Applications
Vacuum freeze dryers are widely used in medicine, pharmaceuticals, biological research, chemical engineering, and food processing. Freeze-dried items are easy to preserve for long periods and can be restored to their pre-freeze-drying state after adding water, maintaining their original biochemical properties.
Main Features
Ø The transparent door of the drying chamber is made of aerospace-grade acrylic material, which is non-adhesive, high-strength, and leak-proof, allowing clear observation of the material’s changes during operation.
Ø Imported brand compressor, stable and low noise.
Ø Branded vacuum pump, high pumping speed and low noise.
Ø Pre-freeze-drying is performed in situ, reducing cumbersome operations in the drying process and automating the freeze-drying process;
Ø A simulated operation window interface visually reflects the operating status of each component, displaying current operating parameters in digital form;
Ø Silicone oil is used as the circulating medium, ensuring high temperature control accuracy, with shelf temperature difference ≤1℃ and uniform drying effect;
Ø Shelf pre-freezing temperature is adjustable, controllable, and can be explored, used in pilot-scale and production processes;
Ø The separate design of the freeze-drying chamber and cold trap cavity achieves pharmaceutical-grade pilot-scale machine standards while significantly improving water capture efficiency and capacity;
Ø It can store 1000 programs, each with programmable pre-freezing and drying sections. Program parameters can be modified during freeze dryer operation, and drying curves and data can be recorded;
Ø 7-inch touchscreen operation, PLC industrial controller, displaying drying curves;
Ø Square trays are not easily deformed, easy to operate, and easy to clean;
Ø Equipped with an inflation valve for filling with drying inert gas;
Ø User levels and passwords can be set for hierarchical operation management.
Ø It can be stored after drying using nitrogen or inert gas.
Ø Freeze-drying automatic control system:
Ø Plate heating control system:
Thermal cycle protection, special heating materials, and fuzzy PID control algorithm.
Freeze-drying curve optimization control algorithm, which can control the sample heating rate during sublimation and desorption drying stages.
Equipped with an industrial touch screen, it offers excellent human-machine interaction, is simple and easy to understand, and can be operated without a manual.
Ø Manual/Automatic mode selection:
Manual mode is used for exploring process parameters (high degree of human intervention), while automatic mode is used for the mature stage of the process. One-button operation is simple and convenient.
Ø Data recording system:
Intelligent data recording system records the operating data of each component in real time and generates curves. Data can be exported for viewing, printing, and various operations via computer, facilitating process optimization and verification of drying effects.
PC database storage; the amount of data stored is related to the available capacity of the computer’s hard drive (optional).
Ø Defrosting Method:
Cold trap electric defrosting, with both temperature and time control modes, improves defrosting speed and safety.
Ø Optional Functions (additional charges apply):
Vacuum Regulation System: Adjusts vacuum during sublimation and desorption drying processes to avoid bubbling, bottle blowing, and accelerate freeze-drying efficiency issues associated with special substances. Optional negative pressure gas mixing system interface with built-in 0.2μm filter to reduce secondary sample contamination; can be backfilled with nitrogen or inert gas. (Optional)
Remote monitoring of equipment operation via PC, up to 1.5KM (optional);
Printing freeze-drying curves and data (optional);
Eutectic point testing function (optional);
Freeze-drying endpoint determination (optional);
10-inch large color screen for easier equipment operation (optional);
Imported brand vacuum pump (optional);
Water-cooled condensation for more stable temperature unaffected by ambient temperature (optional);
Calibration Function
Temperature and vacuum calibration ensures the accuracy of measurements over long-term use.
Freeze-drying curve query function (allows querying temperature and vacuum curves for convenient process optimization and freeze-drying effect verification).
