Rotary Moulder (RM400)

Designed to form short/soft dough cookies with repeatable shape definition and clean release. The RM400 presses dough into an engraved forming drum, extracts pieces onto a cotton canvas belt, and transfers them onto standard 400 × 600 mm trays.

Rotary moulding is typically selected when you want a defined surface pattern (for example petit beurre style) while minimizing deformation during transfer. Consistent results depend on dough plasticity, stable feeding, and correct scraper/stripper settings.

Process & adjustment guide (practical)

  • Scraper/stripper knife setting: Too high can cause incomplete cavity filling and weak definition; too low can lead to overfill and tails during extraction. Fine adjustment is typically done with the production dough.
  • Speed balancing: Drum speed and conveyor (canvas) speed should be synchronized so the piece releases without stretching or distortion.
  • Dough condition: If the dough is too dry/crumbly, cavities may not fill; if too soft/sticky, release can be difficult and definition can suffer. Small recipe or temperature changes often make a visible difference.
  • Changeover: Different biscuit designs are produced by changing the engraved forming drum. Cleanability and repeatable settings help reduce downtime between recipes.

The machine can be equipped with a tray feeder and tray conveyor. Rotary moulding avoids cutter scrap recycling that is typical with sheeting-and-cutting lines, and it is commonly used when a defined surface pattern is required on the biscuit.

Frequently Asked Questions

Answers to common questions about AkayGAM rotary moulder (RM400).

What dough types can a rotary moulder form?

Rotary moulders are mainly used for short/soft dough where dough can be pressed into engraved cavities and released cleanly onto a cotton canvas or transfer belt. Dough plasticity, fat level and moisture balance affect cavity filling and release.

How does the scraper/stripper knife setting affect the cookie shape?

Knife height and angle influence cavity fill and release. Too high can cause incomplete filling or weak definition; too low can lead to overfill and tails. Final setting should match dough consistency and engraving depth.

How is weight consistency controlled on a rotary moulder?

Consistency depends on stable dough feeding, correct forcing roll pressure, synchronized drum and conveyor speeds, and repeatable scraper settings. Keeping dough temperature and plasticity stable improves repeatability.

Can the forming drum be changed for different biscuit designs?

Yes. The engraved forming drum can be changed to produce different shapes and surface patterns. Quick-change and easy cleaning reduce downtime between recipes.
