In China's largest tiger nut growing region, annual production reaches 200,000 tons — a vast raw material base driving the rapid growth of the tiger nut deep-processing market. A well-established company with years of experience in tiger nut processing sought to standardize product quality, boost production efficiency, and upgrade food safety through an intelligent production line.

However, almost no manufacturer in the industry had deeply studied tiger nut butter processing technology, leaving the customer with a clear need but no established path to follow. Rather than applying an off-the-shelf solution to a project with virtually no precedent, GELGOOG started from scratch — developing dedicated processing techniques tailored to the raw material properties of tiger nuts, and refining them through repeated testing and validation to deliver a fully customized, workable line design. This reflects GELGOOG's consistent approach to service: understand the need first, then design the solution — rather than selling equipment and asking the customer to adapt to it.

A Fraction of a Degree, a World of Flavor: Why Temperature Is Everything for Tiger Nut Butter

The quality of tiger nut butter depends heavily on precise temperature control. If the roasting temperature is too low, aroma cannot fully develop; if too high, it easily produces a bitter, burnt taste that compromises flavor. During grinding, frictional heat can likewise damage the oil structure, reducing both texture and nutritional stability.

At the same time, the customer wanted to further improve production efficiency, reduce quality variation caused by manual operation, and establish a more rigorous food safety management system. Achieving a stable, faithful reproduction of tiger nuts' natural flavor at scale became the central challenge of the project.

Intelligent Temperature Control: Unlocking Aroma and Texture

Guided by the customer's needs, GELGOOG combined an understanding of raw material characteristics, process requirements, and capacity planning to design a complete line solution built around precision heat exchange and intelligent temperature control.

Intelligent Roasting: Even Heating to Lock in Natural Aroma

The project uses GELGOOG's in-house developed roasting-cooling integrated machine. Through an optimized heat exchange design, it achieves even heating and precise temperature control across the material, effectively preventing the bitter, burnt flavor caused by localized overheating. The equipment combines roasting and cooling into a single process, shortening the overall processing flow and lowering the discharge temperature — better preserving the tiger nut's natural aroma and nutritional content, while supporting multiple process recipes to meet different product needs.

Dual Ultra-Fine Grinding: Preserving a Rich, Full-Bodied Texture

The line uses a combined stone mill and ball mill process, with precise temperature control applied throughout grinding to effectively reduce frictional heat. This improves grinding efficiency while producing a finer, more uniform paste — preserving the tiger nut's natural oil structure to the greatest extent and delivering a richer, smoother final texture.

60-Day Rapid Delivery: The Certainty of Going from Plan to Production

For a customer, choosing an equipment supplier means buying more than just a production line — it means buying the certainty of on-time, on-quality delivery. From plan confirmation to installation and commissioning, the project reached production in just about 60 days — a result made possible by GELGOOG's standardized project management system and efficient engineering execution. Today, the production line runs stably, flavor consistency has improved significantly, batch-to-batch quality is more stable, production efficiency has increased, and the customer's food safety management system has been further strengthened — laying the groundwork for future expansion into additional deep-processed products.

Customer Praise

Speaking about the collaboration, the customer's project representative said: “From the field to the finished product, every step of processing tiger nuts reflects our dedication — and that's exactly why we hold product quality to such a high standard. On this project, what mattered most to us was product quality, production efficiency, and food safety, and we wanted a more stable, standardized production system that could guarantee consistency across every batch.

“The GELGOOG team worked closely with us through multiple rounds of discussion and adjustment, taking into account our raw material characteristics, production processes, and on-site conditions — from automated line integration down to equipment materials and cleaning and maintenance, both sides kept refining every detail. That level of attention to detail aligns closely with our own philosophy of ‘from the field to the table.’

“Looking ahead, we're looking forward to deepening our collaboration with GELGOOG and working together to further unlock the value of tiger nut processing.”

Customer-Centered, Certainty Delivered

From a single tiger nut to a jar of premium tiger nut butter, what determines product value isn't just the equipment — it's precise control over every process detail, and whether every stage, from solution design and equipment manufacturing to installation, commissioning, and technical service, can be reliably delivered.

GELGOOG remains committed to a customer-driven approach, deeply integrating advanced equipment with proven process expertise to offer food processing companies worldwide a one-stop solution spanning solution design, equipment manufacturing, installation and commissioning, and technical service. What we deliver isn't just a production line — it's the certainty our customers can count on, helping them achieve higher quality, greater efficiency, and more sustainable growth.
