Intelligent data analysis in an automated system of input control of raw materials on a continuous process line for the production of meat products

The article considers conditions for partial grinding of a frozen meat block in case of detection of extraneous inclusion in it by the raw material input control system. The processing of raw materials occurs on an automated in-line production line for meat products using a single-stage chopping process. The authors stipulate a continuous inspection of all meat blocks with full automation of control operations. Localization of the layer of meat containing inclusion solves the trajectory problem of moving the block of raw materials in the guiding planes of the single-stage chopper with the establishment of a mandatory safe chopping zone. The analysis helps to determine the boundaries of the safety zone. When solving the trajectory problem, the authors accept the assumption of a rectilinear trajectory of movement of a block of meat during its single-stage chopping. The foundation of this presumption stems from a research study of the energy usage of the drive of the raw material cutting mechanism in the working mode. The calculation of estimates of numerical characteristics of the experimental distribution of power consumption of the electric motor drive of the cutting mechanism allows to judge about the reduction of dynamic loads in the technological system “shredder - meat block” causing deviations from the plane-parallel motion of the meat block, because of rigid fixation of the block in the cutting zone. Using the control system reduces the risks of using substandard raw materials within its competence while maintaining the productivity of the technological line

Abstract Currently, frozen meat blocks are widely used in meat processing for production of sausages and other meat products. Efficient grinding of frozen raw meat is an urgent task for meat industry professionals. The V.M.  Gorbatov All-Russian Meat Research Institute has developed energy- and resource-saving process for grinding of frozen meat blocks by milling. Determination of energy consumption for grinding of raw materials by multiple edge tools (milling tools) is the most important step in the creating of new type mincing machine.Аннотация В настоящее время замороженное блочное мясо широко используется в мясоперерабатывающем производстве для выработки колбасных изделий и другой мясной продукции.

Automated incoming control with advanced functionality for processing frozen meat raw materials on continuous process lines with application of single-stage grinding

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

Energy-saving technology for fine grinding of food raw materials frozen in blocks

Reducing the cost of electricity consumed when cutting frozen raw materials in the meat processing industry can significantly improve profitability and other economic indicators. The possibility of energy saving in the innovative technology of one-stage fine grinding of food raw materials was studied. The selected frozen meat blocks (beef and pork) and collagen-containing raw materials (meat cuttings and tripe) were ground to the required degree usingan experimental IBF-1 grinder. At the same time, the active three-phase power consumed by the electric motor of the cutting mechanism drive was measured and recorded. The study results showed that the IBF-1 grinder (milling method) could replace three machines (frozen meat cutter, meat comminutor, and micro cutter) with sequential grinding in three stages according to the standard grinding technology. The calculations carried out on the power costs per ton of products confirm that grinding requires 2.6 times less than the total installed capacity of meatcutting machines of the standard technological chain
