Drives for food & beverage machinery Low and high aseptic Lenze ideas in motion
A wide range of Lenze drive products are suitable for use in food & beverage machinery, also other equipment in arduous environments. Generally these products fall into one of two groups: Low Aseptic for areas where moisture will be present. Typical product features are a high enclosure (IP65, IP66), food quality oils in gearboxes, nickel plated surfaces. High Aseptic for washdown areas where products may have stainless steel construction, minimum dirt traps, no paint finishes. The essential requirement is to cut out maintenance and downtime caused by ingress of moisture or surface corrosion. Planetary geared servo motors in stainless steel IP65 Inverters Stainless worm geared Coupling & connections in stainless steel
Within the food & beverage industry, drives may be needed in food areas for the production of: meat & poultry beverages bakery diary produce seafood fruit & vegetables confectionery tobacco A production line may typically consist of a mix of nonaseptic, low-aseptic an high-aseptic areas.
