Patent number: 4945657Abstract: An improved multiple-pass drum dryer (12) is provided which includes an enlarged, flighted premixing zone (65) including a frustoconical, converging transition section (68) leading to an innermost passageway (138) of a concentric multiple-pass final drying section (24).

In this way, product is moved along a first region (66) of the premixing zone (65) at a relatively low average speed so that the initially wet product is proximally exposed to heated gases emitted from a burner for a maximally effective time period. The product then experiences a relatively rapid acceleration in the transition section (68) due to negative pressure from a downstream fan and decreasing cross-sectional area in the transition section (68).Type: GrantFiled: August 23, 1989Date of Patent: August 7, 1990Assignee: Productization, Inc.Inventors: Donald E.
