Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of food detection and conveying, in particular to a food detection sample multi-channel conveying system. BACKGROUND

[0002] With the increasing prominence of food safety issues, food detection technology plays a crucial role in modern food industry. Food detection not only concerns the health of consumers, but also directly affects the reputation and market competitiveness of food enterprises. In the process of food detection, sample collection, conveying and processing are key links to ensure the accuracy and reliability of detection results. However, traditional food detection sample conveying systems have many shortcomings, such as low efficiency, sample cross-contamination, and low automation level, which seriously restrict the efficiency and accuracy of food detection. Therefore, it is necessary to develop a high-efficiency, reliable and automated food detection sample multi-channel conveying system. In order to improve the efficiency of sample conveying, some research institutions and enterprises have developed multi-channel conveying systems. This kind of system realizes the simultaneous conveying of multiple samples by increasing the number of conveying channels, which significantly improves the detection efficiency. However, the existing multi-channel system still has some problems in design and application. First, the structure of the multi-channel system is complex, the manufacturing cost is high, and the maintenance is difficult. Second, cross-contamination is easy to occur during sample conveying in the multi-channel system, especially when mixing samples between different channels. In addition, the existing multi-channel system has low automation level and still needs manual intervention, which increases the complexity of operation and the risk of human error.

Although this structure is simple and easy to operate, it wastes time and reduces efficiency when handling a large number of samples, which cannot meet the high-throughput demand of modern food detection.
