Fish Meal is used in one or more fish or fish Foot feet (fish head, fish tail, fish fin, internal organs, etc.) are raw materials, remove oil, dehydrated, and crush high protein feed. At the beginning of the 21st century, the total output of the world was about 7 million tons, the most output of the output was Chile, Peru, Japan, the United States, etc., and Norway, Denmark, South Africa, Iceland and Thailand were also the main fish powder producer. Among them, Chile and Peru have the highest yield, and the highest annual output is more than 1.3 million T (1989) and more than 120,000 T (1990), and its export volume accounts for 70% of total trade. my country’s fish powder is in late, with an annual output of about more than about more than 1 million, and is concentrated in the coastal provinces such as Shandong, Zhejiang, Guangdong, Fujian. my country’s fish powder is high, the annual use is nearly 1 million t, about 800,000 T of 800,000 tons per year, from Peru. 9PS China Feed Industry Information Network – Based on Feed, Serving Animal Husbandry

9PS China Feed Industry Information Network – Based on Feed, Service Animal Husbandry [ 123] The classification method of fish powder has three main types: 1 According to the source: domestic fish powder and imported fish powder (Peruvian fish powder, Chile fishmeal, South Africa fish powder, etc.). This classification method is rough, reflects the quality of the fish powder; 2 Powder is divided into: white fish powder and red fish powder. The white fish powder is mainly based on squid; the red fish powder is mainly with sardines, mackerel, and autumn knife. 3 According to the raw material site, it can be all fish powder (fish powder made from all the fish), strengthen fish powder (all fish powder + fish pulp), coarse fish powder (fish meal, with fish processing residue as raw materials), adjust Fish powder (all fish powder + coarse fish powder), mixed fishmeal (adjust fish powder + meat powder or feather powder), fish pink (fish pulp + adsorbent). The above classification method varies depending on the country, and my country’s feed industry is currently not standard, and many methods are in use.

Processing Technology

At home and abroad, more fish powder processing according to how much fish fat content, divided into ldquo; high fat fish rdquo; and ldquo; low fat fish rDQUO; Processing process. 9PS China Feed Industry Information Network – Based on Feed, Service Animal Husbandry

NBSP; The machining process of high fat fish is fatFish with high fat first, first perfinite, then dry the processing process of the powder. First, heating is heated with cooking or dry hot wind, and the fish body tissue protein is thermally degraded and the body fat is dissolved. The solid is then pressed into a spiral crushing method, and the solid is dried into a fish powder. The drying method is divided into dry hot air and steam method. The temperature of the dry hot air is different due to the heat source form, which can be unequal from 100 ~ 400 ¡ã C; the steam method is indirect heating, the drying speed is slow, but the fish powder is good. The whole fish has passed oil, soaked, dry, dried, crushing products, crude protein content is 50% to 60%. The squeezed juice is acidified, spray dried or heated to concentrate into a fish cream. Fish cream can also be produced with fish internal organs, and the raw materials are hydrolyzed, centrifuged, remove oil, and hydrolyzate. Produced fish cream can be sold directly, or the starch or glutinant can be used as a carrier and then sold, and the latter is called fish juice feed or mixed fish starch, and its nutritional value varies depending on the carrier. Now in processing, there are two methods of crushing and dipping. The imported fish powder is a leaching process, and the processing method is to dry the fishing fresh sea fish first, and then pulverized, then extract it with an organic solvent under high temperature and high pressure (also known as a degreasing process), and finally pulverized become. Fisheries companies in Peru, Chile and Ecuador produce fishmeal use this method. The domestic high-quality fish powder is multifacts the press process, which is processed.

China Feed Industry Information Network – Based on Feed, Serving Animal Husbandry NBSP; The processing of low fat fish is the relative content of fat fat. Low fish and other seafood processing processes. According to the type of the raw material, it is generally divided into all kinds of whole fish powder and mulli powder: all fish powder is carried out directly to the total fat content, directly heat and drying, losing part of the moisture, then performs degreasing, the solid foundation is dried to the moisture content of 18 %, Pulverized to make a fish powder. Usually, the whole fish is about 22kg of fish, and the crude protein content is about 60%. Miscellaneous fish powder is a product that will directly dry crushing of small butter fish, shrimp, crab, fish head, tail, fin, internal organs, but also known as dry powder, crude protein in 45% ~ 55%; or fish season First, the salted raw material is used, then desalted, then dry and pulverized. This fish is often used by desalting that is not thorough (more than 10% salt), and is improperly easy to cause a livestock and poison. 9PS China Feed Industry Information Network – Based on Feed, Serving Animal Husbandry
