Embodiment 1

[0013] Embodiment 1: 1. The raw materials that do not contain synthetic hormones, synthetic binders and antibiotics are mixed in proportion and pulverized to 0.05mm; 12%; ③ Send the hot and humid materials into the molding machine to make granules with a diameter of 1.2mm; ④ Put the granules into the sterilizer and sterilize them at 90□ for 20 minutes; ⑤ Blow the sterilized granules to 28□ with cold wind to make The weight content of moisture is 8%; ⑥ use a grading sieve to sieve the cooled pellet feed to remove broken grains and powder; ⑦ pack the pellet feed into the warehouse. ;

Embodiment 2

[0014] Example 2: ① Mix the various raw materials required for the feed in proportion and crush them to 0.3mm; ② Add 0.4Mp steam to the crushed product to make the moisture content of the material reach 18%; ③ Send the wet and hot materials into the molding In the machine, make granules with a diameter of 1.8mm; ④Put the granules into the sterilizer and sterilize them at 100° for 35 minutes; The final pellet feed is sieved with a grading sieve to remove broken grains and powder; ⑦Pack the pellet feed into the warehouse.

Embodiment 3

[0015] Embodiment 3: 1. Mix feed formulation raw materials not containing synthetic hormones, synthetic binders and antibiotics in proportion, and pulverize them to 0.15mm; content up to 15%; ③feed the hot and humid materials into the molding machine to make granules with a diameter of 1.5mm; Make the weight content of water be 10%; ⑥ After cooling, the granulated feed is sieved with a grading sieve to remove broken grains and powder; ⑦ Pack the granulated feed into the warehouse.

Abstract

The utility model discloses a production method for shrimp feed, which comprises the following steps: 1) the raw materials is mixed in proportion and crushed into 0.05 to 0.3 mm; 2) steam of 0.1 to 0.4 Mp is added into the crushed materials, so that the water content of the materials can reach 12 percent to 18 percent; 3) the hygrothermal materials is put into a forming machine so as to be made into particles with a diameter of 1.2 to 1.8mm; 4) the particles are arranged into a sterilizer for being sterilized for 20 to 50 min under the temperature of 90 DEG C to 100 DEG C; 5) after being sterilized, the particles are cooled into 28 DEG C to 40 DEG C by cold wind, and the water content is 8 percent to 12 percent; 6) the crushed particles or powder of the cooling particle feed are removed by a grading screen; 7) the particle feed is packaged and stored. By utilizing the invention, the water resistance and digestibility can be improved effectively, the harmful fungi and anti-nutritional factors can be removed, thereby the feed utilization rate can be increased, and the water pollution can be avoided; furthermore, the breeding shrimp will have good physique, so the shrimp aquaculture will truly become an industry of sustainable development.

Description

technical field [0001] The invention relates to a processing method of aquatic feed, in particular to a method for making compound feed with various shrimps as feeding objects. Background technique [0002] Shrimp, including various prawns, macrobrachium, crayfish and grass prawns cultured in freshwater and seawater, is a kind of aquatic product that people like. In addition to the delicious meat, its protein content is high, and the amino acids that make up the protein are balanced; the lipid content is low, and the cholesterol content of the edible part is lower. Shrimp is one of the varieties with the largest amount of foreign exchange among China's exported aquatic products. Most of the provinces and cities in China take shrimp as the breeding object. Shrimp are generally farmed in an intensive mode in China, and compound feed is the main food source for shrimp. However, due to the low quality of shrimp feed, shrimp growth has been slow, the incidence of disease is hi...
