How does Can Filling Machine Work?

An overview of the filling machine

In the entire bottling line, the most important machine is, without a doubt, the filling machine. It is the only machine which comes directly in contact with the finished product and, therefore, must guarantee maximum reliability in terms of hygiene and quality of the final product. That is, it must preserve the characteristics of the product during the filling phase and allow its easy cleaning or, if in contact with products especially sensitive to contamination, its sterilization. During the filling phase, liquid products can be foamy, dense, creamy, fluid, powdered, or granulated.

 

Likewise, these products can be packaged and presented in special containers, such as bottles, vials, jars, cans, cans, tanks, buckets, and more. Sometimes, the identity of the filling machines are according to the type of packaging container for the finished product. For example, the glass bottle filling machine, the can filling machine and so on.

 

There are different filling processes which (by isobaric pressure, gravity, negative pressure, etc.) in which different types of filling machines are used, such as mechanical weighing units, gravity fillers with electronic or volumetric fillers with dosing syringes, or fillers by negative pressure with constant values ​​(suitable only for very rigid containers). The machines are configured and calibrated to guarantee perfect operation and exceptional accuracy.

 

Also, you can categorize the various filling machines according to the level of automation. For example, we have the tabletop filling machine, the semi-automatic filling machine, and the fully automated filling machine with the highest level of automation.

 

In this article, we are going to be focusing on the can filling machine and its working principle.

The can filling machine represents one of the packaging machinery used for different kinds of beverages ranging from the non-alcoholic juice to alcoholic beverages. The difference between this filling machine and the traditional PET bottle filling machines is the fact that the final product packaged in an aluminum can.

Overview of how the can filling machine works

 

The can filling machine works with the same principle as the conventional liquid filling machines. The sterile cans are fed to the filer by conveyor mechanism unto a platform. The platform rises and falls to meet up the filler valve which is positioned above it. The mouth of the can is then pushed against the filling device to ensure an airtight condition. With the help of the vacuum placed above, the air is further removed as the cans rotate. The filling of the can commences, and once the liquid rises to the required level, the air is no longer removed. Hence, the can is removed, and the operation can be terminated at this point.

 

Before purchasing a can filling machine for your small or medium scale business, it is important to consider factors such as the size of the machine which will affect your storage space, the durability of the equipment as will be obtained from reliable can filling machine suppliers, the level of automation, maintenance manual and more.
