That would just swirl damp air (air + the water vapor from the sieves) round them.You need a flow of fresh relatively dry air to get to the lowest
levels of water in the sieves. I believe those fryers do have vents but not flowing air as that would cool them.
I am wg48 but not on my usual pc hence the temp handle.
Thank goodness for Fleming and the fungi.
Old codger' lives matters, wear a mask and help save them.
Be aware of demagoguery, keep your frontal lobes fully engaged.
I don't know who invented mRNA vaccines but they should get a fancy medal and I hope they made a shed load of money from it.

Would stopping and opening the door for an air exchange every half an hour or so helps, as in the case for conventional oven?
As for conventional oven, mine has a small fan built-in as well, not sure if it's drawing air in or out or just recycling the air inside.

Dried air. For some hours to constant weight. This is how alumina is dried...or at 400C on the stovetop with stirring for the same time; 200C costs
less. It is said 3A sieves should not be heated above 260.

Yes i think that would help significantly.

Experience? |
I was regenerating 3A mole sieves used to dry ethanol. I placed the apparently dry sieves in a large glass cake pan in my kitchen oven at 400F. I
then went into the next room to watch TV. After a while I heard a loud bang! I concluded that the ethanol vapor had exploded and pushed open the
spring loaded oven door, then it self-closed. I continued the drying. |
I did the same thing in my convection/toaster oven. Kaboom haha.
