Silverson - Top Feed High Sheer Mixer

• Emulsifying and homogenising ingredients for sauces, dressings, and dairy products.
• Disintegrating solids and dissolving powders into liquids for beverages and confectionery.
• Blending and dispersing viscous products such as purées and pastes.
• Creating stable suspensions for various food formulations.

Typical capacity

For this class of equipment, capacities commonly range from laboratory scale (a few litres) up to industrial volumes of several thousand litres, depending on the specific model and motor size.

Power supply

Units of this type typically require a three-phase electrical supply, commonly 400V, 50Hz in the UK, with motor power varying significantly based on capacity and application.

Shear rate

High shear mixers are designed to achieve very high shear rates, typically measured in m/s, to rapidly reduce particle size and create fine emulsions.

Materials of construction

Contact parts are commonly manufactured from 316L stainless steel to meet food hygiene standards, with other non-contact parts often being 304 stainless steel.

Mounting

Top feed mixers are typically mounted directly over the processing vessel, either on a mobile stand or a fixed gantry.

Rotor/stator configuration

Most high shear mixers feature an interchangeable rotor/stator workhead, allowing for different levels of shear and processing actions.

• What is the primary benefit of a high shear mixer over a standard agitator?

  A high shear mixer provides significantly more intensive mixing, capable of creating fine emulsions, homogenising immiscible liquids, and rapidly dissolving solids, which standard agitators cannot achieve.

• Is this mixer suitable for viscous products?

• How is the shear rate controlled on these units?

• What maintenance is typically required for a high shear mixer?

• Can this mixer handle abrasive ingredients?

Lab mixers and stirrers hold strong reputations for reliability and durability. Buyers typically prioritise motor condition, speed range suitability, and vessel compatibility when purchasing used units. The equipment category is valued for consistent performance across research and production settings. Key strengths include robust construction, straightforward maintenance, and long operational lifespans. Corrosion resistance of wetted parts merits careful inspection. These devices remain dependable workhorses in pharmaceutical, biotech, and laboratory environments, offering solid value when sourced from reputable sellers with clear service histories.
