2. Green Spring Technology Revolutionizes Spirulina Harvesting and Drying Processes, Setting Industry Standards with Premium Products

Harvesting and drying are critical stages determining product quality in spirulina production. Through technological innovation and process optimization, Green Spring Technology has achieved breakthrough progress in these two areas, delivering higher-quality spirulina products to the market.

2.1 Precision Harvesting Maximizes Retention of Active Components

Green Spring Technology employs an advanced optical monitoring system that detects the absorbance of the culture medium in real time (560nm > 1.0 or 680nm > 0.8). This enables precise determination of the optimal harvest timing, ensuring spirulina is harvested when its nutritional content is at its peak. The company innovatively employs a multi-stage filtration system combined with proprietary bioflocculation technology. This approach enhances harvesting efficiency while effectively avoiding salt residue issues associated with traditional flocculants, ensuring product purity.

2.2 Intelligent Drying, Perfectly Preserving Nutrients

Addressing the short shelf life of fresh algae (only 6 hours), Green Spring Technology established an intelligent drying workshop:

· Multi-mode Drying System: Combines processes like spray drying and vacuum drying based on product requirements, maximizing nutrient retention while controlling costs;

· Low-Temperature Drying Technology: Proprietary low-temperature drying process effectively protects heat-sensitive nutrients, preventing active ingredient loss caused by traditional high-temperature drying;

· Energy-efficient design: Utilizes novel forming technology and specialized support systems, boosting drying efficiency by over 30% while significantly reducing energy consumption.

2.3 Quality Assurance, Setting New Industry Standards

Green Spring Technology implements stringent quality control during harvesting and drying:

· Fully enclosed production environment eliminates secondary contamination;

· Each batch undergoes nutritional component testing to ensure active ingredient retention rates;

· Comprehensive traceability system enables end-to-end monitoring from harvest to drying.

3 Spirulina Product Safety Under Scrutiny: Green Spring Technology Ensures Quality Through High Standards

As spirulina gains global market adoption, its safety increasingly draws attention from consumers and regulators. Spirulina exhibits strong adsorption capacity for pollutants in cultivation environments, including heavy metals, pesticide residues, and polycyclic aromatic hydrocarbons (PAHs).

3.1 Key Safety Risks and Current Control Measures

· Heavy metal contamination: Regional heavy metal residues exist in China's spirulina products, with southern products prone to lead exceedances and northern products exhibiting elevated arsenic levels. Green Spring Technology ensures compliance with domestic and international limits (lead ≤ 2.0 mg/kg, total arsenic ≤ 0.5 mg/kg) through rigorous selection of cultivation water sources and raw materials.

· Polycyclic Aromatic Hydrocarbons (PAHs) Control: Drying processes may introduce PAH contamination. Green Spring employs indirect heating and advanced drying technologies to eliminate heat-source contamination, ensuring products meet stringent EU standards (benzo[a]pyrene ≤ 10 μg/kg).

· Comprehensive Risk Management: The company implements an end-to-end quality control system from cultivation to processing, rigorously monitoring risk indicators such as nitrates, sulfites, and algal toxins to ensure product safety and reliability.

3.2 Green Spring Technology's High-Standard Practices

Green Spring Technology utilizes a closed photobioreactor system to eliminate environmental contamination risks at the source. The company's products hold international certifications including ISO, BRC, and IFS, strictly adhering to Chinese, EU, and US standards to provide consumers with safe, pure spirulina products.

Currently, Green Spring Technology has established a comprehensive quality traceability system.
