How To Ensure Fish Feed Quality

The moisture content of pellet feed is a very important quality index, which directly affects the quality of pellet feed and the economic benefits of feed enterprises. Effective control of it is one of the key technologies to ensure the quality and safety of feed products. If the moisture content exceeds the specified standard, the pellet feed is prone to mildew and deterioration, which is not conducive to preservation, and will also reduce the content of nutrients. The moisture content also causes unstable product quality and affects the brand reputation of the product. In the process of feed processing, appropriate moisture content is beneficial to pelleting, reducing energy consumption and improving production. Therefore, in the production process of compound feed, in order to make the production run more smoothly, the energy consumption is lower, the particles are smoother and more uniform, and the final product meets the specified moisture content standard, it is necessary to carry out moisture control throughout the production process.  

Moisture control is to comprehensively control various factors according to different situations in the whole process of production, so that the final moisture content of the product can reach the expected target of the producer. The main factors that affect the final moisture content of feed products are: the moisture content of the feed material itself, the moisture change in the crushing stage, the liquid addition amount in the mixing stage, the moisture content of the steam, the level of conditioning, the size of the die hole and its thickness of the die, The air volume and drying time of the cooler, the packaging quality management, the influence of different climatic and environmental factors, etc. (Generally, the moisture of pellet feed after processing should not be higher than 12.5; but in the north, it can be not higher than 13.5. If pellet feed is processed in summer, due to the high ambient temperature, the optimum moisture content of finished pellets should not be higher than 12.5, otherwise susceptible to mildew deterioration).
