Abstract: The structural characteristics and design points of continuous microwave pill drying equipment are expounded. It is determined that the dehumidification system design of microwave drying equipment adopts the air inlet at the bottom of the outlet of the equipment and the wind at the top of the inlet end, so that the cooling air is “S” inside the equipment. Type of motion; and optimized the equipment structure by means of finite element analysis software.
The results show that the electric field distribution varies greatly in different positions of the microwave drying chamber; the frequency is greater than 1. 5 GHZ microwave can have a certain resonance effect; the drying chamber with trapezoidal waveguide port, and the two waveguides are arranged vertically and horizontally, the electric field distribution in the drying chamber is stronger and more uniform; the most suitable position of the drying bed arrangement is It is about 200 mm from the bottom.
