The fruit should be gathered in when in a blood-ripe state, to all
appearance like cherries. The labourers are principally accustomed
to reap the crop in baskets, of which they carry two to the field;
and when the coffee is bearing heavily, and is at its full stage of
ripeness, the good pickers will gather in four bushels _per diem_,
and carry the same on their heads to the works.
The fruit is then measured and thrown into a loft above the pulper
in a heap. It should be submitted to the first process of machinery,
the pulper, within twenty-four hours after, if not immediately; but
it not unfrequently happens that the manager is unable to pulp his
coffee for two and sometimes three days, by which time fermentation
ensues, and it becomes impossible after pulping to wash off the
mucilage, which rather adheres to the outer envelope of the berry,
and gives the produce what is termed a "red" or "blanketty"
appearance when spread out on the barbacues. The produce is let down
by means of a small hole cut into the floor of the loft, or a
floating box, into the hopper of the pulper, and by means of a
grater forcing the fruit against the chops, the berries are
dislodged from the pulp and fall upon a sieve, which being shaken by
the machinery, lets the berries fall into the cistern, whilst the
grater catches the pulp and carries it backwards at each evolution
of the roller, around which it is encircled.
The fruit which might have passed through without being more than
half squeezed, and having only ejected one berry, is then returned
(after being shaken off by the sieve) into the hopper, to undergo
the process a second time. The pulped coffee is then permitted to
remain in the cistern for a day and a night, during which period it
undergoes a process of fermentation; it is then washed out in two or
three waters, and the whole of the mucilaginous stuff which had
risen from the berry by the fermentation is entirely washed off, and
the coffee presents a beautiful white appearance. From this the
produce is turned out to drain on a barbacue, sloped so as to throw
all the water to the centre, where a drain is placed to carry it all
off.
