Liquid Filling Machine

1.What Is A Liquid Filling Machine?

Liquid filling machines are mostly used in pharmaceutical, cosmetics, beverages and food industry where liquid is to be filled in various types of containers, jars and bottles. Liquid filling machines are highly precise that the volume of liquid has a filling tolerance of only ± 0.5 ml. This makes them too accurate and efficient for production setups.

It is an easy way to fill liquid in a quick manner using a liquid filling machine and replacing the traditional filling practices where human errors were a common disadvantage. A liquid filling machine also ensures less wastage of material.

2.In Which Industries Are These Liquid Filling Machines Used?  

Common applications of a liquid filling machine are

Food and Beverages Industry

Liquid or viscous products are also filled, sealed and wrapped using a liquid filling machine. Beverages in bottle and containers are also properly filled with high quality and precision.

Cosmetic Industry

Liquid materials used as cosmetic products like cream, lotions, creams, moisturizers and other are filled using a liquid filling machine.

Medical Industry

Liquid filling machines are used to store sterilized liquid products like medicines and other in sterilized conditions. It helps to avoid cross contamination and increase the shelf life of products. Products like hand wash and shampoo are also filled using a liquid filling machine.

3.What Is The Working Principle Of A Liquid Filling Machine?

Like other filling machines, a liquid filling machine also has the same working principle. The only difference between them is that a liquid filling machine requires high pressure to fill the containers or bottle in a precise manner. Following is the working principle of a liquid filling machine.

• Initially all the parameters of machine like speed, temperature, pressure etc. are set according to the viscosity and nature of liquid.
• After that the feeding pan is filled with the mixture that is to be filled in the container. The pan mixes it well to achieve the desire composition.
• The liquid then travels from feeding pan to the discharge tube where it exits the system. Meanwhile, containers are set in a proper conveyor system and moved in sync with the help of sensors.

• As the liquid and container both reaches the filling head, the container gets filled and proceeded to next step.
• Rotations are also done for proper wrapping, covering and sealing of containers in a single machine. Highly efficient working is carried out to have same products of same quality.

4.What Are The Main Components Of A Liquid Filling Machine?

Main Components of a Liquid Filling Machine

Some of the main components of a liquid filling machine are

Feeding Pan / Hopper

The most important component of a liquid filling machine is a feeding pan. This is the area where the product actually gets mixed and is prepared to be filled in the filling object. Hoppers are also there to control the exit of feeding material.

Filling Head

A filling head is the part which gets contact with the packaging material like bottle, jar, container etc. It allows the mixed product to enter in those packaging materials.

Mechanical Drive System

This drive system is responsible for the mechanism of whole packaging material movement. A mechanical drive system ensures that the movement of packaging material is synchronized with that of the amount of liquid released from the filling head. A minor delay or excess speed can damage the whole production line.

Sensors

Sensors transmit signals that indicate the presence of packaging object. These are also responsible for making a synchronize relationship between the movement of object and filling unit. It allows the container to enter in the filling unit only when it is empty to avoid overlapping of containers.

Control Panel

The operational parameters like speed, quantity, liquid volume, power and others of a liquid filling machine are controlled through this control panel.

Control System

The automation of a liquid filling machine is through this control system. Nowadays mostly PLCs (Programmable Logic Controllers) are used for monitor and control all the activities performed by these liquid filling machines.

Monitoring System

HMI or Human Machine Interface is the virtual display of all the activities that are carried out in a liquid filling machine. It allows a monitoring display to the operator which helps to control the operations of machine.

13.What Are The Important Factors That Should Be Considered Before Buying A Liquid Filling Machine?

Before going to purchase a liquid filling machine is always necessary to consider the production targets of an organization as it requires a lot of initial investment. Some of the important factors to be considered before buying a job are.

Piston Pressure

Mostly the filling process of a liquid filling machine depends on the power and pressure of pistons that are present in cylinders of filling tank. The material and strength of these pistons should be closely monitored because these are the main components to handle mass production requirements.

Product Viscosity

There are different types of products that are filled using a liquid filling machine. Each of the liquid has its own viscosity and this lies as the main feature of those. The greater the viscous, greater filling time will be there if the machine is not selected properly. Versatile machines that can handle every type of viscous liquid are always a better consideration by different industries.

Liquid Filling Productivity

Small, medium or large scale industry should select liquid filling machines depending upon their annual production need. Manual liquid filling machine offers the least rate but automatic machine can fill thousands of bottles per hour.

Type of Container

It is always under consideration that what type of liquid container is incorporated along with the machine and what is the structure made up of. As liquid stays there for longer period therefore material of container should be moister, humid and contamination resistive.

Also the size of container means a lot. Small container cannot be used in large scare industries or heavy production setups.
