filling types

GRAVITY Fill

Using the basic principles of gravity, containers fill to a specific level with no electronic controls.  Containers are raised to the filling valves, where they are positively sealed to the valve sleeves. As containers continue their upward travel, the valves open.  Once opened, it vents air in the container to the fill bowl and product flow begins. Once product levels in the container reach the bottom of the valve sleeve, the valve’s air vent is blocked and the product flow stops.  Fill level is simply adjusted by adding or removing spacers from the valve sleeve. Since containers seal with the filling valves during the filling process, it vents any foam generated back to the fill bowl rather than escape out the top of the container.

Gravity filling systems are fast, accurate, reliable, and affordable with very low annual operating costs.

Pressure Fill

Similar to gravity filling systems, a pressure filler will also make a positive seal between the filling valve and the container, filling the container to a desired fill level for ideal product display. This system adds a pressure element to the formula, aiding in filling viscous products. Using a specifically designed pump the product is not agitated or broken down during the fill process.

Pressure gravity filling systems can handle more viscous products, can be faster in speed, equally efficient, with low annual operating costs.  

MASS-FLOW METERED

Using a coriolis mass flow meter, containers are filled to a specified mass, or volume within .02%., thus, making this system the most accurate in the industry. While utilizing a pump to maintain product pressure, communication between the flow meter and control valve is continuous, and the flow meter will adapt to any fluctuation in the valve to achieve maximum accuracy. Without the need for a positive seal on the container, containers can remain on the same plane for maximum container control.

Mass-flow systems are fast, most efficient, and eliminate product waste. While these systems are highest in cost, the offset in product savings due to increased fill accuracy can quickly pay for themselves.
