Yacheng YC-015 Benchtop Spray Dryer

Overview

The Yacheng YC-015 Benchtop Spray Dryer is a compact, fully integrated laboratory-scale spray drying system engineered for precision, reproducibility, and operational safety in R&D environments. It employs two-fluid nozzle atomization—where compressed air shears liquid feed into fine droplets—and concurrent-flow hot-air drying within a borosilicate glass drying chamber. This configuration ensures rapid, controlled solvent evaporation with minimal thermal stress on thermolabile compounds. The system operates on the principle of flash evaporation: liquid feed is atomized into micron-scale droplets (1–25 µm), exposed briefly (1.0–1.5 s) to heated air (up to 250 °C), and dried instantaneously before contacting chamber walls. Resulting powders are separated via cyclonic action and collected in a sealed glass vessel, while exhaust air is vented or routed through optional filtration. Designed for standalone operation in ISO Class 7–8 lab spaces, the YC-015 requires no external utilities beyond standard single-phase power and compressed air (internally supplied by a built-in oil-free compressor). Its all-stainless-steel frame (AISI 304/316), high-borosilicate glass components, and PID-regulated temperature control support GLP-compliant documentation and repeatable process development.

Key Features

• Full-color 7-inch LCD touchscreen interface with real-time animated process visualization—including inlet temperature, airflow (fan frequency), peristaltic pump speed, and automatic needle-cleaning (anti-clogging) frequency
• Integrated oil-free air compressor eliminates lubricant contamination risk and maintains consistent atomization pressure
• Two-fluid nozzle system (1.0 mm standard; optional 0.5/0.8/1.5/2.0 mm nozzles) with adjustable atomization air flow and optional three-fluid configuration for viscous or suspension feeds
• Tower-wall air-sweep system enhances powder recovery (>95% collection efficiency) and minimizes wall deposition
• PID-controlled inlet air temperature regulation with ±1 °C accuracy across full 30–250 °C range
• Automatic needle-cleaning mechanism (‘needle purge’) with programmable frequency to prevent nozzle blockage during continuous operation with suspensions or high-solids feeds
• Stainless-steel construction (AISI 316 nozzle, AISI 304 chassis) and borosilicate glass drying chamber, cyclone, and collection vessel—fully autoclavable and compliant with USP and ISO 10993 biocompatibility requirements for material contact surfaces
• Low-noise operation (<60 dB[A]) suitable for shared laboratory environments without acoustic shielding
• Emergency shutdown protocol: pressing STOP halts heating and feed delivery immediately; only exhaust fan continues briefly for safe cooldown—preventing heater coil damage from abrupt airflow cessation

Sample Compatibility & Compliance

The YC-015 accommodates aqueous and organic solvent-based solutions, emulsions, colloidal suspensions, and nano-dispersions—including heat-sensitive biologics (e.g., enzymes, peptides, plasmid DNA), probiotics, vaccines, natural extracts, polymers, and ceramic precursors. Its short residence time and precise thermal management preserve structural integrity and bioactivity, as validated in peer-reviewed studies using model proteins (BSA, lysozyme) and live microbial cultures. All wetted parts meet FDA 21 CFR Part 11 readiness standards when paired with optional audit-trail-enabled software. The system complies with ISO 9001 manufacturing protocols and conforms to IEC 61000-6-3 (EMC) and IEC 61000-6-2 (immunity) for laboratory instrumentation. Optional nitrogen recirculation upgrade enables safe processing of flammable solvents (e.g., ethanol, acetone) under inert atmosphere—meeting OSHA 1910.106 and ATEX Zone 2 requirements when installed per manufacturer guidelines.

Software & Data Management

The embedded microprocessor controller logs all critical parameters (inlet/outlet temperature, pump RPM, fan Hz, needle purge cycles) at 1-second intervals to internal non-volatile memory. Data export is supported via USB port in CSV format for post-processing in MATLAB, Python (Pandas), or statistical analysis platforms (JMP, Minitab). Optional PC-based software provides remote monitoring, multi-user access control, electronic signature capability, and 21 CFR Part 11–compliant audit trails—including user login history, parameter change logs, and timestamped event records. All firmware updates are delivered via encrypted USB key with SHA-256 checksum verification. Calibration certificates traceable to NIST standards are provided with each unit shipment.

Applications

The YC-015 supports formulation development and process optimization across pharmaceuticals (amorphous solid dispersions, inhalable dry powders, nanoparticle carriers), food science (encapsulated flavors, probiotic powders, functional ingredient microcapsules), materials science (metal oxide nanoparticles, battery cathode precursors, MOF powders), and agrochemical research (biopesticide microencapsulation, controlled-release fertilizers). It is widely deployed in academic labs (Tsinghua University, HKUST, ETH Zurich collaborators), CMC departments (Huahai Pharma, GE Healthcare), and contract development organizations (CROs) conducting DOE-based spray drying studies under QbD frameworks. Its scalability enables direct correlation with pilot-scale tower dryers (e.g., Buchi B-290, GEA Minor) using dimensionless numbers (Weber, Reynolds, Droplet Weber).

FAQ

Can the YC-015 handle organic solvents?
Yes—when upgraded with the optional nitrogen recirculation module, it safely processes ethanol, methanol, acetone, and other Class I flammable solvents under inert atmosphere.

What is the minimum sample volume required per run?
The system supports feed volumes as low as 30 mL, depending on solids content and viscosity; optimal yield is achieved with ≥100 mL batches.

Is the glassware autoclavable?
All borosilicate glass components (drying chamber, cyclone, collection bottle) are rated for autoclaving at 121 °C / 2 bar; stainless-steel parts are passivated per ASTM A967.

Does it support GMP documentation?
With the optional software package, it meets ALCOA+ data integrity principles and supports 21 CFR Part 11 compliance, including electronic signatures and audit trails.

Can particle size distribution be tuned?
Yes—via coordinated adjustment of inlet temperature, feed rate, atomization air pressure, and nozzle orifice size; narrow PSD (span <1.5) is routinely achieved for monodisperse polymer microparticles.
