1. The shelves incorporate our innovative technology, utilizing a circulating heat transfer fluid within them. This unique design allows for in-place refrigeration or heating, resulting in uniform temperature distribution and easy temperature control. As a result, these shelves serve as highly efficient conductors.
2. Our independently researched and developed PLC system enables seamless automatic control or semi-automation functionalities.
3. Equipped with:
1) A 10" touch screen:
- Record and present real-time data. Get an at-a-glance view of live readings, including vacuum pressure, cold trap temperature, and material and shelf temperatures. These readings collectively construct the freeze-drying curve;
- Data-saving frequency: every minute;
- Efficiently capture and continuously monitor comprehensive data on the material and the freeze dryer’soperational status;
- Off-linedata is available for analysis, printing, and storage;
2) USB ports.
4. A distinctive design sets this system apart: the segregation of the vacuum chamber and the cold trap effectively eliminates any adverse effects of the cold trap temperature on material sublimation. Consequently, this speeds up the sublimation process and enhances the dehumidification capacity. This design enables the biopharmaceutical industry to delve into freeze-drying processes, with the potential for scaling up production in the future.
5. Real-time monitoring of vacuum pressure is implemented to safeguard the integrity of the vacuum system. If the vacuum pressure fails to reach the designated setpoint within the stipulated timeframe, an automatic shutdown of the vacuum pump is triggered. Subsequently, the solenoid valve is activated to allow air ingress, thereby maintaining the shelves’ temperature at a normal level under atmospheric pressure conditions. The vacuum pressure chamber functions like an Ultra-Low Temperature (ULT) freezer, offering enhanced protection for the samples.
6. The refrigeration system is bolstered by two hermetic compressors, which are interconnected, with one compressor responsible for refrigerating the other. This compressor unit utilizes environmentally friendly refrigerants that adhere to international safety standards. These combined features facilitate rapid refrigeration. The cooling system is stable, with low vibration and low noise.
7. The compressor incorporates a restart delay mechanism, and an integrated thermal overload module is employed to safeguard the freeze-dryer from overheating.
8. A distinctive design incorporates a silicone oil-based heat transfer mechanism, making the shelves achieve higher temperature control accuracy.
9. A gas inlet is incorporated into the system (operating under negative pressure in the vacuum chamber). The gas inlet is equipped with a Ø0.2µm filter, allowing for the introduction of inert gases like nitrogen. This addition serves to effectively prevent therecontamination of samples.
10. A molded T-structure is embedded in the vacuum chamber door and the cold trap, preventing leaks resulting from warped doors and enhancing their sealing capabilities.
11. Consider incorporating a valve to regulate the vacuum pressure, as this addition also facilitates in-depth exploration of the freeze-drying process.
12. Consider implementing Wi-Fi and wireless IoT receivers, enabling users to achieve remote control through their mobile phones and receive real-time alarms on WeChat.
13. Access the cumulative operating hours of the vacuum pump, serving as a reliable indicator to determine the optimal timing for changing the vacuum pump oil, beneficial to extend the equipment’s service life.
14. Able to detect an endpoint in a lyophilization process.
15. Distinct user access levels, categorized into three tiers. Each account is equipped with its unique password to securely log onto the platform. Comprehensive information, including user login history, activities, freeze-drying data/curves, and alarm records, is meticulously tracked and recorded. Users have the capability to directly export freeze-drying curves and generate datasheets in PDF format.
16. The freeze-dryer can store up to 50 recipes, which can be customized with different names. Each recipe offers 36 temperature control stages, and for each of these stages, individual time settings can be configured. The freeze-dryer intelligently waits until the specified time reaches its setpoint before initiating the countdown. During any given stage, it allows for real-time data modification, and the system automatically adjusts the time spent on sublimation based on the changes made.
17. The IoT technology seamlessly integrates with the PC, enhancing the freeze-dryer with advanced data processing and online communication capabilities beyond the PLC system. This empowers the freeze-dryer to perform more intricate calculations and provides virtually unlimited storage capacity.
18. The casing is constructed with 304 stainless steel, complying with the GMP standards for cleanrooms in the biopharmaceutical industry. An installation plan is also provided.
