Liquid bottling machine in modern industry

Finding the best bottle filling machine for your needs.Here are factors that should be considered when searching for the correct liquid filling machine for your product line. Bottling machinery selection is driven by your product characteristics, viscosity being the primary metric. Peanut butter is put in a bottle by a liquid filling machine, as is acetone. Peanut butter and acetone are both liquids but at opposite ends of the viscosity range. The bottling machinery needed to move peanut butter into a bottle is very different than the bottle filling machinery used for acetone.

What type of filling equipment is best suited for your product viscosity and other characteristics? There are four different liquid filler technologies, piston, timed flow, metered flow, and overflow. Peanut butter is best handled by a piston filler that keeps the product warm and therefore at a lower viscosity, all driven by a strong pneumatic cylinder. Acetone, on the other hand, can be gravity fed into an overflow filler.

Volumetric Fillers
In a piston filler, piston diameter and stroke length determine the product volume delivered to the bottle. Change the stroke length to deliver a different quantity of product to the container. Piston bottle fillers are best with higher viscosity liquids or filling liquids containing chunks of fruit or vegetables.

Timed Flow Fillers
These fillers use time to meter your product if you have a filling machine that delivers product at a consistent flow rate. Light oils and aqueous solutions work well in this type of bottling machine.

Metered Flow Fillers
Use a gear or lobe pump to deliver the product at a consistent volume determined by pump shaft rotations. This type of metered flow filling machine lends itself to thicker products without particulates in the liquid.

Overflow Fillers
Overflow oil filling machine are also used for light oils and aqueous products where the product needs to be filled to the same visual level. The product on the shelf will appear to be filled to the same level irrespective of container fluctuations.

Bottle Selection
Selecting a bottle is the next step as you design your liquid filling system. A simple straight-sided round bottle can be handled by off the shelf components. If you choose a novelty container, you will increase the time to design manufacture and test your bottling machine.

As a business starts and expands, the needed production rates from their bottling machinery increases. A startup company’s first filling machine may fill a single bottle at a time with an operator handling the containers by hand before and after filling. Increasing the number of nozzles on a bottling machine increases production rates. Bottling machines that have as many as twelve nozzles filling at the same time are not uncommon. In these filling systems, a conveyor belt moves the containers under the nozzles, pauses while the liquid fills the bottles, and then moves the filled containers out.

Zeno filling machine offer a wide variety of bottle filling, capping, and labeling machines. We pride ourselves on being able to support startup companies that need economical semi-automatic bottle fillers. We also have the depth of experience needed to service mature companies with world-class technology, providing automatic packaging lines at competitive prices.
