Detailed Process Flow: Manufacturing Walnut Pieces 1kg
The production of high-grade walnut pieces, such as the Chinese Walnut Kernels Pieces Walnut Kernels LP, involves a sophisticated multi-stage process designed to ensure purity, optimal sizing, and preservation of nutritional value. Our commitment to excellence is reflected in every step, adhering to international testing standards like ISO 22000 and HACCP.
1. Sourcing and Initial Quality Inspection
Raw walnuts are sourced directly from reputable orchards, ensuring varietal integrity and optimal maturity. Upon arrival, a rigorous visual and physical inspection is conducted to assess quality parameters such as shell integrity, size uniformity, and absence of foreign materials. This initial stage is critical to guarantee the foundational quality of the eventual piece of walnut.
2. Cleaning and Shelling
The inshell walnuts undergo a meticulous cleaning process to remove dust, debris, and any remaining field contaminants. Subsequently, they are fed into advanced automated cracking machines. These machines are precisely calibrated to minimize kernel damage while efficiently separating the shells, ensuring a high yield of intact kernels, which are then processed into walnut pieces 1kg.
3. Kernel-Shell Separation
Following cracking, a sophisticated system of air classifiers, vibratory screens, and density separators is employed to achieve a precise separation of kernel fragments from shell particles. This stage is crucial for ensuring the purity of the walnut pieces 1kg product.
4. Sorting (Manual and Optical)
Kernels then pass through multi-stage sorting. High-precision optical sorters utilize advanced imaging technology to detect and remove discolored, damaged, or foreign materials. This is complemented by skilled manual sorting, where experienced personnel meticulously inspect and remove any remaining imperfections, guaranteeing an exceptionally clean product.
5. Sizing and Cutting to Pieces
Sorted kernels are then directed to sizing equipment that categorizes them into various grades (e.g., halves, quarters, large pieces). For walnut pieces 1kg, specific mechanical cutting processes are employed to achieve the desired granular consistency, ensuring uniformity in size and shape that meets industrial specifications for applications like baking or trail mixes.
6. Final Quality Control & Lab Analysis
Before packaging, samples are taken for comprehensive laboratory analysis. This includes:
- Moisture Content: Ensuring stability and preventing microbial growth (target typically <6%).
- Peroxide Value (PV): Indicating oxidative rancidity (target typically <3 meq/kg).
- Free Fatty Acids (FFA): Reflecting hydrolytic rancidity (target typically <1.5%).
- Microbiological Testing: Screening for pathogens (e.g., Salmonella, E. coli) and total plate count.
- Organoleptic Assessment: Expert sensory evaluation for flavor, aroma, and texture.
Our process adheres to international standards such as ISO 22000, HACCP, and GMP, guaranteeing food safety and consistent quality. This meticulous control ensures a high-quality piece of walnut for industrial partners.
7. Packaging and Storage
The finished walnut pieces 1kg are immediately packaged to preserve freshness and extend shelf life. This typically involves vacuum packaging or inert gas flushing (e.g., nitrogen) in multi-layer barrier bags to minimize oxygen exposure. Packaging into 1kg units caters to specific industrial batch requirements. Products are then stored in climate-controlled warehouses, maintaining optimal temperature and humidity to prevent oxidation and maintain sensory attributes.
