Introduction to Bell Jar Freeze Dryer
A bell jar freeze dryer is a type of freeze - drying equipment widely used in laboratories, research institutions, and some small - scale production facilities. Freeze - drying, also known as lyophilization, is a process that removes water from a frozen product by sublimation. In a bell jar freeze dryer, the product is placed inside a bell - shaped glass or plastic chamber. The chamber is connected to a vacuum pump and a condenser. First, the product is frozen, and then the vacuum is applied to lower the pressure inside the chamber. The frozen water in the product sublimates directly from the solid phase to the vapor phase and is then captured by the condenser, leaving behind a dry product. This process helps to preserve the structure, biological activity, and chemical composition of the product, making it suitable for applications such as food preservation, pharmaceutical production, and biological sample storage.
