★ Selects large-grained, good-quality seed rice.



Germination comparison according to seed size.

When large and small seeds sorted according to grain size are allowed to germinate,significant differences appear.

Small grains× Germination occurs but plants are subject to mold and disease.

Large grains○ Garmination and rooting are robust and growth is excellent.

Design allows for easy disassembly and cleaning.

Parts can be removed easily, making it easy to clean the unit in preparation for another variety of rice seed.
