How to define a fish feed mill and its key quality control points?

 

 

If the fish feed produced by a fish feed factory is of poor quality (e.g., insufficient nutrition, impurities, or mold), the fish will get sick or even die after eating it, and fish farms will no longer buy it. Therefore, fish feed factory production lines have many "quality control" steps, monitoring the entire process from raw materials to finished products to ensure that the feed is up to standard.

 

 

 

1. Raw Material Incoming Inspection (Step 1: Preventing Problems at the Source) When raw materials (corn, fishmeal, soybean meal) arrive at the factory, they are sampled and inspected: Corn is checked for mold or sprouting (moldy corn cannot be used as it produces toxins); fishmeal is smelled for a fishy odor (a foul odor indicates spoilage); moisture content is measured (corn with a moisture content exceeding 16% must be dried, otherwise it is prone to mold). Unqualified raw materials are returned immediately and not allowed to enter the production line.

 

2. Grinding Process Inspection (Step 2: Ensuring Fineness) After grinding, the raw materials are sampled and inspected for fineness using a sieve (e.g., an 80-mesh sieve). The amount of coarse particles remaining on the sieve should not exceed 5%-too many coarse particles will result in uneven mixing later, making it difficult for fish to digest. If the fineness is insufficient, the sieve of the grinder is adjusted, and the grinding is repeated

 

3. Mixing Process Control (Step 3: Ensuring Uniform Nutrition) The mixed powder should be sampled and checked for uniformity. For example, measure the vitamin content of a handful of powder, then measure another handful. The difference between the two measurements should not exceed 5%. A large error indicates uneven mixing; some feeds may contain nutrients while others do not, resulting in uneven fish growth. If uneven mixing is found, extend the mixing time and stir for a while longer.

 

4. Forming Process Control (Step 4: Ensuring Pellet Quality) The finished pellets should be checked for three points: ① Size (e.g., for 4mm pellets, the error should not exceed 0.5mm); ② Hardness (pellets should not crumble easily when squeezed; those that crumble easily are unacceptable); ③ Water resistance (floating feed should float for at least 2 hours, sinking feed should sink and not disintegrate for 1 hour). Unacceptable pellets should be removed and recycled as raw materials.

 

5. Finished Product Control (Step 5: Final Inspection) Before packaging, finished feed samples must undergo a "fish palatability test": Feed a small amount of feed to small fish to see if they eat it (if they don't eat, it indicates poor palatability, possibly indicating a problem with the formula); observe the fish for 24 hours after feeding to see if they have diarrhea or become sick (problems indicate a potential problem with the feed). Simultaneously, moisture content (not exceeding 12%) and nutritional components (protein content must meet label requirements) must also be tested. Only after all tests are passed can the feed be packaged and shipped.

 

 

 

 

 

Fish feed factories maintain daily quality records, including the date of raw material delivery, the fineness of the powder, and the uniformity of mixing. This facilitates traceability-if a fish farm reports a problem with the feed, the factory can quickly pinpoint the source of the error and make timely improvements.
