Embodiment 1

[0028] A kind of coated calcium chloride, the concrete steps of its preparation method are as follows:

[0029] (1) Dissolve 600g of calcium chloride in water to prepare a saturated aqueous solution of calcium chloride, take 100g of silicon dioxide and put it into a granulation fluidized bed, atomize it with saturated aqueous solution of calcium chloride as the mother liquor, and spray it into Spray granulation is carried out from inside the fluidized bed to the surface of silica. During the spray granulation process, the inlet air temperature is 62°C, the outlet air temperature is 55°C, the atomization pressure is 0.2Mpa, and the speed of the peristaltic pump is 200r / min. Obtain first-level coated particles;

[0030] (2) Add 100g hydrogenated castor oil and 100g calcium palmitate (the mass fraction of palmitic acid is 43%) into the mixer, heat and melt at 80°C, then add the first-level coated particles, and mix for 10min; put the above mixture Put into a 75kW granulator with...

Embodiment 2

[0033] A kind of coated calcium chloride, the concrete steps of its preparation method are as follows:

[0034] (1) Dissolve 750g of calcium chloride in water to prepare a saturated aqueous solution of calcium chloride, take 100g of silicon dioxide and put it into a granulation fluidized bed, atomize it with saturated aqueous solution of calcium chloride as the mother liquor, and spray it into Spray granulation is carried out from inside the fluidized bed to the surface of silica. During the spray granulation process, the inlet air temperature is 65°C, the outlet air temperature is 53°C, the atomization pressure is 0.2Mpa, and the peristaltic pump speed is 200r / min. Obtain first-level coated particles;

[0035] (2) Add 50g of hydrogenated castor oil and 50g of calcium palmitate (the mass fraction of palmitic acid is 45%) into the mixer, heat and melt at 80°C, then add the first-level coated particles, and mix for 12min; put the above mixture Enter 75kW aperture and be in the ...

Embodiment 3～6 and comparative example 1～3

[0038] The coating calcium chloride preparation method of embodiment 3~6 and comparative example 1~3 is except that the parameter listed in table 1 is different with embodiment 1, all the other contents are identical with embodiment 1.

[0039] Adopt the same preparation method as Example 1, only some parameters in the preparation method are different; Comparative Example 1 and Comparative Example 2 are also basically the same as the preparation method of Example 1, only the raw material composition ratio of coated calcium chloride Different, Comparative Example 3 uses different raw material compositions, specifically as shown in Table 1, and the parts not mentioned in Table 1 are the same as in Example 1.

[0040] The coated calcium chloride obtained carries out the mensuration of dissolution rate, and detection method is:

[0041](1) Adjust the temperature of the dissolution tester to 37°C and the rotational speed to 100r / min, pour the artificially prepared simulated rumen f...

Abstract

The invention discloses a coated calcium chloride and a preparation method thereof. The coated calcium chloride comprises the following raw materials in parts by weight: 5-20 parts of hydrogenated palm oil; 5-20 parts of hydrogenated castor oil; silicon dioxide 4 to 30 parts; 1 to 20 parts of fatty acid calcium; 60 to 85 parts of calcium chloride. In the present invention, hydrogenated palm oil, hydrogenated castor oil, silicon dioxide and fatty acid calcium are used as packaging materials, calcium chloride is used as a core material, and coated calcium chloride that can be used as a feed additive is obtained through multiple granulation and coating techniques. The coated calcium chloride not only makes up for the moisture-absorbing defect of the calcium chloride raw material, but also ensures that the calcium chloride passes through the rumen safely and reaches the intestinal tract smoothly, greatly improving the bioavailability of the calcium chloride.

Description

technical field [0001] The invention relates to the technical field of feed additives, in particular to coated calcium chloride and a preparation method thereof. Background technique [0002] Calcium chloride is an inorganic compound, a salt composed of chlorine and calcium elements, and is a typical ionic halide. The molecular formula of calcium chloride is CaCl 2 , the relative molecular weight is 110.98, and the properties are white, hard fragments or granules, slightly bitter, and odorless. Calcium chloride has strong hygroscopicity and is easily deliquified when exposed to the air. It is easily soluble in water and emits a lot of heat at the same time. Its aqueous solution is slightly alkaline. [0003] Calcium chloride is often used as an anion salt additive in dairy cow diets. It has the functions of supplementing the anions required by dairy cows, reducing the DCAD (dietary ion balance) value of dairy cows, improving the acid-base balance of dairy cows’ body fluids...
