APPARATUS FOR TREATING GRAIN.
Specification of Letters Patent.
Patented July 18, 1911.
Application filed November 7, 1910. Serial No. 591,137.
To all whom it may concern:
Be it known that I, ROBERT E. L. GRUBBS, a citizen of the United States, residing at San Joaquin, No. 1 Camaguey, Cuba, have invented new and useful Improvements in Apparatus for Treating Grain, of which the following is a specification.
This invention refers to improvements in apparatus for treating grain, especially cereal farina and fecula grains for the purposes of desiccating the same with a view of removing a portion of the moisture there' from. This feature of the invention also has for its object the destruction of such germs and bacilli, of a pathological nature, as may be destroyed by the degrees of temperature to which the grain is subjected in drying the same. The heat applied to the grain also has for its object the destruction of all insects, among the most prevalent of which is weevil and similar insects which propagate in stored grain.
The invention has for its object the provision of a furnace constructed with a revo luble body therein and the apparatus is so designed and arranged that the process of treating the grain may continue without interruption.
The invention has for its object a feature of novelty which will be more fully described in connection with the accompanying drawing and which will be more particularly pointed out and ascertained in and by the appended claims.
In the drawingFigure 1 is a longitudinal sectional view of an apparatus embodying the main features of my invention. Fig. 2 is an end elevation looking toward the feed end of the apparatus. Fig. 3 is a sectional view of line 33 of Fig. 1. Fig. 4 is a sectional view of the feed end with the feed hopper removed. Fig. 5 is a perspec tive detailed view of one of the parts of the apparatus.
Like numerals of reference designate like parts throughout the different figures of the drawing.
The apparatus shown includes a heating chamber or furnace designated at 1 and provided with a fire box 2 and a grate 3. A fuel door 4 is shown mounted in guides 5 and an outlet or stack 6 is provided, as shown. One
end of the furnace 1 is divided by a partigion 7 to provide a suitable discharge cham- 'Within the furnace 1 there is provided a revolubly mounted body preferably in the form of a cylinder 9 which is provided with an open end 10 which projects through the partition 7 and forms the outlet or discharge end for the grain. The cylinder 9 may be provided with a bearing ring 11 which, in cross section, is in the form of an angle with one flange overlapping the inner face of the partition 7. At its opposite end said cylinder 9 is provided with an end wall 12 having a tubular extension or bearing portion 13 adapted to be journaled in the wall 14 of the furnace. To this end the wall 14 is provided with a semi-circular bearing portion 15 having an upwardly projecting flange 16.
The tubular extension 13 is hollow and is adapted to form the intake end for the cylinder 9. V
A feed hopper 17 may be secured by any suitable means, such as a bolt 18, to the furnace 1, and is provided with a cylindrical extension 19 which feeds into the tubular struction is particularly advantageous in an apparatus of this character because it perinits of a centrally or axially free entrance of the grain or material and the latter during such feed does not in any way engage the operating shaft or bearing portions. It will also be seen that the outlet 10 affords a free and unrestricted opening for the discharge of material.
The revolving body or cylinder 9 is provided with means for moving and longitudinally advancing the grain therein during rotation of said body and said means is so constructed and arranged that in the act of discharging the material the same is advanced longitudinally of said body. As shown, said means comprises strips of metal 27 which are longitudinallv and spirally disposed in said cylinder 9 and which, in the form shown, extend from the intake to the discharge end thereof. Said strips are also shown having a spiral disposition of less than a complete circle so that the same do not intersect each other. The margins of said strips, as shown in Fig. 5, are slitted and bent forwardly in a direction generally parallel with the longitudinal axis of the cylinder 9 or the direction in which the ma terial therein is advanced, said forwardly bent portions being indicated at 28. It will be seen by reference to Fig. that the bent portions or projections 98 are also disposed at a slight angle with respect to the longitudinal axis of said cylinder 9, thereby providing forwardly inclined pockets into which the material falls and is lifted as the cylinder 9 rotates. These forwardly inclined pockets serve to discharge the material in a forward direction and thereby act to advance the material when so discharged. It will be readily seen that when the cylinder 9 is rotating the material will be continually caught in said pockets and discharged therefrom, so that the material will continually be changed in position with respect to the cylinder 9 and continually ad anced therein from the intake for the discharge end. lVhile the material is being subjected to this stirring action it is sul jected to the products of combustion from the tire-box to a temperature which approximates 212 F, a temperature suflicient to destroy or at least practically destroy any germs and. to wholly destroy any insects. During the passage of the grain through the body 9 the process of desiccation will be completed and the grain will be discharged into the chamber 8.
In the chamber 8 an inclined wall 29 directs the discharged grain to a chute 30. T he inclined wall 29 may be provided with perforations through which the refuse may descend into a lower chamber 31. A door may be provided for removing the dross which collects in the chamber 31 and a pivot flap 33 may be provided for the chamber 8, to control, or if desired, to wholly cut off the discharge of steam resulting from the drying of the grain.
I claim 1. An apparatus for treating grain comprising in combination, a revoluble receptacle for receiving the grain, strips disposed spirally in said receptacle and throughout less than a complete circle therein, said strips having teeth or projections thereon extending forwardly in the path of travel of the grain to engage and advance the grain when discharged therefrom, and means for heating the grain in said recelr tacle.
