DRY CONTROL

Greater accuracy, greater stability, more control

 The development of Adaptive FLC (AFLC) permitting the use of 3 or more control exit signals instead of only one which in turn also gives greater control of the three controlling variables (rotation speed of the drum, feed of raw materials to be dried and drying temperature –fuel flow-) derived from a greater number of separate input signals (humidity and protein readings, rotation speed, feed of raw materials, drying temperature...).

The development of a mathematical model capable of integrating all the described inputs to be processed along with a data base and a rule base, to provide the resulting control parameters of the established outputs which will in turn give the desired set values for the final product with respect to its protein and humidity content.

The implementation of these two developments in a single control system corresponds to an innovation without precedent in the field of forage dying and Agrofood in general, where these systems have no similar prior developments and have been limited to individual studies which have not permitted the industrial development for the control and automation of the equipment with such precision. 

The development will allow a final system to be obtained with the following advantages: 

▪          Far greater accuracy to obtain a final product with a previously fixed humidity and protein content.

▪          Greater stability of the process, with none of the great oscillations in variables experienced with other systems using so many input and output variables. 

More reactive speed of control, responding in real time to whatever variation is observed in

the entry variables.

▪          Low cost of control, given that once the system is developed, given that once the system has been developed, that the software tools have moderate prices and the cont4rol mechanisms will not require specific developments.

▪          Real time control of the three process parameters: velocity of raw material feed, drying temperature and drum rotation speed.
