The chocolate production line is designed to process cocoa liquor, cocoa butter, compound chocolate, sugar, cocoa powder, milk powder, and other chocolate ingredients into molded chocolate products.

Our chocolate depositing production line covers sugar powder preparation, cocoa butter melting, fine grinding, temperature holding, tempering, and automatic depositing and sprinkling. With production capacities from about 80 kg/h to 1,500 kg/h depending on the selected equipment configuration, the line can produce solid, filled, layered, shaped, and decorated chocolate products.

Process flow of chocolate production line

The complete process can be understood as:

Raw materials → Oil melting and sugar powder preparation → Mixing → Fine grinding → Temperature holding → Tempering → Depositing and sprinkling

The workflow described above represents the standard configuration; however, we can also configure cooling, demolding, and packaging equipment to meet specific customer requirements.

Шаг 1: Подготовка сырья

Oil melting tank

Melting machine

The oil melting tank is used to prepare cocoa-based ingredients that require controlled heating before mixing and grinding. It can be used for cocoa liquor, cocoa butter, compound chocolate, and other suitable chocolate materials.

The tank is manufactured from 304 stainless steel and is available in several capacities.

Sugar grinding machine

Sugar grinding machine

While the chocolate-based ingredients are being melted, white sugar is processed separately.

The sugar grinder machine converts sugar into a fine powder before it is added to the chocolate formulation.

Step 2: Mixing and chocolate fine grinding

The second step of the chocolate production line is mixing and fine grinding. After the front-end ingredients have been prepared, the melted chocolate ingredients, sugar powder, and other recipe components are combined. The mixture then enters the ball mill.

Chocolate ball mill

Chocolate ball mill machine

The chocolate ball mill machine is the main refining equipment in the chocolate production line.

It grinds the mixed chocolate mass to a fine and uniform particle size before the chocolate enters the holding and tempering stages.

Fine grinding is important because the particle size of the chocolate mass has a direct effect on its texture. The refining stage prepares a more uniform chocolate mass for subsequent temperature control and molding.

Step 3: Chocolate holding and stirring

Heat preservation tank

After grinding, the chocolate mass is transferred to the holding tank. This stage provides temperature-controlled storage and continuous stirring before tempering.

The holding tank helps maintain the chocolate in a stable processing condition and reduces the risk of solidification or separation during continuous production.

Step 4: Continuous chocolate tempering

Tempering tank

Before chocolate is deposited into molds, it needs to pass through the tempering process. The continuous tempering machine controls the chocolate temperature and prepares the chocolate for stable molding.

This step is a critical stage in the chocolate production line.
