Product Overview

The ZLGJ-300F is designed for large-scale industrial production, high-volume material processing, and high-capacity scientific research. It features an integrated structure, a water-based defrosting function to ensure hygienic operation and maintenance, and high-pressure safety protection technology. The system is equipped with an imported Grundfos canned motor pump and a high-quality low-viscosity silicone oil circulation system, offering a freeze-drying area of ​​3.15 square meters. As a stable and efficient core piece of equipment for sectors such as biopharmaceuticals, food processing, fine chemicals, and scientific research, it fully meets the demands of large-scale production and high-capacity sample preparation.

Core Advantages

This equipment utilizes a unique water-based defrosting technology—distinct from electric heating or natural defrosting methods—that completely removes ice buildup without leaving residue, thereby effectively preventing cross-contamination during production. Its cold trap features rapid cooling and powerful ice-trapping capabilities, capable of lowering the temperature from +20°C to -40°C within 30 minutes; paired with a Yonghao two-stage rotary vane pump, the system can reduce pressure from atmospheric levels to 10 Pa in 30 minutes, ensuring the stability and reliability of the freeze-drying process. The system is equipped with a comprehensive high-pressure safety mechanism (utilizing imported Danfoss high-pressure controllers and protection devices); should the discharge pressure exceed permissible limits, the refrigeration unit automatically shuts down to prevent accidents. Air circuit breakers and intermediate relays integrate reliable logic interlocking and safety protection functions to ensure the equipment operates safely and stably—representing the core value of this high-pressure safety system.

Frequently Asked Questions

Q: What are the advantages of water-flush defrosting compared to electric heating or natural defrosting?
A: Water-flush defrosting is faster and more thorough, leaving no ice residue; it is the cleanest defrosting method for GMP environments. Therefore, this heavy-duty industrial freeze-dryer is specifically equipped with a water-flush defrosting system.
Q: What is the maximum loading capacity for 2ml vials?
A: This production-scale freeze-dryer can accommodate ≥22,290 vials (12mm diameter). It is also compatible with 16mm and 22mm diameter vials, though the loading capacity will decrease accordingly.
Q: Is the equipment difficult to maintain?
A: Not at all. Maintenance involves only cleaning the shelves after each run and checking the vacuum pump oil level weekly. Apart from routine cleaning, the water-flush defrosting system requires no additional maintenance. We provide detailed technical documentation and 24/7 technical support.
Q: Can it be integrated into an existing production line?
A: Yes. Its integrated design accommodates most facility layouts. The equipment dimensions are 850 × 2500 × 1700 mm (excluding the oil tank). We also offer custom configuration services.
Q: What safety certifications does the equipment hold?
A: The equipment complies with CE certification, GMP standards, and the GB/T5226.1-1996 standard, and comes with all relevant test reports and validation documentation.
