MATHEMATICAL MODELING OF THERMAL PROCESSES OF A DOUBLE-STONE PRESS-EXTRUDER WITH INDUCTION HEATER
Journal Title: Енергетика і автоматика - Year 2018, Vol 0, Issue 3
Abstract
The mathematical model of thermal processes during rapeseed oil processing on a two-screw extruder with an inductor has been improved, which provides the temperature regime specified by technological conditions for processing with a uniform and differentiated distribution of the power supplied. Based on the results of the work, a graphical characteristic of the temperature distribution in the working zone of the press extruder and the target theoretical graphical dependence is obtained, and the efficient use of energy is provided. The thermophysical phenomena that occur during the rape seed pressing process represented as follows: the heat energy generated by the heating devices is spent on heating the press body (increasing its heat content), partially transferred to the material moving in the body of the press, conductive heat transfer and thermal convention is transferred to the environment; from the moving material, the heat is transferred to the surface of the screw and spent on its heating. As a result of mathematical modeling, the possibilities of increasing the efficiency of the press extruder through the use of differentiated heating modes of the case, the graphical characteristic of the temperature distribution in the working zone of the press and the target theoretical graphical dependence, which will ensure more efficient use of energy, have been identified. According to a preliminary study, an increase in the width of the press body zone with a temperature of 115 ºС leads to a 16% reduction in the extruder engine power consumption by changing the physical characteristics of the rape's oil material when the temperature rises.
