HOW TO READ THIS MODEL

The system, explained.

A decanter uses a rotating bowl and a screw conveyor to separate and convey material. Alfa Laval describes denser solids moving toward the bowl wall while the scroll, turning at a different speed, carries them toward a conical beach. This static cutaway separates the bowl, scroll, feed tube and collection regions so their roles can be inspected. Compare its continuous helical flight with the conical plates in our disc-stack model. The illustrations explain different equipment arrangements; they are not interchangeable machine selections.

Model scope and limits

Original generic static teaching assembly with invented proportions. Distinct parts and outlet boundaries do not establish a complete operating flow path. No speed, setting, feed suitability, balance, efficiency, pressure rating, maintenance procedure, workplace qualification or named facility is represented. This is not manufacturer CAD or a product endorsement.

GUIDED COMPONENT STUDY

Trace the system.

Read each explanation, then focus its component in the explorer. This is a learning route through the model, with no operating or maintenance sequence.

  1. Reveal the whole bowl

    The delivered model retains a complete hollow wall. Reveal or section controls expose the internals; the illustrated cutaway does not describe a permissible access condition.

  2. Follow one continuous flight

    This single helical ribbon runs along the horizontal hub and narrows toward the conical end. Its pitch and clearance are invented teaching proportions, not a conveying calculation.

  3. Find the central feed illustration

    A hollow blue tube enters the hollow hub. Four separate openings appear in the hub downstream of its end. These geometric openings do not demonstrate distribution or throughput.

  4. Distinguish the conical end

    The hollow taper surrounds the narrowing end of the scroll. Its angle and length are illustrative; no liquid level, solids dryness or equipment selection is specified.

  5. Separate the receiving regions

    This removable ring sits at the liquid-end plate, separate from the receiving region at the opposite end. Open lower boundaries make the illustrated roles distinguishable without simulating a stream.

  6. Recognize a drive boundary

    The gold interface marks a drive location. The model has no transmission, differential-speed control, motor sizing or operating rotation.
