Core Viewpoint - The introduction of the first domestically produced automated grain continuous unloading machine at Shandong Port's Rizhao Port represents a significant technological breakthrough in the grain unloading sector, achieving 100% localization of core technologies and key components, with a maximum unloading efficiency of 1,500 tons per hour [1][2]. Group 1: Technological Innovation - The new unloading machine incorporates four major technologies: spiral material extraction, vertical lifting and horizontal transportation, dynamic dust-free material transfer, and fully automated operation control, breaking the foreign technology monopoly [1][2]. - The machine's design allows for automatic and precise identification of cargo points within the ship's hold, enabling efficient operations without manual intervention [2]. Group 2: Economic Impact - The introduction of this technology has reduced labor costs at the port by 50%, and the energy consumption per ton has decreased from 0.4 kWh to 0.27 kWh, resulting in annual electricity savings of 1.85 million kWh [3]. - Based on an annual unloading volume of 1 million tons, the port could save over one million yuan in electricity costs alone [3]. Group 3: Industry Context - Previously, continuous unloading machines used at grain terminals were primarily foreign products, with high procurement costs in the tens of millions and reliance on imported core components, leading to high maintenance costs and potential operational risks [2]. - The new machine's smaller size, lighter weight, and lower energy consumption provide advantages over similar foreign equipment, enhancing performance and efficiency while reducing investment costs [2].
