Emerson: Dry conveying for food packaging
See it at PACK EXPO, Booth #6132! The new System Plast NG Evo conveyor chain from Emerson's Power Transmission Solutions business features a proprietary, low-friction FDA-approved thermoplastic resin for dry conveying in food packaging applications, and provides a higher breaking load, greater elasticity, lower coefficient of friction, and much greater abrasion resistance than its predecessor.
Significantly expanding options for dry conveying to meet sustainability and water conservation goals, NG Evo chain’s proprietary thermoplastic resin is suitable for high-speed and dry-running applications, where it lowers power consumption and noise, andincreases thebelt’s wear life.
The companion Nolu-S wear strips and guides enable reduced-lubrication or lubrication-free, high-speed conveyor operation. They are made of a unique resin with a solid lubricant that dramatically reduces the coefficient of friction. Nolu-S helps reduce noise, energy consumption, squeaking, and chain pull/belt fatigue. The combination of NG Evo chain and Nolu-S wear strips can reduce a conveyor’s energy requirements by up to 30%, with service life as much as five times greater, according to the company.
All of the physical properties of the original NG chain have been enhanced to meet specific challenges in food processing applications. In addition, beverage handling conveyors are typically lubricated with soap and water that uses two to three times more water than goes into the finished product. There are obvious costs for this, but the hidden cost for wet conveyor is in the slip hazard, pumps, leaks and premature failure of bearings, sensors and other conveyor components.
System Plast NG Evo chain is an advanced, low-friction concept that can eliminate or greatly reduce wasteful water-and-soap lubrication typically used on food and beverage conveyors. It also reduces the costs and energy for water reclamation/treatment, and eliminates the wear paste buildup, noise pulsation, and hygiene issues caused by mineral-oil-based dry lubricants.
Plant engineers can determine their own potential conveyor cost savings using a new mobile app that calculates cost reductions from various choices of motors, drives and flat-top conveyor chains, as well as quick changeover guide rails and elimination of water/soap lubrication. The FREE mobile app can be obtained from the mobile app page at www.emerson-ept.com.
