A control system of a citrus fruit juice production line

Abstract

This invention discloses a control system for a Wogan mandarin orange juice production line, specifically relating to the field of juice processing technology. The system includes a dynamic ingredient dispensing module, a collaborative processing module, and a feedforward stabilization module. The dynamic ingredient dispensing module monitors the content of pectin, cellulose, free peel oil, and turbidity online. It accurately calculates the addition amounts of three stabilizers—pectin, xanthan gum, and konjac gum—using a nonlinear multi-objective optimization model, and establishes a closed loop for post-addition re-inspection and secondary replenishment. The collaborative processing module employs ultra-high pressure homogenization to refine the pulp particles, combined with electromagnetic field collaborative processing to deactivate pectin methyl esterase activity and promote peel oil microemulsification. It dynamically adjusts process parameters by monitoring particle size and zeta potential in real time. The feedforward stabilization module constructs a feedforward model based on historical data and uses a PID algorithm to fine-tune parameters based on accelerated storage feedback. This invention achieves dual collaborative control of pulp sedimentation and peel oil flotation, improving product stability and the level of production line intelligence.
