Description

The YR06692  Silicone Oil Freeze Dryer is a professional-grade vacuum freeze-drying unit designed for high-precision in-situ processing. This equipment stands out due to its advanced silicone oil heating system, which ensures stable and uniform thermal transfer, making it ideal for critical applications in medicine, pharmaceuticals, biological research, and fine chemistry.

This model features an integrated top-press (stoppering) system, specifically engineered for drying vials. Once the process is complete, the device allows for the hermetic sealing of caps within the vacuum chamber, effectively preventing secondary contamination and moisture re-absorption. It is the definitive solution for laboratories and pilot plants requiring automated drying and sublimation with standardized, repeatable results.

Design and Technology (or Functionality)

The YR06692  incorporates patented innovations to optimize every stage of the freeze-drying cycle:

• Silicone Oil Heating Technology: Utilizes fuzzy control technology to ensure minimal temperature deviation between shelves, resulting in superior drying uniformity.
• FD-PILOT System & Touch Screen: Features a 7-inch industrial true-color touch screen with an SH-HPSC-II modular controller. It can store hundreds of process recipes, each containing up to 50 temperature control segments.
• Acrylic Drying Chamber: Equipped with a high-resistance, colorless, and transparent acrylic door that allows for full observation of the material throughout the process.
• Cascade Refrigeration: Powered by internationally renowned compressors in a dual-machine cascade setup, achieving ultra-low temperatures with high efficiency and low noise.
• Intelligent Vacuum Control: Vacuum levels can be adjusted during the drying process to prevent foaming or “blow-out” of specialized materials.
• Data Management: An intelligent data logging system records and displays real-time curves for cold trap temperature, sample temperature, and vacuum levels, exportable via USB for process validation.

Frequently Asked Questions (FAQ)

• What does “in-situ” freeze-drying mean? It means that pre-freezing and drying occur within the same chamber. This eliminates the need for manual material handling between stages, reducing the risk of contamination and thermal loss.
• What is the purpose of the safety diaphragm valve? It allows for the introduction of inert gases (such as Nitrogen) after drying. This is essential for oxygen-sensitive materials that require long-term stable storage.
• Is it suitable for bulk materials? Yes, it is versatile enough to handle bulk liquids, pastes, and solids in trays, as well as bottled products in vials that require vacuum stoppering.

Advantages and Disadvantages

Advantages:

• Full Automation: Seamlessly manages everything from pre-freezing to vial sealing.
• Thermal Precision: Silicone oil provides stability and uniformity that conventional electric heating cannot match.
• Flexible Operation: Offers both Manual mode (for R&D and process development) and Automatic mode (for batch production).
• Reliable Documentation: Comprehensive data logging and multi-level password management for process traceability.

Disadvantages:

• Footprint and Weight: As a robust industrial unit, it requires significant floor space and a solid infrastructure.
• Maintenance Requirements: Cascade refrigeration systems and silicone oil circuits require specialized maintenance compared to basic laboratory models.

Field Use and Recommendations

This equipment is highly recommended for biotechnology plants, pharmaceutical laboratories, and high-end food research centers. It is particularly effective for preserving bacterial strains, sera, vaccines, and sensitive natural extracts.

Pro Tip: To maximize the equipment’s lifespan, perform regular sensor calibration via the control menu and ensure the cold trap is completely defrosted and dry before starting a new cycle to maintain maximum ice-catching capacity.
