DRYING : Removal of liquid from a solid by thermal mean ( by Heating )
Equipment : 1 } try dryer 2} tunnel tray dryer 3} turbo dryer 4} spray dryer 5}
freeze drying 6} drum/roller dryer
FILTRATION : it is an process in which solid is separated from a fluid with use of
septum (septum - medium of filtration )
Equipment : 1} filter press 2} Nutsh filters 3} edge filters 4} leaf filters 5]
membrane filters 6} Micro filtrate 7} electrostatic precipitators 8 } wet
scrubber
SIZE REDUCTION : Reduce in size of raw materials by methods include Crushing,
Grinding, Pulversing, Shredding, Cutting.
Equipment : 1} hammer mill 2} tumbing mill 3} fluid energy mill 4} roller mill 5}
edge and end runner mill 6} cutter mill
SIZE SEPRATION : Particle of desired size separated from other fractions
Equipment : 1} sedimentation tank 2} elutritor /zigzag sifter 3} mechanical
classifier 4} cyclone separators
MIXING : complete intermingling of two or more dissimilar portion of material
so that final product obtain desired level of uni formality
Equipment : a ) Batch mixing equipment 1} mechanically agitated vessel 2} jet
mixers
