AI Technical Summary

Technical Problem

In low-temperature, high-viscosity environments, existing fruit juice extraction equipment struggles to achieve efficient cell-level cell disruption, resulting in low juice yield, easy failure of sterile sealing boundaries, and a lack of dynamic adaptive feedback control, leading to an unstable extraction process.

Method used

By employing a flexible gradual pressurization module, a micro-pressure pulse excitation module, and a flexible antagonistic compensation module, combined with an extraction control module to adjust parameters in real time, static pressure holding stress and microscopic cavitation effect are achieved, and dynamic adaptive feedback control is used to control the cell wall breaking process of fruit pulp fibers.

Benefits of technology

Highly efficient cell wall disruption is achieved under low-temperature conditions, increasing juice yield, avoiding temperature rise and pectin dissolution, ensuring aseptic sealing stability, and improving the stability of the discharge flow rate.

Abstract

The present application relates to the field of food processing machinery and deep processing equipment of fruits and vegetables, in particular to a fruit juice extraction equipment based on a sterile cold filling system; the equipment comprises a main extraction cabin, flexible gradual pressure increasing, micro-pressure pulse excitation, flexible antagonistic compensation and extraction control module; the system records the frequency spectrum of the slight fluctuation of air pressure and the harmonic distortion rate of current, and reversely calculates the viscosity change and macroscopic wall breaking rate of the solid-liquid two-phase flow in the cabin; the core of the present application is to calculate the equivalent stiffness of the fruit pulp based on the impedance viscosity wall breaking stiffness compensation model, and to dynamically adjust the excitation frequency and the inflation pulse width; the present application abandons the direct cutting and high-pressure extrusion of traditional rigid components, and realizes cell-level wall breaking by using the micro-cavitation effect induced by flexible pressure increasing and non-contact pulse excitation, solves the problems of excessive local temperature rise and excessive pectin dissolution, effectively improves the juice yield, and significantly reduces the risk of failure of the sterile sealing boundary.
