryer process notes:

1. The nickel hydroxide to be dried is a little sticky, and the hand will stick together. In order to ensure the uniformity of the blanking, it is necessary to design and manufacture a special lower hopper.

2. During the drying process, the water content of nickel hydroxide is gradually reduced and powdered. The amount of wetted air should be designed to be adjustable and adjusted to the appropriate amount of moisture to prevent the nickel hydroxide from being discharged by the wind.

3. When the nickel hydroxide is dried to the later stage, the water content is reduced to less than 1%. At this time, the microwave power should not be too large to prevent the rebound and the magnetron.

Third, has the following advantages:

1. High thermal efficiency. Since the heat directly comes from the inside of the dry material, the loss of heat in the surrounding medium is extremely small, and the microwave heating chamber itself does not absorb heat and does not absorb microwaves, and all of the radiation acts on the material, and the heat efficiency is high.

2. The microwave can instantaneously penetrate the heated substance, and only needs to be heated for several seconds to several minutes without preheating. Stop heating is also instantaneous, no residual heat.

3. The microwave power is adjustable, and the user can adjust different microwave power according to the requirements of the materials when using.

4. Since all parts of the object to be heated are simultaneously heated, the whole object can be uniformly heated inside and outside, and the temperature difference between the surface of the object and the inside is not generated as in general conduction heating.

5, easy to control, easy to operate and flexible. Automatic control of heating time and drying temperature.

6, microwave energy directly acts on the material, energy loss is small.

7. The equipment is all made of industrial grade stainless steel.

8. The production intensity is small and the land occupation is small.

9, labor-saving, provincial processes, especially easy to connect with the front and rear process into automatic lines, reducing the number of handling.

10. Environmental protection, no sewage, sewage, and slag discharge. The use environment is clean, hygienic and noise free.

11, can easily use the amount of power to adjust the heating state, easy to operate!

Fourth, the scope of application:

Microwave dryer can also be used for drying other chemical powder materials, such as: battery material, silicon oxide, zirconia, calcium carbonate, activated calcium carbonate, nano-scale ultra-fine calcium carbonate, magnesium carbonate, aluminum hydroxide, stand De powder, microspheres, catalyst, magnesium hydroxide, copper sulfate, nickel sulfate, iron oxide red, lithium hydroxide, zirconium hydroxide, etc. are dried.
