Problems solved by technology

Feeds with high content of ferric iron are easy to form peculiar smells such as oil and haze, and the taste is poor. Feeding animals with such feeds will reduce the immunity of the animals and cause poor health, which will affect the feeding efficiency and the meat quality of the animals.
The above reactions are more obvious in high temperature and high humidity seasons, and the resulting consequences hinder the development of the feed industry

Embodiment 1

[0018] Feed grade ferrous sulfate monohydrate is joined in the biaxial paddle high-efficiency mixer, add No. 1 coating agent silicon dioxide that accounts for feed grade ferrous sulfate monohydrate weight 2% under stirring state, mix 5 minutes, make Silicon dioxide is fully covered on the surface of feed grade ferrous sulfate monohydrate and is coated for the first time; Then add No. 2 coating agent starch that accounts for 2% of feed grade ferrous sulfate monohydrate weight, mix 5 minutes again, make The starch is fully covered on the surface of the feed grade ferrous sulfate monohydrate covered with silicon dioxide for secondary coating to obtain the required coated ferrous sulfate.

Embodiment 2

[0020] Feed grade ferrous sulfate monohydrate is joined in the twin-shaft blade high-efficiency mixer, and under stirring state, add No. 1 coating agent sodium carboxymethyl cellulose that accounts for 2% of feed grade ferrous sulfate monohydrate weight, mix 5 Minutes, sodium carboxymethylcellulose is fully covered on the surface of feed grade ferrous sulfate monohydrate and is coated for the first time; Then add No. 2 coating agent starch that accounts for 2% of feed grade ferrous sulfate monohydrate weight, Mix again for 5 minutes, so that the starch is fully covered on the surface of the feed grade ferrous sulfate monohydrate covered with sodium carboxymethyl cellulose for secondary coating, and finally the desired coated ferrous sulfate is obtained.

Embodiment 3

[0022] Feed grade ferrous sulfate monohydrate is joined in the biaxial paddle high-efficiency mixer, add No. 1 coating agent silicon dioxide that accounts for feed grade ferrous sulfate monohydrate weight 5% under stirring state, mix 5 minutes, make Silicon dioxide is fully covered on the surface of feed grade ferrous sulfate monohydrate and is coated for the first time; Then add No. 2 coating agent zeolite powder that accounts for 5% of feed grade ferrous sulfate monohydrate weight, mix 5 minutes again, The zeolite powder is fully covered on the surface of the feed grade ferrous sulfate monohydrate covered with silicon dioxide for secondary coating, and finally the required coated ferrous sulfate is obtained.

Abstract

The invention discloses a method for coating feed-grade ferrous sulfate monohydrate, which comprises the following manufacturing steps: placing the feed-grade ferrous sulfate monohydrate into a double-shaft paddle mixer, adding NO.1 coating agent into the mixer first, and mixing the mixture for 5 to 6 minutes; and then adding NO.2 coating agent into the mixer, and mixing the mixture for 5 to 6 minutes to make the NO.2 coating agent fully covered on the surface of the ferrous sulfate monohydrate coated with the NO.1 coating agent so as to carry out secondary coating. The method has the following advantages that: the stability is remarkably improved, the color is not easily changed and unsusceptible to aggregation; when the coated feed-grade ferrous sulfate monohydrate is used for producinga trace element premix, a hydrophobic separation coating agent is used during stirring to establish a double-layer barrier and avoid oxidation-reduction reaction of components using water as a medium, so the product quality is stable, the color basically keeps unchangeable, the damage function on vitamin A and vitamin C in the composite premix is reduced, and the remaining rate of the vitamin A and the vitamin C is improved; and moreover, the production process is simple, the equipment investment is little, and the process is stable and controllable.

Description

technical field [0001] The invention relates to the field of feed additives, in particular to a method for coating feed grade ferrous sulfate monohydrate to improve stability by coating with a coating agent. Background technique [0002] Feed-grade ferrous sulfate monohydrate is the iron-containing element additive with the largest amount added in feed at present. It is almost all made of ferrous sulfate heptahydrate after cooking, centrifuging to remove crystal water, and then drying by air flow. The feed grade ferrous sulfate monohydrate produced by this method has stronger acidity (the pH of 10% aqueous solution is 2.6), relatively stable in the storage process, and after storing for one year, the content of ferrous iron does not change much (the actual measurement changes from 30.08% to 29.96%), that is to say Fe in ferrous sulfate 2+ Only a small amount is oxidized to Fe 3+ . However, when we use this feed-grade ferrous sulfate monohydrate to produce trace element pr...
