Application of microwave in chrysanthemum insecticide and mold

Posted on: 四月 12th, 2017 by langfeng No Comments

drying equipment
Chrysanthemum in the process of storage and transportation of insects, black tea in the Ottawa reactor process often occurs insect pollution phenomenon. In the past, commonly used drugs fumigation insecticide method, but there is the problem of drug residues. The insecticidal effect of insects in chrysanthemum is closely related to the dielectric properties of chrysanthemum and insects. When the water content of chrysanthemum is less than 12%, it is beneficial to enhance the insecticidal effect.
Chrysanthemum in the processing and storage easily damp moldy and reduce the quality. Experiments proved that microwave technology on chrysanthemum fungi has an excellent killing effect.

Characteristics of Industrial Microwave Equipment

Conventional heating such as flame, hot air, electric heating, steam and other heating, are the use of heat conduction principle of heat from the outside of the object into the inside, and gradually increase the center of the object temperature, known as external heating. The process to make the central part of the required temperature, take some time, while the need for a higher external temperature; poor thermal conductivity of the object takes a long time. Industrial microwave equipment is to make the object itself to be heated objects, called the overall heating method, do not need heat conduction process, so in a short time to have a uniform heating. This feature allows the heat conduction of poor material in a short time to be heated and dry, the energy utilization rate is improved, but also can make the size of the furnace than the conventional heating furnace is smaller.

Microwave drying technology

Posted on: 一月 11th, 2017 by langfeng No Comments

Microwave drying is different from the traditional drying method, the direction of heat transfer and water diffusion in the same direction. Compared with the traditional drying method, it has the advantages of large drying rate, energy saving, high production efficiency, uniform drying, clean production, easy realization of automatic control and improvement of product quality and so on, and thus more and more attention is paid to various fields of drying. As early as the 1960s abroad on the microwave drying technology on the application and theory of a large number of studies in recent decades has been further developed. China’s microwave drying technology research started late, compared with foreign countries have a certain gap, but also achieved good results, there are many research and application results. China’s microwave drying technology is now used in the food industry, chemical materials, pharmaceutical industry, mining industry, ceramics industry, laboratory analysis, wet natural rubber processing and so on.

Microwave Tube Furnace

Microwave is a frequency in the 300MHz-300GMHz, the direction and size of the cyclical changes over time with electromagnetic waves. This kind of electromagnetic wave is not absorbed and transmitted by metal, can only be reflected; can penetrate glass, ceramics, plastic and other insulating materials without consuming energy, can be polar molecules (such as water molecules, proteins, fats, nucleic acids, carbohydrates, etc. ) Absorption and then into a significant feature of thermal energy.

sintering materials by direct microwave heating

Posted on: 七月 22nd, 2016 by langfeng No Comments

Various fundamental problems are usually encountered when sintering materials by direct microwave heating. Most of the research on material processing by microwaves is based on conventional low-frequency (2.45 GHz) microwave applicators. However, such applicators do not couple microwave power efficiently to many ceramics at room temperature, and poor microwave absorption characteristics make initial heating difficult.


Thermal instabilities may occur, which can lead to the phenomenon of thermal runaway; i.e., the specimen overheats catastrophically. The temperature gradients inherent in volumetric heating can lead to severe temperature non-uniformities, which, at high heating rates, may cause non-uniform properties and cracking.

The microwave sintering in the dental porcelain research

Posted on: 六月 24th, 2016 by langfeng No Comments

microwave sintering

Some people researched process and properties of nano all-ceramic dental materials by using microwave technology.

The results show that microwave sintering high-purity α-Al2O3 in all-ceramic insulation 1 600 ℃ in 10 min, can reach 99.0 percent relative density; compared with conventional sintering, the sintering temperature decreases, sintering time is shortened considerably, before and after sintering grain size is small. And designed to help heat insulation combine to successfully carry out all-ceramic sintering Al2O3, high heating efficiency heating system thus established, simple structure, easy to operate.

Grain size of microwave sintering of all-ceramic material sintered little change before and after the sintered body uniform and compact, this high-performance all-ceramic dental materials, especially dental ceramic materials for the development of nano provides an important means of technology.
