Development History
2014: Established the factory — 2018: Commenced production — 2018-2021: Explored deep processing and branding without success — 2021-2023: Focused on initial walnut processing, primarily using Xinjiang walnuts; found that labor-intensive processing was unsuitable for large-scale development. 2023-present: Focused on mechanized development of local walnuts in Shanxi
June 2023: First local walnut production line put into operation
September 2023: Shipped to the first European customer
November 2024: First European customer provided quality feedback and re-ordered
January 2025: Products distributed to domestic factories (including Hong Kong) and multiple international markets, including France, the UK, Germany, Spain, Turkey, etc.
April 2025: BRC certification upgraded from Class B to Class A.
1、Walnut Kernel Production Processes and Quality Management
Raw Material Handling:
Control the quality of output (color and impurities) through scientific ratio of raw materials
Impurity Removal
Eliminate foreign objects and defective kernels from raw materials to ensure product quality
2、Foreign Object Management
One leakage check, one suction, one manual sorting, three filters, one comprehensive inspection
3、Shell Debris Management
One ratio adjustment, two sampling inspections, three stability controls
4、Defective Kernel Management
Raw Material Quality Control: Regularly sample raw materials and ingredients to ensure defective kernels account for <0.3%, with strict monitoring to guarantee product quality
Modeling and Process Optimization: Use the Meiya C modeling method, performing two rounds of elimination to reduce defective rates and improve efficiency
Inventory Management: 1. Increase ventilation in the early stage to reduce mold growth; 2. As processing scale expands, extend to green husk processing to reduce mixing of old fruits
5、Microbiological Management
Hand washing and disinfection + High-frequency workshop disinfection + Air disinfection + Production line disinfection + Experimental verification
6、Color Management
Control of Abnormal Colors in Baked Products and Standard Color Difference Analysis
7、Specification Management
Simple to manage; frequently replace screens to prevent blockages causing uneven specifications
Ensure screen mesh is unobstructed to maintain product uniformity
8、Freshness Management
(1)After purchasing raw walnuts, ventilate the warehouse for one month to prevent increased mold
(2)From May to June, processed walnut kernels are directly vacuum-sealed and stored in cold storage
(3)After processing, products are not stockpiled and are shipped promptly
Warehouse ventilation to prevent mold; raw walnuts are refrigerated after processing
9、Other Management
(1)Management of rejected materials: Rejected materials are not reprocessed into main products
(2)Product turnover management: Disinfection, covered containers, no contact with the ground to prevent foreign objects and microbial growth
(3)Management of dropped materials: Dropped materials are not reprocessed into main products
