Foreword DB3 aquaculture is the fastest growing food industry in the world. According to UNFOC (FAO) 1998, the People’s Republic of China is the world’s largest aquatic products producer. To make aquatic animals grow faster, we must first understand its nutritional needs, and understand the feed production technology. Of course, genetics, physiology, biochemistry and farming technology are also very important. Aquatic feed plus technology has progressed rapidly in the past 20 years, and for example, aquatic feed production is almost completely converted from steam granules to extrusion. One of the pluralities of extrusion is to make a floating feed, so that farmers can estimate how much fish eat according to the amount of feed remaining in the water. Excessive feeding will not only cause waste, increase production costs, but also pollute the environment. Although the extrusion will reduce the utilization of some nutrie in the feed, it is still the first choice for the farm. The farmer can see the fish’s feeding situation, you can better feed, master the fish. This paper describes the production process of aquatic feed, and proposes some suggestions. DB3 Service Animal Source: United Nations Food and Agriculture (FAO) DB3 1 Aquatic Feed Factory Design DB3 – Feed feedstocks are stored in a crushing shop silo or raw material warehouse through the receiving system. Feed raw materials can be pulverized separately, and then batch bubbles with vitamin premix, mineral premix, feed additives, and liquid feedstocks (such a crushing system in front of North America). The system requires more storage bins, transportation, and storage are not as good as crushing. It is also possible to combine the raw materials to make a batch of ingredie (this after the comminution system is very common in Europe), and then the vitamin premix, mineral premix, feed additive and liquid feedstock are batch, stirred together. The post-pulverization system is well suited to handle high oil content (such as fish powder and poultry powder). Such raw materials can also be mixed with cereal raw materials such as oils such as wheat and solve, which can alleviate the inclusion of oil-containing raw materials when crushing. The post-pulverization system is provided with a buffer storage, which is sent from the buffer position to the mixer, and then formed. This system is a ted by most aquatic feed processing pla because the feed plant uses a variety of by-products as a feed raw material, which is easily uniform as the raw material is uniform, respectively, and is easily uniform. After stirring, the batch ingredie were stirred, stirred, stirred, and then sent to the workshop silicon for granulation or extrusion. DB3 serving the animal husbandry processing shrimp feed, the pulverized raw materials from the workshop silo should pass through a double or three-layer pre-regulator, the purpose is to extend the material retention time, in the system Put steam before grain. The steam contains heat and water, heats the temperature rise, reaches the temperature conditions required to make the starch, wheat gluten, the temperature conditions required. There is no suitable time, temperature and moisture, the starch cannot be gear, the gluten cannot be formed. Shrimp is slowly eating slowly, becauseThis shrimp feed should be as stable as possible, and the disintegration of dissolving in the water is long. Figure 2 shows the effect of shrimp feed water on water stability indicators (WiTerStabilty Index, Abbreviation WSI) (Cheng Zongjia et al, 2002). The longer the feed time of feed, the greater the amount of feed damage. Figure 3 shows the effect of the temperature of the material moisture and the temperature of the machining, the effect of shrimp feed WSI by meat mill (Cheng Zongjia et al, 2002). It will be clear from Figure 3, with a meat grunmat, a shrimp feed, WSI, produced under 100 ¡ã C, 40% moisture conditions, and the highest. DB3 Serving Livestock by Pre-regulator Treatment, Press the granulation in the granulator, and then through a granulated mature, there are more steam to reach the shrimp feed surface Strengthen ripening. The final particles were dried to a suitable moisture (less than 10%) by drying / cooler to safely store. DB3 Most fish feed is a floating feed or slow sinking feed, which is made of extrusion technology. The extrusion process is also the same as granulation, and the material of the silo is in the extruder, and the suitable machining conditions are created in a suitable machine, screw and shear lock, and form a fish feed. The material is extruded into a certain shape and cut into a certain size, and is dried to the drying / cooler drying. The farm has the best benefits available from extrusion processing DB3 is improved feed efficiency. Squeezing processed fish feed, its persistence and water stability are better than steam granulation or cold extruded products. Squeeze processing is also advantageous to add a lot of fat in some formulations, such as high energy squid and squid feed. For such fish, high-energy feed can save diet proteins and improve feed efficiency. The feed efficiency of young rainbow trout feed can reach 1.0g feed / g weight, the feed efficiency of the entire production cycle is about 1.2G feed / g weight, in the United States, the rainbow trout is usually about 0.75kg. DB3 drying / cooling, the screen is broken. If you need to coat the grease from the granules, it should be sprayed with heat from the dryer from the dryer. Then, send the particle feed to the scattered bin waiting to be dissatisfactory, or put it into the packaging bag. DB3 2 Praveling DB3 – Based on Feeds, Most raw materials for the production of animal husbandry for aquatic feed should be comminuted (lower granularity). The purpose of pulverization is to obtain materials suitable for fabricating high quality feed and is most suitable for animal digestion (Martin, 1983). Stevens (1961) poi out that the raw materials are pulverized with the following reasons: pulverization can increase the exposure surface area of the material; make the material easier to digest; when processing; the pulverization can improve the uniformity of the stirring, especially for young animals with small feeding capacity Crushing also helps granulation and extrusion. DB3 Making Fish and Shrimp Feed, especiallyShrimp feed, it is necessary to make raw materials, which is made of pellet feed to better water stability, and can enhance animal production performance. Palaniswamy and A1i (1991) were studied, and the raw material particle size was reduced to 500, 420, 300, 250, 210, 50 mu; m (micrometers, the same), and the results showed that the water stability of the obtained particulate feed was 210 Mu; M is most Okay. When the Penaeusindicus is born with the raw material particle size of 210 mu; M grain feeding, the growth rate is the fastest, the feed conversion is the best, and the digestibility is also the highest. Obaldo et al. (1998) Put a raw material particles of a shrimp day from 603 Mu; m to 586, 52L, 408, 272, 124, 69 Mu; M, finding a feed made of 124 MU; M raw material particles to increase particles. Water stability, particle persistence, starch transformation ratio, real weight and weight gain of shrimp. Popular feed, poor water, will produce a lot of broken, not only waste, but also increase production costs, and pollute the environment. However, the raw material pulverization increases the electricity consumption and the water during the production process, and the powder loss is increased. DB3 Crusher and Roll Working For coarse grains, 300-1200 mu; m fragmented granules, high efficiency. When using a hammer pulverizer, the screen is easily blocked. When the high-fat raw material such as fish powder and poultry, it is better to be smashed into some cereals. When the pulverizer is machined, a sifter should be added to the pulverized process, and the coarse granules return to the pulverizer further crush, which can stably obtain the required particle size.
