Save costs on your coffee production with TEWS Microwave Technology

Efficient moisture measurement is vital in coffee production, ensuring quality, compliance, and cost savings from the arrival of green coffee beans to the roasting stage. With TEWS microwave technology, producers gain access to advanced, fast, and precise moisture analysis, improving production efficiency and reducing waste.

Moisture Measurement in Green Coffee Beans

Green coffee beans typically arrive with a moisture content of 10% to 13%, which must be closely monitored to prevent spoilage and ensure high-quality storage. TEWS microwave technology enables accurate moisture measurement through three methods:

Laboratory Testing: Offers controlled, high-precision results for quality assurance.
At-Line Measurement: Provides immediate moisture insights directly next to production processes.
In-Line Monitoring: Delivers real-time, continuous data integrated into the production line.

Accurate measurement at this stage preserves bean quality, reduces waste, and optimizes storage conditions, making it an essential step in coffee production.

Moisture Management During Coffee Roasting

Roasting transforms green beans, developing the rich aroma and flavor of coffee through the Maillard reaction at temperatures around 230 °C. During this process, moisture is significantly reduced. After roasting, producers often apply extinguishing water to halt the process at the desired roast level.

TEWS microwave technology ensures precise moisture control during and after roasting by:

Measuring Moisture in Roasted Beans
Ensuring compliance with the legal moisture limit of 5%, TEWS provides immediate, accurate measurements during the cooling phase to guarantee quality.
Optimizing Extinguishing Water Use
Adjust the water application to achieve the perfect balance, preventing overuse and maintaining the coffee’s desired texture and flavor profile.

Advantages of TEWS Microwave Technology for Coffee Producers

Cost Efficiency: Minimize waste and avoid unnecessary use of extinguishing water.
Regulatory Compliance: Guarantee moisture levels meet legal standards.
Enhanced Product Quality: Maintain the desired aroma, flavor, and texture through optimized moisture management.
Real-Time Results: Gain actionable insights with fast and reliable measurements.
Versatility: Suitable for green beans, roasted coffee, and every stage in between.
