GEA markets three different types of UHT Plant - depending on the product to be treated, the product quality and efficiency:
These product treatment plant work according to the indirect heating principle. Their great benefit: Using this method, the UHT Plant Type I provides very high production safety. This process technology has proved successful for many years. The UHT Plant have optimized flow conditions which produce good product quality and high efficiency with a heat recovery of up to 90%.
Similar to the indirect UHT Plant Type I, the UHT Plant Type P is widely based on identical process technology.
The difference is that the tubular heat exchanger type P is used here – indirect heat transfer between the product to be heated and that to be cooled is not applied. The advantage is that this plant type achieves an even higher efficiency and improved product quality without the need to expand the heat exchange surface.
The direct heating method used in these UHT Plant offers the advantage of very high product quality. The integral steam injector and a flash cooler provide very short dwelling times in the temperature intensive zones.
