Streamlining quality control in the food industry


In the dynamic landscape of the food industry, ensuring quality control is paramount. Catering to the varied requirements of food manufacturers, Anton Paar’s ViscoQC 300 rotational viscometer stands out as a revolutionary solution, providing an advanced approach to viscosity testing with sophisticated mathematical models, as well as unique features for a streamlined quality control process.


With the V-Curve software activated on the stand-alone ViscoQC 300, the full potential of the viscometer is unleashed. Going beyond standard test methods such as speed scans or time- and torque-dependent measurements, the user can perform more refined tests based on mathematical models like the Thixotropic Breakdown Coefficient, the Casson, Herschel-Bulkley and Bingham models, and many more. This provides extra information about the product’s plastic viscosity, yield stress, consistency and flow index. These parameters influence the products’ texture, coating ability, and flow behaviour during processing. For instance, when chocolate is being tempered, moulded or coated onto confections, its plastic viscosity affects how smoothly it spreads, how well it adheres to surfaces, and how it sets once cooled. The large 7” touch display and the graphics function make operating and analysing the results a pleasure; PC software becomes obsolete.


When analysing the viscosity of non-flowing substances like jams or spreads using standard or cylindrical spindles on a rotational viscometer,


an air channel can form within the sample, causing inaccurate readings because the spindle loses contact with the substance. To address this, the motorised Heli-Plus attachment with T-bar spindles is employed. As the spindle rotates, the viscometer moves downward through the sample in a helical pattern, ensuring continuous contact with fresh material.


At the core of Anton Paar’s ViscoQC 300 is its capability to standardise testing methods. This is achieved through a cutting-edge feature allowing the start, immersion, and reversing positions of the measuring spindle to be digitally defined and memorised for up to 60 different self-created methods. Recognising that different products may require specific testing conditions, Heli-Plus allows users to customise and store method-specific settings. This ensures that each test adheres to predefined criteria, as the Heli-Plus is fully controlled by the viscometer. The outcome is a unified quality control process that reduces variations, improves reliability, and ultimately contributes to the production of consistently high-quality products.

Flow sensing challenges in food and beverage production


Titan Enterprises offers a range of high-performance flowmeters in food grade materials where both food hygiene and precision flow measurement are required.


“The physical properties of the liquids themselves lend additional complexities to the choice of flow measuring equipment,” says Neil Hannay, Senior Development Engineer at Titan Enterprises. “Consideration of whether the liquid is viscous, volatile, corrosive, flammable, or contaminated with particles, for example, or needs to be maintained at a high temperature, are key factors in deciding a suitable flow meter.”


Flow monitoring of high viscosity liquids, such as cooking oils, sauces and syrups (e.g. syrup injections in beverage lines) require devices such as Titan’s oval gear flowmeters, which provide highly accurate flow measurement. Unlike other flowmeters, measurement accuracy of oval gear flowmeters improves as the liquid viscosity increases, from a nominal 1% to around 0.1% of flow rate at higher viscosities.


Whereas for low viscosity liquids such as water, beer, wine and spirits, Titan’s NSF-approved 800-series and beverage flowmeters provide a low- cost drink dispensing solution. Designed to give high performance over 6 flow ranges from 0.05 to 15 l/min, these devices have totally non-metallic


NSF-approved wetted components making them ideally suited for applications where both food hygiene and precision flow measurement are required.


In processes where ingredients need to be maintained at high temperatures – chocolate for example – a flowmeter designed for applications requiring precise flow measurement at elevated temperatures would be needed. Capable of operating up to 110°C, Titan’s inline non-invasive Atrato® ultrasonic flowmeter is largely immune from viscosity and offers excellent turndown and repeatability.


Titan Enterprises offers a range of oval gear flowmeters in food grade materials for viscous products such as sauces, oils and syrups, as well as NSF-approved mini-turbine flowmeters for drink dispensing. As an experienced OEM supplier, Titan develop customised flow meters for specific customer applications within the food and beverage industry.
