For coring, cutting, washing, drying and packing up to 2,500 kg per hour

The automatic processing and packaging line integrates a range of KRONEN machines with a solution from the KRONEN partner GKS Packaging. The line is used for complete processing from the raw material to the bagged end product. 

The raw products are processed whole. The system can be used for processing salad leaves, e.g. iceberg lettuce, frisée, endive and radicchio, or vegetables such as red and white cabbage (generally round cabbage varieties) and peppers. The respective capacity depends on the product and the packaging size. 

The following machines or solutions are integrated:

  1. Preparation: Multicorer (4B/2B) for coring, with waste belts and optionally with a quick lock for the cutting cassette
  2. Conveying: PLUS inclined conveyor belt with cleats
  3. Preparation: Trimming table for 6 people
  4. Cutting: GS 20 belt cutting machine , optionally with a large choice of different knifes
  5. Conveying: PLUS inclined conveyor belt
  6. Pre-washing: GEWA 5000 PLUS HELICAL washing machine with dipping belt outfeed 
  7. Washing: GEWA 5000 PLUS HELICAL washing machine with vibration outfeed, optionally including a  measuring and dosing system, insect removal drum and fine particle removal
  8. Drying: K850 drying system
  9. Further transport: PLUS inclined conveyor belt
  10. Weighing and packaging: Two GKS packaging solutions each with
    • Slope conveyor
    • Platform with multiple-head scales
    • FLEX L packaging machine, the bags can be optionally treated and also printed via a connection for gas flushing (MAP)
    • Outfeed belt, optionally with a metal detector
    • Rotary table for buffering

If a second product is fed into the GEWA washing machine via a second cutting machine or a second belt, for example different salads, the products are mixed simultaneously by the HELICAL washing system during the washing process.

The line is ideal for packaging bags up to 350 mm wide. For packaging in bags up to 500 mm wide, a FLEX XL can alternatively be offered instead of the FLEX L.

Benefits

KRONEN supplies automatic and semi-automatic processing lines – for different capacities and a continual, effective processing process

Continuous and gentle processing of high capacities

The production line handles lettuce and leafy vegetables in a continuous process and therefore requires only a small number of personnel. The communication between the SMART-version machines and the visual displays for the machine operators facilitates a reliable, constant and uninterrupted production flow. This in turn ensures high processing capacities and maximum efficiency and quality in production.
