The objective of the study is to analyze the development dynamics of instrumentation for intensifying membrane concentration (separation) processes for liquid process solutions based on inventive practice in the food and processing industries, as well as to identify the basic structural components and technical results characterizing them. The object of the study is the instrumentation for membrane separation and concentration of liquid heterogeneous systems in the food and processing industries of the agro-industrial complex. The research methods include a systems analysis of the development dynamics of design solutions and a review of the problem field, as well as a statistical method for quantifying the intensity of inventive activity to improve membrane apparatuses for concentrating and separating liquid media. Primary attention is paid to a comparative analysis of designs and their advantages and disadvantages, such as material consumption, operational complexity, hydraulic resistance, etc. The conducted analysis of literary and patent data revealed four main classes of devices for baromembrane concentration (separation) of solutions with the intensification of the process by applying a constant current density: electric baromembrane devices of the flat-frame (flat-chamber) type (EBMAPT), EBMATT (tubular type), EBMART (roll type), EBMAKT (combined type). The analysis of the research results showed: 1) EBMAPT provide the productivity acceptable for production, but their use requires significant material costs; 2) EBMATT are compact and efficient, but difficult to operate; 3) EBMART have a high filtration area and productivity, but their repair is difficult; 4) EBMAKT combine the advantages of flat-chamber and tubular type devices, but the length of their separation channel is large, which affects the hydraulic resistance. Based on an analysis of the hardware design of various types of membrane devices for intensifying membrane concentration (separation) of liquid food systems, a classification scheme based on design is proposed.
