LGJ-18S electric heating multi manifold cover freeze dryer electric frost

LGJ-18S electric heating multi manifold cover freeze dryer electric frostDetailed introduction:

LGJ-18S (Electric Heating) Vacuum Freeze Drying Machine is a small vertical freeze drying equipment with capping and multi manifold bottle hanging functions. It has shelf heating and programmable functions, and can store hundreds of process formulas. Each formula contains 50 temperature control sections and can control the heating rate. There are 8 hanging bottles/freeze-drying bottles/eggplant shaped bottles as standard, which can freeze dry 8 different materials at the same time. The freeze-drying hood is equipped with 8 glue valves, each of which can hang a freeze-drying bottle. The vacuum state in the freeze-drying bottle can be controlled by controlling the switch of the glue valve. So after the freeze-drying bottle is rotated and frozen, it is directly hung on the glue valve, and the switch of the glue valve is opened to vacuum the sample in the freeze-drying bottle. 8 hanging bottles can be removed and hung at any time, improving the efficiency of freeze-drying. The starting temperature of the vacuum pump can be preset. When it is lower than the set temperature, the vacuum pump can be started effectively to prevent a large amount of water vapor from entering the pump; Extend the service life of vacuum pumps. The intelligent data recording system automatically saves freeze-drying data, continuously records real-time data to generate tables, and can be viewed in the form of real-time curves and historical curves, making the entire freeze-drying process clear and concise.

The capping type freeze dryer is mainly used for freeze-drying liquid in penicillin bottles. Firstly, the liquid is filled into the penicillin bottle, and the rubber stopper of the penicillin bottle is covered (moisture sublimates through the gap of the rubber stopper and condenses into frost in the cold trap). It is then placed in the drying chamber of the freeze dryer and freeze-dried according to the preset freeze-drying process. After freeze-drying is completed, the rubber stopper is compressed into the penicillin bottle under vacuum using a plug pressing device to form a freeze-dried powder injection, which is equivalent to vacuum packaging and can avoid secondary pollution caused by contact with air.

The main applications of LGJ-18S (electric heating) multi manifold cover type freeze dryer are:

Effectively suppressing the biological, chemical, or physical changes of thermosensitive substances, and effectively preserving the active substances in the raw materials, as well as maintaining the color of the raw materials.

Combining the characteristics of the pressure cover type and the common type of multi manifold.

Suitable for freeze-drying of bulk (liquid, paste, solid) conventional substances;

Suitable for drying penicillin bottled materials. When preparing for freeze-drying, divide the materials into penicillin bottles as needed, cover the bottle cap with a floating cap, and perform freeze-drying. After drying, operate the capping device to press the bottle cap tightly, which can avoid secondary pollution and re adsorption of moisture, and is easy to store for a long time;

Install a flask outside the drying chamber and dry the material frozen on the inner wall of the flask. At this time, the flask is connected to the manifold outside the drying oven as a container. The material in the flask is heated at room temperature and can be removed or added as needed through a multi manifold switch device without stopping the machine.
