ABSTRACT:
A commercial laundry dryer with a perforated drum for the laundry mounted in a housing to rotate on a horizontal axis and the drum is of the full width and length of the housing to maximize the load size for the floor space occupied by the housing. The fuel-fired burner is mounted below the drum and faces upward with a deflector preventing the flame from contacting the drum. The fan for circulating the drying air is mounted above the drum as are dampers for selectively causing the drying air to be recirculated to the burner and drum or exhausted after a single pass and a lint collecting and discharging arrangement. The drying air is introduced into the bottom of the drum at the center, passes upwardly through the laundry load and out through the top of the drum near the axial ends.
