GEA CONTA dual block valve technology

GEA has introduced its patented CONTA dual block valve technology for food and dairy spray dryers. The unit has an improved sanitary design which can help to reduce microbiological risks and improve product safety.

The value receives feed from the feed supply system and distributes it to multiple atomiser nozzles, which then spray the feed into the drying chamber. Compared to traditional designs, the new design is claimed to reduce the areas where feed can accumulate by up to 96%, allowing for more efficient cleaning in place (CIP) and reducing microbiological risks.

Each valve weighs approximately half the weight of traditional systems, making it easier and safer to handle. The design eliminates the use of external welded manifolds, allowing manual inspection and maintenance with simple tools. This simplified inspection and maintenance supports 24/7 operation and can reduce plant downtime.

The standardised unit can be easily configured for both new and existing spray drying systems. Retrofitting to existing spray dryers is straightforward, often requiring only minor programming changes.
