Recipe driven continuous mixer for accurate, homogeneous slurries

A slurry is a semi-liquid mixture of insoluble material in a liquid carrier. Creating and maintaining a homogeneous (i.e., uniform) slurry is vital to proper product coating and economical ingredient use. A slurry’s homogeneity is subject to several factors and the application of consistent agitation is a consideration.

Typically, tanks (i.e., mix and use tanks) hold slurry batches and are equipped with motorised agitators that keep the slurry in motion and the solids suspended. Beyond requiring significant floor space, operating a tank system can be time consuming as it relies on operators manually adding ingredients to the mix tank and then blending them until thoroughly mixed.

Most tank designs require a half or full batch for the mixing impellers to make an effective blend. Not surprisingly, the mix accuracy can be prone to human error, and unused slurry is both a waste of expensive spices and a sanitation problem if the tank is inadequately cleaned.

The Slurry On Demand Continuous Mixer can operate at a wide range of mixing speeds, up to 1,350 RPM

Slurry On Demand® Continuous Mixer

The Slurry On Demand Continuous Mixer eliminates the inherent flaws of standard mix and use tank systems. This recipe-driven, tankless, continuous mixer automatically and accurately mixes seasonings and liquids into homogeneous, lump-free slurries in the desired quantity that is required downstream, and significantly reduces wasted ingredients and operator start-up and cleaning time.

As the operator is not involved in measuring and dosing ingredients, exact quantities of ingredients are accurately dosed and ratios are maintained; resulting in minimal residual slurry at the end of a production run.

Repeatable and consistent results

Although the Slurry On Demand was designed for continuous flavoring operations, the mixer’s superior design is most prominent when running multiple flavors requiring frequent changeovers. Operators can quickly change flavors without needing to clean and to refill tanks or to prepare mixes well in advance of the product changes. With a completely accessible IP67 and NEMA 4X design and washdown-ready stainless-steel construction, operators can use their time processing, not cleaning.

An operator-friendly control system provides the processor with repeatable and consistent results, and when combined with WeighBack™ weight-based mass flow technology, the overall system delivers product within specifications almost immediately.

Versatility to adjust recipes

Increased production time combined with reduced costs from wasted ingredients means increased profit for processors. The Slurry On Demand operates at a wide range of mixing speeds (up to 1,350 RPM) so it can accommodate a large variety of slurries and this versatility gives processors the flexibility to adjust their recipes or expand a product line and grow their market share.
