Description
Technical field
The present invention relates to field of veterinary, particularly the method for preparing of salinomycin particle premix.
Background technology
Salinomycin is a monocarboxylic acid polyethers animal specific antibiotic; Most of gram positive bacterias and various coccidiosis there are stronger inhibition and killing action, are difficult for producing drug resistance and cross-resistance, drain rapidly; Residual quantity is extremely low, can be used for preventing and treating diarrhoea, growth promotion, raising survival rate.Salinomycin has the cation transport effect in cell, especially the affinity to potassium ion, sodium ion, rubidium ion is high especially, and these ion selectivities are flowed out outside films, causes ionic equilibrium to destroy, the osmotic pressure imbalance, cell expansion, be out of shape, break, disintegrate.
The method for preparing of Salinomycin pre-mixing agent comprises solvent extraction, spray drying method, plate-and-frame filtration method etc.Application number is that 93115177.5 Chinese patent discloses a kind of method of utilizing the Powdered feed grade Salinomycin Sodium of spray drying method for preparation; The Salinomycin fermentation liquid is heated through alkalization; After separating concentration, make excipient, adopt spray-dired method convection drying Salinomycin mycelium with calcium carbonate; Obtain the feed grade Salinomycin Sodium of different content, its finished product is the fawn uniform powder.This method is made Powdered Salinomycin Sodium, removes in the production process and very easily produces dust, influence the operative employee healthy outside, also progressively be eliminated along with the popularization of pellet.Application number is the method for preparing that 200410023920.1 Chinese patent discloses a kind of Salinomycin Sodium granule; Supernatant concentration is gone in Salinomycin fermentation liquid sedimentation after sterilization treatment; Add adjuvant and medicinal adhesive a-starch, methylol fiber sodium and sodium carboxymethyl cellulose in proportion; The adjustment pH value is an alkalescence, processes the dried granule of Salinomycin Sodium with the bed spray seasoning.Though this method can prepare the graininess Salinomycin Sodium by meeting the market requirement, complex procedures, the production cycle is long, and is all unfavorable to production cost and product quality.In addition, the content of the Salinomycin pre-mixing agent that prior art is prepared is generally 10% or 12%, and high-load Salinomycin pre-mixing agent can not reach requirement usually.
Summary of the invention
In view of this, the object of the present invention is to provide a kind of method for preparing of salinomycin particle premix, this method can reduce the influence of external additive, fast, stable, energy-conservation uniformity height and the high Salinomycin pre-mixing agent of content produced.
For realizing above-mentioned purpose, technical scheme of the present invention is:
The method for preparing of salinomycin particle premix may further comprise the steps:
A prepares alkaline broth: will tire is that the Salinomycin fermentation liquid of 60000～100000u/ml is regulated pH to 6.5～10.0 with alkali, alkaline broth;
B prepares the Salinomycin feed liquid: in step a gained alkaline broth, add the calcium carbonate that is equivalent to alkaline broth quality 0～25%, get the Salinomycin feed liquid;
C spray drying: step b gained Salinomycin feed liquid is processed granule with spray drying method, promptly get salinomycin particle premix.
Further, further comprising the steps of between said step a and the step b: as step a gained alkaline broth to be heated to 40～42 ℃ of insulations 4 hours earlier, to add sodium silicate solution and with acid for adjusting pH to 7～8, again according to the said adding calcium carbonate of step b;
Further, the mass concentration of said sodium silicate solution is 0.5%, and the addition of said sodium silicate solution is equivalent to 1～6% of alkaline broth volume.
Beneficial effect of the present invention is: this method is high with the salinomycin particle premix homogeneity and the stability of quick, energy-conservation mode of production preparation, and its content can be up to 31%; It is low at high-load salinomycin particle fat content that the present invention prepares, and then guaranteed quality of stability.
