Abstract
An improved industrial dryer adapted for more efficient, quieter and safer operation. The dryer blower has a relatively large size blower wheel adapted for generating high volume air flows at substantially reduced noise levels so as not to disrupt the work environment nor necessitate that workers wear ear protection. The blower is mounted on a pivotal door of the housing for easy access and an adjacent air feed cone is mounted for selective adjustable positioning into axial relation with the blower wheel for efficient air distribution. The dryer includes a burner adapted for generating a multi-leg, relatively short length discharge flame for enhancing fuel combustion and maximizing surface area over which air passes and is heated as it is drawn to the tumbler of the dryer.
