Abstract
The invention discloses a dihydropyridine clathrate compound, which is prepared from 10 to 40 parts of dihydropyridine and 60 to 90 parts of deeply hydrogenated oil and by the steps of placing the deeply hydrogenated oil in a container, heating to 90 DEG C to melt, adding dihydropyridine and uniformly mixing to obtain uniformly mixed dihydropyridine oil solution; and making the dihydropyridine oil solution into powder. The dihydropyridine clathrate compound has the advantages that: based on the characteristics of a melting point of 58+/-2 DEG C and water insolubility of the deeply hydrogenated oil, the heated and molten deeply hydrogenated oil is mixed with the dihydropyridine to form the dihydropyridine oil solution; and the solution is atomized and condensed in a cooling tower through a spray nozzle, and solid particles are formed in a cooling and condensing process. As the melting point of the deeply hydrogenated oil is 58+/-2 DEG C, the clathrate compound can keep a good commodity state and does not block and melt in storage and transport processes. The dihydropyridine clathrate compound is very practical in preparation, transport and application processes and provides a technical support for industrial production.
Description
Technical field
The present invention relates to animal feed additive, especially relate to a kind of solid grease inclusion compound of dihydropyridine.
Background technology
Dihydropyridine (chemical name: 2; 6-dimethyl-3; 5-diethyl-ester group-l, the 4-dihydropyridine) be a kind of feed addictive of Multifunction, have biological function widely; As the control health medicine of angiocardiopathy, effects such as treatment fatty liver, toxic hepatitis, anti-ageing, anti-precocity are arranged medically.Dihydropyridine has antioxidation, can suppress biomembranous oxidation in the body, improves the activity of 6-glucophosphatase in the biomembrane, the stabilizing tissue cell, thus have some function of natural VE.Dihydropyridine can reduce the oxidational losses of nutriment such as VA, carrotene in the feed, improves the utilization rate of these materials, also can prevent the oxidative rancidity of grease, prolongs the storage period of grease.In feed, add the reproductive performance of digesting and assimilating, improve product quality, raising livestock and poultry, the raising domestic animal output of milk, raising poultry egg production that dihydropyridine can be regulated the livestock and poultry endocrine, promote mineral matter; The dihydropyridine body abroad has been widely used in producing as a kind of green feed additive, and 1996 is new veterinary additive by China's approval.Lot of test result shows; Dihydropyridine have stronger stabilization to VA, VE and carrot; Can improve be impregnated (essence) rate, incubation rate, laying rate, semen quality, the output of milk, daily gain and the price of deed of livestock and poultry; And the reduction feeding cost, be that a kind of consumption is few, the Mobyneb feed addictive of high efficiency, application prospect is very wide.
Yet dihydropyridine is done very easily oxidation and losing efficacy of time spent receiving heat, light, metal ion, and this causes difficulty just for the application of dihydropyridine in feed.In order to overcome this problem, Chinese patent CN101548714A has proposed the method with calcium alginate inclusion dihydropyridine, and this method is dihydropyridine and sodium alginate to be mixed to place water preparation concentration be the suspension of 0.5-2.0%; In solution, splash into calcium chloride and form gel, the shortcoming of this method is that suspension concentration is lower, and production efficiency is low; Because dihydropyridine is water insoluble; Dihydropyridine is difficult for disperseing in product, and the microballoon granularity of this method preparation is 2-4mm, and granularity is bigger.Since the addition of dihydropyridine in feed little (100g-500g/ ton), thus lack of homogeneity in feeding, caused, influence feeding effect.Also the someone utilizes cyclodextrin in the aqueous solution, to prepare the inclusion compound of dihydropyridine, but dihydropyridine and cyclodextrin (β-CD) solubility is very little in water, and its preparation method does not possess commercial value.
Summary of the invention
The object of the present invention is to provide a kind of dihydropyridine clathrate compound that can delay the dihydropyridine oxidational losses.
For realizing above-mentioned purpose, the present invention can take following technical proposals:
Dihydropyridine clathrate compound of the present invention is prepared from according to following weight parts proportioning and step raw material dihydropyridine, deep hydrogenation oil:
A, proportioning:
Dihydropyridine: 10 parts-40 parts,
60 parts-90 parts of deep hydrogenation oil;
B, preparation method:
The first step, place in the container heating to dissolve for 90 ℃ said deep hydrogenation oil, add said dihydropyridine then, stir the dihydropyridine oil solution that obtains mixing;
Second step, the dihydropyridine oil solution of the first step is carried out powder process get final product.
The said second step milling method is:
Through high-pressure pump the dihydropyridine oil solution is pumped in the tower from the nozzle that sprays top of tower, the nozzle diameter of said nozzle is 1 millimeter-4 millimeters; In spray, spray the downward transporting cold wind of top of tower certainly, the cold wind temperature is lower than 15 ℃; Collect the powder of spray column bottom gained, sieving gets final product.
It is 58 ± 2 ℃, water-fast characteristic that advantage of the present invention just is to utilize deep hydrogenation oil fusing point.Through choosing the proportioning of science, the deep hydrogenation oil after heating is dissolved is mixed and made into the dihydropyridine oil solution with dihydropyridine; Again with this solution through nozzle in the cooling tower condensation that atomizes, the dihydropyridine oil solution of atomizing forms the solid particle of dihydropyridine and the oily inclusion of deep hydrogenation in the cooling condensation process.Because atomizing cooling granulation adjustability on technology is strong,, utilize this method can make the pressed powder of powdery and pearl through adjustment nozzle bore and introducing cold wind adjustable-speed joint product particle particle diameter.Deep hydrogenation oil fusing point is 58 ± 2 ℃, so inclusion compound can not lump and melt storing, can keeping condition of merchandise preferably in the transportation.Because this method preparation technology is simple, efficient is high, product stability good, makes product of the present invention in preparation, transportation, application process, have very strong practicality, for suitability for industrialized production provides technical support.
