Welcome to Package This &#; your guide to packaging machinery and materials. The focus of today&#;s episode will be liquid filling equipment, the machines that fill up your favorite beverages and foods as well as non-consumable liquids.
Today, we&#;ll look at the main types of liquid fillers. Choosing the right liquid filler depends on factors including product viscosity, the type of container, the speed of your operation, and other considerations.
Aerosol filling is a unique process used for products like air fresheners, hair spray, deodorant, insecticides, sunscreen, shaving cream, and more. Here we see some various aerosol filling equipment from R.A. Jones in action.
Aerosol filling traditionally consists of several core functions &#; such as product filling, valve inserting, valve crimping, and propellant filling. Also shown here are popular variations such as bag-on-valve and gasser/shaker filling. The exact process and equipment will depend on the specific product and propellants used as well as production line speed requirements.
With over 2,500 machines installed worldwide and 60 years of proven performance, R.A. Jones offers full aerosol production line expertise. They offer both rotary and linear machine platforms covering the complete speed range spectrum.
Flow meter fillers, like the 18-head Exacta Ronchi America, dispense product at a consistent rate. While some flow meters come in an inline configuration, this is a rotary flow meter filler.
Product is measured by a flow meter and the valve is opened or closed to maintain the desired flow rate. This type of filler is well-suited for products that have a predictable flow rate, including water or oil. Ronchi&#;s filler is precise, with a filling accuracy of .2 percent or better.
Ronchi&#;s filler is easily integrated into new and existing lines and is capable of running at speeds of up to 300 bottles per minute. The Exacta is available with a twelve-week lead time, and Ronchi America provides service support, spare parts, and training out of its Dallas, Georgia, facility.
Net weight fillers employ load cells &#; a unit that converts force or weight into an electrical signal &#; that are placed directly beneath the filler.
Because of their precision, net weight fillers can be a good option for any product that needs to be filled to a precise weight, from pharmaceuticals and cosmetics, or in this case, industrial chemicals.
Here we see Specialty Equipment&#;s net weight machine filling liquid product into large pails. The machine doses or dispenses liquid product by weight, ensuring that each container is filled with the exact amount of liquid. Specialty Equipment&#;s machine can fill sixteen, five-gallon open-top pails per minute, or four pails simultaneously. After filling, the machine automatically places the lid onto the pail.
Specialty Equipment can provide this unit with optional pail de-nesting and palletizing features.
Piston fillers fill liquids via a cylinder within a tube that moves up and down to draw liquid from the hopper or tank. This piston is then pushed through a nozzle to fill the container.
Piston fillers are highly versatile: they can handle highly viscous foods such as chunky sauces, glue, and cosmetics, as well as for water-thin liquids and juices, making them a great investment.
Gravity fillers use the simple law of gravity. In this time-based, fill-by-volume approach to filling, containers are positioned below an overhead chamber filled with liquid. Gravity fillers can be a good choice for water-thin or low viscosity liquids, such as soda and water.

If you are looking for a simple, accurate, and cost-effective way to fill containers with liquids, a gravity filler is a good option.
Pressure fillers use displacement pumps, which are pumps that move a fixed volume of product through the machine on a repeated cycle, to create pressure in the liquid, thereby forcing it into the container.
The amount of pressure and the speed of the pump can be adjusted to control the amount of liquid that is dispensed.
Vacuum fillers use a rotary valve pump to create a vacuum that sucks product down into a chamber above the container. This type of filler is typically used for medium viscosity products such as jelly, sauces, and gravy.
Vacuum fillers are also used to fill free-flowing, caustic, and foamy non-foods such as cosmetic products like perfumes, nail polish and colognes into glass and other containers.
And there you have it, an overview of the main types of liquid filling technology! We hope you found it fulfilling!

Packagers rely on liquid filling machines to dispense a variety of liquid-based products. These products do not just include beverages but pharmaceutical and cosmetic products as well. There are many factors to consider when finding the best filling machines for your products. One of those questions to consider is whether you want consistent volumes or fill levels across all your containers. Liquid and volumetric filling machines are two of the most common devices on the market. Each machine provides unique benefits for your packaging needs.
Volumetric filling machines fill containers with a consistent volume of a liquid product. No matter what discrepancies exist within your containers&#; interior volumes, the volumetric fillers guarantee that every bottle contains the same amount of liquid. Some containers may appear less filled or more filled than others, but the volume is consistent.
There are three types of volumetric fillers, including:
Most containers have minor volume variations that naturally occur, even if the containers appear to be the same shape and size. Liquid filling machines can fill your containers to a specific level, regardless of the differences between the volumes in each container.
These machines are also known as overflow filling machines or fill-to-level machines and provide your containers with a cosmetically pleasing fill.
Volumetric filling machines use various nozzles for matching your liquid product. Generally, all nozzles will work the same way by opening for a specific amount of time to let the product flow from the holding tank to the waiting container. Most volumetric fillers allow you to adjust the fill time of each nozzle for greater accuracy.
Liquid filling machines use a nozzle that seals over your containers&#; opening and allows the liquid product to flow back into the tank, eliminating product waste. Additionally, the product withdraws into the return port once the fill reaches a pre-set level in your containers.
Volumetric filling machines are often ideal applications for opaque containers since inconsistencies in the fill level will not be noticeable.
Gravity fillers can be economical solutions for free-flowing liquids that require volumetric fills. Pump and piston fillers can be ideal for handling viscous liquids, like oils and gels, that need extra help before reaching the containers. Piston filling machines can also be used for handling products that contain large particulates.
Liquid filling machines are best for providing cosmetic fills. Therefore, packagers filling clear plastic or glass bottles prefer these machines because consistent fill levels create an aesthetically pleasing appearance.
Overflow filling machines are also ideal for low-viscosity liquids and products that foam and need to be controlled during the filling process.
