MIXING: This is a process where all ingredients are put together in right proportion for

dough formation.These ingredient are then fed into Mixers where mixing is done and

dough is prepared for molding .Major ingredients are flour , fat ,sugar and others as per the

product one would like to have.Dough temperatures play important role in biscuitmanufacturing .Next important factor is mixing time . Mixing time depends upon flour

characteristics.Normally mixing time is between 10- 15 min and is performed in two or

thres stages with different mixing speed .

MOULDING: In this section we laminate the dough into sheet which then passes down to

gauge rollers and sheet thickness is achieved for cutting . Here we have a cutter or a

moulder as per the variety where one gets the shape and sizes of biscuits .Moulder /cutter

speed again depends on different variety of biscuit.Moulders are used for short dough typeof biscuit and cutters are used for sheet variety or hard dough .

BAKING: This is the area where we pass these moulded wet biscuit into baking oven .The

biscuits are baked on desired temperature s.Various type of heating are available now days

as per the convenience and cost .Different type ovens are available like direct fired ,indirect fired and hybrid ovens .Heating of biscuit is done by conduction , convection and

radiation inside the oven .Dampers are provided to control moisture inside the ovenssection . Different heating profiles are maintain for different varities of biscuit . Normally

ovens are classified as 4 zone , 5 zone or 6zone ovens where length varies from 40 mtr to

80 mtrs . Biscuits are carried on wire mesh band in oven . Baking time are different

COOLING: These baked biscuits are then passed on to cooling conveyors for natural

cooling prior to packing .The temperatures are brought down to room temperatures .The

length of conveyor is sometimes 300 - 400 ft . Cooling conveors can be of two deck or 3deck type as per space availability . Natural cooling is prefered over forced cooling as it

maintains the texture quality of biscuit .

PACKING: These biscuit are then stacked and fed into packing machine for packing.

Different packing material are available for packing of these biscuit in different packs .slug

packs , pouch pack or family packs etc. These packs are then put into secondary packaging

like cartons to be transported to retailers.Packing material used for biscuit packaging areBOPP ,Laminates ( pearlised or metallised ) ,Pouches .
