摘　　要：本文提出并研究了中和液与结晶母液混合进料,TPCIX柱多级流化混合床吸附的味精脱色除铁新工艺。研究了K15+122混合吸附剂脱色除铁的适宜工艺条件并考察了TPCIX(Tipping Plate Continuous Ion Exchange Contractor)柱的工艺运转。新工艺对提高99％味精产率和总收率,改善技术经济指标具有建设性的意义。A new decoloring and iron-removing technology of gourmet powder was proposed and the mixing bed adsorption of multistage fluid bed (TPCIX colomn) was studied with the mixing feeding of neutralization liquid and crystallization mother liquid. The appropriate conditions of decoloring and iron-removing were studied and the technological operating of the TPCIX colomn was investigated. The new technology can increase the yield of 99% gourmet powder and the total yield and thus improve the economic and technical index.
