MOBILE APPLICATION FOR CALCULATING THE COEFFICIENT OF EXPANSION OF BARLEY EXTRUDATE

Abstract

The article discusses the experience of creating a mobile application for calculating the coefficient of expansion of barley extrudate, depending on the adjustable parameters of extrusion processing (temperature at the exit from the die 120-150 ° C, moisture content of raw materials 20-24% and screw rotation speed 260-340 rpm ). Analysis of the world scientific literature indicates the prospects for processing plant raw materials using extrusion technologies. In production conditions, it is not always convenient to use a lot of experiments to fine-tune the technology and obtain the required coefficient of expansion of the extrudate for the target raw material. It is possible to obtain the required extrusion parameters depending on the adjustable parameters of extrusion processing based on mathematical relationships that were obtained on the basis of experimental data. The purpose of the work is to develop a mobile application for calculating the expansion coefficient of barley extrudate. Android Studio 4.2.1 was used as a development tool. The application was written in Java for Android API Levels 5.0 - 11.0. The developed mobile application based on a mathematical prediction model allows calculating the expansion coefficient of barley extrudate with a high degree of reliability. By entering the values of the temperature at the outlet of the die, the moisture content of the raw material and the speed of rotation of the screw, the calculated value of the coefficient of expansion of the barley extrudate is calculated.
