Process for comprehensively utilizing steam exploded radix puerariae and device therefor
The invention provides a process for co-producing ethanol and Radix Puerariae flavones and utilizing Radix Puerariae fibers from Radix Puerariae by way of clean solid state fermentation, and the device used therein. The process comprises the following steps: providing Radix Puerariae as raw material; pretreating the Radix Puerariae raw material by steam explosion; producing and separating ethanol by continuous coupled solid state fermentation; filtering off fermentation residues; and extracting and purifying Radix Puerariae flavones from the filtrate. The process achieves an effective and comprehensive utilization of Radix Puerariae.
