Ishida Weigher Boosts Yield for Packed Salad

Friday 22 June 2007

Increased yield - at a level previously considered unattainable for salad products - is one of the major benefits that Gartenfrisch Jung GmbH has experienced with a 14-head weigher from Ishida’s new, advanced R-Series.

The company produces 50,000 bags and 36,000 trays of salad daily for the retail market, as well as 25 tonnes for the catering industry. Based in Jagsthausen, Germany, it uses its own locally grown vegetables, when in season, and ingredients from Southern Europe and North Africa at other times.

Because of the importance of maximising yield, Gartenfrisch organised a trial of the new model against a 10-year old 14-head Ishida RZ machine which, in its day, was one of the fastest salad machines on the market. For each trial, the machines were run on the same day, under identical conditions and using the same salad mix. All packs were checkweighed after multihead weighing, to ascertain the actual weight. The average weight variation on the new machine was much smaller and had not been considered achievable with salad before. Giveaway per pack was also significantly reduced, by over 2.5% on average. Thus, for every 40 packs of salad produced, the new machine delivers one extra pack from the same amount of washed and prepared material. As Jürgen Schwarz, Production Manager at Jagsthausen, puts it: “For us, less giveaway means more profit.”
