Innovative and networked \u2013 intelligent and efficient weighing, washing, drying and sorting<\/h4>\n\n\n\n

The fully automated, networked processing line integrates innovative washing and drying technology from KRONEN with a dynamic weighing system from iWEIGH and mechanical and optical sorting solutions from HiTec Food Systems. All components of the line are networked. This ensures constant, low-interruption processing and low personnel requirements. At the same time, a cost-efficient process, high capacities and maximum quality in production are guaranteed. The innovative system sets new standards in terms of hygiene.<\/p>\n\n\n\n

The following machines or solutions are integrated:<\/h4>\n\n\n\n
    \n
  1. Weighing in and conveying: <\/strong>Flow Weigh Belt System, a dynamic recipe weighing beltby iWEIGH<\/li>\n\n\n\n
  2. Sorting:  <\/strong>Mechanical sorting system by HiTec Food Systems and visual sorting system by Optimum<\/li>\n\n\n\n
  3. Conveying and weighing:<\/strong> PLUS inclined conveyor belt and a weighing belt by iWEIGH, which communicates with the recipe weighing belt for an optimized product flow<\/li>\n\n\n\n
  4. Pre-washing:<\/strong> GEWA AF \u201cActive Flume\u201d washing system with belt outfeed,<\/a> including a water chute for gentle product intake, insect and fine particle removal with an extended contact surface and an air section with an integrated sand trap.<\/li>\n\n\n\n
  5. Washing:<\/strong> GEWA XL HELICAL washing machine with belt outfeed, including a water chute for a gentle product intake, sand trap sedimentation unit and lateral fine particle removal drum<\/li>\n\n\n\n
  6. Drying:<\/strong> K850 drying system <\/a> including water drainage with a flexible drip guard on the belts as well as advance dewatering<\/li>\n\n\n\n
  7. Further transport and weighing:<\/strong> Standard trolley weighing system by iWEIGH for continuous filling of standard containers up to 300 l<\/li>\n<\/ol>\n<\/div>\n\n\n\n

    Application options and capacities:<\/h4>\n\n\n\n

    The system is optimized for processing light, delicate, leafy products such as baby leaf lettuce as well as mixed salads, which are weighed in fully automatically. Leafy vegetables such as spinach, chard, radicchio, Chinese cabbage or kale can also be processed.<\/p>\n\n\n\n

    The capacity depends on the product. The line processes, for example:<\/h4>\n\n\n\n
