Measuring the moisture content of seeds is a crucial step in the oil pressing process. Seeds with too high moisture content can disrupt the entire process, significantly reduce pressing efficiency, and in extreme cases, completely block it.
Excessively moist seeds can also lead to mold and fungus growth, which accelerates oil oxidation. This process is the main cause of oil spoilage, resulting in unpleasant taste and smell, as well as loss of nutritional value.
The Dramiński GMM mini II Moisture Meter is the most popular model from this manufacturer. It is compact, modern, and an essential tool for any farm. It allows you to quickly and accurately check seed moisture directly in the field or storage location. With its built-in USB port, updating calibration data and software is fast and simple. Now, without sending the meter to a service center, you can enjoy the latest version even after many years.
The GMM mini II version is specifically calibrated for oilseeds, making moisture measurement for seeds intended for pressing hassle-free.
Moisture measurement for 14 common oilseeds:
The meter measures whole seeds using a capacitive method, with easy sample filling via the included dispenser. The large, clear graphic LED display shows:
Full seed type name
Moisture content in %
Average reading
Seed temperature
A digital temperature sensor in the measuring chamber ensures highly accurate readings.
The durable ABS plastic dispenser allows precise measurement of the correct sample volume.
