Introduction. The purpose of this study is to conduct a comprehensive analysis of innovative devices based on shape memory alloys (SMA's) for use in food technology apparatuses. Materials and methods. Physical and mathematical processes modeling, principles of the theory of automatic control, the theory of fuzzy logic were used. Results and discussion. The complex analysis of devices based on materials with shape memory effect (SME), which can be applied to food industry apparatuses, is made. In particular, design and principle of operation of the thermal valves, characterized by simplicity of construction and reliability, were analyzed. Design and principle of operation of the critical temperature increase indicator for machine's casing and the nut-indicator for overheating of sectional casing of technological machine, which increase the reliability of apparatuses were analized. Design and principle of operation of the thermal drives which can be effectively used in factories that need to utilize low-temperature thermal energy were analized. Design and principle of operation of the heliodrive were analized. Design of the critical temperature increase indicator for machine's casing is highly technological and reliable. Many factories need to utilize heat energy at relatively low temperature difference. These requirements are met by the design of the thermal drive. Power elements based on SME alloys have significant advantages: less mass, they can work in a wide temperature range, they have small dimensions, smooth movement of working parts, lower cost, high sensitivity. Drives based on heat-sensitive elements with SME are effective in solar power installations. [ABSTRACT FROM AUTHOR] |
