"IMPROVEMENTS IN THE PROCESS OF SUGAR CANDY MANUFACTURE AND APPLI-
ANCES THEREFOR." A communication from John Pitman, of Hong Kong.
This Invention has for its object the improvement of the process of manufacturing
sugar candy, and mainly consists as follows:-Carefully selected moist sugar is
mixed with a proportion of water in the proportion, say, of two parts sugar to one
of water, and boiled for a certain period in vacuum or in open iron pans, to each of
which is fitted a movable metal lined rim or hoop about a foot high, to prevent
the overflow of scum. Raw eggs in certain proportion are added (say about one to
the gallon), for the purpose of clarifying the mixture and collecting the dirty
particles. The mixture is then boiled slowly for a certain period, the scum which
rises during the process being removed by suitable colanders. After boiling the
required time, the syrup is strained through coarse cloth or metal strainers into
carthenware or metal pans, from which it is poured back again into the boiling
pans until it gains the proper consistency; when this has been reached, the syrup
is then poured into iron, metal, porcelain, or earthenware crystallizing pans,
perforated or not perforated, and in which reticules of bamboo, or wooden strips,
or network of thread with air tight covers have been previously fixed in such a
manner as to divide the mass into convenient sections when it solidifies about
them. The crystallizing pans are set on layers of grain husks or bran covered

of the year. When the crystallization is completed, the crust is broken and the
residual syrup poured off. The pans are now exposed to the sun or heated over
a fire, then carefully broken and the parts removed, releasing the crystallized
mass, which after withdrawing the bamboo strips is broken into fragments of 5
a size for sale. These are dried in the sun on bamboo matting when the candy
is ready for market.
The pans if carefully broken can be lashed up and used again.
After crystallization is completed and the crystals ready for removal, I can
apply a jet of moist steam for detaching the crystals from the sides of the vessels, 1
and also for washing the syrup from the crystals, and for drying the same I apply
a. jet of heated air, or I drain off the residium syrup, remove the candy from the
vessels, cleanse it if necessary, and dry it.

"IMPROVEMENTS IN THE PROCESS OF SUGAR CANDY MANUFACTURE AND
APPARATUS THEREFOR." (A communication from John Pitman, of Hong Kong.)
This Invention has for its object the improvement of the process of manufacturing
sugar candy, and consists as follows:-Carefully selected moist sugar is mixed with
water in the proportion, say, of two parts sugar to one of water, in open metal pans
of about three feet six inches diameter and two feet deep at centre, to each of
which is fitted a movable metal lined rim or hoop about a foot high to prevent the
overflow of scum, and raw eggs in certain proportions are added, say, about one to
the gallon, for the purpose of clarifying the mixture and collecting the dirty
particles. The mixture is then boiled slowly for a certain period, say, two hours,
over a fire or in vacuum, the scum which rises during the process being removed
by suitable colanders. After boiling the required time the syrup is strained through
coarse cloth or metal strainers into earthenware or metal pans, from which it is
poured back again into the boiling pans until it gains the proper consistency.
When this has been reached, the syrup is then poured into iron, metal, porcelain or
earthenware crystallizing pans, perforated or not perforated, and in which reticules
of bamboo, or wooden strips, or network of thread with air-tight covers have been
previously fixed, in such a manner as to divide the mass into convenient sections
when it solidifies about them. The crystallizing pans are set on layers of grain
husks or bran covered with matting and left for a period, which varies with the
weather and the season of the year. When the crystallization is completed, the
crust is broken and the residual syrup poured off. This can be afterwards used for
making sugar. The pans are now exposed to the sun or heated over a fire,
preferably charcoal, then carefully broken and the parts removed, releasing the
crystallized mass, which aftor withdrawing the bamboo strips, is broken into
fragments of a size for sale. These are dried in the sun for a day or so on bamboo
matting, when the candy is ready for market. The pans if carefully broken can be
lashed up and used again. After crystallization is completed and the crystals
ready for removal, I can apply a jet of moist steam for detaching the crystals from
the sides of the vessels, and also for washing the syrup from the crystals, and for
drying the same I apply a jet of heated air. Or I drain off the residuum syrup,
remove the candy from the vessels, cleanse it if necessary, and dry it.
Having now particularly described and ascertained the nature of the said
Invention, and in what manner the same is to be performed or carried out into
practice, I hereby declare that I claim the said Invention of "Improvements in
the Process of Sugar Candy Manufacture and Apparatus therefor," substantially as
herein before set forth and described.
In witness whereof, I, the said Thomas Morgan, have hereunto set my hand
and seal. this Tenth day of March. in the year of our Lord One thousand
THOS, MORGAN. (L.S.)
