  • Patent number: 11130304
    Abstract: A low speed seed oil expeller press with the capability of extracting oil through a new seed compression design that eliminates the need for filtration, and maintains the captured seed oil at a temperature below 130 degrees F. It has a seed preheating capability and controls the pressure and extraction oil temperature by adjustments of the expeller speed, the head volume and the size of the pressed seed exit orifice in the thorn. The seed oil expeller press eliminates seed rotation within the head volume so as to eliminate crushing, grinding or tearing of the seed by a symmetrical knived press head. The seed oil expeller press regulates seed temperature, seed feed rate, seed pressure, seed rotation and extracted seed oil temperature so as to compensate for the seed size, seed hardness and seed oil content.

    Abstract: The method includes the following steps: (i) feeding a slurry into the inlet of a press; (ii) removing liquid from the slurry as the slurry advances through a deliquefying section of the press, thereby producing a pressate stream; (iii) forming a plug of material as the slurry is advanced through a plug formation section of the press; (iv) advancing the plug of material to a discharge section of the press; and (v) removing additional liquid from the plug of material by operating the press so that the pressure in the discharge section of the press is greater than the pressure of the pressate stream by at least 2 psi. There is also described a method for controlling discharge consistency from a press, without provision of discharge restrictors, by varying a pressure differential between a discharge section of the press and a pressate stream.

    Abstract: An initial processing of natural raw rubber through an initial processing machine, comprising the steps of: (a) providing a coagulated latex which contains water and volatile compositions; (b) dewatering the coagulated latex through a screw-pressing process to remove free water; (c) forming a first pretreated latex material; (d) aging the first pretreated latex material through an aging process to remove water and volatile compositions; and (e) forming a final product of aged latex material. The screw-pressing process makes use of the temperature and pressure increase along the elongated channel structure. The aging process makes use of the further temperature and pressure increase of the rubber materials, together with the screwing effect of the screw-shaft component, the squeezing effect of the nozzle and additional heating at a particular location, which is around the mouthpiece of the nozzle to complete the aging process, which is energy saving, effective and efficient.

  • Patent number: 7964105
    Abstract: A method for increasing the removal of a higher fraction of liquid from the press cake in any belt press is described. Specifically, the invention incorporates a series of rollers that create multiple pinch points to compress the solid fraction while removing liquid. After each pinch point, the solid material is allowed to separate from the belt, fall by gravity, and repack so that more liquid can be released at each successive pinch point than is possible if the material is fed to multiple rollers and pinch points in series without decompressing as is done is prior art.

  • Patent number: 7946225
    Abstract: A system for extracting liquid from a mass comprising a portable platform having an upper surface, a system mass input, a polymer feeding and blending system on the upper surface, a liquid extraction assembly on the upper surface, and piping having a first section between the system mass input and the polymer feeding and blending system, and a second section between the polymer feeding and blending system and the liquid extraction assembly. The system is configured to have mass inputted into the system mass input, transport the mass to the polymer feeding and blending system through the first section of the piping, inject polymer into the mass in the polymer feeding and blending system, and transport the mass from the polymer feeding and blending system to the liquid extraction assembly. Pressure from mass forced into the liquid extraction assembly forces liquid in the mass to exit the mass.

  • Patent number: 7794568
    Abstract: Methods for dewatering a fiber suspension in a twin-wire press, having a lower wire and an upper wire, and a first and a second dewatering table, which supports the wires such that a dewatering space is defined by the wires, are disclosed. The wires transport the fiber suspension under compression of the wires by the dewatering tables, such that the fiber suspension is dewatered and forms a fiber web between the wires. A separate pressing force is applied against one of the wires, such that this wire presses the formed fiber web via the second wire against one of the dewatering tables and further dewaters the fiber web. The separate pressing force is adjusted such that a desired dryness of the fiber web leaving the dewatering tables is achieved. A twin-wire press is also disclosed.
