helps customers choose the right mixer or customises one for their particular application. Knowledge of variables such as raw material characteristics, end product viscosity, batch size and mixing temperature is used to determine the best mixer for each application.
Test facilities
In addition to its trial programme, Silverson maintains two dedicated test facilities - one in the USA in the UK - each equipped with a complete range of laboratory and production scale machines.
At either of these sites, customers can test their applications, try out new products and discuss specific applications with the technical staff.
“We are confident that once a customer tries our equipment, we’ll be able to help them optimise their processing,” says Smith. “Our high shear mixers can often reduce mixing times up to 90 per cent compared to conventional mixing equipment.”
With its MTI Eco-line heating/cooling mixer combination and the radically new Cool tec cooling mixer, MTI Mischtechnik is also firmly focused on minimising energy consumption.
As a result, they provide a high cost-efficiency in the production of dry blends and wood plastic composites (WPC) compounds as well as in other heating and cooling processes – without compromising on product quality.
By combining this equipment with an automatic raw material feeding system, a very efficient heating-/cooling mixer combination with high specific throughput rates can be achieved, says the company.
The new mixer combinations are designed for batch sizes from 60kg up to 1000 kg and throughputs of up to 7500kg/h. Typical uses include compounding of PVC-U for volume-market products such as pipes or profiles, PVC-P for highly filled recipes, and other applications without frequent product changes.
MTI says the Eco-line mixers offer a particularly advantageous combination of high throughput, low energy
consumption and attractive pricing, due to careful match of mixer sizes and required
High speed separation S
WECO’s latest in high speed separation, the SWECO Super
MX Separator, is currently available in 48- and 60-inch diameter machines. This separation system provides its users with forces as high as 10 Gs and speeds up to 2200 RPM.
“This unit was a response to a market need for a high G, high-speed version of the premium

SWECO Round Separator line,” explains Joe Smith, SWECO Senior Engineering Manager. “The Super MX provides a heavy-duty option for those customers who require an aggressive separator for their process”, Smith continues. A few of the features of the Super MX include an external conical motor
tube gusset, 5 HP motor with extra large bearings, heavier springs, thicker frames and spouts, and heavier weight guards.
The Super MX has been successful in several applications including various vegetables, toner powders, fine mica and metal powders. SWECO serves the minerals, chemical, food, pharmaceutical, paper and many other industries with a complete line of separation, sizing and milling equipment. ■

mixing power, the use of highly efficient electric drives and optimised usage of cooling water. “Therefore, a changeover from externally sourced dry blends to in-house compounding may pay off after a very short time,” notes the company. For its part, the Cool tec system has been developed in
cooperation with Reisner, one of the leading manufacturers of cooling and refrigerating equipment. Offering 30 per cent higher cooling capacity than the existing MTI standard, the Cool tec mixer offers a huge energy-saving potential (up to 25 per cent) and hence, substantial mixing cost savings to the customer.
Key brands SPX has once again used the annual FoodPro exhibition in Australia to present the latest developments in its key brands, including APV, Waukesha Cherry-Burrell, Gerstenberg Schröder, and Anhydro. Among the products being highlighted, SPX showcased its
new CIP Midi system, Flexmix Liquiverter and Consistator technologies. The APV CIP MIDI System is designed to accommodate
an optional rinse water recovery tank, where the water used for the final rinse is reclaimed to use for the first rinse of the next wash cycle, thus saving considerably on water and effluent. An additional option provides for a separate rinse water
tank which can be used in high-spec applications (for example pharma or bio-tech) to provide high purity final rinse water. The Flex-Mix Liquiverter is a square-shaped tank with a bottom-mounted, high-speed mixing impeller. The impeller generates an axial flow, which is re-circulated in the tank via the surrounding mixing chamber. This generates high shear forces and turbulence, ensuring effective and homogeneous mixing.
Light to medium processing The GS Consistator series of scraped surface heat exchangers comprises a line of durable, high-quality machines designed exclusively for light- to medium-duty processing. The units are designed to avoid thermal or mechanical damage to the product (Fig. 1), creating a wide range of products such as chocolate products, cream cheese, quark, ghee, vanaspati, vegetable spreads, filling creams, ketchup, soup and sauces with particles and starch products. ■
