  • Patent number: 10952453
    Abstract: Included is a brewing system that utilizes a curved pedestal that allows brewed effluent to drain in a manner that travels toward the center of the curved pedestal to maximize the exposure of the effluent to the organic material used for brewing, while also maximizing yield. The pedestal 112 sits above the lowest effluent level to allow the brewed effluent to drain from the organic material that is used for brewing to maximize the amount of effluent obtained. By allowing the brewed effluent to drain from the organic material, the weight and size of the organic material is reduced, so that the filter bag can be removed from the brewing system without ripping or tearing. The brewing system eliminates the need for a separate mesh bag and allows the effluent to drain without squeezing the filter bag and which would otherwise cause the release of harsh oils and acids, which can also be unsanitary as a result of a user handling the bag filter.

    Abstract: A coffee brewing device includes a housing for holding ground coffee with at least one wall of the housing being formed from a permeable filtering membrane which permits a flow-through of water. The interior of the housing is vented to the atmosphere through an attached conduit, which can be used as a handle, so as to permit the escape of gases which are generated when the coffee grounds are submerged in a cup of hot water. Baffles which serve to control the extent and direction of gas movement may be positioned in the housing. By such control, the generated gases may be utilized to agitate the coffee grounds to thus get a more complete mixing of the grounds with the water prior to a venting of the gases to the atmosphere. The baffles may be of both a perforated and non-perforated design so as to control gas bubble size and direction of flow.

  • Patent number: 3948157
    Abstract: A filter is provided for a brew cup for use in a hot beverage brewing machine such as a coffee brewing and dispensing machine. The filter is attached to the inside of a brew cup about halfway up the side walls and to the center of a guide spider axially movable within the brew cup. By this arrangement, spent grounds and fines are prevented from traveling with the brewed coffee or other beverage as it passes through the brew cup. When the brew cup mechanism is inverted and moved to the dumping station, this arrangement provides for the dumping of substantially all of the spent grounds and fines by a snap action applied to the spider and the filter material. The filter material is restrained from engaging the floor of the brew cup to prevent clogging and caking of the filter material and fines or spent grounds on the floor of the brew cup.
