Granville sturgeon feed

Macrobrachium due to individual large, fast growth, easy feeding, etc., has been in many provinces, autonomous regions to promote the culture, but its pellets in addition to need to have a comprehensive and balanced nutrition, but also has good stability in water, and therefore inland provinces and autonomous regions in the promotion of Macrobrachium breeding process, feed production has been a major problem. This paper introduces a common use of fish feed pellets production line processing technology giant river prawn pellets, for reference. 1, giant river prawn pellets production process includes the following steps: raw materials blasting - smash - ingredients - Mixed - vapor quenched - granulating - Dry Cooling - packaging 2, giant river prawn protein content of feed material composition is 30% to 40 %, the formula fish meal, soybean meal and other protein feed should be accounted for a higher proportion; also rich in calcium, phosphorus and other minerals and vitamins, especially Vc dosage should reach 50O-1000 mg / kg. In addition, the amount of flour or flour in the recipe should be more than 10%. And should reduce the bran or other fiber-rich crude material usage. 3, grinding mill and ingredients can be used hammer mill, sieve aperture of 1.0 or 1.2 mm is appropriate. For stubborn jaw pulverized material available and pulverized, it should pass through a 40 mesh screen material crushed. For some small or trace amounts of additional ingredients such as trace elements, vitamins or coarse scales should be used for weighing scales. 4, mixed with granulation mixing equipment should be horizontal ribbon mixer, mixing time 4--6 minutes is appropriate. Granulation equipment can ring die pellet mill, ring touch 1.5-2 mm aperture shrimp, prawn 2.5 mm. When granulated feed motor speed of 300 rev / into appropriate, quenching the vapor pressure should be used 0.4 trillion Dayton, quenching temperature to 95 degrees is appropriate. Drying cooling particles often with vertical coolers, cooling the pellets can be carried out as long as the size appropriate packaging or production applications. It should be noted that some coastal shrimp feed mill for the production of material, specifically with the post-curing process, namely pellets are squeezed out after the first pellet mill heated, then cooled, this will definitely improve rosenbergii pellets of water resistance.
