Calcium Hydrogen Phosphate Powder Usage and Synthesis.

Calcium Hydrogen Phosphate is a common food additive and its main uses include:

1) As a fortifier and bulking agent, used in cookies, infant formulas, and so on;

2) As a food and feed additive, used in livestock feed to supplement phosphorus and calcium elements;

3) Used as a calcium source in the food industry. In addition, calcium phosphate also has the role of anti-allergy, improve cell membrane permeability, increase the denseness of capillary wall.

The dosage and administration of calcium hydrogen phosphate is orally, 0.6-1.8g each time, 3 times a day. Note that Calcium phosphate may cause constipation. In terms of calcium supplementation, calcium phosphate is one of the common calcium supplements, but it should be noted that the best time to take calcium supplements should be before going to bed and between meals.

Uses of Calcium Hydrogen Phosphate.

Calcium Hydrogen Phosphate can be used as buffer; loosening agent; noodle improver nutritional supplement, yeast food, emulsifier, curing agent, antioxidant synergist, stabilizer. Such as for cherry filling core material canned, milk powder, cream powder, cold drinks, ice cream, potato, snack foods, flour, cakes, pastries, baking quality improver.

As a fortifier (supplemental calcium) and bulking agent, China's regulations can be used for cookies, infant formula, the maximum use of 1.0g/kg; can also be used as a quality improver for fermented pasta products, according to the production needs of the appropriate amount of use.

Used as auxiliary feed for poultry, it can promote the digestion of feed, and at the same time, it can also be used to treat rickets, cartilage, anemia and other diseases of livestock.

As food and feed additives to supplement the phosphorus and calcium elements in livestock feed.

Pharmacological effect of Calcium Hydrogen Phosphate.

Product Method of Bulk Calcium Hydrogen Phosphate Powder.

(1) Water extraction of ordinary calcium superphosphate method. It is obtained from agricultural common calcium superphosphate as raw material by multi-stage water extraction, defluorination and neutralization with lime milk. Water (solid-liquid ratio of 1.0-4.1) will be soluble phosphorus pentoxide in calcium superphosphate extracted from the solid phase by multi-stage extraction.

Sodium chloride or activated silica is added at the same time as the extraction for defluorination purification. The phosphogypsum slag was then removed by plate and frame press filtration. The filtrate is neutralized with lime milk containing 6%-8% CaO, and the neutralized solution is filtered and dried to a finished product after standing.

(2) Sulfuric acid extraction of phosphoric acid direct neutralization method. Phosphoric acid extracted from sulfuric acid after metering into the defluoridation tank, add defluoridating agent to remove fluorine, arsenic, lead and so on. After defluoridation of phosphoric acid into a neutralization tank, with lime milk neutralization, filtration slag as a by-product of fertilizer calcium phosphate, filtrate into the second section of the neutralization tank, with lime milk to continue to neutralize, filtration of filtrate back to the preparation of milk of lime, the filter cake by the air drying, crushed to become a product.

Phosphoric acid can also be obtained by direct neutralization with limestone: the calcined limestone into 70% -80% of the phosphoric acid, at 40-50 ℃ under the mixing and stirring reaction to generate a mixture of calcium hydrogen phosphate and calcium dihydrogen phosphate. After curing, it is chopped with a cutter and stacked in a maturation store to mature for 48h.

During this time, the remaining calcium carbonate reacts with dicalcium phosphate to form calcium hydrogen phosphate. The ripened material contains 15%-20% water and is baked in a rotary kiln until it contains less than 3% water, then crushed to obtain the finished product.
