RACK-EVAPORATOR.

To all whom 'it may concern.'

Be it known that I, FRANoIs'WILLIAMs e a subject of the King of Great Britain and Ireland, residing at C.' B. S; Building, 9() King William street, Adelaide, State of South Australia, Commonwealth of; Australia, have invented a certain new and useful Improved Rack-Evaporator, (for which I have obtained a patent in Australia, No. 14,235, Feb. 3, 1920,) of which the following isa specification.` Y

This invention relates to an improved` evaporator, ofthe type known as rack evaporators, and it has been specially devised in order to provide an evaporator with which the dryingprocess may be .eifectively and expeditiously .completed in one building. And further, although this improved rack yevaporator has been particularly devised it may be readily adapted for' drying fruits,

; to treatother materials such as, for instance,

` timber, skins,

. the evaporator chamber fibrous sheetsV and bricks. This-improved rack evaporator comprises, preparing room, :sulfur a wilting-ro'om and an evaporator chamber all arranged within a building'of :special construction, a set or sets ofcracks also of special construction adapted to be' traveled throughy vthe several rooms and chambers, and supports for such racks. y The building has a cover 4or roof that is'v supported upon posts arranged inV transverse pairsin rows longitudinally ofthe building. There is asetor tier of'racks between each row of pairs of posts, and each post carries a number of rollers,`oneA for each rack, upon which the racks maybe traveled. c

Each rack has a frame comprising longitudinal side members, of wood or metal, connected by transverse members at convenient intervals corresponding withY the width of and reinforced by longitudinal and'diagonal wires. The frame is covered with netting. or hessian, or wood to support the materials' tobe dried.

' The racks `may be of any convenient length ;l there may be'any number ofy racks ina set or tier and any ,number of sets of racks may be usedl according 50,

more readilylcarried into practical etlj'ect ity to the quan `tity'ofmaterial to .-be treated. f But in order that theinvention may be "are outwardly of the wilting Specification of Letters Iiatent. Patented Aug, 16, 1921. Applica/cin lea'rebruary 25, 1921. serial No. 447,871. I y

will now be described with reference to they 4 is a plan of a rack frame partly Y covered with netting.

vations respectively showing portions ofone construction of. racks, and their supports while c Figs. 7 and 8 are similar vviews of a modiication of. such construction.

.Fig 9 is"a transverse section of a rack with wooden longitudinals.,

Fig. .10 is a detail view showing the method of joining thev sections of metal longitudinals ofthe rack; c A Y f The evaporating chamber and the wilting roomY aresituate'd side by side medially longitudinally of the building and extend from the Vfront tothe back thereof;the preparing room -1 is outwardlyof the, evaporating chamber 2, and the sulfuring chambers 3 room'l The :supporting 'posts 5 may be of'wood or metalv and theyare'arranged lin transverse pairs in rows longitudinally ofthe buildingg There is sufficient room between each of the posts cfa pair to-accommodate a set or tier of racks 6 while there issuliicient: room be tween each to be readily loaded and cleared.` l

Each rack.6 is supportedl on .wheels or rollers 7 arranged in opposed pairs on" the pairs of posts 5. These wheels are preferably flanged as at 8 and they arev carried'on pins 9 protruding from brackets 10 that `are secured to the posts 5 by bolts 11.V The 'racks maybeof any desired length. f f

Each rack has a frame comprising longitudinal lmembers. 12' extending the"r full length of the rackand transverse members 13, secured thereto at regular? intervals. Lon- `gitudinalv stay` wires 14 and diagonal vwires l5 complete Tand reinforce the frame.4

vThe side members 12 may be `of wood Figs. 5 and` 6 arevdetail end andside ele-'Z pair of rows to enable the racks shown in Figs. 5,6 and 9 vor they may `be ofg.-

metal piping as shown in Figs. 7 and 8. In the latter construction the sections of piping 16 are joined together by screw threaded plugs 17 Vso that the pipes present a continuous surface to the supporting rollers '2'.

traveled longitudinally of the building tliroughfthe various Y rooms and compartments Vby suitable mechanism, not shown in Y the drawings.

