SHOW PREVIEW: PPMA SILVERSON HIGH SHEAR MIXERS
LABORATORY MIXERS For mixing small batches from 1ml up to 12 litres, Silverson has a range of Laboratory mixers suitable for a wide range of mixing processes. All Silverson rotor/stator mixers come with a range of easily interchangeable workheads, which allow one mixer to perform many mixing tasks which would otherwise need several pieces of mixing equipment. Silverson Laboratory mixers can blend, emulsify, homogenise, disintegrate, dissolve and de-agglomerate, and mix in-line with flow rates up to 20 litres/minute using an In-Line mixing assembly. The most popular mixer in the Silverson product range, the L5M-A Laboratory mixer, features touch pad controls and a tachometer, ammeter and programmable timer. Scaling-up is a relatively simple process as all
Silverson mixers are manufactured to the same precision engineered tolerances. So anything you produce in the laboratory can be replicated in production, without the need for reformulating.
IN-TANK MIXING For in-tank mixing of volumes up to 30,000 litres Silverson supplies in-tank Batch mixer models. Capable of performing all of the same mixing process as Silverson Laboratory mixers, it is possible to reduce mixing times by up to 90 per cent when using high shear Batch mixers as opposed to traditional mixing methods such as stirrers or agitators. Small to medium range Batch mixers can be used on mobile floor stands, further increasing their versatility. The Silverson
Ultramix in-tank mixer 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
Silverson Machines has the largest capacity range from a single manufacturer and the company has been helping customers across a range of industries to improve their mixing processes. The extensive range of high shear rotor/stator mixers that Silverson manufactures means that it can help with mixing as little as 1ml, or large volumes of up to 30,000 litres and everything in between. Here is an overview of some of the most popular products in the Silverson range, which will be able to view on Silverson Machines stand (E20) at the 2023 PPMA show.
rotor/stator mixer. Ideal for rapidly wetting out powders including gums and thickeners, the Ultramix is also ideal for use in vessels with narrow openings. The vigorous mixing action is capable of moving the entire contents of vessels even in difficult shaped containers. For this reason the Ultramix offers considerable advantages for customers using IBCs (tote bins).
IN-LINE MIXER/HOMOGENISERS Silverson's line of high shear In-Line mixers offers a great many advantages to the processor - speed, versatility, aeration-free mixing, and guaranteed efficiency. Capable of self-pumping throughputs of up to 200,000 litres per hour, these mixers are ideal for continuous mixing. Silverson In-Line mixers are capable of producing a fine, uniform droplet size, typically in the range of two to five microns. This degree of homogenisation is suitable for the vast majority of products, such as creams and ointments, lotions, sauces and flavour emulsions. Finer emulsions, down to 0.5 microns can be obtained depending on the formulation and in some cases, a Silverson In- Line mixer can replace a high pressure homogeniser in the processing line. Although Silverson’s full-scale production In-Line mixers will not be on the stand at the PPMA show 2023, the company’s bench-top In-Line mixer the Verso-UHS-HV will be available to view. The Verso-UHS-HV is a laboratory-scale In-Line mixer designed for mixing high viscosity products. It incorporates the same unique and innovative ‘pumping rotor’ design as the production scale HV In-Line mixers. This substantially increases its self-pumping capacity, allowing it to process products such as gels, creams, sauces and gum solutions on a laboratory scale. A conversion kit is available allowing the
Verso-UHS-HV to be configured as an FMX5 Powder/Liquid mixer. This kit increases the versatility of the machine, allowing one mixer to be used as a Laboratory scale High Viscosity In-Line mixer or Powder/Liquid mixer.
POWDER/LIQUID MIXING For mixing large quantities of powder, Silverson developed the Flashmix. Unlike many powder/liquid mixers, which use vacuum to pull in powder, the Flashmix literally forces powder into the liquid stream. This not only allows it to disperse and hydrate large volumes of powders, it means it can be used at higher temperatures and with higher viscosity mixes - offering the advantages of high shear mixing to a wide range of applications that were previously not possible. The FMX5, the laboratory scale version of the Flashmix, is suitable for small scale manufacturing and R&D work with a typical batch size of up to 10 litres, depending on viscosity. These are just a few of the mixer options
available in the Silverson product range. You can find out more about additional models, such as the D2500 Disintegrator/Dissolver, on the Silverson website. Or visit stand E20 at the PPMA show and talk to Silverson about your mixing requirements.
