Microwave heating equipment features:
Microwave heating device has a fast heating, the heat loss is small, easy to operate, not only can shorten the processing time, increase productivity, reduce production costs, but also can improve product quality. Compared with conventional heating, microwave heating has the following characteristics:
A microwave heating uniformity, fast:
With normal methods of heating heats the surrounding environment to the heat radiation or by hot air convection to the first surface of the object is heated, and then through heat conduction conduction inside the object. Low efficiency of this method, the heating time is long.
The biggest characteristic of microwave heating, microwave heating products both inside and outside heats up evenly and will not cause "coke in the unfamiliar," the half-cooked phenomenon, will help improve product quality, and because "both inside and outside heating" greatly reduced heating time, high heating efficiency, help to improve product yield. Microwave heating inertia is small, can achieve rapid control of temperature down, is conducive to the amount automatically controlled continuous production.
2, selective heating
The heat generated by microwave heating, and the loss to be heated has a close relationship. The dielectric constant of a variety of 0.0001 to 0.5 range, the microwave absorption capacity of various objects is very different. Generally the dielectric constant of the medium it is easy to use microwave heating, the dielectric constant is too small, it is difficult to use microwave heating medium. This is the object of selective microwave heating characteristics.
3, the control and timely, responsive
Conventional heating methods such as steam heating, electric heating, infrared heating, etc., to achieve a certain temperature, will take some time, in the event of failure or stop the heating when the temperature drops again a long time. The microwave heating can be rapidly within a few seconds the microwave power to the desired value, heating to an appropriate temperature, to facilitate automated and continuous production.
4, strong-field temperature
Medium unit volume absorbed microwave power is proportional to the square of the electric field strength, so that you can at very high field strength
Under the processing object in a very short period of time up to the desired processing temperature. High field strength but also the quality of the product is not affected, resulting in bactericidal effect.
5, the microwave heating penetration ability
Far infrared heating frequency than higher frequency microwave heating, the heating efficiency is reasonable to be better, but it is not true, there also exists a penetration concept. Despite many advantages far infrared heating, the application is relatively broad, but the object penetration capability, far less far-infrared microwave. What is the ability to penetrate it? Ability to penetrate through to the electromagnetic waves inside the medium is the ability of electromagnetic waves from the surface into the medium and in its internal propagation, because energy is constantly being absorbed and converted into heat energy, it
With the depth to carry the heat on the surface of the medium distance decay exponentially. Penetration depth and the wavelength of electromagnetic waves of the same order of magnitude, in addition to a large object, in general, can be heated table. And the wavelength of far infrared heating is very short, poor penetration when heated in the far infrared radiation, a thin layer of heat only the object, but mainly by heat conduction to the inside, so that not only the heating time is long, and likely to cause uneven heating . According contrast, the penetration of microwave heating than the far-infrared heating more strong.
6 clean, non-polluting
General industrial heating equipment is relatively large, covering more than the ambient temperature is relatively high, the operating conditions of poor labor and strength. The microwave heating, small footprint, avoid high temperature environment, labor conditions have been greatly improved.
