Trima Automatic Bun Divider Rounder: K2/PRIMA DUO 2 lines

Compact Automatic Production

The Trima automatic bun divider rounder: K2 / PRIMA DUO is a fully automated machine designed to produce cut and rounded dough of handmade quality. Ideal for small production lines or artisans with a compact space looking to produce buns, rolls, or mini baguettes.

Capable of handling anything from bread rolls to soft donut-type dough to stiff pretzel dough, this machine will take up to 15kg (33lb) of dough in a funnel hopper and automatically cut and divide the dough into precisely weighed pieces, gently round each piece; and then drop them onto a conveyor. One person can operate this machine and produce up to 3,200 pieces per hour, eliminating a labour-intensive process. High production for the amount of floor space it occupies.

Stainless steel manufacturing and thoughtful design enable simple and hygienic cleaning. The rounding plate is coated with a Teflon material to handle even sticky dough. It is equipped with wheels.

Can be equipped with a touchscreen panel to set the weight of the divided dough pieces, rounding height, rounding speed, and rounding time, which you can store as recipes.

Trima also produces a larger version of this machine Trima Automatic Bun Divider Rounder KE/PRIMA EVO, with a row of 3, 4, 5, 6, or 8 conveyor lines (4000 – 9000+ pieces per hour), which can create additional production line possibilities.
