Tweedy™ laboratory mixer
Pressure-vacuum lab mixer for bakery R&D
Pressure-vacuum laboratory mixer for pilot-scale bakery production
The Baker Perkins Tweedy™ 8 and Tweedy™ 20 mixers are pressure-vacuum mixers designed for lab production. Built to replicate the process conditions of full-scale pressure-vacuum industrial mixers, they allow new recipes and formulations to be developed using pressure-vacuum processes with confidence before scaling up.
Control the aeration and texture of your end products, including for:
- Bread and sandwich loaves
- Burger buns and sweet rolls
- Pizza and flatbreads (pita, focaccia, ciabatta)
- Artisan and hearth-style breads
- Bagels, brioche, and rye products
- Batter and breadcrumb applications

Accurate scale-up to production
The Tweedy™ system incorporates the same critical control parameters used in industrial mixers. Therefore, results achieved during testing can be reliably transferred to full production lines. This ensures consistency, reduces risk, and shortens time-to-market for new products.
Flexible and controlled mixing
In addition, variable speed control and pressure-vacuum functionality provide precise dough development. Even with smaller batch sizes, the mixer maintains consistent process performance. This flexibility makes it ideal for product trials, formulation adjustments, and process optimization.
Designed for R&D environments
The system is specifically engineered for test bakeries and laboratory settings. It enables easy monitoring, repeatable results, and efficient experimentation across multiple formulations.
