Kwsg Tunnel Type Microwave Sterilizing Dryer/ Food Vegetable Drying Machine
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
Drying principle: Under the action of continuous fast-changing high frequency electromagnetic field, the polarity orientation of materials will change with external electric field when passing specially-made conveying belt, resulting in movement and mutual friction effect of molecules inside materials. At this time, microwave magnetic field energy is changed into thermal energy to increase the temperature of materials. Continuous magnetic field energy is transformed into thermal energy which can dry materials quickly at low temperature.
Sterilizing principle: microwave sterilizing utilizes thermal effect and non-thermal effect to jointly kill microorganisms.
1.Segmental stepless adjustable microwave power ensures evenness of drying effect and achieves the aim of saving energy during operation.
2.Self-cooled industrial strength 1500W transformer is designed for continuous operation, with strong and stable power.
3. Grasp assembly technology of direct water-cooled industrial strength 1050W magnetron to realize long continuous operation.Â
4.Adopt large air flow centrifugal fan, adjust dehumidifying speed of air flow regulating device according to different materials.
5.Infrared temperature measurement and control system can accurately measure the temperature of materials in good time, ensure accuracy of temperature control, and facilitate improving product quality.
6.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.
7.Conveying belt adjustment tensioning device adopts electronic rectification technology to ensure stable operation of material conveying belt.
8.Install electronic monitoring device and vacuum sight glass hole (dual structure) to view and monitor material state in real time, grasp its characteristics and drying degree and better control operation.
9.The monitoring of cooling water flow rate and temperature can completely avoid insufficient flow rate resulted from outlet pipe blockage, magnetron damage caused by too high water temperature.
