A vacuulll puiiip or o er stiction mtcliine 78, the power for -which 20 naay be fitrnished from the boilers @7, is also placed in the building 57 ,tnd connected by iiieans of a duct 60, to the -Lipper p,,trt of the coiiipartment 46, so ,is to exhaust the ai@ and withdraw the moistilre from the said com.. 25 partment. This drier may be suppliecl with flues siieh as shown at 35 and 3,5a in Figs. 3 -ind 4, if desired, to di tribute the h ated air s e uniformly throuo,,h the mass of grain in the compartment 46. 30 To provide access to the comp,,trtment 46 ' there is ,tn opening 61, placed at a distance above the floor 45, ,tnd normally closed tigli@ by I me,,tus of the door 62, and there are insidc. and o-Litside laclders 63 and 64:, reST)ectii,ely, 35 to proi7ide ,teaess to the sqid opening. -The grain elevator 65, previously refei@red tol wbich Supplies the grain to the drier h,,is the drag or hopper 66, at the, lower end adapted to bave the grain supplied directly 40 tbereto from the w,,tgon or othei-wise sup]?lied if desired. For taking the gr,,tin fi-om the drier there is an opening or (loorwty 67, from@ the lower cornpartment 47, wbiel@ I's iiorm,@illy closed 45 tight'by means of a cloor 68, and communicates -,vith an qrea 6(,), throuo@h which access is hid to the compartment 47. A. conveyer or drag l'O, which may nol-mally I)e coiitained in the compartiiient 47, as shown it 50 70 in Fig. 13, is arranged directly below the openino, 46 tlirou(,Yh the floor 45, so ,is to receive the, 9,,rain as it falls thro-Llo-,Ii t.he o-Denini:,:. TI-iis coni,eyer m,,ty be prole,,tod throu(,,h the opening'67, as shown b . @ the 55 dotted lines in Fig. 13, and connected with suit,ible driving machinery so as to c,,trry the grain to the exterior of the compartment 4'@. A bin or gr,,,tn,,,try 71, for final stor,,ige of the or,,tin, may be located conveniently 60 near th@ drier 37,'and tbe, conveyer 70, m,,ty be, arran-aed to disebtroe into t@@ lower end of the elev,,ttor 72, t-be Tipper end of which disebarges into the top of the bin or granary. 71. I have shown the complete outfit of Figs. 65 11 and 12, in connection with the drier 38, but it is to be understood, thit the drier, shown in Fios. 1 to 9 may be Lised in place of the drier 38 and furthermore either of these driers may be used witho-Lii the finltl 70 storage bin as shown in Fig@. 11 and 12, without departing from the spirit-of MY vention'. The operation is as follows: @Ass iiiino, th,,Lt we have the complete equip- 75 inciit Q-h6wn i.@-i Filo,@s. II and 12,-a, wtgon I.o,,tded Niith the grain to be dried, will be duml)ecl into the - dracy or hopper 66,, or will be, otlier-@ise stipi:)Iied and c,%rried by means of the elevator 65 to the top of the 50 gi@,tin drier ,tnd discharg@d into the upper artm comp ent of the drier. The suction mechaiiism aiid heating plant will then bb oper,,tted and air will be supplied and reguItited so as to maintain a pressure @below at- 85 liaospheric in the drier to withdraw the moisture from the gr,,tin. After the grain is tlioro,tighly dried, the valves in the bottom of the upper compartment of the drier are opened and the grain which fa.11s there.. 90 through is carried by the conveyer TO and the elevator 72, to the final storaole bin 71) or may be otherwise disposed o . In the driers shown in Figs. 1 to 9, inclusive, the hot air is supplied directly by the heating 95 plant, and the ventilation of the drier is controlled by feculatiiig the opening of the inlet ducts 12, wl@ich supply air to be heated by the furn,,tees. The ,tctioii of the drier in Fius. 11 to 17, 100 inclusive, is similar to, that of the preceding figures, except tl-i,,tt the heating element consi@ts of a coil and there are air inlets lelding directly into the lower compartmeiit and passing tl-irouga the coil 54, to tlie Lipper 105 con-il:)artnient 46. In the clryijig operttion I have found that the best restilts are obtained, particul',Irly ivith etr corn by first heating the mass of corn in the compartmeiit to a hioh tempera- 110 ture after which the suction Dfechanism is set ii-i opei,ation -aiid the temperature allowed to diminish somewhat while the, air is eirelilqted through the grain. While I have herein referred to this drier 111 as being used in connection with the drying of grain, I do not limit its use theret@ bu't coiitemplate using it for dryin-a or treatino, any i-iiaterial, and I am also aware that various details of constrluction may be varied 120 tl-irotigh ,t wide range without departing -from the principles of this invention@ I therefore do not purpose limiting the patent granted otherwise than iiecessitated@ by the prior ait. 125 I
