preparation example Construction

[0038] The present invention also provides a method for preparing rumen-passed Schizochytrium powder, the specific steps are as follows:

[0039] (1) After heating and melting the inner coating material beeswax, add natural compound antioxidants and mix evenly, then add Schizochytrium algae powder and mix evenly, melt and granulate in a high-speed shear mixing granulator, and pass through after cooling Sieve to obtain first-level coated particles;

[0040] (2) Dissolve cellulose acetate phthalate and glycerol monoacetate in an organic solvent as the coating material, and use a bottom-spray fluidized bed to coat the first-level coated particles. The finished product of chytrid algae powder.

Embodiment 1

[0042] Such as figure 1 As shown, pass the beeswax and Schizochytrium powder through a 40-mesh sieve respectively, take 550kg of beeswax and heat it to melt, and control the melting temperature at 70-80°C. After melting, add 300kg of Schizochytrium powder and 0.4kg of natural compound antioxidant to the Mix evenly in a high-speed shear mixing granulator, and the mixing speed is 400r / min;

[0043] During high-speed shear granulation, the stirring speed was increased to 800r / min, and at the same time, the slow gear of the shearing pulp was turned on for 5 minutes;

[0044] Enter circulating cooling water with a temperature of 8°C into the heating and cooling jacket, and obtain granules after cooling to room temperature. The granules are passed through a 16-40 double-layer vibrating sieve, and the collected sieve is the primary coated granule;

[0045] Dissolve 140kg of cellulose acetate phthalate and 9.6kg of glycerol monoacetate in 200L of organic solvent (a mixture of ethanol...

Embodiment 2

[0048] Pass the beeswax and Schizochytrium powder through a 40-mesh sieve respectively, take 400kg of beeswax and heat and melt it, and control the melting temperature at 70-80°C. After melting, add 500kg of Schizochytrium powder and 1kg of natural compound antioxidant to high-speed shearing and mixing Mix evenly in the granulator, and the mixing speed is 400r / min;

[0049] During high-speed shear granulation, the stirring speed was increased to 800r / min, and at the same time, the slow gear of the shearing pulp was turned on for 5 minutes;

[0050] Enter circulating cooling water with a temperature of 8°C into the heating and cooling jacket, and obtain granules after cooling to room temperature. The granules are passed through a 16-40 double-layer vibrating sieve, and the collected sieve is the primary coated granule;

[0051] Dissolve 80kg of cellulose acetate phthalate and 19kg of glycerol monoacetate in 200L of organic solvent (a mixture of ethanol and acetone at a volume r...

Abstract

The invention relates to a rumen protection schizochytrium limacinum powder. The rumen protection schizochytrium limacinum powder comprises a core material, an inner layer coating film for wrapping the core material and an outer layer coating film for wrapping the inner layer coating film, wherein the core material comprises schizochytrium limacinum powder; the inner layer coating film comprises hydrophobic beeswax and an antioxidant; and the outer layer coating film comprises glycerol monoacetate and a film forming material. The invention also provides a preparation method. According to the rumen protection schizochytrium limacinum powder and the preparation method thereof provided by the invention, double-layer coating treatment is performed, so that the rumen bypass rate of the schizochytrium limacinum powder in rumen is remarkably increased, and it is ensured that enteric coating substances are disintegrated in intestinal tracts after the schizochytrium limacinum powder enters theintestinal tracts, and therefore effective substances (DHA) in the schizochytrium limacinum powder can be released in the intestinal tracts and absorbed and converted by organisms; the effective utilization rate of te effective substances (DHA) is obviously improved; moreover, the antioxidant is added into the inner layer coating film, so that effective substances (DHA) in the schizochytrium limacinum powder are not easily influenced by environmental factors such as light, heat and oxygen, and the stability of the effective substances in storage and use can be ensured.

Description

technical field [0001] The invention relates to the technical field of animal husbandry, in particular to a rumen-protected Schizochytrium algae powder and a preparation method thereof. Background technique [0002] Docosahexaenoic acid, or DHA for short, is a polyunsaturated fatty acid that is very important to the human body. It has a variety of physiological functions: it can prevent cardiovascular and cerebrovascular diseases, such as lowering blood fat, preventing thrombosis, increasing blood vessel fluidity and protecting blood vessels; in addition, it can enhance memory, improve intelligence, delay brain function degeneration, and enhance human anti-cancer immunity and other functions. The human body cannot synthesize DHA by itself, and it must be supplemented through food absorption, such as eating deep-sea fish, nuts, and DHA products. [0003] With the improvement of living standards and the in-depth understanding of the physiological functions of DHA, people rea...
