Geliss Pilot-Scale Silicone Oil Heated Peptide Freeze Dryer

1. Air-Cooled Efficient Refrigeration, Stable and Energy-Saving

Adopting two imported TECUMSEH full-closed compressors from France, one for shelf indirect refrigeration and the other for condenser direct refrigeration, with environmental protection refrigerant. The air-cooled cooling method is adopted, which is easy to install without additional water cooling equipment, saving installation space and operation costs. The temperature drop speed of the condenser is fast, which can drop from +20℃ to -40℃ within 30 minutes, ensuring efficient and stable operation of the freeze-drying process.

2. Natural Defrosting, Convenient Operation and Maintenance

The condenser adopts a cylindrical compact design, made of AISI 304 stainless steel, with strong ice capture capacity and easy cleaning. It adopts natural defrosting mode, which is simple to operate, no need for manual intervention, and avoids the risk of cross-contamination caused by manual defrosting. The condenser can capture more than 8Kg of ice, which can fully meet the water capture needs of small-to-medium batch production.

3. Multi-Specification Vial Compatibility, High Production Efficiency

Equipped with 4+1 layers of shelves (with a radiation layer), the shelf spacing is 70mm, and the effective shelf size is 365mm×485mm. It is compatible with ￠12 (2ml), ￠16 (5ml), ￠22 (10ml) vials, with loading capacities of ≥4246, ≥2388, and ≥1263 respectively. It can efficiently complete the freeze-drying production of various specifications of materials, and the shelf temperature difference is ≤±1℃ when balanced, ensuring uniform freeze-drying effect of materials.

4. Integrated Compact Structure, Easy Transportation and Placement

The whole machine adopts an integrated structure, with overall dimensions of about 960×785×1450mm and a weight of about 447Kg, which is small in size and easy to transport and place. The body is made of high-quality materials, with polyurethane foam insulation, good thermal insulation effect, and can effectively reduce energy consumption. The acrylic door is convenient for observing the freeze-drying process of materials in real time.

5. Compliant and Durable, Cost-Controllable

The drying chamber and shelves are made of AISI 304 stainless steel, with a surface roughness of Ra ≤0.6μm, which is easy to clean and disinfect, meeting GMP compliance requirements. The core components such as expansion valve and solenoid valve are selected from international well-known brands such as Danfoss, ensuring the durability and stability of the equipment. The installed power is 5.5KW (not the operating power), and the energy consumption is low, which can effectively control the long-term operation cost.

Application Fields

ZLGJ-50F is widely used in small-to-medium batch production and scientific research experiments, covering multiple fields:

• Biomedicine: Suitable for freeze-drying of diagnostic reagents, common vaccines, and small-molecule drugs, compatible with various specifications of vials, meeting the requirements of GMP compliant batch production and pilot test verification.

• Food Processing: Used for freeze-drying of ordinary fruits and vegetables, dried meat, and traditional snacks, retaining the original nutrition and flavor of materials, and adapting to small-batch production needs of food factories.

• Scientific Research: Providing stable and reliable equipment for university laboratories and research institutes, suitable for sample preparation, process exploration, and multi-batch comparative experiments.

• Fine Chemicals: Suitable for drying heat-sensitive chemical raw materials, additives, and other materials, avoiding component degradation caused by high temperature, and ensuring product quality.
