The low-temperature freezing transportation is convenient for long-distance transportation of related foods and is beneficial to long-period preservation of related foods. The food has more turnover areas in the cold chain transportation process, the areas are wider, and the involved personnel cover a plurality of links such as storage, transportation, terminal sales and the like. Any lack of control will result in a wide spread and spread of the covd-19 virus.
Due to the fact that the specificity of the cold chain food cannot be used for checking viruses one by one, particularly most cold chain foods are provided with independent outer packages, the cold chain foods cannot be detected one by one in a broken and detached mode, and the mode of simply detecting whether viruses exist outside the cold chain packaging box cannot accurately reflect whether viruses exist inside the packaging box. Therefore, on the basis of ensuring that the minimum independent package of the cold chain food is not damaged, whether the virus exists on the cold chain food is detected to the maximum extent, and the method has positive significance for the whole cold chain food industry. At present, the virus detection in the cold chain link basically depends on a manual mode, is carried out by sending the detection result to a designated laboratory for processing in a PCR or kit mode through manual sampling, reports and publishes the detection result again, and can not detect the cold chain foods in the same batch one by one in a sampling detection mode, so that a certain risk exists.

Further, after virus sampling is performed on the inside of the package 2, the virus detection method of the present invention further includes:
detecting viruses in the packaging box 2 based on internal virus sampling; the transfer mechanism 40 is started again until the package 2 is conveyed to the end thereof and stopped; the package 2 is pushed out from the transfer mechanism 40 to the storage area by the automatic blanking apparatus 60 so as to wait for the virus detection result.
When the virus detection result is negative, prompting that the vehicle can go out of the warehouse; when the virus detection result is positive, different treatment measures can be adopted according to different conditions that the virus is stained outside or the virus exists inside, meanwhile, related information can be uploaded for the first time to avoid artificial interference, and the occurrence of a report-hiding event is effectively avoided.
The invention forms the whole virus sampling chain between the automatic feeding equipment 50 and the automatic discharging equipment 60, does not need to participate manually in the whole process, forms a full-automatic control mode without participation, effectively avoids virus transmission, reduces the requirements on sites, and can be widely applied to the virus sampling work requirements of links such as cold chain food import, storage and the like.
By now it should be appreciated by those skilled in the art that while a number of exemplary embodiments of the invention have been shown and described herein in detail, many other variations or modifications of the invention consistent with the principles of the invention may be directly ascertained or inferred from the present disclosure without departing from the spirit and scope of the invention. Accordingly, the scope of the present invention should be understood and deemed to cover all such other variations or modifications.
