Embodiment 1

[0015] Melt 470g of hardened rapeseed oil and 30g of mixed tocopherol mixture, mix them evenly, cool the mixture to solidify, crush the solid mixture into fine particles, and thus obtain fine particles with a melting point of 40°C and an average particle size of 10 μm. Powdered coating material granules.

[0016] 150g of the above-mentioned coating material particles and 450g of vitamin K core material particles with an average particle size of 200 μm are put into a high-efficiency powder mixer together, and the weight content of vitamin K in the vitamin K core material particles is 50%. The temperature of the cooling jacket was adjusted to 25 degrees, and the above-mentioned materials were processed in the above-mentioned mixer for 20 minutes at a peripheral speed of 10 m / s. That is to get the well-embedded vitamin K preparation we need.

Embodiment 2

[0018] 920g of hardened soybean oil, 150g of palm oil and 80g of d-delta tocopherol are melted together to form a homogeneous mixture, the mixture is cooled and solidified, and the solid mixture is pulverized to make a melting point of 64.8° C. and an average particle size of 25 μm as a fine powder coating particle.

[0019] 300g of the above-mentioned coating material particles and 300g of vitamin K core material particles with an average particle size of 120 μm are put into a high-efficiency mixer together, and the weight content of vitamin K in the vitamin K core material particles is 60%. The temperature of the cooling jacket was adjusted to 20 degrees, and the above-mentioned materials were processed in the above-mentioned mixer for 15 minutes at a peripheral speed of 13 m / s. That is to get the well-embedded vitamin K preparation we need.

Embodiment 3

[0021] Melt 290g of hardened rapeseed oil, 460g of hardened soybean oil and 40gd-α and 15gd-δ tocopherol together to form a homogeneous mixture, cool the mixture to solidify, crush the solid mixture into a fine powder with a melting point of 68.4°C and an average particle size of 50μm Coating granules.

[0022] 200g of the above-mentioned coating material particles and 800g of vitamin K core material particles with an average particle size of 450 μm are put into a high-efficiency mixer together, and the weight content of vitamin K in the vitamin K core material particles is 70%. The temperature of the cooling jacket was adjusted to 22 degrees, and the above-mentioned materials were processed in the above-mentioned mixer for 15 minutes at a peripheral speed of 15 m / s. That is to get the well-embedded vitamin K preparation we need.

Abstract

The invention relates to a preparation method of a coated vitamin K preparation used for animal feeds. Currently, the effectiveness of vitamin K is rapidly reduced, so as not to be in favor of healthy growth of animals. The method comprises mixing a coating material and vitamin K, melting, cooling and solidifying to obtain a uniform solid mixture; pulverizing the solid mixture to fine powder-like coating granules with mean particle size of 10-50 mum; and mixing the coating granules and vitamin K core granules at a weight ratio of 1:(1-4) in a powder mixer equipped with a cooling jacket (below 25 DEG C), and treating at a peripheral speed of 10-15 m/s for 15-20 to obtain the vitamin K preparation. The vitamin K preparation prepared by the inventive method has increase content of vitamin K and reduced application dose, and can generally reduce the feed cost.

Description

technical field [0001] The invention belongs to the technical field of feed additives, in particular to a method for preparing a coated vitamin K preparation for animal feed. Background technique [0002] Vitamin K has been widely used in animal feed as a vitamin K supplement and to prevent congestive diseases and promote healthy bone growth. The stability of natural vitamin K is very poor, and the salt of vitamin K3 has good stability in the multivitamin premix without trace mineral elements, but the salt of vitamin K is easily destroyed under alkaline conditions. Therefore alkaline or slightly alkaline minerals should not be mixed with vitamin K salts. The stability of vitamin K salts can also be reduced due to the presence of choline chloride or higher water content in the feed. Stirring and mixing during feed granulation, high temperature, extrusion, etc. will increase the damage to vitamin K3 salt. Due to the presence of atmospheric humidity, light and metal ions in ...
