Recover. Recompress. Reuse.

With SteamClosure, Tummers took an important step towards recovering valuable energy from potato flake production. Previously featured in the Interpom Innovation Tour, SteamClosure captures residual heat from drum drying and makes it available for reuse.

Now, together with Callens (Stand XX), we are taking the next step. Mechanical Vapour Recompression captures energy from the process vapour, transfers it to a clean steam circuit and uses compressors to bring the steam back to the pressure and temperature required by the drum dryers.

The first pilot at Aviko Rixona is scheduled for the end of 2026, targeting a COP of 4 and an estimated reduction of 8,000 tonnes of CO₂ per year.

Together, SteamClosure and MVR bring potato flake production closer to a circular energy process: recovering, upgrading and reusing energy instead of letting it go to waste.

SteamClosure was the first step. MVR is the next.

Key benefits

• Builds on the proven energy recovery principle of SteamClosure
• Recovers and upgrades energy from the drum drying process
• Returns recovered energy to the drying process
• Expected COP of 4
• Significantly reduces natural gas demand
• Potential reduction of approximately 8,000 tonnes of CO₂ per year*
• Lower electrical grid demand compared with direct electric steam generation
• Takes potato flake production closer to a circular energy process

*Based on expected performance of the first pilot installation.
