USA—Charles Ross & Son Co.’s Batch High Shear Mixers equipped with Solids/Liquid Injection Manifold (SLIM) technology deliver powders in an efficient manner for instant wet-out and complete dispersion into low-viscosity liquids.

Charles Ross & Son Co.’s Batch High Shear Mixers equipped with Solids/Liquid Injection Manifold (SLIM) technology deliver powders in an efficient manner for instant wet-out and complete dispersion into low-viscosity liquids.

High-quality dispersions, suspensions and emulsions are thus produced in dramatically less time.

A SLIM mixer assembly with Progressive Spiral Porting creates a vacuum that draws powders directly into the high-shear zone and rapidly disperses individual solid particles into the liquid vehicle.

This method of powder addition reduces the formation of lumps, prevents floating powders, eliminates dusting and accelerates mixing time.

The SLIM can also be used to introduce minor liquid components and create fine emulsions.

“The SLIM is well-proven for hard-to-mix powders, including thickening agents like CMC, xanthan, guar, gum arabic, carrageenan, alginates, pectin and starches,” said Christine Banaszek, sales manager, Charles Ross & Son Co.

However, the ROSS SLIM, available in either batch or inline configurations eliminates these typical setbacks by accelerating the mixing process

“In conventional mixing systems, such challenging powders are added very slowly into an agitated batch — prolonged mixing is often necessary to ensure complete dissolution or dispersion.

The SLIM offers a much simpler method: rapid addition of powders without subsequent agglomeration,” Banaszek added.

Additionally, it enables a cleaner and more operator-friendly method of raw material addition, minimizing dusting in the plant atmosphere.

To raise and lower the High Shear Mixer in and out of the mix vessel, the company offers a floor-mounted design equipped with an air/oil hydraulic lift. Safety limit switches prevent operation of the mixer while in a raised position or without a mix vessel in place.

The main advantage of batch mixing is its flexibility. You can make small batches, if desired, and it is easy to make slight variations in your products from batch to batch.

Solid ingredients are quickly blended into solid fat to form a uniform mixture without creating excessive heat.

It is designed specifically for mixing high-fat, high-solid products, such as icings, batters, pastes, peanut butter, muffins, pie fillings, cake-style donuts and other fat/sugar mixtures.
