PROVISIONAL SPECIFICATION.
An Improved Preparation of Tea and the Process of Making
the same.
I, WILLIAM CAREY LEECHMAN, of 92 Sinclair Road, in the County of
Middlesex, Merchant, do hereby declare the nature of this invention to be as
follows :-
It has before been proposed to make extract of tea by evaporating an infusion of
the ordinary manufactured tea of commerce.
According to this invention the extract is prepared in the course of manufacture
in place of subsequently. The cells of the tea leaves are broken, the leaves are
pressed to extract the juice and the superfluous moisture is then evaporated from
such juice leaving the preparation which forms the subject of this invention.
The manufacture of the leaf may be carried on in any of the ordinary ways
omitting only the final drying or firing and substituting for it the pressure and
evaporation as above described but generally it is better in place of or in addition
to breaking the cells by rolling the withered leaf as is usually done to pass it
through a pair of rollers one roller being preferably driven faster than the other.
A vacuum pan is preferably used for extracting the moisture.
