PROVISIONAL SPECIFICATION.
An Improvement in the Preparation of Gelatinized Grain.
We, JAMES DEATH of No. 7 Oakley. Crescont St. Lukes in the County of Middlesex,
Consulting Brewer and ALFRED SAVILL TOMKINS of 61 Mark Lane in the City of
London Malt Factor do hereby declare the nature of this invention to be as
follows:
Our invention relates to the preparation of gelatinized grain such as is frequently
used in brewing, distilling, and vinegar making.
In preparing such gelatinized grain, which is to be subsequently dried, it has been
usual to pass steam into cold moist grain, but in this case, owing to the primary con-
densation of the steam, a porridge or agglutination is often formed, so that the grain,
after being more or less gelatinized, is difficult to dry and portions of it are wasted.
According to our invention we first moisten the grain and then heat the moistened
grain in any known manner; a convenient means being to subject it to a current of
hot air, which may be moist.
Into the moist grain thus heated we pass steam at atmospheric pressure until
sufficient gelatinization has been effected.
The steam may be superheated and it may be passed into the hot moist grain either
continuously or intermittently and may be alternated with currents of hot moist air.
After gelatinization the grain may be dried in any known manner.
Dated this 8th day of September 1887.

An Improvement in the Preparation of Gelatinized Grain.
We, JAMES DEATH, of No. 7 Oakley Crescent, St. Lukes, in the County of Middlesex,
Consulting Brewer, and ALFRED SAVILL TOMKINS, of 61 Mark Lane, in the City of
London, Malt Factor, 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 :-
Our invention relates to the preparation of gelatinized grain such as is frequently
used in brewing, distilling, and vinegar making.
In preparing such gelatinized grain which is to be subsequently dried, it has been
usual to pass steam into cold moist grain but in this case owing to the primary con-
densation of the steam a porridge or agglutination is often formed so that the grain
after being more or less gelatinized is difficult to dry and portions of it are wasted.
According to our invention we first moisten the grain and then heat the moistened
grain in any known manner a convenient means being to subject it to a current of hot
air which may be moist.
Into the moist grain thus heated we pass steam at atmospheric pressure until
sufficient gelatinization has been effected. The steam may be superheated and it may
be passed into the hot moist grain either continuously or intermittently and may be
alternated with currents of hot moist air. After gelatinization the grain may be dried
in any known manner.
A convenient mode of subjecting the grain to the above described action and
carrying on the operation uniformly and continuously is to cause the grain to travel
along troughs with heated casings or arranged in a heated kiln by means of screw
conveyors.
These screw conveyors may have tubular axes along which steam is conducted to
issue from them in jets by lateral perforations. The first part of the screw conveyor
where the grain is fed in may have no perforations the grain being thus slightly
heated before being steamed. Also the latter part of the screw conveyer may be
without perforations for the steain so that the grain may be dried after gelatinization.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
--
The herein described process for preparation of gelatinized grain by heating and
steaming moistened grain and then drying the gelatinized product.
