The increasing demand for functional foods those enriched with bioactive compounds to provide health benefits beyond basic nutrition necessitates innovative approaches to their production, particularly in the precision control of nutrient delivery. This paper presents the development of advanced mechanical devices designed to enhance the accuracy and efficiency of nutrient delivery systems in the manufacturing of functional foods. These devices are engineered to regulate the infusion of essential nutrients, such as vitamins, minerals, and bioactive compounds, into food matrices with high precision, ensuring uniform distribution and consistent product quality. The proposed systems utilize state-of-the-art technologies, including microfluidics, piezoelectric actuators, and smart sensors, to achieve precise control over the flow rates and concentrations of nutrient infusions. By integrating these devices into existing food processing lines, manufacturers can achieve higher accuracy in nutrient delivery, reduce waste, and improve the overall nutritional profile of their products. Additionally, the smart sensors incorporated within the devices provide real-time feedback, enabling dynamic adjustments to maintain optimal conditions throughout the production process. The research also explores the potential of these mechanical devices in various functional food applications, such as fortification of dairy products, beverages, and bakery goods. Experimental results demonstrate significant improvements in nutrient retention and bioavailability, as well as enhanced sensory properties of the final products. This innovative approach not only meets the growing consumer demand for healthier food options but also aligns with industry trends towards automation and sustainability. The development and implementation of these precision control devices represent a significant advancement in the field of functional food production, offering a scalable solution for enhanced nutritional value and product consistency.
