A thick liquid filling machine is specifically engineered to handle products with high viscosity, such as pastes, gels, creams, slurries, food purees, and heavy syrups. These materials do not flow easily and can contain particulates, presenting unique challenges that standard fillers cannot overcome. The unequivocal technology for these applications is the positive displacement piston filler. A piston draws a precise volume of product from a hopper and forcefully pushes it into the container through a wide-diameter nozzle. This positive action ensures accurate volumetric dosing regardless of the product's resistance to flow. Key design features include large hopper openings for easy loading, agitators to keep suspensions mixed, heated jackets to maintain viscosity, and generously sized nozzles and valves to prevent clogging. For extremely sticky products, special nozzle designs with drip-free cut-off are employed. Ace-Filling's thick liquid fillers are built with powerful drives and robust components to handle the high forces required, ensuring that even the most challenging viscous products can be packaged quickly, cleanly, and with exceptional accuracy, which is vital for cost control and product consistency.
