Flour handling system- pneumatic conveying
Flour bags are tilted to screw conveyors and its
passes through vibrating screen .
Flour then is passed on to big storage silos .Flour
is conveyed through s.s pipes .Pressurised air
helps it to travel from loading point to silos .
Screw or lobe type compressors are used for these
types of application .These silos have level sensors which
stops compressor once the silos are filled at maximum
From silos the conveyors are used to bring flour
through screw feeders to weigh hopper where desired
weight of flour is then discharged into
In case moisture contents is higher than normal then
flour has tendency to stick to the pipelines and in extreme cases block the pipelines . Pneumatic vibrators are used in
various points to avoid this type of situation .
Fluidised bed of flour can be used to transfer flour directly from bulk silos which are transported from flour millers .
Agigation is created in these kind of silos which are then carried to silos of plant .
Bulk handling of flour has following advantages Fat Handling
1. Transportation cost is saved
2. We can have uninterrupted production
3. We can negotiate better price from vendor a we would getting bulk volumes from them
4. The most important factor we would be saving substantial amount of cost on behalf of
labour which are involved in loading and unloading .
5. Wastages are less Flow diagram for Bulk Flour Handling
