The invention provides a method for producing biologic
protein feed by using
solid-state
fermentation fiber dreg. The method comprises the steps: activating, inoculating, cultivating and fermenting
lignin trichodermin strain, candida utilis and
saccharomyces cerevisiae to obtain a first liquid strain and a second liquid strain; adding maize flour,
ammonium sulfate and
potassium dihydrogen
phosphate in maize soaking water, regulating pH value, conducting
steam sterilization to obtain liquid
nutrient solution; evenly agitating the dried wet maize peel dreg with
bran, maize steep liquor, bean pulp, rice
chaff and
urea together, regulating pH value to obtain starting crude base stock; evenly mixing the liquid
nutrient solution and the starting crude base stock, then inoculating, fermenting, continuously agitating and supplying
fresh air, simultaneously adding inorganic salt, and evenly mixing; and
drying the fermented materials at the temperature lower than 55 DEG C to obtain the biologicprotein feed. According to the method, the biologic
protein feed is produced by utilizing wet maize peel dreg generated in process of producing
starch from maize through wet method, and maize soakingwater, so that the additional value is increased, and the cost is lowered.
