Microwave drying machine for polymer materials, microwave drying machine for chemical raw materials

Microwave drying machine for polymer materials, microwave drying machine for chemical raw materialsApplied to fast drying of products in different industries such as food, medicinal herbs, wood, chemical products, building materials, cardboard, ceramics, etc. Compared with traditional drying equipment, microwave drying equipment is characterized by fast drying speed, high efficiency, environmental protection and energy saving, and is a new type of equipment that responds to low-carbon economy.

Microwave drying machine for polymer materials, microwave drying machine for chemical raw materialsWorking principle: By using the penetrating heating of microwaves to increase the temperature of materials, the moisture in the materials is vaporized and evaporated. The evaporated water vapor is discharged by the dehumidification system to achieve the purpose of drying the materials.

Characteristics of microwave drying:

Linearity: Similar to visible light, it propagates in a straight line.

Reflectivity: When encountering a conductor such as a metal object, it reflects light waves like a mirror, and the metal does not absorb microwaves.

Absorption: It is easily absorbed by polar molecules (such as water) and converted into thermal energy.

Penetration: Microwaves are not absorbed by non-polar molecules (insulators such as ceramics, polypropylene, etc.), do not generate heat, but can penetrate these objects.

Alternative names and application equipment for microwave drying equipment: tunnel type microwave dryer, microwave drying oven, microwave food drying equipment, microwave agricultural and sideline product drying equipment, large microwave drying oven, etc.

The main application objects of microwave chemical drying equipment include: glass fiber, chemical raw materials, starch cobalt oxalate, cellulose (such as cellulose, carboxymethyl cellulose, etc.), nickel hydroxide, lithium cobalt oxide, graphite, carbon brush, silicon carbide, calcium chloride dihydrate, activated carbon, zirconium oxychloride, zirconium oxide, zirconium hydroxide, zirconium carbonate, zirconium sulfate, ammonium zirconium carbonate, zirconium silicate, potassium zirconium carbonate, oil-based ink drying agent, water-based ink cross-linking anti water agent, expandable ceramic zirconia, nano iron oxide, etc ........

There are many types of powder raw material drying equipment and microwave chemical raw material drying equipment. Chemical raw material drying (drying) equipment is used for rapid drying and dehydration of powdery, granular, paste like materials, such as cobalt oxalate, nickel hydroxide, dry dew pure, ammonium paratungstate, lithium cobalt oxide, nano material silicon dioxide, etc. The moisture content reaches 0.5% after drying from 40%, and the drying time only takes 5-6 minutes.

In addition to powdered, granular, and block materials, if there are other chemical materials that need to be dried, whether high-temperature drying or low-temperature drying is required, they can be customized according to requirements.

Chemical raw material dryers are customized according to different material characteristics, drying requirements, and drying output. Due to the wide variety and scope of chemical products, as well as the distinct differences in material characteristics, it is difficult to systematically classify drying equipment. So for now, we will classify the dried materials based on their appearance and shape. It is divided into powder drying equipment for small particles, granular product drying equipment, block product drying equipment, and emulsion product drying equipment. It can dry chemical products with a moisture content between 3-50%, and the drying speed is dozens of times faster than traditional drying speed, making it a good helper for chemical product production enterprises!

The chemical raw material drying equipment adopts microwave technology, with PLC control design for automatic temperature control, automatic detection of material shortage and shutdown. The inner and outer shells are made of all stainless steel and can be produced 24 hours a day. The application of variable frequency switch power supply technology effectively reduces processing costs and equipment operation loads.

The mixed powder material drying equipment is suitable for drying powder materials with a moisture content of about 5-30% and strong absorption ability, such as graphite powder and silicon carbide drying.

Products that are naturally loose can be dried using a regular feeding hopper, while products with high moisture content and viscosity require vibrating or stirring feeding hoppers.

Drying process flow: feeding hopper storage - natural feeding or mixing feeding - entering the drying tunnel - drying treatment (adjustable, controllable) - discharging cooling - product storage

Advantages of Microwave Drying for Chemical Materials:

1. Uniform heating: Due to the microwave acting on water molecules, the parts with higher water content absorb more microwave power than the parts with lower water content. This is the characteristic of selective heating, which can achieve uniform heating and uniform drying.

2. High energy-saving efficiency: Microwave directly acts on materials, so there is no additional heat loss. The air inside the furnace and the corresponding containers do not heat up, so the thermal efficiency is extremely high and the production environment is significantly improved. Compared with far-infrared heating, it can save 30% of electricity.

3. Time saving, labor-saving, and short time: Due to the fact that microwave heating does not require thermal conduction, microwaves penetrate objects from different directions and enter the interior of the object, allowing the material to dry uniformly from inside out in a very short time, effectively shortening the drying time.

4. Easy to control: Compared with conventional methods, the PLC control panel is easy to operate, with adjustable microwave power and transmission speed.

5. Drying speed: 3-8 minutes.
