Vertical plug-flow process for bio-conversion

摘要

The present invention relates to a method of producing a solid conversion product of a substrate comprising the following steps: Optionally carbohydrates and proteinaceous substances derived from fava beans, peas, sunflower seeds, lupines, grains, and/or grasses. Preparing a substrate of biomass comprising carbohydrates and proteinaceous matter derived from soybean, rape seed, or mixtures thereof, in a further mixture having a matter , ● The ratio of the wet bulk density of 0.60 to 1.45 to the dry bulk density in the mixture of the substrate with a living microorganism or a combination of living microorganisms, which is not a living yeast or a combination of living microorganisms, and Adding water in an amount to provide an initial culture mixture having a moisture content of 30 to 70% by weight; -Incubating the initial culture mixture for 1-240 hours at a temperature of 15-70 °C; And thereafter recovering the wet solid conversion product from the culture mixture. The incubation step is continuous in a vertical, non-agitated culture tank with outlet means and additives for the solid conversion product and inlet means for the mixture. It is carried out as a plug-flow process.
