Noise levels reduced at spice blending plant
Vacuum and low pressure pump specia
list Busch (UK) has helped to reduce noise levels for specialist food manufacturer AB World Foods.
A key requirement for the company was to reduce noise levels from its existing vacuum pump equipment used in the spice blending plant at its facility in Leigh, UK, which predominantly manufactures Patak’s ready-to-use sauces as well as selected products from the Levi Roots and Blue Dragon ranges.
The engineering team called upon Busch engineers to help find a solution, and following a site visit and a full evaluation, three Busch Tyr rotary lobe blower pumps were selected and installed. Initially, one pump was trialled for a three-month period so that AB World Foods could properly assess the performance and results before adding the additional two Tyrs to the system.
Tony Marsh, site engineering manager at AB World Foods, explains, “Our main priority with this project was to reduce the noise levels within the plant to improve the environment for our employees. With our previous equipment and arrangement, the noise levels regularly ranged between 98-103dba and following the replacement with the Busch Tyrs, they have decreased to 83dba, therefore achieving a huge reduction in noise for us.
“In this case, cost was not necessarily the issue – rather, it was more important to us to significantly improve the noise levels as part of our drive to make our facility a more desirable place to work.”
Mark Sumnall, sales director for Busch (UK), notes, “This project is a perfect example of how the Busch team uses its expertise and innovation to work with our customers to find solutions to problems. Following all the site visits and evaluations, we trialled the first Tyr which quickly proved its paces and led to the installation of a further two pumps.
“The Tyr is a highly engineered, flexible and superior quality rotary lobe blower that offers some great benefits for the customer. As demonstrated with this application, it provides particularly quiet operation, but also offers ease of access and compact design with a footprint which is up to 30% smaller than equivalent products on the market.”
Developed to deliver energy efficient vacuum and over pressure generation, Busch says the Tyr range is setting a new benchmark in terms of performance and noise level reduction.
Other key benefits include the ability to work with variable speed control. A centrifugal ventilator provides a low, stable temperature within the casing to ensure optimum operation, whilst vacuum/pressure safety valves secure the pump against overload.
