METHOD AND AUTOMATED INSTRUMENT OF SOLUTION DENSITY MEASURING FOR CRYSTALLIZATION PROCESS CONTROL IN VACUUM-APPARATUS DURING SUGAR PRODUCTION

Abstract

In the work, based on the analysis of the methods of measuring the density of the solution to control the crystallization process in vacuum-apparatus during sugar production, it was determined that the existing methods are characterized by insufficient accuracy and automation of the technological process. A new method and automated means of measuring the density of the solution for controlling the crystallization process in vacuum apparatus during sugar production is proposed, which is characterized by high accuracy and the possibility of automating the technological process. An indirect method of measuring the density of the solution is proposed, which consists in measuring the height of the liquid column in two different ways: measuring the height of the liquid column by the manometric method and measuring the height of the liquid column by a capacitive sensor.
