In-Line Ultra Hygienic Mixers
In-Line Ultra Hygienic Mixers
The Silverson Ultra Hygienic series of multipurpose In-Line mixers is able to perform the widest variety of applications - mixing, emulsifiying, homogenising, disintegrating and dissolving, with an efficiency, flexibility and hygienic construction unmatched by other machines.
UHS range mixers are 3-A TPV (Third Party Verification) Certified and are fitted with EHEDG Certified Mechanical Shaft Seals, fully EHEDG certified models are available. They are designed to comply with both FDA and cGMP guidelines.
Features:
- Self-pumping
- Aeration free
- No bypassing
- Interchangeable workheads
- Self-draining tangential outlet
- Ultra Hygienic single mechanical shaft seals, easily converted to double mechanical shaft seals
- No manual dismantling and cleaning is required, significantly reducing maintenance, operating cost, increasing reliability and increasing productivity.
How It Works
Silverson’s line of high shear In-Line mixers offers a great many advantages to the processor - speed, versatility, self-pumping, aeration-free, guaranteed efficiency. At the heart of every mixer is Silverson’s high performance rotor/stator workhead.
The high-speed rotation of the rotor blades within the precision-machined mixing workhead exerts a powerful suction, drawing liquid and solid materials into the rotor/stator assembly.
Centrifugal force then drives the materials towards the periphery of the workhead where they are subjected to a milling action in the precision-machined clearance between the ends of the rotor blades and the inner wall of the stator.
This is followed by intense hydraulic shear as the materials are forced, at high velocity, out through the perforations in the stator, then through the machine outlet and along the pipework. At the same time, fresh materials are continually drawn into the workhead, maintaining the mixing and pumping cycle.

Mixer Options
UHS Range
Silverson In-Line Ultra Hygienic mixers offer further versatility with multistage rotor/stator configurations as standard options, resulting in substantially faster mixing times by reducing the number of recirculation passes required and offering greater particle size reduction. Self-pumping throughputs of up to 200,000 litres per hour.
Verso UHS Ultra-Hygienic Mixer
The Verso UHS is an Ultra-Hygienic version of the standard Verso machine, allowing it to be used for stringent applications in the Pharmaceutical and Biotechnology industries as well as Food, Cosmetics and other clean industries.
Workheads
A comprehensive range of workheads and screens is available for all Silverson high shear mixers. These easily interchangeable workheads offer great versatility by allowing any machine to be adapted to perform a wide range of mixing operations including emulsifying, homogenising, disintegrating, dissolving, dispersing, blending, particle size reduction and de-agglomerating. Changing from one head or screen to another is quick and simple.
General Purpose Disintegrating Head
Used for a wide range of applications, this head will give the greatest throughput. Suitable for the blending of liquids of similar or greatly varying viscosities, its uses include the disintegration of solid and semi-solid materials.
Square Hole High Shear ScreenTM
The configuration and fine internal tolerances of this stator provide exceptionally high shear rates which are ideal for the rapid size reduction of soluble and insoluble granular solids. It is also suitable for the preparation of emulsions, gels and thickeners and fine collodial suspensions.
Slotted Disintegrating Head
For the disintegration of fibrous materials such as animal and vegetable tissue, as well as the disintegration and solubilisation of “elastic” materials such as rubbers and polymers.
Emulsor Screens
These screens are suitable for liquid/liquid preparations and are especially useful for all emulsions. Emulsor screens are available in fine or medium perforations.
