Toothpaste/Dental Whitening Cream Manufacturing – Quadro Ytron

BACKGROUND / REQUIREMENT

  • Incorporation of Carbopol and 40% Carbamide Peroxide into Glycerine.
  • Carbopol is difficult to disperse into Glycerine because the low pH Glycerine solution results in instant hydration and viscosity increase.
  • 40% by weight Carbamide Peroxide is added to the Carbopol solution in a recirculation to the mixing vessel.
  • Need to increase production without expanding the facility.

QUADRO ’ S APPROACH

  • ZC1 in line disperser, skid mounted with a dual PD pump arrangement for performance with high viscosities and high solids addition rates and automated Q-Vac vacuum powder addition system.
  • Controls to allow (3) pre-set operating points on inlet and discharge pumps
    • Carbopol addition
    • Carbamide Peroxide addition
    • Auxiliary setting

Automated powder valve with level sensors in the hopper to control powder on/off addition.

QUADRO YTRON ZC POWDER DISPERSER ADVANTAGES

  • 75% reduction in overall batch time vs. conventional in-tank mixer processing.
  • Rapid incorporation & dispersion of solids without lumps or 'fish-eyes'.
  • Improved product consistency from batch to batch.
  • Increase in viscosity, customer was able to reformulate and use less polymer.
  • Eliminated requirement to filter undispersed powders.
  • No over-processing common with conventional mixers preserving the rheological properties of shear -sensitive products.
  • Significantly reduced air entrainment.
  • Elimination of quality problems associated with cross batch contamination.
  • No excessive dusting from bag dumping into process vessels
  • No solids build-up on process vessel walls
  • Elimination of the requirement to expand the manufacturing area to increase production.
