Freeze drying is a method of preserving a substance by pre freezing it into a solid state and then sublimating the moisture from the solid state to a gaseous state under vacuum, in order to remove the moisture and preserve the substance. Widely used in fields such as biopharmaceuticals, food, and materials.

The items obtained by this drying method have basically unchanged chemical and biological characteristics, and are easy to store for a long time. After adding water, they can return to their original form before freeze-drying and maintain their original biochemical characteristics. It is a drying method.

freeze dryerIt mainly consists of a refrigeration system, a condensing system, a water trap, a heater, a vacuum system, and a control system. Reasonable setting of various parameters can make the operation of the freeze dryer both economical and efficient.

We know that the freeze-drying process varies greatly depending on the materials used, which requires modern freeze-drying machines to have the function of setting freeze-drying curves.Shuangjia freeze dryerBy adopting an advanced control system, not only can the temperature be controlled, but also the vacuum degree can be controlled in real time.

We know that an important step in the freeze-drying process is to find the eutectic point temperature of the material in order to obtain products with more economical methods and better performance. The Shuangjia pilot freeze dryer is equipped with an automatic search function for the eutectic point of materials, helping users find the freezing point and eutectic point of materials.
