Concept of a new device - step 2

After selecting a new refrigerant, it is time to redesign the refrigeration system, i.e. select the appropriate components, including the shape and length of the evaporator. The FrostWave team decided to move from an external evaporator (coil) to a microchannel evaporator located inside the chamber. In parallel with these activities, steps relating to a method for applying microwave heating have been taken.

Two concepts in which the microwave emitter is placed on the top of freeze-dryer have been proposed, and:
1) the inner chamber was left
2) the inner chamber wass removed and the evaporator is separated by a membrane

Of course, in the new device with microwave heating, you cannot forget about the appropriate selection of materials from which the inside of the freeze dryer will be made.
The concepts are presented in the figure below:
