The maintenance and upkeep of the ultra-high temperature instantaneous sterilization machine should be combined with daily operation, regular cleaning, component inspection, and standardized management. The specific methods are as follows:
1、 Daily operation and basic maintenance
1. Check before startup
Check whether the sealing gasket, O-ring and other sealing components are intact to avoid damage and leakage.
Verify the functionality of pressure gauges, temperature gauges, and safety valves to ensure accurate sterilization parameters.
Confirm that the pipeline connections are secure and that the steam or cooling water pipelines are not loose.
2. Operating standards
Strictly set the sterilization temperature (usually ≥ 160 ℃) and time (15-30 seconds), and prohibit overloading operation.
The loading capacity of materials should be moderate to avoid excessive accumulation that affects the circulation of steam or heat medium.
2、 Cleaning and disinfection
1. Internal cleaning of equipment
Clean the sterilization chamber, heat exchange coil, and cooling sleeve after each use, remove residual materials to prevent scaling.
Use neutral cleaning agents to wipe the inner walls of the equipment (strong acid/alkali solvents are prohibited) to protect the stainless steel surface.
2. Pipeline system maintenance
Regularly disassemble the steam trap to clean impurities in the condensed water and prevent blockages from affecting steam flow.
Clean or replace the air filter monthly to avoid particle damage to pneumatic components.
3. Chemical Cleaning (CIP)
After running continuously for 6-8 hours, the cleaning procedure needs to be executed: rinse with clean water → alkaline solution (2% NaOH, circulate at 80 ℃ for 30 minutes) → secondary water washing → acid washing (neutralize residual alkaline solution) → final water washing.
3、 Key component maintenance
1. Replacement of vulnerable parts
Check the sealing ring, screen mesh and other components every six months, and replace them immediately if cracks or deformations are found.
Electric heating models require regular disassembly and cleaning of the electric heating tube to remove residual scale from the heat transfer medium (such as heat transfer oil).
2. Lubrication management
Add high-temperature lubricating grease to mechanical components such as bearings and chains every quarter to reduce wear.
3. Security system verification
The pressure gauge is sent to a professional organization for testing every six months, and the safety valve is calibrated once a year and a report is kept.
The temperature sensor is calibrated annually to ensure temperature control accuracy (± 1 ℃).
4、 Long term suspension management
1. Pre shutdown processing
Drain residual steam, cooling water, and materials from the equipment to prevent internal corrosion.
Apply rust proof oil to key metal components (such as cylinder piston rods) for protection.
2. Storage requirements
The equipment should be placed in a dry and ventilated environment, covered with a dust cover to prevent dust from entering the pipeline.
Regularly power on and maintain the control system to prevent the circuit board from becoming damp and malfunctioning.
5、 Fault prevention and emergency response
1. Exception handling: In case of steam leakage, abnormal temperature or abnormal response, immediately shut down the machine and cut off the power, and contact professional maintenance.
2. Safety protection: Wear protective equipment (gloves, goggles) during operation to avoid high temperature burns.
Attention: The specific maintenance cycle should refer to the equipment manual, as there may be differences in the component structure of different models (steam type/electric heating type).
