Abstract: 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.

Abstract: A method for producing ethanol from steam-exploded sweet potato by fermentation includes subjecting sweet potato to a steam explosion treatment, subjecting the sweet potato after the steam explosion to saccharification and fermentation, and collecting ethanol produced by the fermentation. The sweet potato can optionally be subjected to a pre-treatment utilizing a short-time, low-pressure steam explosion technology, which omits the long-time cooking process for the starch-based raw material and reduces the energy consumption for producing ethanol by fermentation.
