Leybold will present its100% oil-free screw type vacuum pump NOVADRY for food processing and packaging at the international trade fair for the meat industry IFFA in Frankfurt am Main from 04 to 09 May 2019 in hall 11, booth A41.
The completely newly developed, oil-free screw vacuum pump ensures significantly greater safety and efficiency in food and packaging processes.The demands placed by manufacturers and consumers on the quality, shelf life and resource efficiency of food and packaging processes are constantly increasing. This applies even more to such perishable products as for example meat or fish. Vacuum is considered as an enabling technology, contributing significantly to optimizing these processes. Leybold developed the Novadry as a new 100% oil-free, air-cooled pump. No oil, less effort Many users in meat processing and packaging cannot actually tolerate vacuum pumps emitting oil. The pump is a 100% dryfollowing hygienic criteria. This increases safety in applications such as tumbling, filling, vacuum packaging and thermoforming. Oil-free vacuum pumps have a lower cost of ownership, as less maintenance and spare part changes are required. Leybold has transferred components and principles from other vacuum pump series to the pump, including the bearing structure and the belt drive, which synchronizes the rotors. Normally, dry pumps are water-cooled, but the Novadry is air-cooled. This aims to reduce operating costs by simplifying the installation and commissioning. Broad range of applications The Novadry, however, achieves its performance over the entire pressure range and life cycle. This makes it suitable for simple applications, which emit low amounts of humidity, such as packaging of cold products. Moreover, the pump is also perfectly suited for more demanding processes with large amounts of water vapour, for example when hot meals with temperatures of up to 95°C have to be quickly cooled down by evaporative cooling.
