Continuous blending is widely used in the manufacture of all kinds of beverages, including still drinks, juices, nectars, enhanced water and even sensitive carbonated soft drink (CSD) products.
Seeking to improve their cost-effectiveness and sustainability, beverage producers are looking for smarter blending that saves time and money. In particular, they seek to get the highest possible yield on their ingredients and to reduce product losses. In more arid areas, saving water is important. They also want to ensure a consistent output – a blend with the required Brix level.
Producers face two major challenges: When blending begins, the mix contains excess water, which must either be discarded, taking with it some concentrate, or captured for re-use. Secondly, the greater the physical distance between blender and pasteurizer, the greater the potential product loss. The need to minimize this distance constrains plant layout options.
Product recovery systems have been available for some 20 years, but through continuous refinement, applying the company’s complete application knowhow and line design expertise, Tetra Pak’s latest blending equipment has been designed to address these challenges. It works like this:
This solution also eliminates plant layout constraints, since the pasteurizer and inline blender are integrated and can operate, essentially, as a single unit. This solution saves valuable space since its buffer tank also acts as a saver tank. By contrast, competing systems need three tanks; one each for buffer, water and mix phase.
