Abstract: The present invention relates to an intelligent automated system for converting heterogeneous used cooking oil into biodiesel by dynamically identifying the physicochemical characteristics of individual feedstock batches and adapting the conversion process accordingly. The system comprises a feedstock receiving unit, a sensor-based characterization unit, a feedstock-fingerprinting and classification engine, an adaptive process-control unit, pretreatment and conditioning units, an esterification/transesterification reactor, automated reagent-dosing units, separation and purification units, and a biodiesel quality-monitoring unit. The characterization unit determines one or more feedstock parameters including free fatty acid content, acid value, moisture content, viscosity, density, temperature and other measurable characteristics. These parameters are combined with batch and operating information to generate a multidimensional feedstock fingerprint representing the condition and conversion suitability of the used cooking oil. The classification engine categorizes the feedstock and determines an appropriate processing pathway. Based on the generated fingerprint, the adaptive process-control unit automatically modifies one or more operating parameters including pretreatment requirement, methanol-to-oil ratio, catalyst quantity, reaction temperature, mixing intensity, reaction duration and sequential processing stages. During and after conversion, measured process and product parameters are compared with target conditions to generate feedback for corrective adjustment. The system thereby reduces dependence on fixed processing recipes, improves adaptability to variable-quality used cooking oil, minimizes reagent wastage and supports consistent biodiesel production. The invention further provides automated separation, purification, quality assessment, process-data recording and recovery of biodiesel and glycerol, thereby providing an integrated intelligent platform for decentralized and scalable conversion of used cooking oil into biodiesel.
