In order to study a swelling process of beans, we measured volume and weight of seven kinds of beans using a hand-made volumenometer reported in the previous paper.
As the results, it became clear that both weight and volume of beans were saturated after swelling for 8 hours, and weight of beans increased by two times that of its original, and volume showed a value 2-3 times as much.
We estimated change of net volume, net weight and normalized density of each beans according to 24 hours' swelling, and discussed the swelling mechanism of beans.
