Lyophilizer freeze dryer8/17/2023 ![]() Yatherm Scientific’s Freeze Dryer is ideal for meeting freeze drying requirements in research and development laboratories. 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. 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. As well as blood derivatives, cells, vaccines, viruses, serums, algae, and others.Īmong the advantages of this method are, for example, accurate dosage, low enzymatic activity, easy reconstitution, the possibility of sterile manufacture. As well as in the research and pharmaceutical industries, it stands out for allowing the preservation of enzymes, yeasts, and other microorganisms. 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. In the food industry, this method stands out for preserving the nutritional quality of food. The Nutrient Content of Fresh Strawberry and FD StrawberryįREEZE DRYER FOR LABORATORY, FOOD & PHARMACEUTICAL INDUSTRY: Strawberry freeze-dried with a heating temperature of 40☌, vacuum pressure <50Pa. The Nutrient Content of Fresh Fruits and Freeze-Dried Fruits Natural Pigment Extract from fruits & vegetable.Documents Recovery – Like Titanic ship Sink Documents PreservationįREEZE DRYER IDEAL FOR THE FOOD INDUSTRY:.Food Laboratory – Coffee, eggs, Fish, Fruit, and Juices.(for reference only, the time will be different as the difference of material) The main steps of freeze-drying Procedureģ0min cut the product into small size, <10mmģh, get the product completely frozen in the shortest timeĠ.5-1h, defrost for next batch of productionģ0min, packing product avoid regaining moisture 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 Right after the association of low temperature and pressure, it allows the solvent to be removed by sublimation. In principle, to start lyophilization, the sample must be completely frozen. It also increases the shelf life of products, which can be stored at room temperature for years. In addition, it preserves the samples by inhibiting enzymatic and oxidative reactions, which normally happen in the presence of water. Thus, as it works at low temperatures, it is also ideal for thermo-sensitive samples, such as enzymes. So it can be easily restored when hydrated. 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. 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. For the process to take place, the frozen product is dried under vacuum, without thawing. 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. Real time display curve for freeze-drying and temperature.The Freeze Dryer (Lyophilizer) is a device that allows the drying of materials without the need to heat them. Optional configuration of the inflation valve, which can be filled with dry inert gas.The drying chamber adopts a high light transmissive colorless transparent plexiglass door, which can clearly observe the change process of the material during the operation.The square tray is not easy to be deformed, easy to operate and easy to clean.Touch screen, you can set the power-on password to display the drying curve.30 sections can be set, the freeze dryer can modify the program parameters during the running process, and record the vacuum drying curve and data online.Temperature adjustable, controllable production process.The process consists of three separate, unique, and interdependent processes freezing, primary drying (sublimation), and secondary drying (desorption). Lyophilization or freeze drying is a process in which water is removed from a product after it is frozen and placed under a vacuum, allowing the ice to change directly from solid to vapor without passing through a liquid phase.
