Liquid filling machine trends: Today's equipment is more versatile

Whether you’re a newcomer to the world of liquid filling equipment or an experienced

user looking to upgrade or change your production line, browsing websites and product

catalogues in the search to source a suitable machine can be more than a little


Overflow or gravity machine? Piston or pump? Automatic, semi-automatic or manual? Hot

or cold-filling? In-line or rotary filling? Off-the-shelf or turnkey? Fortunately, with

so many choices out there you’re likely to find the ideal solution for your particular

application – however, finding it requires that you do a bit of homework and adopt a

systematic approach.

To simplify the process, you may find this guide to liquid filling equipment useful.

It identifies key questions which will help you narrow down your search and focus only on

those systems that meet your objectives.

The first question to ask is what product is being filled?

Not all liquids are the same. Some are free-flowing, others are very viscous. Some

contain particulates or flammable ingredients, others are foamy whilst the viscosity of

some products may change when the temperature changes. The important thing to remember is

that type of liquid filling equipment that you choose has to be compatible with the

product type. For example, a gravity filler is more suitable for thin products, piston

fillers are a better option for thick products than overflow filling machines and

bottom-up filling machines are used for foamy products.

Another key question to ask is what type of container is being filled?

In many instances, the type of container or bottle will dictate the type of filling

technique and the more you know about the attributes of the container, the better. What

material is it made from (e.g. glass, aluminium, plastic) and what are its dimensions and

characteristics? This information is important because it will determine the optimum

performance of the equipment and the best equipment type. For example, an automatic

bottle filler which grabs a container from the side may not actually be the best option

if your container is very wide and a top filler may not work if your container has an

unusually-shaped cap or lid.

You need to ask how many containers do you want to fill every hour?

Knowing your production rate is also a crucial factor in your equipment selection.

A semi-automatic filling machine would be a cost-effective and reliable solution for

smaller production runs like those in a laboratory or in a start-up venture, whilst an

automatic filling machine with a sizeable conveyor is ideal for larger-scale operations

with much higher production rates. For operations with very low production rates and no

expansion plans such as a home brewing venture or small-scale home-made sauce business, a

manual machine could fit the bill.

You also need to ask yourself, how do you want the final fill-level in your container

or bottles to look?

Appearance does count, and different filling systems have different outcomes. For

example, a liquid level machine will fill every container to the same specified level

regardless of the volume of the product, making it a preferred product where uniformity

is important. On the other hand, a volumetric filler will fill a container with the

identical volume of liquid even when the fill levels may appear to be variable.

Volumetric fillers generally cost more as they require specialized instruments for

calibration, balance and timing.

Some of the types of

liquid filling machine

gravity fed fillers (a good, cost-effective option for efficient volumetric filling

especially for low viscosity and foamy liquids);

piston fillers which use a highly accurate volumetric filling technique, ideal for

thick or highly viscous liquids. These are divided into two types, namely check-valve

piston fillers and rotary valve piston fillers;

pump fillers which are very versatile and suitable for a wide range of liquids and


in-line filling machines (a cost-effective choice for filling containers in a line)

which are suitable for those operations where different container sizes are involved; and

rotary filling machines (which are often much larger and more specialized) for faster

speeds and higher production rates.

Another question is whether your filling equipment can be modified if your needs


It’s often not necessary to buy new equipment just because your business has

expanded or you want to add new products or packaging to your line. An experienced

manufacturer will have the knowledge and skills to advise whether your liquid filling

system can be modified and will make recommendations to future-proof your investment.

Choosing the best liquid filling equipment is a complex decision and many factors

need to be considered. From product characteristics and container attributes to fill

size, production rates, regulatory issues, safety requirements and expansion plans, if

you answer the questions highlighted above, you’ll be in a strong position to make an

informed choice which factors in all of these issues.

However, your best option is to talk directly to industry professionals, like

AccuPak. They are one of Australia’s largest suppliers of all types of packing and

filling equipment and they will work with you to identify the most cost-effective and

practical solution. They know the critical factors required from all packing, filling,

bagging and palletizing machinery and equipment - i.e. versatility, flexibility,

reliability, accuracy and affordability.

All About Liquid Bottle Filling Machine

If you are into the packaging industry, then you must have heard about ‘liquid

bottle filling machines’. These high-grade machines are designed especially for

packaging products in liquid form.

liquid form that ensure efficiency and precision. With the invention of Liquid bottle

filling machines, companies have now started packaging liquid

products in bulk, which are easy to port and

can be handled efficiently. The machines are designed in a way that guarantees purity and

maintains hygiene standards.

Now that you know what a liquid bottle filling machine is, understand how it can

benefit your business:

Faster and more efficient filling

Automatic Bottle Filler machines can help companies to consistently fill bottles with

liquid products by avoiding errors and minimizing waste. These machines make it possible

for industries such as pharmaceuticals to packaging their products in liquid form with


Helps Maintain Hygiene Standards

If you are in the food industry or even the pharmaceutical industry, then you know

the importance of maintaining proper hygiene standards. Manually filling with them

bottles leaves room for error. With an automatic liquid

bottle filling machine

, liquids enter into the bottle with the press of a button, and you can monitor the

whole process to avoid any malfunction.

The flexibility of the machines allows you to save time

The higher the speed of the machine, the more you can save time. Perhaps the biggest

advantage to companies using this machine is speed and its flexible nature. Liquid

Automatic filler machines can fill more than 80 bottles per minute; this high speed can

help companies fulfilling their orders.

The flexible nature of the automatic bottle filling machine allows for a seamless

operation. Not only are these machines convenient, but also allow you to adjust the speed

and height of the bottles. This machine is designed to achieve maximum output and

increase the growth of your company.

Uses of Liquid Bottle Filling Machines:

Pharmaceutical Product Packaging: Packaging of pharmaceutical products of liquids is

very essential for the growth of the industry. The liquid bottle filling machines offers

flawless operation that bottles are user friendly and prevent contaminants entering into

the bottle.

Versatile application of the machine: Many local drug-making companies are using

these machines to process vial filling, tube filling, powder filling, and syringe filling

to package their products innovatively.

Cosmetic and food industry: Liquid filling machines effectively help in sealing syrup, oil, and other

liquid products. Milk bottles and grape wine bottles are a few examples of how the food

industry is revolutionizing its packaging process.

Holden also notes that brands in the snack industry have been implementing reusable

cases—often printed with branding—that drivers return to the processing site. This has

lead to rising demand for case packer

s that can accommodate reusable cases.

Case aligning and closing mechanisms are fully integrated, removing the need for

additional conveyors and creating an all-in-one case packing solution. An integratable

seal checker checks for defective packs, while the system features gentle, vacuum-free

bag handling. Changeovers can routinely be performed in 3 minutes, with preset options

that allow for the machine to be automatically set up without the need for tools or any

other manual operation.
