Sterilization of concentrated food products using direct steam
Achieve rapid and efficient sterilization with direct steam injection, ensuring the quality and safety of concentrated food products through minimal retention time and effective flash cooling.
Sterilizes and Flash Cools Liquid Products
The Direct Steam Injector Sterilizer from GEA is designed to enhance the sterilization process for liquid products. By injecting steam directly into concentrated food, dairy, and pharmaceutical liquids, the unit rapidly heats and subsequently flash cools the product, ensuring minimal thermal degradation and optimal safety. Ideal for applications such as UHT milk, fruit juice concentrates, and fish protein hydrolysates, this technology enables precise control over sterilization without prolonged exposure to high temperatures. Capable of handling continuous, high-speed operations via direct steam injection, it integrates seamlessly with existing production lines. Constructed for durability, it offers high resistance to corrosive environments and can be customized with different material options to suit specific industrial needs. Compliance with industry standards ensures reliability across food, beverage, and pharmaceutical sectors. GEA supports its customers with engineering expertise for optimal configuration and seamless process integration.
