Quality control key control points Quality control objectives: to ensure the quality of pellet feed products, including sensory quality, nutritional indicators, hygiene indicators and processing quality indicators.

  1. Requirements for the crushing fineness of raw materials: the feed crushing machine fineness of the raw materials that need to be crushed must reach more than 85% and pass through a 40-mesh sieve;
  2. Conditioning and tempering: The three elements of tempering are: moisture, temperature, and time; for fish feed, the moisture in conditioning and tempering must reach 14-15%, the temperature must be 90-100 degrees, and the time for conditioning and tempering in the conditioning room. The residence time needs to be controlled at more than 35-45 seconds;
  3. Material temperature inspection: the grain temperature should not exceed 5°C of room temperature;
  4. Particle water resistance test: for different particle sizes, the hard bottom standard is different, see the above picture (number of fish feed packaging processes)
  5. Monitoring of powder content and pulverization rate: the powder content of fish meal shall not exceed 4%, and the powder pulverization rate shall not exceed 1%;
  6. Quality control of packaging process: quality inspection of packaging, labeling, package weight, and sewing package.
