Stage 01
Raw Materials
Direct farm-sourced botanicals undergo physical sorting, botanical identity verification (TLC/microscopic), moisture testing, and pre-screening for contaminants.
Operational Capability
Standardized Botanical Production Backed by Science
Xi'an Vexli Bio-Tech Co., Ltd. integrates origin-direct botanical sourcing with modern industrial extraction technology and strict analytical validation. Situated in Shaanxi Province—a traditional hub for herbal resources and botanical processing—our facility features high-standard cleanrooms, sealed stainless-steel extraction systems, low-temperature vacuum concentrators, and closed powder-handling workshops.
From raw herb incoming inspection to multi-stage crystallization, purification, spray drying, and clean packaging, every unit operation is systematically controlled to ensure strict batch-to-batch uniformity, international regulatory compliance, and total traceability.
Standardized SOP
The 9-Stage Botanical Extraction Process
Every active ingredient and superfood powder produced by Xi'an Vexli Bio-Tech Co., Ltd. adheres to an audited, reproducible manufacturing protocol designed to protect functional bioactives and maintain purity.
Stage 02
Extracting
Dynamic multi-functional solid-liquid extraction with deionized water or food-grade ethanol under strictly calibrated temperature, pressure, and time curves.
Stage 03
Concentration
Falling-film and vacuum external circulation concentrators reduce moisture at low operating temperatures to preserve thermosensitive phytochemicals.
Stage 04
Purification
Macroporous adsorption resins and nanofiltration separation remove inactive impurities, isolating target markers such as polyphenols, polysaccharides, or alkaloids.
Stage 05
Drying & Spraying
High-speed centrifugal spray drying and vacuum drying towers instantly convert purified concentrates into uniform, instantly soluble micro-powders.
Stage 06
Pulverizing
Ultra-fine airflow micronizers and mechanical pin mills crush dried solids into controlled particle sizes required for capsules, tablets, or liquid formulations.
Stage 07
Sieving
Vibratory grading screens separate powders from 80 up to 450 mesh, integrated with high-sensitivity rare-earth magnetic traps and inline metal detectors.
Stage 08
Mixing
Three-dimensional cone blenders ensure thorough homogeneity for custom active blends, carrier balances, and batch-to-batch color stabilization.
Stage 09
Finished Product
Sealed inside pharmaceutical-grade aseptic cleanrooms into food-grade polyethylene bags within tamper-evident drums, accompanied by a batch-specific COA.
Hardware Infrastructure
Industrial Processing & Extraction Machinery
Built with 304/316L stainless steel, automated CIP (clean-in-place) loops, and digital telemetry to guarantee clean-label integrity.
E-E-A-T Quality Assurance
In-House Analytical Laboratory & Testing Apparatus
At Xi'an Vexli Bio-Tech Co., Ltd., full chemical assay and microbial safety validation occur on-site before third-party SGS or Eurofins audits, ensuring complete regulatory compliance in destination markets.
Assay & Active Markers
Quantitative chromatography (HPLC, GC) and spectrophotometry (UV-Vis) verify purity, active compound concentrations (e.g. NMN, NAD+, Mogroside V, Polysaccharides), and absence of synthetic adulteration.
Contaminant Screening
Rigid monitoring for residual solvents via Gas Chromatography, elemental heavy metals (Pb, As, Cd, Hg) via atomic absorption, and BS EN 15662 pesticide multi-residue compliance for EU & North American entry.
Microbiological Integrity
Class-100 clean benches and precision incubators rigorously test Total Plate Count (TPC), Yeast & Mold, and test pathogen-free status for E. coli and Salmonella on every manufactured lot.
Innovation & Customization
R&D Pilot Laboratory & Formulation Development
From small-scale pilot extractions to developing unique analytical HPLC marker methods, our in-house engineering and R&D team works closely with global brand owners and formulators.
