Abstract

The article presents the functionality of the incoming control system (ICS) of raw materials (frozen blocks) processed on an automated line for production of meat products. The parameters of the cutting process of raw materials depending on its temperature and the effectiveness of procedures for recognizing foreign inclusions in the raw materials have been studied. It has been determined that the key controlled thermodynamic parameters for a frozen block are not only the temperature of the meat layer directly in the grinding zone, but also the temperature of the subsequent layers (a mathematical model of the temperature front propagation) that determine the change in the plastic properties of the grinded meat. The authors performed a mathematical calculation of heat transfer in a block of frozen meat in the process of its grinding and an approximate method for calculating the assessment of the heat of phase transition is offered. A cost-effective option was found (based on a neural network-classifier that considers the cost function) for detecting foreign inclusions in raw materials (when creating an ICS), which makes it possible to determine the block size that can be triggered without the risk of entering the specified inclusion into the grinding product.

Highlights

In the domestic practice of producing meat products from frozen block meat, as a rule, continuous control of blocks using manual labor with preliminary defrosting of raw materials is used
The object is understood as meat chips in the form of a plate when it is separated from the frozen block of meat during the grinding process
Introduction of the temperature front as a mathematical model of heat transfer assumes the final rate of heat propagation in the body, in particular, in the meat product

Summary

Introduction

In the domestic practice of producing meat products from frozen block meat, as a rule, continuous control of blocks using manual labor with preliminary defrosting of raw materials is used This does not allow to fully automate the process of the production of meat products during their in-line production. Use of foreign equipment for incoming control of raw materials at medium and small meat processing enterprises is limited due to its high cost. These factors determine the relevance of development of domestic-made technical means for automated control of frozen meat raw materials, including those with expanded functionality in the case of its application on continuous processing lines using one-stage grinding of frozen meat. The incoming control system (ICS) of raw materials processed on an automated line is a subsystem of the IMS, which includes predicting the characteristic size of the resulting meat chips based on a mathematical model of the raw material cutting process with a multi-blade tool [1], and controlling the mixing of grinded meat with ingredients in a minced meat mixer for production of grinded meat with optimal functional and technological characteristics
