Description
Technical field
The present invention relates to the packaging technique field in Feed Manufacturing, especially relate to a kind of coating preparation method of fodder acidulant.
Background technology
Acidulant is a kind of conventional feed addictive, feed acidity can be improved, utilize acidulant can reduce the pH value of animal gastrointestinal tract, thus improve the mechanism of the digestion activity of animal gastrointestinal tract, appropriate acidulant is added in animal and fowl fodder, multiple digestive zymogen can be activated active, promote nutrient digestion to absorb and prevention diarrhea; Reduce the impact that heat stress causes; Reduce the risk that pathogenic bacteria are propagated as Escherichia coli and salmonella.
Wherein, the small molecular organic acids such as formic acid, acetic acid and propionic acid not only can reduce pH value, also have inhibitory action to Gram-negative bacteria; The macromolecule organic acid such as fumaric acid, lactic acid can reduce intestines and stomach pH value, reaches the effect indirectly reducing harmful levels of pathogens.In prior art, produce fodder acidulant equipment, mixed type technique is adopted simply to adsorb realization, the active ingredient of the product produced fails to be effectively protected, product in use, there will be problems, such as: the active ingredients such as volatile formic acid, processing, deposit with use procedure in easily lose, the stability of product quality can not get effective guarantee; The active ingredient such as acids without protection can produce with other the alkaline nutriment in feed reacts, and reduces that feed is mesotrophic tires, and the stability of feed product quality can not get effective guarantee; Part active ingredient belongs to middle strong acid, has stronger corrosivity, and the phosphoric acid without protection can partial injury animal oral cavity mucous membrane and the palatability affecting feed.Acidulant without effectively process enters in animal body and can be released immediately, thus affects animal self hydrochloric acid in gastric juice and pepsic secretion.Due to above problems, limit its application in feed.
In existing technology, in order to alleviate acidulant excitant strong, there is corrosivity, volatile instability, the easily moisture absorption, be difficult to avoid the impact etc. of feed neutral and alkali raw material, adopt and add packaging material bag quilt on acidulant surface.There are many different bags by scheme, as Chinese patent 2003101063387, the effect of this formulation to acidulant has some improvement, but it is incomplete also to there is coating in actual production, the defect that cost is also higher, the patent No. is a kind of composite protection type acidulant disclosed in CN201110068163.X, described composite protection type acidulant is encased whole for compound acidulant by coating material, thus make acidulant slow releasing in gastric environment, drop to minimum to the disturbance degree of animal self hydrochloric acid in gastric juice and propepsin secretion, but the acidulant of this patented invention can not play optimum effect in enteron aisle.
Summary of the invention
For the problems referred to above that prior art exists, the applicant provides a kind of coating preparation method of fodder acidulant granules.Preparation technology of the present invention is simple, and obtained granules stable performance, easily stores, long shelf-life, and protecting Be very effective in poultry alimentary canal health, can significantly improve the biologically active of poultry.
Technical scheme of the present invention is as follows:
A coating preparation method for fodder acidulant granules, concrete steps are as follows:
(1) shitosan 10 ~ 12 parts, citric acid 15 ~ 20 parts, malic acid 15 ~ 20 parts were mixed 300 mesh sieves, and added lactic acid 20 ~ 30 parts, polyethylene glycol 5 ~ 8 parts, mix rear mist projection granulating;
(2) granulation material that 1 ~ 2 part, formic acid, acetic acid 12 ~ 15 parts, propionic acid 3 ~ 5 parts, butyric acid 10 ~ 15 parts, hydroxypropyl methylcellulose 10 ~ 12 parts, aerosil 2 ~ 3 parts obtain with step (1) is mixed, adopt screw extruder to carry out granulation;
(3) fumaric acid 1 ~ 3 part, ethanol 5 ~ 10 parts, 1 ~ 3 part, benzoic acid, melt polypropylene acid resin 20 ~ 25 parts are uniformly mixed into coating liquid; The granulation material that step (2) obtains is placed in the fluid bed of fluidized coating machine, passes into air-flow and make it be suspended in the dressing room of fluidized coating machine; Dressing room will be sprayed into after coating liquid, thus wrap the granulation material that step (2) obtains; And pass into hot-air and carry out drying, the granulation material that coating liquid is obtained in step (2) is outer dry thus form dressing, namely obtains described fodder acidulant granules;
Step (1) ~ (3) described part is parts by weight.
The EAT of step (1) mist projection granulating 90 ~ 100 DEG C, leaving air temp 60 ~ 70 DEG C, granulation particle diameter is 100 ~ 150 microns.
The particle diameter of step (2) screw extruder granulation is 300 ~ 500 microns.
The consumption of coating liquid described in step (3) is 20 ~ 30 microns for making described coating thickness.
The technique effect that the present invention is useful is:
The object of the present invention is to provide a kind of spacetabs type compound acidulant and preparation method thereof, solve existing acidulant DeGrain, active principle content is not high, overcome the shortcoming of the common acids agent prepared by prior art, the novel formulation form of exploitation further can improve the effect of acidulant, plays multisection type release (controlled release) coating acidulant, more acid is allowed to enter small intestine, improve intestinal environment, except can regulating the pH value of stomach, the pH value of all right regulating intestinal canal.More effective pre-anti-diarrhea.In addition the coating acidulant particle spherical in shape produced of present invention process, free-running property is good, and total acid content improves, and does not affect other nutritions in feed, prevents from acidulant from contacting with other alkaline matters flatulence occurs reacting.There is no the generation of dust in process, improve production environment, reduce energy consumption, reduce artificial, and this technique also reduces the corrosiveness of common acids agent to process equipment yet.
