Three products were extruded in a co-rotating twin screw extruder F.lli Maris TM 30 MW (30 m diameter, ratio 40 L/D). The production process consisted of a pre-mix of all components of the formula and the following extrusion of the mix by dosing it in the main feeding.

Practical Fundamentals of Chemical Engineering

In commercial scale continuous operations the function of the workers and the supervising chemical engineer is to maintain the plant in proper running conditions. Maintaining required temperature, pressure, flow-rates, and other conditions is a very difficult task. Quality instrumentation is a must for maintaining these conditions.
