What is an Overflow Filler?

The filling industry has progressed a lot during the past few years, especially technology-wise. Keeping up with it has become a necessity if you want your business to succeed. These machines will help you keep up with your competition as well as help cut down costs and reduce waste. As we said, there are a lot of different filling machines on the market right now, and all of them serve a different purpose. That being said, today we will talk about the overflow filler. We will go over everything that you need to know about these machines. What is an overflow filler and how does it work are just a few questions we will answer for you today. Additionally, we are going to talk about some advantages and disadvantages that an overflow filler brings to your production line. With that out of the way, let’s not waste any more time.

The Overflow Filler

Basically, an overflow filler is a machine in the packaging process that perfectly fills each and every bottle to the same level. As a bottle filling machine, it does not focus on the interior volume of the container. That means this machine does not work by measuring weight or volume, but rather, it uses a nozzle to measure when a certain liquid reaches a desired level in the bottle. The machine then creates a seal over the bottle so the product is allowed to recirculate. This way of filling is unique to the overflow filler. The overflow filling machine is so versatile with its unique nozzle. You can use them to create semi-automatic as well as fully automatic bottle fillers while the principle behind it remains the same regardless of the level of automation you have.

The way that these machines work is that the nozzle, when it descends into the bottle, creates a seal in order to prevent any leakage while the bottle is being filled. When it comes to the exact amount filled, there are spacers used for the nozzle to ensure that there is no mistake on that part. Furthermore, the spacers are specially designed so that you can adjust them easily on every nozzle in order to perfectly control how much you want to fill a certain container. Additionally, the machine also has easily adjustable nozzle height as well as width. This means that a single overflow filler is capable of handling a lot of different bottle sizes, but also shapes. The main advantage of this machine when it comes to products is that they will all look the same. This is especially important for clear containers.

The Principle Behind It

As we mentioned, an overflow filler machine is a versatile machine that can fill plenty of different liquids that have different consistencies. Additionally, when it comes to filling up clear containers, the main advantage is that they will all be perfectly filled to the same level. This is important as when these products are on the shelves, they will look unified and more pleasant to the eye. Now, we are going into a bit more detail regarding the principle behind the overflow filler machine.

How it Works

First things first, through the two-part supply side of the nozzle, the product is pumped into the container. Then, when the container is filled to the desired level, the excess foam and product are forced out to the tank from which the product came through the return side.

The Use

Usually, the overflow filler is used for low to medium-viscosity liquids. That being said, these machines can handle more solid liquids, but only if they do not exceed 1/16 inches particulates. Furthermore, these machines are the top choice for productions that deal with products that tend to be very foamy and are filled at high speeds.

Advantages and Disadvantages

First of all, let us cover the advantages of overflow filler machines. One of the main advantages is that these machines can be used to fill plenty of different bottles and containers. Furthermore, it can handle a variety of liquids with different consistencies. Also, they are very efficient as well as fast. Not to mention that they are really easy to maintain and also operate. Additionally, the machine is very versatile and adjustable, making it cost-effective. Lastly, it works great with foamy liquids as the machine keeps the container sealed as it is being filled.

On the other hand, there are some small disadvantages. First of all, the machine can fill a variety of liquids with different consistencies. However, only to a certain point. If a liquid exceeds a viscosity of more than 1/16 inches particulates, then an overflow filler is not up to the job. Last but not least, these machines are not really suited to fill large containers at all.
