KD-18N series freeze dryer working principle
Vacuum freeze drying technology, also known as freeze-drying technology.It refers to the process in which the solid material is directly sublimated into a gaseous state for drying under vacuum conditions. During lyophilization, the solvent is sublimed directly from the solid state to a gaseous state.When the solid solvent is sublimed, the pores are left in the dry remaining material, so the original chemical structure and morphology of the solute are not destroyed.The freeze-dried article is prone to long-term storage, and the biologically active material retains its biological function prior to lyophilization after reconstitution.Therefore, freeze-drying technology is considered to be the least safe and effective method of drying the properties of the material being dried.

Q: How long does it take for the freeze dryer to freeze dry?
A: The lyophilization process of freeze-drying machine mainly includes two parts: low temperature pre-freezing and vacuum freeze-drying. The drying process is actually the process of water state change and movement. This change and movement occur under low temperature and low pressure, so it is called freeze-drying (also called Freeze-dried, English abbreviation FD).
Then, how long does it take for the freeze dryer to freeze and dry, and how long does it usually freeze? The whole process of vacuum freeze-drying of the freeze dryer is carried out under vacuum low temperature and low pressure environment, and the heat sensitive component of the freeze-dried product can be effectively retained. Therefore, it takes about 24 hours for the freeze-drying to be once, and the specific freeze-dried products are also different. Freeze-dried fruits and vegetables are generally crisp for more than ten hours. If it is a biological product with low crystallization point, it usually takes 30 hours.
