Bevzduchování

Bevzduchování is a term that refers to the process of removing air or gases from a liquid. This is often done to improve the quality or properties of the liquid for specific applications. For example, in the food and beverage industry, deaeration can be used to prevent oxidation, extend shelf life, and improve the clarity of products like juices and wines. In the manufacturing of plastics and polymers, bevzduchování of resins is crucial to eliminate trapped air bubbles that can compromise the structural integrity of the final product.

Various methods are employed for bevzduchování. Vacuum deaeration involves subjecting the liquid to a vacuum, which lowers the boiling point of dissolved gases and allows them to escape. Mechanical methods include agitation, ultrasonic treatment, and centrifugal separation, all designed to dislodge and remove air bubbles. Thermal deaeration uses heat to reduce the solubility of gases in the liquid, facilitating their removal. The choice of method depends on factors such as the type of liquid, the volume to be processed, and the desired level of gas removal. Improperly deaerated liquids can lead to issues like cavitation in pumps, reduced efficiency in heat exchangers, and defects in manufactured goods.
