The apparatus particularly useful for the dehydration of organic materials, includes a drying enclosure (100) to receive and contain materials to be dehydrated, a cooling section (200), with a first stage cooling coil (202) and a second stage cooling coil (204) to remove moisture from a frying fluid by condensation, a heating section (300) with a first stage heating source (302) and a second stage heating source (304) controllable for selecting the amount of heat output therefrom, to raise the temperature and lower the relative humidity of the drying fluid and a drying fluid handling system to convey the drying fluid in a closed loop through the sections of the apparatus. The process of the invention includes the general steps of heating a drying fluid, passing the drying fluid over the materials to be dried, cooling the drying fluid to condense moisture, heating the drying fluid to elevate its temperature and reduce its relative humidity, and reintroducing the heated drying fluid to the process loop to be recirculated through the apparatus until the desired degree of dehydration has been achieved. |
