New mixers and blenders increase efficiency, consistency
Tetra Pak said its new R370-1000D mixer offers customers unparalleled ingredient-mixing performance with lower operating costs. Featuring a new design that produces finer, more consistent and stable emulsions, the R370-1000D reduces the need for downstream homogenization, delivers a better-quality end product and cuts energy consumption by up to 90%. The R370-1000D features a built-in deaerating system, a flexible powder introduction system and a newly designed mixing head. This allows the new machine to handle the highest viscosities for a recirculation mixer, at up to 2,000 centipoise with up to 65% dry matter, and break the size of the droplets to 1 micrometer, significantly smaller than the industry average of 5 micrometers.
SPX Flow Inc. said its APV Cavitator helps dairy processors achieve effective hydration. Stabilizers only need to be added to a blend tank with a simple agitator and then pass through the Cavitator to achieve instant hydration. The Cavitator increases productivity and plant uptime as less time is required in holding tanks waiting for hydration to occur. In addition, use of the product means filters and strainers won’t become clogged in the process lines. In previous systems, nonhydrated lumps of gum frequently led to clogging. The Cavitator also saves energy, as there is no need to heat up water for mixing and subsequent cooling after hydration. The small footprint of the Cavitator also allows it to fit into existing production sites easily. The full hydration of added stabilizer systems lowers the amount of high-priced ingredients in recipes, which results in additional economic benefits.
HIGH-SPEED CONTINUOUS MIXING
Powder Process-Solutions’ (PPS) mixing system was custom designed to provide a specific percentage of proteins in the end product. The two PPS-designed sanitary screw feeders on top of the mixer utilize loss-in-weight technology to provide the precise amount of material to the mixing chamber. Both screw feeders meet 3A Sanitary Standards. PPS’s mixing system optimizes mixer performance, mixture uniformity and sanitation. The product offers continuous- and batch-mixing systems. PPS said its extensive experience with upstream and downstream process requirements enables the company to select and integrate equipment into a new or existing process.
EFFECTIVE SOLID-LIQUID MIXING
IKA said its CMX 2000 inline mixer incorporates solids into liquids and mixes these materials reliably and consistently in a batch process. Its multi-level design and unique pumping stage enable processing of high-viscosity products without any additional aggregates. This enables extreme suction rates and minimal production times. The CMX 2000 system is usually supplied with a solid material dosing feeder and mixing containers. Depending on the application and the requirements of the customer, the solid material can be fed via a bulk bag unloader, a funnel, a sack-emptying box or directly from the bag via a suction lance.

COHESIVE POWDER BLENDING
In Matcon Americas’ Matcon intermediate bulk container (IBC) blender, mixing takes place directly within the IBC. This means recipe changeovers are essentially instantaneous, as the blender itself has no product contact parts to clean. The blender achieves high overall equipment effectiveness rates, as filling, emptying and cleaning take place off-line. By utilizing a high-shear intensifier with the Matcon IBC blender, the range of blending capabilities is extended, providing efficient mixing and blending of cohesive powders and featuring the ability to directly add and disperse liquid content to the recipe batch.
PUMP AND BLENDER IN ONE
Fristam Pumps USA said placing its FSI shear pump after a mix tank reliably produces consistent product and eliminates the need for a shear blender and a transfer pump. When an FSI shear pump is installed after a mix tank, a product is blended thoroughly in a single pass. Due to its integrated impeller, the pump also transfers the blended product like a centrifugal pump, eliminating the need for both a blender and pump. Additionally, the pump reduces maintenance time and parts expense with its simple front-loading seal.
GEA GROUP said it has extensive experience in liquid/liquid and liquid/powder blending. Its scope of supply includes both standard and in-house custom-designed systems for a variety of applications. GEA can also supply the most appropriate process technology, unit or complete mixing solution. It offers solutions that are hygienic and multipurpose, including high-shear batch mixing, continuous inline blending and continuous inline mixing processing solutions. The company also supplies a wide range of liquid-handling option, from components to equipment and complete process lines.
POWERFUL IN-LINE CRUSHER
Franklin Miller Inc.’s Pipeline Delumper is a powerful in-line crusher that chops, destroys, disperses and suspends tough solids in fully enclosed pipe systems. This unit eliminates blockages, works the stream to free flow and prevents damage to pumps and other equipment. Franklin Miller said the crusher is suitable for wet, dry, pressure or gravity systems. It is ultra-compact and designed for easy installation. This fluid-tight pressure-rated unit has the full-throughput capacity of the pipe to which it is connected. It employs rugged impeller teeth passing through a heavy bar grating to reduce the size of the product. These teeth completely clear the slots of the bar grating and, at the same time, clean the entire pipe cross-section area. The machine is fabricated in carbon and stainless steel in 3-inch to 24-inch pipe sizes.
UNIT THAT COOKS, COOLS AND BLENDS
The 70N cooker-cooler from Chester-Jensen Co. Inc. is a batch mixing processor designed to cook, cool and super-blend all within the same vessel. Utilizing dual agitation with a fully insulated steam jacketed cone bottom, this unit is capable of producing uniform finished products. Sizes are available up to 1,000 gallons, and a 100-gallon loaner unit is available for a one-month free trial. Chester-Jensen said the cooker-cooler typically handles products such as cheese sauce, pastry and pie fillings, pudding and more.
Ampco Applied Products (AAP) said it introduced two new blending systems. The Shear-max inline mixer is extremely effective at dispersing and hydrating powders and is meant for single- or dual-stage high-shear mixing for liquids and semi-solids. The Jet-shear in-tank mixer is designed for the toughest applications. The Jet-shear will hydrate, dissolve, homogenize, disperse and emulsify products consistently and efficiently in food, chemical and pharmaceutical applications. Custom shaft lengths, varying motor styles and a variety of mounting options are available.
Admix’s DynaShear inline high-speed disperser has a powerful dual-stage rotor/stator design that ensures all ingredients are fully utilized rather than filtering them out due to inadequate conventional mixing. Installed on the outlet of a mix tank, a single pass of a product through the DynaShear unit instantly completes the desired mixing of stabilizers, gums, whey/plant proteins, sweeteners and milk/cocoa powders, Admix said. Smooth, completely uniform ice cream mix, flavored milks, coffee creamer and starters for cheese, yogurt, dip, buttermilk and sour cream can be transferred from the batch tank directly to the balance tank. Optimized finished textures can also be achieved by installing the unit just before the filler.
BLENDERS FOR DIFFERENT NEEDS
The Likwifier Division of Ensight Solutions said it offers high-shear, high-speed blenders used by dairy processors worldwide. The company has multiple designs and sizes to meet different blending needs: from small pilot plant to full production scale, including single and multiple impellers with blenders ranging from 10-gallon to 2,000-gallon capacity. Likwifier also offers controls, programming and other components to meet the application’s needs. An upgraded bolt on impeller housing is available in some models for easier access to impeller and maintenance.
