An apparatus for sealing a bag of encased material is described. A plurality of nozzles radiate from a central vacuum system, each nozzle associated with a clamping means. A framework rotates about the central vacuum system. A holding tray and an elevating device are removably attachable to the framework. The holding tray is attachable below a one of the plurality of nozzles and comprises an upright section and a projecting section. The upright section is supported by the framework at an acute angle from vertical, a top end of the upright section being adjacent to the framework and a bottom end of the upright section being remote from the framework. The projecting section is removably attachable to the bottom end of the upright section and projects approximately normal to the upright section. The elevating device is removably attachable to the framework below a one of the plurality of nozzles. The elevating device comprises an upright section, a lower strut, and an upper strut, the upright section supported by the framework at an acute angle from vertical, a top end of the upright section being adjacent to the framework and a bottom end of the upright section being remote from the framework. The lower strut has a first end and a second end, the first end of the lower strut being attached to a first end of the upper strut and the second end of the lower strut being releasably attached to the bottom end of the upright section. A second end of the upper strut is releasably attachable to the top end of the upright section.
