In our last blog, we took you behind the scenes of oral liquid supplement manufacturing—from formulation and mixing to nitrogen-flushed filling and final inspection. Before that, we explored the step-by-step process of powder supplement manufacturing—from raw-material sourcing to blending and packaging. If you missed either tour, catch up here:

Now, let’s dive into how whey protein—one of the most popular powder formats—is expertly produced.
Overview of Whey Protein Manufacturing
Whey protein starts as a liquid by-product of cheese making. In a GMP-certified factory like Sinofn Health’s, that liquid undergoes drying, transport, and packaging steps to become a stable, high-protein powder your customers trust.
Step-by-Step Whey Protein Production Process
1. Powder Dense-Phase Transportation
Once spray-dried or atomized, whey protein concentrate or isolate is moved via dense-phase pneumatic conveyors. This low-impact method preserves particle integrity and prevents segregation.
2. Automatic Weighing & Filling
Each batch is precisely weighed by automated dosing systems. The powder is then filled into cans or pouches to within ±1 g accuracy, ensuring consistent scoop sizes.
3. Vacuuming Process
Before sealing, containers enter a vacuum chamber to remove air and moisture. This step extends shelf life by preventing oxidation and microbial growth.
4. Nitrogen Filling & Sealing
Following vacuuming, cans are flushed with food-grade nitrogen and hermetically sealed. The nitrogen blanket protects sensitive amino acids and preserves freshness.
5. Package Cleaning
Sealed containers pass under automated blow-off nozzles and brushes to remove residual powder—guaranteeing a pristine outer surface for labeling.
6. Laser Coding
A laser marking system etches batch numbers, manufacturing dates, and expiration dates directly onto the can. Laser coding is tamper-proof and smudge-resistant.
7. Automatic Capping
For jars with screw or snap-on lids, robotic capping heads apply uniform torque to each container—eliminating cross-threading and ensuring airtight seals.
8. Packaging & Warehouse Dispatch
Filled, sealed, and coded cans are collated into cartons, palletized, and moved via automated guided vehicles into climate-controlled storage. They’re now ready for global distribution.
