Sirer Arm and it’s arrangement top view.
Previous posting submitted that layer most under in CST dominant Sludge / sand but still have palm oil content that still high and necessary be strived for so that permanent apart maximal at CST although be quoted to return at sludge separator.
Because the condition is sludge dominant / sand will cause sludge has specific gravity more than 1 and at some stage will trap palm oil in pockets . Where creat palm oil pockets not be permitted because brought by sludge out from CST.
Tool that used to release palm oil pockets called Stirer Arm, stirring rod arm.
Stirring rod arm very simple, consist of steel plate welded form I profile and given hole enough so that sludge doesn't impel only smash with composed to form star if a bird's-eye view. Principal movement stirer this only rolling with constant speed 2-3 rpm. long arm in adversative direction, there side part long and moved half it shorter. This matter be made just for give informer movement variation so that supposed sludge can cracking all before sludge step into under flow.
This stirring rod arm position is this best on steam coil so that oil leas from pockets formed soon climbs surface.
Stirring rod arm form must be payed do not until cause solid under be stirred and mix with palm oil that apart with hasn't cause liquid CST come along stirring rod arm movement unidirectional rolling.
