What Are The Major Parts Of Chocolate Grinding Machine?

Parts Of Chocolate Grinding Machine

Parts Of Chocolate Grinding Machine

There are several parts in a chocolate grinding machine.

These include:

Drum Lid

It is the part that covers the stainless steel drum during the chocolate grinding process.

Besides, it assists in containing the nibs and chocolate liquor from splashing off the stainless steel drum.

Top Lock Knob

This part will firmly secure the deflector blades, stone holder, and roller stones to the spindle of the drum.

It ensures the grinding operation happens smoothly by applying the correct pressure to these parts.

It also has a spring to ensure that these pieces securely lock before operation.

Stone Holder

It is the part on which you will attach the roller stones.

It ensures the roller stones are intact during the entire grinding process.

Roller Stones

These parts are responsible for the grinding of the nibs.

They are sturdy and provide pressure to the nibs as they rotate to grind them.

Bowl Heaters

These parts will increase the temperature of the stone rollers.

It does this to lower the time it takes to express fat from nibs.

Also, they decrease the time you need to process a batch of nibs and will also assist in rapidly evaporating unwanted volatiles.

Deflector Blades

These parts will prevent the chocolate items from sticking to the stainless steel drum.

It does this by scraping the chocolate thus enhancing the grinding of the nibs.

Stainless Steel Drum

This is the part at which the grinding process takes place.

Also, it assists in containing the chocolate liquor as the grinding proceeds from splattering.

Besides, it revolves as the grinding action takes place thus ensuring all nibs pass through the roller stones.


This is the part at which you will power on or off the machine.

Motor Unit

This component will provide convert the electrical power into mechanical power which drives the roller stones.

The motor unit can have a direct or indirect drive mechanism.

For a direct drive mechanism, you will connect the motor’s shaft directly to the drum spindle.

However, the indirect drive mechanism involves connecting the motor to the drum spindle by using a chain or belt.

Rubber Feet

This is a part that makes sure the machine does not move during operation.

Also, it offers sturdy support when the chocolate grinding machine lacks stands.


This is a part that the entire chocolate grinding machine rests on.

It gives the chocolate grinding machine sturdy support during the chocolate grinding process.

How Does Chocolate Grinder Machine Work?

The working process of this machine is straightforward.

Here are the steps on how this machine operates:

Preparation Stage

Begin the operation by assembling the machine and ensuring all parts are in good working condition.

Make sure the deflector blades are in the right alignment and the roller stones have the correct pressure.

Also, make sure all the ingredients you are using in the grinding process are in ample quantity.

For instance, when grinding chocolate, ensure you have the cocoa nibs ready.

Other ingredients include sugar and cocoa butter.

Applying The Ingredients

Before placing the ingredients in the machine, ensure that the machine is warm enough.

Load the ingredients gradually in the machine as this ensures that the stones do not stop.

If the stones stop, this will inhibit the chocolate grinding machine from spinning.

Also, you can add more nibs once you notice that the paste has a chunky peanut butter consistency.

Besides, loading the drum quickly will lower the speed of the production or cause the machine to struggle.

If you notice the machine is struggling, do not add more ingredients but let it refine the ones in the drum for a while.

Grinding Process

The machine will now grind the nibs and thereby changing the consistency of the nibs.

As the roller stones apply pressure and heat, the nibs will start to turn into a paste.

Also, you can add cocoa butter during the grinding process to glisten the chocolate liquor.

This happens as the mixture is refining and warming up.

Also, you can add other ingredients such as sugar and milk powder.

Besides, always add flavors when the refining process is almost ending.

This is to prevent some flavor from disappearing during the conching process.

Emptying The Drum

Once the chocolate has the right consistency, texture, and flavor, you will shut off the machine.

Remove the chocolate liquor and then you can begin a new process, or clean the machine and store it.

Besides, you should not store the chocolate or other items in the stainless steel drum.

Why Is Heat Necessary During The Operation Of Chocolate Grinding Machine?

Applying heat as you are conducting the chocolate grinding process is a vital factor.

Heat will lower the time you need to express fat from the chocolate nibs.

It will also melt the cocoa butter and convert nibs into a paste then to a thick chocolate liquor quickly.

Besides, it will also speed up the chocolate grinding process and vaporize all unwanted volatile substances.

In other applications, you can apply heat by using a heat gun or a hairdryer.

However, make sure the drum does not get too hot as it may burn the chocolate or cause the machine to damage.

Make sure the bowl has a warm and not hot temperature.

What Is The Production Capacity Of Chocolate Grinder Machine?
