and then, according to the addition proportion of 0.1 percent of vitamin premix in the feed, weighing the water-in-oil type vitamin premix, mixing and diluting the water-in-oil type vitamin premix with soybean oil, and carrying out post-spraying on the feed.

The technical field is as follows:

the invention relates to a vitamin premix, in particular to a preparation method of a water-in-oil type liquid vitamin premix and application thereof in post-spraying of feed.

Background art:

vitamins are trace organic matters necessary for the growth and metabolism of animals, but generally cannot be produced by organisms themselves and need to be obtained by means of diet and the like. Animals cannot grow normally when lacking vitamins and develop specific lesions, namely, vitamin deficiency.

In the feed processing process of the feed industry in China, vitamins are added in the form of a vitamin mixture, and the vitamin mixture is generally called vitamin premix. Vitamin premixes are incorporated into animal feed in two forms, the most widely used method being the incorporation of vitamins in powder form into the feed ingredients, followed by pelleting. The method has the problem that the factors such as mechanical friction, high temperature, high pressure and high humidity in the granulating process can cause great loss of vitamins. In another mode, the liquid vitamin premix is quantitatively sprayed on the feed particles by using spraying equipment after the feed is granulated, so that the heat sensitivity loss is avoided. Compared with solid vitamins, the retention rate of the vitamins sprayed to the granulated feed by using the post-spraying technology can be improved by 15-60 percent.

At present, the liquid vitamin complex premix has some technical problems in the post-addition process, for example, after a plurality of vitamins are mixed in a liquid state, a plurality of vitamins are more active than those in a solid state form and are easy to react with each other or cause the degradation of the vitamins, so that an effective method for preparing the vitamin premix is needed to be found, the stability of the liquid vitamins is improved, and the quality loss of the liquid vitamins is reduced as much as possible. In addition, the liquid vitamin premix used in the prior production and the patent is oil-in-water concentrated solution, and can be sprayed after being diluted by water, so that the water content of feed particles is increased, and the feed mildew is easily caused. If vitamins are prepared into water-in-oil type emulsion, the emulsion can be added after thermosensitive trace components, and the emulsion is diluted by the oil and then is sprayed synchronously with the oil.

The invention content is as follows:

the invention aims to provide a preparation method and application of a water-in-oil type liquid vitamin premix. The invention has the advantages and positive effects that: (1) the liquid vitamin premix can avoid the reaction or degradation among vitamins through reasonable compatibility, and remarkably improves the stability of the vitamins during the storage period, thereby improving the utilization rate of the vitamins; (2) the liquid vitamin premix does not need high-pressure homogenization treatment in the production and application process, and can form a water-in-oil type liquid vitamin concentrated solution through spontaneous emulsification in a low-energy emulsification method, so that the energy consumption is greatly reduced; (3) the water-in-oil type liquid vitamin concentrated solution is diluted by grease and then is sprayed on the feed, so that the increase of the feed moisture caused by the dilution of water in the post-spraying process of the oil-in-water type liquid vitamin premix can be avoided, and the risk of feed mildew is reduced.

The purpose of the invention is realized by the following technical scheme:

Further, the group C liquid vitamin formulation consists of vitamin K3. K3 is added in the form of Menadione Sodium Bisulfite (MSB), the concentration of vitamin K3 is 8-12g/kg, the solvent of the liquid vitamin ingredient in group C is water, and the stabilizer of the liquid vitamin ingredient in group C is at least one of sodium chloride, sorbitol, 1, 2-propylene glycol and glycerol.

The preparation method of the water-in-oil type liquid vitamin premix comprises the following steps:

step 1, in a liquid preparation tank, adding vitamin B12 into a solvent under a stirring state to ensure uniform mixing, sequentially adding an antioxidant and vitamin E, A, D in the process of continuing stirring, and finally adding a compound emulsifier into the uniform liquid to prepare a liquid vitamin ingredient in group A;

step 2, preparing a stabilizing agent, an antioxidant and a suspending agent into an aqueous solution in a liquid preparation tank under the condition of stirring, then sequentially adding biotin, vitamin B6, B5, B3, B1 and B2 into the aqueous solution, and continuously stirring the mixed solution for 20min to prepare a B group liquid vitamin ingredient;

and 3, stirring and mixing the water and the stabilizer in the batching tank to obtain an aqueous solution. Then adding vitamin K3 to make into liquid vitamin C ingredient.

The liquid vitamin premix has the advantages that three independent liquid vitamin ingredients are stable in a liquid state, and the three liquid vitamin ingredients are mixed when in use, so that the three ingredients can be sold in a product form after being packaged and combined, and choline chloride and vitamin C have destructive effects on other vitamins and need to be separately prepared and added, so that the liquid vitamin premix does not contain choline chloride and vitamin C, and in a word, the problem of vitamin stability of the conventional vitamin premix is solved to a certain extent.

The application method of the water-in-oil type liquid vitamin premix comprises the following steps: in a high-speed shearing tank, firstly mixing the liquid vitamin ingredient of the group A and soybean oil in a volume ratio of 1: 9, then slowly adding the liquid vitamin ingredient of the group B and the liquid vitamin ingredient of the group C into the liquid vitamin ingredient of the group A in a trickle mode for mixing and emulsifying to form a water-in-oil type liquid vitamin premix, then measuring the water-in-oil type vitamin premix according to an addition ratio of 0.1 percent of the vitamin premix in the feed, mixing and diluting the water-in-oil type vitamin premix and the soybean oil, and immediately spraying the feed.

The method adopted when the water-in-oil type liquid vitamin premix is applied is a spontaneous emulsification method in a low-energy emulsification method, and the water-in-oil type emulsion is prepared by using chemical energy stored in the system through the change of the spontaneous curvature of the surfactant instead of an external mechanical device. One of the keys to this process is that each water-soluble vitamin droplet is surrounded by a continuous oil phase to form a water-in-oil (W/O) emulsion.

The water-in-oil type liquid vitamin premix is diluted by grease and then synchronously sprayed with vitamin and grease on the feed, so that the process of spraying multiple heat-sensitive components (vitamin, enzyme preparation, grease and the like) for many times is reduced, the feed moisture caused by dilution with water in the process of spraying the oil-in-water type liquid vitamin premix can be avoided, and the risk of feed mildew is reduced
