Sterilization refers to the complete annihilation of microorganisms and bacteria. It is used primarily on food processing equipment as well as on medical or microbiology equipment. Hot-air sterilization is used on objects made from glass, metal, or porcelain, and takes at least 30 minutes at a temperature of 180°C. For the purpose of preserving it, food is sterilized at temperatures above 100°C. However, it often loses its nutritional value and flavor during this process.

Pasteurization is mainly used on food with a view to increasing its shelf life. It takes place at temperatures below 100°C and is used to kill microorganisms. Afterwards, the food is not completely free of germs and so must usually be kept refrigerated.

In both cases, hot air is very good at achieving the required temperatures for the relevant period of time. The precisely controlled air heaters and hot-air blowers from Leister are perfect for ensuring safe and reliable process control during sterilization and pasteurization. Thanks to their ease of integration, they are also ideal for installation in sterilization/pasteurization systems and equipment.
