Disintegrator/ Dissolvers

Disintegrator/ Dissolvers

If you thought it couldn't be done, think again. Silverson's mighty Disintegrator 2500 mixing system will disintegrate, solubilize or disperse the largest of solids - up to 40" 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 solubilized or suspended.

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


How It Works

The Disintegrator 2500 is a self-contained unit of high power comprising a specially designed Silverson high shear rotor/stator disintegrating workhead set into a custom-built dedicated vessel coupled with a Silverson high shear In-Line mixer.

Disintegrator/ Dissolvers
Stage 1

The unit is charged with liquid and started. Large solids are fed into the vessel and drawn down to the workhead which will rapidly shear lumps and slices off the edges and corners. These will be drawn into the interior of the workhead, driven by centrifugal force to the periphery and further sheared by the rotor tips against the edges of the stator perforations as they are expelled radially from the head.

Disintegrator/ Dissolvers
Stage 2

Rapid fragmentation of the large solids continues until all the particles are small enough to be drawn into the workhead for further disintegration. Materials are discharged horizontally from the workhead and forced up the vessel walls. This cycle continues until all solids are reduced to granular size.

Disintegrator/ Dissolvers
Stage 3

Once the solids are reduced to granular size the self-pumping In-Line mixer is started. The product is drawn from the bottom of the vessel, processed through the In-Line mixer’s high shear rotor/stator workhead and passed back into the top of the vessel ensuring complete solution or suspension.

Bottom Entry Mixers

Bottom Entry Mixers

Silverson’s sanitary 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 homogenization while the stirrer/scraper distributes the homogenized 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 cGMP and USDA requirements.


How It Works

The advantages of Silverson’s Bottom Entry mixer over simple conventional stirrers or agitators stem from the multistage mixing/shearing action as materials are drawn through the specially designed Silverson workhead - the heart of every machine.

Bottom Entry Mixers
Stage 1

The high speed rotation of the rotor blades exerts a powerful suction, drawing liquid and solid materials downwards into the center of the workhead.

Bottom Entry Mixers
Stage 2

Centrifugal force then drives the materials towards the periphery of the workhead where they are milled in the clearance between the rotor and the stator.

Bottom Entry Mixers
Stage 3

The materials are subjected to intense hydraulic shear as they are forced out through the stator and projected radially at high speed towards the sides of the mixing vessel. Fresh material is simultaneously drawn into the workhead, maintaining the mixing cycle.

Flashblend Powder/Liquid Mixing Systems

Flashblend Powder/Liquid Mixing Systems

Dispersing powders into liquids and creating a consistent homogeneous product, time after time, is one of the most difficult of all mixing applications. To satisfy this need Silverson has developed the Flashblend, a high shear system for rapid incorporation of a wide range of powders, including problematic gums and thickeners. The Flashblend is designed to incorporate powders on a continuous and semi-continuous basis at rates of up to 30,000 lbs/hour. The system can handle a wide range of viscosities, from low viscosity products through to viscous gels.

Advantages

  • Suitable for large scale production
  • Agglomerate-free product
  • Repeatability
  • Speed
  • Minimum aeration
  • Improve vessel hygiene
  • Viscous liquids can be incorporated into the bulk liquid via the hopper. Liquid additives can also be pumped directly into the venturi.


How It Works

The Silverson Flashblend is designed to rapidly wet out and disperse a wide range of powders into liquids. The system is based on proven technology combined with new techniques which stem from specific research into powders which are difficult to hydrate. The result is a mixer which can produce agglomerate-free homogeneous dispersion at higher production rates and concentrations than previously achievable.

Flashblend Powder/Liquid Mixing Systems
Stage 1

The process liquid is pumped at high velocity into the venturi chamber and passes into the In-Line mixer. The combination of the pump, venturi and the pumping action of the In-Line mixer creates a vacuum in the venturi chamber.

Flashblend Powder/Liquid Mixing Systems
Stage 2

When powder is present in the hopper, the powder feed valve can be opened. The vacuum rapidly draws the powder down into the venturi chamber where it passes with the liquid stream at high velocity into the rotor/stator assembly of the In-Line mixer.

Flashblend Powder/Liquid Mixing Systems
Stage 3

The liquid/powder mix is then subjected to intense mechanical and hydraulic shear which ensures that it is completely dispersed and agglomerate-free. The resultant product is then passed back to the process vessel by the pumping action of the machine.

Silverson Mixer Homogenizers

Silverson Mixer Homogenizers

Silverson Mixer Homogenizers are fast and efficient and are capable of producing a fine droplet or particle size, typically in the range of 2 – 5 microns. This degree of homogenization is suitable for the vast majority of products, such as creams and ointments, lotions, sauces and flavor emulsions.

