The research of one-stage particle size-reduction process of blocked frozen meat with multiple cutting tools with milling operation method

Abstract

This article shows experimental data about energy demands of innovative one-stage particle size-reduction process of frozen meat, formed in blocks, with milling operation method. We researched the particle size-reduction of meat blocks (beef and pork) by tools of different construction and shape of cutting edge: a slab mill with small edge and a fitted on shaving milling tool with a hard-faced knife. This study based on results of measuring three-phase active power, used by the cutting electric drive in working condition. The article presents the calculation of the measurements of numerical characteristics (mean value and mean square deviation) of statistical samples of power values with completing particle size-reduction tool with milling tools. The research shows that placing additional sustainer, that fixes a block of meat directly near the cutting zone, leads to decrease of energy demands for the cutting process up to 20% and to lower the dispersion of power values more than three times. The data obtained during the research let work out technical requirement specification for producing a commercial prototype of cutting particle size-reduction. The data allow creating the calculate method of numerical characteristics of a random process for a load of multiple razor tool in working condition. That model is used for designing an intellectual system of management of technological process on the transfer line for meat product producing with using one-stage particle size-reduction of raw materials with the milling method.
