Description

Technical Field

[0001] The present invention relates to the technical field of feed additive sampling inspection, and in particular to a feed additive sampling inspection system and a use method thereof. Background Art

[0002] Feed additives refer to small or trace substances added during the production, processing and use of feed. They are used in small amounts in feed but have significant effects. Feed additives are raw materials that must be used in the modern feed industry. They have obvious effects on strengthening the nutritional value of basic feed, improving animal production performance, ensuring animal health, saving feed costs, and improving the quality of livestock products.

[0003] After the production of feed additives, they need to be sampled and inspected to ensure the quality of feed products. The existing feed additive sampling method is mainly manual sampling, which consumes labor and has low efficiency. Workers are prone to contact with feed additives during the sampling process and cause pollution. In order to facilitate random sampling of feed additives, a feed additive sampling system and a method of using the same are proposed. The system is connected to the discharge port of the feed additive production line and can disperse the feed additives discharged from the discharge port so that the discharged feed additives can be evenly dispersed to ensure the uniformity of the sample for sampling. Multiple groups of feeding channels are provided, and the feed additives in the multiple groups of feeding channels can be sampled in turn. A sample collection component is provided, and multiple groups of sample samples can be collected in turn. The staff can take out the multiple groups of sample samples for subsequent inspection. The entire sampling process can ensure the randomness and uniformity of the samples, and the overall outer wall environment of the sampling method does not contact the produced feed additives, which has better safety. Summary of the invention

The feed additive can be effectively dispersed and evenly sampled, and the sampled samples can be evenly collected. The staff does not need to contact the samples as a whole, which can effectively ensure the safety of the samples and prevent contamination of the finished feed additives.

[0006] The method of use includes the following steps:

[0007] S1: The feed additive production line is connected to the feed additive production line, so that the finished feed additive can be transported to the scattering box.
