Vacuum freeze dryer LGJ-200FG

Key Features:

ØThe 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.

ØImported brand compressor, stable and low noise.

ØBrand vacuum pump, with high pumping speed and low noise.

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

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

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

ØShelf pre freezing temperature adjustable, controllable, explorable, pilot and production process；

ØThe 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;

Østorable1000 sets of programs, each with programmable settings for pre freezing and drying sections. The freeze dryer can modify program parameters during operation and record drying curves and data;

Ø7-inch touch screen operation, PLC industrial controller, displaying drying curve;

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

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

ØUser level and password can be set, and operation management can be decentralized;

ØNitrogen or inert gas can be filled for storage after drying.

ØFreeze drying automatic control system:

ØBoard 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 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.

ØManual 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.

ØData recording system:

An intelligent data recording system that records real-time operational data of each component and generates curves, and can export data for browsing, printing, and various operations on a computer, facilitating process optimization and drying effect verification;

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

ØDefrosting method:

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

ØOptional 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 samples, can be backfilled 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)；

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 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).
