Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of irradiation processing equipment, in particular to an anti-contamination tooling for sampling food after irradiation. Background Art
[0002] Food and agricultural products can effectively kill microorganisms in products after irradiation. In the actual production of irradiation processing, especially high-energy electron beam irradiation, the production site environment cannot be under purified air conditions, that is, the microorganisms in the environment cannot be controlled. Irradiated products usually need to be sampled again for testing. Sampling is usually carried out at the irradiation site. Therefore, the sampling process should try to prevent secondary contamination of the sampling. The current sampling mechanism is prone to contamination if it is not transferred to the storage mechanism in time after the sampling is completed. In addition, it is inconvenient to clean the inside of the sampling mechanism, which has certain disadvantages. To this end, we propose an anti-contamination tooling for sampling food after irradiation. Utility Model Content

[0011] Compared with the prior art, the utility model has the following beneficial effects: the anti-contamination tooling for sampling food after irradiation has a simple and reasonable structural design and is highly practical. By setting up the matched structures such as the barrel, barrel cover, positioning seat, pull rod, sampling head, first limiting screw, etc., the sampling head can be effectively protected by the barrel. When performing the sampling operation, it is only necessary to loosen the first limiting screw to remove the sampling head from the barrel through the pull rod, and then insert the sampling head into the food, and sample the inside of the product packaging by rotating the handle. After sampling, The sample continues to be collected into the cylinder and sealed with a plug, so that the sample is placed in a closed sampling container and transferred to a sterile sampling bag, effectively preventing secondary contamination of product sampling after irradiation and ensuring the sampling quality. By arranging structures such as a convex rod, a connecting rod, a groove, a second limiting screw and a connecting hole, it is convenient to connect and combine the pull rod and the connecting rod, and at the same time, the two can be easily disassembled. At this time, the sampling head can be taken out from the bottom of the cylinder, which is convenient for cleaning and maintenance of the structure, solving the problem of inconvenient cleaning inside ordinary sampling mechanisms.
