Ohio-based Paxton Products claims its PowerDry system has been designed as an easy-to install replacement for plastic comb or air jets and other common pneumatic blow devices. Processors use dryers to reduce moisture in products that are to be packaged, as humidity will reduce the shelf life of the food and lower consumer appeal. They also use air flows to remove debris. Packaging is also dried to allow easier sealing, labeling and secondary packaging. The PowerDry generates high velocity airflows from a centrifugal blower that develops pressure from a three horse power motor, the manufacturer claims. The airflows are carried by US Food and Drug Administration compliant hoses to a six-nozzle air tube that delivers successive hits of compacted air to a targeted area. The design eliminates the possibility of contamination caused by oil or the build up of scale, claims the company. The air tube is held in place by a fully adjustable, stainless steel, mounting arm. Field tests showed the dryer returned an average of about 80 per cent savings in energy costs, while providing comparable or improved drying in every application, claims Paxton. Depending on operating hours, the return on investment from energy savings can be less than one year, the company claims. The entire system is capable of being washed down during changeovers. Paxton is a manufacturer of air-related products including compressors, blowers, air knives and drying systems.
