Abstract
Production of ferrous fumarate is carried out by taking allomaleic acid, soda and iron vitriol as material, putting allomaleic acid and soda into enamel reactor, raising temperature to 80deg.C, agitating, raising temperature of iron vitriol, sodium hydrogen sulfite and water to 60-80deg.C, adding into enamel reactor with 60-80deg.C and pH 8.5-9.5, centrifugalizing reactant to water content 20%, drying, breaking, screening with 80 mesh. Its achieves high productivity and stabilizing process.
Description
Technical field
The present invention relates to a kind of production technique of fodder additives, specifically a kind of production technique of Ferrous Fumarate.
Technical background
In recent years, in field of fodder, the research of the physiological function of relevant iron comes into one's own day by day, and disease that iron deficiency caused and developmental defect also are subjected to people's attention.In order to improve iron undernutrition conditions in the swinery, it is necessary conscientiously that swinery is carried out generally, reasonably mends iron.Safety, efficient, the economy development and the production of practical iron enriched nutrient have again become the worker's of China Animal nutrition educational circles important topic.Studies show that, in general.The iron of divalence state more helps pig than the iron of trivalent state and absorbs, and organic iron is littler and be easy to absorb to the stomach pungency than inorganic iron, and heme iron is easy to absorb than nonheme iron etc.Ferrous Fumarate equally is the ferrous iron preparation with ferrous sulfate, and characteristics are the iron-holder height, and are more stable, and pungency is little and rapid-action.Medicine, healthcare products and animal feedstuff additive have been widely used as.But the production technique of existing Ferrous Fumarate is to be that raw material reaction generates Ferrous Fumarate with fumaric acid, soda ash and ferrous sulfate, and the content of the resultant Ferrous Fumarate 90-95% that is everlasting wherein also has the ferric iron ferrous fumarate of 5-10%.When it was used as the additive of animal-feed, not only addition increased, and the ferric iron that contains in the additive is influential.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of production technique that improves the Ferrous Fumarate of Ferrous Fumarate content.
The technical scheme that the present invention solves the problems of the technologies described above is: a kind of production technique of Ferrous Fumarate is to be that raw material generates Ferrous Fumarate with fumaric acid, soda ash and iron vitriol, it is characterized in that adding in generative process the sodium bisulfite reductive agent.
The concrete steps of production technique of the present invention are: fumaric acid and soda ash are put into enamel reaction still be warming up to 80 ℃ of stirrings, add enamel reaction still after then iron vitriol, sodium bisulfite and water being warming up to 60-80 ℃ together, the reactor controlled temperature is 8.5-9.5 at 60-80 ℃, pH value, then with reactant centrifugal to water content be 20%, dry again, pulverize, cross 80 mesh sieves.
The consumption of above-mentioned each raw material is respectively: fumaric acid 130-170kg, PH are the soda ash 150-180kg of 9-10, iron vitriol 400-450kg, sodium bisulfite 7-9kg, water 480-520L.
The present invention is owing to added sodium bisulfite as reductive agent in reaction; and often there is oxidative phenomena to produce in the art production process in order to overcome; cause the unsettled deficiency of quality; also can add nitrogen protection; therefore; stable processing technique, the productive rate height, the content of Ferrous Fumarate reaches more than 97%.
Embodiment
Embodiment 1:
With fumaric acid 130kg, PH is the soda ash 150kg of 9-10, iron vitriol 400kg, and sodium bisulfite 7kg, water 480L generates Ferrous Fumarate by following technological process operation.
Embodiment 2:
Fumaric acid 170kg, PH are the soda ash 180kg of 9-10, iron vitriol 450kg, and sodium bisulfite 9kg, water 480L generates Ferrous Fumarate by following technological process operation.
Embodiment 3:
Fumaric acid 15kg, soda ash 160kg, iron vitriol 420kg, sodium bisulfite 8kg, water 500L generates Ferrous Fumarate by following technological process operation:
Claims (2)
1, a kind of production technique of Ferrous Fumarate is to be that raw material generates Ferrous Fumarate with fumaric acid, soda ash and iron vitriol, it is characterized in that adding in generative process the sodium bisulfite reductive agent.
2, production technique as claimed in claim 1, the concrete steps that it is characterized in that its production technique are: fumaric acid and soda ash are put into enamel reaction still be warming up to 80 ℃ of stirrings, add enamel reaction still after then iron vitriol, sodium bisulfite and water being warming up to 60-80 ℃, the reactor controlled temperature is 8.5-9.5 at 60-80 ℃, pH value, then with reactant centrifugal to water content be 20%, vacuum-drying is again pulverized, and crosses 80 mesh sieves.
The consumption of above-mentioned each raw material is respectively: fumaric acid 130-170kg, content are 98.8% soda ash 150-180kg, ferrous sulfate 400-450kg, sodium bisulfite 7-9kg, water 480-520L.
