摘要: 采用反渗透技术对籽瓜汁进行浓缩,分别研究了膜通量、压力、料液温度、籽瓜汁浓度等参数之间的关系,结果表明:反渗透膜对籽瓜汁有效成分的截留率接近100%,对无机盐截留率大于98%,籽瓜汁的最终浓缩浓度为20Brix;其它条件不变的情况下,膜通量与压力、料液温度成正比关系,与料液浓度成反比关系。Abstract: The reverse osmosis membrane seed-watermelon juice processing was introduced.The relationship between pressure, temperature, concentration and permeate flux in concentrated process were studied with reverse osmosis.Experimental results proved that the retention of valuable components of this system was approximation 100%.On inorganic salt interception rate was greater than 98%.The end of seed-watermelon juice concentrate concentration was at 20Brix.Case of other things, membrane flux was proportional to the pressure and the liquid temperature.Membrane flux and concentration had an inverse relationship.
