System Engineering Description & Technical Scope

Plant Architecture
Ready-to-eat salad solutions

Hadof Machinery delivers end-to-end turnkey processing solutions for fresh-cut, ready-to-eat salads and mixed greens. The line focuses on gentle product handling to prevent cellular bruising and extend supermarket shelf life. With multi-stage vortex current washing, chilled water sanitization, and variable-speed centrifugal dewatering, products maintain optimal crispness and nutritional integrity.

Key System Features

  • Gentle Vortex Action: Spiral water flow washes delicate leaves without mechanical damage.
  • Chilled Water Circulation: Integrated heat exchanger maintains wash water at 4°C to inhibit microbial growth.
  • Precision Slicing: High-speed servo cutters deliver clean, unbruised cuts for longer shelf-life.
