Definitions

  • the fluid flow system 62 shown in Figure 1 serves to maintain a constant temperature in the extraction zone 49 , and includes a controlled (e.g., constant) temperature bath 110 .
  • Heated fluid such as water or a silicon based heat transfer fluid from bath 110 enters heating jacket 66 through a conduit 112 , and exits through a conduit 113 , to maintain tobacco material 47 and extraction solvent in extraction zone 49 at a controlled temperature.
  • Means for heating the fluid and supplying the fluid to the heating jacket will be apparent to the skilled artisan.
  • the driving mechanism turns housing 123 to rotate the housing with attached plate 122 to align a tobacco material filled cell, shown in Figure 3 in communication with the pressure chamber at index position P , with the aperture in ceramic plate 120 .
  • the aperture in ceramic plate 120 communicates with chamber 50 .
  • another cell in the driving mechanism aligns with the tobacco material supply system 56 at index position L .
  • Piston 152 then extends to load tobacco material into the pressure chamber 50 as shown in Figure 3.
  • Other methods and components for introducing tobacco material into the chamber will be apparent to the skilled artisan.
  • housing 123 rotates to index the cell to position R .
  • a cell occupying position R at the input mechanism 54 is illustrated in Figure 4. The pressure remaining in a cell indexed to position R from position P is reduced and the discharged extraction solvent is sent to recovery system 106 through conduit 160 . The cell is then indexed to position L for loading of tobacco material.
  • Advanced structural ceramic materials typically have an adequate tensile strength to provide sealing surfaces for the dynamic seal of the present invention. Tensile strength is determined in accordance with ACMA No. 4 to be at least about 100 MPa. Typically, for most applications, a tensile strength of at least about 125 MPa is desirable, more preferably greater than 150 MPa, frequently greater than 200 MPa or more, and typically in the range of from 100 to 400 MPa or more.
  • An advanced structural ceramic material comprised of about 85 percent alumina typically has a tensile strength of about 155 MPa; 90 percent alumina, about 221 MPa; 99.5 percent alumina, about 262 MPa; and 99.9 percent alumina, about 310 MPa.
  • Advanced structural ceramic materials comprised of silicon carbide typically have a tensile strength of about 307 MPa, while that comprised of zirconia typically has a tensile strength of about 352 MPa.
