  • Publication number: 20200147531
    Abstract: The present invention relates to the field of filtering, more precisely the present invention concerns an apparatus and a method for the separation of dry matter from a medium and the use of said apparatus. One embodiment discloses an apparatus for the separation of dry matter and liquid from a medium, comprising a plurality of press rollers, a separation chamber for receiving the medium and defined, in cross section, by the press rollers, and at least one chamber filter located inside and enclosed by the separation chamber. The apparatus is preferably configured such that a negative pressure can be established in said chamber filter(s) relative to the separation chamber such that liquid in the medium can be sucked into the chamber filter(s) and dry matter in the medium can pass between corresponding press roller.

  • Patent number: 9409105
    Abstract: The present invention relates to a filtering apparatus and method for mixing a compound of solid and fluid phases, separating the phases and/or extracting fluid from the compound. One embodiment of the invention discloses a filtering apparatus comprising a first filter section accommodating a first group of filter members, and a second filter section accommodating a second group of filter members, a piping system providing pipelined fluid communication between the filter sections and between a filter section and said filter section's corresponding group of filter members, the piping system configured such that the filter members form filtered fluid openings of the filtering apparatus, and circulation means, such as a pump, configured for passing fluid in a forward flow and/or in a reverse flow between the filter sections. In particular the invention may be used for the mashing process in a beer brewing procedure.

  • Patent number: 7882960
    Abstract: The invention relates to an apparatus for continuous separation of dry matter from a fluid, comprising an enclosed environment capable of being under vacuum or under positive pressure, in which enclosed environment a number of rollers (1, 3, 4, 4?, 6, 6?, 20, 21, 22, 23) form a chamber which is divided into two or more compartments (12, 13, 24, 27, 25, 26) by filtration means (7, 8, 16, 29, 36, 37, 38, 40), wherein one or more filtrated chambers (9, 10) are placed on the pure side of the filter means. In order to allow for cleaning and/or maintenance of the filtrate chambers, additional filtrate chambers are provided, which are separated from the first filtrate chambers by a wall. One of the filtrate chambers at any time is placed under the filter, while the other filtrate chambers are situated outside the enclosure for maintenance/cleaning.

  • Patent number: 7651619
    Abstract: A method and an apparatus for separating dry matter from liquid includes an enclosed separation environment capable of being pressure regulated. Within the enclosed separation environment, a suspension is brought into contact with at least one filter so as to accumulate dry matter on the at least one filter. The filter with the dry matter passes through at least one set of rollers such that liquid is removed from the dry matter on the at least one filter to form a substantially dry filter cake. Thereafter, the substantially dry filter cake is removed from the at least one filter. The above steps are performed in the enclosed separation environment either under vacuum or overpressure. The invention may be used in various fields such as the food industry.

  • Publication number: 20030146174
    Abstract: The present invention concerns a method and an apparatus for separating dry matter from liquid, comprising providing an enclosed separation environment capable of being pressure regulated, and in said enclosed separation environment contacting at least one filter with a suspension accumulating dry matter on the at least one filter and passing the at least one filter through at least one set of rollers, whereby liquid is removed from the at least one filter, followed by removing the substantially dry filter cake from the at least one filter, wherein the above is performed in the same enclosed separation environment either under vacuum or overpressure.

  • Patent number: 4237981
    Abstract: A horseshoe includes a horseshoe base which corresponds to the actual configuration of a horse's hoof. The base is mounted on the hoof so as to leave a space between a sole of the hoof and an upper surface of the base which faces the sole surface when the base is installed on the hoof. A filler material is filled in the space so as to support the hoof on the base when the latter is installed on the hoof.
