This machine could reduce about 10 times cost and improve production efficiency 10-15 times than before. - details see: https://www.machineto.com/microwave-vacuum-drying-equipment-for-biological-product-10306241

Main application:

This machine is used for low-temperature drying of heat sensitive Chinese medicine solid preparations. It can also be used as vacuum concentration equipment. Its drying speed is very quick and it can improve the quality of products dramatically. It characterizes high efficiency, even heating, easy to control, and convenient installation and maintenance etc. It is mainly applied to the drying, heating, sterilization and ripening of medicines, biological products, agricultural product and by-product. Specially, it is excellent in the drying effect of various pills and granulated materials. In addition, microwave low temperature vacuum drying equipment still has the functions of sterilization and disinfection. It possesses power linearity adjustable, intelligent control, and environment & temperature controllable. Finished products are safe and healthy, and their quality guaranteed period can be prolonged.

Operating principles:

During the operation, first microwave is produced by microwave signal generator and then transferred into microwave oven by energy feed-through. At the same time, materials are conveyed into the heating container by transmission system. Here, water in the materials is heated and vaporized by the action of microwave energy and water vapor is vented by dehumidifier, so as to attain the purpose of drying. Bacteria in the materials are killed under the biological effect and heating effect of microwave, which are generated under the action of microwave electromagnetic field. Because microwave can directly effect on the materials, it brings on low drying temperature, rapid speed, and minimal loss of effective elements of medicines.

Structural features:
Heat sensitive materials can be dried, dehydrated, condensed quickly under the normal temperature condition. Their dehydrated temperature is controlled under 40º C. It makes features of infrared measurement of temperature, digital timing, power adjustable, intelligent control, easy operation, even heating, and energy saving 50% in power consumption compared with general equipments. Besides, it is also used for the drying, dehydration, and condensed treatment of many oxidizable materials. Materials can be processed three-dimensional rotation and area of spreading materials is big. There are different grades of equipments to be selected.
