Vacuum Transfer

Our Uni-Vac range of vacuum conveyors has been carefully designed and improved through our 20 years of experience with conveying. With transfer rates up to 4,000 kgs/hr, the Uni-Vac has been specifically designed with the needs of the end-user in mind.

The conveyor benefits from an ‘easy-clean’ design, which allows the system to be easily dismantled for cleaning without the need for tooling. In line with this, the conveyor boasts a ‘crevice-free’ design, which makes a thorough clean easier.

This not only improves hygiene, but also decreases operational downtime by enabling faster cleaning turnarounds. Furthermore all units are constructed from either 304 or 316 stainless steel to suit your process.

Hanningfield’s knowledge in the application and manufacture of lift systems also enable us to provide tailored designs, whereby the vacuum system can be hoist mounted for increased flexibility. We can also offer static or mobile versions dependent upon your needs.

Importantly, we are also able to remotely locate controls away from the vacuum conveyor itself. Not only does this comply with GMP, but also offers a hygiene based advantage, because the unit becomes easier to maintain and clean.

Our knowledge also helps us to solve problems and improve processes. For example, our experience with vacuum conveying and size reduction makes us experts at directly conveying into a cone mill; often known as ‘in-line cone milling’. This can significantly improve both the productivity and hygiene of a process. Our cross-discipline expertise makes us unique in our ability to understand and solve customer problems.

With a wealth of knowledge, Hanningfield are proud to be an expert in the design, manufacture and maintenance of vacuum transfer solutions. We have manufactured vacuum conveying systems for many companies around the world, and our experience and understanding of vacuum conveying make us confident we could help to solve your problem too.
