A Process for the Production of Sugar-colour from Brewery and
Distillery Refuse.
We, JULIUS MOSLER, Brewery Manager, Max SCHÄFFER, Manufacturer, and
ARTHUR SACHS, Manufacturer, all of 49 Delbrück Strasse, Rixdorf, near Berlin,
Germany, 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 :—
The disposal of brewery and distillery refuse, is, as is well known, very difficult,
as, when the refuse is allowed to run into ponds or rivers, the sanitary authorities
raise objections, and, when it is allowed to collect in pits, it has been found to
produce hurtful results, as the surrounding soil becomes more or less saturated, and,
as a consequence, any adjacent wells or springs are poisoned.
To overcome the difficulty, it was, at first, proposed to evaporate the refuse, but
this plan was not successfully carried out, on account of the enormous expense for
fuel and machinery.
The present invention is designed to solve the difficulty by extracting from the
refuse a useful and marketable commodity.
The method of extraction is as follows:-Refuse, such as spoiled beer, sediment
from casks, vats, etc., water which has been in use for rinsing purposes, and the
like, is conducted into a reservoir. From the reservoir, the refuse passes through
a suitable efflux opening into a so-called "filter range," that is, a series of filters.
The filters, which are, or may be, arranged one on top of the other, are filled with
cellulose, bone ashes, and burnt magnesia. After the liquor has passed through
the filters, it is conducted to one or more vacuum pans, and there evaporated. The
residuum remaining in the pans is taken out and caramelled in roasting pans.
With this procedure, the first part of the process is finished, the colour being
extracted from the raw material.
The colour is now mixed with water and boiled for some time, soda and milk of
lime being added during the boiling process. It is then filtered again, and
subsequently boiled with an addition of glycerine. During the boiling process,
the scum is continuously taken off the liquid. The boiling is continued until the
liquor has acquired a clear colour and consistency.
The proportions of soda, milk of lime, and glycerine used in the process
are:-say, to each hectolitre of refuse, 5 grammes milk of lime, (95 parts water
and 5 burnt lime), 2 grammes crystallized soda, and 2 grammes glycerine.
The advantage of the invention is obvious, as a waste product, which was
formerly considered both injurious and of no value, can now be utilized to produce
a valuable and marketable commodity.
The sugar colour is used for colouring liquids, such as beer &c.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :-
A process for producing sugar-colour from brewery and distillery refuse,
consisting in first passing the refuse, through filters, of cellulose, bone ash, and
burnt magnesia, then evaporating the moisture in vacuum pans, and caramelling the
residuum in roasting pans, thereafter mixing it with water and again boiling it,
soda and milk of lime being added during the boiling process, subsequently filtering

and consistency, substantially as hereinbefore set forth.
