[0023] Through a double verification mechanism, we review the supplier's business license and production license qualification documents to ensure that they have the legal and compliant production and operation capabilities; we also conduct a detailed comparison of the physical, chemical, and microbiological core indicators in the manufacturer's product batch inspection report to eliminate the risks of excessive pesticide residues and microbial contamination, ensure the quality of raw materials from the source, and lay a solid foundation for the high-quality production of formula milk powder.

[0024] Among them, the material collection in S2 refers to the collection of qualified raw and auxiliary materials from the warehouse. The operator must strictly follow the addition amount specified in the formula operation instructions and use an electronic scale that has passed the inspection and is within the validity period for accurate weighing. A two-person review system is implemented during the weighing process to ensure that the quantity of each material used is accurate, ensure the accuracy of the product formula ratio, and provide a reliable material basis for subsequent production.

[0025] A two-person review system is implemented, with one person performing the weighing operation while the other person simultaneously checks the material name, specifications, and dosage to ensure that the weighed value is exactly the same as the formula. High-precision material retrieval ensures the accuracy of the product formula and lays a solid foundation for subsequent production processes.

[0026] Among them, the unpacking and outer packaging in S3 refers to the transfer of raw and auxiliary materials to a quasi-clean operation area, removing their outer packaging in this area, and handling them with care to avoid the scattering of dust, impurities and pollutants attached to the surface of the outer packaging. The inner bag materials after unpacking are sealed in time and transferred to the next process through a dedicated channel, effectively reducing the risk of pollution of the production environment.

[0027] Operators remove outer packaging with standardized and gentle techniques to avoid the spread of dust and impurities caused by rough operation. The inner bag materials are immediately sealed after unpacking and quickly transported through a dedicated channel to isolate potential pollution sources, effectively reducing the probability of pollution in the production environment and creating clean and safe production conditions for subsequent processes.

[0028] Among them, the cleaning of the inner packaging bag in S4 refers to using a special towel soaked in 75% concentration alcohol to wipe the surface of the inner bag thoroughly, and the wiping process should be done without dead corners. The bactericidal properties of alcohol are used to effectively kill bacteria and microorganisms that may exist on the surface of the inner bag.

[0031] In the sterilization stage of the inner packaging of raw and auxiliary materials, a two-pronged approach of process disinfection + equipment maintenance is adopted. Through the synergistic sterilization technology of ultraviolet rays and hot air, it is ensured that the materials are continuously sterilized in the tunnel for no less than 30 seconds, achieving efficient inactivation of bacteria and microorganisms, and ensuring that the inner packaging is clean and meets the standards; at the same time, a monitoring mechanism for the usage time of ultraviolet lamps is established. When the cumulative usage reaches 2000 hours, the lamp tube is replaced to stabilize the sterilization intensity. The full-cycle maintenance of the equipment is used to ensure the long-term sterilization efficiency and build a solid line of defense for production cleanliness.

[0032] The specific steps of premixing in S6 are as follows: Step 1: Accurately feed and mix materials, and standardize the operating procedures: Add the premix and other materials to the feeding station in sequence, and transfer them to the mixer through the conveying system. According to the material characteristics and product standards, strictly control the mixing time within 5-30 minutes, and the maximum single mixing volume does not exceed 500kg to ensure that the materials are fully stirred and evenly blended; Step 2: Real-time sampling and testing to ensure mixing quality: During the mixing process, use the equipment's built-in sampling port to regularly take samples to test the uniformity of material mixing. Once it is found that the mixing effect does not meet the standards, adjust the mixing time or parameters in time to ensure consistent distribution of product ingredients and effectively improve the overall quality of the formula milk powder.

[0033] The premix and raw materials are accurately put into the mixer, and the mixing time of 5-30 minutes and the maximum mixing volume of 500kg are strictly controlled to ensure sufficient mixing. At the same time, regular spot checks are carried out through the equipment sampling port to monitor the mixing uniformity in real time. If any problems are found, the parameters are adjusted immediately to improve product uniformity and quality stability through full-process quality control.

During the mixing process, regular inspections are carried out through the equipment's built-in sampling port to monitor the mixing uniformity in real time to ensure that all ingredients are fully blended and evenly distributed, thereby improving the quality and stability of the formula milk powder in all aspects.

[0038] The specific steps of the S9 gold inspection are as follows: Step 1: Calibration and maintenance of metal detection equipment: Before, during and after production, the sensitivity of the metal detector must be strictly tested according to the standards of ∮Fe1.0 for ferrous metals, ∮NFe1.2 for non-ferrous metals, and ∮SUS2.0 for stainless steel to ensure that the equipment is in the best detection state and provide reliable protection for metal foreign body detection; Step 2: Product metal foreign body detection and processing: Formulated milk powder is inspected for metal foreign bodies through a metal detector. Once the equipment detects metal foreign bodies, it will automatically alarm and reject unqualified products, effectively intercepting products with safety hazards and preventing them from flowing into the next production link.

[0039] A dual-track guarantee system of equipment calibration + product testing is adopted. Before, during and after production, the sensitivity of the metal detector is calibrated in multiple time periods in strict accordance with the standards of ∮Fe1.0 (ferrous metal), ∮NFe1.2 (non-ferrous metal) and ∮SUS2.0 (stainless steel metal) to ensure that the equipment always maintains the best detection accuracy. When the formulated milk powder passes through the metal detector, once metal foreign matter is found, the equipment will immediately and automatically alarm and accurately remove the problematic products, eliminating safety hazards and building a solid line of defense for product quality and safety.

[0040] With precision and adaptability as the core, we use high-precision filling machines to quantitatively fill according to product specifications, and strictly control the weight error of each bag within the standard range. According to customer needs, we flexibly use nitrogen-filled packaging to isolate oxygen and extend the shelf life, or conventional packaging to meet low storage requirements. After packaging, we undergo a double inspection of sealing and appearance, and only qualified products are put into storage to ensure quality and delivery standards.
