Application of laser particle size analyzer in coffee field

Particle morphology is an important parameter affecting food properties. At present, coffee has become a fashion. In order to ensure that coffee can obtain the best taste, professional coffee grinders will have more stringent requirements for the coffee particle size, and the particle size of the ground coffee particles will be more stringent and precise. Standardized control. In the past, the screening method was traditionally used, but it has been replaced by the laser particle size method. This is mainly because the laser particle size method is faster, has good reproducibility, saves labor costs, and is more economical.

For the measurement of coffee particles, the dry method is generally used because coffee particles will swell in water. After selecting the appropriate dispersion gas pressure, the particle size of the coffee beans after grinding can be accurately characterized. The test results include the average particle size, medium diameter value, etc. of the coffee sample, thereby ensuring that the coffee quality meets the standards and consumption request.

We recommend the dry laser particle sizer Winner3008 to test coffee powder particle size distribution.
