Description

Technical Field

[0001] The present invention relates to the technical field of food detection, and in particular to a food microorganism rapid detection device for food detection. Background Art

[0002] Food testing refers to the process of systematic analysis and testing of food samples. Its purpose is to ensure the safety and quality of food and comply with relevant laws and regulations and standards, so as to protect people's food safety and consumption rights. The frequency and cycle of food testing are usually determined by factors such as the production scale, product type, process complexity and regulatory requirements of the food company. It is generally recommended that food companies or small workshops conduct testing every six months to promptly discover and deal with potential food safety hazards. E-commerce platforms and supermarkets may require a testing frequency of once or twice a year. If the product process changes or the source of raw materials changes, re-testing is required to ensure food safety. Food testing is one of the important means to ensure food safety and quality. Through scientific testing methods and strict testing processes, potential food safety hazards can be discovered and dealt with in a timely manner to protect the health and rights of consumers.

[0003] Food testing is mostly done by placing food samples in test tubes, adding reagents and shaking them, and then using testing instruments to analyze parameter information in the food samples. However, current food testing requires operators to manually shake the mixture of the reagent kit samples in the test tubes after placing food samples in test tubes and adding reagents. Manual shaking often relies on the operator's experience and feel, and it is difficult to ensure the standardization and consistency of each operation. Different operators or the same operator may perform operations differently at different times, which will affect the accuracy and reliability of the test results. Manual shaking requires operators to spend a certain amount of time and energy to complete, especially when dealing with a large number of samples. This manual operation method is inefficient, which may lead to an extension of the test cycle, increase test costs, and reduce overall test efficiency. Summary of the invention

[0004] In view of the above-mentioned existing food testing, when the food sample is placed in a test tube and the reagent is added, the operator needs to manually shake the mixture of the test kit sample in the test tube, and the manual shaking often depends on the operator's experience and hand feel, and it is difficult to ensure the standardization and consistency of each operation. There may be differences in the operations performed by different operators or the same operator at different times, which will affect the accuracy and reliability of the test results. In addition, the manual shaking requires the operator to spend a certain amount of time and energy to complete. Especially when processing a large number of samples, this manual operation method will appear inefficient, which may lead to the problem of extending the detection cycle, increasing the detection cost, and reducing the overall detection efficiency. The present invention is proposed.

[0005] Therefore, the purpose of the present invention is to provide a food microorganism rapid detection device for food testing, the purpose of which is to use automated shaking operation to process multiple groups of test tubes at the same time, significantly improving the detection efficiency. Compared with manual operation, the automatic shaking operation can complete the shaking work of a large number of test tubes in a shorter time, thereby shortening the detection cycle and reducing the detection cost. At the same time, the automatic shaking operation has higher operational standardization and consistency. By precisely controlling the frequency, amplitude and time of oscillation, it can ensure that the samples and reagents in each group of test tubes can be fully mixed, thereby improving the accuracy and reliability of the test results.

[0016] Beneficial effects of the present invention:

[0017] 1. The present invention can start the motor to drive five groups of rotating cross bars to rotate, and can synchronously perform intermittent knocking on the bottoms of multiple groups of placement tubes, thereby driving the placement tubes and test tubes to vibrate up and down, and then can mix and shake the samples and reagents in the multiple groups of test tubes, which can significantly improve the detection efficiency.

At the same time, the fixing and unlocking operations of the fixing component are fast and convenient. When a large number of samples need to be processed, the detection process can be significantly accelerated, the detection cycle can be shortened, and the operator can easily complete the operation, reducing the difficulty and fatigue of the operation.
