Built on Decades of Mixing Expertise
Pentagon Bakery Systems was founded in 1991 by Ron, an engineer whose career in mixing technology spans over three decades. Ron's journey began at Carters Electrical, where he cut his teeth on domestic appliance repair and industrial installations, before moving to Tweedy's — the company that pioneered high-speed dough mixing in the UK. Over ten years at Tweedy's, Ron developed an unrivalled understanding of pressure-vacuum mixing technology and the science behind consistent, high-quality dough production.
After Tweedy's, Ron spent eight years at Baketec, a Lancashire-based company supplying laboratory mixers to bakeries across the UK, Europe, Saudi Arabia and the USA. It was during this time that the ambition to build something of his own took shape.
The catalyst came when Fletchers of Sheffield approached Ron to build a T35 mixer incorporating pressure-vacuum technology, working alongside the British Oxygen Company (BOC) who supplied the gas systems critical to the pressure-vacuum process. This project proved that Ron could design and build complete mixing systems independently, and Pentagon Bakery Systems was born.
Ron's vision was clear from the start: build a laboratory mixer compact enough to fit under a bench, but engineered to replicate every critical process control found on full-scale production systems. Where the original Tweedy had a single mixing stage with basic timer, energy meter and vacuum controls, Ron engineered the K5 with four fully programmable stages, full PLC control and recipe storage — allowing operators to run multiple recipes with different speeds, pressures and mixing sequences.
Over the years, Pentagon has continued to refine and expand the range, adding options for variable speed control, adjustable pressures and aeration capabilities. But the core engineering principles that Ron established remain unchanged. The K5 and K16 mixers — with batch capacities of 5kg and 16kg — are now trusted by test bakeries and R&D laboratories worldwide.
When Ron made the decision to retire, multiple parties expressed interest in acquiring the business. Singleton Engineering stood out as the clear choice — they had the strongest vision for how to take Pentagon forward and the enthusiasm to invest in the next chapter.
