Some preliminary investigations on dehydration of fruits and vegetables with infrared energy

Abstract

1. 1. This paper deals only in a preliminary nature with infrared radiation in the dehydration of fruits and vegetables. 2. 2. Based on the studies thus far carried out with: apples, beets, carrots, celery, potatoes and spinach, drying lamps of the type used in these preliminary investigations seem to provide a reasonably practical answer to the dehydration problem. 3. 3. The flexibility, ease of control and amount and intensity of energy required during dehydration are three factors highly significant. 4. 4. Infrared radiation, as applied to the dehydration of fruits and vegetables, may probably be satisfactorily applied to the dehydration of meats. 5. 5. Radiant energy as obtainable from the drying lamps offers a vast field of application in agriculture.
