  • Patent number: 10757963
    Abstract: A heat-transforming ceramic roasting cylinder and a coffee bean roaster using the same are provided. The ceramic roasting cylinder is made by grinding and mixing ball clay, kaolin clay, mullite, spodumene, and an energy ceramic material into a clay blank; molding the clay blank into ceramic green bodies; and sintering the ceramic green bodies at 1250˜1320° C. for 18˜24 hours. The ceramic roasting cylinder has an internal roasting space where coffee beans are loaded. The ceramic roasting cylinder also has evenly distributed capillary pores through which heat can circulate to induce the energy ceramic material in the roasting cylinder to release negative ions and far-infrared rays. The far-infrared rays can reduce the van der Waals forces between the oil molecules in the coffee beans instantly, splitting large oil molecules into smaller ones, ensuring the oil in the beans are released sufficiently, evenly, and rapidly to the vicinity of the bean surface.

  • Patent number: 4924765
    Abstract: Raw coffee beans or nuts are put in a revolving drum divided into at least four independant modular sectors each of which carries a given quantity of the product through a succession of similarly independent work stations to be heated, roasted, cooled and discharged ultimately through an outlet. The air used to cool the product is recycled from the roasting station, being drawn from the drum into a separator, freed of any skins or husks that may be entrained from the roast, then directed into a cooling system that lowers its temperature to sub-ambient level before returning it to the drum; the option exists of enriching the recycled air with additional aromas before it finally enters the cooling station.

  • Patent number: 4556450
    Abstract: An apparatus for removing water or other liquids from webs of such porous materials as fibrous paper webs coursing through a papermaking machine without substantially compacting the webs. The web which may be coherent or perforate passes over a sector of a cylinder having preferential-capillary-size pores through its cylindrical-shape porous cover. Preferably, the porous cover comprises hydrophilic material which is substantially non-resilient and which renders the surfaces of the porous cover wettable by the liquid of interest. A portion of the interior of the cylinder may be subjected to a controlled level of vacuum to effect pneumatically augmented capillary flow of liquid from the web; and another portion of the cylinder may be subjected to pneumatic pressure for expelling the transferred liquid outwardly through a portion of the porous cover which is not in contact with the web.

  • Patent number: 4517992
    Abstract: A tobacco treating apparatus including an outer, rotatable, hollow drum having a tobacco inlet at one end and a tobacco outlet at the opposite end with an inner, hollow drum extending through the tobacco inlet end, generally coaxial with the outer drum and extending a distance longitudinally into the outer drum a distance less than the entire length of the outer drum. The outer and inner drums cooperate to define an annular gas flow-through passageway which is open to an exhaust chamber. Tobacco to be treated is introduced into the inner drum and flows therefrom into the outer drum while a stream of tobacco treating gas is introduced into the tobacco outlet end to flow in counter-current direction to the flow of tobacco through the outer drum so that virtually all of the tobacco is contacted and treated by the gas. The treating gas leaves the outer drum through the annular flow-through passageway and into the exhaust air chamber from which it is exhausted from the apparatus.
