This utility model relates to the technical field of beverage extraction equipment, specifically disclosing a pecan beverage extraction device with homogenization assistance. The device includes a vessel body, which is the main equipment for pecan beverage extraction. The upper cover of the vessel body is penetrated by the output end of a drive motor, which is connected to a stirring rod. The bottom end of the stirring rod is rotatably connected to the top end of a support frame, and the bottom end of the support frame is aligned with the bottom opening of the vessel body. In this pecan beverage extraction device with homogenization assistance, the drive motor rotates the stirring rod. The spiral-shaped stirring blades on the outer wall of the stirring rod, while rotating, cause the material to move in a circular motion. The spiral shape generates axial thrust, promoting the liquid to circulate up and down, enhancing the stirring effect. This allows the extract to fully contact the pecan raw material, effectively increasing the extraction rate of water-soluble active substances, improving the overall extraction effect, reducing raw material waste, strengthening the stirring action, and accelerating the extraction process.

This invention provides a polyp image segmentation method based on depth guidance and a triple decoder. Using RGB images as input, the method expands the channels of the depth image, extracts its multi-layer features, and performs layer-by-layer feature fusion. This effectively utilizes the spatial structural characteristics of polyps in the depth image, enhances multi-scale semantic and spatial location information, and helps the network extract the polyp region more completely. A triple decoder architecture is designed to extract fine-grained detail features and deep semantic features of the polyps. The combined decoder integrates the advantages of both types of features, improving multi-scale feature extraction and fusion capabilities. A high- and low-resolution dual-branch feature extraction strategy is adopted to adapt to high-resolution input. Combined with the advantages of a pre-trained backbone network, this method reduces model computational complexity while ensuring no loss of polyp detail information, thus balancing segmentation performance and operational efficiency.
