Fully Automatic Infant Formula Milk Powder Filling Machine Online Weighing Vacuum Can Sealing Integrated Dairy Packaging Line
Shouda fully automatic milk powder tin can filling production line is specially developed for large-scale dust-free mass production of dairy and nutritional powder. It solves core industry defects of traditional filling machines including powder flying, unstable metering, high internal oxygen causing oxidation, air leakage sealing and complicated format changeover. The line realizes unmanned automatic operation covering empty can sorting, dust cleaning, powder filling, vibration settling, weight recheck, vacuum nitrogen sealing, traceability coding, labeling and cap pressing, fully matching strict production standards for infant formula milk powder. Equipped with dual independent servo two-stage screw filling system, large screw completes fast coarse filling while tiny screw carries out micro weight supplement. A bottom vibration station compacts fluffy milk powder evenly. The rear online dynamic checkweigher feeds back weight data to adjust screw rotation speed in real time, drastically reducing unqualified overweight & underweight cans with superior accuracy than single-head fillers. The whole filling chamber adopts fully closed negative pressure dust suction structure to eliminate powder overflow, reduce raw material waste and daily workshop cleaning cost. The core sealing unit integrates vacuum pumping and nitrogen flushing modules. It first extracts air inside cans under negative pressure, then injects 99.99% high-purity nitrogen to displace oxygen, stably controlling residual oxygen ≤3% inside cans. This technology well retains milk powder nutrition and flavor and extends shelf life effectively. Double seam sealing rollers are made of wear-resistant SUS304 stainless steel, forming tight leak-proof seams without can burst or moisture caking. All powder contact components adopt seamless mirror stainless steel without sanitary dead corners. Filling screws, hoppers and feeding bins can be quickly detached and rinsed without tools; optional CIP cleaning module supports automatic pipeline circulation cleaning, complying with hygiene control standards of GMP clean workshops. The touch screen stores multiple powder product formulas, switching different weights and can types only needs one-click parameter recall without mold replacement, completing format change within 3 minutes for flexible multi-product small-batch production. The machine runs stably with low noise and anti-vibration design, supporting 24-hour non-stop continuous operation. Multiple photoelectric sensors monitor abnormal conditions including empty cans, powder shortage, can jamming and poor sealing, triggering auto stop, sound-light alarm and automatic rejection of defective cans to cut production loss. The whole line adopts modular spliced layout with compact footprint. It can work separately or link with rear case packing & palletizing equipment to build an integrated intelligent packaging workshop, serving as core complete set equipment for dairy factories and nutritional powder manufacturers upgrading standardized production.
FAQ
Q1: Is this production line suitable for infant formula? Can it meet dust-free GMP clean workshop standards?
A: It is perfectly applicable to high-grade powder such as infant formula. The whole machine features closed negative pressure dust suppression, SUS316L powder contact parts, compatible with Class 10,000 purification workshops. The full process avoids manual powder contact to eliminate cross-contamination and fully complies with GMP & HACCP food regulations.
Q2: Milk powder is fluffy and easy to produce dust; will dust pollute the workshop and waste raw materials during filling?
A: The whole line is equipped with integrated negative pressure dust removal system with fully enclosed filling chamber to prevent dust overflow. The matched dust recovery hopper collects fine powder for reuse, cutting raw material loss by over 90% and greatly reducing daily workshop cleaning work.
Q3: What residual oxygen level can be achieved after vacuum nitrogen flushing? How much shelf life improvement can it bring?
A: Standard configuration stabilizes residual oxygen ≤3% inside cans; upgraded version reaches ≤0.3%. Isolating oxygen inhibits fat oxidation and nutrition loss of milk powder, extending shelf life by over 30% compared with ordinary non-nitrogen filled cans, avoiding caking and rancidity.
Q4: Is format change complicated for different weights and sizes of milk powder tins? Does mold replacement required?
A: No mold replacement needed. Can height limit, filling screw volume and nitrogen flushing duration are all digitally adjusted on touch screen. Over 20 preset formulas are stored for quick switching between camel milk powder, infant formula, whey protein powder within 3 minutes.
Q5: How stable is filling accuracy? Will batch weight deviation occur during mass continuous production?
A: Dual servo screw plus closed-loop online weighing correction system controls error within ±1g for cans under 500g and ≤±5g for 1000g large tins. The machine dynamically compensates powder density fluctuation in real time to guarantee uniform weight of whole batches with rare mass deviation.
Q6: Is daily cleaning and maintenance complicated? Is milk powder residue easy to remove?
A: Hopper, filling screw and feeding bin adopt tool-free quick-disassembly modular design for simple water washing. Optional CIP online cleaning module enables automatic pipeline circulation cleaning without milk powder residue breeding bacteria. Routine maintenance only requires regular lubrication of transmission parts.
Q7: Can the machine automatically detect air leakage or uneven seams after can sealing? What causes poor sealing?
A: Residual oxygen detector & sealing pre-judgment sensors are installed at sealing station to automatically divert and reject leaky or defective seam cans. The machine triggers alarms for roller abrasion, deformed cans or abnormal nitrogen pressure to block defective products in advance.
Q8: Can this filling line fully link with the side push case packer mentioned before for full unmanned operation?
A: Complete signal linkage is supported. Finished sealed cans are conveyed to side push packing station automatically, synchronized line speed adjustment with auto slowdown/stop of filling front end if cans run short, unified fault alarm logic for full unmanned workflow from filling to case packing.
Q9: What basic workshop conditions of power, air and nitrogen does the production line require?
A: Standard 380V three-phase industrial power supply, stable air compressor air source of 0.6–0.9MPa; nitrogen purity ≥99.99% with 0.4MPa steady pressure. No special workshop reconstruction required for installation and production.
Q10: What after-sales services are covered after purchase? Do you provide on-site installation and operator training?
A: Full machine warranty and free pre-delivery machine testing are included. Services cover on-site installation & commissioning, full-process operator training, real-time remote fault troubleshooting, lifelong technical consultation, and long-term supply of wearing parts like screws & seals at factory cost price.
