Product Introduction

The ZLGJ-20F silicone oil-heated vacuum freeze dryer is a cost-effective pilot-scale unit featuring sealed silicone oil circulation heat transfer technology and a compact, integrated design. It is equipped with an original French Tecumseh hermetic dual-compressor system and a Japanese Mitsubishi PLC control system. The unit offers a freeze-drying area of ​​0.3 m² and utilizes a patented 3+1 shelf configuration with internally welded channels; the cold trap achieves a minimum temperature of ≤-75°C and a water-trapping capacity exceeding 4 kg. Manufactured in strict accordance with GMP and GB/T5226.1-1996 standards, the equipment is suitable for pilot-scale validation, small-batch trial production, and scientific research and education in fields such as biopharmaceuticals, food processing, and new chemical materials. This silicone oil-based freeze dryer is characterized by precise temperature control, stable operation, and ease of maintenance.

Core Advantages

The system utilizes a closed-loop heat transfer circuit with low-viscosity silicone oil and is equipped with an original Grundfos canned motor pump, ensuring uniform heat exchange across the entire area; shelf temperature uniformity is maintained within ±1°C (at equilibrium), effectively preventing issues such as uneven freeze-drying and inconsistent product quality. The shelves are constructed from AISI 304 stainless steel using the company's patented internal welding technology, achieving a surface roughness of Ra ≤ 0.6 μm and flatness within ±0.5 mm/m; this design eliminates sanitary dead zones, facilitates cleaning and sterilization, and fully complies with clean production requirements in the biopharmaceutical industry. Shelf temperatures are flexibly adjustable between -50°C and +70°C (no-load), with controllable ramp rates (cooling from +20°C to -40°C and heating from -40°C to +20°C both take ≤ 60 minutes); the closed-loop temperature control system ensures a stable freeze-drying curve and excellent process reproducibility. The cylindrical cold trap cools from +20°C to -40°C within 30 minutes, reaches a minimum temperature of ≤ -75°C, and offers a water-trapping capacity exceeding 4 kg; a high-pressure defrost function enables rapid, thorough defrosting, significantly shortening the freeze-drying cycle while effectively preserving the activity and nutritional value of heat-sensitive materials.
