Product Overview
The ZLGJ-20FY silicone oil-heated vacuum freeze dryer with automatic stoppering is a high-performance pilot-scale unit designed for pilot-scale R&D, small-batch production, and high-precision sample processing. It integrates core technologies such as precise silicone oil temperature control and high-pressure, high-efficiency defrosting, and is equipped with genuine French Tecumseh hermetic compressors (dual-unit system), a Yonghao two-stage rotary vane pump, and a Ruibao high-precision vacuum gauge. Featuring a freeze-drying area of 0.2 m², it utilizes a patented"2+1"shelf configuration (employing internal welding technology); the cold trap achieves a minimum temperature of ≤-75°C and a water-trapping capacity exceeding 4 kg. Manufactured in strict accordance with GMP, FDA, and GB/T5226.1-1996 standards, the unit is easy to operate and transport, making it an ideal choice for pharmaceutical companies, research institutes, and testing organizations requiring pilot-scale freeze-drying and aseptic stoppering capabilities.
Key Features
The system utilizes advanced, precision silicone oil temperature control technology and is equipped with an original Grundfos canned motor pump for silicone oil circulation, ensuring uniform shelf temperature distribution with a deviation of ≤±1°C (under equilibrium conditions). Under no-load conditions, the shelves can transition from -40°C to +20°C and from +20°C to -40°C within 60 minutes, thereby better protecting heat-sensitive materials—such as proteins and peptides—and ensuring consistent product quality across batches.

Application Fields
This equipment is frequently used by pharmaceutical companies for process validation and pilot-scale production of freeze-dried injectables and biological products; leveraging precise silicone oil temperature control technology and pilot-scale batch freeze-drying capabilities, it provides reliable data support for large-scale production.
Frequently Asked Questions
Q: How long does the high-pressure defrosting process take?
A: Typically, the ice layer can be completely removed within 10 to 15 minutes. In contrast, natural defrosting takes hours, while manual ice removal is not only time-consuming (taking about 30 minutes) but also carries the risk of damaging the equipment. Therefore, this high-pressure freeze dryer is an ideal choice for busy pilot-scale facilities.
Q: Is the silicone oil used for heat transfer safe for pharmaceutical products?
A: Yes. The equipment utilizes a closed-loop circulation system, ensuring that the silicone oil never comes into direct contact with the product. The system employs low-viscosity, food-grade silicone oil and features a fully sealed design, thereby eliminating any risk of contamination.
Q: Can vials of different specifications be processed in the same batch?
A: Yes, though we recommend processing them in separate batches for optimal results. The equipment is equipped with a manual stoppering handle that allows for the adjustment of stoppering force based on the vial type; the shelf spacing is also adjustable (up to a maximum of 100mm) to accommodate taller vials.
Q: Does the equipment come with validation documentation?
A: Yes. Each pilot-scale freeze dryer ships with test reports, IQ/OQ (Installation Qualification/Operational Qualification) protocols, and material certificates to fully meet your GMP and FDA audit requirements.
Q: What is the typical delivery lead time?
A: Standard models can be shipped within 4 to 6 weeks. Customized configurations (such as specific voltages, shelf spacing, or additional sensors) may require an extra 2 to 3 weeks. Additionally, we offer expedited service options for existing customers.
