Why choose RDS Sorting Line with dry unloading

  • Compact dimensions and versatility:
    Thanks to its design, the RDS sorting line takes up less space than bowl-type lines with the same number of outlets, allowing for better utilization of space in the production hall. A throughput of 3 tons per hour per lane makes the RDS line an ideal solution for intensive harvesting seasons.
  • Precise fruit sorting:
    The RDS line is designed for sorting fruits such as apples, peaches, apricots, and citrus fruits. Thanks to advanced roller technology, the machine ensures accuracy and gentle processing of products ranging in diameter from 40 mm to 100 mm.
  • Efficiency and flexibility:
    The innovative sorting system allows for the simultaneous measurement of various fruit parameters, such as weight, size, and color, without the need to transfer data between machine segments. This solution not only increases efficiency but also minimizes the risk of mechanical damage, which is crucial for delicate fruit.
  • Prospects for further development:
    The RDS machine offers extensive development options, allowing us to fully adapt the production line to customer needs and growing market demands. Depending on individual needs and process specifics, the line can be expanded with advanced modules and additional functions that significantly increase its efficiency and automation.
  • Expansion options include:
    • Palletizing: Adding a dedicated automatic palletizing line enables quick and efficient stacking of products on pallets, which significantly improves the logistics and transport process.
    • Individual Packaging: Possibility of implementing systems for packaging products in individual packages, ideal for industries requiring precise packaging. This makes the packaging process more efficient and precise, reducing operating costs.

Each of these options allows for the flexibility of adapting the line's functionality to current and future production challenges. Our solutions are scalable and modular, meaning they can be expanded in stages to meet the needs of a growing company.
