Milk Powder Processing Line

A Milk Powder Processing Line is a combination of equipment and production technology that processes liquid milk, goat milk or other dairy products into milk powder. The Milk Powder Processing Line process of milk powder usually includes a series of steps such as concentration, spray drying, cooling, and packaging. The purpose of the Milk Powder Processing Line is to convert raw materials into final products efficiently and hygienically, ensuring product quality, nutrition and safety.

Main Features:

1. Efficient automation: Reduce manual intervention, improve production efficiency, and reduce costs.

2. Quality Assurance: Precisely control the production process to ensure stable milk powder quality.

3. Health & Safety: Meet strict health standards and reduce contamination risks.

4. Save resources: Optimize the use of raw materials and reduce energy consumption and waste.

5. Flexible adaptation: Milk Powder Processing Line can produce a variety of varieties to meet market demand.

6. High productivity: Support large-scale production and adapt to market growth.

>> Classification Of Milk Powder

1.Whole milk powder (fat>26%): a powdery product made from milk only, with or without the addition of food additives and food nutrition fortifiers, concentrated and dried.

2. Partially skimmed milk powder (fat 1.5-26%): a powdery product made from milk only, with or without the addition of food additives and food nutrition enhancers, removing part of the fat, concentrated and dried.

3. Skimmed milk powder (fat<1.5%): A powdery product made from milk only, with or without the addition of food additives and food nutrition fortifiers, by removing fat, concentrating and drying.

4. Full-fat sweetened milk powder (fat>20%): a powdery product made from milk and white sugar as raw materials, with or without the addition of food additives and food nutrition fortifiers, concentrated and dried.

5. Flavored milk powder: A powdery product with a milk solid content of not less than 70% that is made from milk as the main raw material, with the addition of auxiliary materials, with or without the addition of food additives and nutritional fortifiers, through concentration and drying (or dry mixing)

Milk Powder Processing Line production process

1. Raw material reception and preprocessing

Process:

Raw material receiving: receiving fresh milk or other dairy products.

Quality testing: Conduct quality testing on milk, such as composition analysis, bacterial testing, etc., to ensure that raw materials meet production standards.

Filtration: Impurities are removed by filtration.

Equipment:

Milk filter: used to filter impurities in raw milk.

Milk sterilization equipment (pasteurizer/UHT sterilization equipment): Use pasteurization (low temperature for a long time) or ultra-high temperature instant sterilization (UHT) to kill bacteria in milk and ensure milk hygiene.

2. Concentrate

Process:

Emulsification and concentration: By removing part of the water, the liquid milk is concentrated to a certain solid concentration to improve the efficiency of subsequent drying.

Equipment:

Evaporator: Heats liquid milk, removes part of the water, and obtains concentrated emulsion.

Membrane separation equipment: used to separate and concentrate the water in milk through reverse osmosis or nanofiltration technology to maintain nutrients.

3. Spray drying

Process:

Spray drying: Spray concentrated milk into fine droplets, and the water quickly evaporates in the high-temperature air flow, eventually forming milk powder.

Equipment:

Spray tower: The concentrated emulsion is sprayed into fine droplets through the spray system, and the water is quickly evaporated by the hot air to form milk powder.

Hot air system: Provides the hot air required for spray drying, usually heated by natural gas or steam.

4. Cooling and screening

Process:

Cooling: Cool the milk powder to room temperature to prevent excessive temperature from affecting the quality.

Screening: Screen out the particles that are not completely dried to ensure uniform milk powder particles.

Equipment:

Cooler: used to quickly lower the temperature of milk powder to avoid agglomeration or loss of nutrients due to excessive temperature.

Screening machine: Screen out large particles or unqualified particles to ensure the uniformity and fineness of milk powder.

5. Packaging

Process:

Measurement: Measure the cooled milk powder according to the set weight.

Packaging: Put milk powder into bags, cans, boxes and other containers and seal them.

Equipment:

Measuring device: Accurately measures the weight of milk powder to ensure the same quantity in each package.

Automatic packaging machine: Put milk powder into packaging bags or cans, and perform operations such as sealing, labeling, and coding.

Vacuum packaging machine: Vacuum packaging of milk powder to ensure safe storage and long-term shelf life of the product.
