Periodic inspection

Periodic inspection

Only taking the annual inspection with class-1 high-pressure vessels is not enough for maintaining the performance of sterilizers.
Daily inspections and periodic inspections must be carried out and maintenance needs to be carried out according to the conditions.
We recommend a "periodic inspection" in which a specialized service staff checks and adjusts important points and diagnoses equipment malfunctions.

Inspection details unique to equipment manufacturers

Conduct a trial run of the equipment after a periodic inspection.
Staffs who understand the operation of the various valves and the operation of each process are dispatched.
Advice on maintenance
Propose systematic maintenance while prioritizing
Measure the temperature in the tank with data trace (compact data logger).
Check that the sensor is not shifted (simple calibration).
* If the deviation is large, suggest calibration.

Risk of inspection and maintenance failure (in the case of retort sterilizer)

Unusual pressure
The product may be deformed or damaged.
Temperature error
If the temperature is low, the product may not be sterilized enough.
If the temperature is high, over-sterilization will occur.
Others
If an operation error occurs, the process stops halfway and production stops.
Hot water or steam above 100℃ may be emitted dangerously.
The risk of product disposal due to trouble increases.

Preventing troubles with preventive maintenance with periodic inspections eliminates sudden expenditures and consequently saves maintenance and management costs in total.
