304 Stainless Steel PLC Controlled Industrial Freeze Dryer with 50㎡ Shelf Area
The SF-50S-304 is a premium industrial vacuum freeze dryer engineered with a fully 304 stainless steel chamber and shelf assembly, designed for high-capacity high-end collagen, biotech, and chemical lyophilization. With 1~50㎡ effective shelf area and PLC automated control, this lyophilizer delivers unmatched reliability, corrosion resistance, and process precision.
- 304 Stainless Steel Construction: All product-contact surfaces including drying chamber, shelves, and vapor condenser are fabricated from food-grade 304 stainless steel, ensuring exceptional corrosion resistance and GMP compliance.
- PLC Automated Control System: 10-inch color touch screen with recipe storage for up to 30 freeze-drying programs. Real-time monitoring of shelf temperature, product temperature, vacuum level, and cold trap status.
- 1~50㎡ Shelf Area: 12 stainless steel shelves provide 50 square meters of total drying area, capable of processing up to 500kg of product per batch (depending on product characteristics).
- Wide Temperature Range: Shelf temperature adjustable from -50℃ to +70℃, suitable for both freeze-drying and secondary drying phases.
- High-Efficiency Cold Trap: ≤ -55℃ condenser temperature with 500kg/24h ice capacity, ensuring efficient vapor capture and stable vacuum.
- Silicone Oil Heating System: Uniform shelf heating via silicone oil circulation for precise temperature uniformity across all shelves.
- Ultimate Vacuum ≤ 10 Pa: Two-stage rotary vane vacuum pump with gas ballast, achieving deep vacuum rapidly and maintaining stability throughout the cycle.
