Automatic, continuous extruders are used for long pasta production, equipped with head for linear dies coupled with the automatic spreading machine.
After spreading onto the sticks the pasta is trimmed in length and the scraps are transferred automatically to the extruder mixer by means of a pneumatic system. Then, one operator shall have to put the sticks onto the trolleys and push them into the dryers.
The dryers are equipped with specific ventilation system and humidity exhaust system for long pasta enabling initial pre-drying phase (thus eliminating any extra costs for a pre-drying tunnel) which is automatically set in the PLC to the electric control panel. After drying one operator will take the trolleys out of the dryers, put the sticks onto the stick-removing machine, which automatically removes the long pasta, cutting it at the desired length for transport to the packaging machine.
