How Does a Liquid Filling Machine Work?

There are many types of liquid filling machines available in the market. Although they vary in design, the main distinguishing factor is the filling technology.

Depending on the type of liquid to fill, you may choose any of these liquid-filling machine processes.

Level Filling Machines

Level-filling machines are devices that operate based on physical markers. The equipment does not rely on set volumes but instead fills containers up to a certain level regardless of the shape or size of the container. It offers a more efficient and effective dispensing solution.

Working Principle

The level-filling machine is comprised of a main supply tank that contains the product which is then pumped into the feeding line. Its feeding line is equipped with a two-way nozzle that is set to a certain level. The nozzle is capable of both dispensing products and suctioning any excess liquid from the container

The excess liquid collected is then pushed into an overflow tank. This tank is equipped with a pump that draws the product from the main supply into the tank and a float switch that helps to maintain the recommended level of product. Once it is filled the tank drains the product back into the main tank.

Weight Filling Machines

The weight-filling machine is an equipment that relies on measured quantities when dispensing the liquid into a container. This system has an increased level of accuracy while reducing any form of wastage. It I equally compatible with a broad range of products and containers.

Working Principle

Weight-filling machines are equipped with a weighing container. Liquid from the main supply is directed to the weighing container which is filled until the recommended weight is achieved. The weighed liquid is then dispensed into its respective container and the process is repeated for the next container. You can alter the parameters and set different weight limits for different containers with varying weight categories.

Volumetric Filling Machines

Volumetric filling machines are devices that dispense liquid according to a set volume. This device is not only cost-effective, it is also highly efficient and is ideal for large-scale productions. Three main categories of volumetric filling machines achieve the required results using different techniques.

Pump Filling

Working Principle

This variation of the volumetric filler relies on a variety of different pumps to establish the flow of the product and to dispense the liquid into their respective containers. The pumps utilize their moving parts to create a positive displacement of fluid. The device utilizes pulse timing that relies on gear revolutions to dispense the correct volume of liquid into the respective containers.

Gravity Fed System

Working Principle

The gravity-fed system has a simple working principle. This device relies on gravity to dispense a set volume of liquid into the container. Its main supply tank is typically set up on a raised platform to allow for the liquid to flow down into its respective containers through valves. The volume of the liquid is determined using a precise timer that calculates how long a liquid passes through before the valve shuts off the flow.

Piston Filling Machine

Working Principle

This variation of the volumetric filling machine is equipped with valves that open up to allow liquid to flow through to the cylinder from the hopper.

Once the set volume of liquid is attained the liquid is driven through nozzles and dispensed into their respective container.

In short, you can see the filling technique varies depending on the technology. Before buying a machine, you must understand how the machine works.
