Industrial and laboratory Freeze Dryer (Lyophilizer)
Freeze drying is a process of removal of water content from the samples by freezing and vacuuming the samples at standard set temperature & vacuum. Lyophilization process includes two stages of drying in its complete set of working. First is known as primary drying and the second one is secondary drying.
Sublimation (primary drying) – Sublimation is a process of transition from solid samples to the gaseous evaporation. Freeze the solids, semi-solid & liquid samples first at -40 degrees or -80 degrees Celsius. Vacuuming at 760 mm Hg will evaporate the freeze samples moisture by a vacuum drying process.
Desorption (Secondary drying) – Secondary drying will release the water content from the top of the surface with the help of a vacuum pump. Desorption is the phenomenon of the release of substance through a surface which is the most important part of freeze drying.
The water content in the product first freeze into ice form and then convert into vapor takes the time of 6 hours to 72 hours. This time duration depends on the sample freezing point and time taken into vacuum drying. This process of lyophilization is used to preserve the samples for a long time and When it returns to its original state it doesn’t lose its biochemical properties. Lyophilization is a standard procedure followed by pharmaceutical companies for biological products that are sensitive to body fluids, hormones, blood products, vaccines & antibiotics.
