The bottom outlet of the shell 1 is equipped with a discharge ball valve 10, and the top of the shell 1 (elliptical head 13) is equipped with a feed port and a cleaning port 14.
[0024] The ribbon stirring device is installed inside the housing 1 and includes a stirring shaft 21 and a ribbon blade 22. The bottom end of the ribbon blade 22 is fixed to the bottom end of the stirring shaft 21. The middle part of the ribbon blade 22 is connected to the stirring shaft 21 through a crossbeam 23. The top end of the ribbon blade 22 is connected to the stirring shaft 21 through an arc-shaped connecting beam 24.
[0025] Specifically, in this embodiment, one end of the crossbeam 23 is connected to the stirring shaft 21, and the other end is connected to the middle of the spiral blade 22; the top end of the arc-shaped connecting beam 24 is connected to the top end of the spiral blade 22, and the bottom end is connected to the stirring shaft 21; and the connection end a between the crossbeam 23 and the stirring shaft 21 is located below the connection end b between the arc-shaped connecting beam 24 and the stirring shaft 21. The bottom end of the stirring shaft 21 is located inside the lower conical cylinder 12 and is positioned near the bottom discharge port.
[0026] The stirring drive device includes a stirring motor 31, a reducer 32, and a reducer mounting bracket 33.
