Background
The prawns, known as oriental shrimps, are also called Chinese shrimps and penaeus monodon. Arthropoda, class Mirabilis, order decapod, family Penaeidae, genus Penaeus. Prawns belong to a large individual, commonly known as prawns. The prawn is mainly bred in a mixed breeding mode, such as mixed breeding with sea cucumbers in the north and mixed breeding with clams in the south, the yield is higher, the prawn and shellfish frozen fresh feed is basically fed, and no special compound feed for the Japanese prawn is used. On one hand, the intensive and large-scale development of the prawns is limited, and on the other hand, the feeding of the chilled food wastes a large amount of fish, shrimp and shellfish resources, causes environmental pollution and causes the frequent occurrence of diseases such as white spot disease of the prawns. In addition, the existing prawn feed production device can only mix, extrude, granulate and dry all raw materials, and the icy and fresh raw materials in the prawn feed, such as fishes, shrimps and shellfishes, can not be ground into powder when being extruded and granulated, so that the subsequent extrusion and granulation processes of the feed are severely restricted.
The invention with the application number of CN2019111311454 discloses a compound feed capable of replacing a chilled feed to culture Japanese prawns, which comprises the following components in parts by weight: 10-60 parts of fish meal, 1-10 parts of antarctic krill powder, 1-6 parts of silkworm chrysalis powder, 1-3 parts of cottonseed meal, 1-5 parts of intestinal membrane protein powder, 1-10 parts of 46% soybean meal, 10-20 parts of high gluten flour, 1-3 parts of cuttlefish paste, 1-10 parts of enzymolysis fish soluble paste, 1-3 parts of scallop powder, 1-4 parts of beer yeast powder, 1-4 parts of soybean phospholipid oil, 1-3 parts of squid oil and 1-2 parts of a multivitamin multi-mineral mixture. The compound feed disclosed by the invention has balanced nutrition, can meet the nutritional requirements of Japanese prawns, has a good food calling effect, but has a poor sinking effect, and can be decomposed if not eaten by the prawns in time after being put into water, so that the water quality is seriously influenced. Also, for example, the invention with the application number of CN201811565864.2 discloses a method for producing a prawn feed, which is prepared from the following raw materials, by weight, 6% of rice bran, 3% of brewer's grains, 0.28% of earthworm powder, 5% of fly maggot powder, 6% of fish meal, 0.2% of pig blood, 0.2% of dandelion, 0.25% of purslane, 8% of rapeseed cake, 16% of duckweed, 16% of mulberry leaves, 4% of seaweed, 4% of egg pupa powder, 0.06% of betaine, 0.01% of bile acid salt, 12% of wheat middling, and 19% of cassava raw powder through the procedures of conveying, cleaning, crushing, mixing, tempering, extruding and puffing. Therefore, aiming at the defects of the existing prawn feed, the design of the compound feed for the prawns, the preparation process and the preparation device thereof, which can solve the technical problems, are technical problems to be solved.
