Precipitated Silica Products for the Food Industry

For more than 30 years, our Qemetica FLO-GARD^™ silica products have been engineered to meet the flow conditioning challenges associated with virtually every type of powdered, granulated, emulsified or grated food product.

Designed to prevent caking and optimize the flow characteristics of food products, Flo-Gard flow conditioning silica products enable improved product performance and manufacturing productivity by:

Imparting uniformity to irregularly shaped particles
Absorbing ambient moisture and oils from food particles
Forming micro-layers of dust on sticky particle surfaces to prevent agglomeration
Serving as a dry lubricant
Dissipating electrostatic charge between particles

For food manufacturers, the resulting benefits include:

Increased processing efficiency through smoother ingredient blending and less caking in screens, hoppers, conveyors, spray dryers and machinery
Enhanced product consistency and quality control through accurate, automated dosing of fruit and vegetable extracts, spices, nutrients, preservatives and other constituent materials
Easier packaging
Greater storage and transportation flexibility, including the ability to ship products in a variety of temperature, humidity and environmental conditions
