Application of laser particle size analyzer in flavored coffee

1. The influence of particle size distribution on coffee flavor

    Uniform dissolution and balanced flavor

The particle size distribution of coffee powder directly affects the contact efficiency between hot water and coffee particles. If the distribution is too wide, the fine particles will be over-dissolved (leading to a bitter taste), while the coarse particles will be under-dissolved (leading to a sour taste); a uniform particle size distribution can ensure that all particles have similar dissolution rates, achieving a pure and refreshing taste.

2. Technical advantages of laser particle size analyzer

High precision and wide measurement range

The laser particle size analyzer is based on the principle of light scattering and can detect particles ranging from nanometers to millimeters, covering the common particle size range of coffee powder (for example, D50 value is between 163–341 μm), and supports rapid automated measurement.

Dry test suitability

Coffee powder easily swells when exposed to water. Dry testing avoids sample agglomeration by dispersing gas (air pressure 0.05–0.2 MPa) to ensure data accuracy.

Special optical system design

Using forward and reverse Fourier combined with optical system and multi-directional scattered light detection technology, the distribution of coarse and fine particles, such as D10, D50, D90 and other key parameters, can be accurately analyzed at the same time.

3. Industry Applications and Quality Control

Research and development of coffee machines and grinding equipment

Manufacturers use laser particle size analyzers to optimize the design of grinding machines to ensure that the particle size distribution at different gears meets standards (such as uniformity error <5%), thereby improving product competitiveness.

Real-time monitoring and process improvement

Integrating online particle size detection into the production line can monitor grinding quality in real time and reduce batch differences, such as optimizing particle uniformity by adjusting cutterhead clearance or rotational speed.

Summarize

The laser particle size analyzer has become a core tool for improving coffee flavor by accurately controlling the particle size distribution of coffee powder. Its technical advantages are not only reflected in high-precision measurement, but also in providing a full-process solution for the coffee industry from research and development to production. In the future, with the development of intelligence and multi-technology, its application in flavor optimization will be more in-depth.This time, Winner2308A is recommended for customers to test flavored coffee samples.
