The Silverson laboratory mixers offer outstanding efficiency in day-to-day work for a broad range of applications: mixing, emulsifying, dissolving, homogenising and disintegration. With a capacity from 1 ml up to 12 litres, and the ability to mix in-line with flow rates up to 20 litres/minute, it offers excellent reproducibility when scaling up to full scale production machines.

Examples of mixing heads for laboratory mixers; These are the same as those used in larger production machines.

A Silverson high shear batch mixer doesn't simply mix; it emulsifies, homogenises, solubilises, suspends, disperses and disintegrates solids. Each mixer, with its precision-engineered Silverson rotor/stator workhead, far outperforms conventional mixers, cutting processing times by up to 90%, improving quality, product consistency and process efficiency.

Silverson High Shear Batch Mixers will:
· Process from 4 to 30,000 litres
· Eliminate agglomerates and fish eyes
· Create stable emulsions and suspensions
· Reduce particle size
· Rapidly dissolve solids
· Accelerate reactions

Silverson In-Line mixers are efficient and rapid in operation, and can reduce process times by up to 90%. Easily fitted to existing processing plant, they can greatly improve product quality and uniformity. Interchangeable workheads allow any machine to mix, emulsify, homogenise, disintegrate, solubilisie, disperse, de-agglomerate and accelerate reactions.

Silverson High Shear In-Line Mixers will:
· Self-pump at throughputs from 15 to 200,000 litres/hour
· Eliminate agglomerates and fish eyes
· Create stable emulsions and suspensions
· Reduce particle size
· Rapidly dissolve solids
· Accelerate reactions

Incorporating powders into liquids and achieving a consistent homogeneous product, time after time, is one of the most difficult of all mixing applications. To meet this challenge Silverson have developed the Flashblend - specifically designed to incorporate large volumes of powders into liquids.

Features Include:
· Agglomerate-free product - Uniform, lump-free product.
· Repeatability - Consistent homogeneous product time after time.
· Minimum aeration - Keeping aeration to an absolute minimum makes the Flashblend ideal even for products that tend to foam or aerate easily.
· Speed - Powder incorporation rates up to 15,000 kilos/hour; faster than any other conventional method available.
· Improved vessel hygiene - No powder buildup - fewer CIP requirements.

Silverson's Ultramix is designed for applications that are beyond the capabilities of a conventional agitator but do not necessarily require the intense high shear of a Silverson rotor/stator mixer.

Ultramix Advantages:
· Excellent in-tank movement is provided by the dynamic mixing head, even when processing high viscosity mixes.
· The powerful vortex can rapidly incorporate large volumes of powders.
· Ultra-Hygienic design - single-shaft, single-piece mixing head - designed for clean-in-place (CIP) with sterilise-in-place (SIP) as an option.
· Full compliance with 3A, USDA and cGMP requirements.
· Low maintenance - the single-piece mixing head is of a simple, robust construction with no wearing parts or bush.
· Reduced power requirement compared with conventional high shear mixers.

Silverson's new ultra-hygienic series of high shear bottom entry mixers are designed to fit into the bottom or side of a mixing vessel. These high shear mixers are typically used in conjunction with a slow speed anchor stirrer or scraper unit for high viscosity products.

The Silverson Bottom Entry mixer gives high shear homogenisation while the stirrer/scraper distributes the homogenised output uniformly through the vessel. This is ideal for high viscosity cosmetic, pharmaceutical and food products.

Bottom Entry mixers can also be used by themselves on low viscosity products and to wet out powders. Silverson Bottom Entry mixers offer full compliance with GMP, 3A, and USDA requirements.

If you thought it couldn't be done, think again. Silverson's mighty Disintegrator 2500 mixing system will disintegrate, solubilise or disperse the largest of solids - up to 1 metre across - in a single operation, and in times you wouldn't believe.

The Disintegrator 2500 incorporates a powerful and unique Silverson mixer located in the bottom of a custom-built vessel. The mixer exerts a massive suction downwards from the surface of the liquid, pulling down even the most buoyant of solids, no matter what the size. These solids are literally ripped apart and dispersed throughout the mix, and with the refinement of a Silverson In-Line mixer included in the system, are totally solubilised or suspended.

For smaller solids, Silverson offers the Duplex Disintegrator / Dissolver, which was specifically developed for the disintegration and solubilisation of solid rubbers and polymers for the lube oil, bitumen and adhesive industries.
