Sustainable Food Processing: How Better Equipment Design Can Reduce Water, Energy and Waste

For food processors, sustainability is increasingly about more than headline environmental targets. It is about looking closely at what happens every day on the production line – how much water is used, where energy is consumed, how much good product becomes waste and whether equipment is designed to use resources efficiently.

This is where intelligent equipment design can make a genuine difference.

Designing efficiency into the process

Turatti has spent more than 40 years developing equipment and processing lines for fruit, vegetables, salads and other fresh produce. Today, sustainability is an important part of its design philosophy, with attention to reducing water and energy consumption, controlling waste, and protecting the quantity and quality of edible product.

Importantly, these aren't simply sustainability principles applied after a machine has been designed. They can influence how the equipment itself operates.

Take washing as an example. Water is essential to many fresh produce processes, but simply using more water doesn't necessarily produce a better result.

Turatti's CAMEL continuous washing and treatment system reduces water consumption while significantly reducing the use of disinfection additives. The system fully immerses the product and provides precise control over treatment time, while its gentle handling suits fragile produce such as salads and prepared vegetables.

Elsewhere in the range, the Chios reception and sanitation tank incorporates filtration that allows washing water to be recycled within the system, helping to reduce both water and additive consumption.

Looking beyond water consumption

Energy presents another opportunity.

After washing, fresh produce frequently needs excess surface moisture removed before moving further through production. Turatti's Vortex and Vortex-H centrifugal dryers show how attention to engineering detail can improve efficiency at this stage.

Rather than simply concentrating on drying performance, Turatti uses inverter-controlled motor technology designed to reduce energy consumption and recover energy generated during braking.

The Vortex-H combines this with a direct-drive system and has been developed to achieve high drying performance while minimising damage to delicate products such as baby leaves.

It illustrates how seemingly small engineering decisions can become significant when a machine operates repeatedly, day after day.

Protecting another valuable resource – the product

Sustainability also means considering what happens to the food itself.

Poor handling, excessive mechanical action or an unsuitable process can damage otherwise saleable produce. For processors working with high volumes, even relatively small improvements in product preservation can therefore become important.

Turatti describes this approach as part of its Natural Innovation philosophy: reducing waste not only in water and energy consumption, but also in the by-products generated during processing, while preserving the quality and quantity of edible food.

Gentle washing, controlled treatment, effective drying and careful product handling can all contribute to getting more usable product through the line in the required condition.

Small efficiencies can make a big difference

Rarely does one piece of equipment suddenly make an entire food processing operation sustainable.

Instead, improvements come from examining each stage and asking better questions. Could water be filtered and reused? Could additives be reduced? Could energy be recovered? Could gentler handling reduce product damage? Could better control deliver the same result using fewer resources?

Applied across a busy production line, these details can add up.

As the UK and Ireland supplier of Turatti processing equipment, Wrightfield can help fresh produce processors explore the extensive Turatti range and identify technologies suited to their products, processes and production requirements.

Because more sustainable food processing starts with designing efficiency into the process.
