[0038] The motor 304 is driven, so that the motor 304 drives the driving gear 303 to rotate, and the driving gear 303 drives the driven gear 301 to rotate, so that the driven gear 301 drives the mixing cylinder 2 to rotate in the inside of the shell 1, and the arrangement of the rotatable mixing cylinder 2 can guarantee the effect of the mixing of the starch suspension and the catalyst, and the efficiency of discharging the supernatant from the inside of the mixing cylinder 2 is also high.

When the shielding plate 501 contacts with the inner wall of one side of the adjusting groove 502, the connecting disc 503 cannot rotate, which means that the shielding plate 501 no longer shields the permeable hole 401. The arrangement of the shielding plate 501 that can shield the permeable hole 401 ensures the sealing of the mixing cylinder 2 when the starch suspension and the catalyst react in the mixing cylinder 2, and only needs to rotate the shielding plate 501 when cleaning the supernatant.
