PRINCIPLE Band dryer is composed of one perforated conveyor supporting a layer of product, passed through by process gas. Dryer is constituted by several modular sections with independent heating and air circulation systems. Process gas is blown whether downward or upward or in a combined arrangement in order to improve homogeneity of treatment. Cooling section can be foreseen after drying zone. Band dryer can be fitted with accessories (feeder, spreader, cleaning devices, etc.). It is the most appropriate equipment for fragile, sticky, pasty products or products requiring long and accurate residence time. ADVANTAGES OF THIS TECHNOLOGY Energy saving due to gas recycling Highly homogeneous treatment Adjustment of temperature, gas velocity and direction in each section Multiple processing in one single equipment Versatility of processes and applications Accurate adjustment of residence time Possibility to add accessories for mechanical action on product MAIN APPLICATIONS Extrudates, beads, granules, crumbs, paste, pet food, sliced vegetables, prills, flakes, etc. MAIN PROCESSES Drying, calcining, cooling, cooking, toasting, dehydration, etc. PILOT TEST LABORATORY For determination of band dryers parameters, using a batch lab scale pilot. Possibility of equipment rental. The Band Dryer is the most appropriate equipment for several fragile, sticky or hard to dry products. Principle of a Band Dryer: The product to be processed will be distributed in an uniform layer on the band conveyor by means of a suitable feeder i.e. oscillating spreader, vibrating distributor, extruder, spreading screw, etc.
