Spirulina Powder

Spirulina is an ultra-fine algae powder with intense pigment — it stains everything, and its nutrients degrade in light and oxygen. Those two facts set the terms for the line. The particles are very light, so any open transfer puts a green cloud into the room; it settles on frames, photocells and sealing jaws, where a trace of pigment marks the next pack and weakens the seal. Being non-free-flowing, spirulina does not pour on demand: it bridges over the hopper outlet, compacts under its own weight and changes apparent density as the hopper empties. Auger dosing is the method, for a specific reason. A volumetric cup measures volume, not weight; with a powder that compacts differently at every hopper level, volume and weight drift apart and fill weights wander. A servo auger meters by screw rotation, an agitator keeps breaking the bridge above it, and the powder travels inside a closed tube straight into the pack — no free fall, no cloud. That is what enclosed, dust-tight auger dosing buys: the deep green stays where it belongs. Stainless contact parts and tool-free strip-down matter more than usual, because pigment carried into a lighter blend shows on the first pack. Stick pack leads the category — daily-dose sticks for smoothies are the leading consumer format, and most brands build around them. A spirulina stick pack machine runs several lanes, and light-blocking high-barrier film counts as much as the dosing, because that is what protects potency. The three- or four-side-seal sachet covers samples, trial packs and the pharmacy channel, so a spirulina sachet packaging machine is often specified next to the stick line. For larger doses, foodservice and refill packs, VFFS pillow bags and doypacks cover the range, with nitrogen flush where oxygen inside the pack is the concern. Dose range and output are set per project, not read from a table. Fill weight, the bulk density of your blend after aeration, film width and lane count give the figures; on a multi-lane machine, packs per minute equal machine cycles multiplied by lane count, and lane count follows pack width — a narrower stick allows more lanes across the same web. Because spirulina density varies with supplier, drying route and blend, we set the auger and confirm output on a sample of your own powder. Mentpack builds the auger-dosing stick pack and sachet machines this product needs: dust-tight dosing groups, agitated hoppers and quick strip-down parts for cleaning. Lane count, dosing group size, film specification and nitrogen flush are configured around your pack and your powder, so a spirulina powder filling machine is proposed after we see a sample and the target pack. Typical customers are supplement and nutraceutical brands, superfood and greens-blend producers, sports nutrition companies, algae growers packing their own harvest, and contract packers running private label. The task is the same everywhere: keep the green inside the pack, light and oxygen outside.
