7.How does a jar filling machine work?

Now, it’s time to learn the working principle of jar filling machine, do you know how does the machine work? It doesn't matter if you don't know, let's learn it together.

At the beginning, the empty jars are loaded on the conveyor of the jar filling machine, and then the conveyor begins moving and delivers the jars into the filling station. When the jars are moved to the destination, they are stopped and fixed, and then the filling nozzles are aligned with the mouths of jars and then enters them.

At this moment, the filling valve is opened so that the liquid product in the hopper is flowed into the filling nozzles and filled into the empty jars. When the jars are full, the filling operation is stopped and the filling nozzles return to their original position, the filling valve is closed, and there are other jars conveyed here, the above steps are then repeated.

The filled jars are moved to the next station of the whole production line, however, there is a type of machine which is called jar filling and capping machine, it can not only fill liquid product into jars, but also can seal the filled jars. In this machine, the filled jars are conveyed to the capping station and capped.

8.What factors can affect the filling speed of jar filling machine?

Although jar filling machine has a fast speed, there are also some factors may affect the speed of it, they’ll be introduced to you next.

Product Viscosity

The basic factor which may cause influence to the filling speed of jar filling machine is the product viscosity. It is important that which kind of liquid you want to fill with a jar filling machine, the more viscous the liquid, the greater the density, the slower the flow speed, so the filling speed of the jar filling machine is also slower.Conversely, if it is a fluid, less viscous liquid, it will have little effect on the filling speed of the machine

Container Volume

As you know that there are a lot of jars which are in different shapes and sizes, another important factor which will affect the filling speed of the jar filling machine is the container volume. The reason is very simple, in the same time, is it faster to fill a small jar or a larger jar? The answer is of course the small jar.

The Condition of the Machine

To be honest, the condition of the machine itself is also important, the moving parts will be worn after long-times using, therefore, if the components of the jar filling machine are old, the filling speed is naturally low. Therefore, it is a good behavior to check and replace machine parts regularly.
