Yunnan Shanshui Walnut Industry Development Co., Ltd. was established in 2018 with a registered capital of 12 million yuan. Based in Fengqing County, Lincang City, Yunnan Province, the company specialises in the cultivation, production and sale of walnut and macadamia nut products.
The company currently operates three processing sites with an annual capacity of 800 tonnes for macadamia and walnut rough processing, alongside two additional sites processing 400 tonnes annually. It owns over 20,000 mu (approximately 3,300 acres) of walnut plantations and more than 8,000 mu (approximately 1,300 acres) of macadamia plantations.
The industrial park features two standardised factory buildings with an annual production capacity of 5,000 tonnes for walnut products and 3,000 tonnes for macadamia products. The company currently employs 31 permanent staff and over 100 seasonal workers. The company obtained its Food Production Licence, Export Food Production Enterprise Filing, and Import/Export Consignee Filing in 2022.
It completed ISO 22000 Quality Management System certification in 2023 and secured organic walnut and organic walnut kernel processing certification in 2024. The company comprises the following subsidiaries: Yunnan Lirennmei International Trading Co., Ltd., specialising in import and export operations; Fengqing County Hongcheng Modern Agricultural Development Co., Ltd., dedicated to walnut and macadamia cultivation and development; Fengqing Longwang Food Co., Ltd., responsible for primary processing of walnuts and macadamias; Fengqing County Shanshui Tiantian Technology Co., Ltd., managing e-commerce and online business operations.
Since commencing export operations in 2022, the company has generated over US$3 million in foreign exchange earnings, with annual sales exceeding RMB 30 million in 2023. The ‘Lirunmei’ brand products launched by the company have gained strong recognition from domestic and international distributors.
From source to finished product: Establishing a robust and reliable quality system for the entire nut industry chain
Deeply integrated intelligent and flexible production:
Equipment universally features parameter memory, automatic adjustment and remote monitoring capabilities, enabling swift switching between processing operations for different product specifications (such as macadamia nuts of varying sizes or different varieties of walnut kernels), flexibly responding to diverse market demands.
Technological Innovation in Traditional Craftsmanship:
We have replaced harsh alkaline soaking with purely physical opening, laborious manual sorting with intelligent colour sorting, and experience-dependent manual stirring with automated CNC stirring. This has completely eliminated unsafe traditional processing methods, making the production process safer, more environmentally friendly, and more sustainable.
From source to finished product: Establishing a robust and reliable quality system for the entire nut industry chain
In the nut industry, exceptional product quality stems not merely from meticulous processing, but originates in premium raw materials, is cultivated through professional management, and is ultimately validated by rigorous scientific testing.
Our company is deeply rooted at the industry's source, having established a comprehensive industrial ecosystem encompassing large-scale cultivation, specialised operations, and scientific quality control.
This not only underpins our production capacity and consistency, but also represents our solemn commitment to accountability at every stage of the product journey – from soil to table.
1. Scale and Regional Advantages:
We possess over 100 million mu of proprietary and cooperative plantations across core nut-growing regions globally. These bases are deeply rooted within prime cultivation zones, where exceptional climatic and soil conditions provide an ideal environment for species such as macadamia nuts and walnuts.
2. Scientific Cultivation Management:
We implement a standardised cultivation model based on ‘uniform varieties, uniform agricultural inputs, uniform management, and uniform harvesting’. Guided by our agricultural technical team, every stage—from soil improvement and water-fertiliser irrigation to green pest control and precision harvesting—is rigorously managed. This ensures the superior quality, consistent flavour, and food safety of our nut raw materials from the source.
3. Sustainable Industry Practices:
We regard our plantations as the foundation for long-term development, actively promoting ecological circular cultivation. We are committed to soil and water conservation alongside biodiversity protection, achieving harmonious coexistence between industrial growth and the natural environment. This ensures the long-term stability and sustainability of our raw material supply.
1. Agricultural Technology Expert Team:
Led by seasoned specialists in horticulture, plant protection and related fields, this team maintains year-round engagement at the cultivation frontline. Responsible for variety selection, cultivation technique R&D and dissemination, they form the foremost intellectual defence line safeguarding raw material quality.
2. Production Management and Engineering Team:
Production managers with decades of nut processing experience collaborate closely with engineers specialising in mechanical automation and process optimisation. This ensures every stage—from warehousing and pre-treatment to deep processing—operates with precision and efficiency.
3. R&D and Quality Control Team:
Food science researchers continually explore novel products and processes, while an independent quality control unit rigorously enforces monitoring standards throughout the entire journey from raw material inspection to finished product dispatch, serving as steadfast guardians of product quality.
4. Seamless Collaboration from Field to Factory:
This seasoned team, spanning breeding, cultivation, processing, quality control, and R&D, leverages deep industry expertise and efficient coordination to ensure unimpeded information flow, swift decision-making, and robust execution across the entire supply chain.
To guarantee every batch meets the highest safety and quality standards, the company has invested heavily in establishing a modern testing centre compliant with national certification standards. Equipped with internationally advanced detection instruments, this integrated facility forms a reliable quality assurance system.
