Smarter Particle Sizing, Better Refreshment! Malvern Launches New Accessories for Chocolate and Coffee Analysis

publication date: Dec 23, 2015
author/source: Malvern Instruments Ltd


Malvern Instruments have released new accessories for the Mastersizer3000 which optimize  the particle size analysis of chocolate and coffee.

The two new, innovative additions to the Mastersizer portfolio – Chocosizer and the Funnel Sample Feeder for the Aero S - enable faster analysis and make it easier to develop and apply the robust particle sizing methods that are essential to both industries.

Particle size directly impacts both the flavor and strength of coffee. Consistent production of the correct grade of coffee therefore relies heavily on the quick and reproducible measurement of coffee ground particle size and size distributions. Controlling the particle size of chocolate ensures desirable taste and texture, creating a similar requirement for routine particle sizing within the industry.

Used in combination, the Mastersizer 3000 and the new Funnel Sample Feeder for the Aero S dry powder disperser offer a superior alternative to traditional sieve analysis for the routine measurement of the particle size distribution of coffee samples. The new accessory is designed specifically for bulk measurements of coffee grounds within production and quality control and accurately, quickly and easily disperses coffee samples ranging up to 130 ml in volume, ahead of measurement. It speeds up and simplifies the process of introducing samples for analysis, decreasing the time required to obtain results. The state of the art Chocosizer kit from Malvern enables the highly efficient and reproducible measurement of chocolate samples, by streamlining the analytical workflow. To achieve accurate, representative particle size data chocolate must be dispersed within a suitable solvent. The Chocosizer kit includes an external ultrasonic probe, timer and liquid dispensers, enabling the efficient pre-dispersion of chocolate samples prior to measurement.
