What Are The Factors To Consider During Selection Of Chocolate Filler Machine?

These machines are custom built depending on the project or product you are handling. There are several factors to consider that differ depending on the project at hand.

Here are some factors that are worth considering when selecting a chocolate filler machine:

Viscosity Of Chocolate Product

There are chocolate fillers that can better handle thick or thin products, while others can handle both. Ensure you consider the viscosity of the chocolate product as this determines if the filler can handle the filling process.

For example, overflow chocolate fillers are suitable for free-flowing chocolate products. Besides, this machine cannot handle thick chocolate products.

When filling thick chocolate products, a piston or pump chocolate filler machine is suitable for your application.

Filling Principle

The viscosity of the product should make you decide the filling principle suitable for your operations. You may select overflow chocolate fillers to fill every product repeatedly to the same levels.

These chocolate fillers are suitable when you are using clear, see-through containers. There are other products that you will fill by volume thereby requiring you to use gravity or piston chocolate fillers.

These products may have varying levels from one container to another, but the volume will be the same.


If you require high production speeds to meet high demands, you need to select fully automatic chocolate filler machines.

For instance, if you plan to have a small production capacity, a semi-automatic or tabletop chocolate filler machine is suitable for your application.

Besides, these two versions allow you to upgrade in the future if the need arises. Also, when you plan to upgrade your small production in the future, you are better off with automatic chocolate filler machines.

When choosing the machine, consider your expected growth, and not only your current demand.

Which Are The Main Steps Involved In The Operation Of Chocolate Filling Machine?

A chocolate filling machine operates using various principles to ensure that the filling of various products happens efficiently.

The main operational steps of a chocolate filling machine are as follows:


This step involves making sure all ingredients and materials you require for the chocolate filling process are available.

Also, ensure you have the shells that you will fill with the chocolate. Power up the machine once you ensure all parts are in good working condition.

Moving Ingredients

Once the machine is on, the chocolate ingredients will move to the hopper from the mass storage tanks. Also, shell moldings will move with the assistance of the conveyor systems from the storage area.

Make sure the hopper has the correct temperature to heat and maintain the chocolate in a molten state.

Filling Shells

Once the shells reach the filling area, the chocolate filling machine will perform the filling process. The filling nozzles will position themselves and direct the molten chocolate into the shells.

Also, the filling nozzles will control the chocolate quantity it fills in the shells. These nozzles are accurate enough to fill the shells while minimizing chocolate wastage.

Besides, the chocolate filling process happens not only on the shells but also on other products. The filling nozzles will use similar techniques to fill both the shells and other products with molten chocolate.


Once the machine completes the filling process, the products or filled shells move to the cooling tunnels via the conveyor system.

Besides, the control panel allows you to control the speed of the conveyor belt and the cooling temperature.

Also, the control panel allows you to remotely monitor the chocolate filling machine from a safe area.

Depending on how you want the product to be, you can cool the products to a semi-solid or solid state.

After the cooling process, monitor the quality of the final products and make sure they are as per the set specifications.

Make sure the final product has the correct quality when inspecting the quality. Once it passes this test, package, and store the products in the best conditions before transportation.

How Do You Troubleshoot Chocolate Filling Machine?

Troubleshooting allows you to identify an issue and solve it quickly. One of the main problems this machine may encounter is having inconsistent fills.

Here are some solutions to inconsistent fills:

Overflow Fillers

One possible issue comes about when you are setting up the machine. These fillers may need removal or adding spacers on every nozzle when altering between bottles.

Ensure the spacers are in the right position by making the necessary corrections. A bad seal can also cause inconstant fills, as bad seals can cause fill levels to deviate.

Also, make sure the machine has the correct air pressure on the pathway of the product.

Other Fillers

Piston, gravity, and pump fillers fill chocolate to a specific volume and not a level. One possible solution is to change the bottles you are using.

A change in the chocolate viscosity might cause this problem. This means you need to control the temperature of the molten chocolate as it affects how it will flow.

You can also change the fill times, that is, delay and duration time, to solve this issue.

Can You Integrate A Clean-In-Place (CIP) System With Chocolate Filling Machine?

Yes, this is possible. A clean-in-place allows you to input the cleaning parameters via the control panel.

This feature makes the process simple and quick and needs little to no disassembly, and requires less manual labor. Choosing to include a CIP may affect the solution for the chocolate filling machine.
