Freeze Dryer
LABORATORY & INDUSTRIAL FREEZE DRYER (LYOPHILIZER)
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.
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
The main steps of freeze-drying
| Procedure | Time and purpose |
| 1, Product cleaning | 10min, remove |
| 2, Product peeling | 60min, remove the peel of some fruits |
| 3, Product dicing/slicing | 30min cut the product into small size, <10mm |
| 4, Product loading | 2min, loading cut product into trays |
| 5, Product freezing | 3h, get the product completely frozen in the shortest time |
| 6, Vapor condenser freezing | 30min, to catch vapor from sublimation |
| 7, Vacuum chamber | 30min, to have an extremely low pressure |
| 8, Heating product | 10-15h, to speed up the sublimation |
| 9, Unloading | 2min, unload the finished product |
| 10, Defrosting | 0.5-1h, defrost for next batch of production |
| 11, Packing | 30min, packing product avoid regaining moisture |
(for reference only, the time will be different as the difference of material)

FREEZE DRYER FOR LABORATORY, FOOD & PHARMACEUTICAL 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.
