Q 1  : What are some differences and advantages of "Spiral Mixers without Bar" systems? 

-With this system user will have homogeneous and low friction mixing action due to wide diameter spiral and peripheral dough circulation around the bowl

-The central plinth acts as an additional "kneading surface" and its impact over the dough is certainly less "violent"

-The central plinth feeds the dough back to the spiral ensuring a fast development of the dough

-Usage of yeast will be less --> more water usage

-At the end of mixing , user will have well improved and uniform dough
