All bakery manufacturing units which handles flour and
grinded sugar must take preventive steps for sugar and flour dust . Flour and sugar are explosive material with following
factors increase the possibility of an explosion such as
- Combustible dust
- Dispersion
- An oxidiser (such as air)
- Confinement
- Ignition source
Flour in most of bakeries are now is done through bulk handling where wheat flour are stored in large silos . Conveying is
done through pneumatic conveyors its in these
pipelines that explosion might happens . Filters bags are also used in these bulk
handling of flour which are also explosion zone in bakery .Electrostatic
arrestors has to be installed on these areas to prevent explosion .
Similarly sugar grinding are done in
house for most of the bakery plants . Sugar when
grinded becomes charged and with given atmosphere can result in explosion . Electrostatic
arrestors and earth should be provided to
sugar grinder as well as the filter bag stations which are installed to prevent dust to disperse in surrounding .
