Chocolate Grinding Circulation Attritors

How Circulation Attritors Work

The circulation grinding Attritor ("Q" machine) is a combination of an Attritor and a large holding tank which is generally about ten times the size of the Attritor. The unique principle of the "Q" Attritor is the high circulating (pumping) rate, which results in a faster grind and a narrower particle size distribution.

The Circulation Attritor has the advantages of good temperature control due to the large, jacketed holding tank.

Advantages of Using a Circulation Attritor:

  • Features high pumping rates that result in faster grind and narrower particle size distribution.
  • Easily grinds down to 20 microns – 10 microns.
  • Reproducible results from batch to batch.
  • Allows continuous monitoring of slurry and addition of ingredients to the premix tank at any
    time during the grinding.
  • Low power consumption.
  • Low maintenance with minimum down time.
  • Has a jacketed grinding tank specially designed for temperature control.
    The holding tank is also jacketed for greater temperature control.

Common Applications for Attritors:

  • Cocoa liquors
  • Dark or milk chocolate
  • Confectionery compound coating
  • Ice cream coatings
  • Chocolate nut paste
  • Nut dispersions
  • Spice dispersions
  • Cheese/oil dispersions

DIMENSIONS AND WEIGHTS ARE APPROXIMATE.
Circulation Attritors designated as “QL” include specially configured arms and disks.
*Pumping rate is somewhat lower with higher viscosity slurries.
**Dimensions and weights are for complete system.
