Water unloading with pusher and drip tray

Water unloading from pusher and drainer

Water unloading is a modern solution designed to gently and efficiently empty fruit from pallet boxes and smoothly transfer them to the next stages of the production line. The system was designed for fruit farms, processing plants, and companies that prioritize high product quality, reduced bruising, and improved work organization.

Thanks to a carefully designed transport, positioning, and water unloading system, the product is handled in a controlled and safe manner. Using water as a transport element allows for the gentle emptying of fruit from the pallet box and its smooth transfer to subsequent technological processes. This solution supports modern automation systems and is suitable for applications where both efficiency and protection of raw material quality are important.

This device not only streamlines daily work, but also allows you to build a more repeatable, ergonomic and predictable fruit handling process right from the start of the line.

Application and Target industries

Water unloading of box pallets is suitable for:

• Horticulture: when handling fruit that requires gentle treatment.
•Food processingas the first stage of feeding the product for further processing, sorting or packaging.
•Logistics centers and sorting plants: wherever the smooth organization of the flow of pallet boxes and the reduction of manual work are important.

The perfect solution for companies that want to implement modern automation systems, improve product safety and develop their own production technology.

Why choose Water unloading of box pallets

  • Gentle product handling:
    The greatest advantage of water unloading is the reduction of mechanical damage. Fruit is not suddenly dumped, but rather gently absorbed by the water and directed for further transport. This is especially important for products sensitive to bruising and pressure.
  • Better process organization:
    The system organizes work at the beginning of the production line. A full pallet box is fed, positioned, emptied, and discharged in a predictable manner, improving the smooth operation of the entire process.
  • Effectiveness in practice:
    The use of a feeder, positioning mechanism, and empty pallet collection mechanism reduces manual labor and speeds up raw material handling. This provides real support for companies developing automation systems and seeking to increase productivity without compromising product quality.
  • Product and operator safety:
    The controlled unloading process improves work safety and reduces the risk of errors resulting from manually emptying pallet boxes. Furthermore, the entire system can be integrated with subsequent line elements, creating a cohesive and safe work area.
  • Adaptation to modern production:
    Water unloading is a solution that responds well to the needs of modern plants, where production technology is based on repeatability, quality and minimizing raw material losses.

Main Features and Functions

  • Application and organization of the process
  • Feeding, positioning and water unloading
  • Receiving empty pallet boxes and work ergonomics
  • Durability, resistance and operational safety

Water unloading of pallet boxes is designed for fruit requiring gentle transport and safe entry into the processing line. It is suitable for applications where damage minimization, smooth operation, and good product flow organization are key. Using several cooperating devices in a single system allows for streamlined line entry, increased efficiency, and reduced risk of downtime.

A box pallet feeder with a pressure mechanism positions the full box pallet in the correct position before unloading, ensuring a stable and repeatable process. The immersion module then gently empties the box pallet, and the product is transferred to a tub where the water takes over the transport function and gently guides the fruit to the next section of the line. This solution reduces bruising, improves process quality, and supports modern production technology.

After unloading, a gravity roller conveyor collects empty box pallets and passes them on without the need for manual handling. This streamlines the logistics of empty packaging, improves workstation ergonomics, and facilitates the safe organization of the line's infeed area. Reducing manual handling of box pallets increases operator comfort and supports process automation.

The devices are designed for operation in industrial and humid environments. Their robust stainless steel construction ensures durability, stability, and readiness for intensive seasonal use. The entire system supports a safe, predictable, and modern fruit unloading process.
