Big boost in bagging salad

Zoltan Payerli of Salinas, CA-based Fresh Express is looking forward to Pack Expo Las Vegas 2001, scheduled for Sept. 10-12 at the Sands Expo and Convention Center. His attendance there two years ago led to the installation of a 16-head combination scale from Yamato, which is represented by Hayssen, a Barry-Wehmiller Co. (Duncan, SC).

This year at the show, which is sponsored by the Packaging Machinery Manufacturers Institute (Arlington, VA), he plans to investigate automatic casing machinery to further enhance company productivity.

Flexibility, speed, and precision are essential to Payerli’s work. Cleaned, chopped lettuce is constantly dumped onto the Yamato Sigma Series 516 combination weigher. With the help of an advanced computer system, the scale runs through many calculations until it determines which buckets combined hold an amount of lettuce closest to the target weight. Those buckets are then signaled to discharge their lettuce into the formed bag below.

The salad greens are mixed with gas in precise proportions in each package. That makes accurate weighments all the more important, says Payerli, national packaging team head at Fresh Express. (PR)
