For thermal processing, two duplicate 307 409 metallic cans
(No. 2) were filled with liquid (1% CMC solution) and particle (as
outlined in experimental design) mixture leaving a 12 mm headspace
and were held vertically in the reciprocating cage inside
the retort, equidistant from the axis of reciprocation (Fig. 1). The
empty space in the cage was filled with dummy cans to provide
for some ballast load. Retort was closed from the top and locked.
Motor was turned on and set at the required reciprocation frequency.
Steam was turned on and retort was heated up to
