ABSTRACT:
A cabinet dehydrator for long term preservation of food under close control of time temperature and humidity. Intake air is obtained from the surrounding atmospher and displaced into the dehydrator over electrical heating elements by a blower. This heated air is ported upwardly adjacent the shelves and thereafter normally laterally between the shelves. Baffles are manually set to control the amount of hot air displaced across a given shelf. Humidity controls function to regulate the rate at which moisture is caused to be withdrawn from the food being dehydrated.
