Working together for the food industry

“As a central dessert kitchen, hygiene is our top priority. So we replaced our paper towel system with Dyson Airblade 9kJ and Airblade Wash+Dry hand dryers in every part of our kitchens from the entry to the product areas.”

Rachel Wong

Marketing Director of Green Week Catering

Better hygiene, no more waste, and a sustainable way of drying hands

Consumer safety is paramount in food production, and this requires a very high standard of hygiene especially in practices like handwashing. Dyson Airblade 9kJ and Airblade Wash+Dry hand dryers ensure that staff can dry their hands in HEPA filtered air in as little as 10 seconds without touching the dryers, and without any unhygienic and unsustainable paper waste.

The problem

As a central kitchen, Green Week has exceptionally high hygiene standards, and kitchen staff are required to wash and dry their hands in a very strict manner many times throughout the day.

Paper towels can lead to unsightly, unhygienic washrooms with overflowing bins. Constant re-stocking is also required and this leads to higher running costs. So Green Week were looking for a better, more efficient, ultra-hygienic and sustainable hand-drying solution.

Key technology

  • Sheets of air being forced through apertures of Dyson Airblade Wash+Dry

    Airblade™ technology

    Clean air from the HEPA filter is forced at 549km/h through apertures 0.55mm wide, scraping water from hands, quickly and hygienically.

  • The Dyson Airblade Wash+Dry tap with the motor exposed

    Dries hands at 549km/h with the Dyson digital motor V4

    The Dyson digital motor V4 uses digital pulse technology to spin at up to 81,000rpm – three times faster than a conventional motor. So it can draw up to 21 litres of air per second through the machine.

  • Close-up of the HEPA filter