Silverson offers a range of in-tank and In-Line mixer homogenizers for these applications. The precision-machined Silverson workhead generates exceptionally high shear rates in a three stage process that rapidly homogenizes the product to the required uniformity.

For the few applications that demand submicron particle or globule sizes a high-pressure homogenizer may be required. Where this is the case, passing the product through a high shear Silverson Mixer Homogenizer first will dramatically improve throughput, process efficiency and reduce operating costs. This is because a high-pressure homogenizer works better when fed with a premix of uniform and fine globule or particle size, allowing the product to pass through the homogenizer at a much faster rate, normally in a single pass.

High Viscosity In-Line Mixers

High Viscosity In-Line Mixers

Silverson’s High Viscosity (HV) In-Line Mixers offer exceptional flow rates and the ability to process higher viscosity products. 

This is achieved by a unique and innovative “pumping rotor” design which substantially increases the mixer’s capacity when compared to standard In-Line mixers, eliminating the need for an additional feed pump when processing higher viscosity products in the food, pharmaceutical, cosmetic and chemical industries.

Features:

  • Ultra sanitary construction - based on the 3-A and EHEDG-Certified UHS mixer range
  • Self-pumping
  • Aeration free
  • No bypassing
  • Interchangeable workheads
  • Vertical or self-draining tangential outlet
  • Designed for Cleaning-In-Place

How It Works

Silverson UHS-HV In-Line mixers feature a special rotor design which provides increased capacity, and allows processing of higher viscosities.  Operation is as follows:

High Viscosity In-Line Mixers
Stage 1

The high-speed rotation of the specially designed pumping rotor within the precision-machined mixing workhead forces liquid and solid materials into the rotor/stator assembly.

High Viscosity In-Line Mixers
Stage 2

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.

High Viscosity In-Line Mixers
Stage 3

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.

How It Works

Silverson's Verso Pilot Scale In-Line mixer 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.

Verso Laboratory In-Line Mixers
Stage 1

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.

Verso Laboratory In-Line Mixers
Stage 2

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.

Verso Laboratory In-Line Mixers
Stage 3

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.

Ultramix Mixers

Ultramix Mixers

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

Ultramix Mixer Advantages:

  • Ultra sanitary design - single-shaft, single-piece mixing head.
  • The Ultramix series is designed for clean-in-place (CIP) with sterilize-in-place (SIP) as an option.
  • Full compliance with 3A TPV (Third Party Verification), USDA and cGMP requirements.
  • 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.
  • Low maintenance - the single-piece mixing head is of a simple, robust construction with no wearing parts or bushings.
  • The design is suitable for applications from aggressive chemical service to the most demanding sanitary standards and requirements.

3-A


How It Works

Ultramix Mixers
Stage 1

As the mixer rotates at high speed, the grooves on the outside of the dynamic mixing head project the surrounding product outwards with great force, creating an area of low pressure around the trailing edge of each groove.

Ultramix Mixers
Stage 2

This draws product from within the mixing head, through the radial slots to the outside, subjecting the material to a shearing action. The grooves in the head drive the product outwards into the body of the mix at high velocity.

Ultramix Mixers
Stage 3

As material is drawn out of the slots, fresh material is sucked in through the holes in the top and bottom of the mixing head; this material is then drawn out through the slots and projected back into the mix. The pumping effect of the grooves and the shear action of the radial slots ensures rapid mixing, and develops a vigorous axial flow pattern throughout the vessel.

Batch Mixers

Batch Mixers

A Silverson high shear batch mixer doesn't simply mix; it emulsifies, homogenizes, solubilizes, 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 1 to 8000 gallons
  • Eliminate agglomerates and fish eyes
  • Create stable emulsions and suspensions
  • Reduce particle size
  • Rapidly dissolve solids
  • Accelerate reactions

How It Works

The advantages of Silverson’s high shear rotor/stator batch mixer over simple conventional stirrers or agitators stem from the multistage mixing/shearing action as materials are drawn through the specially designed Silverson workhead - the heart of every machine.

Batch Mixers
Stage 1

The high-speed rotation of the rotor blades within the precision-machined mixing workhead exerts a powerful suction, drawing liquid and solid materials upwards from the bottom of the vessel and into the center of the workhead.

Batch Mixers
Stage 2

Centrifugal force then drives 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.

Batch Mixers
Stage 3

This is followed by intense hydraulic shear as the materials are forced, at high velocity, out through the perforations in the stator and circulated into the main body of the mix.

Batch Mixers
Stage 4

The materials expelled from the head are projected radially at high speed towards the sides of the mixing vessel. At the same time, fresh material is continually drawn into the workhead maintaining the mixing cycle. The effect of the horizontal (radial) expulsion and suction into the head is to set up a circulation pattern that minimizes aeration caused by the disturbance of the liquid’s surface.
