An automatic oil filling machine operates with minimal human intervention, designed for integration into a continuous production line to achieve high throughput and operational efficiency. These systems automatically handle containers from a unscrambler or conveyor, fill them with a precise volume of oil, apply closures, and discharge them to the next downstream equipment, such as a labeler or case packer. Automation is driven by a PLC, which controls all functions, including the filling mechanism (often piston-based), conveyor indexing, and capping operations. Operators can manage the entire process, set parameters, and monitor production data through an intuitive HMI touchscreen. The key benefits are a significant reduction in labor costs, elimination of manual handling errors, consistent high-speed operation, and enhanced hygiene by limiting human contact with the product. For a large-scale producer of cooking oil, an automatic rotary piston filler with 16 or more heads is essential to meet mass-market demand. Ace-Filling's automatic oil fillers are built for reliability and are designed to be the reliable core of a modern, efficient oil packaging facility, ensuring maximum uptime and productivity.
