Sugar
In the process of making muscavado sugar in Jamaica, the cane juice after
being brought to boiling point in an open kettle is transferred into a
second kettle, where it is treated and the heavy impurities allowed to
settle. The clear juice then goes into copper walls, a series of three
or more large open copper pans, called teaches. These pans rest above an
open fire fed by bagasse, cane trash and wood. After the juice has been
boiled to a certain density in the first pan it is transferred to the
second and the final concentration takes place in the third or fourth,
as the case may be. In some mills the last boiling is done with steam in
what is called an Aspinall pan, instead of over an open fire. When the
mass becomes sufficiently thick, it is put into large tanks and left to
crystallize. Sometimes it is kept in motion during crystallization, but
usually no stirring whatever is done. Crystallization completed, the
mass is packed in hogsheads with perforated bottoms. These hogsheads are
allowed to stand over drainage troughs for two or three weeks so that
the molasses may run off. The holes are then plugged up and the sugar is
ready to be shipped.
The percentage of sugar, glucose and water in Jamaica muscavados is
approximately:
No. 1 Sucrose 88.6 Glucose 5.30 Water 3.42
2 86.2 4.40 3.72
3 83.9 5.92 4.66
4 83.0 6.98 3.84
Management is slipshod and the extraction is poor. It takes fifteen tons
of cane and sometimes more to produce a ton of sugar.
As for the future of the sugar industry in Jamaica, much in the way of
improvement could be done by the introduction of systematic management,
proper cultivation, adequate fertilization and scientific methods of
manufacture. Labor is plentiful and cheap, and it would seem that sugar
could be produced in Jamaica at as low cost as in Cuba. Thus far,
however, there have been no signs of a real awakening.
As regards production, the following figures are taken from Willett &
Gray:
1903-04 crop 14,255 tons
1904-05 ” 16,000 ”
1905-06 ” 18,000 ”
1906-07 exports 13,971 ”
1907-08 ” 10,718 ”
1908-09 ” 11,453 ”
1909-10 ” 12,000 ”
1910-11 ” 19,960 ”
1911-12 ” 21,835 ”
1912-13 ” 8,728 ”
1913-14 ” 15,583 ”
1914-15 ” 15,063 ”
1915-16 ” 15,000[68] tons
