The VCM’s have been around for a very long time, and with the correct mixing attachment (flat and dull for dough and curved and sharp for cutting veggies or cheese) they will serve you well. As indicated, the average mixing time with these mixers in in the 70 to 90-second range. If you need to mix multiple doughs back to back, temperature build up in the bowl can be a problem, but this is easily addressed by pouring a couple gallons of ice water into the bowl to cool it between doughs. The more common version of a VCM is the Robot Coupe Mixers. I was at a large pizza commissary in Latin America some time back, and they were using their VCM’s to mix everything from dough to sauce (made from fresh, whole tomatoes) to cutting the cheese that was sent out to the stores. As for the quality of the dough made on a VCM, it’s as good as any other dough, but be aware, it is very possible to over mix a dough using the VCM, seconds count! Also, due to the very short mixing time, fresh yeast should be suspended in the water, and IDY should be pre-hydrated like ADY, except in 95F water, before adding it to the bowl.
