Abstract
A high density, single pass heat exchanger (26) is provided which is designed for drying products such as bakery wastes, alfalfa, peat moss, wood or similar fibrous products. The exchanger (26) has a series of circumferentially spaced, inwardly directed heat transfer sheet metal flights (48) presenting a central flight-free zone (74), together with a series of baffles (282-288) in axially spaced relationship along the length of the exchanger (26). A number of annular deflectors (294-298) are mounted within the exchanger (26) between adjacent baffles (282-288), such that the baffles (282-288) and associated deflectors (294-298) cooperate to cause the material being dried to follow an essentially serpentine, generally helical path (300). The exchanger (26) is capable of efficiently removing moisture from wet products by virtue of the fact that the diameter (R) of the exchanger (26) to the diameter (r) of the internal flight-free central zone (74) is from about 1.4-2.4. The disclosed exchanger design may be used for updating existing three-pass and single-pass dryers, or for the fabrication of new systems.
