Numerous exhibitors will present their innovations in Munich. The editors submit a couple of novelties to give trade fair visitors an insight.

Come and experience the next generation make-up line from Stewart Systems. The new High Speed Bun Make-Up line offers a variety of improvements. The most notable development is the detachable manifold assembly which can roll away and allow for easier cleaning. It is removed from the main divider body without needing tools. The manifold itself can also be cleaned by removing the inspection cover, also without needing tools. The main divider body essentially serves as a dough pump and can attach to a manifold assembly of the customer’s choice.

The exterior of the dough divider is now a hygienic wash-down design and the overhead proofer is easier to clean. Overhead side panels are removable with one simple tool for safety. Single swing-away bottom panels make it easier to dispose of accumulated flour dust. The molder is also updated with a redesigned indexer fitted with encapsulated magnets. Cleaning and part replacement are now easier than ever.

This year at the iba, Spooner Vicars will showcase the Vortex high speed, horizontal mixer for cookie, biscuit, cracker and other similar hard and soft doughs. Spooner Vicars’ unique sprag, a fixed stator inside the bowl, allows the dough to be folded, sheared and kneaded thoroughly. Research has shown this to reduce mix times significantly compared to other bowl/blade designs. Temperature is important and the sprag houses a temperature sensor to monitor this, while the bowl is jacketed to permit water circulation from an external source to maintain the ideal bowl temperature.

Capacities range from 350 kg to 2,400 kg and in the case of tough cracker doughs robustness is vital, and so is motor power and duty. The 750 kg mixer, for example, uses a 90 kW heavy duty Variable Frequency Drive with programmable speed and slow start ramps to handle torque when switching from low to high speed cycles.

On board software allows mixing to time, temperature or energy so that the baker can build a valuable history of mix parameters to accommodate flour variations and differing ambient conditions.
