AEROSIL® and SIPERNAT® products help to keep your mill clean and ensure the flowability of your fine product.
Für den Anwender von Futtermitteladditiven spielt die Handhabung eine zunehmend größere Rolle. Von Kunden bevorzugt werden Produkte, die auch in automatisierten Prozes sen genau und sicher zu dosieren sind. Besonders geeignet sind hierbei freifließende, nicht staubende und nicht verbackende Pulver oder mikrogranuläre Produkte. Um diese Eigenschaften zu erreichen, müssen flüssige oder pastöse Substanzen in fließfähige Pulver verwandelt werden. Zu dem müssen pulverförmige Substanzen fließfähig gehalten und am Verbacken gehindert werden. Evonik hat für beide Anwendungen spezielle SIPERNAT®-Typen entwickelt.
SIPERNAT® specialty silica as well as AEROSIL® fumed silica help to keep salt flowable and prevent caking. This brochure gives product recommendations.
Our products help to handle feed more easy e.g. with preventing caking. This brochure gives an overview of our products developed especially for the feed industry.
Convenient food products at high quality standards are increasingly popular. Powdered ingredients are often used in these products. Due to their fine particle size or stickiness some powders show poor flow properties and cake on storage which makes handling and proper dosing difficult. Hygroscopic substances, such as fruit powders, table salt or vegetable extracts as well as ground spices or spice mixtures are only a few of many examples. For all those ingredients AEROSIL® fumed silica and SIPERNAT® precipitated offer an efficient low cost way to meet this challenge and improve productivity.
Recommended mixing procedures for powders and granulates Specialty Silica have found their way with numerous applications into many branches of industry. This also applies to their use as carrier for liquid or pasty substances as well as the application as flow aid for powdered or granular products. Due to their fineness and low bulk density mixing with other ingredients is somehow sophisticated. This Technical Information gives some recommendation on suitable mixing equipment and how to use it, when Specialty Silica are concerned.
Powdered ingredients are used increasingly in many industries. A good flowability is the prerequisite for handling powders properly, discharching them easily out of a silo and dosing them exactly. However, many powders are highly cohesive and the proper processing thereforce is a challenge. Additionally many powders tend to cake on storage or while being transported due to climate conditions pressure.
AEROSIL® fumed silica and SIPERNAT® specialty silica are essential for smooth manufacturing of a high quality instant beverage. Good flowability and lack of caking tendency of the used dry ingredients and the final mixture are of the utmost importance. Excellent flow behavior of all compounds is crucial for manufacturers for accurate dosing and processing of powders. For consumers ease of handling of the instant drink is favorable, too; as this means increased convenience. Minimized caking tendency is important for retaining the quality of the instant beverage, even under sometimes adverse storage conditions in foodservice restaurants or at the consumer’s home. When caking of ingredients in the powdered beverage is inhibited, it might be possible to reduce the moisture barrier in the packaging, thus helping to reduce packaging costs.
Various factors must be considered, when choosing the right flow and anti-caking aid for spices and seasoning. Depending on your product and the specific manufacturing process, the type and dosage of the added Performance Silica needs to be carefully selected. When free-flow and caking-inhibition during storage is key for you, AEROSIL® 200 F or SIPERNAT® 50 S could be suitable options. If dust-minimization while improving the flowability is important at your plant, formulations including AEROSIL® 200 F or SIPERNAT® 350 or SIPERNAT® 22 S should be tested. For maintaining the colour and good flowability SIPERNAT® 350 or AEROSIL® 200 F are successful options.
SIPERNAT® specialty silica and AEROSIL® fumed silica can improve the spray drying of many difficult-to-spray dry materials. These include chicken or beef purees, HVP (hydrolyzed vegetable protein) containing formulae, yeasts and whey extracts, pet food flavors, dairy products, hygroscopic flavors, and many more.
SIPERNAT® Specialty Silica and AEROSIL® Fumed Silica are referred to as a “carrier” when they are used to hold and absorb liquids in the production of a dry, free-flowing powder. Any size silica product can be used as a carrier; making either coarse or fine absorbates.
To ensure a convenient as well a efficient handling of sugars without time and resource consuming measures to break agglomerates again, it is important to reduce caking and avoid formation of lumps reliably.
Powders of soft materials such as fats, milk powders with high fat content, non-dairy creamers or emulsifiers are especially challenging in handling and transport. Particularly on long term storage or on long transportation time they tend to cake significantly. The problem becomes even worse when soft products are exposed to changing temperatures or pressures because soft or thermoplastic powders are deformed at rising temperatures or applied pressures. Comprehensive studies on soft and fat powders showed how AEROSIL® fumed silica and SIPERNAT® specialty silica improve the performance of high fat containing and soft powders.
