  • Preferences and requirements for batch mixers used in the food industry

    In the food industry many end products are mixtures of solid substances. Examples of such products are dessert mixtures, sugar blends, instant drinks, dried soups and sauces, dietetic foods and spice mixtures. The great variety of constituents, such as milk powder, cream powder, sugar, cocoa, flour, vegetables, fungi, spices, fats (liquid and solid), places great demands on the batch ...

  • In Situ Rheological Monitoring of Viscous Non-Newtonian Fluids using a Helical Ribbon Agitator

    Mechanically degraded food fluids were modelled as Power law fluids in a pilot scale (42 l) helical ribbon agitation vessel. Effective rheological representative flow curves determined from speed/torque data proved comparable to off-line laboratory rheometer measured data. Modelling effective viscosity as a Power law function gave effective consistency coefficient Keff which correlated strongly ...

  • Pharmaceutical glass manufacturer blends 120 batches/day of abrasive ingredients

    The manufacture of high-quality pharmaceutical glass is an exacting business that calls for careful control at all stages of the process in order to obtain the desired properties in the final product. Those properties vary, depending on what the glass is to be used for, so the initial step - the precise measurement and thorough mixing of multiple ingredients - is critical to the rest of the ...

  • Continuous mixing systems for the production of pharmaceutical tablets and granulates

    The Process Analytical Technology initiative demands the implementation of in-process monitoring systems and controls along with the mixing process. Gericke has developed continuous mixing and metering systems that meet the stipulated accuracy and the highest hygienic requirements. Own testing and model calculations demonstrate that their efficiency is determined not only by ...

  • Impact of heating method on the flocculation process using thermosensitive polymer

     Flocculation process based on water soluble polymers as flocculating agents is still intensively researched nowadays, despite the introduction of these materials about fifty years ago. There is a need to gain the full control of this process in order to obtain high efficiency and strictly define products. For that purpose new solutions are proposed like stimuli-responsive macromolecules. In ...

  • Rapid blending of nutraceuticals in a restricted space

    Although vitamins and minerals have long been a mainstay in health maintenance, a new category of health maintenance products has created an entirely new market over the last two decades. The term "nutraceutical" was first defined in 1989 by Stephen DeFelice, M.D. as "... food, or parts of a food, that provide medical or health benefits, including the prevention and treatment of disease." Since ...

  • Application notes - viscosity measurement

    Most laboratory viscometers employ the well-known principle of rotational viscometers to measure viscosity by sensing the torque required to rotate a spindle at a constant speed while it is immersed in the sample fluid. This is because the torque, generally measured using the reaction torque on the motor, is proportional to the viscous drag on the immersed spindle and thus the viscosity of the ...

  • San Jose Water Company Solves Chloramine Residual Problem with the Process Solutions, Inc. Monoclor Chloramine Management System

    Located on the southern edge of California’s ever-expanding Silicon Valley, the San Jose Water Company treats and distributes water to over 1 million people. Founded in 1866, the investor-owned public utility has built a reputation for being focused on customer service and has been an early adopter of new treatment Technologies. Like many water utilities, San Jose Water has had to adapt to ...

  • Cavitation Reactors

    By combining the developments in acoustics, hydrodynamics and chemical kinetics, a new promising device is entering the market: the cavitation reactors, used for processing of suspensions, emulsions and for intensification of chemical processes in solutions. These devices are can be used either separately (in laboratory test-benches) or in industrial mixing processes. In today’s market, two ...

    Environmental-restoration product manufacturer requires fast, uniform, gentle blending of powdered microbes, enzymes and nutrients The microbial formulations that United-Tech, Inc. produces are used to break down or detoxify a broad array of complex, often-toxic organic compounds, greasy spills and other contaminants in a variety of ...

  • WEFTEC’ 2013 Lagoon wastewater treatment using Innovative bioaugmentation technology case study

    Introduction and Problem Statement Lagoon wastewater treatment systems employ a combination of physical, chemical, and biological processes to treat wastewater. Lagoon wastewater treatment systems are simple, natural, energy efficient, and one of the most cost effective treatment options, especially for small and rural communities. Lagoon systems are easy to operate, require lower ...

  • Field-scale cleanup of atrazine and cyanazine contaminated soil with a combined chemical-biological approach

    A former agrichemical dealership in western Nebraska was suspected of having contaminated soil. Our objective was to characterize and remediate the contaminated site by a combined chemical-biological approach. This was accomplished by creating contour maps of the on-site contamination, placing the top 60 cm of contaminated soil in windrows and mixing with a mechanical high-speed mixer. ...

  • Field-scale cleanup of atrazine and cyanazine contaminated soil with a combined chemical-biological approach

    Received for publication August 12, 2008. A former agrichemical dealership in western Nebraska was suspected of having contaminated soil. Our objective was to characterize and remediate the contaminated site by a combined chemical-biological approach. This was accomplished by creating contour maps of the on-site contamination, placing the top 60 cm of contaminated soil in windrows and mixing with ...

  • Bringing powdered metal blending in-house, rotary-style

    When processing powdered metal compounds for products such as gyro rotors, flywheels, counterbalances, boring bars and grinding quills, the proportion of powdered metal ingredients must be precise, and the distribution of those ingredients 100 percent uniform. Mi-Tech Metals, Indianapolis, IN, has been manufacturing products from high-density tungsten-based alloys for more than 26 years, during ...

  • Water treatment helping cars stay cool - automotive industry: Orlando, Florida

    A manufacturer of air-conditioning line connectors for automobiles was required by the city to meet new sewer discharge standards. They had been using a system of gravity separation which did not address suspended solids or soluble metals. Their wastewater is generated from 3 sources; mop water, parts deburring and polishing, and floor scrubber water. They generate approximately 6,000 gpd of ...
