The article analyzes the sanitary treatment systems using the methodology of functional and cost analysis. The purpose of the work is to substantiate the most rational direction of improving the system of sanitary treatment of a milking machine. To achieve this goal, a functional model of this system was developed, an analysis of the significance of the functions performed and an analysis of the cost in the context of the significance of the functions was carried out. As a result of the functional and cost analysis, it was revealed that the most rational direction of improvement is the software part of the milking unit – it is a change in the content of cycles and their duration.
The article describes the improved design of a mechanical cleaner that improves the efficiency of the sanitization of a milking unit. The developed devices allow adding to the hydraulic effect of the washing solution the mechanical effect of the foam and bristle cleaning base. A description is given of the design and principle of operation of mechanical cleaners designed and manufactured at the Nizhny Novgorod State Engineering and Economic University with foam and scrubbed cleaning the base. The results show that if spiral holes are added to the structure, the rotation frequency of the structure increases by an average of 30%, and its linear speed decreases by 20%, compared with the previous design. The use of these devices can reduce the emission of detergents and disinfectants and thereby increase the environmental friendliness of milk production.
The article analyzes the technological schemes of sanitation systems, analyzes the technological solutions to improve existing systems. The aim of the work is to develop an effective structural and technological scheme of the sanitary treatment system of the milking unit.
When drawing up the structural diagrams of technological lines, an analysis of existing technologies was used. To determine the rational working scheme of sanitation, a systematic approach is needed with a thorough analysis of existing structures, parameters that determine the effectiveness of its functioning. Structural diagrams are a chain of successively arranged operations.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
