Concept of a new device - step 3

Recently, the activities of the project team have focused on developing the concept of a prototype of a freeze dryer equipped with microwaves and a new cooling system.
The proposed ideas for a new device geometry are based on the following modifications:
- internal evaporator with microwave membrane
- the use of the position of the zigzag-shaped shelves

The proposed methods of introducing microwave technology are as follows:
- classic waveguide input
- classic waveguide input with a fan
- semi-permeable internal waveguides
