Greencore Chilled Sauces and Soups has invested in cooking and filling equipment from TLV Euro Engineering to increase production capacity and output at its Bristol site.

Greencore produces a range of own-branded cooking sauces and fresh soups for supermarket customers such as Asda, Co-op and Sainsbury’s.

More recently, the focus of the Greencore engineering team has been to increase the efficiency of the 10 cooking vessels at the site.

Spencer Wills, engineering manager at Greencore, said: ‘When the vessels were first installed they were fitted with standard TLV pilot valves, which, from a cold start, provided 1.5 bar of steam pressure in the jacket for the initial stages of cook.

‘However, we realised that in order to increase the productivity of the process we needed to increase the efficiency of the heat transfer, and TLV suggested fitting its CV-COS electro-pneumatic pressure-reducing valve, which combines a convenient control function with a pressure-reducing valve, separator and steam trap in one compact unit.’
The new valve, which is designed for process applications requiring automatic control of the pressure, temperature and the flow rate of steam, maintains a constant pressure in the jacket from start-up.

Besides improving heat transfer – and therefore efficiency and productivity – the CV-COS is also said to provide Greencore with the ability to easily change pressure in order to cook different sauces.

In addition, having an integral separator and steam trap means that the CV-COS provides consistently good steam quality at point-of-use, which also contributes to the efficiency of the production process.

Wills said the CV-COS installation was scheduled for the weekend to avoid process downtime, but when the unit itself arrived it had been damaged in transit.

He added: ‘It wasn’t TLV’s fault, but it delivered a replacement on the Saturday morning so that we didn’t have to interrupt Monday’s production.’

TLV was founded about 50 years ago in Japan and is now a recognised global leader in steam engineering and still family owned. From its UK headquarters in Cheltenham, the company offers a wide range of steam engineering products supported by services such as consulting, site inspections and seminar training.

TLV (the name derives from ‘Trouble Less Valve’) has always strived to manufacture innovative, high-quality, long-lasting steam engineering products and systems and one of its early successes — the A3 steam trap — was awarded no less than seven patents. This steam-heating, condensate-cooling, double-jacketed, thermodynamic steam trap is unaffected by ambient conditions and offers an incredible 10 times the durability of previous products.

TLV now designs and manufactures a wide range of products and systems such as the award-winning CV-COS, an electro-pneumatic pressure-reducing valve with a convenient control function; and the Vacuumizer, a vacuum pressure steam heating and cooling system.

TLV has also revolutionised fluid control technology with the launch of its patented ‘Free Float’ steam traps, which, with only one moving part, guarantee long life and reliability.
