ABSTRACT:
The energy required for forced air drying fruits such as raisins, grapes, prunes, etc. is decreased by from 25 to 50 percent by substituting trays of molded thermoplastic resin for the wood trays now in use. Part of the increased efficiency comes from better contact of the air with the fruit and the balance of the improvement comes from the elimination of water absorption which has heretofore been present in the wood trays. The plastic trays also have much longer life.
