NZ food industry benefits from leading-edge portable drying technology
Drying Solutions Ltd founder Robert and wife Paulette Barnes with their Rexmoi dryer, a unit that services the food and pet-food industry. When Robert Barnes was asked by a friend to build a dryer to dehydrate macadamia nuts 25 years ago, he never thought it would be the start of his own drying machine business. Robert, an electrician and refrigeration engineer by trade, set up his own refrigeration and air-conditioning company in 1989, attracting Port of Tauranga as one of his clients. Since 1995 he has also been using his skills to develop highly innovative Rexmoi Dryers. He sold the refrigeration and air conditioning business five years ago to focus solely on Drying Solutions Ltd. Now Robert is gearing up to exhibit a Rexmoi dryer, at his fourth Foodtech Packtech show next month. Robert says he is proud that his dryers enable people to turn ordinary products, in some cases waste material, into high-quality, high-value finished goods for the ultimate benefit of New Zealand. Rexmoi dryers use a refrigeration system, rather like a heat pump, to create a warm, dry enclosure where the products are dried. Warm, dry, filtered air flows over the product to remove the moisture which is then condensed and drained out through a small pipe. The product is laid out on stainless steel trays mounted on trolleys for easy handling. Several different types of tray are available to suit the various products such as wet slices, nuts, raisins, pet-food and bushy material. The dryers use much less energy than other drying systems and are totally enclosed so no smells or gases are emitted into the atmosphere. They are covered by several patents and trademarks. The drying process is controlled by a programmable controller which Robert sets in conjunction with the client to provide an optimum drying […]
