Tetra Pak has unveiled a new industrial mixer designed to eliminate foaming and minimise product loss in liquid protein processing.

The Tetra Pak Industrial Protein Mixer employs a sophisticated multi-step process that reduces air ingress and uses advanced automation to optimise the mixing procedure, resulting in a foam-free operation.

Foaming during liquid protein mixing is estimated to cost manufacturers around €276,400 annually, according to Tetra Pak, as it leads to product loss and requires additional cleaning and maintenance.

Fiona Liebehenz, vice president of key components, plant solutions and channel management at Tetra Pak, said: "This progressive new Tetra Pak Industrial Product Mixer was the result of a customer approaching us with serious foaming issues at their factory, disrupting production and compromising product quality".

The new mixer not only eliminates the need for defoaming additives like silicon oil, but also helps reduce nutrient oxidation and extend shelf life, the company said.

With the global market for active nutrition products expected to reach €80 billion by 2030, the Tetra Pak mixer is poised to support food and beverage manufacturers as they look to capitalise on the growing demand for protein-enriched products.

Capable of handling a broad range of protein sources, from whey to plant-based and fermentation-derived, the mixer can process outputs ranging from small trial batches to large-scale production of up to 50,000 litres per hour.

"This is just one example of our commitment to taking care of the immediate needs of our customers, not only solving the problem at hand but creating a solution to improve future productivity and profitability," Liebehenz added.

The launch of the Tetra Pak Industrial Protein Mixer comes as consumer interest in health and wellness continues to rise, with 70% of consumers confirming that health has become more important to them in recent years.
