Abstract: This invention relates to a dryer particularly suitable for particulate matter having an endless conveyor in the form of a polyester fabric screen wherein the endless conveyor is normally flat but is given a trough-shape as it passes within the dryer to contain the particulate matter. Means are provided for moving the fabric screen through the dryer including an open support disposed beneath the fabric screen. Stationary, elongated trough-forming means within the dryer pick up the sides of the fabric to form and maintain the trough-shape, and stationary baffle plates within the dryer engage the trough-forming means to direct the flow of drying air through or against the matter being conveyed.
