Within Drum Patents (Class 34/520)
  • Patent number: 9127882
    Abstract: The invention provides a method for the drying of a wet substrate, the method comprising treating the substrate with a solid particulate material at ambient or elevated temperature, the treatment being carried out in an apparatus comprising a drum comprising perforated side walls, wherein the drum comprising perforated side walls is rotated so as to facilitate increased mechanical action between the substrate and the particulate material. Preferably, the drum comprising perforated side walls has a capacity of between 5 and 50 liters for each kg of fabric in the load and is rotated at a speed which generates G forces in the range of from 0.05 to 0.99 G, and the method is carried out at a temperature of between 5° and 120° C. Preferably, the solid particulate material comprises a multiplicity of particles at a particle to fabric addition level of 0.1:1-10:1 by mass, wherein the particles comprise polymeric particles, non-polymeric particles, or mixtures of polymeric and non-polymeric particles.

  • Patent number: 7980002
    Abstract: The invention relates to a rotary drum in which the hygienic status of pourable solids separated from liquid cattle manure is modified by aerobic heating in such a manner that said solids can be reused as bedding in cattle sheds. The object of the invention is to obtain a high loading factor amounting to 60-70% filling of the drum which is located horizontally for installation in an insulated container. In accordance with the invention, the loaded solid is kept in a chamber and is only transferred to the drum when there is no solid surrounding the chamber. The crucial element is a flap of the chamber which only opens and closes in this area. If there is any solid resting on the outside of the flap then opening of the flap is prevented.

  • Patent number: 7941937
    Abstract: A laundry drier control method reads a temperature variation rate per unit time, to enable drying according to the amount and type of an object being dried. The method includes steps of initiating a drying procedure; measuring a temperature variation rate per unit time over the drying procedure; calculating an overall drying time based on the measured temperature variation rate per unit time; and performing the drying procedure for the calculated overall drying time. The drying time determining step is repeated if a substantial increase in the temperature variation rate is detected.

  • Publication number: 20100199514
    Abstract: An improved system for processing a liquid manure and producing organic fertilizer includes equipment for separating various solid components of the liquid manure having different nitrogen to phosphorous ratios and then mixing these components so as to produce an organic fertilizer with a predetermined nitrogen to phosphorus ratio. The system includes equipment for separating solid manure components and clarified water. Solid manure components include fertilizer, fodder/bedding material, and biomass. Fertilizer and clarified water are used to fertilize and irrigate the farming soil. Fodder is used as a bedding material for the animals or as a feed source. Biomass is used as a fuel source for running farming equipment and processes that require energy.

  • Patent number: 6397494
    Abstract: The invention relates to a process for drying melamine wet cake to produce a dry melamine powder showing improved bulk properties, the drying being effected with a contact dryer. In particular the invention relates to a process for drying melamine wet cake that contains predominantly melamine crystals that have crystallized from a melamine solution in a crystallizer, the drying being effected with a contact dryer. The invention also relates to the drying of a melamine wet cake whose percentage of fines having a diameter of <21 &mgr;m is less than 30 wt. %, the drying being effected with a contact dryer.

  • Patent number: 6090423
    Abstract: A method for roasting legumes such as soybeans to enhance their nutritional properties. Raw legumes are introduced to a roaster having an oven section and a steeping section downstream of the oven section. The raw legumes are heated to a selected roasting temperature in the oven section as they are moved through the oven section to and through the steeping section. Throughout the passage of the legumes through the oven and steeping sections the legumes are mixed continuously.
