Method for grading of potatoes entails transmitting mass and volume values for each potato to processing unit from which density value is obtained to determine density dependent starch content

摘要

The method for the grading of a quantity of potatoes entails separating them into individual potatoes, determining a mass value for each by a weighing device (4) and determining a volume value by a volume measuring device (10). The mass and volume values are transmitted to a processing unit (13) from which a density value is obtained and from this value is derived density dependent starch content and a grading signal for the individual potato. The grading signal is transmitted to a sorting unit (11,12) which is then controlled to grade potatoes by starch content. An independent claim is included for a device for the grading of a quantity of potatoes according to starch content.
