Anti-caking, carriers & flow aids
For the Food Industry
Moisture, pressure and temperature all adversely affect powdered and granulated products. These conditions can make products cake, lump, bridge, clog equipment and cause packaging and performance problems. Use our silica to:
Improve flow and increase packaging rates
Reduce or eliminate build up in spray drying operations
Efficiently absorb liquids, fats, and oils for powdered food applications
Decrease clogging and bridging during production
Anti-Caking and Free-Flow Agents:
Evonik silica and silicate products work as anti-caking / free-flow agents by coating the surface of the host powder, thereby reducing interparticle interactions caused by sticky particles touching one another. The absorption of excess liquids, fats and oils prevents the binding of powder particles. Evonik Silica products are ideal for use in Chili Powder, Powdered Eggs, Salt, Seasoning Mixes and many other food applications. To learn more about how our scientists work with our customers to solve free-flow problems, read our formulation guidelines.
Efficient Liquid Absorption (Carriers):
Silica carrier products absorb substantial amounts of liquids, yet they remain free-flowing with powder-like characteristics. The ease of handling highly viscous is extraordinarily simplified by using Silica carrier agents. Carrier products work by first absorbing the liquid onto the carrier. Then, when the product is put into an aqueous system, the “carried” liquid is released and ready to be activated.
Our silica products for food applications make manufacturing more by preventing powders from sticking to machinery and clumping, ensuring that they flow smoothly and quickly from one step to the next. For example, for larger particle size carriers. We utilize a unique process that provides up to higher density than the traditional nozzle spray dried silica carrier products. This high density, low dust silica, provides better handling, processing, and increased plant manufacturing capacity. The low dust also improves flow, packaging, and package sealing. Simply switching to a Evonik carrier product saves time and money!
Food Chemistry Expertise
Evonik prides itself on its ability to collaborate closely with customers, working together to determine the best silica or silicate for their formula's unique mix of ingredients. Our scientists can help you navigate the many factors to consider when choosing a silica, including particle size, absorption, dust, point of addition to mixture, and mixing time.
The value of Evonik silicas and silicates
Evonik Precipitated silica and silicate products solve common problems in the production and processing of powder products. With Evonik silica you can achieve:
Increased throughput: improved production rates can translate to increased capacity and lower unit costs
Decreased lumping: maintaining the free-flowing quality of your powders can result in less equipment maintenance, less reject or off-spec product and longer shelf life
Consistent quality: your customers can count on the consistent, improved quality of your powder products
Reduced dusting: not only will reduced dusting improve the work environment in your plant, it will also improve the ease of packaging
How do our silica products work?
Evonik silica products work as free-flow / anti-caking agents by:
Coating the surface of powder thereby reducing interparticle interactions
Interspersing and preventing interparticle interactions
Preferentially absorbing moisture to prevent bridging between particles
Absorbing oils and similar compounds to prevent non-aqueous bridging
