US 12,565,570 B2 · Foam manufacturing techniques

Abstract

A method of foam production is described. The method includes providing a foam precursor including one or more components, the one or more components including at least one of chitin, chitosan, or chitosan oligosaccharide and a solvent. The method further comprises exposing the foam precursor to radiation. The radiation is of a wavelength to heat the foam precursor. A system for foam produced is described, the system including a mixer configured to output a foam precursor including one or more components. The one or more components include at least one of chitin, chitosan, or chitosan oligosaccharide. The system further includes a radiation emitting system positioned to receive the foam precursor from the mixer and expose the foam precursor to radiation to heat the foam precursor to form a solid foam.

A method of foam production, comprising:

providing a foam precursor including one or more components, the one or more components including at least one of chitin, chitosan, or chitosan oligosaccharide and a solvent;
exposing the foam precursor to radiation, wherein the radiation is of a wavelength to heat the foam precursor;
evaporating at least some of the solvent by heating the foam precursor using the radiation to produce a solid foam including the at least one of the chitin, the chitosan, or the chitosan oligosaccharide, wherein the solvent includes at least one of water or acid responsive to the radiation;
and
inserting the solid foam into an oven, after exposing the foam precursor to the radiation, and heating the solid foam using a radiative heat source included in the oven to harden an exterior surface of the solid foam, wherein a density of the solid foam is less than 1 g/cm3.
