JOHN V. CANEPA AND PRIMIANO GASALENA, OF CHICAGO, ILLINOIS.

MACARONI-DRIER.

Specification of Letters Patent.

Patented Nov. 26, 1918.

Application filed November 3, 1917. Serial No. 200,038.

To all whom it may concern:

Be it known that we, JOHN V. CAnErA, a citizen of the United States, and PRIMIANO CASALENA, a subject of the King of Italy, both residing at Chicago, in the county'of Cook and State of Illinois, have invented certain new and. useful Improvements in Macaroni-Driers, of which the following is a specification.

This invention relates to a macaroni drier and has for its object the provision of an apparatus for circulating air through and about-a suitable. chamber in which macaroni is disposed for the purpose of removing the surplus moisture.

A further object of our invention is the provision of an apparatus of the character described which may be easily regulated to produce uniform drying regardless of the exterior atmospheric conditions.

A still "further ob ect of our invention is the provision of an apparatus through which,

the air flows with a minimum of resistance so that a fan of relatively low capacity requiring a small amount of power may be Another object of provision of an apparatus which is readily accessible so that the drying chamber may be quickly filled and discharged from time to time.

Further objects and. advantages of our invention reside in the various combinations as hereinafter described as will be better understood by reference to the following specification when read in connection with the accompanying drawing illustrating the preferred embodiment thereof, in which- Figure l is a longitudinal section through a drier according to our invention;

Fig. 2 is a transverse section through the drier;

Fig. 3 is a detail in elevation of one of the drying racks, and v Fig. 4 is a fragmentary detail in perspective illustrating the structure of the drying racks; v

Our improved drier comprises an outer shell having side walls 5, end walls 6 and a top 7. The walls are preferably double, as indicated in Figs. 1 and 2, inclosing air spaces which insulate the interior of the drier and prevent temperature changes bherein corresponding to changes 11]. the sur5 our invention is thev of the drier above the drying rounding atmosphere. Doors 8 and 9 in one of the side walls 5 adjacent the ends of the drier give access to the interior thereof. These doors may be otherwise disposed but are conveniently arranged as shown in the drawing. a

Within the outer shell above described we provide transverse partitions 10 and 11 extending across the chamber. These partitions consist of a plurality of shutters connected to louvers 12 and 13 which permit manipulation of the shutters to adjust the opening therebetween. A ceiling '14 extends across the chamber connecting upper edges of the partitions 10 and 11" and forming therewith an inner drying compartment to which access is obtained through doors 15.

afan 17 ing 21 to permit regulation of the passage f of air therethrough.

Steam pipes 23 are arranged-transversely;

compartment on either side of the fan 17. The top 7 of the drier is preferably in Fig. 1 in order that passage of air may be minimized. Thus a motor of relatively small capacity is sufficient to maintain circulation of air in the apparatus. Inlet openings 24. are provided in the end walls 6 of thedrier and are controlled by suitable doors'27 which are preferably arranged in three separate sections as curved as indicated the resistance to the indicated in Fig. 2 to permit air to be directed to different portions of compartment. v

The macaroni is supported in racks 28, Fig. 3 mounted on casters 29, the racks 28 preferably constructed of angle lIOIlSO-COII- the drying.-

nected by cross bars 31'having recesses 32 therein to receiveround bars 33 which are removably mounted in the. recesses and over which the macaroni is hung as soon as it is received from the press. The racks 28 are than wheeled into the drying compartment through the doors 15 which are'closed, after which the drying OPbidElOIl is continued without disturbing the racks by suitable regulation of the damper 22 and doors 27. The shutters in the partitions 10 and 11 may also be adjusted to control the flow of air which is caused by the rotation'of the fan 17. The speed of rotation of the fan may be adjusted at will by suitable regulating devices (not shown) for controlling the motor. When the damper 22 and doors 27 are closed, the air within the drier circulates through and about the drying compartment and is heated by the steam pipes 23. When the damper 22 and doors 27 are open the air is drawn between the shutters through the macaroni in the racks and is exhausted through the outlet opening 21.

From the foregoing description it will be apparent that we have perfected an apparatus embodying numerous novel features of construction which facilitate the handling and drying of macaroni which has been heretofore largely dried in trays. These trays are very bulky and require considerable handling as well as careful arrangement of the macaroni therein prior to the drying operation. Our invention makes it possible to materially shorten the time required for properly drying macaroni without producing a product in any way inferior to goods dried in apparatus heretofore in use. The air in my apparatus is so evenly distributed that the macaroni dries uniformly throughout the drying compartment and it is unnecessary therefore to shift the racks during the drying operation. Thus one of the inherent disadvantages of drying apparatus having forced circulation and usually provided with a fan at one end of the drying compartment, has been overcome in my apparatus through arrangement of the fan in the top of the drying compartment so that it draws the air from both ends thereof.

Various changes may be made in the form, construction and arrangement of the parts without departing from the spirit and scope of the invention or sacrificing any of its material advantages, the form hereinbefore described being merely the preferred embodiment thereof.
