- a dialysis filter 8 which is shown in FIG. 3
- drying generally takes place from top to bottom, ie. H. After a certain drying time, there is greater moisture in the lower area than in the upper area.
- the microwaves act primarily on the water contained in the dialysis filter 8 as long as it is still present.
