KD-12ND freeze dryer

KD-12ND freeze dryer

Our freeze dryers are widely used in the pharmaceutical industry, laboratories and industries, adopting a dual-machine cascade refrigeration system, with mature technology, and the lowest temperature can reach -80°C.

KD-12ND has a heating function to speed up the drying process.


Experimental vacuum freeze dryers are widely used in the fields of medicine, pharmacy, biological research, chemical industry and food. Freeze-dried items are easy to store for a long time, and can be restored to the state before freeze-drying after adding water and maintain the original biochemical properties. Freeze dryer, suitable for laboratory use, can meet the requirements of routine freeze-drying in most laboratories.

1. Can the vacuum pump be stopped when the vacuum pump of the freeze dryer is working?

This kind of operation is feasible, but the prerequisite is that the vacuum of the vacuum pump is high enough. Otherwise it will increase the drying time.


2. What models of your freeze dryer have?

Freeze dryer 10N, Freeze dryer 10ND, Freeze dryer 12N, Freeze dryer 12ND, Freeze dryer 18N, Freeze dryer 18ND.


3. What is the function of the food freeze dryer?

The principle of the food freeze dryer is to freeze the moisture in the fresh food into a solid (ice) in a low temperature (about -40°C) environment, and then control the temperature in a vacuum environment to make the solid ice directly become gaseous and sublimate. , So as to achieve the purpose of drying. The entire freeze-drying process is carried out in a low temperature environment, so the freeze-dried food can maintain the original appearance, size, color and the most important nutrients.
