Description

Technical Field

[0001] The utility model relates to the technical field of agricultural product detection, and more specifically, to a grain tryptophan sampling and detection device. Background Art

[0002] The grain tryptophan sampling and detection device is a device specially used to sample and detect the tryptophan content in grains. It combines sampling and detection technologies and can quickly and accurately analyze the tryptophan level in grains, which is of great significance for food quality control and nutritional assessment.

[0003] During the existing grain quality inspection, it is necessary to sample the grain in the granary. The common sampling method is to take out a part of the grain on the surface, which is not convenient for sampling deep inside the granary. Since the grain is stored at different depths in the granary, the quality of the grain and the moisture content are also different, so it is necessary to sample the grain piles at different depths.

[0004] After searching, the Chinese patent with publication number CN219935306U discloses a grain detection sampling device. The utility model uses a sampling rod movably inserted through a plug connected to the sampling barrel. By pulling the sampling rod, the baffle is driven to move along the axial direction of the sampling barrel, thereby realizing the opening and closing of the sampling port. By pulling the position of the sampling rod, the opening and closing status of the sampling port can be accurately judged, ensuring that the sampling port is fully opened during sampling and completely closed after sampling is completed, thereby effectively improving the reliability and accuracy of sampling.

[0005] However, when the sampling device is actually used to detect tryptophan in grains, the grains need to be taken out of the sampling device for pretreatment and then sent to the tryptophan detection device for detection of tryptophan in the grains, which affects the efficiency of grain detection.
