How can harvested hazelnuts in shell be efficiently transformed into high-value, market-ready hazelnut kernels while minimizing breakage rates? This is precisely the process innovation achieved by our Turkish client—a leading hazelnut exporter—through the introduction of our complete hazelnut shelling line.
Client background and core requirements
Our client is based in Turkey, the world’s largest producer and exporter of hazelnuts. The company specializes in supplying high-quality hazelnut kernels to European and Middle Eastern markets, where its products are widely used in the chocolate, pastry, and snack industries. In the international market, kernel integrity is a key factor determining grade and price.
The client’s existing production line features outdated equipment that not only operates at low efficiency but also suffers from persistently high hazelnut kernel breakage during shelling. This results in significant quantities of kernels that could be sold as Grade 1 being downgraded, directly impacting corporate profits.
Consequently, they urgently require a new production line characterized by high automation, gentle shelling, and thorough separation.
Taizy tailor-made solution
We provided our client with a fully integrated production line featuring seamless workflow. The solution comprised: a bucket elevator for automated feeding, a hazelnut shelling machine, and a shell-kernel separator, all interconnected via conveyor belts for smooth operation.
Based on the customer’s desired daily processing capacity, we recommended adding a pre-shelling grading stage. This pre-sorts hazelnuts by size, allowing the shelling machine’s adjustable gap function to operate at peak efficiency and further enhancing overall processing results.
Core advantages of our hazelnut shelling line
Addressing our clients’ core requirements for “high integrity rate” and “high purity,” we highlighted the technical strengths of two key pieces of equipment in our hazelnut shelling line:
Adjustable gap: the core feature of this equipment lies in its precisely adjustable shelling roller gap. Operators can easily adjust the distance between the rollers based on the batch size of the hazelnut raw material. This ensures an exceptionally high shelling rate (typically >98%) while maintaining an extremely low kernel breakage rate (<5%).
Vibratory shell-kernel separator: this unit ingeniously combines two physical separation principles. The dual separation mechanism guarantees outstanding separation purity (>99%), significantly reducing the workload for subsequent manual sorting.
Taizy’s Services
We eliminate customer concerns through unparalleled transparency and reliability. Before shipping equipment, we:
Provide comprehensive test operation videos: we procure hazelnut raw materials and conduct full-process testing from feeding and shelling to kernel separation. High-definition videos documenting the entire process are sent to clients, enabling them to visually assess equipment efficiency, shelling effectiveness, and separation purity.
Demonstrate meticulous, secure packaging: we employ multi-layered protective packaging. Each machine is tightly wrapped in moisture-proof, dust-resistant stretch film before being placed in sturdy plywood crates. Photographic documentation is provided for client verification.
Support real-time video inspection: before packing, we proactively invite clients to join video calls, allowing them to conduct comprehensive, real-time inspections of every machine detail. This includes verifying motor brands, stainless steel specifications, and vibrating screen mesh counts.
Positive feedback from the client
Upon the equipment’s arrival in Istanbul, our technical engineers guided the client’s team through the installation and commissioning of the entire production line using detailed layout diagrams and remote video calls.
Today, the client’s factory produces higher-grade hazelnut kernels with enhanced efficiency, successfully securing orders from multiple European premium chocolate brands known for their exacting standards on raw material quality.
