Abstract
A fluid pressure treating apparatus including a cylindrical tubular shell with a reciprocal spool assembly mounted for movement between a loading position outside the shell and a treating position within the shell, sealing members on said spool assembly for engaging the shell to form the pressure chamber. Conduits are provided to introduce processing fluid into the pressure chamber.
Claims43
A system for use in a process for increasing the filling power of tobacco comprising:
- (a) a pressure vessel including a cylindrical tubular shell and a spool assembly means movable between at least a first position outside the shell and a treating position within the shell, said spool assembly including first and second circular end members, connecting rod extending between and securing said first and second end members together and sealing means with at least one sealing member circumscribing each end member, said sealing members contacting the inner surface of said shell when the spool assembly means is in the treating position so that said shell, end members and seal members form a pressure chamber and said connecting rod acts as a tension member to carry loads applied to said end members when such chamber is pressurized;
- (b) means for moving the spool assembly means between at least a first position outside said tubular shell and the treating position;
- (c) means for loading and unloading material to and from said spool assembly means when said spool assembly means is outside the tubular shell;
- and
- (d) means for introducing a processing fluid into said pressure vessel when said spool assembly means is in said treating position, whereby said material contained therein is impregnated with said processing fluid.

An apparatus for treating material with fluid under pressure comprising:
- (a) a cylindrical tubular shell;
- (b) spool means mounted for reciprocation between a first position wherein at least a portion of said spool means is outside said shell and a treating position within said shell, said spool means including first and second cylindrical end members and a connecting rod for spacing and securing said end members together;
- (c) sealing means associated with said cylindrical end members and the inside surface of said shell which are engaged when said spool means is in the treating position so that said shell, end members and sealing means form a pressure chamber and said connecting rod acts as a tension member to carry loads applied to said end members when said chamber is pressurized;
- (d) means for introducing and removing a processing fluid to and from said pressure chamber;
- and
- (e) means for moving said spool means between said first position and said treating position.

- (d) means for introducing and removing a processing fluid to and from said pressure chamber including conduit means within said spool to permit the introduction of processing fluid within the center of said material;
- and
- (e) means for moving said spool means between said first position and said treating position.
