  • Patent number: 6165519
    Abstract: A filter for the adsorption of ingredients from and/or the dispersion of ingredients into a fluid includes a matrix which has a plurality of particles having an inherently active surface or an active surface made of a fluid treating material. The particles are held in place by a moderately viscous binder which is impervious to the flow of the fluid. The particles, however, are made of a fluid pervious material. An insufficient amount of binder is incorporated in the matrix to otherwise completely cover the particles. Thus portions of the active surface of the particles remains exposed to the flow of fluid thereby resulting in tortuous paths of flow through the matrix, thereby assuring contact with the treating particles.

  • Patent number: 6004593
    Abstract: Coffee of a generic flavor coming from the natural coffee bean is brewed and custom flavored in a method having the steps of (1) brewing the coffee in a brew chamber and passing the coffee through a filter to produce filtered filtrate of the brewed coffee at the downstream side of the filter, and (2) exposing a flavoring agent to the filtered filtrate at said downstream side of the filter to thereby add flavor associated with the flavoring agent to the filtered filtrate. The steps of producing filtered filtrate and adding flavor thereto are substantially separate and sequential as to each increment of filtered filtrate so produced and to which the flavoring agent is so exposed.

  • Patent number: 5958479
    Abstract: An antioxidant composition which utilizes a desiccant carrier impregnated with a suitable fat soluble antioxidant is conveniently contained within a vapor permeable housing to prevent homogeneous mixing thereof with a stored product when the composition is provided in granulated form. The desiccant carrier is selected from a group of suitable hydrophilic materials which demonstrates the capacity for reducing levels of atmospheric moisture by absorption thereof, including for example, silica gel. The housing may conveniently be a sealed packet formed from a porous fiber material, such as, for example, that commonly used for fashioning tea bags and the like. Alternatively, the housing may include an enclosed perforated structure, the perforations of which are smaller than the granules of the contained composition. Where the composition is provided in the form of a unitary body, a housing need not be used.

  • Patent number: 5906845
    Abstract: Methods and devices for flavoring liquids are disclosed. Flavoring solids such as particulate coffee solids are packed into an impermeable container, preferably occupying most or all of the available volume. Absorbed in the solids is a quantity of extractant liquid, preferably alcoholic liquor but others are possible. The amount of extractant is no more than can be taken up by the solids; there is no free liquid. The extractant pre-extracts flavoring components from the solids. One or more seals are removable to expose openings of the container. The openings may be closed by an integral filter, or a filter may be provided by an auxiliary device which holds the container. With the seals removed, the solids charge can be rinsed with liquid to be flavored, washing out the pre-extracted flavoring components.
