Spx Flow has launched a new technology, SteamRecycle, aimed at improving sustainability in ultra-high temperature (UHT) processing for the dairy, nutritional and plant-based beverage sectors.

This system claims to recover and reuse 100% of the steam generated during the infusion UHT process, potentially reducing carbon dioxide emissions and water usage significantly.

The SteamRecycle system enables producers to eliminate the need for fresh steam after start-up, a change that could lead to a reduction of up to 1,000 tons of CO2 emissions annually, based on an operational model of 6,000 hours per year.

Additionally, the technology may decrease water recirculation needs by as much as 33 cubic metres per hour compared to conventional infusion UHT systems.

Operational mechanism and benefits:

Closed-loop system: The technology utilises mechanical vapor compressors to recover low-pressure steam, converting it into high-pressure steam for reuse. This closed-loop approach minimises the reliance on fresh steam, thereby lowering energy consumption and emissions throughout the production process.

Cost implications: The integration of SteamRecycle is projected to improve operational efficiency and reduce costs associated with steam and energy use. Spx Flow estimates a payback period of approximately four to five years, contingent on local energy prices.

Product quality maintenance: The infusion UHT process is known for its ability to deliver high-quality products with extended run times. The SteamRecycle system aims to preserve these quality standards while reducing energy demands.

Gerard Lang, VP of process solutions and strategy at Spx Flow, noted the increasing pressure on food and beverage manufacturers to balance product quality with sustainability.

“By recycling steam for greater cost efficiency, producers can continue creating high-quality products and use fewer resources simultaneously,” Lang commented, highlighting the need for solutions that align operational goals with sustainability efforts.
