SILVERSON’S ‘HOW TO’ VIDEOS SHOW YOU HOW TO GET THE BEST RESULTS FROM YOUR INGREDIENTS
CREATING EMULSIONS Making emulsions is another difficult mixing application which Silverson has covered specifically for food, cosmetic and pharmaceutical applications. Emulsions can be challenging as the two phases will separate if not mixed correctly. When forming an emulsion, the mixing
equipment must be able to reduce the droplets in the oil and aqueous phases until they are uniform and homogenous, failure to do so will result in an unstable emulsion. Silverson mixers are ideal for this
Silverson Machines has released a series of ‘How to’ videos on its YouTube channel, intended to demonstrate how to get the best results from key ingredients using Silverson mixers
T
he series includes ‘How to’ information on applications such as
dispersing starch, manufacturing smoothies and forming emulsions, making them useful tools for those working in the food, pharmaceutical, chemical and cosmetic industries. Silverson began producing video content
to show and instruct how to get the best results using high shear technology. Although Silverson has previously produced videos on the capability and range of its mixing equipment, the ‘How to’ series is intended to reach out to those who are unaware of Silverson and help them improve their mixing. With over 70 years’ experience, Silverson
is hoping to help a new set of customers with their mixing requirements. By focusing on what people are searching for online, ‘How to dissolve sugar without heating the water’ for example, the videos are targeting a new audience of potential customers searching for answers to mixing problems which Silverson mixers can easily solve. Harold Rothman, Managing Director of Silverson, said: “Videos are very demonstration friendly, allowing the viewer to quickly understand the benefits of Silverson mixers.”
MIXING GUMS AND OTHER FUNCTIONAL INGREDIENTS Silverson receives large numbers of enquiries about common mixing problems such as dispersing Xanthan gum, mixing Carbopol and dissolving sugar, which are all included in the series. With sugar, for example, a

Silverson mixer can produce a 66 brix solution without having to heat the water – the video shows how it can be done. Diluting High Active Surfactants is one of the more challenging mixing applications in the cosmetics and toiletries industry. When added to water using conventional mixers, you often get stratification in the mix, with globules of the high viscosity surfactant remaining undiluted. In the ‘How to’ video, Silverson demonstrates how its mixers can help. Surfactants such as Sodium Laureth Sulphate, also known as SLES, can be supplied at a concentration of 25 – 28% or in a High Active form with a concentration of 65 – 70%, which needs to be diluted correctly or it can form an unprocessable solid. The video shows how pumping the surfactant into the water stream just prior to a Silverson In-Line mixer blends the liquids immediately on contact in the rotor/stator workhead, resulting in a homogenous, uniform mix.

application as the more shear energy introduced into a mix, the finer the droplets will become, ensuring that the phases won’t separate. Silverson mixers can be used to prepare both the dispersed and continuous phases and can easily create emulsions with a droplet size of 2 to 5 microns. The ‘How to’ series features a number of
videos on emulsions including making cosmetic creams, food emulsions and pharmaceutical ointments. The videos demonstrate how using a Silverson Batch mixer for smaller volumes or a Silverson In-Line mixer for larger volumes, will create stable, homogeneous emulsions.

DISPERSING SPECIALIST INGREDIENTS Silverson’s versatile mixing equipment can also solve problems which arise in more specialised applications such as dispersing Bentonite and Titanium Dioxide. Titanium Dioxide is a pigment widely used for its brilliant white opacity in products such as paints and tablet coatings. It is normally supplied in pre- micronised powder form, but the particles tend to re-agglomerate when added to liquid, forming agglomerates many times larger than the desired particle size which conventional agitators cannot break down. In this video you can see how the
Silverson mixer reduces the particles back down to the desired particle size with each pass through the rotor/stator workhead, resulting in a uniform, agglomerate-free mix. Silverson is continuing to expand the
collection of videos which will all be available on its YouTube channel. To view the videos, visit:
