J. 'F. LAFFOON WHEAT TREATING DEYICE Filed Ana. 5.
Patented June I9, 1924.
JAMES F. LAFYEOON, OF KANSAS CITY, MISSOURI.
Application filed August 5,
To all whom it may concern:
Be it known that I, JAMES F. IJAFFOON, a
had to the accompanying drawings, and to T i and a discharge 14. The grain may be fed the letters and figures of reference marked thereon, which form a part of this specification.
This invention relates to agrain tempering or conditioning tank, the primary object being to equally distribute the moisture throughout the grain stream as it passes from the inlet to the outlet, preparatory to being fed into the breaking rolls.
It is also an object'of the invention to permit uniform expansion of the individual grains during the tempering'process.
In carrying out my invention I provide a vertically arranged, elongated tank or tower in which the grain may be fed and allowed to gravitate toward the bottom in such a manner that there will be a rolling action of'the grains one upon another, the stream being sub-divided so that the sub-divided streams may expand and contract to efiect the rolling action and to allow the individual grains to expand due to the absorbed moisture.
One form of device constructed in accordance with my invention is illustrated in the accompanying drawings, in which Fig. I is a vertical, longitudinal, sectional view through a tank or tower with the stream-dividing devices therein.
Fig. II is a view partly in section and partly in perspective of the tank or tower and the stream dividing devices, and
Fig. III is a vertical, longitudinal, sectional view through one of the stream dividing devices and a portion of the wall of the tower.
The invention is illustrated as consisting of an elongated tubular tank or tower 1, preferably disposed vertically between two floors 2 and 3. vVit-hin the tubular tank or tower is a plurality of stream dividing devices, each of which consists of a support, illustrated as a disk 4, to which are secured a plurality of stream dividing hoppers or fun- 1920. Seria1N0.401,284.
nels 5, 6, 7 and 8, formed by dividing a main hopper into a plurality of compartments through the partition members designated 9 and 10.
The stream dividing devices are spacedapart to provide chambers 11, through which I the grain passes. The lower ends of the hop pers 5, 6, 7 and 8 are restrictechas at 12,
while the upper ends are relatively large, the combined hoppers being substantially the area of the tank or tower 1'.
The tower 1 is provided with an inlet 13f into the inlet in a moistened condition and pers where the stream lines will be divided into constricted subdivisions and as they pass through the discharge end 12, they will be permitted to expand as they seek'the line of repose, as indicated at 15...
As the subdivided streams of grain pass into the second chamber below the first set of stream-dividing devices, the grain will roll one over the other, equally distributing the moisture and reducing the pressure of the stream so that the grains may expand to a certain extent. The stream is then collected in the second set of hoppers and the same action is performed.
Any number of hoppers or groups of hop pers may be utilized to perform the desired result so that I do not wish to be limited to the particular arrangement or number shown.
If desired, the wall of the tower or tank may be provided with a baflied inlet opening 16 having an inwardly projecting wing or hook 17 to direct the grain away from the opening but which will allow the insertion of through the discharge spout 14 into thebreaking rolls, to be carried to any point desired.
It has been found in actual practice that a device constructed in accordance with the lilt) one just described will efficiently carry out the purpose for which it is intended; to wit: to allow the grain to pass through the tower in sub-divided streams which alternately contract and expand and which cause the grains to tumble one over the other as they pass through the tank or tower, the action being eifective in allowing thorough expansion of the grain so that pressure thereon is relieved.
I have found in actual practice that the,
best results are obtained by staggering the discharge ends 12 of the hoppers in one set with respect to the receiving ends of an adjacent set of hoppers. For example, if the discharge portions 12 of one set of hoppers arerin line with the partition members 10 of the next succeeding set of hoppers, the wheat will be caused to roll as it is delivered through the cylinder or tower and an efficient result will be obtained.
The container 1 is always full of grain and the wet grain is fed into the container 1 at the same rate that it is discharged from it. The movement through the container 1 is exceedingly slow so that tie grain. will have time to swell or expand as well as to have a slow rolling contact of the grains one upon the other. The device differs from an ordinary steaming or tempering device in that it treats the grain after it has been Steamed or initially tempered. It does not take the place of a tempering device but is for treating the grain after steaming or temperin 1,4.ee,see
What I claim and desire to secure by Letters-Patent is:
1. A. wheat treating device comprising a tower, and stream-dividing devices in spaced relation within the tower, each stream-dividing device having a receiving mouth coextensive with the interior of the tower and havinga plurality of inset, restricted outlets.
2. A wheat treating device comprising a tower, and stream-dividing devices in spaced relation within the tower, each stream-dividing device having a receiving month coextensive with the interior of the tower and having a plurality of inset, restricted outlets, the spaces between the strea1n-dividing devices being unobstructed, for the purpose set forth.
3. A wheat treating device comprising a tower, spaced supports dividing the interior of the tower into chambers, and stream-dividing devices located above each support, each comprising a partitioned hopper having a receiving month co-extensive with the interior of the tower and having a restricted outlet for each partitioned section, inset from the wall of the tower and projected through the underlying support.
In testimony whereof I aflix my signature.
