EnglishProfessional Botanical Extraction & Active Ingredient Engineering
BKYULA Biotech Co., Ltd. is a specialized manufacturer and worldwide exporter of standardized natural plant extracts, feed additives, functional mushroom powders, fruit & vegetable powders, and cosmetic bio-actives. Situated in Xi'an, Shaanxi Province—the premier hub of China's botanical extraction industry—we operate clean workshops aligned with international GMP food safety standards.
Our dedicated team of chemical engineers, phytochemists, and quality control analysts oversees end-to-end processing: from verified raw botanical origin screening to multi-stage extraction, low-temperature vacuum evaporation, precision pulverizing, and homogeneous blending. Every commercial batch is released only after stringent physical, chemical, and microbiological clearance.
SGS Verified Supplier
Our industrial production facilities, employee credentials, and storage capacities have been independently inspected and verified onsite by SGS Group.
Standardized Assays
Precise marker quantification via HPLC and UV spectrophotometry ensures reliable batch-to-batch active ingredient consistency for B2B formulators.
Comprehensive QA & QC
Equipped with analytical microbalances, biological safety cabinets, autoclaves, and microbiological incubators ensuring full compliance with USP/EP standards.
International Compliance
Certified across ISO 9001:2015, ISO 22000, HACCP, HALAL, KOSHER, and FAMI-QS for food, nutrition, pet feed, and cosmetic ingredient supply.
6-Stage Precision Production Flow
Every raw herb undergoes an integrated, document-controlled processing pipeline designed to preserve bioactive integrity and eliminate contaminants.
1. Botanical Extraction
Selected raw herbs are loaded into multi-functional stainless extraction units. Temperature, solvent ratios (deionized water or food-grade ethanol), and extraction cycles are logged digitally to maximize phytochemical yield.
- Continuous temperature and time tracking
- Multi-stage countercurrent extraction
2. Vacuum Concentration
Extracted liquid liquor is routed through spherical vacuum concentrating tanks. Low-temperature evaporation protects thermolabile active compounds from thermal degradation while recovering solvents efficiently.
- Reduced-pressure evaporation (under 55°C)
- Protection of bio-active molecular integrity
3. Drying & Dehydration
High-efficiency spray drying and vacuum belt drying convert refined concentrates into free-flowing powders. Parameters are optimized to yield instantaneous reconstitution, low bulk density variance, and minimal moisture.
- Loss on Drying controlled below 5.0%
- Spray drying and vacuum oven configurations
4. Smashing & Micronization
Dried botanical cakes and crystal granules are pulverized using mechanical impact mills. Vibrating sifters ensure uniform particle size distributions, commonly tailored to 80-mesh, 100-mesh, or ultrafine specifications.
- Tailored mesh range (80 to 200 mesh)
- In-line magnetic ferrous metal traps
5. Homogeneous Mixing
Multi-dimensional ribbon and three-dimensional motion mixers blend active powders to ensure complete batch uniformity. Ideal for standardized ratio extracts, vitamin-fortified pre-mixes, and customized buyer formulas.
- High mixing uniformity index (>99.5%)
- Multi-ingredient premix capability
6. Finished Product Inspection
Finished goods are double-bagged inside pharmaceutical-grade food PE liners and sealed within tamper-proof fiber drums. Batch release requires passing full analytical assay, heavy metal, and microbiological tests.
- Batch Certificate of Analysis (COA) provided
- 1 kg, 5 kg, 25 kg export standard packaging
