Liquids from the cookers 20 passes out through
a bottom drain pipe 23, to be pumped into stor

The. cooked products from the digestors are
hauled out through discharge doors 22', at the
bottom of the digestors into a receiving pan 24.
The cooked products are then transferred to hy

to extract the last of the fats and 'oils. From
»the presses the cooked products are conveyed
along a runway 26, to a grinder 21. After being
crushed in the grinder the ground products or

compartment 34 at the bow of the ship. The
variable cargo space represented by the cold
storage room I3 is amidships.

Since the arrangement of the propulsion ma
chinery and ?sh processing machinery is such
that the ship is neither down‘ at the bow nor
down at the stern when the storage room I3 is
empty. the ?lling of the storage room l3 will not
