The Freeze Dryer (Lyophilizer) is a device that allows the drying of materials without the need to heat them. The physical principle involved in lyophilization is sublimation, which is the direct passage from the solid to the gaseous state, without passing through the liquid state. For the process to take place, the frozen product is dried under vacuum, without thawing.
Working principle:
Lyophilizer Freeze drying machine works on the principle of vacuum freeze drying process in which material moisture stays into the vacuum condition and directly sublimed into the gaseous state. This process is known as sublimation that maintains the original color, natural shape and Nutritional value with good rehydration and good taste. In todays era of science and technology popular freeze dried snack food processing equipment’s also sued in various biological freeze drying industries.

FREEZE-DRYING PROCESS EQUIPMENT :
How does the freeze-drying process work?
In general, lyophilization is a process that consists of removing water (and other solvents) from a sample, through the sublimation process, which is the transition from a solid to a gaseous state, without going through a liquid state.
This process allows preserving the organoleptic characteristics, such as color, brightness, light, odor, texture and flavor, as well as the original shape of the product. So it can be easily restored when hydrated. Thus, as it works at low temperatures, it is also ideal for thermo-sensitive samples, such as enzymes. In addition, it preserves the samples by inhibiting enzymatic and oxidative reactions, which normally happen in the presence of water. It also increases the shelf life of products, which can be stored at room temperature for years.
In principle, to start lyophilization, the sample must be completely frozen. Right after the association of low temperature and pressure, it allows the solvent to be removed by sublimation. As a result, a product with a porous structure is obtained, as well as, free of moisture that can easily be reconstituted by adding water.

FREEZE DRYER FOR LABORATORY, FOOD & FRUITS INDUSTRY:
In the food industry, this method stands out for preserving the nutritional quality of food. The so-called “astronaut food” is a light option (since up to 90% of water/solvents are removed from the product), nutritious, and which maintains the flavor and aroma of the product is natural. As well as in the research and pharmaceutical industries, it stands out for allowing the preservation of enzymes, yeasts, and other microorganisms. As well as blood derivatives, cells, vaccines, viruses, serums, algae, and others.
Among the advantages of this method are, for example, accurate dosage, low enzymatic activity, easy reconstitution, the possibility of sterile manufacture. As well as the most recent applications are: the preservation of flowers and animals, documents and books old or recovered from floods, taxidermy, bone banks, and tissues for implantation. Freeze dryer for removing water or organic solvents from a vacuum solution and allowing the water frozen in the material to pass directly from the solid to the gas phase without going through the liquid phase.

How to Select a Right Freeze Dryer?
There are four to five types of freeze dryers are available in the market and each freeze dryer has different use.
- Pharmaceutical Freeze dryer
- Food Freeze dryer
- Lab Freeze dryer
- Lab freeze dryer Top Pressing
- Home / Kitchen Freeze dryer
- Pilot Freeze dryer
No pharma freeze dryer should be used to process food items. Pharma freeze dryers are configured with SS 316 construction, High quality cooling unit with environment friendly compressor & 7 inches touch panel PLC. Complete series of documents that meets the requirement of GMP & FDA. Pharmaceutical freeze dryers works on lower refrigeration temperature (-80 degree Celsius) & lowest vacuum pressure so we design the pharma freeze dryer with dual cascade system compressor and vacuum pump. These types of freeze dryer has high energy consumption which makes it expensive where Food freeze dryer works on -45 degree works on single compressor and single vacuum pump.
No home or kitchen freeze dryer to lyophilize freeze dried food as low price attract customers but configuration is very inferior. These types of freeze dryer works without independent vapour condenser that results water in food could not be removed timely. Vapours are suctioned by vacuum pump and it creates frequent change in vacuum oil & increases the time of drying.
Lab freeze dryer has many models like Top pressing chamber, Flask holding freeze dryers with manifolds and benchtop freeze dryer. Lab Freeze dryers are too small for freeze drying food products. All the Lab freeze dryer models doesn’t fulfil the basic needs of food freeze drying as it needs large surface area , lesser time and low power consumption. Choose your freeze dryer carefully, as different types of freeze dryer has different uses.
YATHERM® Scientific offers different types of freeze dryers, we have different shapes of freeze dryers too. We have rectangular and round shape freeze dryers in all available sizes. Choose your freeze dryer according to your space and requirement.
