Common Liquid Filling Machine Designs You Should Know

Filling machine – this phrase appears to be self-descriptive which means a machine used to fill something. For liquid filling machines, this something is a liquid product that is filled into a jar, bottle, or any type of container.

But, you will not find two liquid fillers that are built exactly the same. The only exception is when a packaging line uses multiple fillers in the same design to meet their production demands. A liquid filling machine’s design will depend on a lot of different factors. Moreover, it is not possible to create a single machine that can handle all liquid types.

So in today’s discussion, we will be talking about some of the common designs of a liquid filling machine and why you should prefer one over the other. These designs include the different filling principle and machine automation levels. Keep on reading to know more!

Designs According to The Machine’s Filling Principle

The filling principle that a machine should be using will obviously affect the filling machine’s design directly. Below are the 3 most popular liquid filling principles used in the packaging industry.

Gravity Fillers

Gravity fillers use tanks that are installed above the filling nozzles. The tanks contain the liquid product that will be filled into the containers. In gravity filling machines, the product flows through tubes and to the nozzles by gravity.

The operator can set the fill time of each individual nozzle to achieve accuracy. Free-flowing liquid products requiring volumetric fills are ideal for these types of machines.

Overflow Fillers

These filling machines use the overflow filling principle as suggested by the name. They use recirculation tanks that allow the liquid to overflow from the container once the fill reaches a specific level.

The overflowing liquid will move back into the tank and will be used for the next fill cycle. And instead of volume filling, overflow fillers fill up to consistent levels on each container even if there are slight volume differences.

Piston Fillers

Piston fillers first fill the product into a cylinder then use pistons to push the product from this cylinder into waiting bottles below the nozzles. They also use volumetric fills but they are more suitable for filling highly viscous products. These products are not free-flowing and need extra help to reach the containers.

Gravity filling, overflow filling, and piston filling are only some of the principles you can use for your projects. However, the machine design can vary from a hopper, raised tank, and ground-level tank.

Designs According to The Machine’s Automation Level

Automation levels can also help determine whether fully automatic or semi-automatic fillers are the right solution for your filling project.

Semi-Automatic Filling Machines

Liquid fillers in semi-automatic automation can utilize the majority of the aforementioned filling principles. These machines require the operator to manually place the containers into the machine for filling. Thus, they are ideal for smaller productions.

Tabletop machines are the most popular types of semi-automatic can fillers. They have designs that allow enough room for operators to move the containers to and from the machine in each cycle.

Fully Automatic Filling Machines

Contrastingly, fully automatic fillers are not ideal to have tabletop designs because the tabletop will be useless. These fillers are manufactured on fully portable frames that allow the installation of a conveyor system to automatically fill containers.

Unlike semi-automatic filling machines, fully automatic fillers do not require much interaction with the operator because the whole process is automated. This makes fully automatic filling machines suitable for high-volume productions.

Common Factors Affecting the Design of a Liquid Filling Machine

Of course, the filling principle and automation level you want your liquid filler to have will affect your machine’s design. But aside from these, your container and product can also be influencing factors.

For instance, small containers like tubes or vials may require monoblock filling lines. These lines use starwheels to stabilize the containers while they are being filled. A starwheel is simply a grooved wheel that holds the containers and then rotates to position the container below the filling nozzle.

Moreover, vials or tubes with rounded bottoms are not suitable to be used with power conveyors without any assistance. Power conveyors move too quickly which can cause the vials/tubes to fall over. One recommended solution is to use pucks to keep the small containers stable while moving through the conveyor.

Conclusion

When you are looking for a liquid filling machine for your project, you will be given a lot of design options. The once mentioned in our discussion are only the common ones. The main point is, there is a wide variety of possible liquid filling machine designs depending on your application. Here is a guide you can read on how to choose the right filling equipment for your product.

If you are still not sure which machine design is the right one for you, better choose a manufacturer that includes free consultation services. Through this, you will have a tin can packaging machine guaranteed to meet your specific requirements.
