Problems solved by technology

However, this processing method has the following defects: 1) it may increase the pulverization rate of the pellets; 2) various active substances adhere to the surface of the feed pellets, which are easily peeled off during the transportation of the feed, and the feed active substances are lost; 3. ) Active substances adhered to the surface are more easily affected by light and oxidation, resulting in greater loss during storage
So far, there is no very effective solution to the problem of nutrient loss during feed extrusion

Embodiment 1

[0055] Example 1 Preparation of Feed Granules

[0056] First mix 14.5kg of corn gluten powder, 15.5kg of fish meal, 22.3kg of soybean meal, 0.5kg of multivitamins, 2.5kg of minerals, 0.5kg of lysine, and 0.2kg of methionine, and prepare it at room temperature (10°C-35°C). Particles (spheres) with an average particle size of 10mm are used as the dispersed phase, and its main components are protein, fiber, amino acid, vitamin, etc.

[0057] Mix 30.0kg of flour, 1.0kg of soybean oil, 1.0kg of fish oil, and 2.0kg of phospholipid to form a continuous phase whose main components are sugar, starch, fat and other components.

[0058] The above-prepared dispersed phase and continuous phase were mixed evenly, and 10 kg of water was added to adjust the water content, and then extruded and granulated through a ring die at 130° C. to obtain feed granules. The feed granules have a columnar structure, a circular cross section, an axial length of 100 mm, and a radial average diameter of 15 m...

Embodiment 2

[0082] Example 2 Preparation of Feed Granules

[0083] First mix 20kg of rice bran, 16kg of bran, and 5kg of glucose evenly, and prepare 5mm particles (spheres) at room temperature (10°C-35°C) as dispersed phase 2-1, whose main components are starch, reducing sugar, etc.

[0084] Mix 0.1 kg of lysine, 0.1 kg of methionine, 0.6 kg of multivitamins and 1 kg of bone meal, and prepare 1 mm particles (spheres) at room temperature (10°C-35°C) as the dispersed phase 2-2.

[0085] Mix 3kg of fish meal, 20kg of bean cake, 15kg of peanut cake, and 10kg of corn gluten powder to prepare a continuous phase whose main components are protein, amino acid, fiber, etc.

[0086] The dispersed phase 2-1, dispersed phase 2-2 and continuous phase prepared above were mixed evenly, and 10 kg of water was added to adjust the water content, and pelletized by twin-screw extrusion at 140° C. to obtain feed pellets. The feed granules have a flake structure, a pentagram-shaped cross section, an axial leng...

Embodiment 3

[0089]Example 3 Preparation of Feed Granules

[0090] Mix 15kg of fish meal, 10kg of meat and bone meal, 3kg of brewer’s yeast, and 5kg of corn gluten powder evenly, and prepare 5mm particles (polyhedron, frustum or cylinder) at low temperature (36°C-75°C) as dispersed phase 2-1. Its main component is protein.

[0091] Mix 2.5kg pine needle powder, 6.85kg black locust leaf powder, 6kg seaweed powder, 0.15kg vitamin C phosphate, and 0.5kg choline chloride evenly, and prepare 2mm particles at room temperature (10°C-35°C) as the dispersed phase 2-2, its main components are fiber, polysaccharides, trace elements and so on.

[0092] Mix 15kg of dehulled soybean meal and 10kg of rapeseed meal evenly as dispersed phase 2-3.

[0093] Mix 25kg of flour and 1kg of soybean oil evenly to make particles with an average particle size of less than 1mm as the continuous phase, and its main components are starch, oil, etc.

[0094] The dispersed phase 2-1, dispersed phase 2-2, dispersed pha...

Abstract

The invention relates to the field of feed processing and especially relates to feed granules and a preparation method of the feed granules. The feed granules includes a continuous phase and a dispersed phase; the dispersed phase is a particle state surrounded by the continuous phase; nutrients capable of reacting in the feed granules are placed in different phases, or placed in different dispersed interior-phases of the dispersed phase; and the raw materials of the dispersed phase comprise a mixture composed of following one or two or more nutrients: heat-sensitive nutrients, easily-oxidized nutrients as well as nutrients, as a catalyst, utilized in a reaction in which bad flavors can be produced. The feed granules provided by the invention are capable of reducing nutrient losses and browning reactions during feed extrusion.

Description

technical field [0001] The invention relates to the field of feed processing, in particular to a feed pellet and a preparation method thereof. Background technique [0002] Feed refers to substances that can be eaten by animals and provide one or more nutrients. Feed includes all kinds of natural feed raw materials, as well as products processed from various raw materials, such as additive premixes, concentrated feeds and complete feeds. Among them, the full-price feed refers to the nutritionally complete compound feed, which contains energy, protein, mineral feed and various feed additives. All kinds of nutrients are complete, the quantity is sufficient, and the proportion is appropriate, which can meet the production needs of the breeding objects, and can be directly used for production, and generally no need to supplement any feed. In the complete feed, energy feed includes corn, wheat, rice, barley, etc.; protein feed includes plant protein such as cakes and by-product...
