Abstract
This article examines the role and importance of the spring element in a screw press to optimize the juice extraction process. The spring is an elastic component capable of storing and redistributing mechanical energy while maintaining consistent pressure. The study provides a detailed analysis of the geometric and force parameters of the spring (outer diameter, wire diameter, stiffness, working deformation, and stress). Based on standard formulas and GOST regulations, optimal spring characteristics were identified to ensure strength, dynamic stability (𝜐𝑚𝑎𝑥/𝜐𝑘 ratio), and operational reliability. Proper selection of the spring’s structural features ensures even pressure distribution during pressing, enhancing juice yield and promoting complete raw material processing. Compliance with durability class and load conditions guarantees long-term and reliable operation of the equipment. The results contribute to the improvement of technological units and automation of processes in the domestic food industry. Moreover, this approach enables resource savings and enhances energy efficiency, which is a critical factor in modern production environments.
