Abstract
Even if freshly roasted and freshly ground coffee is used when percolating hot coffee, much or at least part of the fragrances and aromas originally contained in the coffee beans disappear into the environment instead of staying with the brew, therefore, in order to save these aromas and fragrances, a method and an apparatus is suggested with the help of which roasting and grinding of the coffee beans take place inside the flask where the beverage gathers, thus assuring that all or most of the aromas and fragrances generated during roasting and grinding stay contained in the flask until the coffee is served.
Claims17
An apparatus for making beverages from a commodity to be processed therein, comprising a pervious container (15, 115) having motivated blade means (12, 112) in said pervious container operable at selective speeds for respective roasting, grinding and stirring phases of a commodity in said pervious container;
- heating means (H.sub.2 H.sub.3) operable to heat a commodity for roasting thereof in said pervious container;
- flow means for effecting passage of a heated fluid into said pervious container to permeate through a commodity ground therein to produce a beverage flow into a flask;
- whereby a commodity may be heated and roasted at a preselected low blade means speed and ground at a preselected high blade means speed and subjected to flow of hot fluid therethrough while being stirred at a preselected low blade means speed to produce a beverage flow into a flask from said pervious container.
A food processing apparatus comprising a horizontal base, a vertical column standing on the base and a shelf supported thereon;
- a platform on said base and a flask carried on said platform below said shelf and slightly shorter than said column and having an open top;
- a perforated pot-like basket in said flask and a heating means therefore;
- a blade means having a blade inside the basket;
- blade rotating means comprising an electric motor having means for optionally slowly stirring the contents of said basket or rapidly grinding said contents;
- said apparatus further comprising a reservoir for liquids having heating means to produce hot fluids;
- duct means in said shelf connecting with said reservoir for conveying hot fluids from the reservoir to said basket to effect a brewed liquid seeping into said flask;
- said platform having a lever arm means operative to move said flask toward said shelf to a near closure position of said open top relative to said shelf or to effect full closure thereagainst to completely separate the flask interior from the outside atmosphere, thus ensuring that, optionally, a part or all of the aromas and fragrances emerging from the basket and brew remain in the flask until the brew is removed;
- blade lifting means for removal of the flask from the platform by lifting the blade means to at least partially release the basket;
- a cupola in the shelf for receiving at least a portion of said blade means when said blade means is lifted;
- said blade means comprising a shaft;
- said blade lifting means comprising nut and bolt members one of which is carried by said shelf and the other of which is secured to said shaft whereby relative rotation of said members effects lifting of said blade means;
- said lever arm means comprising a lever arm and means operated thereby whereby rotation of said lever arm in one direction from a central position lifts said flask and rotation from said central position in the opposite direction lowers said flask to facilitate removal in coaction with said nut and bolt members.
