GMP Freeze Dryer — SJ Scientific freeze dryer series

GMP Freeze Dryer

SJIALAB GMP freeze dryers are built for pharmaceutical freeze drying workflows from process development and pilot validation through commercial production. The platform combines stable shelf temperature control, reliable vacuum performance, and configurable chamber formats to support scale-up with consistent batch quality. Our systems are suitable for vial and bulk lyophilization, with optional SCADA integration and 21 CFR Part 11-ready data workflow support. Typical projects include sterile injectables, biotech intermediates, peptides, proteins, and other temperature-sensitive products that require repeatable drying performance. If you are comparing GMP lyophilizers for a new facility, pilot line, or production upgrade, this series covers multiple shelf areas and chamber sizes so you can match capacity, automation level, and validation requirements to your process.

Filling, Stoppering & Capping Machines — SJ Scientific freeze dryer series

Filling, Stoppering & Capping Machines

Filling and capping machines are the upstream partner to every freeze dryer. In a typical vial fill-finish process the liquid is dosed, half-stoppered, lyophilized, and then aluminum-capped — and SJ Scientific builds the equipment for each step. As a freeze dryer manufacturer since 2012, we match the right filling technology to your product: tool-free peristaltic pumps for fast changeover and single-use aseptic filling, or valveless ceramic piston pumps for high-precision, corrosion-resistant dosing. Models range from benchtop 2–10 ml units to inline systems running up to 300 vials/min, all built to GMP with 316L product-contact parts. Lower-throughput lines can integrate capping into the filler; higher-throughput lines pair a filling-stoppering machine with a dedicated capper.

H Series Small Food Freeze Dryers — SJ Scientific freeze dryer series

H Series Small Food Freeze Dryers

H-series freeze dryer machines for home, farms, test kitchens, and small food brands cover 5-30 kg reference fresh loads. Compare usable tray area, electrical supply, condenser option, ventilation, and production rhythm before choosing a model.

View Series
Commercial Food Freeze Dryer — SJ Scientific freeze dryer series

Commercial Food Freeze Dryer

Commercial H freeze dryer machines for food provide 30-70 kg reference fresh loads and 2.95-4.98 m2 of tray area. SJ-30H, SJ-35H, and SJ-50H support specialty-food brands, farms, pilot plants, and regular small-factory production before a cart-based FFD line is required.

View Series
Industrial Food Freeze Dryer — SJ Scientific freeze dryer series

Industrial Food Freeze Dryer

FFD industrial food freeze dryer and food lyophilizer systems cover 5-250 m2 of usable shelf area and approximately 50-2500 kg of fresh material per batch. Compact FFD-5 / 10 / 20 models use direct-contact shelves; FFD-50+ platforms use radiant heating with cart-and-tray handling for factory production.