When treating vine fruits or'berries on f racks covered With netting the bottom rack ,l gmanner.

Awill befsupported 1.a convenient distance from the floor lto spermit the insertion of a.

tray or trays to catch anyl berries that may @fall from the racks.

When it is desiredwtotreat materials or products kother than fruit the-distance bei .f-tween the racksvvi-ll be varied` according to the material to beetieated; and itmav be-A advisable, in some cases, to substitute Lvvheeled trucks` supported .onrails for the racks and rollers.

.The evaporating chamber?J and the Wilting room 4 mavbeheatedin any convenient 2O underthe forwardpart of the chamber 2, the gases from which furnace `pass through -flues 21'and 22 to *sets* of'vertical tubes or pipes 23 in the chamberQ; andthe roomV 4; f

The sulfur chambers 3 have .pits 28 in Which sulfur is .burned the fumes `being directed therefrom .finto the chambers.

The preparing room is also the clearing off room, and the sweating Y floor or bins 32 complete the plant.

Itis to be understood that the Wilting g the fruit prior to passing it into the' evaporating chamber.

VIn-:describing the carrying of the invention into effect it Will be described as with a single raclrsinceV each rack lmay beeperated yindependently` but the "number of -racks in a set lor tier and the number of sets of racks will be as required. i

AIn operationr the empty rack 6 is kdrawn intothevpreparing room'l and= loaded With fruit. It is tlienfpassedthrough-the evapo- 85 rating cliamber/Qfand `the Wilting'room 4 into` thefsuliring chamber 3.

1f the Jfruit is to be sullured-the doors at the ends of the chambers''are closed and the necessary quantity ofsulfur -burnt Withinthe -pits 28,:the' fumes y.therefrom passing into" the sulfuring -chamber 3'.

jAfter this treatment thefrackY 6 is drawn -backfand its first section Ipositioned Within tion `beingx Within the ivilting room 4.

Afterthe fruit upon the section Within the evaporating chamber '2' has -been 'dried sufficiently the-rack 6 isl again moved the first section beingl'moved into the kcleaning off roomiandzthel-section `Which kWas previ- :ously 4inthe wilting room 4 being moved Yinto the evapora-ting chamber 2, a third; section being f moved intok the Wiltingroom.

lAfter treatment of @the second lsection Within the evaporating chamberafthe rack 6 is again moved lbringing other sections into the evaporatine;` chamber 2 and the Wilting'rooin 4.,-.and this vprocess is continued untilfthe Whole llength ofvv the :rack has lpassed 'into and through the -evaporating chamber 2 :and the `treatedv fruit hasbeen i removed.

,The rack is again-loadedxvithrfreslilfruit, passed backzthroughthe evaporating chamber and -Wilting room f into the sulturing chamber and the operationis repeated.

A'Pri'ortoand after -eachmovement of the jrackl6 the various curtains ordoors along thexsidesffof the xevaporating room 2 are 120 opened and y closed lt0 permit of such vmove- /ment WhatfI claim isz-'- 1.

each. of which comprises two side bars of either metal or wood, running the full length of the rack, transverse pieces fastened thereto at intervals forming sections, longitudinal and diagonal straining wires, and a covering of foraminous material.

7.V In an evaporator a number of racks each of which comprises two side bars made up of lengths of metal pipe joined together by screw threaded plugs, cross pieces fastened to the said side bars at intervals dividing the rack into sections, each of which sections is provided with stout straining wires and with aV suitable covering.

8. In an evaporator having a number of racks each of which comprises longitudinal members, Vtransverse members secured theresoL to at intervals, longitudinal and diagonal k straining wires and a covering or floor, slats secured to the Hoor of each rack at intervals corresponding to the transverse members and iieXible strips secured to the edge of each slat adapted to contact with the transversemembers of the rack next above in the set or tier. f
