Condensed milk production Dairy lines
Condensed Milk Production Line Brief
1. Overview
A condensed milk production line is designed to transform raw milk or milk powder into concentrated milk products with a long shelf life. This process involves several stages, including standardization, pasteurization, evaporation, and packaging.
2. Key Components
- Raw Milk Reception: Fresh milk is transported from farms and stored in refrigerated tanks.
- Pasteurization: Milk is heated to 72-75°C for 15-20 seconds (HTST) or 135°C for a few seconds (UHT) to eliminate bacteria.
- Evaporation: Milk is concentrated to 30-40% solids using vacuum evaporators.
- Homogenization: Fat globules are broken down to improve texture and stability.
- Cooling and Crystallization: For sweetened condensed milk, lactose crystals are added and the mixture is cooled to induce crystallization.
- Packaging: The final product is filled into metal cans, aseptic cartons, or bottles.
3. Process Flow
1. Raw Milk Standardization**: Adjusting the fat and protein content.
2. Heat Treatment: Pasteurization to ensure safety.
3. Evaporation: Removing water to concentrate the milk.
4. Homogenization: Ensuring a smooth texture.
5. Cooling and Crystallization: For sweetened condensed milk, cooling to induce lactose crystallization.
6. Filling and Sealing: The product is filled into containers and vacuum-sealed.
4. End Products
- Sweetened Condensed Milk: Contains added sugar and has a syrupy consistency.
- Unsweetened Condensed Milk (Evaporated Milk): No sugar added, suitable for cooking and baking.
- Prepared Condensed Milk: With added ingredients or fortifiers for specific uses.
5. Capacity and Customization
- Capacity: From 2 tons/day to 300 tons/day.
- **Customization**: Lines can be tailored to produce various products and packaging types.
6. Benefits
- Efficiency: High production capacity with minimal waste.
- Quality: Advanced technology ensures consistent product quality.
- Flexibility: One line can produce multiple products, using either fresh milk or milk powder.
7. Equipment
- Evaporators: For water removal.
- Homogenizers: For texture improvement.
- Filling Machines: For accurate packaging.
- CIP Systems: For cleaning-in-place to maintain hygiene.
8. Future Trends
- Sustainability: Focus on energy efficiency and eco-friendly practices.
- Automation: Integration of IoT for real-time monitoring and optimization.
A condensed milk production line offers a comprehensive solution for producing high-quality, shelf-stable dairy products. With advanced technology and customization options, it meets the diverse needs of the dairy industry.

Customized solution for condensed milk production line
The Condensed Milk Processing Line is a specialized system designed for the production of various types of condensed milk, including sweetened condensed milk, light condensed milk, and prepared condensed milk. The customization of this processing line can be tailored to meet specific client requirements and production capacities.
1. Raw Material Selection
The processing line begins with the selection of raw materials, which may include fresh milk or milk powder. The choice between these two options depends on the desired end product and the operational capabilities of the facility.
2. Preheating and Sterilization
Once the raw materials are selected, they undergo preheating and sterilization. This step is crucial as it eliminates microorganisms that could spoil the product and helps in achieving the desired viscosity during storage. The typical temperature for heat treatment is between 100-120°C for about 60 seconds.
3. Sugar Addition
For sweetened condensed milk, sugar is added at this stage. There are two methods for adding sugar:
Dry sugar can be added before heat treatment.
Sugar syrup can be introduced during evaporation.
The concentration of sugar must reach at least 62.5% in the aqueous phase to ensure proper preservation through osmotic pressure.
4. Concentration Process
The mixture then moves to an evaporator where approximately 60% of the water content is removed under vacuum conditions at temperatures ranging from 60-70°C. This process thickens the milk into a viscous product suitable for further processing.
5. Cooling and Crystallization
After concentration, the product must be cooled rapidly while being agitated to control crystallization effectively. This step ensures that lactose precipitates as small crystals rather than large ones, which would make the final product gritty and undesirable.
6. Canning or Packaging
Once cooled, the condensed milk is filled into metal cans or other packaging options such as aseptic cartons or tubes. The packaging process must adhere to strict hygiene standards to maintain product quality over its shelf life, which can reach up to 18-24 months under ambient conditions.
7. Quality Control Systems
Throughout each stage of production, quality control measures are implemented to monitor parameters such as density, viscosity, and microbial load to ensure that all products meet food-grade standards.
8. Customization Options
The entire processing line can be customized based on:
Desired production capacity (ranging from 2 tons/day to 100 tons/day).
Specific formulations (e.g., varying sugar levels or additional nutritional fortifiers).
Equipment specifications (e.g., type of evaporator or filling machine).
This flexibility allows manufacturers to produce multiple types of condensed milk products using a single processing line efficiently.
