Mixing Equipment for Toothpaste/Dental Whitening Cream Manufacturing

Industry Challenge - Manufacturing Toothpaste Dental Cream

• 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 re-circulation to the mixing vessel.
• Need to increase production without expanding the facility.

Quadro Liquids Solution

• ZC1 inline 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.

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, the customer was able to reformulate and use less polymer.
• The eliminated requirement to filter undispersed powders.
• No over-processing is 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.
