The standard is JB/T 6442-1992 "High Temperature Cleaning Machine", which stipulates the technical requirements of high temperature cleaning machine. The content covers the cleaning performance of the equipment (operation temperature range, cleaning pressure and flow), structural design (high temperature resistant materials, thermal insulation layer), control system (temperature precise control, automatic start and stop function), safety protection (overheating protection, leakage protection, anti-scalding measures) and corrosion resistance performance (inner wall anti-corrosion treatment), etc., and clarifies the performance indicators and test methods. It is suitable for equipment that uses high temperature liquid or steam for cleaning, and provides technical specifications for its design, manufacturing and quality control to ensure efficient degreasing and sterilizing cleaning in machinery, food and other industries, while ensuring the safety and reliability of equipment operation.
