[0002] In food inspection and testing, it is often necessary to collect multiple samples for a production stage or a batch of products. When selecting samples for testing, it is often necessary to ensure that the sample selection is absolutely random to avoid interference from human factors on the test results. There cannot be any human or external factors intervening in the sample selection. Therefore, random selection can effectively ensure randomness, but this method is generally performed by experimenters or other personnel, and still has a certain risk of intervention, and absolute randomness cannot be achieved. For this reason, we propose a sampling box for food inspection and testing. Utility Model Content
