During the direct high-heating, steam is injected into the product by means of a DSI unit (DSI = direct steam injector). In this way, the product is suddenly heated and flashed against a low pressure after a very short holding period and in this way it is cooled again just as quickly.
This sterilization process shows significant advantages compared to an indirect high-heating by means of heat exchangers. In case of indirect high heating the holding time at high temperatures is much longer.The short retension time and the possibility to treat high viscous products are the main advantages of this technology.
Whether it’s a fad or the future, 100% vial traceability is becoming an increasingly important consideration in the pharmaceutical freeze drying industry. Keeping a close eye on developments is GEA. We’re investigating possible solutions and, what’s more, we have the experience, expertise and know-how to implement them.
At GEA, our commitment to engineering for a better world fuels our pursuit of innovative solutions that enhance patient care and safety. One of our most promising ventures in recent years is aseptic spray drying – a technology that promises to revolutionize pharmaceutical manufacturing.
