In this work, several configurations of Artificial Neural Networks (ANN's) for the Feedforward type are simulated in the specification of an ANN model to predict the formation of Acetaldehyde from the evaluation of the parameters of the PET packaging preform manufacturing process, generating information to support decision-making on optimal silo temperature control in PET resin drying, enabling specialists to make the necessary regulation decisions to lower ACH levels. The materials and methods were applied according to the manufacturer's characteristics on the moisture in the grain of the PET resin, which may contain between 50 ppm and 100 ppm of ACH, and for the analysis of the methods, data were collected, according to the temperatures and times of residence used in the blow injection process in the manufacture of the bottle preform, the generation of ACH from the PET bottle after the solid post-condensation step reached residual ACH levels lower than (3-4) ppm, as per the desired specification, reaching levels below 1 ppm. The results were found through simulations of Computational Intelligence (CI) techniques applied by ANNs, where they enabled the prediction of ACH levels generated in the plastic injection process of the preform of bottle packaging, allowing an effective management of the production parameters, helping in strategic decision making regarding the use of temperature control during the drying process of PET resin.pdf.Temperatura de SecagemRedes Neurais ArtificiaisInteligência ComputacionalPETAcetaldeídoDissertação1.03.00.00-7 Ciência da Computação
