Yogurt Making Equipment Production Process
- Raw Materials: Operators load milk, milk powder, sugar, and other ingredients into the yogurt processor.
- Preheating: The system mixes the ingredients thoroughly and heats them to the optimal temperature.
- Pasteurization: The milk is heated to kill bacteria and denature the proteins.
- Cooling and Inoculation: The system cools the pasteurized milk to the fermentation temperature and then adds the starter culture.
- Fermentation: By controlling the fermentation time, the yogurt develops its texture and flavor.
- Stirring and Cooling: The stirred yogurt is mixed and cooled to stop fermentation.
- Transportation: The yogurt pump transfers the yogurt to the filling machine.
- Filling: The final product is hygienically packaged.

Yogurt Processing Line Equipment
Cooling Tank
- Function: Stores and pre-cools raw milk.
- Details: This tank receives fresh or reconstituted milk and rapidly cools it to approximately 4°C. Maintaining a low temperature inhibits microbial growth, ensuring freshness and high quality before entering the production line.
| Material | Power Supply | Total Power | Cooling Capacity | Thermal Insulation Performance | Compressor Power | Stirring Speed | Insulation Layer | External Dimensions |
|---|---|---|---|---|---|---|---|---|
| SUS304 | 380V/50Hz | 3 kW | 5322 W/hour | ≤1℃/3H | 3 P | 33 RPM | Polyurethane foam / 60mm | 2000×1500×1500 mm |
Filter
- Function: Removes impurities from milk.
- Details: Before entering the pretreatment system, milk undergoes multiple filtration processes, including double-layer filters used in large-scale production. These filters remove hair, feed particles, dust, and other fine solid impurities, ensuring a clean feed.
| Filtration capacity | Applicable temperature | Filter mesh size | Working pressure | Filter material | Filtration precision |
|---|---|---|---|---|---|
| 3 t/h | ≤120℃ | 200 mesh | ≤0.2 MPa | 304 stainless steel | 200 (mesh/in) |

Preheating Tank
- Function: Heating and blending.
- Details: The preheating tank heats the filtered milk to 50-60°C, creating the ideal condition for homogenization. During this stage, operators add sugar, stabilizers, and milk powder according to the product formula and mix them thoroughly to balance the fat and protein content for consistent product quality.
| Material | Power Supply | Stirring Motor Power | Stirring Speed | Electric Heating Power | Internal Diameter of Tank | Internal Height of Tank | Installation Dimensions (L×W×H) |
|---|---|---|---|---|---|---|---|
| SUS304 | 380V/50Hz | 0.37 kW | 36 r/min | 12 kW × 2 | 900 mm | 850 mm | 1300 × 1000 × 1850 mm |
Homogenizer
- Function: Breaks down fat globules, preventing fat from rising to the surface.
- Details: Under high pressure, milk is squeezed through narrow gaps, breaking down larger fat globules into smaller ones. This improves the final consistency and texture of the yogurt.
| Material | Power Supply | Production Capacity | Maximum Pressure | Work Pressure | Motor Power | External Dimensions (L×W×H) |
|---|---|---|---|---|---|---|
| SUS304 | 380V/50Hz | 1000 L/H | 25 MPa | 20 MPa | 7.5 kW | 1010 × 616 × 975 mm |
Pasteurization Tank
- Function: Kills pathogenic and putrefactive bacteria, and inactivates enzymes.
- Details: Heat milk to 90-95°C for 5-10 minutes. This process eliminates harmful microorganisms, inactivates natural enzymes, and denatures whey proteins. It creates a pure growth environment for fermentation bacteria.
| Material | Power Supply | Stirring Motor Power | Stirring Speed | Electric Heating Power | Internal Diameter of Tank | Material Inlet | Installation Dimensions (L×W×H) |
|---|---|---|---|---|---|---|---|
| SUS304 | 380V/50Hz | 0.37 kW | 36 r/min | 12 kW × 2 | 900 mm | φ38 mm | 1300 × 1000 × 1850 mm |


Fermentation Tank
- Function: Formation of yogurt and flavor.
- Details: Milk cooled to 42-43°C is inoculated with lactic acid bacteria, such as Lactobacillus bulgaricus and Streptococcus thermophilus. Fermentation takes 8-10 hours. The lactic acid bacteria break down lactose into lactic acid, thickening the milk into a gel-like texture.
| Power Supply | Stirring Speed | Electric Heating Power | Internal Diameter of Tank | Internal Height of Tank | Configuration | Installation Dimensions (L×W×H) |
|---|---|---|---|---|---|---|
| 380V/50Hz | 36 r/min | 12 kW × 2 | 900 mm | 850 mm | Stirring, cleaning ball, temperature display, feed inlet, breather, sight glass, manhole, insulation layer | 1300 × 1000 × 1850 mm |
Filling Machine
- Function: Packaging yogurt.
- Details: After fermentation, the conveying system transfers the yogurt to the filling machine, and the machine fills the product into bottles, cups, or other containers before sealing and labeling them.
| Power Supply | Power | Bag Length | Bag Width | Membrane Width | Bag Capacity | Equipment Dimensions | Machine Weight | Sealing Method |
|---|---|---|---|---|---|---|---|---|
| 380V/50Hz | 2.5 kW | 50-150 mm | 65-150 mm | 130-380 mm | 200-1050 ml | 1050×850×2050 mm | 370 kg | Back seal |
CIP Cleaning Machine
- Function: Automatic equipment cleaning.
- Details: CIP stands for “Cleaning in Place,” allowing for internal cleaning without disassembly. It uses circulating hot water, acid, and alkaline solutions to clean tanks and pipelines, removing residues and disinfecting the system.

Through standardized preheating, homogenization, and pasteurization processes, the yogurt maintains a uniform consistency and a longer shelf life.


FAQ
Pasteurization is performed at 62-65℃ for 30 minutes, or 72-75℃ for 15-30 seconds. This method requires refrigeration and has a shelf life of approximately 7 days. It is suitable for fresh milk, fresh yogurt, and fresh cheese. High-temperature instant sterilization, temperature 85-95℃, 15-30 seconds. Must be refrigerated, shelf life 7-21 days. Suitable for premium fresh milk, refrigerated yogurt, and cream. Ultra-high temperature (UHT) sterilization is performed at 135-140℃ for 3-5 seconds. Store at room temperature for 3-6 months. Suitable for room-temperature milk, yogurt suitable for long-distance transport, and plant-based milk.
This production line is semi-automatic, requiring manual operation of valves and pumps, and the equipment has adjustable temperature and time.
Yogurt fermentation takes approximately 8 hours, with pre-processing taking about 2 hours. The yield depends on the capacity of the fermentation tank. For example, a 500L fermentation tank will produce 500L of yogurt after 8 hours of fermentation. If you require a larger production volume, you can configure multiple fermentation tanks.
