Freeze Dryer
A lyophilizer is an essential instrument in the pharmaceutical and food industry, it is a very useful equipment when you want to conserve products, because it allows to remove moisture through cold drying.
The material to be lyophilized is introduced into the equipment, where there are very low temperatures, usually below - 40°C. With a vacuum pump, the pressure in the equipment is reduced. Having lowered the temperature the organic water or solvent freezes. Subsequently, when the pressure is lowered, the water that is in solid state is steamed into the process known as sublimation.
Types of Lyophilizers a Laboratory may need
Benchtop Laboratory Freeze Dryer
Parts of a lyophilizer
- Dry chamber or freeze-drying chamber: is the place where the substance or product to be lyophilized is placed. It can present different shapes with compartments where sublimation takes place, passing the water from solid to steam. The closure is airtight and is worked under vacuum.
- Condenser with cooling circuit: This device communicates with the dry chamber and condenses the steam that is generated in the sublimation. A coolant keeps it at a lower temperature than the dry chamber (-50 to -125 °C).
- Vacuum System: The vacuum is generated by an oil pump working on 10-2 mbar connected to a trap so that no vapors from the solvent will pass into it. The vacuum system first removes air from the dry chamber when starting the freeze-drying process, and then helps the sublimation.

Freezers are highly sophisticated equipment, and thanks to technological advances there is a great variety, which are perfectly adapted to the field of application in which they are used. We have freeze-driers that are used in the food industry, whether it's to make space food, military food or dehydrated food. As well as to make dairy products. There are also lyophilizers used in the pharmaceutical industry to conserve drugs and vaccines. As well as there are freeze dryers that are employed in the recovery of documents damaged by water.
Freezers can also be grouped by size into laboratory units, pilot units for process development and expansion, and larger production units. Likewise, freeze-driers can also be classified according to the type of product chamber:
- Lyophilizers in which the product is usually pre-frozen and in bottles,
- Freeze-driers with shelves where the product is placed on a tray or directly on a shelf.
- Freezers with units that combine with both drying options.
