  • Patent number: 6502326
    Abstract: A method and apparatus for reducing the moisture content bound by capillarity in fiber cells of solid materials containing carbon. The material is ground and screened to form a loose sheet of the solid materials and/or sludges. The material is processed by screening and grinding methods for a plurality of hoppers for different grain sizes and grain size distributions. A thin layer of fines is spread as a first layer onto the spreading, feeding and filter belt, and a substantially thicker coarse material layer is formed as a second layer to form a sandwich of the material. The fines layer depth HF and coarse material depth HG of the sandwich correspond to the consistency and the proportion of the fines of the material. The sandwich formed is then carried by a belt into the pressure chamber of the filter press according to the dewatering cycle, while simultaneously the squeezed-out dry material is carried away.

  • Patent number: 6167637
    Abstract: The hydroextractor disclosed has a dehydration chamber, a pressurization chamber defined by a flexible diaphragm in isolation from the dehydration chamber, and a crushing member disposed in the dehydration chamber. A pipe member extends through the pressurization chamber and the diaphragm, and a rotary shaft extends sealingly through the pipe member into the dehydration chamber. The crushing member is mounted to the rotary shaft and is driven by a drive apparatus connected to the opposite end of the shaft. The hydroextractor feeds moist material and pours cooling water into the dehydration chamber and introduces pressurized water into the pressurization chamber. The hot material fed in the dehydration chamber is pressure-dehydrated into a cake with the diaphragm of the pressurization chamber. The dehydrated cake is poured with cooling water, and at the same time the crushing member crushes the dehydrated cake and mixes it with the cooling water.

  • Patent number: 6052919
    Abstract: In a process for making plastic granulate, a polymeric material is plastifyed into a plastic mass which is divided into single plastic strands. After pressing the plastic strands in a stream of cooling liquid, the plastic strands are shredded in the cooling liquid into granules, thereby forming a dispersion which is conveyed through a first conduit to a separator. The dispersion is concentrated in the separator by withdrawing a portion of cooling liquid, and subsequently transported to a dryer along a second conduit which is longer than the length of the first conduit. In the dryer, the cooling liquid is separated from the granulate.

C. to less than about 80.degree. C. while maintaining a relative humidity of the circulating air in the range about 1% to 30%, the drying apparatus comprising a dehumidifying device for dehumidifying air, a temperature-moisture controlling device, and a drying room. The tea made from this process is capable of being subsequently stored at room temperature and substantially retains flavor-producing volatile constituents.

  • Patent number: 5581907
    Abstract: An article to be dried is transferred and pressed and held between a wire endless conveyor and a flexible conveyor. The wire endless conveyor is placed between a nozzle, including a sucking-out nozzle and a blowing nozzle, and the cushion conveyor to press, hold and transfer the article to be dried. The nozzle dehydrates/dries the article to be dried. When an article to be dried is narrower than the width of the nozzle, the area where the article to be dried does not cover the sucking-out nozzle or the blowing nozzle is automatically shut by the flexible conveyor. The article to be dried is dehydrated/dried while it is pressed, held and transferred so that a high speed air jet stream and high speed negative pressure air stream do not flow out/in to outer air. While the article to be dried is transferred, pressed and held by the flexible conveyor, water adhering to it is formed into minute water drops by the high speed air jet stream and the high speed negative pressure air stream.

  • Patent number: 5522157
    Abstract: Stacks (16) of sheet material are moved on a conveyor (12, 14) between air manifolds (18, 20) and guide pins (19, 21); so that, drying gas is directed between the sheets of the stacks to cause the stacks to expand to form fluffed stacks 28 through which air moves readily to dry the sheets. A compression roller (26) is used to expel air from the fluffed stack and return the stack essentially to its original height. A reduction in tendency to curl is achieved in low relative humidity environments for sheets of photographic film.
