Abstract

This invention proposes a clean intermediate bearing structure for large fermenters, comprising a matching coupling structure, multiple support components, and sealing components corresponding to the coupling structure and support components. The coupling structure includes an intermediate bearing structure and a bushing. The bushing is vertically positioned in the middle of the intermediate bearing structure. The intermediate bearing structure is equipped with multiple adjustable clamping mechanisms that abut against and fit against the bushing. The support components are arranged circumferentially on the intermediate bearing structure, with one end connected to the fermenter wall. The clean intermediate bearing structure for large fermenters described in this invention has advantages such as structural stability, excellent sealing effect, and applicability to fermenters of different diameters. This design solves the current problem of lacking a clean design for hygienic intermediate bearings in large fermenters.
