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.
Step 1: Raw material preparation
Oil melting tank
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.
| Model | TZ-200 | TZ-500 | TZ-1000 | TZ-1500 |
|---|---|---|---|---|
| Capacity | 200 L | 500 L | 1,000 L | 1,500 L |
| Heating Power | 6 kW | 12 kW | 24 kW | 24 kW |
| Material | 304 stainless steel | 304 stainless steel | 304 stainless steel | 304 stainless steel |
| Overall Dimensions | 1200 × 1450 × 1500 mm | 1600 × 1450 × 1500 mm | 3210 × 1450 × 1500 mm | 3910 × 1450 × 1500 mm |
| Weight | 360 kg | 560 kg | 860 kg | 1,250 kg |
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.
| Model | TZ-420 | TZ-560 |
|---|---|---|
| Output | 500 kg/h | 1,000 kg/h |
| Power | 8.5 kW | 16.5 kW |
| Powder Fineness | 50–120 mesh | 50–120 mesh |
| Overall Dimensions | 2000 × 1600 × 2100 mm | 2500 × 2000 × 2400 mm |
| Weight | 650 kg | 900 kg |
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
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.
| Parameter | TZ-500 | TZ-1,000 | TZ-1,500 |
|---|---|---|---|
| Capacity | 500 L | 1,000 L | 1,500 L |
| Output | 500 kg/h | 1,000 kg/h | 1,500 kg/h |
| Grinding Fineness | 18–22 μm | 18–22 μm | 18–22 μm |
| Grinding Ball Weight | 750 kg | 1,000 kg | 1,300 kg |
| Motor Power | 37 kW | 55 kW | 75 kW |
| Packaging Size | 900 × 1800 × 2800 mm | 1000 × 2000 × 3100 mm | 1000 × 2000 × 3100 mm |
| Weight | 4,100 kg | 4,900 kg | 5,200 kg |
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
Chocolate heating 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.
| Model | TZ-60 | TZ-100 | TZ-200 | TZ-300 | TZ-500 | TZ-1,000 | TZ-2,000 L |
|---|---|---|---|---|---|---|---|
| Capacity | 60 L | 100 L | 200 L | 300 L | 500 L | 1,000 L | 2,000 L |
| Heating Power | 3 kW | 3 kW | 3 kW | 6 kW | 6 kW | 12 kW | 12 kW |
| Material | 304 stainless steel | 304 stainless steel | 304 stainless steel | 304 stainless steel | 304 stainless steel | 304 stainless steel | 304 stainless steel |
| Stirring Power | 0.55 kW | 0.55 kW | 0.75 kW | 1.1 kW | 1.5 kW | 1.5 kW | 3 kW |
| Rotational Speed | 24 rpm | 24 rpm | 24 rpm | 24 rpm | 24 rpm | 24 rpm | 24 rpm |
| Overall Dimensions | 900 × 750 × 1000 mm | 900 × 750 × 1200 mm | 1150 × 900 × 1300 mm | 1250 × 1000 × 1550 mm | 1350 × 1100 × 1650 mm | 1650 × 1350 × 1900 mm | 1900 × 1650 × 2250 mm |
Step 4: Continuous chocolate tempering
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.
| Model | TZ-250 | TZ-500 | TZ-1,000 |
|---|---|---|---|
| Capacity | 250 L | 500 L | 1,000 L |
| Output | 250 kg/h | 500 kg/h | 1,000 kg/h |
| Main Motor Power | 2.5 kW | 3 kW | 4 kW |
| Electric Heating Power | 5 × 4 kW | 5 × 4 kW | 5 × 4 kW |
| Proportional Valve | Siemens | Siemens | Siemens |
| Control System | Delta/Siemens | Delta/Siemens | Delta/Siemens |
| Water Pump | Grundfos | Grundfos | Grundfos |
| Ice Water Machine | 5 HP | 10 HP | 15 HP |
Step 5: Chocolate depositing and sprinkling
Double-head chocolate depositing and sprinkling machine
The tempered chocolate is finally transferred to the depositing and sprinkling machine. This machine combines chocolate depositing with automatic topping, allowing manufacturers to produce both standard molded chocolate and decorated chocolate products.
The machine can be configured with different numbers of depositing heads according to the product and production requirements.
| Model | TZ-320 | TZ-510 |
|---|---|---|
| Production Capacity | 80–300 kg/h | 100–400 kg/h |
| Production Cycle Time | 15–25 times/min | 15–25 times/min |
| Mold Size | 320 × 200 × 30 mm | 510 × 200 × 30 mm |
| Mold Quantity | 280–380 pcs | 280–380 pcs |
| Compressor | 15 HP | 20 HP |
| Compressed Air Volume | 0.3 m³/h | 0.3 m³/h |
| Total Power | 21 kW | 23 kW |
| Weight | 4,800 kg | 5,800 kg |
| Chocolate Filling Rate | <65% | <65% |
| Other Filling Rate | <55% | <55% |
| Mixed Nut Diameter | <5 mm | <5 mm |
| Filled Nut Diameter | <1 mm | <1 mm |
| Mobile Depositing Head | Optional | Optional |
| Depositing Heads | 1 / 2 / 3 / 4 optional | 1 / 2 / 3 / 4 optional |
