DUSTING
DOWN FOR YORKSHIRE TEABAGS
Taylors of Harrogate is one of the few remaining family tea
and coffee merchants and has been blending quality teas since
1886. Today, the company is best known for its Yorkshire Tea
blends.
As part of an ongoing programme of investment in processing
facilities at its 13 acre Harrogate site, Taylors has recently
installed a state-of-the-art dust extraction plant to deal
with airborne tea dust particles generated in its main line
tea packing area.
Specialist dust extraction company, Dust Control Systems Ltd
of Dewsbury, West Yorkshire, devised a turnkey scheme to replace
the old extraction plant with a more efficient system capable
of meeting current and future dust control requirements in
the Yorkshire Tea Hall.
The new system draws dust directly from
teabag filling stations and transports it via special ‘smooth bore’ galvanised
ducting for filtration by a dust collector housed in the roof
space above the tea hall.
The system comprises two ATEX approved ‘Downflo’ units
designed to handle air volumes of 20,400 cubic metres per hour,
providing enough capacity for current and future needs.
 The highly efficient Downflo dust collectors are fitted with
Fibra-WebTM filter cartridges that employ ‘Nanofiber’ filter
media capable of capturing dust of less than one micron in
size.
To limit the problems of noise and vibration
experienced with the previous plant, DCS installed anti-vibration
mountings between the plant’s structure and the building’s
steelwork. As a further soundproofing measure, the two 30kW
fansets were housed inside acoustic enclosures.
To avoid any disruption to production, DCS were required to
remove the old dust plant and install the new system over a
weekend. Large sections of the roof were removed to enable
the old equipment to be lifted out by crane and the new units
to be lowered into place.
Richard Martin, Project Engineer at Taylors
says, “It
was a very short time window in which to complete the installation
but everything went according to plan. The net result is that
we have a much quieter and more efficient system”.
