In recent history, the packaging industry has seen a lot of improvements. Because of this, every company in the industry needed to improve their systems in order to keep up with the ever evolving demand on the current market.
Finding and getting the right equipment can be tricky. Depending on what part of the industry you are working in, your machines need to meet certain industry standards. Whether it is a safety standard or a sanitary one, getting the right equipment is simply a must. That being said, if you want to learn about various liquid packaging systems and which one is the right choice for you, we recommend that you stay and read on.
Types of Liquid Packaging Systems
Before you decide which packaging machine you want to buy, there are some things that you need to consider in advance.
To begin with, the most important thing is to understand what type of liquid you are working with considering that every liquid is different. For example, the most notable difference between liquids is the viscosity. Understanding if the liquid you are working with has high or low viscosity will ultimately determine what type of machine you will be getting. Liquid, like water, that has low viscosity is easier to work with compared to liquids with high viscosity such as pastes and gels.
Furthermore, the next thing that you need to think about is the purpose of the liquid you are working with. What we mean by this is that different liquid filling equipment is specifically designed to work with specific liquids. For example, if you are working with a liquid that is sensitive to contamination needs to be packaged according to regulations. Due to this fact, liquid filling equipment manufacturers needed to start making the machines according to those standards.
Additionally, another thing that you need to keep in mind is the type of container you are using. In order for everything to function normally, your machines need to be able to actually fill the said container without any issues. So, let’s say that you just bought a bottle unscrambling machine; it is natural that you would want to make sure it is going to work with your production setup. Finally, do not forget about the fill rate and volume of the liquid.
With all of that in mind, let’s go into more detail.
Different Filling Machines
Molten Filler
A molten filler is a liquid filling device that uses high-temperature liquids, as you can obviously infer from the name. While the liquids are still very hot, these machines fill the containers with them. After the liquids cool, they are then dispatched to be properly packed. Packaging materials such as those for candles, deodorants, and soaps often contain molten fillers.
Pump Filler
They function similarly to a Swiss army knife when it comes to pump fills. These devices are so adaptable that they can fill a wide range of liquids with various viscosities. Additionally, depending on the kind of liquids you are working with, they might operate on a variety of principles.
Inline Filler
The ideal way to fill containers on a conveyor system that are traveling in a line is using an inline filler. They can fill many containers at once without affecting the fill rate, which makes them incredibly efficient. Additionally, inline fillers resemble pump fillers in certain ways. They are utilized throughout the industry for different liquids and are quite adaptable.
Pressure Filler
Thicker liquids are typically packaged using pressure fillers. Their operating mechanism makes use of various valves and pumping systems as well as gravity.
Gravity Filler
One of the most popular machines in the field is this one. Juices, water, and sodas in general are among the liquids that gravitational filers are most frequently employed to fill. Depending on your requirements, they may reach a variety of fill speeds. Their fundamental operating concept is obviously obvious from their name. Due to the unique way in which their valves are constructed, these machines fill the containers using gravity.
Rotary Filler
When it comes to rotary fillers, they differ slightly from the other equipment we have covered here so far. To begin with, these machines have circular stations, which imply that several procedures are performed at each station. The container is initially filled before leaving the station. Then it is transferred to the following section, where it is closed, and finally, on the third section, it is totally sealed and prepared for shipping.
Net Weigh Filler
Net weigh fillers are the last packaging machine we will talk about. When filling containers, these machines provide a specialized function. They are utilized when a certain volume of liquid must be stored in a container. This implies that each and every container must be accurately and properly filled. These machines are quick and accurate enough to manage heavy product demand. They are typically used with the more expensive liquids.
