With Lactobacillus rhamnosus immixture remove aspertoxin and etc. obtain can Direct-fed livestock and poultry corn pulp, spray drying system
Obtain Dried Corn Steep Liquor Powder.
Chinese patent 201610789852.2 discloses a kind of fermenting corn steep liquor feed and its production method, this method are main
It is to add mixed bacteria liquid, lactic acid bacteria, mannosan, saccharomycete to maize peel, wheat bran, corn flour, dregs of beans are added in corn pulp
Aerobic, the anaerobic fermentation for carrying out different phase, can effectively reduce the toxin index in corn pulp, and make full use of corn pulp
In benefit materials, add composite antioxidant, spirulina powder, calcium monohydrogen phosphate, cellulase, ethylmaltol, fishbone dust,
The a variety of feed addictives of small peptide chelated iron, Nattokinase improve the immunity of animal and improve feed digestibility.
Chinese patent 201710210039.X discloses a kind of pretreated corn pulp and its direct-injection in animal and fowl fodder
Application method is added sodium hydroxide solution adjusting corn into corn pulp and starches slurries pH to 5.2~5.3；Jade to after adjusting pH
Phytase is added in Rice & peanut milk；It is respectively connected to cultured bacillus amyloliquefaciens into the corn pulp after mould solution and aspergillus niger carries out
Fermented and cultured；Corn pulp direct spraying is put into animal and fowl fodder after culture.
Corn pulp processing method disclosed in the prior art, processing cost is high, and technique is cumbersome, and operation requires stringent, it is difficult to real
Existing industrialized production, is spray-dried the exhaust gas that Dried Corn Steep Liquor Powder generation is made and dust pollutes the environment.
