Drained ice is more efficient than floating ice at flash cooling. Try
putting a hole in the bucket so you don't have liquid water in it. It is
insulating the hose from phase change of the ice and thus the flash cooling
efficiency (like a wet suit keeps you warm). And put a refrigerated air
drier ahead, so you're not wasting time removing latent heat and sputtering
liquid condensate.



We had a drier so condensation was not a problem.

I am confused though why you say drained iced would be more efficient than a
water bath of ice water.

Water is a much better conductor of heat than air, so wouldn't more heat
tranfer from the hose into the bucket of ice water rather than a bucket of
ice air? I know that if I stuck my hand into ice water, it would be much
colder than sticking into a bucket with ice cubes.

Please un-confuse me.
