Multi-criterion selection of wolf mixers

Abstract

The quality of the finished sausage product is affected not only by the quality of raw materials, but also by the process of grinding the meat and obtaining high-quality minced meat. Planning production lines in the food industry is associated with difficulties due to the need for an informed choice of the right equipment. Therefore, the purpose of this work is to increase the technological efficiency of meat processing by determining the rational type of mixer-mixer by the method of multi-criteria analysis of the equipment. On the market, stirrers are available in different capacities with different diameters of the grids of the stirrers and the capacity of the working chambers of the stirrers. For the initial evaluation of the technical perfection of the equipment according to its energy intensity, the criterion of throughput energy intensity and the energy intensity of the mixing process were selected. To find effective options, the principle of dominance according to the Pareto method was applied. For the final evaluation of the machines in the multi-criteria analysis, the method of the distance to the target according to the coefficients of energy and metal capacity was used. The obtained values of the throughput energy capacity of the analyzed agitators vary from 0,098 to 0,415 kW/mm, while the energy capacity of the mixing process varies from 0,00314 to 0,01375 kW/l. The value of the energy density coefficient varies from 0,0031 to 0,011 (kWh)/kg, while the metal density coefficient varies from 0,127 to 0,675 (kg·h)/kg. The obtained data can be used in the design calculations of similar equipment. Combo Grind 1500/250 by GEA turned out to be the closest to the ideal version. This machine has a special design, which distinguishes it from other "classical" schemes of execution of mixers.
