Inline Process Refractometers for Brewers

Inline Process Refractometers for Brewers

Beer brewing and branding are all about consistency. Process monitoring is thus vital. With Electron Machine inline refractometers, you'll have less waste, use less energy, spend less money, and achieve better beer. 


While some breweries still use manual sampling and lab analysis, the trend is adapting inline monitoring and automation.  Laboratory analysis is part of R&D. It reveals how different substances or methods affect qualities like flavor and fragrance. Laboratory analysis is vital in research as it provides an understanding of chemistry. However, the utility of sampling and analysis can be limited in manufacturing due to costs and delays when the lab findings indicate the issue. Slow sample timing results in possible lost production and waste. Similarly, because the sample is a snapshot of the process, it cannot provide feedback control, timely alarms, or indicate trends. 


The angle of refraction of light in the process medium determines the refractive index (RI), which the inline refractometer computes important process variables continually. Electron Machine inline process refractometers will calibrate to Brix, Gravity, Density, or Plato and withstand CIP/SIP cleaning and rinsing operations. 


Process refractometers have a quick response time which provides critical information in all stages of beer production. Examples of applications for inline refractometers that arise throughout the brewing process:


  • Grain mashing - Refractometers measure mash concentration in the output pipe water.
  • Lautering - While the spray water rinses the grains, it completes the sugar extraction process and produces clear wort. The refractometer continuously measures this concentration to determine the rinsing breakpoint, saving water and electricity.
  • Wort boiling - Refractometer installed directly on the wort boiler continuously measures wort strength / specific gravity, allowing the brewer to determine the required concentration.
  • Rousing or Swirling - Solid particles are removed from the bitter wort in a vortex. The vortex causes the leftover particles to thicken and form sludge. The solids removal uses refractometers placed before or after the vortex for a clear bitter wort for the next phase.
  • Cooldown - A heat exchanger cools the wort, recovering some of the energy needed to boil it. Refractometers are affixed to the cooler's outflow to ensure the bitter wort has the proper level of dissolved solids.
  • Fermentation - Yeast ferments wort to produce CO2 and alcohol. The specific gravity (or relative density) of the fermented liquor is determined using refractometers. The alcohol concentration directly correlates between the initial wort density and current density, so the refractometer can closely monitor fermentation. It gives brewers real-time information into the process, allowing them to predict fermentation completion.
  • Filtration and Aging - The beer is rested after fermentation to settle the used yeast. But several filtration procedures are used to refine the beer as the last chance to impact beer quality. Refractometers assist in measuring bitterness, flavor, fragrance, foam stability, clarity, alcohol, and gas percentage.
  • Filling and CIP (Clean-in-Place) - With the refractometer, you can quickly swap between items or batches and easily detect production from cleaning products. 


In summary, refractometers assist brewers in optimizing processes, decreasing waste, saving energy, and maintaining consistency, and making great beer.

Ensure Juice and Beverage Quality and Consistency with Inline Process Refractometers

Inline Process Refractometers

The inline Brix analysis of juice and beverages offers automated, exacting process control and quality monitoring by continuously measuring and monitoring the quality and consistency of each component with high precision and controls the dosage during the blending of the products. 

Inline refractometers also assure that the correct product is in process, particularly when blending and filling a variety of juices, syrups, nectars, soft drinks, and other beverages on the same line.

Syrups, juice concentrates, and other ingredients are frequently blended with water according to specific formulas, then held in stacking tanks, and lastly poured into product-specific bottles or containers in the beverage industry. 

The entire product batch may be defective if a primary component, such as a juice concentrate, does not precisely meet the specifications or if the blending process itself is incorrect due to incorrect valve switching.  It's also possible that the faulty product goes to packaging due to an improper phase transition. If this is discovered only during final quality control, the entire production batch could be at risk. 

With an inline refractometer, each process stage gets precisely managed by measuring the dissolved sugar in the liquid. In comparison, manual Brix control sampling with a hand refractometer is labor-intensive and open to operator error. Furthermore, any mistake can only be detected after the fact, affecting the production quantity between two samples or a complete filling batch, and then discarded. The inline process refractometer is integrated directly into the process with high accuracy and continuously, allowing the definition and differentiation of each component or product.

Applying Refractometers in Starch/Sizing Liquid for Paper Production

Refractometers in Starch/Sizing Liquid

Cooked starch or sizing liquid is used in paper sizing to reduce the paper's tendency to absorb liquid when dried. The reduction in fluid allows inks and paints to better remain on the surface and helps create stabilized sizing conditions, allowing a consistent paper quality across the different paper grades.

The MPR E-Scan gives paper companies the ability to accurately control the sizing/cooked starch by detecting changes in the concentration of the cooked starch. This precise measurement effectively controls the freshwater flow to the size press/starch circulation system, reducing excessive water usage. Combining the measurement with data-analysis tools, a company can monitor inefficiencies in the starch/sizing line and evaluate the dilution levels. The result is improvements in starch/sizing operation's efficiency and an overall reduction in water, reducing the overall time needed to meet target dilution. By providing a near-instant reading of starch concentration and temperature, the instrument removes the reliance on offline testing. This application should also include automatic prism wash using heated high-pressure water and matching the wash water temperature to the process, reducing any thermal shock and sensor.
