The application of microwave technology in the pharmaceutical industry is mainly in the following aspects: drying and sterilizing of pharmaceutical products such as powder, granules, flakes, and pellets, and rapid drying, insecticidal and sterilization of Chinese herbal medicines. Microwave extraction of Chinese herbal medicine, sterilization of oral liquid, etc.
Microwave Roasting Equipment Wood Processing
The microwave can uniformly and quickly dry the 1-6 cm thick wood board. It takes only ten minutes to dry and does not crack and deform small, and kills the eggs and larvae inside the wood. It can also be glued to plywood or jigsaw. The curing treatment and the bamboo products are dried, inactivated and sterilized.
Microwave Drying Equipment Rubber Industry
Japan with 2450MHz, 5 ~ 10kw microwave heating apparatus of a tire for a heating, with hot air heat vulcanizable 3 to 4 t weight tires heated to the vulcanization temperature; U.S. employed 915MHz, 50kw horn antenna as the radiant heater using program control Rotating scans of large tires have the advantage of uniform heating and a one-third reduction in cure time. The microwave rubber vulcanization equipment developed by our company can be compared with imported equipment such as Japan and Germany in terms of shape, structure, performance and vulcanization quality.
The microwave is a wave having a frequency of 300 megahertz to 300 GHz, and the water molecules in the material to be heated are polar molecules. Its polarity orientation will change with the change of external electric field under the action of rapidly changing high frequency electromagnetic field. The movement of the molecules causes mutual friction effects. At this time, the field energy of the microwave field is converted into thermal energy in the medium, which causes the temperature of the material to rise, and a series of physicochemical processes such as heating and expansion to achieve microwave heating and drying.
Microwave Equipment sterilization
Microwave sterilization is the result of the combined effects of thermal and biological effects of electromagnetic fields. The thermal effect of microwaves on bacteria is to cause the protein to change, causing the bacteria to lose nutrients, breed and survive and die. The biological effect of microwave on bacteria is that the microwave electric field changes the potential distribution of the cell membrane section, affecting the concentration of electrons and ions around the cell membrane, thus changing the permeability of the cell membrane. The bacteria are therefore malnourished, cannot be normally metabolized, the cell structure is dysfunctional, and the growth and development are inhibited. And die. In addition, microwaves enable normal growth and stable genetic reproduction of nucleic acids [RNA] and deoxyribonucleic acid [DNA], which are caused by several hydrogen bonds to relax, cleave and recombine, thereby inducing genetic mutations, or chromosomal aberrations or even ruptures.
Microwave Equipment Extraction
A newly developed new technology that uses microwave energy to increase extraction rate. Its principle is that in the microwave field, the difference in the ability to absorb microwaves causes certain regions of the matrix material or certain components in the extraction system to be selectively heated, thereby separating the extracted material from the matrix or system into the medium. Among the extracting agents with small electric constant and relatively poor microwave absorption capacity, microwave extraction has the characteristics of simple equipment, wide application range, high extraction efficiency, good reproducibility, time saving, reagent saving and low pollution. At present, in addition to being mainly used for environmental sample pretreatment, it is also used in the fields of biochemistry, food, industrial analysis and natural product extraction. In China, there are few reports on the application of microwave extraction technology in the extraction of Chinese herbal medicine.
Thawing of Microwave Drying Equipment
Microwave thawing is to heat the whole frozen product, and the temperature rises from freezing temperature (below -19~-22 C) to near freezing temperature (about 0~-4 C). The microwave thawing equipment has the characteristics of the overall temperature recovery of the frozen material and the small temperature gradient of the return temperature, that is, the temperature uniformity is good and the time required is short, and the temperature rise rate is easy to control. These characteristics make the frozen product thawed to a better state.
1. The frozen product can be heated back to the whole temperature, which reduces the temperature non-uniformity between the thawing layers of the frozen product, and there is no recrystallization phenomenon when the frozen product is thawed by the conventional method;
2, the thawing process takes a short time, bacteria and other microorganisms are not easy to breed and grow.
3. Microwave heating without thermal inertia. The temperature rise rate of the frozen material is controlled by the microwave output power, or the microwave energy supply rate, and is synchronized with each other.
4, the final temperature of microwave thawing is generally selected at -2 - 4 C is appropriate, at this time frozen products without dripping, can also be cut with a knife.
Commercial Microwave Insecticide Sterilization
Microwaves can be used to sterilize insecticides at lower temperatures. It can handle food, medicine, tobacco, wood, etc., and the heating rate is not affected by the thickness and shape of the material.
Industrial microwave dryer
The sulfur in the raw coal appears in the form of pyrite. The pyrite has a higher loss tangent than the coal. Therefore, the pyrite can be selectively heated and reacted with the gas to perform desulfurization. Coal is not affected. The ideal method is to intermittently heat the pulsed wave with a duration of 0.1 second to heat the pyrite ore to a high temperature of 650 °C. This method has good desulfurization effect, does not require expensive catalyst, saves money, has high energy efficiency and low environmental pollution.
Microwave Vacuum Drying Plasma Technology
Microwave plasma technology has been used in semiconductor manufacturing processes for etching, sputtering, vapor deposition, and silicon oxide wafers; it can also be used for surface treatment of metals, alloys, and nonmetals; for plasma spectroscopy, more than a dozen elements can be detected. .
Microwave biological effects are divided into thermal and non-thermal effects. The thermal effect can be treated by microwave physiotherapy, radiotherapy and chemotherapy for microwave treatment; in addition, microwave can be used to heat plasma and thaw frozen organs; microwave scalpel can also be designed to achieve rapid hemostasis and less bleeding.
The microwave measurement has high precision and is suitable for continuous measurement and automatic control in production. Has been widely used in ranging, temperature measurement, thickness measurement and other aspects.
Microwave Drying Ceramic Sintering
Microwave can be used for uniform densification and sintering of ceramics, the maximum temperature can reach 2000 °C, and large-sized fine ceramics can be obtained.
Industrial continuous microwave oven
Microwave has a wide range of applications in chemistry, such as microwave digestion, extraction, hydrolysis, catalytic reactions, etc.
