What makes the MEYER KI Series different from a standard color sorter?
+
The KI Series uses InGaAs composite infrared technology that detects materials based on their chemical composition, not just surface color. This means it can separate nut shells from kernels even when they are the same color — a task that is impossible for conventional color sorters. This makes it the only truly reliable solution for shell and kernel separation in nut processing.
Which nuts is the MEYER KI Series designed to sort?
+
The KI Series is specifically engineered for walnuts, almonds, pistachios, and macadamia nuts. Its belt-type gentle handling and anti-shattering system make it ideal for fragile premium nut kernels that require careful processing to maintain their shape, value, and grade.
What is InGaAs composite infrared technology and how does it work?
+
InGaAs (Indium Gallium Arsenide) is an advanced infrared sensor technology that detects differences in the near-infrared spectrum — beyond what the human eye or standard cameras can see. By analyzing the molecular composition of each particle passing through the sorter, it can distinguish between shell and kernel material even when their color, shape, and size appear identical.
What foreign materials can the KI Series remove from nut streams?
+
Beyond shell and kernel separation, the KI Series is highly effective at removing malignant impurities commonly found in nut processing streams, including glass fragments, sticks (rods), stones, plastic pieces, and other foreign objects — delivering clean, safe, export-quality output.
What models are available and what are their specifications?
+
The KI Series comes in three models: 60KI4 (4.2 kW, 680 kg, air consumption 1.5 m³/min, dimensions 3620×1345×2280 mm), 120KI4 (6.6 kW, 900 kg, 2.0 m³/min, dimensions 3620×1645×2280 mm), and 240KI4 (contact MEYER for full specs). All operate at 180–240V / 50Hz and 0.6–0.8 MPa air pressure.
How does the KI Series protect fragile nut kernels from breakage?
+
The KI Series uses a belt-type transfer structure that provides a smooth, stable drop path far gentler than chute-type mechanisms. Combined with the intelligent anti-shattering technology and soft landing design, the machine significantly reduces kernel breakage and shredding during both sorting and ejection, protecting the value of premium whole or half kernel products.
Can the KI Series be configured for different sorting tasks?
+
Yes. The KI Series offers a focused range of configuration options allowing it to be tailored for either shell and kernel separation or for the targeted removal of foreign materials. This flexibility means nut processors can use the same machine platform for different quality requirements and production goals.
What after-sales support does MEYER provide for the KI Series?
+
MEYER provides comprehensive pre-sale and after-sale support including machine selection consultation, production line integration assistance, material testing at the MEYER Test Center, remote troubleshooting and diagnostics via PC or mobile, on-site commissioning and inspection, warranty service with free maintenance, spare parts supply, operator training, and long-term service level agreements.
