Fatty acid value analyzer is a specialized testing equipment for measuring the fatty acid value of grains such as rice, brown rice, rice, and aged grains. This article will provide a detailed introduction to its operation steps and maintenance methods to ensure the normal operation of the equipment and the accuracy of the measurement results.
1、 Operation Guide
Instrument preparation
Ensure that the instrument is placed on a level and stable workbench and connected to a power source.
Check if the pump flow rate, mixer, and other adjustable parameters are in their initial state.
Sample preparation
Take an appropriate amount of grain samples and preprocess them according to relevant national standards such as GB/T20569, GB/T20570, or GB/T5510.
Measurement steps
1. Power on preparation: Turn on the fatty acid value tester and wait for the experiment.
2. Set parameters:
Pump flow rate: Adjust to 0.5ml/min-10ml/min according to experimental requirements.
Mixing speed: Adjust to 10-250r/min to ensure thorough mixing of the sample.
3. Start measurement:
Start the measurement program according to the instrument operation manual.
Monitor the titration process and record the measured values.
4. Record data: Record the measurement results to ensure that the double experimental difference meets the national standard requirements (such as the double experimental difference of rice fatty acid value ≤ 2mg/100g).
Shutdown and cleaning
After the measurement is completed, turn off the instrument power.
Take out the sample, clean the sample tank and other parts that come into contact with the sample to ensure there are no residues.
2、 Instrument Maintenance Guide
routine maintenance
After each measurement, clean the sample tank and pump pipeline to prevent sample residue from affecting the next measurement.
Regularly check the pump flow rate and the working status of the mixer to ensure that the parameters are within the normal range.
periodic calibration
Regularly calibrate the instrument according to the calibration guidelines provided by the manufacturer to ensure the accuracy of the measurement.
During calibration, use standard samples for comparison and adjust instrument parameters.
troubleshooting
If there is any abnormality in the instrument, such as unstable pump flow or malfunctioning agitator, professional technicians should be contacted in a timely manner for maintenance.
Regularly check the power cord and interface to ensure that the connection is secure and not loose.
Storage conditions
The instrument should be stored in a dry and dust-free environment, avoiding direct sunlight and high temperature and humidity.
When not in use for a long time, the power should be disconnected and covered with a dust cover.
Precautions for use
Strictly follow the operation manual during operation to avoid overloading.
Avoid placing strong magnetic fields or vibration sources around the instrument to affect the measurement results.
summary
Fatty acid value analyzer is an important equipment for measuring the fatty acid value of grains. By following the correct operating procedures and regular maintenance, the stable operation of the instrument and the accuracy of the measurement results can be ensured, thereby better meeting the needs of food quality control and safety testing.
