Simple Coffee Moisture Meter Developed

The coffee moisture meter developed by PhilMech engineers in collaboration with a local electronic company.

A research team led by Engr. Arlene C. Joaquin of PhilMech has developed a prototype of a simple, inexpensive yet accurate coffee moisture meter in partnership with a local electronic company. This was announced by PCAARRD which funded the research. PCAARRD is the Philippine Council for Agriculture, Aquatic and Natural Resources Research and Development, an agency of the Department of Science and Technology.

The prototype measures the moisture content of green coffee beans and coffee parchment.It has been observed to make accurate measurement in Arabica coffee, Liberica (barako) and Robusta.

Drying coffee beans to the right moisture content is important. If the moisture content is higher than 12 percent (wet basis), the beans can deteriorate due to bacteria, mold and yeast. On the other hand, if the moisture content is below 9 percent, the beans will shrink and become distorted, making them appear low-quality beans. (Press Release)
