This invention provides a slow-release feed device for marine aquaculture, relating to the field of marine aquaculture technology. It includes a rotating drum, a drum cover, and a fixed shaft. A rotating impeller is mounted on the rotating drum, which is connected to the drum cover to form a cylindrical space. The fixed shaft passes through the central axis of the rotating drum and drum cover and is rotatably connected to them. A cake holder, a feed cake, and a cake brush are installed within the cylindrical space. The cake holder is fixedly connected to the fixed shaft, and the feed cake is mounted and fixed on the cake holder. The cake brush rotates synchronously with the rotating drum, brushing the surface of the feed cake to accelerate slow release. Utilizing ocean currents or the up-and-down movement of seawater, the rotating impeller drives the rotating drum to rotate, which in turn drives the cake brush to continuously brush the slow-release flocculated layer formed on the surface of the feed cake. This effectively accelerates the diffusion and release of feed particles, solving the problem of excessively long natural slow-release time for feed cakes and their inability to pass through a 150-mesh or finer silk sieve, thus meeting the needs of aquaculture such as oyster farming.

This application discloses a filtering device for processing vegetable fat butter, relating to the field of butter processing technology. It includes a support cylinder with a rotating heating mechanism at its top. The device utilizes a drive column to drive a connecting box to rotate horizontally, thereby causing a rotating drum to rotate horizontally around the drive column.
