The wheat appearance quality analyzer is an important tool in the fields of grain and oil quality inspection, storage, and processing. It achieves rapid detection of imperfect wheat grains through image analysis and artificial intelligence technology. Proper use of equipment and adherence to operating procedures can ensure the accuracy of test results and extend the lifespan of the instrument. The following will explain from two aspects: usage methods and precautions.

Usage: Three steps to complete efficient detection

1. Preliminary preparation and equipment startup

Environmental RequirementsPlace the equipment in a dry laboratory or quality control room without direct sunlight to avoid dust and vibration interference. Before starting up, check the stability of the power supply to ensure that the voltage meets the equipment requirements (usually220V±10%）.

System self-test: After the power is turned on, the device automatically performs system initialization, including camera calibration, light source stability testing, and moreAIModel loading. This process requires approximately2During the minute, the device needs to be kept stationary.

Parameter setting: Through10.1Enter the main interface with a touch screen and select the detection mode (such as“Quick screening”or“Full analysis”）Enter basic information such as sample number and batch number. The system supports custom detection thresholds, and users can adjust the judgment range of imperfect particles according to the standards.

2. Sample processing and automatic detection

Sample preparation: Randomly sample from the wheat to be tested150Use a sampler to reduce the sample to a uniform state. Avoid using damaged or clumped samples to prevent blockages in the sampling chamber.

Automatic sampling: Open the sampling chamber at the top of the device and pour the sample into a dedicated tray to ensure a smooth distribution. After closing the warehouse door, click on the screen“Start detection”Button, the system automatically completes image acquisition, feature extraction, andAIanalyze

Result output: After the detection is completed, the screen displays the total amount of incomplete particles, as well as disease spot particles, mold particles, etc6Classify data and generate data that meets the criteriaGB/T 5494Standard testing report. Users can choose to print or export toUPlate.

Attention: Ensure stable operation of equipment

1. Operating standards and safety protection

Do not touch the lens: During the detection process, do not touch the camera and light source module with your hands or hard objects to avoid scratches or displacement that may affect imaging accuracy.

Anti static measures: When operating in a dry environment, it is recommended to wear an anti-static wristband to prevent static electricity from interfering with the circuit board.

Emergency stop: In case of sample jamming or abnormal noise, immediately press the emergency stop button on the side of the equipment, cut off the power, and troubleshoot.

2. Daily maintenance and regular calibration

Cleaning and maintenance: After each inspection, use a soft bristled brush to clean the residue in the sample chamber, and regularly wipe the surface of the camera with a dust-free cloth. Verify the uniformity of the light source using a standard color palette every month.

Model update: Manufacturers release quarterly updatesAIModel upgrade package, users need to go throughUImport the disk into the system to maintain the ability to identify new types of disease particles.

Inter station difference control: After long-term use, it is recommended to contact the manufacturer annually for equipment consistency calibration to ensure comparability of test results from multiple instruments.

3. Data Management and Compliance Requirements

Data backup: Regularly export detection records to the cloud or local servers to avoid data loss due to device failures.

Standard compliance: Strictly followLS/T 6402Request to control the temperature and humidity of the testing environment (temperature)20℃±5℃, humidity≤65%）To prevent moisture absorption or drying of the sample from affecting the results.

Through standardized operation and scientific maintenance, the wheat appearance quality analyzer can operate stably for a long time, providing reliable data support for food quality and safety.
