Problems solved by technology

[0004] So far, feed companies have realized the anti-mold and acidification functions by adding two separate products, the anti-fungal agent and the acidifying agent, and have not integrated the large amount of acidic functions of the anti-fungal agent into the scientific design. Acidification and acidulant combined with anti-mold effect will easily lead to the abuse or vacancy of certain acids in use, and also increase the probability of antagonistic effects

Embodiment 1

[0043] Embodiment one: the preparation method of composite antifungal agent solid powder, the steps are as follows:

[0044] (1) Preheat the liquid ammonia to 40-45°C with an ammonia preheater, control the pressure at 1-1.5MPa, and then disperse it through a disperser, and then evenly and slowly pass it into the reaction kettle with an appropriate amount of propionic acid, and use 60- Stir the reaction at a speed of 80r / min, and at the same time turn on the cooling water to cool down, so that the exothermic temperature in the kettle does not exceed 100-110°C, and the weight content of free propionic acid in the reaction kettle is reduced to 1% of the whole liquid by sampling and testing (conventional acid-base titration method). When it is about 80%, stop feeding ammonia gas, continue to stir for 2-3 minutes, and cool down to get the mixture of propionic acid-ammonium propionate-ammonium dipropionate;

[0045] (2) Preheat the liquid ammonia to 45-50°C with an ammonia preheater...

Embodiment 2

[0049] The preparation method of composite antifungal agent solid powder, the steps are as follows:

[0050] Steps (1), (2) and (4) are the same as Example 1, and the difference of step (3) is only to take 45 parts by weight of propionic acid-ammonium propionate-ammonium dipropionate mixture and 10 parts by weight of glacial acetic acid-acetic acid Ammonium-Ammonium Diacetate Mixture.

Embodiment 3

[0052] The preparation method of composite antifungal agent solid powder, the steps are as follows:

[0053] Steps (1) and (2) are the same as in Example 1, the difference of step (3) is only to take 40 parts by weight of propionic acid-ammonium propionate-ammonium dipropionate mixture and 5 parts by weight of glacial acetic acid-ammonium acetate-diacetic acid Ammonium mixture, the difference in step (4) is to weigh 24 parts by weight of activated silicon dioxide in the mixer, spray the mixed solution of (3) under stirring, after the absorption is completed, weigh 4 parts by weight of fine powder Benzoic acid, 1 weight part of sorbic acid and 26 weight parts of zeolite powder are added, stirred evenly, sieved, inspected and packaged to obtain a composite antifungal agent solid powder.

Abstract

The invention provides a compound mouldproof agent with the acidizing effect and a preparation method thereof. The compound mouldproof agent comprises the following components in parts by weight: 20-50 parts of propionic acid-ammonium propionate-ammonium dipropionate mixture, 5-15 parts of glacial acetic acid-ammonium acetate-ammonium diacetate mixture, 2-10 parts of benzoic acid, 1-3 parts of dehydroacetic acid and/or sorbic acid and 37-55 parts of vectors. The invention also provides the preparation method of the compound mouldproof agent, which is characterized by evenly stirring the mixture of the 20-50 parts of propionic acid-ammonium propionate-ammonium dipropionate mixture, the 5-15 parts of glacial acetic acid-ammonium acetate-ammonium diacetate intermediate product components, the 2-10 parts of benzoic acid, the 1-3 parts of dehydroacetic acid and/or sorbic acid and the 37-55 parts of vectors, filtering, inspecting and packaging, thus obtaining the compound mouldproof agent. The compound mouldproof agent has double functions of mould proofing and acidizing, is synergistic, avoids antagonism and is simple in preparation, low in cost and high in application value.

Description

technical field [0001] The invention relates to feed additives, in particular to a compound antifungal agent with acidifying effect and a preparation method thereof, belonging to the field of feed safety and preservation. Background technique [0002] There are contradictions between limited natural resources and more and more complicated diseases, poisoning and pollution, and the continuous improvement of people's living standards and requirements for continuous improvement, which prompts the feed industry to develop rapidly, expand its scale and require continuous improvement of feed quality. But the global climate is deteriorating day by day, such as severe drought, torrential rain, increasing temperature difference, rapid typhoon, etc., coupled with frequent and changeable influenza, have a catastrophic impact on the production, storage and transportation of feed: mildew. Moldy feed, that is, mold and spoilage bacteria breed, produce toxins, destroy nutrients, decompose ...
