Purpose
It is mainly applicable to low temperature fast drying for Chinese medical concretes, Chinese medicinal materials, Chinese/western medicines and health care products as well as heat sensitive materials in such fields as food, biological engineering, chemistry and material.
Principle
Under vacuum condition, the microwave reacts directly with materials to heat the inside and outside of materials at the same time, without the need of transferring heat to materials via air convection or conduction. Material trays are fixed on the bracket. Microwave directly radiates materials. Materials trays rotate slowly inside the cabinet to evenly heat the materials in all trays, with small temperature difference. This process realizes fast low temperature drying of materials, and overcomes the disadvantages of traditional vacuum drying, including low speed heat conduction, low efficiency and large temperature difference etc.Â
Features
1.Stepless adjustable microwave power ensures evenness of drying effect and achieves the aim of saving energy during operation.
2.Many kinds of control modes are available for choice.Â
3.Adopt industrial strength 1500W self-cooled transformer, designed for continuous operation, with strong and stable power. Â
4.Adopt industrial strength 1050W magnetron and direct water-cooled technology to realize long continuous operation, with good performance and controllability.
5.Vacuum system adopts water-ring vacuum pump and imported machinery sealing. Suction pressure can reach 33mbar. Stepless vacuum degree adjusting mechanism can adjust the vacuum degree according to different materials to realize vacuum low temperature drying. Â
6.Infrared temperature measurement and control system can accurately measure the temperature of materials in trays in good time, ensure accuracy of temperature control, and facilitate improvement of product quality.Â
7.Material feeding/discharge positioning device ensures material trays always stop at material discharge port to facilitate operation, cleaning and reduce labor intensity.Â
8.Rectangle microwave guiding assembly unit is developed to have small wave-guide stationary wave, which can better match with magnetron to ensure its high output efficiency.Â
9.With human-computer interface operation system, the equipment can be started by inputting basic technological parameters. Microwave power and drying time can be calculated automatically. Automatic operation ensures that materials can be discharged when operation time is over.
10.Electronic monitoring system and vacuum sight glass system are installed to monitor and view the characteristics and drying degree of materials in real time, and facilitate control and operation.Â
11.Monitor the flow rate and temperature of cooling water in cooling system in real time to avoid damaging magnetron due to cooling water pipe blockage, too high temperature of cooling water.Â
