Abstract
[Objective]The research aimed to optimize the spray drying technology of the concentrated solution of monascus yellow pigment. [Method]The suitable drying aid and its addition amount and the suitable ranges of hot air rate, inlet temperature and feed flow rate were selected out through carrying out single factor drying experiments with spray dryer. [Result]The single factor experiments showed that the optimum drying aid was malt dextrin and its suitable addition amount was 10%; when the hot air rate was 1.00, 1.10 and 1.20 m~3/min, the yield rates were 20.50%, 24.82% and 18.64% resp.; when the inlet temperature was 90, 100, 110 and 120 ℃, the yield rates were 21.34%, 26.62%, 24.50% and 20.08% resp.; when the feed flow rate was 0.02, 0.04 and 0.06 cm~3/min, the yield rates were 22.58%, 24.68% and 18.26% resp. In the practical operation process, the optimum conditions for the spray drying technology of monascus yellow pigment were as follows: the addition amount of malt dextrin was 10%, the inlet temperature was 100 ℃, the hot air rate was 1.10 m~3/min and the feed flow rate was 0.04 cm~3/min. [Conclusion]This experiment provided basis for the application of spray drying technology in drying monascus yellow pigment.关键词
