Standard Compliant Fat Refinery Process Optimization
Various processes are applied during fat refining, such as raffination,  transesterification or fat hardening. Each workflow requires samples to be characterized after defined process steps. One of the most important techniques for this purpose is the melting point detection. METTLER TOLEDO’s FP83HT offers easy, reliable and automated determination of the fat melting point. Methods for thermal values of fat determination Although it is customary to speak of the melting points of fats, they really have no melting point in the proper sense of the word. Pure substances have a sharp melting point, i.e., the temperature of transition from the solid to the liquid state. Fats are invariably mixtures of mixed triglycerides and each individual triglyceride has its own melting point. Fats, therefore, have a melting range. A variety of methods exist for the determination of the melting point (mp) of fats. These include the Wileymp (AOCS Method Cc 2-38), open ...

Yellowness is Measured In-line with one Compact Sensor
In a modern brewery, more and more quality related parameters are measured directly in the process. Benefits of such real-time measurement data are better plant control and optimization of several process steps without time delay. Also, for quality documentation purposes and charge traceability charts, analytical in-line data are of paramount importance. Visual parameters such as beer brightness and beverage color are evaluated by the quality-conscious consumer even before he starts to drink, and can influence his purchase decision. Applications Beer filtration and filling The brightness of a beer – the absence of turbidity – is typically measured in EBC (European Brewery Convention) or ASBC (American Society of Brewing Chemists) units. In filtered beers the turbidity is typically smaller than 1 EBC, which equals 69 ASBC. Turbidity is directly measured in the outlet of a Kieselguhr or membrane filter, and in filling lines. In a dual scattering angle system both 90° ...

The Lower the Oxygen the Better the Beer
Oxygen in beer reduces shelf life and can affect flavor. Advanced optical measurement and sensor diagnostic technologies ensure you are keeping oxygen to a minimum, simply and dependably. Minimizing oxygen Oxygen in the brewing process is monitored because of its importance on the quality, taste and shelf life of the beer. After fermentation, beer is close to being oxygen free and maintaining this very low oxygen level is important for quality assurance. Therefore O2 uptake during the following separation, filtration, storage and filling processes has to be minimized. To reduce the risk of contamination, permanent and precise oxygen monitoring is required. Continuous measuring of oxygen concentration places high demands on an in-line O2 system. Such equipment must be easy to install and operate, require minimal maintenance and, most importantly, always measure accurately. Intelligent optical sensor The latest development in optical oxygen sensors, the InPro 6970i from METTLER TOLEDO, delivers outstanding ...
