Modern Production Facility
Our facility in Xi'an features dedicated workshops for extraction, concentration, refining, and clean packaging designed for scalable bulk ingredient manufacturing.
Manufacturing Facility & Quality Control
Operational Capability
Industrial Infrastructure Built for Global Standards
Xi'an Vexli Bio-Tech Co., Ltd. operates standardized extraction lines, cleanrooms, and testing facilities engineered to comply with ISO 22000, HACCP, USDA Organic, EU Organic, Halal, and Kosher regulatory benchmarks.
Standardized Extraction Floor
Equipped with high-capacity stainless steel extraction reactors, multi-stage filtration units, and low-temperature vacuum concentrators to safeguard bio-actives.
Controlled Warehousing
Temperature- and humidity-monitored storage preserving the potency of sensitive powders, extracts, natural pigments, and clean-label sweeteners.
Standard Operating Procedures
Complete 9-Step Production & Refining Process
Every lot manufactured by Xi'an Vexli Bio-Tech Co., Ltd. follows a strictly controlled workflow to ensure batch-to-batch consistency and international compliance.
1. Raw Materials Inspection
Herbarium species validation, pesticide residue pre-screening, moisture check, and heavy metal baseline assays.
2. Controlled Extraction
Optimized solid-to-liquid ratio extraction using purified deionized water or food-grade ethanol at monitored temperatures.
3. Vacuum Concentration
Gentle low-temperature falling-film concentration preventing thermal degradation of delicate flavonoids and phytochemicals.
4. Column Purification
Macroporous resin separation and ceramic membrane filtration targeting specific active assays while removing ballast.
5. Drying & Spraying
Instant atomized spray drying producing free-flowing, instantly soluble micro-granules with strictly regulated residual moisture.
6. Precision Pulverizing
Ultrafine micro-milling calibrated to client-specified bulk densities and particle dimensions suited for tablets or drink blends.
7. Sieving & Metal Detection
Screening through 80 to 450 mesh specifications coupled with rare-earth magnetic separation and dual-aperture metal detectors.
8. Homogeneous Mixing
High-efficiency ribbon blending guaranteeing uniform active dispersion across commercial batch sizes up to multiple tons.
9. Cleanroom Packing
Double-layer food-grade polyethylene lined drums, nitrogen flushed bags, or custom private-label containers with full lot traceability.
