Dehydrator
Heat
Transfer

dehydrator heat transfer formula

A furnace combustion - gas expansion in
   the furnace

B the expansion of water vapor after product
   is introduced

C heat transfer media - the remaining volume of
   air and natural gas that have been burned














THE SCIENCE
BEHIND DEHYDRATION AND HEAT TRANSFER
The Volumetric Analysis of Dehydration chart illustrates the volume changes of the gas, air and moisture as they pass through the dryer as one pound of water evaporates. The vertical axis represents volume and the horizontal axis represents time as well as temperature.



EXAMPLE :: Actual Heat Req = 1750 btu/1 Excess Air = 200%
