LGJ-30FG Silicone Oil Square Chamber Freeze Drying MachineProduct Usage

Vacuum freeze dryers are widely used in fields such as medicine, pharmaceuticals, biological research, chemical engineering, and food. Items that have undergone freeze-drying treatment are easy to store for a long time, and can be restored to their pre freeze-drying state and maintain their original biochemical characteristics after adding water.

LGJ-30FG Silicone Oil Square Chamber Freeze Drying MachineKey Features:

• The transparent door of the drying chamber is made of aviation acrylic material, which is non adhesive, high-strength and leak freeCan clearly observe the changes in materials during the operation process.

• ImportBrand compressor, stable and low noise.

• Brand vacuum pump, with high pumping speed and low noise.

• Pre freeze-drying is carried out in situ, reducing the tedious operation of the drying process and achieving automation of the freeze-drying process;

• Silicone oil, as a circulating medium, has high temperature control accuracy, shelf temperature difference ≤ 1 ℃, and uniform drying effect;

• shelfPre freezingTemperature adjustable, controllable, exploratory, pilot and production processes;

• Can store moregroupProgram, each program can be programmed to set the pre freezing section and drying section. The freeze dryer can modify program parameters and record the drying curve during operationAnd data；

• 7-inch touch screen operation, PIC industrial controller, displaying drying curve;

• Square pallets are not easily deformed, easy to operate, and easy to clean;

• Configure an inflation valve that can be filled with dry inert gas;

• User level and password can be set, and operation management can be decentralized;

• Nitrogen or inert gas can be filled for storage after drying.

• Freeze drying automatic control system:

• Board layer heating control system:

Thermal cycle protection, special heating materials, fuzzy PID control algorithm.

The freeze-drying curve optimization control algorithm can control the sample heating rate and current vacuum degree value during the sublimation and analytical drying stages.

• Vacuum regulation system:

Vacuum degree adjustment is carried out during sublimation and analytical drying processes to avoid problems such as foaming of special substances, bottle blowing, and accelerated freeze-drying efficiency.

Adopting an industrial touch screen, it has good human-computer interaction, is simple and easy to understand, and can be operated easily without the need for instructions.

• Manual automatic mode selection:

Manual mode is used to explore process parameters (with strong human intervention), while automatic mode is used in the mature stage of the process, with one click operation, simple and convenient.

• Data recording system:

External storage (USB flash drive), the amount of data stored is related to the capacity of the USB flash drive

PC database storage, the amount of stored data is related to the available capacity of the computer's hard drive(Optional).

• Defrosting method:

Cold trap electric defrosting improves defrosting speed and safety through two control modes: temperature and time;

• Optional features (additional charge)：

PC(Computer) endRemote monitoring of device operation status, with a monitoring distance of 1.5KM (optional)Print freeze-drying curves and data(Optional)；

Eutectic point testing function (optional)；

10 inch large color screen for easier device operation(Optional)；

Imported brand vacuum pump(Optional)；

Water cooled condensation, more stable temperature not affected by ambient temperature(Optional)；

Calibration function:

Temperature and vacuum calibration can be performed to ensure the long-term use of measured values.

Freeze drying curve query function (can query temperature and vacuum degree curves, convenient for process optimization and freeze-drying effect verification).
