GLASGOW COFFEE BOASTING WOEKS
AND GENERAL GRINDING MILLS,'
GR/CME STREET, GLASGOW.
DESIRES to intimate that he has now erected those new
and extensive Premises, upon the old site of ground, Macpherson
Street, with a.frontage to that street recently formed, called Graeme
Street, and has fitted up additional new Mills and Machines of differ-
ent kinds, with every improvement, in order to facilitate the opera-
tions of his trade in its various branches. And while it has been his
constant aim to supply the wants of his Customers with all speed and
convenience, hehas much pleasure in stating that he is now in a better
position than ever to meet the demands of Grocers, Confectioners,
Biscuit Manufacturers, Druggists, Dyers, Drysalters, etc., with all
the appliances which his new Machinery can afford.
A French scientific gentleman, who has directed his attention to this
subject, says : — " I have found that Coffee is better roasted, and more
of the aroma retained, when a double cylinder is used — the air be-
tween the interior and exterior cylinders acting as a non-conductor of
heat. It is done more uniformly, while the essential oil on which the
aroma depends is less liable to be dispersed than when exposed to the
fierce heat of a fire in a single cylinder.
In the double rotatory globular method of roasting as practised at
Mr Minto's Works, Grceme Street, Glasgow, the above principle is
acted upon, inasmuch as the globe (which has superseded the cylinder
since the application of steam power to this branch) revolves in a me-
dium of heated air, which experience has shown best prevents the dis-
persion of the essential oil or aroma.
