Installing a Cream Yeast system in Dunstable

What is at the heart of a good bakery product?

What is at the heart of a good bakery product? Is it the careful choice of ingredients, the attention to detail in designing a product which resonates with the public taste or the consistency of the production model? Well actually it is all three but no matter how carefully the ingredients are selected or how much effort is put into design and development; unless the production model is consistent the resultant product will vary in the extreme.

At the heart of bread production sits the cream yeast system; ensuring that the right mix at the optimum temperature is delivered consistently. Any failure in the cream yeast system will at best halt production, at worst lead to a product which is merely fit for waste recycling so the system design has to be efficient, robust and have built-in safeguards.

When one of the world’s largest bakery producers, ARYZTA decided to expand production in its Dunstable plant it called on the services of Beswick Refrigeration Services to install a “state of the art” Automatic Cream Yeast System, complete with a process chilled water system and mixer jacket cooling to the high speed horizontal mixers.

BRS sits at the forefront of cream yeast installation technology; drawing on a wealth of experience allied to the awareness of technological developments to design robust systems which meet the exacting demands of today’s mass-production facilities. Incorporating a twin tank system within the design enabled ARYZTA to maintain continuous production with one of the 26,000L tanks being cleaned or refilled whilst the other one is in use.

Chilled water is a prime ingredient of the liquid ingredients package and BRS installed a reliable system that supplies a constant +2degC chilled water supply to the mixers. To ensure a consistent rise, dough temperature is also critical and BRS commissioned a glycol cooling system to ensure that dough temperature was maintained within set parameters.

ARYZTA makes” speciality bread and bakery products, including pancakes, crumpets, tortillas and naans, for all the major grocery retailers in the UK and for some of the world’s biggest quick serve restaurants.” Maintaining consistent production is therefore key to its success and the Automatic Cream Yeast, process chilled water and mixer jacket cooling systems which BRS commissioned and installed will help ARYZTA to fulfil its bakery production schedule.
