Modeling and optimization of olive stone drying process

Olive oil can be extracted from dried olive stones. Drying of olive stones is a procedure difficult to model. The equations describe heat transfer inside the drying cylinder are highly non linear and therefore the mathematical models used to simulate the drying process are complicated. Here we suggest fuzzy and neurofuzzy techniques to control the drying procedure. A fuzzy controller is designed based on available expertise, while a neuro-fuzzy controller is built using the Adaptive Neuro Fuzzy Inference System (ANFIS) based on experimental data. Both controllers tested in various operation conditions and extensive comparative results are presented.
