Liquid Filling Machine

PPSI offers two types of liquid filling equipment namely: Piston Type Liquid Filling Machine and Vacuum Liquid Filling Machine.

The Piston Type Liquid Filling Machine is a volumetric type liquid filler. It can accurately dispense a specified volume of liquid into a container. It is suitable for most types of liquids ranging from free flowing to viscous. It is the preferred filling method for products requiring minimum air exposure as it operates in a closed system.

The Vacuum Liquid Filling Machine is a liquid level type filler which means it dispenses an amount of liquid based on the volume capacity of a container. The liquid level of each filled bottle will appear the same when put side by side. However, the liquid volume will differ corresponding to the slight differences of the container volume. This filling method is applicable for liquids that may be aerated and free flowing such as alcohol and mouthwash.

Our filling machines are flexible as they can be used for different products, bottle types and sizes with the use of additional machine parts.

Piston Type Liquid Filling Machine

The Piston Type Liquid Filling Machine utilizes a check valve system that opens during the in-feed stroke, thereby suctioning the fluid into the cylinder. It then closes on the discharge stroke, releasing the fluid from the cylinder and through the filling nozzles. The Filling Assembly may come with four, six or eight volumetric piston pumps depending on the customer's output requirement.

Features:

Complies with cGMP standards
Output volume of each filling pump can be adjusted tool-free through the volumetric adjustment assembly
Machine parts that come in contact with the product are made of stainless steel 316
Uses bottom-up filling motion to avoid foaming and dripping
No bottle, no fill program
Quick and easy changeovers made possible by hand tightened locks and simple tool-assisted adjustments
Easy cleaning through highly accessible machine parts and removable filling pumps and nozzles
Comes with sanitary conveyor

Output rate:

up to 60 bottles per minute(bpm) for single row and 120 bpm for double row(may vary depending on product volume and viscosity)

Vacuum Filling Machine

The Vacuum Liquid Filling Machine can perform the fill operation in two ways.

If the container is rigid, a Vacuum Induced Filling Process is more appropriate since it will not collapse when performing as part of the vacuum system. In this type, the bottle opening is sealed air-tight by the nozzle assembly which simultaneously opens the vacuum port of the nozzle. The filling liquid is then induced into the bottle due to the vacuum. After the appropriate filling time and level has been reached, the nozzle assembly is automatically raised.

If the container is collapsible which is typical of thin-walled PET bottles, then a Positive and Vacuum Pressure Filling Process is appropriate. The difference of this process is that the filling liquid is pumped into the bottle and not filled through the suctioning of a vacuum. The vacuum cannot be used because the bottle will collapse as air is suctioned out from it. The vacuum operation only begins when the bottles are already filled with the product with the purpose of returning the excess product back to the source tank.

This machine can be supplied with 12 to 20 filling nozzles based on the customer’s output requirement and container specifications.

Features:

Stainless steel 316 nozzles with spring-loaded bottle centering guides to ensure consistent vacuum sealing
Maximum of 20 nozzles for high capacity filling
Pneumatic cylinder driven nozzle lifting and lowering
Single height adjustment lever for simultaneous adjustment of all nozzle heights
Stainless steel 316 vacuum chamber with sight-glass
Machine parts that come in contact with the product is made of stainless steel 316
Stainless steel 304 machine body cover
Automatic chamber flushing to prevent vacuum chamber overflow
Timing and operation sequence dictated by a Programmable Logic Controller, for consistent and accurate operation
No bottle, no fill operation
Quick changeovers made possible by hand tightened locks and simple tool-assisted adjustments
Minimal changeover requirements (for different product volume, just change the nozzles if necessary)
Easy cleaning through highly accessible machine parts and removable filling nozzles
Comes with sanitary conveyor
Majority of moving components are pneumatic-driven, resulting in less maintenance requirements and mechanical wear
Option for pump and vacuum combination for collapsible containers
