The Director of Engineering at G. C. Evans, Jason Jones, made some important observations regarding the critical nature of drive dependability, as well as ease of maintenance. “Drives on our pasteurizers have to be, in essence, failure proof. If this pasteurizer stops, our customer loses product, and that simply cannot happen. That’s why we trust NORD drives.”
NORD drives are standard on all G.C. Evans products, including the smaller drives used on conveyor systems which bring product to and from the processing unit. NORD Helical-bevel integral gearmotors with keyed hollow bores are used for their infeed drives, and NORD MINICASE® units drive the dynamic transfer service belts.
During a site visit, two gigantic pieces of equipment were nearing completion. The first was a cooling tunnel that moves 20,000 jars of jam weighing a total of 50,000 lbs. with a single NORD CLINCHER™ gearmotor operating at a 2500:1 gear ratio and moving at 0.6 RPM. This drive incorporates a multitude of options that are necessary for the sanitation demands of food processing applications, including protective coating, filling with food grade mineral oil, AUTOVENT™ and an oil sight glass.
The second was a pasteurizer intended to pasteurize cans and bottles of fruit juices. The conveyor belt is 16’ wide and 84’ long moving at a pace of 45 minutes of package transit time. Here again, one NORD CLINCHER™ integral gearmotor is used, this one operating at 0.7 RPM. Jason Jones states, “For the pasteurizer, we also have GRIPMAXX™ bushings on the driving roller. This roller is removed every few years to service the bearings and for maintenance. A more traditional key-way-secured bushing may be quite problematic, since fretting and corrosion make it very difficult (and sometimes expensive) to remove. With the GRIPMAXX™, the hollow bore simply collapses on to the shaft. Removal of the shaft is then grab-a-wrench simple.”
Great customer service and absolute equipment reliability remain the keys to success at G.C. Evans. “Think about it,” explained Dave McNamer. “If a beverage pasteurizer were to have a drive failure, you’re not only talking about lost product in the unit, but stopping a production line to the tune of potentially hundreds of thousands of dollars per hour. I don’t want to worry about our drives and I don’t want our customers to either. That’s why we choose NORD.”
