[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...
