Embodiment 1
[0033] This embodiment provides a method for preparing biological amino acid feed from urban swill, comprising the following steps:
[0034] (1) Swill water pretreatment: sterilize urban swill at 100°C for 25 minutes and cool it for later use;
[0035] (2) On-line pre-grinding: add the pretreated swill into the pre-grinder and grind until the solid residual fineness is controlled to 100 mesh, the speed of the grinder is controlled at 300r / min, and the crushing time is controlled at 2min to obtain the urban swill base material ;
[0036] (3) Premix: the city swill base material and corn flour, soybean meal, rice flour, and sorghum flour are filled with fillers according to the mass ratio of 20:16:15:13:7, which is less than 100%. The filler is dried potato powder (including Water content 3%), carry out proportioning and carry out stirring and mixing, mixing time is 10min, obtains premix;
[0037] (4) Expansion preparation: add 3% bacillus and 7% biochemical protease to step (...
Embodiment 2
[0042] This embodiment provides a method for preparing biological amino acid feed from urban swill, comprising the following steps:
[0043] (1) Swill pretreatment: City swill was sterilized at 110°C for 27 minutes and cooled for later use.
[0044] (2) On-line pre-grinding: Add the pretreated swill to the pre-grinder and grind until the solid residual fineness is controlled to 150 mesh, the speed of the grinder is controlled at 1000r / min, and the crushing time is controlled at 10min to obtain the urban swill base material ;
[0045] (3) Premix: Fill urban swill base material with corn flour, soybean meal, rice flour, and sorghum flour according to the mass ratio of 30:19:21:17:10, which is less than 100%, and filled with filler, which is wheat flour (moisture content 1%) and the combination of peanut meal (water content 5%), carry out proportioning and carry out stirring and mixing, and mixing time is 20min, obtains premix;
[0046] (4) Expansion preparation: Add 5% lactic ...
Embodiment 3
[0051] This embodiment provides a method for preparing biological amino acid feed from urban swill, comprising the following steps:
[0052] (1) Swill pretreatment: City swill was sterilized at 120°C for 30 minutes and cooled for later use.
[0053] (2) On-line pre-crushing: Add the pretreated swill to the pre-crusher for crushing until the solid residual fineness is controlled to 250 mesh, the speed of the grinder is controlled at 1500r / min, and the crushing time is controlled at 15min to obtain the urban swill base material ;
[0054] (3) Premix: Fill urban swill base material with corn flour, soybean meal, rice flour, and sorghum flour according to the mass ratio of 30:22:17:20:10, which is less than 100%, and filled with filler, which is wheat flour (moisture content 1%) and rice flour (water content 4%), carry out proportioning and carry out stirring and mixing, and mixing time is 25min, obtains premix;
[0055] (4) Expansion preparation: add 8% Bacillus subtilis accord...
