TROUBLE SHOOTING IN BISCUIT FORMING
Major problem in forming section or moulding section is to get exact weight as
per standards and and weight variations across the line .
Weight variation occurs because of improper settings of scrapper knife and
gaps between gauge rolls .
Weights can be adjusted by changing angle of scrapper knife which is placed
below cutter and forcing rollers. Opening of angle would increase the weight
and closing down angle would reduce the weight of wet biscuit .
Adjusting the gaps between rolls of gauge rolls can also help.
Dough sheets get stuck to the rollers of gauge rolls .To prevent this to
happen we can place blowers to inject hot air on sheets .
Scrap dough dont carries upto the scrap lift conveyors or wet dough piece
dont get transferred to next conveyors. To avoid such conditions steam or
wet rollers are placed underneath the cotton conveyor which then make
conveyor wet and the dough sheet sticks to the surface of the conveyor .
Curling appears on the dough sheet in case the preceeding rollers speed
are not synchronised properly .Hence the settings speed rollers is critical for
dough sheet flow .
Webs of conveyor becomes loose or get stretched due continuous stress
hence to get the tension Tightening rollers are provided to provide tension
in webs .
Others accessories that could placed after moulder / cutter are
1. sugar/salt sprinkler
2. milk spray
3. cashew/nuts/pista sprinkler
