This invention relates to the field of food processing equipment technology, and discloses an adaptive control system for aroma preservation, dehydration, and drying parameters of a strong-aroma oil press. The system includes a processing and execution unit, a multi-dimensional sensing unit, and a central control and calculation unit. Based on data from the multi-dimensional sensing unit, the central control and calculation unit calculates the average adsorption saturation of the cake (used as an adsorbent) in real time and compares it with a preset threshold. It then executes two branch control strategies: when the saturation is high, the system determines that the adsorbent efficiency has decreased and decides to perform a new cake addition operation to restore dehydration momentum; when the saturation is in the high-efficiency range, the system calculates and adjusts the optimal stirring speed by solving a multi-objective optimization problem targeting dehydration rate, aroma emission intensity, and stirring power. This invention can significantly improve dehydration efficiency while effectively preserving the product aroma, and improve the automation level of the dehydration process and the consistency of product quality.
