Overview
The EX-TE Series Experimental Multifunctional Herbal Extraction Tank is a bench-to-pilot scale integrated extraction system engineered for precise, reproducible, and scalable phytochemical isolation under controlled thermal, mechanical, and acoustic conditions. Based on jacketed pressure-vessel architecture with internal heating elements and programmable agitation, the system supports multiple extraction modalities—including decoction, maceration, reflux, forced-circulation percolation, volatile oil distillation, and solvent recovery—within a single modular platform. Its design adheres to fundamental principles of mass transfer kinetics and thermodynamic equilibrium in solid–liquid extraction, enabling systematic optimization of yield, selectivity, and stability for thermolabile or structurally complex bioactive compounds (e.g., glycosides, alkaloids, polyphenols, terpenoids). The tank operates within Class I pressure vessel safety guidelines per GB/T 150 (China) and incorporates engineering safeguards aligned with ISO 13850 (emergency stop), IEC 61000-6-3 (EMC), and ASME BPE-2021 hygienic design concepts for laboratory-scale bioprocessing equipment.
Key Features
- Modular capacity range: Six standardized models (EX-TE-03 to EX-TE-100) with nominal working volumes from 3 L to 100 L—enabling direct scalability from screening to process development.
- Integrated dual-zone thermal control: Electric resistance heating elements embedded in both vessel wall and bottom ensure uniform thermal distribution; independent monitoring of jacket temperature and internal extract phase temperature.
- Triple-layer thermal insulation: Vacuum-insulated jacket + mineral wool + stainless-steel cladding minimizes heat loss and improves energy efficiency during prolonged extraction cycles.
- Open-top structural design facilitates rapid loading/unloading, visual process observation, and in-situ sampling without system depressurization.
- Programmable agitation system: Adjustable speed (0–120 rpm) and torque-controlled impeller types (anchor, paddle, or frame) accommodate diverse botanical matrices—from powdered herbs to whole roots or fruit pomace.
- Comprehensive safety interlocks: Low-level cutoff prevents dry-heating of heating elements; overpressure relief valves rated at 0.09 MPa (vessel) and 0.4 MPa (jacket); real-time fault logging via central controller.
- Expandable multi-unit configuration: Standardized mounting interfaces and synchronized PLC architecture allow up to 20 parallel EX-TE units to operate under unified HMI supervision for high-throughput comparative studies.
Sample Compatibility & Compliance
The EX-TE series accommodates heterogeneous solid-phase feedstocks including dried herbal powders, granules, pellets, fresh plant tissues, animal-derived biomaterials (e.g., collagen-rich tissues), and food-grade starches or proteins. It supports aqueous, hydroalcoholic, and low-boiling organic solvents (e.g., ethanol, acetone, ethyl acetate) with vapor recovery integration. All wetted parts are fabricated from ASTM A240 316L stainless steel (Ra ≤ 0.8 µm surface finish), compliant with USP , FDA 21 CFR Part 11 data integrity requirements when paired with optional audit-trail-enabled software, and suitable for GLP/GMP-aligned R&D environments. The system meets ISO/IEC 17025 calibration traceability standards for temperature, pressure, and time measurement subsystems when validated using NIST-traceable references.
Software & Data Management
Equipped with an industrial-grade touchscreen HMI running embedded Linux OS, the EX-TE controller records time-stamped operational parameters—including temperature profiles, agitation duty cycle, vacuum setpoints, pH trends, and ultrasonic duty ratio—at user-defined intervals (1 s to 10 min resolution). Data export formats include CSV, PDF reports, and OPC UA-compatible streams for integration into LIMS or MES platforms. Optional software modules provide automated method sequencing, deviation alerting (email/SMS), electronic signature support per 21 CFR Part 11 Annex 11, and trend analysis tools for DOE-based extraction optimization. All firmware updates are digitally signed and verified prior to installation.
Applications
This system serves as a primary tool in natural product research labs, pharmaceutical preformulation units, functional food development centers, and contract research organizations conducting extraction process validation. Typical use cases include: quantification of extraction kinetics for pharmacopeial monographs (e.g., Chinese Pharmacopoeia ChP 2020, USP ); optimization of ethanol concentration and temperature for flavonoid recovery from Ginkgo biloba; comparative assessment of ultrasound-assisted vs. conventional reflux for curcuminoid yield from turmeric rhizomes; pilot-scale solvent recycling studies for green chemistry compliance; and development of continuous-percolation protocols for high-viscosity mucilage-containing materials like Althaea officinalis. Its flexibility also extends to non-pharma applications such as pigment extraction from annatto seeds, caffeine isolation from green coffee beans, and enzymatic hydrolysate preparation from soy protein isolates.
FAQ
What pressure ratings apply to the EX-TE vessel and heating jacket?
The inner extraction chamber is designed for a maximum operating pressure of 0.09 MPa (gauge), while the steam/water jacket is rated for 0.3–0.4 MPa—ensuring safe operation under elevated temperature reflux and vacuum-assisted distillation.
Is the ultrasonic module compatible with all EX-TE models?
Yes—the transducer assembly, generator, and immersion probe are fully scalable across the entire model range and integrate seamlessly with the main controller for synchronized parameter logging.
Can the system be validated for GMP-regulated workflows?
With IQ/OQ documentation packages, calibrated sensor certificates, and optional 21 CFR Part 11-compliant software, the EX-TE series supports formal validation in regulated development laboratories.
What maintenance intervals are recommended for the agitation and heating systems?
Routine inspection every 500 operating hours; bearing lubrication every 2,000 hours; thermal element resistance verification annually or after 10,000 cycles.
Does the system support external communication protocols for lab automation?
Standard Ethernet/IP and Modbus TCP interfaces are provided; optional PROFINET or CANopen modules are available upon request for integration into automated lab infrastructure.
