Pamela, you do not provide enough information to evaluate "effective" as it
pertains to drying. In any case, removing water from the product at low
temperature will require a relatively expensive refrigeration system but it
can be designed to be "effective".
Refrigeration systems in smoking ovens are usually installed for "cold
smoking" products but can be used in hot smokers during the process to
create a "zero emissions" system. In some cities air pollution regulations
require "zero emission" - no smoke ejected from the process. The
refrigeration system is designed to dehumidify the air which is reheated and
recycled.
When refrigeration is used in cold smoking processes there is the added
advantage that the length of the process can be extended without risk of
growth of pathogenic bacteria. Typical processes operate at temperatures
around 10 to 15 C.

Dear List Members,
We are having some quality problems in our smoking plant and one of the
maining problems is that we don't have a smoker that has the ability of
drying before smoking. A friend proposed me a drying system in a cold
chamber (0º C). I have listened that other plants use this system, but I
would like to know more information about the parameters managed in this
process. It's really so effective as drying with air at 25-30º C with 60%
R.H. during 2 to 3 hours?
Any information on cool drying would be much appreciated.
