Primo PSM-50E Spiral Mixer

Primo PSM‑50E Spiral Dough Mixer – 25 kg Flour / 40 kg Dough, 2‑Speed Auto

Batch after batch of perfectly-developed dough—without the operator babysitting the bowl. That's the promise of the Primo PSM-50E Spiral Mixer. Designed for artisan bakeries, pizza kitchens, and commissaries, this rugged unit transforms up to 25 kg of flour or 40 kg of finished dough into silky-smooth, oxygen-rich mixes in minutes. A single high-torque motor delivers two precision gear-driven speeds (135 RPM / 270 RPM) and can run in manual, semi-automatic, or fully automatic mode—switching from first to second speed on its own, then shutting off when the timer hits zero. This intelligent sequencing eliminates guesswork and ensures consistent gluten development across every batch. Stainless steel construction on the bowl, spiral hook, safety guard, and kneading bar guarantees food-safe durability and withstands the demands of high-volume production. The reverse-spin feature—exclusive to the 50E and 60E models—lets you tap the reverse switch to spin the bowl backward for effortless dough removal, cutting cleanup time significantly. Front and rear casters make repositioning a one-person job, while the compact footprint fits tight kitchen layouts without sacrificing capacity. Backed by Primo's reputation for reliability and value, the PSM-50E is the smarter way to scale production without scaling labor costs. Mix larger. Mix faster. Mix Primo.
