Busch Dolphin ring vacuum pumps have been supplied to a food supplier which produces savoury products used in ready meals such as ratatouille.

Two Busch Dolphin LX liquid ring vacuum pumps have been supplied to 2 Sisters’ Cavaghan & Gray manufacturing facility in Carlisle, which produces savoury products used in ready meals such as ratatouille, white wine sauce and other savoury fillings. These products are supplied to 2 Sisters’ customer base which includes some of the UK’s leading high street food retailers and food service providers.

The two Dolphins are close-coupled and used within the production process where vacuum quickens the cooking time and enables the products to be perfectly cooked at a lower temperature, which in turn means less energy is used. Liquid ring vacuum pumps are particularly appropriate for applications such as this where there are large amounts of water and steam involved in the process as the performance of the pump is unaffected and any moisture is simply absorbed and discharged.

Mark Sumnall, UK sales director for Busch, said: “We work with a number of 2 Sisters’ sites across the country and it is great that our products are being successfully used at the Cavaghan & Gray site for the manufacture of some of the UK’s top quality ready meals.

“Our Dolphin liquid ring vacuum pumps are particularly appropriate for cooking applications such as this as they can easily cope with the steam and water generated from the process while at the same time delivering excellent performance and energy savings for our customer.”

Minimizing energy costs

Matt Soden, category buyer for engineering for 2 Sisters Food Group, said: “To create a quality product we need quality equipment that can cope with a high moisture production environment, while also keeping our energy usage and costs to a minimum. Installing the Busch Dolphins means we are able to deliver first class savoury products that are cooked to the best possible standard while also meeting our energy use reduction requirements.”

With its proven compression principle meaning it is suitable for a wide variety of industrial applications requiring a vacuum pump, in addition to food processing Dolphin is used in the chemical and pharmaceutical sectors, plus timber treatment and plastics. In particular, critical applications such as evacuating humid gases or vapours are achievable without difficulty.

Dolphin’s liquid ring technology works with just one moving part, the impeller shaft assembly, which is mounted eccentrically relative to the casing. The liquid ring is formed by the service liquid, which is normally water, rotating concentrically.

Process gas enters via the suction port and travels between the impeller blades and is compressed prior to ejection through the discharge port with a quantity of service liquid.

Particularly suitable for the handling of wet/corrosive process streams, the company says other benefits of the product are robust construction, minimum heat emission and low maintenance requirements.
