Liquid Filling Machine

Looking for packaging solutions on the liquid can filling machines can be overwhelming. This is especially true for those who are new to the industry.

Piston? Pump? Overflow? Or gravity? Which one of these is the best fit for your project? Of course, the answer will depend on a variety of factors. This includes a packager’s liquid filling requirements.

There are many types of liquid filling machines. Along with the available options which are too many to list for this post. But, we are here to guide you through the process of choosing the right liquid filling machine for you. We have compiled the basic factors you need to consider in this article. So brace on and ready yourselves for some technical details included in this post.

Without further ado, let us now start with our discussion.

 

#1 The Product Type Being Filled

When talking about liquid filling machines, the first question you should ask yourself is: What type of products will I be packaging? Different filling machine types fill different liquid viscosity values.

Can packaging machine manufacturers design some bottle fillers to handle dry goods like pills or powders? But others will be more suitable for handling liquids. Thus, if you plan to buy a liquid filling machine, you should consider your product’s consistency or viscosity. This will help you determine the filling technique your machine must use to handle your item’s attributes properly.

For instance, a thick liquid (highly viscous) product is more suited to be processed using piston fillers than overflow ones. While thin liquids may be more ideal for gravity fillers versus piston filling machines. Though there are filling machines with overlapping viscosity levels, filling specific products can drop other machines from the selection process.

 

#2 The Unique Characteristics of Your Product

Some products can change in viscosity when there is a temperature change. Other liquids may contain particulates like liquid soaps or salad dressings. Any unique characteristics of your product can have a bearing on the type of liquid filler which will best fit your project.

For example, a sauce that contains bits of vegetables might need a piston filling machine. This machine can move the pieces through the machine. Using a gravity filler or an overflow filler for this sauce is not ideal. The chunks can clog the hoses or nozzles of the machine causing a very inefficient process.

Carbonated beverages such as champagne, beer, and soda also need unique types of liquid filling techniques. Along with specialized filling machines. Thus, you would have to consider buying a machine that is designed for the proper filling of carbonated products. These filling machines are called counter pressure liquid fillers.

Counter pressure liquid fillers preserve liquid carbonation even when the product is currently being bottled. It uses a process known as double pre-evacuation. This process works by getting rid of the oxygen inside the containers. Then pressurizing them using carbon dioxide. It repeats the process to remove about 99% of the oxygen inside the containers. Resulting in bottled carbonated products with longer shelf-lives.

So when you properly identify the unique characteristics of your product, you can drop other filling machine types to find your ideal equipment.

#3 The Type of Container or Bottle You Will Use for Packaging Your Product

Another vital factor when you purchase a liquid filling machine is to know your containers’ physical properties.

For instance, packagers who are using clear containers might want to go for overflow fillers. Overflow fillers fill containers at uniform levels. Regardless of slight inconsistencies in each container’s interior volume. This will provide an attractive appearance to the products when they reach the shelf.

Moreover, some automated can fillers grab containers from the top and some from the sides. Therefore, bottles that have unique lids or caps are not suited for filling machines that grab downwards. Similarly, too wide bottles are also not ideal to package using liquid can fillers that grab from the sides.

One more key factor to consider about the type of container you will be using for your products is the material. Is your container made from plastic or glass? Moreover, would you rather use a liquid can filler that is designed for filling aluminum cans than bottles? Of course not. Each container material requires a specific liquid packaging technique that should be compatible with your containers.

 

#4 Your Desired Production Capacity

Your production requirements are another helpful factor to determine your desired filling machine’s automation level. Each type of liquid filling machine can be made as a table-top, semi-automatic, or a fully-automatic machine.

Semi-automatic machines require manual labor in placing the bottles, activating the process, and removing the filled bottles. This might slow down your production process especially if you are aiming for a high production number. Fully automatic machines need less interaction with the operator thus increasing your filling rate dramatically.

Therefore, your required number of filled containers per minute to meet your production demands assists in searching for the ideal equipment for your project.

You should read more on the recommended applications of each type of liquid filling machine to help you choose the right machine for your application.

 

Conclusion:

If you’re a newbie to packaging automation, deciding which liquid filling machine is best suited for your products can be confusing. You will be overwhelmed with the many options and filling machines available.

Aside from the common factors discussed above, there are other questions that you should answer when selecting a liquid filling machine. Other factors like your current budget, future growth, and the possibility of new products will help in identifying the best solution for your project.
