Microwave equipment to promote the development of the pharmaceutical industry
From the 1940s the first microwave available, to the fifties and sixties the successful development of industrial microwave equipment , most countries in the application of microwave energy launched a new " energy revolution movement" universal application of microwave energy to the food , chemical, pharmaceutical and many other areas .
For a long time , China's pharmaceutical processing industry are based on the traditional heating and drying , sterilization methods, such as using hot air , infrared drying for drugs with high temperature and pressure , such as cobalt- 60 for sterilization . They are not only low thermal efficiency , long heating time , the area is not conducive to environmental protection, while sterilization in high temperature about 120 ℃ , time 20 to 40 minutes, the efficacy of their drugs and nutritional ingredients by a certain degree of damage. The use of microwave equipment can give full play microwave drying, microwave sterilization characteristics , we can solve the drawbacks of conventional heating . For example: a well-designed pills microwave sterilization drying machines, machining pills no cracks, consistency, and maintain the original potency , greatly extending the shelf life.
In recent years, microwave equipment in the pharmaceutical drying, sterilization , pharmaceutical extraction has developed rapidly. Meanwhile, microwave vacuum , microwave vacuum freeze-drying technology continues to break , but also to promote the microwave in the pharmaceutical processing industry .
Practice has proved more suitable for microwave equipment of high value products , strict quality requirements , low thermal conductivity , difficult to process using traditional craft materials. As for the excessive moisture of the material , simply using microwave dehydration and sometimes it is not economical . If the microwave and hot air , steam or other methods combined far-infrared , and often will get a "multiplier " effect. If the combination of microwave and hot air drying , air drying rate than the traditional increase more than 8 times . Microwave and far -infrared as a heat source , the material can make use of infrared molecular , atomic vibration energy , the combination , and its drying rate would be 10 times higher than air dried , the rate of curing the material or other heat sources are more than five times faster . This has the scientific, practical combination neither any environmental pollution, and energy efficient, greatly extend product shelf life.
Microwave using high technology to transform traditional pharmaceutical industry, the pharmaceutical industry will open up a new avenue.
