Yacheng YC-2000 Laboratory-Scale Vacuum Spray Dryer

Overview

The Yacheng YC-2000 Laboratory-Scale Vacuum Spray Dryer is an engineered solution for the gentle, solvent-free drying of thermolabile compounds under controlled low-temperature and reduced-pressure conditions. Unlike conventional atmospheric spray dryers—which rely on high inlet air temperatures (often >120 °C) and induce thermal degradation—this system operates within a sealed vacuum chamber where boiling points are significantly depressed. By combining vacuum-assisted evaporation with two-fluid nozzle atomization, the YC-2000 enables rapid moisture removal at process temperatures as low as 60 °C, preserving structural integrity, enzymatic activity, immunogenicity, and volatile compound profiles in sensitive biologics, natural product extracts, probiotics, polymeric nanoparticles, and heat-labile APIs.

Key Features

• Vacuum-integrated spray drying architecture: Chamber pressure maintained between −0.05 and −0.06 MPa to lower solvent boiling points and minimize thermal stress during droplet-to-particle transition.
• PID-controlled heating system with ±1 °C accuracy across the full operational range (60–80 °C), ensuring reproducible thermal input and batch-to-batch consistency.
• Integrated oil-free diaphragm air compressor (imported) eliminates risk of hydrocarbon contamination and complies with ISO 8573-1 Class 0 air purity requirements for pharmaceutical and biotech applications.
• Two-fluid stainless steel nozzle assembly (316L construction) with interchangeable orifices (0.5–2.0 mm) supports precise control over droplet size distribution and final powder morphology.
• Automatic needle-type nozzle cleaner (“clearing pin”) with adjustable frequency prevents nozzle clogging during continuous operation with viscous or particulate-laden feeds.
• Full stainless steel (304/316L) wetted parts conform to ASME BPE surface finish standards (Ra ≤ 0.8 µm) and support clean-in-place (CIP) compatibility for regulated environments.
• Color LCD touchscreen interface with real-time parameter logging, alarm history, and user-accessible calibration menus—designed for GLP-compliant documentation workflows.

Sample Compatibility & Compliance

The YC-2000 is validated for processing aqueous and organic solvent-based solutions containing heat-sensitive actives—including but not limited to live bacterial cultures, monoclonal antibody formulations, plant-derived glycosides, polysaccharide-protein conjugates, and thermally unstable polymers such as PLGA and chitosan derivatives. Its vacuum operation mitigates oxidation pathways and suppresses Maillard reactions common in high-sugar botanical extracts. While the instrument itself does not carry CE, UL, or FDA 510(k) certification, its design aligns with key elements of ISO 22000 (food safety), ICH Q5C (biopharmaceutical stability), and USP (sterile processing considerations). All electrical components meet IP54 ingress protection ratings; noise emission remains below 55 dB(A) at 1 m—within ISO 15712-1 laboratory ambient limits.

Software & Data Management

The embedded control software records time-stamped values for chamber temperature, vacuum level, feed rate, inlet/outlet air differential, and compressor status at user-defined intervals (1–60 s). Data export is supported via USB 2.0 to CSV format for integration into LIMS or statistical process control platforms. Audit trail functionality includes operator login ID, parameter change logs, and system event timestamps—enabling alignment with FDA 21 CFR Part 11 requirements when deployed with supplementary electronic signature protocols. Firmware updates are performed offline via encrypted firmware image files to maintain system integrity and prevent unauthorized modification.

Applications

• Stabilization of live probiotic strains (e.g., Lactobacillus, Bifidobacterium) into inhalable or oral powder dosage forms without loss of viability.
• Drying of enzyme solutions (e.g., lipases, proteases) while retaining >90% residual activity post-processing.
• Production of amorphous solid dispersions from poorly water-soluble APIs co-dissolved with PVP or HPMC in ethanol/water mixtures.
• Rapid generation of reference standards from herbal extract concentrates (e.g., ginsenosides, curcuminoids) with minimal degradation or epimerization.
• Scale-down modeling for clinical-stage spray-dried inhalation (SDI) formulation development under GMP-like engineering controls.

FAQ

Can the YC-2000 operate under inert gas purging (e.g., N₂) in addition to vacuum mode?

Yes—the chamber includes dual-port gas inlet/outlet fittings compatible with nitrogen or argon sparging to further suppress oxidative degradation during drying.
Is remote monitoring or Ethernet connectivity supported?

No native Ethernet or Wi-Fi interface is included; however, analog voltage outputs (0–10 V) are available for external SCADA integration of core parameters.
What maintenance intervals are recommended for the integrated air compressor?

The oil-free diaphragm compressor requires no scheduled lubrication; filter replacement is advised every 1,000 operating hours or annually—whichever occurs first.
Does the system support automated cleaning validation protocols?

While no built-in CIP cycle is implemented, the fully drainable chamber geometry and smooth-welded internal surfaces allow manual rinse verification per ASTM E3061-16 guidelines.
Are spare nozzles and cleaning needles supplied with initial purchase?

One set of three nozzles (0.7 mm, 1.0 mm, 1.5 mm) and two cleaning needles are included as standard; additional consumables are available under part numbers YC-NZL-XXX and YC-CPN-01.
