Assessing Your Current Hazelnut Processing Line

Identifying Manual Processes

Processors often begin by mapping each step in their hazelnut sorting workflow. They observe where operators manually inspect, classify, or handle nuts. Labor-intensive tasks, such as visual grading and removal of defective kernels, typically require significant time and attention. These manual steps can introduce inconsistencies and slow down throughput. Studies show that human classification remains time-consuming and prone to error, especially when sorting for quality or size. Deep learning models, including InceptionV3 and EfficientNet, now offer reliable alternatives by automating the detection of unwanted objects and damaged kernels. This shift reduces reliance on manual labor and enhances overall productivity.
