  • Publication number: 20210133371
    Abstract: Aiming at insufficient drying seafood on-board caused by hull swings, the present invention involves the establishment of location correction system for processing seafood transportation displaced by wind waves and anti-accumulation drying processing method. This invention employs CFD-DEM method to simulate the state and distribution of the material particles modulated by the deflector angle and wind speed. Finally, the optimized rotation angle of deflector and wind speed are obtained where material particles are equally distributed. Meanwhile, the uniform and fast drying of the marine products in the swinging hull are achieved. This invention shows the great advantages of high efficiency, automation and continuity.

  • Publication number: 20210065941
    Abstract: This invention relates to magnetocaloric materials comprising alloys useful for magnetic refrigeration applications. In some embodiments, the disclosed alloys may be Cerium, Neodymium, and/or Gadolinium based compositions that are fairly inexpensive, and in some cases exhibit only 2nd order magnetic phase transitions near their curie temperature, thus there are limited thermal and structural hysteresis losses. This makes these compositions attractive candidates for use in magnetic refrigeration applications. Surprisingly, the performance of the disclosed materials is similar or better to many of the known expensive rare-earth based magnetocaloric materials.

    Abstract: The present invention provides a method for extracting heat-sensitive Antarctic krill oil comprising the following steps. Firstly, frozen Antarctic krill is thawed and minced; a surfactant is added to the minced Antarctic krill to form a supercritical micelle system; extract the Antarctic krill multiple times after pressurizing and liquefying mixed gases; at the same time, a low-carbon alcohol solvent is added to strip the material in the critical micelle; after the extraction is completed, the extractant is removed; the extraction product and the residue after the extraction are subsequently collected; the heat-sensitive Antarctic krill oil can be obtained by high-speed centrifugal separation of the oil-water mixed extraction product. The present method has the advantages of simple operation, low extraction pressure and high safety. The extraction method of gas pressure liquefaction is completed under low temperature sealing conditions.

  • Patent number: 8796012
    Abstract: A technique for high sensitivity evanescent field molecular sensing employs a detection scheme that simultaneously couples a polarized beam to a single mode of a waveguide, and couples the polarized beam out of the waveguide to specularly reflect the beam by the same grating. Strong interaction with the single (preferably TM) mode is provided by using a silicon on insulator (SOI) wafer having a waveguide thickness chosen between 10-400 nm so that the majority of the mode field strength spans the evanescent field. Well known, robust techniques for producing a grating on the waveguide are provided. Interrogation from a backside of the SOI wafer is taught.
