Anti-Caking and Free-Flow Agents

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.  Anti-caking and Free-flow powder agents are part of the engineered line of Silica carrier agents from Huber Engineered Materials that will improve the flow behavior and storage stability of a broad variety of food products.  Use Huber silica carrier agents to: 

  • Free-flow AgentsPrevent caking
  • Improve flow and increase packaging rates
  • Reduce or eliminate build up in spray drying operations
  • Decrease Dusting
  • Eliminate lumps
  • Efficiently absorb liquids, fats, and oils for powdered food applications
  • Decrease clogging and bridging during production



Silica Carrier AgentsAnti-Caking and Free-Flow Agents: Huber 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 non-aqueous binding of powder particles.  Huber Silica products are ideal for use in Chili Powder, Powdered Eggs, Salt, Seasoning Mixes and many other food applications.  To learn more about how Huber scientists work with our customers to solve free-flow problems, read our formulation guidelines.

The ease of handling highly viscous or highly reactive products 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.


Process Aids: Huber's products for food applications make manufacturing more Anti Caking | Free Flow Agents |Silica Carrier Agents | Silicaefficient 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 Huber utilizes 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 Huber carrier product saves time and money!
