  • Patent number: 10667642
    Abstract: An embodiment of a machine for brewing a beverage such as coffee includes a chamber and a piston assembly disposed in the chamber. The chamber is operable to receive a liquid such as water and a flavor base such as ground coffee, and to allow the beverage to brew from a mixture of the liquid and the base. The piston assembly is operable to filter a solid such as spent coffee grounds from the brewed beverage by moving in a first direction, and to force the filtered beverage out of the chamber by moving in a second direction. By modifying or automating some or all steps of the French press brewing technique, such a machine may control one or more of the brewing parameters with a level of precision that yields brewed coffee having a uniform taste from cup to cup. Furthermore, such a machine may brew the coffee with a speed that renders the machine suitable for use by establishments that serve significant amounts of coffee.

  • Patent number: 10668401
    Abstract: An extractor may have a housing that maintains a solvent pool in which solids material being processed is immersed during operation. One or more bed decks can be positioned inside of the housing to provide multiple extraction stages. In some examples, the bed decks are arranged to provide one bed deck positioned at a vertically elevated position relative to another bed deck, thereby providing a drop zone where the solids material passing through the machine drops from the vertically elevated bed deck to a lower bed deck. To reduce the amount of solids material passing through the drop zone that becomes entrained in the solvent, the exactor can be configured with a settling zone. In some examples, the settling zone is formed by truncating the length of the vertically elevated bed deck, providing increased space and residence time for the solids material to fall out of suspension.

  • Publication number: 20140319071
    Abstract: The present invention is directed to a polymer dissolution system comprising a mix tank, a strainer, and a pump. The mix tank is configured to receive polymers, water, and an inlet stream, to form a polymer solution including swollen polymers, and to discharge the polymer solution. The strainer is configured to receive the polymer solution, and to withdraw at least a portion of the swollen polymers therethrough substantially without shear degradation, thereby forming a resultant solution, wherein the swollen polymers are dissolved at least in part. The pump is configured to receive the resultant solution, and to return the resultant solution to the inlet stream. In some embodiments, the strainer and the pump cooperate together to maintain a viscosity of the resultant solution substantially within a predetermined range.

  • Publication number: 20140271399
    Abstract: A method and apparatus for dispensing a solution of a solid product in a fluid. A freestanding apparatus comprises an inlet portion through which fluid enters, a reaction portion in which the fluid encounters and dissolves the product to form a solution, and an outlet portion from which the solution exits the apparatus. Fluid may encounter product from a single direction or multiple directions. The apparatus may be configured to receive a particularly shaped solid product, and may comprise a lid or gate to prevent fluid from contacting the product undesirably.

  • Patent number: 8815171
    Abstract: A cast solid product dispenser for controlling the inputs and operating parameters of dissolution of a cast solid product is disclosed. The dispenser (10) includes a housing (12) having a cavity (18) for removably receiving a container (14) holding a cast solid product. The dispenser (10) includes means for controlling the temperature and pressure of liquid used for dissolution of the cast solid product. The dispenser (10) also includes a pedestal (20) for maintaining a constant distance between the surface of the product and a nozzle (48) during dissolution. The dissolution cycle includes a pulse of spray generally followed by a delay to allow liquid used in the dissolution process to adjust to a desired temperature. A pressure regulator (42) adjusts the pressure variation between various liquid sources so both the pressure and temperature of liquid used in the dissolution process is generally constant.
