Abstract：

In consideration of the growing of planting bayberry scale, reducing the costs in bayberry juice storage and transport is an important issues that needs to be solved eagerly. This paper applied dish tubular reverse osmosis (DTRO) technology to concentrate bayberry juice. The experiment results showed that after three times concentration (by volume), the bayberry juice total acid increased from 10.23% to 30.05%, baume degree increased from 4.3 ºBe to 11.7 ºBe, the content of soluble soild increased from 7.35% to 19.5%. Additionally, taking the method of 2%C531+ NaOH (pH 11 ~ 11.5) to caustic clean, the membrane flux can be recovered effectively. The study verified the application of DTRO technology in bayberry juice pre-concentration, and determined a reasonable cleaning solution.
