Industrial microwave equipment applies the properties of microwaves to industry , making it becomes a streamlined operation serving for industrial production.
Microwave heating has the characteristics of fast heating speed, low heat loss and convenient operation.It cannot only shorten the process time, increase productivity and reduce cost,but also improve product quality.
1.The advantages of Industrial microwave equipment :
Industrial microwave equipment heated evenly and fast
The general heating method is based on heating the surroundings,which can make the surface of an object be heated first through thermal radiation or convection of hot air.Then heat can be transferred through thermal conductor to the interior of the object.It needs long time and low efficiency .
In contrast,the microwave is generated from the inside of the object.The object can be heated evenly because the heat source comes from interior. The phenomenon of “the outside is ripe but the inside is not “ won’t happen. And that, because of heating inside and outside of the object simultaneously,heating time is shortened and heating efficiency is improved,which is good for improving products quality .
2.Industrial microwave equipment with selective heating
There’s a close relationship between wastage of heated object and heat quantity of microwave heating .The dielectric constant of different kinds medium is between 0.0001-0.5 .So there’s a big difference between objects’ microwave absorbing ability . Usually , the bigger the dielectric constant , the easier to heat by microwave . If the dielectric constant is too small , the medium is difficult to heat by microwave .
3.Industrial microwave equipment can be controlled in time and react sensitive
The regular heating method , like steam heating, electric heating, infrared heating, etc , need certain time to arrive at a certain temperature.When it goes wrong or stop ,temperature drops also need long time .Microwave heating can adjust the microwave power to needed value in seconds,and then heat it to the appropriate temperature,making it convenient for automatic and continuous production .
4.Industrial microwave equipment with strong filed of high temperature .
The microwave power absorbed per unit volume in the medium is proportional to the square of the electric field intensity, so that the work piece can be raised to the required processing temperature in a very short time at a very high field strength. Strong field high temperature can also give sterilize effect without the influence of the product quality.
5.Microwave heating with strong penetrating power.
The penetration depth and wavelength of electromagnetic waves are of the same order of magnitude. In addition to larger objects, it is generally possible to heat the exterior and interior together.
The far-infrared heating has a long wavelength, and the penetration ability during heating is poor. Under the far-infrared illumination, only a thin layer of the object generates heat, and the heat is mainly conducted to the inside, so the heating time is long, and the heating result is uneven.
6.Industrial microwave equipment is clean and without pollution
Normally , industry heating equipment has big size and cover large area .The surrounding temperature of it is high ,so the operators had to endure terrible working conditions and great intensity .However ,microwave heating equipment can totally solve that problem with small size and comfortable temperature around , which improve working condition effectively .
Industrial microwave equipment applications:
- Insecticide and mold removal of high moisture viscous materials;
- Insecticide, drying and mildew treatment of foods, medicines and medical supplies;
- Water-removing and improve fragranceoftea, scented tea.
- Drying and sterilization of chemical products such as silicon carbide, single crystal, and thermal insulation board;
- Wood and herbs’ insecticide, mold removal, drying, etc
Industrial microwave equipment is a kind of heating method that completely different from other conventional heating.It relies on objects to absorb microwave energy, which is then converted into heat, heating the whole thing at the same time.
The traditional heating method is to transfer heat from the outside to the heat of the material according to the principle of heat conduction, convection and radiation. The heat is always transferred from the surface to the inside of the material. Inevitably ,there is a temperature gradient in the material, so the heated material is uneven, resulting inthe local overheating of the material.
The microwave heating technology is different from the traditional heating method in that it generates a “internal friction heat” by the high frequency reciprocating motion of the dipole molecules inside the heated body, so that the temperature of the heated material is raised, and the heat transfer process is not required.
The material is heated both internally and externally at the same time. The heating speed is fast and even, and the heating purpose can be achieved only by a fraction or dozens of times of the energy consumption of the traditional heating method.
Industrial microwave equipment prospect :
As the development of modern science and technology , the reliability and practicability of microwave equipment both improved well those years . Professional microwave manufacturer’s manufacturing technology also drive to maturity with lower cost . Many microwave food equipment have characteristic of simple operation ,stable continuous working time and easy maintenance .It has obtained widely attention as one way to realize green technology.
