Abstract: A cassette for producing coffee by the cup or pot and for use with a liquid receptacle having an internal locking flange. The cassette comprises a ring defining an interior and forming a bottom annular groove to receive the locking flange of the liquid receptacle and thereby to hold the cassette in place therein. The cassette further includes a plurality of ribs connected to and extending across the ring and separating the interior thereof into a multitude of sections, and coffee particles disposed in said sections. A bottom filter and a top filter are secured to the ring and extend across the bottom and top, respectively, of the interior of the ring to hold the flavoring particles therein. Preferably, the cassette is packaged in a sealed vacuum pack; and as it is so packaged, the mass of particles in each section of the cassette is reshaped slightly and formed into a firm conglomerate, which facilitates the subsequent flow of hot water through the cassette.

Abstract: The invention relates to a process for separating caffeine from caffeine-loaded active carbon in which a circulated inert gas sweeping stream is passed rectangularly through the stream of active carbon at a temperature of 350.degree. to 450.degree. C., and the caffeine desorbed from the active carbon is precipitated in the form of solid particles by quenching the inert gas sweeping stream, and separated.
Abstract: The insert container (1) for freeze-drying plants comprises a plurality of vertical ribs (4) subdividing the insert container (1) into parallel compartments (7). Vapor-pervious tubes (5) extend transversely of and traverse the ribs (4) preferably at about one-third of their height. The tubes (5) communicate with the ambient atmosphere through one or more vapor discharge channels (6) extending parallel to the ribs (4). The water vapor can also be discharged through channels (12) formed between the side walls (3) of adjacent insert containers (1).
