Improvements in the Manufacture of Products from Tea.
I, JAMES DAVIDSON of 11 Waring Street, Belfast, Ireland, Tea Planter, do
hereby declare the nature of this invention to be as follows:-
My invention has reference to the manufacture of products from tea and
especially to the manufacture of tea extracts in liquid, pasty and dry form.
For the purpose of my invention I first make a strong infusion or decoction from
tea and this may be effected either by infusing tea with the smallest practicable
quantity of hot water or by submitting the tea to the action of steam in a closed
vessel. I then preferably subject the leaves to considerable pressure so as to
squeeze out as much liquid as possible. A strong infusion or decoction is thus
obtained. For the sake of economy I then preferably open out the compressed
leaves and make a further infusion or decoction therefrom in the same manner.
I next add to the infusion or decoction after evaporating it in order to bring it to
a sufficiently concentrated state, a preservative material preferably about an equal
weight of sugar and a small quantity of alcohol, borax, salicylic acid or the like.
The liquor is then boiled down to further concentrate it but leaving it still in a
liquid state, after which it may be bottled and kept for use or it is concentrated
still further to bring it to the form of paste or jam in which state it may be kept in
jars or pots, or it is yet further concentrated or dried to bring it to a solid form
either granulated or in cakes in which state it may be kept in bottles or other
receptacles.
The manner of employing the tea extract whether obtained in the liquid, pasty,
or solid form as hereinbefore described is simply to put a small quantity of it into a
pot and pour boiling water upon it. It is then ready for drinking and is in fact
the same as ordinary tea, sweet or otherwise according to the substance or substances
that have been mixed with it in order to preserve it.

be performed to be particularly described and ascertained in and by the following
statement:-

Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. The manufacture of products from tea by first making a strong iufusion or
decoction (preferably by squeezing as much liquid as possible from the infused or
decocted leaves) then concentrating the infusion or decoction, then adding a
preservative or preservatives thereto and then further concentrating it, this
concentration either leaving it in a still liquid state or in the form of paste or jam
or in a solid form as granules or cakes, the final product being put in bottles, jars
or other suitable receptacles, all substantially as set forth.
2. As new products, extracts of tea in liquid, pasty and dry form respectively,
obtained.substantially in the manner set forth.
