QUESTION:I have an Ender (made in Germany) fluid bed roaster (220 volt) that I bought
many years ago from a place in California that no longer handles this item.
With the roaster came a pack of paper filters whose purpose was to collect
the chaff and so stop it from blowing all over the room during the roasting
process. As I have run out of these filters I'm looking for a new source or
a suitable substitute. In the past I've tried the following: tissue paper
(both one and two ply), paper towel (again both one and two ply), Melitta
coffee filter, aluminum screening. None of these substitutes worked- either
the substitute was too fine to let enough air pass through (in which case
the lid of the roaster would pop off blowing chaff all over) or it was not
fine enough and chaff blew through the substitute filter and again all over
the room. I'd really like to find a source for the original filters, but I
have no idea where to turn. Thanks in advance for any help you can offer.
ANSWER: The Lennox furnace folks made some furnaces in the past that use
something called a basket filter. Instead of just changing a cartridge-like
filter you get to take stuff apart and replace the filter material (lucky
me).
In the past this material has been a blue fiberglass like substance about
3/4" thick but lately there have been a couple of much thinner filters
available. 3M makes the expensive one and there are some knock-offs
around, they are white and less than 1/4" thick. A recon of the furnace
filter section of Home Depot or Canadian Tire etc. should allow a look
at the stuff. If it looks suitable a lifetime supply won't be too much $.
I used some of the trimmed off excess to bolster the air filter on my
air compressor.
