SIPERNAT SPECIALTY SILICA in the animal feed industry
WHAT CAN SIPERNAT SPECIALTY SILICA DO FOR YOU? Handling is becoming an increasingly important issue for feed additive processors, whose customers prefer products that can be dispensed with precision and certainty in automated processes. The most suitable options here are freely flowing powders or microgranular products that do not cake or form dust. Achieving these characteristics means having to convert liquid substances or pastes into freeflowing powders. It also means maintaining flowability for powdered substances and preventing them from caking. Evonik has developed special SIPERNAT grades for both applications. The advantages for you and your customers: Dust-free concentrates Freely flowing powders Protection against clumping Can be dispensed with precision Consistent quality Saves money 2 L+L 17-01-075 IB Sipernat - eh.

SIPERNAT specialty silica helps you as an absorbates manufacturer to convert liquid or paste feed additives into free-flowing powders Many of the additives used in animal feeds, such as vitamins, organic acids, choline chloride solution, pigment dispersions, and antioxidants, are liquids and have to be blended into a powdered or granulated feed premix in subsequent processing steps. As an absorbates manufacturer, you deposit these liquids onto carriers so that the valuable additives can be dispersed homogeneously. Your customers want a freeflowing powder or granulate that they can blend with other dry substances in any given proportion. SIPERNAT specialty silica has long proven to be an outstanding carrier in these types of applications. A highly absorbent, freely flowing, chemically inert, physiologically harmless material, SIPERNAT specialty silica yields a finished absorbate consisting of 50 70 % active agent, whose particle shape and handling properties are determined by the carrier silica. Evonik has developed its SIPERNAT 2200 grade silica specifically for producing dust-free absorbates.

As a premix manufacturer, SIPERNAT specialty silica keeps your premixes free-flowing and protects them from caking As a premix manufacturer, you want to provide your customers with a freely flowing powder or granulate that does not tend to form lumps even when in storage. Mineral premixes, vitamin premixes, and other powdered feed additives, however, do not flow well enough on their own. The addition of 0.5 2 % of a hydrophilic or 0.1 0.5 % of a hydrophobic SIPERNAT product significantly improves flowability and reduces the tendency to cake. This allows users to dispense these valuable feed additives evenly, makes processing easier, and prevents costly downtime. Figure 4 shows the effect of hydrophilic SIPERNAT 22 S with copper sulfate, which is often used in mineral premixes. SIPERNAT 22 S and SIPERNAT 50 S, or of AEROSIL 200 F, a fumed silica, yield excellent results as well, although this requires somewhat higher concentrations of additive (0.1 1.0 %). Along with reducing the tendency to cake, addition of SIPERNAT specialty silica and AEROSIL fumed silica also improves flowability, as is the case for threonine (shown in diagram 2).

SIPERNAT D 17 is particularly efficient, as the hydrophobic nature of the silica inhibits further water uptake. Even concentrations of just 0.05 0.25 % are enough to make a significant difference, considerably improving the long-term stability of amino acids, especially during shipment or storage.

Certain silica products are also available in semi-bulk packaging known as FIBCs (flexible intermediate bulk containers). FIBCs can be emptied without creating dust, require fewer labor utilization (compared to paper bags), and eliminate potential contamination risks because they are closed. Synthetic silicas can still be shipped as loose bulk materials as a cost-effective alternative. Figure 5 Additional information on packaging types is available from Technical Information sheets 1232 ( Packaging Types for Performance Silica ) or 1321 ( Semi-Bulk Packaging for Finely Dispersed SIPERNAT Products ). Customers can easily handle these products without creating dust, and process (i. e., convey, measure out, blend, etc.) them within solid or liquid systems. More detailed information on handling synthetic silicas is available in our Technical Bulletin Issue 28 ( Handling Synthetic Silicas and Silcates ).

Storage SIPERNAT products are largely chemically inert and their composition does not change, even over long periodes of time. However the relative large surface area of these products can lead them to adsorb volatile substances. In the case of moisture, this adsorption process is reversible. For this reason we recommend storing all SIPERNAT products in a dry location where they are protected from moisture or other organic vapors. For more detailed information on the stability of synthetic silicas, please request the corresponding product information. SIPERNAT products stored over long periods of time may exhibit signs of modest compression. This can elevate their tamped density slightly and result in changes to product characteristics. For more detailed information on product packaging/ handling, please contact your local sales organization.
