Embodiment 1

[0020] Take 210kg of raw materials glycine, 90kg of calcium oxide and 700kg of water, mix them in a reactor, stir to fully dissolve, react at a temperature of 30°C for 5 hours, take the reaction solution, and let it stand for 8 hours; spray dry at 280°C, detect water parts, so that the moisture weight percentage is less than 9%, to obtain 210kg of dry matter, take the dry matter, pulverize, pass through a 100-mesh sieve, sterilize, and pack.

Embodiment 2

[0022] Take 300kg of raw materials glycine, 100kg of calcium oxide and 60kg of water, mix them in a reactor, stir to fully dissolve, react at 70°C for 12 hours, and let stand for 10 hours; take the reaction solution, spray dry it at 200°C, and detect water parts, make the moisture content by weight less than 7%, to obtain 270kg of dry matter, take the dry matter, pulverize, pass through 80 mesh sieve, sterilize, and pack separately.

Embodiment 3

[0024] Take 150kg of raw materials glycine, 80kg of calcium carbonate and 770kg of water, mix them in a reactor, stir to fully dissolve, react at a temperature of 55°C for 18 hours, and let stand for 12 hours; take the reaction solution, spray dry it at 250°C, and detect water parts, make the moisture content by weight less than 8%, to obtain 142kg of dry matter, take the dry matter, pulverize, pass through a 120 mesh sieve, sterilize, and repack.

Abstract

The invention discloses a method for preparing calcium glycine, which comprises the following steps: respectively taking 15 to 30 weight percent of glycin, 0.8 to 15 weight percent of mineral calcium and 60 to 80 weight percent of water, mixing and stirring the raw materials in a reaction kettle to make the raw materials fully dissolved, performing reaction for 3 to 24 hours by heating at a temperature between 30 and 80 DEG C, and then standing for 6 to 24 hours; taking reaction solution, and performing spray drying or freeze drying to obtain a dry substance; and crushing the dry substance, passing through a 80 to 120-mesh sieve, performing sterilizing and split charging. The method for preparing the calcium glycine has easily obtained raw material used, scientific and reasonable mixture ratio of the raw materials, simple preparation process, high yield of the synthesized calcium glycine, low cost and suitability for industrial production.

Description

technical field [0001] The invention discloses a preparation method of a compound, and specifically discloses a preparation method of calcium glycinate. Background technique [0002] The calcium intake of people of different ages and occupations in my country is generally low. The average daily intake of calcium per person is only 400 mg, which is only about 50% of the calcium intake recommended by the Chinese Nutrition Society. The phenomenon of calcium deficiency in children and adolescents is even more serious. In severe cases, 70% to 80% of children and adolescents get less than 50% of the recommended calcium intake. At present, most of the human body calcium supplement products used in China are the first generation of active calcium and the second generation of ordinary organic calcium salt. Among them, the first generation of calcium supplement (active calcium) is actually calcium oxide or calcium carbonate. It is strongly alkaline (pH value > 12), consumes a large...
