Patent ID: 8153783

Claim:
A method for the production of a polysaccharide-based network, the method comprising: forming a polysaccharide-based network from a total mixture of components comprising at least one basic polysaccharide and at least one networking polysaccharide by one of homocrystallization and heterocrystallization, wherein the basic polysaccharide is plasticized, the networking polysaccharide is dissolved, and the components are mixed in a molecularly disperse fashion, wherein the method comprises the following steps in at least one process zone: a) supplying a basic polysaccharide; b) dissolving a networking polysaccharide to obtain a fluid by the action of a softener, wherein in step b) a softener content WM d of the networking polysaccharide is in the range 40-99 wt.-%, a pressure p is in the range of being identical to the water vapor pressure p W (T) at the respective temperature up to 100 p W (T), a duration Δt d of the dissolving is in the range 5 sec-7 min, and—provided that the networking polysaccharide is starch—a pH of the networking polysaccharide solution is in the range 5-12; c) incorporating the fluid from step b) to the basic polysaccharide from step a); d) combining the basic polysaccharide from step a) and the fluid from step b) into a total mixture, wherein the softener content WM 2 is less than 60% by weight, to form a polysaccharide network after steps a) to d) have been completed, wherein the basic polysaccharide is plasticized at the same time as the mixing to the total mixture takes place, wherein a shear velocity G d in the steps b) and c) is in the range from 10/s to 100,000/s.
