Medicines Microwave Drying

Medicines Microwave Drying

▪ Dehydration quickly: The use of microwave thermal effect and non-  thermal effect, low temperature drying and sterilization, microwave   energy radiation directly to the drug, the drug internal temperature,   pressure, speed up the transfer of bound water molecules, proce-  ssed items of moisture to evaporate gradually outward, at this time   in microwave devices again with proper hot air, the rapid evaporation   of moisture away. 

▪ Energy-efficient: In order to ensure the quality of products, should   strictly control the air temperature, humidity and flow, the use of mi-  crowave drying treatment chemicals not only high quality products,   and can greatly shorten the drying time and save a lot of energy, ec-  onomic benefit is obvious. 

▪ Versatility: Microwave is done in and out of the heating of the drug,   and it has a certain swelling effect on the drug, so it is more benefi-  cial to the absorption of the drug. Drugs by microwave sterilization,   generally only a few seconds to a few minutes. Better maintain the   organic nutrient content of original drug and nutrition products, im-  prove the curative effect. ▪ Applicable materials: It is widely used in the drying and sterilization of pills, tablets, powder, medicine particles, etc.

Principle of Microwave Sterilization Drying

Microwave sterilization is the result of the combination of thermal and biological effects of electromagnetic fields. The  thermal effect of microwaves to bacteria is to make proteins change, causing bacteria to lose nutrients, reproduce and  survive conditions. The biological effect of microwave on the bacteria is microwave electric field change in the cross section  of the cell membrane potential distribution, influence the membrane surrounding electrons and ions concentration, which  change the membrane performance, fully bacteria so malnutrition, cannot normal metabolism, cell structure function disorder,  growth is restrained and death. In addition, the microwave can make normal bacteria growth and stable genetic breeding of  nucleic acid RNA and DNA, DNA is made up of a number of hydrogen bonding is flabby, faults and restructuring, and thus  induce genetic mutations, or chromosome aberration and even rupture.
