Anyan AYAN-3000YL Benchtop High-Temperature Spray Dryer

Overview

The Anyan AYAN-3000YL is a benchtop high-temperature spray dryer engineered for precise, repeatable powder synthesis from liquid or slurry feedstocks in research and development laboratories. It operates on the principle of rapid evaporative drying via pneumatic two-fluid atomization: feed solution is introduced into a co-current hot-air stream (inlet temperature up to 250 °C), where atomized droplets undergo near-instantaneous solvent removal—typically achieving 95–98% moisture reduction within 10–15 seconds. This co-current configuration ensures that droplets encounter peak thermal energy only briefly during initial contact; as evaporation proceeds, the local gas temperature drops rapidly, minimizing thermal degradation. The result is thermally sensitive materials—including proteins, enzymes, probiotics, and labile phytochemicals—can be converted into free-flowing, spherical, low-moisture powders with preserved bioactivity and structural integrity.

Key Features

• Co-current airflow design optimized for heat-sensitive samples, limiting particle surface temperature well below inlet air temperature
• Integrated oil-free air compressor enabling consistent, contamination-free atomization without lubricant carryover
• PID-controlled inlet temperature regulation with ±1 °C stability across full operating range (ambient to 250 °C)
• Automated needle-type nozzle cleaning system with adjustable frequency to prevent clogging during viscous or particulate-laden feed processing
• 7-inch color touchscreen interface supporting dual-language (English/Chinese) operation, real-time parameter monitoring, and manual/automatic mode switching
• All wetted surfaces fabricated from electropolished 304 stainless steel—compliant with ISO 8573-1 Class 3 for compressed air purity and suitable for GLP-aligned workflows
• Noise emission <60 dB(A), meeting ISO 7779 and EU Directive 2000/14/EC laboratory acoustic requirements
• Modular construction with tool-free disassembly of drying chamber, cyclone separator, and collection vessel for rapid cleaning and validation

Sample Compatibility & Compliance

The AYAN-3000YL accommodates aqueous and organic solvent-based solutions, suspensions, and emulsions with total solids content ranging from 5% to 90% w/w. It is routinely employed for drying heat-labile biologics (e.g., monoclonal antibody formulations, vaccine adjuvants), food-grade colloids (e.g., whey protein isolate, soy lecithin), ceramic precursors (e.g., alumina sols, zirconia nanoparticles), and pharmaceutical intermediates (e.g., amorphous solid dispersions). Equipment design adheres to mechanical safety standards per EN 61000-6-2 (EMC immunity) and EN 61000-6-4 (EMC emissions). While not certified for GMP manufacturing, its traceable temperature logging, locked parameter sets, and audit-ready operational logs support FDA 21 CFR Part 11–aligned data integrity practices when paired with validated SOPs.

Software & Data Management

The embedded control system records time-stamped inlet/outlet temperatures, feed rate, airflow, and chamber pressure at 1-second intervals. Data export is supported via USB to CSV format for post-processing in MATLAB, Python (Pandas), or statistical packages such as JMP. Optional Ethernet connectivity enables remote monitoring through secure HTTP(S) endpoints—compatible with institutional LIMS integration via RESTful API adapters. All parameter changes are logged with user ID, timestamp, and pre/post values, fulfilling ALCOA+ principles (Attributable, Legible, Contemporaneous, Original, Accurate, Complete, Consistent, Enduring, Available) for regulated R&D environments.

Applications

• Pharmaceutical R&D: Production of inhalable dry powders, amorphous solid dispersions, and excipient-free API microparticles
• Food Science: Encapsulation of omega-3 oils, probiotics, and anthocyanins; production of instant beverage bases and dairy analogs
• Materials Engineering: Synthesis of battery cathode precursors (e.g., NMC, LFP), catalyst supports, and nanostructured metal oxides
• Nutraceuticals: Stabilization of polyphenols, enzymes, and volatile terpenes without organic solvent residues
• Academic Research: Fundamental studies in droplet thermophysics, glass transition behavior of amorphous powders, and particle morphology–process parameter correlations

FAQ

What feed viscosities can the AYAN-3000YL handle?
Viscosity limits depend on nozzle orifice size and pump compatibility; typical upper limit is 500 mPa·s with standard peristaltic feed. For higher-viscosity feeds (>1000 mPa·s), optional high-torque pumps and heated feed lines are recommended.
Is the unit compliant with USP <1151> or ICH Q5C guidelines?
While the instrument itself is not pharmacopeial-certified, its temperature precision, material compatibility, and data logging capability enable method development aligned with USP <1151> (Drying) and ICH Q5C (Stability Testing of Biotechnological Products).
Can it process chlorinated or fluorinated solvents?
Yes—provided appropriate ventilation, explosion-proof electrical components (optional upgrade), and corrosion-resistant seals are specified. Consult factory for solvent compatibility matrix prior to operation.
What maintenance intervals are recommended for the integrated air compressor?
Compressor service is required every 2000 operating hours: filter replacement, desiccant regeneration, and diaphragm inspection. Full service kits and OEM spare parts are available under Anyan P/N 3000YL-COMP-MAINT.
Does the system support IQ/OQ documentation packages?
Yes—Anyan provides customizable Installation Qualification (IQ) and Operational Qualification (OQ) templates, including calibration certificates for PT100 sensors and airflow anemometers, traceable to NIST standards.
