And ran a pilot for a 20 g protein, low-sugar drink with prebiotic fiber this morning, and our 3 mm aseptic filler nozzle decided 5°C is the perfect temperature to impersonate a cork. Anyone else balancing the more-protein-less-sugar drumbeat with a shear-thinning mix that turns into cold concrete at 6 a.m. line start, or is it just my pump auditioning for cement duty?

At 5°C that 3 mm aseptic tip absolutely “impersonates a cork” — we pre-warm the filler bowl/short loop to about 12°C and recirc 5–8 min, then drop back to 5°C once the matrix is sheared. If you’ve gotta stay cold, start with a 4 mm nozzle for the first 200 L and swap down — ever try that — https://dairyprocessinghandbook.tetrapak.com.
Backing @isabella_lee99, but instead of more heat, try a 30–60 s high‑shear recirc on a VFD bypass through the filler head to knock down the startup yield — just watch aeration before it turns into a bubble latte. Do you have an inline viscosity/torque trace to spot when it relaxes?
