From a Border Town to Global Markets: A Smart Macadamia Processing Upgrade in Nansan Town

GONGMAO Machinery and GONGMAO Works, founded in 1994, with 32+ experience, specializes in advanced nuts and food processing machinery, particularly complete processing solutions for customers worldwide.

We once worked with a macadamia processor in Nansan Town, Yunnan.Years ago, they had great raw nuts but suffered from outdated processing:

15% processing loss, low whole-kernel rates, and difficulty accepting high-end orders.Labor costs were high, efficiency was low, and they could only sell raw nuts at low prices.

Located on the China-Myanmar border, Nansan has excellent macadamia resources.With our full intelligent processing line — covering primary & refined processing — everything changed.

In the upgraded workshop:

• Intelligent grading system reaches over 98% sorting accuracy, cutting loss to 3%–5%.

• Precision drying stabilizes moisture at 10%±1%, keeping nuts fresh and safe.

• Intelligent shelling reduces breakage from 15% to only 2%–3%.

• AI optical sorting hits 99.5% accuracy, raising qualification rate to over 98%.

• Advanced packaging extends shelf life to 12–18 months, perfect for global export.

Results for this Nansan factory:

• Overall loss reduced to 8%
• Per capita output tripled
• Products entered high-end supermarkets in Europe, America & Southeast Asia
• Product premium increased by 40%

Today, the plant meets strict global standards:whole kernel rate ≥92%, peroxide value ≤0.15g/100g.

We do more than supply machines.We provide one-stop solutions: plant planning, customized equipment, process debugging and after-sales training.
