ISM 250

A 265 qt heavy spiral mixer built for continuous production shifts. Reversing bowl, breaker bar and a strong two-speed drive handle large bread and pizza batches cool, hour after hour.

Bowl capacity265 qt
Flour / cycle240 lb
Dough / cycle330 lb
  • 265 qt (250 L) AISI 304 stainless bowl: rated for 240 lb of flour per cycle at 60% hydration
  • Cool, low-temperature kneading: the spiral arm and breaker bar develop gluten fast without warming the dough
  • Reversing bowl on -32S: turns into the spiral and reverses to fold and incorporate large batches faster
  • Two-speed drive with dual timers: slow to combine, fast to develop, repeatable cycle after cycle
  • 7.5–10.0 HP motor on 208–240 V / 3-phase / 60 Hz, wheels and leveling feet
Key features

Features and construction

Heavy spiral kneading near the top of the range. The ISM 250's 265 qt (250 L) bowl turns out about 330 lb of dough per cycle, with the reversing -32S bowl standard for fast, even, low-temperature development.

Cool low-temperature kneading

A spiral works the dough against the breaker bar instead of dragging the whole mass, so friction heat stays low. The dough leaves the bowl cool, which protects the yeast, the fermentation schedule and the final crumb.

Reversing bowl + breaker bar

The motorized bowl turns into the spiral; on -32S models it reverses to fold and incorporate faster. A fixed breaker bar splits the dough on every rotation, so a full batch develops evenly edge to center.

7.5–10.0 HP two-speed drive

A strong pulley-belt drive with two speeds and dual timers: a slow speed to bring the mass together, a fast speed to develop it. Repeatable cycles shift after shift, with the torque to handle a full bowl of stiff dough.

AISI 304 stainless build

Food-grade AISI 304 on the bowl, spiral arm and breaker bar. The full AISI 304 stainless-steel body "CR" build is available as a standard option for washdown environments and easy cleaning at the end of continuous production shifts.

Built-in safety

A stainless safety cover with auto-stop halts the spiral the moment it is raised. IP54-rated controls and an IP32 machine rating suit demanding bakery floors, with wheels and leveling feet for easy placement.

Manufacturer-direct value

The ISM 250 is quoted straight from the factory that welds the frame. No importer, no regional rep, no distribution markup between us and your purchase order. That is the Dirmak model at every capacity.
