UNHTED STATES PATENT OFF-ICE.

MAX F. MANGELSDORFE'OF UNION HILL, NEW JERSEY.

DRYING-MACHINE.

F. IVTANGELS- States, res1d Hudson, and

State of New Jersey, have invented certain new and useful improvements in Drying- Idachines, of which the following is'a full,

clear, and exact specification.

My invent-ion relates to drying machines and refers particularly to machines adapted to the drying of products liable to adhere to each other.

One object of my invention is a device in which the products are intermittently interiningling during the drying process.

Another object of my invention is device in which the drying material is allowed to fall from one tray to another in the direction of the incoming drying air.

Another object of my invention is a device designed to prevent the drying particles from adhering to each. other during the drying process. I

Another object of my invention is a device in which the material to be dried is spread in a practically uniform layer over each dry-- in tray.

Another object of my invention is a device in which the material to be dried is mixed and thoroughly submitted to the drying action of a flow of drying gas or air.

These and other objects of my invention will be evident upon a consideration of my specification, drawings and claims.

My device is suitable for the drying of any material particles, but is especially adapted for the drying of those materials, which have a tendency to adhere during the drying process, such assliced vegetables. fruits, etc.

In order to prevent the above mentioned adherence, it is essential that the particles be subjected to a gradual increase of heat, that there be an intermingling of the parti cles during the process and that the layers be of a uniform thickness of not too great a depth.

If the material be subjected at once to a high heat, the particles will adhere due to their starchy or glutinous contents becoming dry while the various particles are in abutment with each other. It is evident therefore that the particle mass must be heated gradually while being subjected to suflicient Specification of Letters Patent. Patented Oct 12, 192() filed September 14, 1918. Serial No. 254,061. l l

agitation to prevent their'complete drying while in an excessively wet condition. It is further evident that if the layers are too thick, or uneven, the weight of the material will cause the lower portions to adhere.

The device of my invention overcomes all of these difficulties and presents a means whereby material of the described character may be completely dried without the adherence of the particles to each other. 7 In the accompanying drawings, illustratln'g one form of my device, similar parts are designated by similar numerals:

Figure l is a vertical cross-section of one form of mydevice. I

Fig. 2 is'a broken section through the line 22 of Fig. 1. I

Fig. 3 is a section through the line 3-3 of Fig. 1.

Fig. 4 is a section through the line 4 -41: of Fig. 5. r

Fig. 5 is a section through the line 5-5 of Fig.

Fig. 6 is a broken section through the line 6-6 of Fig. 1.

The particular form of my device shown in the accompanying drawings comprises a drying box having the

sides

20, 21, 22 and 23, the top 2 1 and the inclined bottom 25. The top 24 carries a hopper 26 at one end thereof and a centrally located stack 27. Within the drying box are two series of spaced parallel traysA and B, each tray being composed of a series of revoluble plates, the axis of rotation of each series of platesbeing at right angles to the axis of rotation of the revoluble plates of the adjacent tray. The hopper 26 containsv a series of downwardly converging distributing

plates

28, 28.

In the upper portion of the drying box, a shaft 29 extends between the

sides

20 and 22 and is revoluble therein. The shaft 29 carries the sprocket wheel 30 at each end thereof. Within the other side of the drying box and in alinement with the shaft 29 is the shaft 31, revoluble within the

sides

20 and 22, carrying a sprocket wheel 32 at each end thereof. The shaft 31 also carries the sprocket wheel 83. Meshing with the revoluble shaft 37, by meansv of the chain belt 38. Revoluble upon the shaft 37 is a sprocket wheel 39, which is connected by the chain belt 40 withthe sprocket idler 41 carried by the shaft a2. A miter gear a3 is inf 'tegral with the sprocket 39 and meshes with the miter gear 43 revoluble upon the shaft 44. Integral with the miter gear 43 is-the sprocket wheel e5, connected by means of the endless chain belt 46 with the sprocket wheel 4:8 fixedly attachedto the revoluble shaft l9. The shaft 49 carries the fixedly attached gear wheel 50, meshing with the worm 51,

V which, in turn, is connected to a source of revoluble power. A revolub'le "shaft 52 carried by the

walls

21 and 23, has the sprocket wheels 53 and 54: fixedly attached. thereto. The sprocket 542 is connected to the sprocket 55 fixedly attached to the shaft 5L9 by means of the endlesschain conveyer 56'having a series of outwardly

extended partition plates

57, 57. The sprocket 53 is connected by means of a chain'belt 58-to the sprocket 59 fixedly attached to the. revoluble shaft 60, the shaft 60' carrying a series of fixedly attached outwardly extended discharging otally attached to the connecting arm .at 71, 71.

