4. Core Food-Grade Design Advantages For Milk & Whey Powder

4.1 High-Precision Servo Auger Metering System

Whey protein and milk powder are ultra-fine fluffy powders with poor fluidity; the machine adopts dual servo auger metering structure, the main large auger completes 90% fast filling, and the small fine-tuning auger supplements the remaining weight to ensure high consistency of finished product net weight. Weight error range: 10–100g small sachet ±0.1g; 100g–2kg medium/large pouch ±0.3g; canned 800g–5kg ±0.5g, meeting national food label weighing standards and avoiding customer complaints about inconsistent net content.

4.2 Dust-Proof, Deaeration & Nitrogen Flush Freshness Protection

Milk powder and whey protein contain a large amount of unsaturated fatty acids, which are easy to oxidize, agglomerate and produce peculiar smell when exposed to air and moisture.

· Dust removal: Full surrounding negative pressure dust collection cover at the filling port collects floating powder, keeps the workshop clean, reduces raw material waste and meets food hygiene requirements;

· Deaeration module: Squeeze out air wrapped in fluffy powder to prevent finished bags from bulging during storage and transportation;

· Nitrogen flushing system: Displace more than 99% internal air, residual oxygen in sealed bags ≤0.3%, effectively extend the shelf life of nutritional powder by 6–12 months.

4.3 Full Stainless Steel Hygienic Structure Compliant With GMP/HACCP

All parts in direct contact with powder (hopper, auger, filling nozzle, material chute) adopt food-grade 316L stainless steel, external frame is 304 stainless steel, all welding seams are polished without dead corners for residue accumulation. Quick disassembly design without tools: Auger, hopper and dust cover can be detached in 3 minutes for water washing, no residual protein powder oil stain breeding bacteria; fully enclosed acrylic safety baffle prevents powder splashing and operator safety accidents, meeting dairy food factory GMP production workshop standards.
