This disclosure relates to a method and a system for processing grapes. An example system includes a simulated moving bed (SMB) device configured to receive a feed stream and an eluent stream as inputs and provide an extract stream and a raffinate stream as outputs. The feed stream includes a grape juice, the extract stream includes a high-sugar grape juice, and the raffinate stream includes a low-sugar grape juice. The system also includes fermentation equipment configured to produce a low-alcohol wine from the low-sugar grape juice.

A simulated moving-bed type chromatographic separation method including: using a circulation system in which three or more unit packed columns each filled with an adsorbent are connected in series, dividing the circulation system into at least three-sections annularly continuous from an upstream side to a downstream side so that each section has at least one of the unit packed columns, and separating, by using an eluent, a weakly, a strongly, and an intermediately adsorptive component having adsorption performance on the adsorbent, which performance is intermediate between the previous two components, the weakly, strongly, and intermediately adsorptive components being included in a feed solution, wherein positions of supplying the feed solution, extracting the weakly adsorptive fraction, extracting the intermediately adsorptive fraction, and extracting the strongly adsorptive fraction have a specific relationship. A chromatographic separation system carries out the chromatographic separation method.

A simulated moving bed process using dual, parallel rotary valves configured or plumbed to be operated independently in which the step times of the rotary valves are staggered. In embodiments, the second rotary valve is programmed to step about halfway through the step time of the first rotary valve. Staggering the step time of the parallel rotary valves, rather than utilizing simultaneous stepping, results in increased net composite paraxylene concentration of the extract stream, allowing for increased capacity of the simulated moving bed process and/or reduced energy consumption.
