Control system for fresh pasta thermal treatment line
It's a control system for a thermal treatment plant producing over 100 kinds of fresh stuffed pasta (for example the "tortellini" pasta).
For each kind of pasta there is a different combination of parameters (receipts).
​
​
The system controls completely the thermal treatment plant, that 's divided in the following units (from input to output):
-
Elevator belt, that carries the product from the assembly line to the pastorizer, located in the higher side of the machine
-
Vibrant feeder, that distributes evenly the no-boxed product on the process belts
-
Pastorizer, a room where the suitable temperature to the thermic treatment is reached through a steam circuit. Here the product received more steam in order to avoid dryness
-
Vibrant dripping, the necessary step to dry the no-boxed product after the thermal treatment
-
Drying-room, a room with controlled temperature and humidity, where the product is dried
-
Cooling-chamber, a room with controlled temperature, where the product is cooled
​
Moreover, the control system co-ordinates the whole production line and consequently it communicates with following systems:
-
Steam production system for the thermal treatment
-
Refrigerating system
-
Machines used before the thermal treatment
-
Machines used after the thermal treatment
This system allows a completely automatic control of the line, mainly for the following operations:
-
System starting
-
System stopping
-
Maintenance of the functioning conditions
-
Management of alarms that don't require system stopping
-
Management of alarms that require system stopping
-
Emergency system stopping
-
Washing and drying (system maintenance)
