Closed circuit food dehydrating process

Abstract

The present invention discloses the special and unique process for a Closed Circuit Food Dehydration Process wherein the uniqueness of the present invention lies in the combination of chilling recirculating air within an enclosed chamber containing the food to be dehydrated to extract and remove latent moisture from within the recirculating air and subsequently heating the selfsame recirculating air to increase the dehydrating efficiency of the Closed Circuit Food Dehydrating Process. An additional feature of the present invention is the recirculation of the air within the enclosed chamber without the communication of air from without the enclosed chamber during the dehydration process.

I claim: 
     
         1 . A process for dehydrating a moisture containing food comprising:
 a food dehydration chamber wherein the food to be dehydrated is placed, with said food dehydration chamber sealed from the outside atmosphere during normal operation;   an air duct which solely communicates with said food dehydration chamber such that the air duct allows the passage of air through said air duct from said food dehydration chamber and returns the air to the food dehydration chamber without the communication of air to the atmosphere without the air duct or the dehydration chamber, effecting a closed system;   a fan contained within the air duct for the purpose of movement of air through the air duct;   an air chilling unit contained within the air duct for the purpose of removing moisture in the form of condensation from the air to effect dehydrating the air;   a moisture condensation collector for the purpose of collecting and segregating from the air the moisture in the form of condensation from the said air chilling unit;   an air heating unit contained within the air duct for the purpose of heating the air.
