乳粉二级干燥实验研究

Experimental Investigation on Two-stage Drying of Milk Powder

乳粉干燥是耗能较大的一种操作过程,优化干燥过程具有十分重要的意义。通过实验研究二级干燥系统中振动动流化床干燥全脂淡乳粉、全脂甜乳粉及母乳化乳粉的性质,确定了合适的干燥工艺,并比较了3种乳粉振动流化干燥的不同特点。

Milk powedr was generally produced from milk through evaporating and drying operations. For drying was one of the most energy - consuming operation, it was of great interest to optimize drying process. The drying kinetics of three variants of milk powder( full-cream milk powder, full - cream sweeten milk powder and milk powder for babies) was studied in the after-dryer vibro-fluidized bed dryer, and then made out the feasible processes.
