The process of making milk powder is a complex process that requires multiple steps and strict quality control. The following is a detailed introduction to the production process of milk powder.
1. Collect raw materials.
The first step in making milk powder is to collect raw materials, mainly including milk, soybeans, malt, etc. These raw materials need to be rigorously inspected and screened to ensure their quality and safety.
2. Mix raw materials.
The collected raw materials are mixed together in a certain proportion, which is determined according to the product requirements and market demand. The homogeneity and stability of the raw materials need to be guaranteed during the mixing process to ensure the quality of the final product.
3. Heating and concentration.
The mixed raw material is heated to a certain temperature so that the water in it evaporates, and the raw material is concentrated at the same time. This process removes excess moisture and impurities and increases the concentration of raw materials.
4. Spray drying.
The concentrated raw material is piped into a spray dryer, where it is sprayed into tiny droplets through a high-pressure nozzle and then dried. Spray drying can quickly remove moisture and improve the drying effect of raw materials, while ensuring the taste and nutritional value of the product.
5. Grinding and screening.
The dried raw materials are ground and sieved to remove the large particulate matter in them to obtain fine milk powder particles. In this process, attention needs to be paid to controlling the grinding strength and the accuracy of sieving to ensure the purity and quality of the product.
6. Packaging and storage.
The ground and sieved milk powder granules are packaged and stored. Packaging materials need to have the characteristics of good sealing, moisture-proof, anti-oxidation, etc., to ensure the shelf life and quality of the product. During storage, it is necessary to pay attention to controlling temperature and humidity, and conduct regular quality inspection and spot checks to ensure the safety and stability of the product.
In addition to the above six steps, the production of milk powder also needs to pay attention to the following points:
First of all, the raw materials used to make milk powder need to be safe and reliable, and be purchased and used in strict accordance with national laws, regulations and standardsSecondly, it is necessary to ensure the cleanliness and hygiene of the equipment during the production process to avoid contamination and cross-contaminationFinally, the milk powder produced needs to be inspected and spot-checked to ensure that it meets the relevant national standards and market demand.
In conclusion, the process of making milk powder is a complex and rigorous process that requires multiple steps and quality control. Only the safety and reliability of raw materials, and strict control of hygiene and quality standards in the production process can produce high-quality milk powder and escort the healthy growth of the baby.
