For more than 50 years, Zweifel Pomy-Chips, AG, (Spreitenbach, Switzerland) has been one of the largest snack food manufacturers in Europe. The company produces  about 5,000 tons of potato chips annually, and another 1,200 tons of snacks are produced from grain and corn.

Known for innovative chip flavors and recipes such as Nature, Paprika, Provençale, Curry and Mexican, Zweifel strives for quality coating and consistent delivery of the seasoning blend to the potato chip manufacturing process.  The problem was that existing equipment wasn’t delivering consistent quantities and perfectly repeatable blends to the coating process. This not only affected flavor but also wasted expensive ingredients when greater-than-needed amounts were delivered. Zweifel needed a better way to meter the ingredients to the coating process.
