Geliss Large-Scale Industrial Freeze Dryer with In-Situ Stoppering Capability

The ZLGJ-300F is widely used in fields such as pharmaceutical production, the manufacture of high-end nutritional supplements, large-scale scientific research, and precision sample preparation. In pharmaceutical applications, the equipment supports the freeze-drying of injectables, active pharmaceutical ingredients (APIs), antibodies, and diagnostic reagents; its hydraulic stoppering system and patented welded shelf design effectively ensure sterility, product uniformity, and production efficiency. It is also suitable for the large-batch freeze-drying of peptides, probiotics, and other active ingredients, preserving their nutritional value and biological activity throughout the processing cycle. For universities, contract research organizations (CROs), and research institutes, the system provides a reliable platform for process optimization, pilot-scale studies, and high-capacity sample storage. In analytical and quality control environments, it facilitates the preparation, aseptic sealing, and long-term preservation of large-volume freeze-dried samples, thereby ensuring the accuracy and reliability of test results.

 Frequently Asked Questions

---

Q: How does the patented welded-shelf design facilitate mass production?
A: The design ensures exceptional flatness and durability; it eliminates dead zones where residues could accumulate, making cleaning easy. The shelves do not deform even under prolonged, heavy-load operation, ensuring uniform heat distribution across all vials.
Q: Can this high-capacity freeze dryer operate without a chilled water unit?
A: Yes. The unit features a dual-compressor air-cooled system that dissipates heat directly into the ambient air, requiring only a well-ventilated environment. It is an ideal choice for production facilities that lack chilled water piping infrastructure.
Q: What is the batch capacity for 2ml vials?
A: It can process 7,050 vials per batch. This demonstrates true high-capacity freeze-drying capability, making it perfect for small-scale batch production requiring the processing of thousands of vials at once.
Q: Is the silicone oil circulation system safe for injectable products?
A: It is absolutely safe. The circulation loop is completely sealed and does not come into contact with the product. The system uses low-viscosity, food-grade silicone oil, posing no risk of contamination. Many customers use this industrial-grade freeze dryer to produce sterile injectables.
Q: What validation documentation is included with the equipment?
A: It includes material certificates, welding records, surface roughness reports, IQ/OQ (Installation Qualification/Operational Qualification) protocols, and calibration certificates. We fully support you in meeting global GMP and FDA compliance requirements.
