Extrusion Taffy Machines. The name pretty much says it all here – these machines work using the extrusion principle, where an extruder helps you to shape and cut the taffy as you see fit. Batch Cookers. The main feature of a batch cooker is its ability to cook a taffy mixture before it is allowed to pass through the shaping and pulling stages.
