Brabender MT-CA: Fast Moisture Data for Accurate Green Coffee Roasting with Automated Oven Drying
The Brabender MT-CA moisture analyzer determines green coffee moisture by oven drying and loss in weight. At PROBAT, it supports incoming goods inspection, NIR reference measurements, recipe adjustment, higher sample throughput, reduced handling errors, and digital result management.
Green coffee moisture content is a critical quality parameter because it affects storage stability, quality risks during transport, and roasting behavior. PROBAT is a global leader in processing technology, providing innovative machines and plant solutions for coffee, cocoa, chocolate, and other food industries. With over 155 years of experience, the company delivers efficient, high quality, and sustainable production systems worldwide[3].
PROBAT states that green coffee varies by origin and type, and that moisture levels above 13% can increase the risk of mold and other quality problems during storage. For that reason, moisture must be checked when goods are delivered so recipe parameters can be adjusted where necessary. PROBAT uses near-infrared spectroscopy for fast screening, but it requires calibration against a direct reference method. For this purpose, PROBAT uses the Brabender MT-CA moisture analyzer, which applies the oven drying method and determines moisture from the sample’s loss in weight. The application report below describes how the MT-CA is used for green coffee moisture analysis, outlines a typical method for coffee, and highlights the practical benefits for PROBAT, including faster workflows, reduced manual handling, support for up to ten samples, and digital result management with MetaBridge.
