How does a piston filling machine work?
While most liquid filling machines are suitable for free-flowing liquids, handling products with particulates or chunks like paste can be difficult. A piston filler solves the problem by allowing versatile filling regardless of the viscosity. The components of the volumetric piston filler make it possible to transfer any products. The hopper in the piston filling equipment holds bulk products to be filled into bottles while the cylinder maintains a constant interior volume to ensure consistent levels during fills. The piston moves the product in the hopper to the cylinder while the valve opens and closes to control the product flow. Nozzles dispense the products from the cylinders to the containers. You can find semi-automatic and automatic fillers. Semi-automatic fillers require manual operation, like placing the containers to be filled into the machine. You have to initiate each fill cycle and manually remove the containers after each fill.
What are the advantages of liquid piston fillers?
Piston filling machines are versatile and provide easy operation and simple controls. You can use piston fillers for thick or thin products. If you are filling containers with thick products, they are pulled into the cylinder when the piston retracts. As the piston moves back to position, the products are pushed out through the nozzles. The space created allows the movement of particulates and seeds in the products. The constant volume of the cylinder in every cycle also ensures accurate volumetric fills and uniform product levels in all containers. The nozzles come in different sizes, and you can find the best type for your products' needs. Since the cylinders and pistons are also available in various sizes, you can fill large and small containers.
