Problems solved by technology

[0005] Although the problem of artificial breeding of large yellow croaker has been broken through, the feed for large yellow croaker fry still relies on imported or chilled miscellaneous fish paste and eel meal, which seriously pollutes water quality and causes many fish diseases in the later stage of breeding
At present, there is no microencapsulated feed for large yellow croaker fry in the domestic market

Embodiment 1

[0028] 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 extruder for puffing Pretreatment, puffing pretreatment and then superfine grinding to 200 mesh, the crushed material is the core material.

[0029] Then 1 kilogram of spirulina, 2 kilograms of fish oil, 0.1 kilogram of vitamins (vitamin A or vitamin B), 5 kilograms of gelatin, 91.9 kilograms of water are mixed and be 200 order homogeneously by colloid grinding fineness, make wall material coating with this; Microcapsule bait was made by spray drying method. When preparing microcapsule bait, the ratio of wall material (cured product) to core material is 1:100. The most commonly used method for making microencapsulated bait is the spray drying method. The air inlet and outlet temperatures are 200°C and 70°C respectively, and th...

Embodiment 2

[0032] 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 pulverize them to 80 meshes and enter the puffing machine for puffing Pretreatment, puffing pretreatment and then superfine grinding to 200 mesh, the crushed material is the core material.

[0033] Then 3 kilograms of spirulina, 5 kilograms of fish oil, 0.3 kilogram of vitamins (vitamin A or vitamin B), 9.7 kilograms of gelatin, 82 kilograms of water are mixed and be 200 order homogeneously by colloid grinding fineness, make wall material coating with this; Microcapsule bait was made by spray drying method. When preparing microcapsule bait, the ratio of wall material (cured product) to core material is 10:100. The most commonly used method for making microencapsulated bait is the spray drying method. The air inlet and outlet temperatures are 200°C and 70°C respectiv...

Embodiment 3

[0036] Mix 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), mix and pulverize them to 80 meshes and enter the puffing machine for puffing Pretreatment, puffing pretreatment and then superfine grinding to 200 mesh, the crushed material is the core material.

[0037]Then 2 kilograms of spirulina, 4 kilograms of fish oil, 0.2 kilograms of vitamins (vitamin A or vitamin B), 8.8 kilograms of gelatin, and 85 kilograms of water are mixed and passed through the colloid grinding fineness to be 200 mesh homogeneous, and make wall material coating with this; Microcapsule bait was made by spray drying method. When preparing microcapsule bait, the ratio of wall material (cured product) to core material is 5:100. The most commonly used method for making microencapsulated bait is the spray drying method. The air inlet and outlet temperatures are 2...

Abstract

The invention discloses a manufacturing method of a microcapsule forage of Pseudosciaena crocea fry with the size of less than or equal to 1.8cm. The manufacturing method comprises 1, providing a core material and a wall material, 2, carrying out core material mixing, puffing pre-treatment and superfine grinding, 3, carrying out mixing on the wall material and carrying out homogenization by a colloid mill, 4, preparing microcapsule bait from the core material and the wall material by a spray drying method, wherein a ratio of the wall material to the core material is (1-10): 100, and 5, carrying out secondary coating on the microcapsule bait to obtain the microcapsule forage, wherein in the coating, the coating comprises VC-phosphate and chitosan. A test proves that through the secondary coating, bait stability and suspensibility in water are effectively kept so that a wide application prospect of initial feed of Pseudosciaena crocea fry in seawater fish forage is obtained.

Description

[0001] This application is a divisional application of the parent application (original application number: 201210520178.X, the original application date is December 7, 2012, and the invention name is "a method for manufacturing microencapsulated feed for large yellow croaker fry ≤ 1.8cm"). technical field [0002] The invention relates to a formula and a manufacturing method of microencapsulated feed for large yellow croaker fry (≤1.8 cm). The invention belongs to the technical field of feed and feed additives. Background technique [0003] 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 Stoaceae and the genus Yellow Croaker, commonly known as "yellow croaker". It is mainly produced in China, Japan and North Korea. It is distributed in the south...
