SEMOLINA DETACHER

Pin-technology passage-efficiency and ash-reduction unit

A high-performance mechanical break-up unit for raising the sieving efficiency of specific passages and the flour-extraction quality in flour- and semolina-milling diagrams. After the rolls, it disperses the endosperm particles stuck to fine and medium semolina without damaging the molecular structure, thereby raising flour purity and radically lowering the final ash content.

WORKING PRINCIPLE

Intake from the pneumatic line’s upper bend — compact in-line integration: depending on the layout, the device can be suspended from the ceiling and positioned like an “elbow” at the upper bends of pneumatic conveying lines, joining the product flow directly without taking extra space.
Fixed and rotating disc pins — round upper, square lower: the incoming semolina mass is guided between two discs — one fixed and one rotating at high speed; the round and square pins on the discs instantly break up the agglomerates with high-frequency mechanical impacts.
Ash optimisation and discharge — optimal particle-size distribution: the semolina that has passed between the pins is fully cleared of the bran and micro-dust it was stuck to; the product, its endosperm structure freed, is sent to the next sieve passage, and the improved sieving quality prevents bran from mixing into the flour and minimises ash content.

KEY ADVANTAGES

• Design and space saving (ceiling-mount flexibility): Its compact body lets it be mounted at pipeline corner bends practically as an elbow element, fully removing the need for an extra frame or floor space on the plant levels.

• High wear resistance (heat-treated): All round and square pins on the discs have undergone a special heat-treatment to withstand high mechanical friction and reach maximum hardness; wear is minimised and the geometry is preserved for years.

• Direct ash optimisation: By perfectly scraping the floury particles stuck to medium and fine semolina, it prevents bran from escaping into the flour channel on the screen; this lowers the plant’s overall ash value and directly raises type-1 flour yield.

• Two models and flexible motor options: Two separate mechanical models and purpose-specific motor-power alternatives are available to suit the hourly diagram density and the character of the semolina processed (fine/medium passages).

ENGINEERING NOTE

The round-and-square-pin semolina breaker is the hidden hero of a mill’s middle passages in particular. The round and square pin geometry creates high-speed turbulence and an impact effect between the particles, peeling off the endosperm without breaking the bran. This fine balance is the most effective engineering way to raise the plant’s total extraction yield without harming flour quality.
