Problems solved by technology

[0006] At present, amino acid chelated calcium is prepared by pure chemical method (i.e., amino acid and calcium hydroxide are mixed in a closed container in a certain ratio and reacted), and this method has the following disadvantages: 1. The preparation time is long and the yield is low. 2. The chelation rate is low and the reaction is incomplete; 3. The solubility is low (referring to soluble in water), which affects the absorption

Embodiment 1

[0019] Such as figure 1 As shown, first pour L-aspartic acid and calcium hydroxide into a double-helix cone mixer (1 cubic meter) with a weight ratio of 3.8:1 to mix, then add fully automatic 0.5TRO reverse osmosis, sterilized pure water The pure water processed by equipment 2 is fully stirred; then it passes through the 110-type colloid mill 3, the steady flow box 4, the homogenizer 5 and the filter 6 and enters the double-helix cone mixer (5 cubic meters) 7 and passes through the steady flow Chest 8, obtains the mixed liquor that average particle size is 20 microns, total concentration is 25% (percentage by weight); This mixed liquor enters high-pressure fluid nanomill 9, and the pressure of controlling this nanomill is 90MPA; The liquid L-asparagus that obtains Amino acid chelated calcium enters storage barrel 10; Gained liquid L-aspartic amino acid chelated calcium passes through stirring stocker 11, drier 13 (connected with burner 12 for hot air), accumulator 14, collecto...

Embodiment 2

[0021] First pour glutamic acid and calcium hydroxide into a double-helix conical mixer (1 cubic meter) 1 with a weight ratio of 2.8:1 and mix them, then add the pure water, fully stirred; then through the 110-type colloid mill 3, the steady flow box 4, the homogenizer 5 and the filter 6 into the double-helix cone mixer (5 cubic meters) 7 and through the steady flow box 8 to obtain an average Particle size is 30 microns, the mixed solution that total concentration is 30% (percentage by weight); This mixed solution enters high-pressure fluid nanomill 9, and the pressure of controlling this nanomill is 130MPA; The liquid glutamic acid chelated calcium that obtains enters storage material Bucket 10; Gained liquid chelated calcium glutamate passes through stirring stocker 11, drier 13 (connecting with the burner 12 that gives hot blast), accumulator 14, accumulator 15, accumulator 16 successively again, Enter packing machine 17, obtain white powdery calcium glutamic acid chelate. ...

Embodiment 3

[0023] First pour lysine and calcium hydroxide into a double-helix cone mixer (1 cubic meter) 1 with a weight ratio of 3.3:1 and mix them, then add the pure water, fully stirred; then through the 110-type colloid mill 3, the steady flow box 4, the homogenizer 5 and the filter 6 into the double-helix cone mixer (5 cubic meters) 7 and through the steady flow box 8 to obtain an average Particle size is 15 microns, and total concentration is the mixed liquor of 10% (percentage by weight); This mixed liquor enters high-pressure fluid nanomill 9, and the pressure of controlling this nanomill is 110MPA; The liquid lysine chelated calcium that obtains enters storage material Bucket 10; Gained liquid lysine chelated calcium passes through stirring stocker 11, drier 13 (connecting with the burner 12 that gives hot air), accumulator 14, accumulator 15, accumulator 16 successively again, Enter packing machine 17, obtain white powdery lysine chelated calcium.

Abstract

The process of preparing amino acid chelated calcium includes the first step of mixing amino acid of granularity below 30 micron and calcium hydroxide in the weight ratio of 2.8-3.8 and adding water while stirring to obtain mixed liquid with total concentration below 30 mol%; and the second step of spraying the mixed liquid into nanometer high pressure fluid mill of pressure 90-130 MPa to obtain amino acid chelated calcium liquid, which is dried to obtain white powder product. The method is suitable for continuous large-scale production, and has high product chelating rate, complete reaction and complete dissolution of product in water.

Description

technical field [0001] The present invention relates to a preparation method of calcium supplement preparation and its special equipment, in particular to a preparation method of amino acid chelated calcium and its special equipment. Background technique [0002] Calcium is one of the most important elements in the human body. The function of almost every system of the human body is related to calcium. The harm of calcium deficiency to the human body has become an eye-catching worldwide problem. Especially the impact on infants, the elderly, pregnant women and patients with certain diseases is more serious. It has become a consensus that scientific calcium supplementation is beneficial to health. Normal people's daily physiological demand for calcium is 300-500 mg, but according to Chinese eating habits, the daily intake of calcium from food is only 150-200 mg. [0003] According to incomplete statistics, there are more than 200 kinds of calcium supplement preparations in t...
