Process for producing ferrous fumarate

Abstract

The invention discloses a process for producing ferrous fumarate. The process flow of the process comprises the following steps of: adding water in a salt dissolving kettle, and heating the water to atemperature of between 80 and 85 DEG C; adding fumaric acid and sodium carbonate in sequence; heating the mixture obtained by the previous step to a temperature of 100 DEG C; adding the mixture obtained by the previous step and ferrous sulphate in a reaction kettle; heating the mixture obtained by the previous step to the temperature of 100 DEG C for chemical reaction; discharging the resulting product and cooling resulting product; centrifugally separating the resulting product; drying the product of the centrifugal separation; measuring and packaging the product; and obtaining finished products. Due to the process, the production is free from 'three wastes' discharge, so that the environment is protected; the ferrous fumarate content of the product manufactured by the process is as highas 91.5 percent, the iron content of the product is 30 percent, the ferrous fumarate manufactured by the process can be widely used in animal feed additives in breeding production, is high in purity,iron content and absorption rate and low in cost and high in benefit, and can contributes to the sound and fast development of the state breeding industry.

Description

technical field [0001] The invention relates to a production process of ferrous fumarate, in particular to a production process of high-purity ferrous fumarate used as a feed additive, and belongs to the production field of ferrous fumarate. Background technique [0002] Iron is an essential trace element for animals. As a constituent and cofactor of enzymes, iron affects various metabolic activities of the body. It has been proved that trace elements play a role in the animal body in the form of organic matter or chelate, rather than in the state of ions. However, the trace element additives traditionally used to feed animals are almost exclusively inorganic salts. The metal ions released by inorganic salts during digestion are easily combined with other substances in the intestinal tract (such as phytic acid, oxalic acid, phosphate ions) to form insoluble salts and excreted, thereby reducing the absorption of trace elements and causing damage to the environment .

Problems solved by technology

[0004] However, the organic iron currently on the market, such as iron glycinate, iron lysine, iron methionine, etc., is very expensive, coupled with the lack of mature qualitative and quantitative analysis and testing methods, it is difficult to apply in actual production
