Meet our newest innovation: the E2E SteamClosure

We developed the E²E SteamClosure together with the specialists of the Dutch company Solutherm. Flake production involves passing puree over a heated drum dryer, which evaporates the moisture to leave a thin potato sheet behind. This is subsequently ground up into potato flakes of the desired size. A lot of steam is released during the process and has to be extracted. All the steam is captured in pure form due to the ingenious design of the newly developed and patented Tummers E²E SteamClosure, which is fitted hermetically over the drum dryer.

Water extraction

Normally the steam would be extracted along with plenty of air, but here the steam is being fed into the E²E FlowCondenser and turned into water. This new concept produces water at 85 – 95 °C, which can be reused elsewhere in the production process for blanching, heating, cleaning or other purposes. This is a revolutionary process, as it is focused solely on moisture extracted from the potatoes and converted by the condenser into water which can be used somewhere else in the process.

Successful innovation

The E²E SteamClosure has been subjected to comprehensive testing in an existing production environment belonging to one of Tummers’ customers and the results far exceed expectations. R&D Engineer Dennis Rademakers explains: ‘Obviously you go into the testing with certain expectations, hoping that these will be met in the results. But now the tests have exceeded not only our expectations but our customer’s too, which is great.

One step closer to the factory of the future

Our E²E concept uses innovative solutions to convert emissions to energy, enabling customers to create a future-proof, sustainable and cost-efficient production process. Marking another step towards the emissions-free factory of the future.

Our Customers and the Planet benefit

Aside from making the drying process emissions-free, the E²E SteamClosure has plenty of other additional benefits which were picked up during the tests. The fact that the E²E SteamClosure is hermetically sealed means that the flakes are being dried in a controllable environment at a constant temperature and humidity, making the drying process more stable. What’s more, the hermetic seal also ensures that there’s no longer any air in the extractor, which means we can monitor the drying process perfectly because of the windows in the housing. In principle, the combination of the high, constant temperature and the sealed environment create a sterile space, boosting the hygiene of the production process. Once the extractor is switched off, it automatically drains nearly completely dry. The fact that no condensation is left in the extractor is beneficial in terms of hygiene and saves a lot of cleaning work.
