Coffee Application Note

Are you ready to improve your coffee roasting precision with real-time feedback?

Experience unmatched precision in optimizing your roasting process with our advanced VIS/NIR spectrometer technology for moisture and color during roasting coffee beans. Powered by tec5USA, our multimodal spectrometer covering the visible and near infrared (NIR) wavelengths of light combined with a Diffuse Reflection Probe (DRP), effectively captures the important 400 to 1700 nm (nanometer) wavelength range. This setup makes real-time measurements easier by placing the probe on a sight glass in the roaster ensuring accurate illumination and detection. Notably, our technology provides precise moisture and color measurements to determine the degree of roasting in milliseconds.

Can tec5USA analytical technology be integrated into existing roasters?

Our spectrometer system with DRP sight glass seamlessly integrates into your current roaster. The DRP is attached to the sight glass into the roaster to measure bean quality in real-time. Integration with your roasting control system enables real-time utilization of moisture and color data for automated temperature and air flow control during roasting. Informed by the signal from each spectrum, optimal roasting can be executed. tec5USA supports various communication protocols, including Modbus, Profibus, Ethernet I/P, OPC, Digital and Analog I/O, 4-20mA, to ensure smooth connectivity and integration of the spectrometer software into your automation environment.

Benefits of Real-Time Moisture & Color During Coffee Roasting:

Imagine the advantages of having real-time moisture and color analysis during coffee roasting. Our VIS/NIR spectrometer technology offers significant economic benefits:

  • Precision Roasting: With accurate moisture and color measurements in real time, beans can be roasted more precisely based on their incoming moisture content. Depending on harvest and storage conditions, initial moisture content can vary significantly and impact the temperature profile of a roast. This ensures every roast has the ideal flavor and premium quality.
  • Optimal Temperature: Real-time moisture and color analysis enables the creation of specific roasting temperature profiles. This allows for tailored roasting curves and adjustment to each batch of beans and targets, catering to various customer preferences.
  • Reduced Waste: By accurately measuring initial moisture, the likelihood of wasted batches is minimized. This reduces waste and increases the yield of premium quality beans.
  • Enhanced Efficiency: Real-time data driven roasting control streamlines the entire process, reducing labor costs and operational inefficiencies. Market Demand Alignment: Real-time moisture and color analysis ensures that your products exceed expectations for every lot of optimally roasted beans.

Experience the potential of VIS/NIR analysis to revolutionize your coffee roasting processes. Our advanced technology brings accuracy, reliability, efficiency, and economic benefits to your operations. Ready to explore the possibilities? Reach out to us today for an in-depth discussion!

    Raman spectroscopy is a technique which is used for several markets. These industries include Oil and Gas, Pharmacology, Biotechnology, Petrochemistry and many others. Due to the high selectivity of Raman spectroscopy, it is a powerful tool for many applications including, hydrocarbon analysis, bioreactor protein monitoring, crystallization monitoring, API concentration, polymer identification, surfactant analysis, natural gas components and several others....

    Typical applications include white light interference for thin film analysis, UV absorption of proteins for quantitative analysis, colorimetry, impurity detection in water, cleaning validation for API manufacturing, polymerization inhibitor monitoring, electroplating bath monitoring....

    NIR spectroscopy is utilized across a variety of industries for qualitative and quantitative product analysis. Typical industries include Chemistry, Pharmacology, Food Feed & Beverage, Agriculture, and others. NIR spectroscopy is well suited for species containing C-H, N-H & O-H bonds, making it a wide-range technology for a variety of applications such as moisture, fat, oil, alcohol, APIs, polymers, etc....

    Spectroscopy is the study of the interaction of light with matter. Light covers a broad range of the electromagnetic spectrum from high energy ultra violet (UV) photons to the near infrared (NIR), with the visible spectrum that we can see being in between. These different portions of the spectrum are important because they interact with matter in different ways. In the UV, these photons have high energy and therefore can induce electronic transitions, while the NIR photons can cause molecules to vibrate at unique frequencies. The way that we measure where compounds absorb light is by taking a spectrum, which is a graph showing the transmission of light as a function of the wavelength. All compounds have a unique absorption spectrum which can be used to identify the chemical composition of samples....

    The spectroscopic methodology is determined by which parameters are important to monitor during a process. For example, if you want to monitor protein concentration in a bioreactor, in which the biosynthesis takes place in an aqueous medium, then you likely would want to use Raman spectroscopy for the application, as water does not contribute to the Raman signal. Alternatively, if moisture content is important, water has very strong absorption in the NIR due to several vibrational and combination modes that can be monitored; water is transparent in the UV and visible spectral region. Understanding which chemical is important as there could be various factors that influence the choice of methodology....
