ABSTRACT:
A dryer for removing vaporous substances from products in which the product sequentially passes beneath an array of ventilating nozzles and an array of infrared heaters. The dryer includes a generally rectangular frame forming a central drying zone having an infeed end and an outfeed end. The array of ventilating nozzles is positioned at the infeed end of the drying zone in order to quickly remove surface moisture from the product. The downstream array of infrared heaters removes residual surface moisture and moisture beneath the surface of the product. The ends of the heaters project into a pair of inlet ducts extending along opposite sides of the frame so that the ends of the heaters are cooled by air flowing through the ducts. Air flows through the ducts from an inlet near the outfeed end of drying zone to a blower manifold where the air is mixed with recirculated gases from the ventilating nozzles and air entering the infeed end of the drying zone before being conveyed to the blower. Each of the heaters is covered by a semi-cylindrical reflector having their edges spaced apart from each other to form ventilating passages therebetween. Air flows through the ventilating passages located between the infrared radiation elements onto the product in order to remove a boundary layer of vapor which would otherwise absorb infrared radiation. A flexible belt extends beneath the drying zone and continuously carries product end beneath the array of the heater elements and ventilation nozzles.
