Embodiment 1
[0044] Such as figure 1 Shown, the invention discloses a kind of extraction process of erythritol, it comprises the following steps:
[0045] S1. Ceramic membrane filtration: the erythritol fermentation broth is eluted and filtered through a primary ceramic membrane to obtain a primary dialysate and a primary concentrated solution. The pore size of the primary ceramic membrane is 50-200nm.
[0046] S2. Nanofiltration filtration: the primary dialysate in step S1 is eluted and filtered through a nanofiltration membrane to obtain a nanofiltration dialysate and a nanofiltration concentrated solution. The molecular weight cut-off of the nanofiltration membrane is 200-1000 Daltons.
[0047] S3. Nanofiltration graded treatment: real-time detection of erythritol concentration on the nanofiltration dialysate in step S2, and graded treatment:
[0048] If the nanofiltration dialysate concentration is less than 13%, return to the aforementioned process for processing.
[0049] If the co...
Embodiment 2
[0052] Such as figure 2 Shown, the invention discloses a kind of extraction process of erythritol, it comprises the following steps:
[0053] S1, ceramic membrane filtration: pass the fermentation broth of erythritol (concentration 15%-20%, light transmittance>2%, electrical conductivity2%, conductivity 2%, electrical conductivity<2000μs / cm, PH3-5). The secondary concentrate is used as waste liquid for later treatment.
[0054] S2. Concentration: Concentrate the secondary dialysate in step S1 through a nanofiltration membrane with a molecular weight cut-off of less than 100 Daltons to obtain a concentrated solution (refraction ≥ 15%, light transmittance > 2%, conductivity 90%, conductivity < 200μs / cm). The permeate can be recycled for elution in the secondary ceramic membrane in step S1 and the nanofiltration membrane in step S3.
[0055] S3, nanofiltration filtration: the primary dialysate in step S1 and the concentrated solution in step S2 are eluted and filtered through...
