  • Patent number: 11890386
    Abstract: Disinfecting particulate material includes combining the particulate material with a photocatalyst to yield a mixture, irradiating the mixture for a length of time with pulses from a light source having broadband emission spectrum between 190 nm-1100 nm to yield an irradiated mixture, and separating the photocatalyst from the disinfected mixture to yield the disinfected particulate matter. Irradiating the mixture inactivates microorganisms in the mixture to yield a disinfected mixture. A system for disinfecting particulate material includes a pulsed light source having a broadband emission spectrum in a range between about 190 nm and about 1100 nm, a chamber defining a cavity optically coupled to the pulsed light source, a humidifier, a fan, and one or more sensors. The chamber includes a conveyor configured to accept the particulate material and arranged such that the pulses emitted by the pulsed light source irradiate the particulate material on the conveyor.

  • Patent number: 8110677
    Abstract: This invention relates to a method of extracting crude polysaccharide by microwave-assisted from Artemisia sphaerocephala seed de-oiling dregs. In particular, the invention comprising: microwave-assisted extraction, enzymatic hydrolysis, dialysis et. al. It provides a technique whereby the polysaccharide can be extracted effectively, in a relatively short period of time (20-30 min) with respect to conventional extraction methods and allows for an enhanced extraction yield (more than 30%). Furthermore, the invention also allows for the extraction of material with less solvent consumption, good reproducibility, excellent solubility, energy conservation, environmental protection, and showed great potential for efficient sample preparation and large-scale industrial application in the near future. With great resource advantage of Artemisia sphaerocephala in China, the invention has bright perspectives in promoting local economic development.
