No (dust) cloud to have a Silvery lining!

Dustcheck Ltd reports a very successful dust control system at Silvery Tweed Cereals Ltd (Silvery Tweed) which has been in operation for well over a year now and with whose performance the customer is delighted. Following the signing of a strategic alliance to produce certain bread mixes for Rank Hovis McDougal, Silvery Tweed of Berwick-upon-Tweed sought contractors and suppliers to provide a new Automated Bakery Mix Blending System. They currently produce around 26,000 tonnes of product a year from a variety of dusty organic materials including some enzymes which are a particular health hazard. Therefore, from the outset, environmental dust control and compliance with the ATEX regulations were critical considerations for the new 7m [pounds sterling] production facility.

The Silvery Tweed dust collection system employs a wing type reverse jet cleaning system. The filter housing is cleaned once a week and it only takes 30 minutes. Despite being in operation for over a year now, none of the cartridge elements have yet needed to he replaced.

Dustcheck has included extraction points at every FIBC Discharger, sack tip station, weighing station, x-ray machine, day bin, receiving bin and packing line in the system. An in-line filter, with quick change cartridge, is fitted directly above the mixer so that product displaced during the filling cycle is returned to the mix by the reverse jet cleaning system. Silvery Tweed has a dedicated quick-change mixer cartridge for each different mix to prevent cross-contamination.

From the start, Dustcheck's design engineers realised that installation of the system at Silvery Tweed would coincide with the ATEX Directive coming into force for all new installations. They carried out a full risk assessment of the application and, as a result, the system includes antistatic filter cartridges, anti-spark fans with motors outside of the air stream and full explosion relief. The dust collector has explosion relief panels but, in addition, there is a relief panel in the main extract ductwork to prevent flame propagation back along the duct in the event of an overpressure situation in the filter housing.

All of the ductwork is of galvanised steel and is 'clipped' together for easy cleaning.
