Embodiment 1

[0026] Mix 580 kg of imported fish meal, 120 kg of soybean meal, 40 kg of rapeseed meal, 30 kg of squid liver paste, 220 kg of flour, and 10 kg of minerals (containing iron, manganese, zinc or phosphorus), mix and pulverize them to 80 mesh and enter the puffing machine for puffing Pretreatment, puffing pretreatment and then superfine grinding to 200 mesh, the crushed material is the core material.

[0027] Then 1 kg of spirulina, 2 kg of fish oil, 0.1 kg of vitamins (vitamin A or vitamin B), 5 kg of gelatin, and 91.9 kg of water are mixed and homogenized through a colloid mill with a fineness of 200 mesh, and used as a wall material coating; Microcapsule bait was made by spray drying method. When preparing microcapsule bait, the ratio of wall material (cured material) to core material is 1:100. The most commonly used method for making microcapsule bait is the spray drying method. The air inlet and outlet temperatures are 200°C and 70°C respectively, and the moisture content a...

Embodiment 2

[0030] Mix 540 kg of imported fish meal, 150 kg of soybean meal, 40 kg of rapeseed meal, 35 kg of squid liver paste, 220 kg of flour, and 15 kg of minerals (containing iron, manganese, zinc or phosphorus), mix and crush them to 80 meshes and enter the extruder for puffing Pretreatment, puffing pretreatment and then superfine grinding to 200 mesh, the crushed material is the core material.

[0031] Then 3 kg of spirulina, 5 kg of fish oil, 0.3 kg of vitamins (vitamin A or vitamin B), 9.7 kg of gelatin, and 82 kg of water were mixed and homogenized through a colloid mill with a fineness of 200 mesh.

[0032] Use this as wall material coating; use spray drying method to make microcapsule bait. When preparing microcapsule bait, the ratio of wall material (cured material) to core material is 10:100. The most commonly used method for making microcapsule bait is the spray drying method. The air inlet and outlet temperatures are 200°C and 70°C respectively, and the moisture content a...

Embodiment 3

[0035] Mix and grind 500 kg of imported fish meal, 155 kg of soybean meal, 50 kg of rapeseed meal, 45 kg of squid liver paste, 230 kg of flour, and 20 kg of minerals (containing iron, manganese, zinc or phosphorus) to 80 meshes and enter the extruder for puffing Pretreatment, puffing pretreatment and then superfine grinding to 200 mesh, the crushed material is the core material.

[0036] Then 2 kg of spirulina, 4 kg of fish oil, 0.2 kg of vitamins (vitamin A or vitamin B), 8.8 kg of gelatin, and 85 kg of water were mixed and homogenized through a colloid mill with a fineness of 200 mesh.

[0037] Use this as wall material coating; use spray drying method to make microcapsule bait. When preparing microcapsule bait, the ratio of wall material (cured material) to core material is 5:100. The most commonly used method for making microcapsule bait is the spray drying method. The air inlet and outlet temperatures are 200°C and 70°C respectively, and the moisture content after drying...

Abstract

The invention discloses a preparation method of microcapsule feed smaller than or equal to 1.8cm for rhubarb fry, which comprises the following steps: (I) the core material of the formula comprises imported fish meal, bean pulp, rapeseed meal, cuttlefish liver paste, flour and mineral substances, and the wall material of the formula comprises spirulina, fish oil, vitamins, gelatin and water; (II) the core material of the formula is subjected to puffing pretreatment and superfine grinding; (III) the wall material of the formula is homogenized through a colloid mill; (IV) microcapsule bait is prepared by a spray drying method; (V) the proportion of the wall material coating to the core material is (1-10):100; and (VI) the ratio of vitamin C polyphosphate to a chitosan solution for secondary coating is (2-10):100. Experiments prove that the main raw material adopted by the invention is easy to digest and absorb since the microcapsule bait prepared by puffing pretreatment and microcapsule granulation has good food attraction; and moreover, the secondary coating technology can keep the stability and suspension property of bait in water more effectively, thus a broad application prospect of the rhubarb fry initial feed in seawater fish feed is developed.

Description

technical field [0001] The invention relates to a formula and a manufacturing method of microencapsulated feed for large yellow croaker fry (≤1.8cm). The invention belongs to the technical field of feed and feed additives. Background technique [0002] Large yellow croaker is the fish with the highest single output in seawater cage culture in my country, and has been identified as one of the six most advantageous export aquatic products in my country by the Ministry of Agriculture. The large yellow croaker belongs to the family Scroakeridae and belongs to the genus Yellow Croaker, commonly known as "yellow croaker". It is mainly produced in China, Japan and North Korea. It is distributed in the southern part of the Yellow Sea, the southwestern coast of North Korea, the East China Sea and the northern coast of the South China Sea to the east of the Qiongzhou Strait. It is a kind of carnivorous fish distributed in low- and middle-latitude, warm-water shallow seas near the bot...
