Analysis of Moisture, Degree of Roast and Caffeine in Coffee Beans and Powder

For companies handling and processing coffee beans it's important to be able to quickly and accurately determine key characteristics such as moisture, color/degree of roast and caffeine.

Perten Instruments has extensive experience from coffee applications and some of the most well-known companies use our instruments.

Purchasing  beans

When purchasing coffee beans, moisture content is critical. The AM 5200 Moisture Meter determines moisture in whole beans in just 10 seconds. It uses UGMA technology developed by the US Department of Agriculture and offers superior accuracy. It's easy to use and confidently operated by non-technical staff. It's rugged and can be placed in many different environments.

Bean Roasting and Instant Coffee Production

For producers of roasted coffee and instant coffee NIR (infrared spectroscopy) instruments offer huge benefits. NIR instruments can determine moisture in beans as well as in ground coffee and coffee powder. They can also determine color/degree of roast and caffeine. Being able to determine these parameters instantaneously provides great opportunities for savings and the investment is often paid back in a few months.

The DA 7250 At-line/Lab NIR analyses a sample in only 6 seconds and determines multiple parameters simultaneously. It readily analyzes whole beans as well as ground beans and coffee powder. It's rugged and easy to use, which means it can be placed on the factory floor as well as in a lab. Read more about the DA 7250.

The DA 7300 In-line NIR offers real-time measurements in your process. You can use it for continuous measurement of moisture, color/degree of roast and caffeine in beans after the roaster, to control the roasting process and verify quality of the finished product. It's also used for continuous measurement of moisture and caffeine in freeze-dried coffee. Read more about the DA 7300.
