SY-20F R&D-Standard

The pilot-scale freeze dryer (R&D) in this series replicates the functionality of production-scale freeze dryers, making it suitable for optimizing industrial freeze-drying parameters. It can be used for process scale-up, approaching production-scale parameters. Whether in early-stage research and development or later in the process scale-up phase, it can provide high-performance process parameters.

Product Advantage


1. Meeting Special Sample Process Requirements:

In the fields of pharmaceuticals, life sciences, and specialized materials freeze-drying applications, some products have critical temperature values Te, Tm, Tc, Tg1 that are lower, even below the control values of pre-freezing and sublimation in conventional freeze dryers. SONYAN Freeze Dryer achieve breakthroughs in special sample freeze-drying by employing targeted structural design, functional upgrades, and process optimizations at the equipment level.

2. Compliance with Relevant Standards such as GMP:

The entire range of SONYAN Freeze Dryer uses a self-developed and copyright-protected drying machine control system, which offers user-friendliness and usability. The reliable FAD-LAB, FAD-EMB, FD-PILOT, LYO-CONTROL control systems, along with the LYO-MEGA remote control system, ensure smooth freeze-drying process compliance with requirements such as the U.S. FDA CFR PART 11 and updated GMP standards.

3. Professional Tray and Cold Trap Technology Production for Uniform Drying:

SONYAN Freeze Dryer employ specialized tray and cold trap technology production to ensure uniform drying results. The stable control system and user-friendly operation facilitate process optimization and drying effect verification.

4. Heating and Cooling Rates Up to 1°C/minute, Matching Industrial Freeze Dryers.

5. The topmost tray functions as a thermal radiation layer to ensure uniform heating across all trays.

6. Contact materials with the samples are made from high-quality stainless steel, and internal components are easy to clean.

7. Utilizes the same PLC system as industrial freeze dryers, offering ample control for various processes and ensuring process repeatability.

8. Capability to design, load, and store process programs, real-time recording of freeze-drying processes, generating freeze-drying curves, reports, historical records, alarms, and more.

Product Uses


Freeze-drying process optimization is suitable for various industries, including biotechnology, pharmaceuticals, materials science, chemical engineering, and food production.


Product Operate Guide


The control system of this machine features a large touchscreen, providing convenient, straightforward operation with powerful functionality. Each screen displays a wealth of data in an intuitive and clear manner. It can store hundreds of temperature control programs, with each program allowing for the configuration of up to 36 segments.

Advanced fuzzy PID control algorithms ensure precise and stable temperature control. During automatic temperature control, you can modify temperature parameters and skip segments as needed, offering flexibility in operation. The system controls shelf temperatures according to pre-set parameters. Multiple stability measures are incorporated into the system, ensuring stable and reliable operation.


FAQ


1. Why is my freeze dryer experiencing leaks during the freeze-drying process?

· Check the seals of the equipment, such as doors and valves, to ensure they are intact and properly closed.

· Inspect the vacuum system for leaks. You can use tools like a helium leak detector to pinpoint leak locations.

· If the issue persists, contact technical support for further diagnostics and repairs.


2. How do I clean and maintain my freeze dryer?

· Turn off the equipment's power and ensure all components have cooled down.

· Clean the internal and external surfaces using a mild cleaning agent and a soft cloth.

· Regularly change the vacuum pump oil and perform other maintenance procedures per the manufacturer's recommendations.

· Clean and maintain critical components like the cold trap, vacuum lines, and valves.


3. Why is the freeze-drying time for my freeze dryer longer than expected?

· It may be due to larger sample sizes or higher initial moisture content. Adjust the freeze-drying program accordingly based on specific circumstances.

· Ensure the vacuum pump and condenser are performing well to achieve the desired vacuum levels quickly.

· You can try increasing the freezing temperature and vacuum level to expedite the freeze-drying process.
