Washing, dehydrating and drying of germ（9）

The germ flowing out from the top of the primary germ cyclone is washed through a multi-stage gravity curved sieve (water content of 75%) to thoroughly wash off the starch attached to the germ and enter the germ screw extrusion dehydrator. The moisture content of the dehydrated wet germ is approximately 55%, and is then dried through a tube bundle dryer, at which time the moisture content of the germ is reduced to 5%.
