Patent ID: 7943765

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 components are prepared separately and individually, wherein the basic polysaccharide is plasticized, the networking polysaccharide is dissolved, and the components are mixed in a molecular disperse fashion, wherein the method comprises the following steps in at least one process zone: a) supplying a basic polysaccharide; b) adding a first softener to the basic polysaccharide to plasticize the basic polysaccharide to obtain a first fluid; c) dissolving a networking polysaccharide to obtain a second fluid by the action of a second softener, wherein in step c) the second fluid is overheated, a softener content WM d of the networking polysaccharide is in the range 40-99 wt.-%, a pressure p is identical to the water vapor pressure p w (T) at the respective temperature, a duration Δt d of the dissolving is in the range 5 sec-7 min, a heating rate v d is in the range 1-300° C./min, an overheating temperature T LÜ is in the range 80-260° C. and a pH of the networking polysaccharide is in the range 5-12; d) supercooling the second fluid to obtain a third fluid, wherein the softener content WM d of the networking polysaccharide is in the range 40-99 wt.-%, a pressure p is identical to a water vapor pressure p w (T) at the respective temperature, a duration Δt e of the supercooling is in the range 5 sec-7 min, a cooling rate v e is in the range 5-300° C./min, a temperature T L1 is in the range 0° C. to 0.9 T LÜ and a pH of the networking polysaccharide is in the range 5-12; e) incorporating the third fluid from step d) into the first fluid from step b); f) combining the fluids from steps b) and d) into a total mixture to form a polysaccharide network after steps a) to f) have been completed, wherein a shear velocity G d in the steps c) and/or d) and e) is in the range from 10/s to 100,000/s.
