Production method of composite phosphate

Abstract

The invention discloses a production method of composite phosphate. The production method includes: using monomer phosphate or physically-mixed phosphate as the raw material, controlling the temperature to be at 200-40 DEG C, adding a certain proportion of water under a stirring state, controlling the temperature of the phosphate in different ranges, and using the hydrolysis of the phosphate to produce the composite phosphate of different proportions and properties according to different water adding proportions and temperatures. The production method has the advantages that the dissolving speed of the produced composite phosphate can reach the dissolving speed of chemical mixing, caking of the produced composite phosphate in water is avoided, the high-concentration composite phosphate is fast in dispersing, and the normal-concentration composite phosphate is fast in dissolving; the phosphate production cost of factories is not increased evidently, and only the cooling equipment of an original phosphate production line needs to be slightly modified.

Description

technical field [0001] The invention relates to a production method of composite phosphate. Background technique [0002] At present, compound phosphate has an irreplaceable role in many fields such as food and mechanical processing, but the effect of monomeric phosphate is very limited, and its use is subject to many restrictions. The main reason is that it is difficult to meet the requirements of dissolution rate and effect at the same time. Composite phosphate can be produced through physical mixing, but because the particle size and properties of each monomer are different, it is easy to agglomerate when dissolved, and the dissolution speed is slow, which seriously affects food safety and production efficiency. [0003] Although there are some factories in the world that have already produced instant composite phosphate, the production of composite phosphate by controlling the degree of neutralization and polymerization temperature in the polymerization stage requires ve...

[0002] At present, compound phosphate plays an irreplaceable role in many fields such as food and mechanical processing, but the role of monomeric phosphate is very limited, and its use is subject to many restrictions, mainly because the dissolution rate and effect are difficult to meet the requirements at the same time

Composite phosphate can be produced by physical mixing, but because the particle size and properties of each monomer are different, it is easy to agglomerate when dissolved, and the dissolution speed is slow, which seriously affects food safety and production efficiency

[0003] Although there are some factories in the world that have already produced instant composite phosphate, the production of composite phosphate by controlling the degree of neutralization and polymerization temperature in the polymerization stage requires very high equipment and process control, and the product price is high.
