Tetra Pak’s new high shear mixer R370-1000D

Tetra Pak‘s next generation high shear inline mixer offers customers unparalleled ingredient mixing performance and lower operating costs. Featuring a radical new design that produces finer, more consistent and more stable emulsions, the new R370-1000D reduces the need for downstream homogenization, delivers a better quality end product and cuts energy bills. Monica Gimre, executive vice president, processing systems at Tetra Pak, said, “We developed this revolutionary new design in direct response to customer needs. A complete break with the status quo, our new mixer streamlines production steps, reduces investment needs, lowers costs and sets a new benchmark for the industry.”

Crucial to this innovative new mixer is the unique restructuring and integration of a built-in de-aerating system, a flexible powder introduction system and a newly designed mixing head. This allows the new machine to handle the highest viscosities for a recirculation mixer at up to 2,000 cP and break the size of the droplets to 1 micron (0.001 mm), significantly smaller than the industry average of 7 microns.

The output of a much finer, more consistent and more stable emulsion reduces the need for downstream homogenisation, a highly energy-intensive step in food processing. This means that it is now possible to eliminate the homogenisation step altogether in the production of certain types of ice creams, cutting energy consumption by up to 50% in the overall process.

The new mixer can also handle ingredients with up to 65% dry matter, the highest concentration for infant formula production. This cuts down the need for evaporation, another expensive step in food processing, slashing costs by up to 90%. The mixing machine produces at a capacity of up to 30,000 liters per hour and can be applied in the production of liquid dairy and beverages, ice cream and prepared food, as well as for most premixing needs in food manufacturing. Tetra Pak holds a number of patents and pending patents for the Tetra Pak High Shear Mixer R370-1000D.

The impact, resilience, and growth of responsible packaging in a wide region are daily chronicled by Packaging South Asia.

A multi-channel B2B publication and digital platform such as Packaging South Asia is always aware of the prospect of new beginnings and renewal. Its 16-year-old print monthly, based in New Delhi, India has demonstrated its commitment to progress and growth. The Indian and Asian packaging industries have shown resilience in the face of ongoing challenges over the past three years.

As we present our publishing plan for 2023, India’s real GDP growth for the financial year ending 31 March 2023 will reach 6.3%. Packaging industry growth has exceeded GDP growth even when allowing for inflation in the past three years.

The capacity for flexible film manufacturing in India increased by 33% over the past three years. With orders in place, we expect another 33% capacity addition from 2023 to 2025. Capacities in monocartons, corrugation, aseptic liquid packaging, and labels have grown similarly. The numbers are positive for most of the economies in the region – our platform increasingly reaches and influences these.

Even given the disruptions of supply chains, raw material prices, and the challenge of responsible and sustainable packaging, packaging in all its creative forms and purposes has significant headroom to grow in India and Asia. Our context and coverage engulf the entire packaging supply chain – from concept to shelf and further – to waste collection and recycling. We target brand owners, product managers, raw material suppliers, packaging designers and converters, and recyclers.
