Description
Technical field
The present invention relates to feed addictive, especially relate to a kind of fodder acidulant that adopts fatty coating.
Background technology
At feed industry, antibiotic is a kind of conventional medicine, and it can effectively prevent the infection of animal intestinal pathogen, promotes animal health growth.But antibiotic abuse has become the important hidden danger that affects food security, even replace antibiotic use so reduce, for the quality that improves meat products, ensure that consumer's health is significant.Studies show that, the pH value in animal intestinal is significant to suppressing pathogen, therefore, in feedstuff industry, has become conventional method by the pH value that acidulant changes in animal intestinal.Conventional acidulant has small molecular organic acid or its salt such as citric acid, malic acid, lactic acid, calcium lactate, fumaric acid, potassium diformate, calcium formate, sodium butyrate or calcium butyrate at present, as potassium diformate or sodium butyrate, they enter in animal body with food, major part is decomposed, digests and assimilates in gastric juice, only has small part can enter the interior acidifying enteron aisle that plays a part of enteron aisle.So, in order to reach the object of acidifying enteron aisle, in feed, often to add than the acidulant of many several times of actual requirement, this has just increased feeding cost undoubtedly.For addressing this problem, the industry has adopted the method for coated slowly-releasing, by acidulant particle expoeridium release membranes, suppresses the decomposition of acidulant in gastric juice and digests and assimilates.As Chinese invention patent application (application number: 201210092693.2) just recorded a kind of method of preparing sodium butyrate enteric sustained release, its concrete steps are: (1) by dissolution of sodium hydroxide in water, at the uniform velocity drip n-butyric acie, dropwise and continue reaction 0.8 ~ 1.2 hour, obtain sodium butyrate reactant liquor; The mass ratio of NaOH and n-butyric acie is 7: 15 ~ 17; (2) in above-mentioned sodium butyrate reactant liquor, add auxiliary material, auxiliary material is one or both and one or more the mixture being selected from ethyl cellulose, hydroxypropyl cellulose, methacrylic acid, acrylate copolymer, propane diols, polypropylene glycol, mono stearate glyceryl ester, beta cyclodextrin in polyacrylic resin, acrylic resin; The amount of auxiliary material and the mass ratio of sodium butyrate are 125 ~ 500: 500.(3) by the material in (2), emulsification pretreatment 10 ~ 20 minutes, temperature control is 45 ~ 65 DEG C; (4) material after emulsification pretreatment in step (3) is imported in the centrifugal atomizer of spray tower, 5000～6000 revs/min of atomizing disk rotating speeds, temperature is 180～200 DEG C of spraying granulations; (5) cooling, concussion is sieved, and collects, and obtains sodium butyrate enteric sustained release.What above-mentioned coating was applied is spray drying process, and manufacturing cost is higher, and capsulating material costliness and consumption are large, and active principle content is low, and production cost is higher.
Summary of the invention
The object of the present invention is to provide a kind of fodder acidulant that adopts fatty coating, this acidulant production cost is low, active principle content is high, and in feed formula, consumption is few and good to enteron aisle acidizing effect.
For achieving the above object, the present invention can take following technical proposals:
The fodder acidulant of the fatty coating of employing of the present invention, its preparation technology comprises the steps:
The first step, by under normal temperature and pressure, be solvent liquefied petroleum gas, normal butane, high-purity iso-butane, propane, dimethyl ether, HFA 134a or the sulfur hexafluoride of gaseous state through compressor boil down to fluid storage in storage tank;
Second step, by coating material hydrogenated vegetable oil or/and palm stearin or/and higher fatty acids polyol polyester be dissolved in aforesaid liquid solvent;
The 3rd step, evenly mixes the solution that is dissolved with coating material in pressure vessel with acidulant particulate material, makes coating material evenly be coated on acidulant particle surface;
The 4th step, the release solvent that reduces pressure while stirring, then collects coating acidulant.
In described coating material, also can add 1 ~ 20% glycerin monostearate or/and emulsifying agents such as polyglycerol fatty acid ester or/and stearic acid calcium lactates.
Described acidulant is citric acid, malic acid, lactic acid, calcium lactate, fumaric acid, potassium diformate, calcium formate, sodium butyrate or calcium butyrate.
The granularity of described finished product coating acidulant is 0.05 ~ 1mm.
In described second step, coating material mixes, dissolves with subcritical fluids in dissolution kettle, and when mixing, temperature is 0 ~ 55 DEG C, and pressure is 0.1 ~ 0.8MPa.
The invention has the advantages that and utilize subcritical fluids packaging technique to prepare the fat-soluble dressing of fodder acidulant, technique is simple; In finished product, the weight portion of acidulant can, up to 80%, have been saved coating material greatly, has reduced production cost.
Brief description of the drawings
Fig. 1 is the process chart of embodiment 1,2,3.
Detailed description of the invention
The fodder acidulant of the fatty coating of employing of the present invention, its preparation technology comprises the steps:
