Because rubber compound is bad heat conduction material, it is easy to dry natural rubber compound by using hot air medium burning diesel oil to dry natural rubber compound, which can easily cause the surface layer of rubber to dry first, bond and melt with each other, and the central part of rubber particle appears “white core”, that is, the phenomenon of not parch, which leads to the instability of rubber quality.

Microwave Rubber Drying Technology

Microwave drying has the advantages of fast drying rate, high production efficiency, uniform drying and low energy consumption. It is widely used in grain, chemical, pharmaceutical and other industries. The results show that good results have been obtained in the study of the structure and properties of natural rubber and its composites combined with the morphology or ultrastructure of the materials.

The advantages of microwave rubber drying process used in Leader Microwave Equipment Company equipment:

1. Compared with the traditional hot air drying, the microwave drying time is significantly shortened (from3-4 hours to 15-25 minutes), the production efficiency is high, and a lot of energy needed for long time heating is saved. Microwave rubber drying technology has important application value in the field of natural rubber drying.
2. Microwave rubber drying method is used to clean production, and it is uniformly dried, which reduces the adhesive, the clamping and hot viscous phenomenon, and improves the consistency of the product. Microwave-dried sheet rubber has better effect than granular adhesive, which fills the gap between domestic and abroad.
3.  In the existing rubber processing plant, microwave rubber drying method is used to dry natural rubber. In addition to the drying process, the original process and equipment can be used in other processes, which reduces the granulation equipment, saves the investment of the factory, and reduces the discoloration of the film mold. Microwave rubber drying technology is easy to popularize and use.
4. The natural rubber which is dried by the rubber microwave drying technology reach the technical requirements of GB/ T8081.
5. Before and after drying of microwave rubber drying process, the surface structure of rubber remained basically unchanged, and the physical and mechanical properties were basically the same as those of hot air drying, but the aging properties of rubber were better than those of natural rubber dried by hot air.

There are many unfavorable factors and problems in the traditional hot air drying of natural rubber:

1.The drying time is long and the heat utilization rate is low.

2.It has a certain influence on the quality of natural rubber. The principle of drying natural rubber in hot air medium is that the drying temperature is transmitted from the surface of the material to the inner layer, the moisture of the wet rubber material diffuses from the inner layer to the surface layer, and the direction of heat conduction is opposite to the direction of water diffusion. But rubber material is bad heat conduction material, heat conduction is slow, cause rubber compound surface layer to dry first, crust, bond with each other and melt with each other, block rubber material capillary, cause rubber compound inner layer moisture to diffuse to surface layer, easy to appear drying incomplete namely “entrapment” or sticky phenomenon.

3.And has the advantages of serious environmental pollution and high production cost.

The application prospect of microwave drying technology:

Microwave rubber drying technology is different from the traditional drying method, and its heat conduction direction is the same as that of moisture diffusion. Compared with the traditional drying method, microwave rubber drying process has many advantages, such as high drying rate, energy saving, high production efficiency, uniform drying, cleaner production, easy to realize automatic control and improve product quality, so it has been paid more and more attention in various fields of drying.

Natural rubber industry is a strategic industry related to national security and national defense development in China. At present, the output of natural rubber in China is about 50-600000 tons. The main products are standard adhesive, tobacco film, white crepe and so on. Microwave rubber drying technology has a broad prospect.

In addition, with the progress of industrialization in China, energy saving and consumption reduction have become an important part of scientific research in China. Therefore, the application of microwave rubber drying technology in various drying fields will be carried out more widely and deeply.

High degree of automatic production line, reduce labor costs, reduce human operation errors, improve production efficiency.

Drying principle of marble microwave drying equipment:

When the dielectric is placed in the alternating electromagnetic field, the molecule with asymmetric charge is excited by the alternating electromagnetic field and rotates. Due to the irregular thermal motion of the original molecule in the material and the interaction between the adjacent molecules, the rotation of the molecule is interfered and limited, resulting in a “friction effect”. As a result, part of the energy is transformed into the thermal motion function of the molecule, that is, it is expressed in the form of heat, so that the material is heated. That is, electric field energy is converted into potential energy, and later it is converted into thermal energy, so as to achieve drying purpose. Using this principle, the microwave brown pillow type drying machine can produce high-quality brown pillow.

