Material
Dry Pasta
Answer in brief
Pasta leaves the dryer at full value and loses it one drop at a time.
Short shapes break at impacts, long shapes bend and snap, and the fines end up as a dusty, unsellable fraction at the bottom of every container.
- Match the conveying method to the shape rather than to the line layout.
- Keep drops short and cushioned.
- Collect fines deliberately, since they are both a loss and a dust source.

Handling challenges
Pasta is a bulk solid whose behavior changes completely with the shape, and one plant usually runs many shapes.
Shape decides the system
- Short shapes behave like a free-flowing granule and tolerate belt and vibratory conveying.
- Long shapes have to stay aligned and are handled on belts and in channels rather than in bulk.
- Nest and sheet products are effectively handled as individual items.
Trying to run every shape through the same bulk system is where breakage statistics come from.
Breakage
Dried pasta is brittle, and the energy at a transfer point is enough to snap it.
Low drop heights, soft let-down chutes and vibratory conveyors with controlled stroke protect the piece count.
Moisture and checking
Pasta that re-absorbs moisture after drying develops fine cracks that appear as breakage later.
Conditioned air between dryer and packing and short holding times limit the problem.
Fines and dust
Flour dust and pasta fines are combustible, and the collector in a pasta plant deserves the same assessment as in a mill.
What to establish before buying equipment
- Shape list and the one with the worst breakage behavior.
- Acceptable breakage percentage at the packer.
- Bulk density per shape, which sets weigher and box sizing.
- Allergen matrix where egg or gluten-free products share the line.
Material behavior
- Flowability
- Shape dependent; short shapes flow, long shapes do not
- Abrasiveness
- Low
- Cohesiveness
- Low
- Moisture behavior
- Hygroscopic; re-absorption causes checking and cracking
