The Steps of Using a Freeze Dryer to Lyophilize a Product Usually, you can dry most products to approximately 1 to 5% residual moisture. When the freeze-drying process is over, you will break the vacuum using an inert gas you should consider doing this before your product becomes sealed. Once that is done, the freeze-dried product will retain a structure that is porous. This is achieved through raising the temperature higher than the previous phase the sublimation stage, the bonds will then be broken between the product and the water molecule. During this phase, you will be getting rid of an ionically-bound water molecule. The final phase in the freeze-drying lyophilizer process is the secondary drying phase or the absorption phase. The secondary drying phase or the absorption phase When using excess heat, the structure of your product can be damaged easily. You should note that the primary drying phase is a relatively slow process however, it is very effective. Approximately 95% of the water in your product will be removed during the sublimation process. In addition to that, the condenser provides protection to the vacuum pump from coming into contact with water vapor. A cold condenser offers a surface where the water vapor will adhere and then solidify. Furthermore, the vacuum environment tends to speed up the sublimation process. The second phase in freeze-drying lyophilizer is sublimation or the primary drying phase in this phase, the pressure is lowered as heat is added to the product forcing the frozen water to be sublime rather than melting. The primary drying phase or the sublimation stage This is because this process involves a much faster freezing process, and it raises the temperature of the product allowing the crystals to grow. On the other hand, when working with materials that precipitate, it will be for you to use annealing. In order for one to prevent this from occurring, you should consider doing the freezing process rapidly. Nevertheless, when working with biological materials, using large ice crystals will affect the cell wall forcing them to break, resulting in a less than ideal freezing result. In addition to that, you will be able to preserve the physical form of your product.įreeze drying is relatively easy to accomplish when using large ice crystals that are often produced by annealing or slow freezing. The sublimation process will only occur when the product is chilled triple times its freezing point this will help skip the melting stage. You might consider freezing a product in a freezer, shell freezer (chilled bath), as well as in your freezer dryer’s shelf. There are numerous methods you can use when freezing a product. Continue reading this article and know more information about WKIE LAB freeze dryer lyophilizer. So, the freeze dryer lyophilizer is important equipment in our research and productions. When a product is properly freeze-dried, you will be able to reduce the drying process by approximately 30%. The freeze dryer lyophilizer occurs in three stages, with the freezing stage being the first and most critical. Usually, this process works by freezing a product and then reducing pressure and adding more heat to allow the frozen water in the product to sublimate without turning into a liquid state. You can use freeze dryer lyophilizer to extend the shelf-life of perishable products or make the material more convenient for transportation by removing water in the product. ![]() In most cases, freeze dryer lyophilizer applications include food processing such as coffee, biological processes such as yeasts and bacteria, biochemical processes such as surgical transplant and preservation processes. Under these conditions, the product’s original shape will be maintained while the rehydrated products develop excellent quality. It tends to produce high-quality products since it operates using extremely low temperatures. Freeze dryer lyophilizer is a machine that dehydrates your products.
