The stevia extraction machine from Xi'an Bioland Instrument is the most advanced way to get high-quality steviol glycosides from Stevia rebaudiana leaves. With our system, extraction rounds are finished in just 24–40 minutes, which is 50–500% faster than with standard methods. This industrial equipment is designed to meet good manufacturing practices (GMPs) and is explosion-proof. It also has PLC control for smooth operation. The method keeps low-temperature processes at 40–60°C, which protects heat-sensitive glycosides and achieves recovery rates of over 95%. Our solution is perfect for companies that need pharmaceutical-grade purity for making drinks, supplements, and tabletop sweeteners. It can be built out of 316 stainless steel if they want to, and it can be modularly designed to support ultrasonic-assisted extraction (UAE), reflux, and organic solvent extraction (OSE).

Our stevia extraction machine employs multi-stage unit operations for superior glycoside purity.
Phase 1: Cell Disruption
Plant cell walls are broken down by ultrasonic extraction. This speeds up the release of steviol glycosides while reducing damage from heat.
Phase 2: Solvent Extraction
A controlled blend of water and ethanol flows through stevia leaves that have been made. The method keeps the temperature and pressure just right for the best breakdown.
Phase 3: Filtration & Clarification
With precision vacuum filtering, solid particles are taken out. After flocculation, proteins and colours that make the water bitter are removed.
Phase 4: Resin Adsorption
Target glycosides are caught by macroporous resin columns. With this chromatographic separation, the tannins and wax that aren't needed are taken away.
Phase 5: Concentration
Multi-effect falling film evaporators lower the amount of liquid when there is no air flow. Low boiling points protect the purity of compounds and make it easy to recover fluids.
Phase 6: The cleansing
Nanofiltration membranes are an optional way to get pharmaceutical-grade clarity by getting rid of heavy metals and biological matter that is still present.
Raw Stevia Leaves → Washing & Drying → Size Reduction → Extraction Tank (UAE + Solvent) → Solid-Liquid Separation → Clarification → Resin Column Adsorption → Elution → Concentration (Evaporation) → Membrane Filtration → Crystallization/Spray Drying → Final Stevia Powder
Integrated Closed-Loop System
Solvent vapors route to condensers for recovery. Recovered ethanol feeds back into extraction cycles. This reduces operational costs by 30% while meeting environmental regulations.
CIP (Clean-in-Place) Integration
Automated cleaning sequences sanitize tanks and pipelines between batches. This ensures zero cross-contamination for multi-product facilities.
Beverage Industry
Make Rebaudioside A (Reb-A 97–99%) that is very pure for fizzy drinks, energy drinks, and flavoured waters. The clean taste quality that global names want is what our equipment gives them.
Pharmaceutical Manufacturing
Make stevia that is of a pharmaceutical excipient grade for diabetic medicines and mouth care goods. Membrane filtering gets rid of pyrogens so that regulatory file requirements can be met.
Food Production
Offer liquid concentrates for desk sweeteners, baking mixes, and replacements to dairy. Modern heat exchangers can handle fluids with a high viscosity without causing crystallization.
Nutraceutical Supplements
Get uniform stevia compounds for use in health goods. Consistency from batch to batch makes sure that supplement formulas are reliable.
Cosmetic Formulations
Get natural sweeteners for skin care items, lip balms, and toothpaste that need ingredients that aren't high in calories.
Material Verification
All stainless steel components undergo X-ray Fluorescence (XRF) analysis. This confirms alloy composition and corrosion resistance.
Sanitary Compliance
Orbital welds receive endoscopic inspection. We guarantee zero dead legs where bacteria could accumulate, meeting AWS D18.1 standards.
Pressure Safety
Extraction vessels undergo hydrostatic testing at 1.5x operating pressure. This validates performance under both vacuum and positive pressure conditions.
Factory Acceptance Testing (FAT)
We simulate complete extraction cycles before shipment. PLC logic, temperature accuracy (±1°C), and flow control receive validation with documented results.
Performance Documentation
Test runs include HPLC analysis proving glycoside recovery rates and solvent residue levels below 50ppm industry thresholds.
Q: How does your machine prevent the bitter aftertaste in stevia extracts?
A: Our equipment uses selective resin adsorption and nanofiltration sequences. These steps strip proteins, pigments, and bitter compounds while retaining sweet glycosides.
Q: Can the system process different grades of stevia leaves?
A: Absolutely. The PLC control allows parameter adjustments for varying leaf qualities. Lower grades may require extended resin column residence times, which our software supports.
Q: What's the solvent recovery efficiency?
A: Our multi-effect evaporators with rectification towers achieve over 95% ethanol recovery. Vacuum operation lowers boiling points, cutting energy costs significantly.
Q: How long does the resin last in adsorption columns?
A: With automated acid/alkali regeneration cycles, macroporous resins typically last 2–3 years. Built-in back-flushing protocols extend operational life further.
Q: What facility requirements are needed for installation?
A: You'll need steam generation, chilled water, compressed air, and 3-phase power. For ethanol use, facilities must meet Class 1 Div 2 explosion-proof standards.
Q: Do you provide training for operators?
A: Yes. We include comprehensive technical training covering operation, maintenance, and troubleshooting as part of our turnkey service.
Q: What's the typical energy consumption?
A: Energy use varies by capacity, but our closed-loop solvent recovery and vacuum concentration reduce consumption by approximately 40% compared to traditional batch extractors.
