Improvements in or connected with the Manufacture of Sugar.
I, WILLIAM POWELL, of 4, Prince's Gate Wost, Prince's Road, Liverpool, in
the County of Lancaster, Sugar Merchant, do hereby declare the nature of this
invention to be as follows:
-
This invention consists in the manufacture or production of lump sugar,—that
is, sugar cubes such as are chiefly used for sweetening beverages of various
colours or hues; and this production or manufacture is effected by charging
sugar, when in the solid state, with a more or less transparent coloured liquid,
so that it has a bright and lightly tinted or coloured, and pleasing appearance..
In one case, in the manufacture of lump sugar, while the sugar is in the solid state
within the forms or moulds in which it is made, the coloured or tinted liquid-
which consists of water coloured by a suitable colouring matter is poured onto
the solid sugar, and is absorbed by it, and imparts to it the tint or colour of the
liquid; and when the blocks or slabs are cut or broken into lumps, they-the
lumps present a tinted or coloured light, semi-transparent, and bright appearance.
Amongst suitable colours or tints in which the sugar is produced, are pinks,
rose, lilac, or bright purples, violet, light or azure blue, lemon, yellow, green,
and other similar or like colours and shades.
In some cases, the slabs or the cut lumps are immersed in the coloured or
tinted liquid; or the liquid is sprayed onto the blocks or slabs or the out lump-
when out of the forms or moulds.
Improvements in or connected with the Manufacture of Sugar,
I, WILLIAM POWELL, of 4, Prince's Gate West, Prince's Road, Liverpool, in
the County of Lancaster, Sugar Merchant, do hereby declare the nature of this
invention and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement:-
This invention consists in the manufacture or production of lump sugar, that
is, sugar cubes such as are chiefly used for sweetening beverages of various
colours or hues; and this production or manufacture is effected by charging sugar,
when in the solid state, that is, when in solidified slabs or blocks, with a more or
less transparent coloured liquid, so that it has a bright and lightly tinted or
end and pleasing appearance.

page_text: As stated, the treating of the sugar is affected after it has been made and
brought, in its manufacture, to the solid condition; and the stage of manufacture
at which the treating or colouring operation is preferably effected, is that, when
the solidified sugar is in the moulds or forms in which it is solidified, and still
in a moist state. That is, the tinting or colouring is effected by the employment
of a tinted or lightly coloured liquor used for the "liquoring" process or action
in lump sugar manufacturing, where in this colouring mattor is passed through
the sugar while in the moulds, and produces both the normal effect of liquoring,"
and the tinting or colouring action; the result or effect of which is, that while the
sugar is tinted or shaded throughout a delicate colour or tint, it reserves the full
brilliancy of the crystal, so that its appearance is a tinted brilliant crystalline
lump. After this combined " liquoring" and colouring or tinting operation,
the sugar is dried and taken out of the moulds in any known suitable way.
Amongst suitable colours or tints in which the sugar is produced, are light pink,
light rose, light lilac, light violet, light or azure blue, bright lemon, light green,
and other similar tints or shades of a like nature; and the colouring matter
used, may be vegitable or aniline, or both.
The sugar made in this way preserves its natural characteristics, namely, it
has the appearance of ordinary white brilliant lump sugar, with a shade or tint
of the colour such as referred. to.
In some cases, the slabs or the cut lumps are immersed in the coloured or
tinted liquid; or the liquid is sprayed onto the blocks or slabs or the cut lump-
when out of the forms or moulds.'
Having now particularly described and ascertained the nature of this inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is:-
1. The new or improved article of manufacture, consisting of light semi-trang-
parent tinted or coloured lump sugar, in which the colour or tint in it, consists
of a light and transparent shade or tint introduced into the sugar after solidifi-
cation in its manufacture; substantially as set forth.
2. The manufacture or production of tinted or coloured lump sugar, consisting
in first producing solidified crystal sugar in moulds, and then, while in the mould
and moist, passing into or through the sugar a coloured or tinted liquid in the
liquoring operation, and in the apparatus in which the liquoring operation is
conducted; and then subsequently drying the sugar; substantially as set forth.
3. The manufacture or production of tinted or coloured lump sugar, consisting
in passing through the sugar during its manufacture, and subsequently to its
solidification in the moulds in which it is cast, a light tinted or coloured liquor;
and then subsequently drying the same; substantially as set forth.
