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.

Yogurt Processing Line Equipment Benefits

Automated Cleaning

The in-situ cleaning system cleans tanks, pipes, and equipment without manual disassembly. This process maintains hygiene and prevents microbial contamination.

Production Capacity

The system supports a 500-liter production capacity, and manufacturers can adjust the equipment to handle larger production volumes or different product lines.

Fermentation

The fermentation tanks have controlled temperatures. Whether it’s stirred, set, or flavored yogurt, the system ensures consistent acidity, consistency, and flavor.

Quality

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