Complete milk processing line and dairy factory equipment
A complete milk processing production line covers the entire process from receiving, storing, pre-processing, processing, packaging of raw milk to the final product. The following is a detailed introduction to each main link:
1. Raw milk receiving and inspection
1.1 Reception
Vehicle inspection: Check the milk transportation vehicles to ensure that there is no pollution during transportation.
Sample collection: Collect samples from each batch of raw milk for quality testing.
1.2 Inspection
Quality testing: including the detection of indicators such as total bacterial count, antibiotic residue, fat content, protein content, etc.
• Non conforming processing: For raw milk that does not meet the standards, return or special processing will be carried out.
2. Raw milk storage
2.1 Refrigeration
• Refrigerated tank: Store qualified raw milk in a refrigerated tank at a low temperature (usually around 4 ° C) to prevent bacterial growth.
• Temperature monitoring: Real time monitoring of the temperature of the refrigerated container to ensure a constant temperature.
3. Preprocessing
3.1 Filtration and Purification
• Coarse filtration: removes large particles and impurities from raw milk.
• Fine filtration: further purification through microporous membrane.
3.2 Standardization
• Fat adjustment: Adjust the fat content of raw milk according to product requirements.
Protein adjustment: Adjust protein content if necessary.
3.3 Homogenization
Homogenizer: By using high pressure to crush fat balls, the fat is evenly distributed, improving the taste and stability of the product.
3.4 Sterilization
Pasteurization: kills most harmful microorganisms by heating (63-65 ° C, 30 minutes or 72-75 ° C, 15 seconds).
Ultra high temperature sterilization (UHT): Thoroughly sterilize the product at a higher temperature (135-140 ° C, 4 seconds), allowing it to be stored at room temperature for a long time.
4. Processing
4.1 Fermented dairy products
Fermentation tank: Transfer the pre treated milk into the fermentation tank and add lactic acid bacteria for fermentation.
• Cooling: After fermentation is complete, cool the fermented milk to a suitable temperature to prevent excessive fermentation.
• Packaging: Fill the cooled fermented milk into a cup or bottle and seal it for packaging.
4.2 Cheese
• Solidification: Add a coagulant (such as lactase) to the pre treated milk to make it coagulate.
• Cutting: Cut the solidified cheese into small pieces to promote whey separation.
• Drainage: Drain the whey and retain the cheese chunks.
• Molding: Press the cheese chunks into shape.
Maturity: Place the formed cheese in a specific environment to mature and enhance its flavor.
4.3 Milk powder
• Concentration: By evaporating, a portion of the water in milk is removed to reduce its moisture content.
• spray drying: pass the concentrated milk through the spray drying tower to form fine powder particles.
• Cooling: cool the dried milk powder after spray drying to prevent caking.
• Packaging: Fill the cooled milk powder into bags or cans and seal them for packaging.
5. Packaging
5.1 Filling
Aseptic filling: Fill the product into a packaging container under sterile conditions to ensure the hygiene and safety of the product.
Sealing: Seal the packaging container to prevent air from entering.
5.2 Labels and Stacking
Label printing: Print product information, production date, shelf life, etc. on the packaging.
• Stacking: Stack the packaged products and prepare them for transportation.
6. Storage and transportation
6.1 Refrigerated storage
• Refrigerated warehouse: Store finished products in a refrigerated warehouse and maintain a suitable temperature (usually around 4 ° C).
• Temperature monitoring: Real time monitoring of the temperature in the refrigerated warehouse to ensure a constant temperature.
6.2 Transportation
• Refrigerated truck: Use a refrigerated truck for transportation to ensure that the product remains at a low temperature during transportation.
Temperature monitoring: Real time monitoring of temperature during transportation to ensure product quality.
Success factors
