Why choose Cherry sorting line

  • Tenderness and safety of fruit:
    The 2LK-8 sorting line has been designed with cherries in mind – one of the most demanding and delicate fruits. The water unloading system ensures that the fruit is transported gently and safely, effectively minimizing the risk of bruising, cracking or loss of shine. Thanks to this, they retain their freshness, elasticity and attractive commercial appearance.
  • Precision Vision Technology:
    The heart of the line is the 2LK-8 sorting machine, equipped with a modern high-resolution camera system. Each cherry is analyzed in trade, which allows for an accurate assessment of its size, color, and external quality. Such technology guarantees exceptional repeatability of results, and at the same time allows the creation of many quality classes, tailored to different sales markets – both domestic and export.
  • High efficiency and continuity of operation:
    The compact design of the 2LK-8 line is characterized by a capacity of up to 1 ton of fruit per hour. The two-track design and automatic synchronization of the conveyors ensure a smooth flow of cherries through all sorting steps – from unloading to packaging. This means that the line will work well both in smaller farms and in large processing plants, where reliability and speed of operation in the peak season are important. The size of the line is adjusted to the needs of the farm.
  • Ergonomics and ease of use:
    Every step of the line is designed with operators in mind. Inspection platforms, packing tables and an easy-to-read control panel ensure convenient and safe operation of the equipment. The operation is quiet (noise level approx. 68 dB), and access to all components makes it easy to clean and maintain the machine. The safety features used, such as guards, emergency buttons and locks, guarantee the complete safety of personnel.

Main Features and Functions

  • Gentle unloading and preparation of fruit
  • Precise electronic sorting
  • Ergonomic packaging and advanced controls
  • Durability, efficiency and flexibility
  • Safety

The 2LK-8 line starts the process with a water unloading system, which allows the fruit to be safely received without the risk of bruising, cracking or loss of shine.
Transport in water stabilizes the movement of cherries and protects their surface from micro-damage, and three-stage filtration guarantees cleanliness of the circulation and a high level of hygiene.
A special "Z" type carrier conveyor gently lifts the fruit from the water tub to a higher level of the line, maintaining its shape and structure.
The fruit is then sent to inspection stations, where operators can pre-select – removing fruit that is damaged, too small or with tails – for better further sorting results.

At the heart of the line is the 2LK-8 sorting machine, which uses an advanced vision system with high-resolution cameras.
Each fruit is individually analyzed for size, color and surface quality, and the software classifies it according to the set parameters.
Thanks to its double-track design, the line achieves a capacity of up to 1 ton of fruit per hour, exceeding industry standards while maintaining full process gentleness.

At the end of the process, the fruit goes to SPD-7 packing tables with seven workstations.
Integrated START/STOP and emergency stop buttons ensure safety, while the ergonomic design makes it easy to pack quickly in cartons or containers.
The entire line is controlled from a central PLC panel that allows speed control, parameter monitoring and real-time management of work cycles.
The system guarantees reliability, intuitive operation and safety of use.

The structure of the line is made of materials resistant to moisture, corrosion and intensive use, and the elements are protected against corrosion.
Thanks to the precise synchronization of the conveyors and the low installed power (12 kW), the system is characterized by high efficiency with minimal energy consumption.
The design provides easy service access, spray nozzles and a dirt drainage system, which allows for quick cleaning without disassembly.
The modular design allows for expansion and customization – with additional tables, checkweighers or water cooling – so that the line can grow as the farm or plant grows.

Emergency Stop System:
The machine is equipped with safety switches that stop operation in the event of danger or opening of protective guards.
Low Noise:
ensures comfortable work for the operator, even during prolonged use.
CE Compliance:
The device meets the requirements of the European directives on machinery and electromagnetic compatibility.
