ABOUT BROOKFIELD AMETEK

Brookfield, a business unit of AMETEK Inc, is the world leader in viscosity measurement and control of liquids and semi-solids.  Products include AST 100 Process Viscometer for continuous in-line viscosity measurement, DV2T Touch Screen with temperature measurement, DV3T Rheometer for measuring yield stress and viscosity, RST Controlled Stress for comprehensive rheological measurements, CT3 Texture Analyzer for compression/tension testing to assess firmness, springiness and chewiness and PFT Powder Flow Tester to evaluate flow behavior from converging hoppers.  Markets served in addition to foods and beverages include cosmetics, pharmaceuticals, oil & gas drilling fluids, personal care products, adhesives, printing inks & coatings, chemicals, packaging materials, plastics, construction materials, and asphalt.

Viscosity Measurement and Control

The ability to characterize a material’s viscosity behavior gives food manufacturers an important handle on processing, such as power requirements for pumps and mixers or fill line productivity with cans, bottles, tubes, etc.  Knowledge of a material’s rheological characteristics is valuable in predicting customer acceptance for behaviors like pourability, dipping, coating, or mouth feel when eating the product.  The correlation between rheological measurements and other product characteristics often makes viscosity the key parameter for detecting changes in product quality and stability.

Ease of use, flexibility, reliable performance and quality of service have made Brookfield Viscometers/Rheometers favorites all over the world. They are accurate within ±1.0% of the viscosity range in use and have repeatability within ±0.2%. Test results can be duplicated anywhere in the world using a Brookfield instrument with the same torque range.

Brookfield Process Viscometers are used in pipes and tanks to provide real-time information on viscosity behavior which can in turn be used for process control.

Texture Analysis

Texture analysis quantifies mechanical properties of food products which relate to sensory properties when handled, tasted and eaten by humans and animals.  The fundamental approach is a two-cycle texture profile analysis test. Texture analyzers perform this test by applying controlled deformation to the product and recording the amount of force and work required to accomplish the deformation.  Biting, chewing and swallowing are examples of actions that a Texture Analyzer can mimic. 

The Brookfield CT3 Texture Analyzer performs uni-axial compression and tension testing in combination with a selection of probes, grips and fixtures to test a wide variety of foods. Most tests desire to imitate conditions imposed on these products during manufacture, handling, and consumption or use. Characterizing the physical properties of your food products in such an analytical manner provides “real life” insight to flow behavior and can be invaluable in producing consistent, high quality food products while controlling costs.

Powder Flow Analysis

Unlike liquids, powders have structure due to internal friction and cohesion between particles, which allows them to form piles with angles relative to the surface on which they are placed.  Powders do not change flow behavior when subjected to variable shear rates, whereas most liquids do.  Increasing pressure or compaction affects the strength of a powder (i.e., increases the resistance to flow).  The consequence of subjecting a powder to a compressive force is that the powder will flow less easily.  The relationship between the compressive stress applied to consolidate the powder and the strength it obtains is called “Flow Function”.

Particulate materials constitute a large group of solids that can range in size from sub micron particles to large rocks and minerals.  Brookfield’s Powder Flow Tester measures the flow behavior of bulk solid materials that have a maximum particle size of 2mm.  At least 90% of the sample should consist of particles less than 1mm in diameter.  In many instances, powders with larger particles can still be characterized effectively by sieving the material at 1mm and testing the fines which generally control the flow properties of a material.

Viscosity Testing Services:  Brookfield’s state-of-the-art laboratory offers a variety of viscosity testing services capable of measuring Newtonian and non-Newtonian fluids using a wide range of spindle geometries. Detailed test results include equipment and measurement system description, viscosity data that includes appropriate tables and graphs, and any recommendations pertinent to your specific material and associated method.

Methodology Consulting Service:  Brookfield engineering consultants come to your facility to review and recommend appropriate test methods for your materials. Our staff will work with you to define acceptable viscosity behavior taking into consideration relevant shear rates, shear stresses, temperature profiles, and time sensitivity issues.

Calibration & Certification:  The staff of Brookfield's Repair Department will inspect your instrument for wear, clean, adjust and lubricate the internal mechanisms, replace parts of the sensing system or as needed, and check your spindles for straightness. We calibrate and certify in writing that your instrument is operating within proper Brookfield specifications.

On-site Repair, Calibration & Certification:  Brookfield technicians keep customers up and running when you can’t afford to stop production and return your instruments to Brookfield for repair. Brookfield service technicians will visit your facility and make sure that your instruments are in top running order.