China is rich in natural marble and quartz mineral resources. At present, the market demand for natural marble, artificial marble and artificial quartz is also increasing. It is urgent to make rational use of rich resources to meet the huge demand. Marble microwave drying equipment is a new choice for stone processing industry because of its safety and efficiency, health and environmental protection, low cost and high yield.

Microwave drying equipment

Difference between microwave drying equipment of tremella and traditional drying method：

The traditional drying method is to take the normal pressure wet air as the drying medium and use steam and hot water as the heat medium to indirectly heat the air. The air heats tremella in the form of convection to achieve the drying method. But the traditional drying method has many disadvantages.

1.Large temperature difference

In the process of traditional drying method, heating from outside to inside makes a big difference in temperature. In this way, drying degree and final fineness of dried tremella are different, but microwave drying equipment of tremella can be uniformly heated.

2.Poor energy saving effect

Traditional drying methods involve the use of all kinds of energy, which not only leads to the waste of energy, but also to the increase of cost. Manufacturers who use natural drying will greatly reduce their production efficiency once it is cloudy and rainy. In the drying process, the microwave drying equipment of tremella only uses a small amount of electric energy, which saves a lot of resources.

3.Severe pollution

No matter using coal drying or gas heating drying, it will produce certain waste gas and waste water and other products that pollute the environment. The tremella microwave drying equipment uses microwave drying to completely eliminate these problems.

4.Many safety risks

The traditional drying method uses the heating method for drying, which has many safety risks, such as fire, gas explosion and so on, but the tremella microwave drying equipment will not have these problems.

Characteristics of Microwave Drying Equipment for Tremella

At present, the drying treatment method of the extrusion and granulation of engineering plastic raw materials generally adopts a hot air drying hopper. The electric heating wire is blown by a hair dryer to spread the heat. Not only is it energy intensive, but it is also less efficient. Another drying method uses the honeycomb spinning molecular sieve drying principle. The main disadvantage is that the molecular sieve regeneration process consumes a lot of energy. At the same time, the drying process will also cause oxidation of the raw materials, which consumes energy and does not protect environment.

The principle of vacuum drying:

In the vacuum environment, the boiling point of water in the plastic raw material decreases with the increase of the vacuum degree, the water molecules are converted into water vapor from the liquid boiling to actively overflow from the plastic raw material, the vacuum pump is taken out to the outside to achieve the drying purpose. The gas pressure is lowered and the boiling point of the water is also lowered (for example, at an atmospheric pressure of 101.3 kPa, the boiling point of water is 100 ° C, and at 7.37 kPa, the boiling point of water is 40 ° C). In vacuum conditions, heating the object allows the internal moisture of the object to evaporate without temperature rise.

The principle of microwave drying:

Microwaves have electromagnetic field energy. Microwave heating is an extremely high-frequency electromagnetic oscillation that acts on the material molecules with electrodes，causing the molecular arrangement to change dramatically, resulting in a fierce “friction”-like effect. Make the object hot. This process converts the electromagnetic field energy of the microwave into thermal energy. Water molecules are polar molecules that strongly absorb microwaves. When the moisture-containing material is subjected to microwave radiation of sufficient field strength, the water molecules absorb the microwaves and quickly evaporate, and the materials are quickly dried.

The theoretical basis of the dual temperature measurement microwave vacuum test furnace:

Microwaves provide the fastest way to transfer energy into a biosolid. In microwave drying, the water inside the material evaporates into water vapor in situ. The water vapor pressure is greater than the pressure of the external environment to create a positive pressure differential that drives the water vapor to move toward the surface of the material. The energy of the microwave and the dielectric constant of the material determine the efficiency of microwave conversion to heat, which fundamentally determines the drying rate of microwave drying.However, in normal pressure, the microwave rapidly raises the temperature of the material to the boiling point of the water, resulting in too high a temperature of the material and a deterioration in the quality of the dried product.
