A PLC-controlled drink filling machine represents the modern standard in beverage production automation, where a Programmable Logic Controller (PLC) acts as the intelligent central nervous system of the equipment. This computer-based control system supersedes outdated relay logic, providing unparalleled precision, flexibility, and data capabilities. Through an intuitive touchscreen Human-Machine Interface (HMI), operators can input and store recipes for different products, specifying parameters such as fill volume, carbonation pressure (for CSDs), temperature, and production speed. The PLC continuously receives data from a network of sensors (encoders, photoelectric sensors, pressure transducers) and executes the programmed logic to control all actuators (solenoid valves, motors, pumps) with millisecond accuracy. This ensures consistent fill height, manages the delicate counter-pressure process for carbonated drinks, and synchronizes seamlessly with upstream rinsers and downstream cappers. For a brewery producing multiple beer varieties, recipe recall allows for instant changeover between different bottle sizes and fill volumes. Ace-Filling equips its machines with robust PLC systems, providing operators with powerful tools for optimizing production efficiency, reducing changeover times, minimizing product loss, and collecting valuable operational data for analysis and process improvement.
