In situ silicone oil freeze dryer (cover type)

LGJ-300FG/YIn situ silicone oil freeze dryer (cover type)Product 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-300FG/YIn situ silicone oil freeze dryer (cover type)Key Features:

At the bottomThe transparent door of the drying chamber is made of aviation acrylic material, which is non adhesive, high-strength and leak free. During operation, the material changes can be clearly observed.

At the bottomImported brand compressor, stable and low noise.

At the bottomBrand vacuum pump, with high pumping speed and low noise.

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

At the bottomSimulate the running window interface, visually reflect the operating status of each component, and display the current operating parameters of each part in digital form;

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

At the bottomShelf pre freezing temperature adjustable, controllable, explorable, pilot and production process；

At the bottomThe design of separating the freeze-drying chamber from the cold trap chamber not only meets the standards of pharmaceutical grade pilot testing machines, but also greatly improves the water capture efficiency and capacity;

At the bottomstorablemanyGroup program, each program can be programmed to set the pre freezing section and drying section, the freeze dryer can modify program parameters during operation, and record the drying curve and data;

At the bottom10Inch touch screen operation,PLC industrial controller, displaying drying curve;

At the bottomSquare pallets are not easily deformed, easy to operate, and easy to clean;

At the bottomConfigure an inflation valve that can be filled with dry inert gas;

At the bottomUser level and password can be set, and operation management can be decentralized;

At the bottomNitrogen or inert gas can be filled for storage after drying.

At the bottomFreeze drying automatic control system:

At the bottomBoard layer heating control system:

Thermal cycle protection, special heating material, fuzzyPID control algorithm.

Freeze drying curve optimization control algorithm, which can control samples during sublimation and analytical drying stagesofHeating rate.

Adopting industrial touch screen and human-computer interactiongoodOkay, it's easy to understand and can be operated without the need for an instruction manual.

At the bottomManual automatic mode selection:

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

At the bottomData recording system:

Intelligent data recording system, real-time recording of operating data of each component and generating curves, and capable ofexportData can be browsed, printed, and operated through a computer, facilitating process optimization and validation of drying effects;

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

At the bottomDefrosting method:

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

At the bottomOptional features (additional charge):

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.

Optional negative pressure aeration system interface, built-in0.2 μ m filter element, reduces secondary contamination of the sample, can be filled with nitrogen or inert gas;(Optional)

The PC (computer) can remotely monitor the operation status of the equipment, with a maximum monitoring distance of 1.5KM(Optional)，

Print freeze-drying curves and data(Optional)

Eutectic point testing function(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 accuracy of long-term measurement values.

Freeze drying curve query function(Temperature and vacuum curves can be queried for process optimization and freeze-drying effect verification).