Each connecting ar 1. T0 is pivotally connected at 72' to an arm 73 'ilxedly attached to the rovoluble shaft 74 which also carries the gear wheel 75. necting arm 67 is pivotally connected at 7 6 to the arm fixedly attached to the 'revoluble shaft '78 which also carries the gear wheel '79. The chain belt 40 carries the gear racks. 80; 80 ca able of meshing with the gearv wheels 79, 4'9 and giving them a half revolution. The chain belt 46 carries the two gear raclrs 8l, 81 capable of meshing with the

gear wheels

75, 7 5 and giving them a half revolution.

A pipe 82 connected with the-drying ch amber allowsthe introduction of hot air into the dryin the stackZ'Z. V

The operation of the device lS'.E1S fOllows V A revoluble movement is given the shaft t9 by means of the gear wheel-50 and the worm The sprocket wheel 48.. attached to'the shaft 49, revolves the chain belt @6 with the

racks

81, 81" over the sprocket wheel A to fall upon tray v Each con chamber, the air escaping through 4:5. During this movement of the chain belt 16, the '

acks

81, 81 mesh with the gear wheels 75, giving them a semi-revolution, which, in turn, revolves the arms "[3, 7 3, moving the connecting

rods

70, 70, revolving the shafts 65, 65' by means of the

crank arms

69, 69. Each movement of a shaft 65 causes the leaves 6e, 64; to revolve first into an abutting position forming a tray 15 and then into parallel positlons allowing the contents of a tray B to fall upon the tray A immediately beneath. "he sprocket wheel 45 and the miterzgear e3 revolve on the shaft 4A, the miter gear 43. meshing with the miter gear 43 revolving the shaft 37, over the idler sprocket t1. During this movement of the chain belt 4:0, the racks 80, mesh with the gear wheels 79, T9, giving them a semi-revolution, which,in turn,

revolves the arms '77, moving the connecting

rods

67, 67, revolving the

shafts

63, 63 by means of the

crank arms

66, 66. Each movement of a shaft 63 causes the

leaves

62,, 62 to revolve first into an abutting position forming a tray A and then into parallel positions allowing the'contents of a tray the tray 13 immediately beneath.

The racks 80,f80"and 81, Si are so poSi' tioned that their movement will first revolve the lowest tray delivering the contents downwardly, then revolving the next tray above delivering'its contents upon the empty tray beneathythis operation being repeated upwardly. The rapidity of the movementof the chains l0 and a6, carrying the racks will time the rapidity of this delivering movement.

The revolution of the shaft 3? will re volve the sprocket 36, the chain 38, the sprocket 33, the shaft 1, the sprocket 32 and thus move the chain with the distributing

plates

35, 35;

The revolution of the shaft 4 9, resolves the sprocket wheel 55, the conveyer chain 56, thesprocket wheel 54;. the shaft 52, the sprocket wheel 53', the chain 58, the sprocket wheel 59, the shaft 60 and the discharging

plates

61, 61.

'From the above it will be seen thatjthe operation of the demos, considering all the trays filled with material to be dried, is as follows g V Theleaves of the lowest tray are revolved d scharging the contents upon the 'chain conveyer which deposits them into the dis charge chute 100, whence they are d'eliv-' ered by the delivering plates. The next to the bottom tray is then revolved and the contents deposited upon the lowest tray. this operation being continuously repeated upwardly.

During the drying operation the material is introduced through'the hopper26 and distributed by the plates 28, uponthe chain conveyor 34:, :which deposits it upon the uppertray, the

plates

35, 35 spreading the material into practically a uniform layer.

Air of the requisite'temperature is intro duced through the pipe 82. 1

As the leaves of each tray are revolu is at right angles to those of the tray beneath, it'is evident that the material will be thoroughly commingled and that the layers will be of approximate thickness. I' do not limit myself to the particular size, shape, number or arrangement of parts as described and shown, all of which may be varied without going beyond the scope of my invention as described and claimed.
