Inspect both sides of the product with dual-belt and in-flight vision systems

The Duett optical sorter from Protec is designed for sorting fresh vegetables, leafy products, and diced or sliced fruit, using a two-stage conveyor system combined with advanced optical inspection.

Product first passes over a horizontal belt, followed by an inclined belt, where it is lifted and separated. As the product leaves the second belt, it is inspected in-flight, allowing the vision system to analyze both sides of each item.

High-resolution cameras, supported by powerful lighting systems (including optional backlighting and infrared/NIR), detect defects such as:

• Rot spots and discoloration
• Foreign bodies and insects
• Peels, pits, and stones
• Surface damage or burn marks

Once defects are identified, they are removed using a compressed air jet rejection system, ensuring continuous product flow.

The system is highly flexible and can be configured for a wide range of products, including olives, apples, pears, potatoes, carrots, leafy greens, beans, and peas, both fresh and processed.

Available in configurations with belt widths of ~1,050 mm and ~1,500 mm, the machine handles capacities from approximately 3 to 15 tons per hour, depending on product type and sorting requirements.

A touchscreen HMI with integrated control software allows quick adjustment of sorting parameters, making it easy to switch between products. The system also supports remote diagnostics and LAN connectivity, enabling integration into larger processing lines.

Detect and remove aflatoxin-contaminated kernels with optical and air jet sorting

The Toxtri optical sorter from Protec is specifically designed for detecting and removing aflatoxin-contaminated corn kernels. The system uses a combination of specialized lighting and high-resolution cameras to identify contaminated product based on fluorescence.

Under controlled illumination, kernels affected by aflatoxins exhibit a distinct fluorescent response, allowing the vision system to differentiate them from healthy kernels in real time. Once detected, contaminated kernels are removed using a precision air jet rejection system, ensuring continuous product flow without manual intervention.

This targeted sorting process enables producers to significantly reduce contamination levels, supporting compliance with food and feed safety standards while minimizing product loss.

The system is particularly relevant in regions or applications where mycotoxin risk is elevated, providing an automated and reliable method for improving product safety in corn processing lines.

Detect and remove defects from grapes before crushing

The X-Tri optical sorter from Protec is designed for sorting grapes after destemming, ensuring that only high-quality fruit enters the crushing and fermentation stages.

After destemming, grapes are distributed onto a vibrating feeder, which ensures even product spread onto the inspection belt. A high-speed optical vision system analyzes each grape in real time, detecting defects such as leaves, stems, insects, foreign materials, and unripe grapes based on color differences.

Once identified, unwanted material is removed using targeted air jets, allowing defective elements to be separated without interrupting the product flow. Accepted grapes continue directly to the crusher, maintaining a continuous processing line.

Sorting parameters can be adjusted via a touchscreen interface, enabling operators to define which defects should be removed depending on grape variety, ripeness, and desired wine profile.

The system is available in multiple configurations with capacities up to approximately 15 tons per hour, depending on grape characteristics and defect load.

Inspect and remove defects using vision systems and vacuum suction

The AspirX optical sorter from Protec is designed for sorting soft and wet products, including tomato pulp, fruit compotes, dices, and extruded products. It combines high-resolution vision technology with a vacuum-based rejection system, enabling accurate sorting while preserving product quality.

Product is conveyed on a belt and inspected by high-speed, high-resolution cameras, detecting defects such as off-color, rot, and discoloration, including in darker product streams. The system can identify defects down to approximately 0.5 × 0.5 mm, with real-time processing handled by dedicated electronic systems.

Unlike air-jet systems, rejected product is removed via suction through rows of hollow cylinders, ensuring full belt coverage and controlled removal. This method significantly reduces the amount of good product removed вмеÑте with defects, especially important for fragile or moist products.

Different configurations are available depending on product type:

• Small-diameter suction for pulp applications to minimize product loss
• Larger suction elements for diced products to ensure effective rejection

The system is available in multiple sizes with capacities ranging from approximately 5 to 20 tons per hour, depending on the model and application.

A touchscreen HMI with integrated monitoring software allows operators to track reject rates, air pressure, and system performance, with both automatic and manual control modes. The machine also features easy-clean design, including washable suction lines and waste tanks, supported by a liquid-ring vacuum pump for stable operation under high rejection loads.

Detect and remove defects using high-speed cameras and air jets

The DixAir optical sorter from Protec is designed for high-capacity sorting of vegetables, diced tomatoes, and fruit, using advanced vision systems combined with air jet rejection.

Product is transported on a conveyor belt, where it is inspected by high-resolution linear cameras supported by dedicated lighting systems, including backlighting for enhanced defect visibility. The system detects defects such as off-color, rot, and discoloration, with detection sensitivity down to approximately 0.5 × 0.25 mm.

Image data is processed in real time using high-speed processors (DSP, FPGA) and proprietary software. When a defect is identified, the system activates air nozzles (solenoid-controlled) to remove the defective product from the stream without interrupting flow.

The sorter is available in multiple sizes with capacities up to 90 tons per hour, depending on the model and product, and belt widths up to 1500 mm. Conveyor speed can be adjusted up to 4 m/s, allowing adaptation to different product types and throughput requirements.

The machine includes a touchscreen HMI with integrated monitoring software, enabling operators to adjust parameters, monitor performance, and control sorting accuracy. Connectivity via Ethernet (TCP/IP) allows integration into plant control systems, with optional remote diagnostics and support.
