Embodiment
The invention provides a kind of method of microorganism quick-fermented feed, feedstuff is existed using microbial premix Fermented in feed fermentation mixer, or so 3 hours can complete the fermentation of feedstuff, produce fermented feed.
Feedstuff is fermented present invention uses microbial premix.Contain in the microbial premix of the present invention Bacillus subtilis, bacillus coagulans, saccharomycete.The present invention is not particularly limited to the source of mentioned microorganism, can be adopted With the purchase strain of in the market.When using two kinds of strains or being a variety of, the present invention is to above two or the mixing ratio of a variety of strains Example is without special limitation, and the bacillus subtilis mixed using arbitrary proportion, bacillus coagulans and saccharomycete are all in this hair Within bright protection domain.In order to ensure the activity of microorganism in microbial premix, in the microbial premix of the present invention, In addition to including bacillus subtilis, bacillus coagulans, saccharomycete, other auxiliary materials are also added.One is added in the present invention The skin of beancurd powder of certainty ratio, certain nutrition supply is provided for microorganism.Skin of beancurd powder addition is 10~20 parts by weight in the present invention, Preferably 11~18 parts by weight, more preferably 12~16 parts by weight.In the present invention, the auxiliary material also include diatomite 80~ 90 parts by weight, preferably 82~88 parts by weight, are further 83~87 parts by weight, are used as the addition carrier of microbial premix.
Mentioned microorganism premix can be prepared using the conventional preparation method in this area.The specific implementation of the present invention The microbial premix used in example is used to spray into the bacterium solution containing bacillus subtilis, bacillus coagulans, saccharomycete and pressed In the skin of beancurd powder and diatomaceous auxiliary material that are mixed according to ratio, carry out low temperature drying and obtain microbial premix.The temperature of low temperature drying Spend for 30~40 DEG C, preferably 32~37 DEG C, more preferably 33~35 DEG C;The time of low temperature drying is 40~60min, excellent Elect 42~55min, more preferably 45~50min as.It is bacillus subtilis, solidifying in the microbial premix prepared It is 1*10 to tie the total content of bacillus and saccharomycete in auxiliary material8~1*1010CFU/g, preferably 1*109~1* 1010CFU/g.Wherein, the weight ratio of the bacillus subtilis, bacillus coagulans and saccharomycete is 1:1~3:1, further For 1:2:1.
Specific manufacturing process is as follows:
Feedstuff is put into feed fermentation mixer first and is stirred, feedstuff is well mixed.The present invention There is no special restriction to feedstuff.In the specific embodiment of the invention, feedstuff is one in dregs of beans, rapeseed meal and cotton dregs Plant or several mixtures, but the present invention is not limited thereto, can also include other kinds of feed fermentation raw material.According to described It is different containing moisture in feedstuff, moderately adjust its moisture.Heretofore described feedstuff, which is adjusted to its moisture, to be contained Amount meets containing needed for microbial fermentation 50%~60%, preferably 53%~58%, more preferably 54%~56% Water.The present invention is not particularly limited to the mode for adjusting the feedstuff water content, can put into feed in feedstuff Its moisture is adjusted before fermentation mixer, water can also be added into feed fermentation mixer at the initial stage of mixing Point.It is preferred that adjusting the moisture of feedstuff before fermentation.
After the feedstuff stirs 2~3min in feed fermentation mixer, microbial premix is added described Continuously mixed in feed fermentation mixer.
In order to improve the fermentation efficiency that microorganism utilizes fermented material, shorten fermentation period, the present invention is in feed fermentation Required microorganism is screened, and bacillus subtilis, bacillus coagulans and saccharomycete is carried out into scientific matching, in fermentation Different phase, adds the premix of different proportion microorganism.In the microbial premix just added, the bacillus subtilis The weight ratio of bacterium, bacillus coagulans and saccharomycete is preferably 1:1~2:1, more preferably 1:1~1.5:1, further For 1:1:1.
In the present invention, the weight ratio of the mentioned microorganism premix of addition and the feedstuff is 7.5~10kg/t, Preferably 8~9.5kg/t, more preferably 8.0~8.5kg/t.
In the present invention, add after the microbial premix, the spinner velocity of the feed fermentation mixer is controlled 25 ~30 revs/min, so that the fermentation temperature in feed fermentation mixer is controlled in certain climbing speed, make microorganism in hair The oxygen needed for fermentation can be kept in the ferment time.The spinner velocity of preferably feed fermentation mixer of the invention for 26~29 turns/ Minute, it is further 27~28 revs/min.Now, fermentation mixer frequency converter frequency be 45~55HZ, preferably 48~ 52HZ, is further 50HZ.With the continuation of fermentation process, frictional heat makes feeding together with the metabolism heat that microbial fermentation is released The temperature of material rises in material fermentation mixer, until the temperature of charge in feed fermentation mixer is 40~50 DEG C.In this rank Duan Zhong, the time that feed fermentation mixer continuously stirs fermentation is 1.0~1.5 hours, preferably 1.1~1.3 hours.
When temperature of charge rises to certain temperature, microbial premix is added again in the feed fermentation mixer Continue to stir fermentation.In the present invention, the temperature of the material is 40 DEG C~50 DEG C when adding microbial premix again, preferably For 43 DEG C~48 DEG C, more preferably 44 DEG C~46 DEG C.The amount of the microbial premix added again, come by feedstuff based on Calculate, feedstuff addition 7.5~10kg of microbial premix, preferably 7.8~9.5kg, more preferably 8.0 per ton~ 8.5kg.The microbial premix this time added is two kinds or many in bacillus subtilis, bacillus coagulans and saccharomycete Kind, and need not strictly limit identical with the amount or ratio added first.If adding the progress of two or more microbial premixes Fermentation, it is preferred that the mixed proportion of the bacillus subtilis, bacillus coagulans and saccharomycete is 1:2~3:1, further Preferably 1:2.2~2.8:1, more preferably 1:2.5:1.
