To all whom z't may concern:

Be it known that I, JAMES H. BEEBEE, a citizen of the United States, residing at Rochester, in the county of Monroe and State of New York, havel invented a new and Improved Apparatus for Drying Moisture- Bearing Substances, of which the following is a specification. v

My invention, while relating to methods of and means for drying fruit, vegetables, lumber or other like moisture bearlng substances has more especial reference to devices for this purpose commonly known as air drying apparatus.

One of the objects of my present invention is to effect a thorough drying of substances such as above mentioned by placing them in an air tight inclosure and using the air within the inclosure repeatedly by keeping it in continuous circulation, the moisture absorbed from the fruit, vegetables or other substance being in turn removed from the air by directing the air currents over a suitable dehydrating material such as chlorid of calcium.

Another object of the invention is to provide an apparatus for accomplishing such rst named object that is simple, practical and inexpensive in construction and that can be built 1n various shapes and sizes according to the particular purpose for which it is to be used.

And still another object of the invention is the provision within a comparatively small compartment of a large area over which to spread the dehydrating material.

These and other objects of the invention pertaining more especially to details of construction will be clearly set forth in the following description and particularly defined in the appended claims.

The accompanying drawings illustrating the invention are as follows:

Figure 1 is a horizontal sectional view of the apparatus taken along the line 1 1 of Fig. 2;

Fig. 2 is a part side elevation and part vertical sectional view taken along the line 2 2 of Fig. 1;

Fig. 3 is an enlarged vertical sectional view of the extension chamber also taken along the line 2 2 of Fig. 1;

Fig. 4 is a transverse vertical sectional view taken along the line -1-4 of Fig. 3 but drawn to a smaller Scale;

And, Fig. 5 is a transverse vertical sectional detail taken along the line 5 5 of Fig. 3 but with the air distributing tube shown in full.

Similar reference numerals refer to similar parts throughout the several views.

The numeral 1 represents a dry kiln which may be of any desired size according to the use for which it is intended and constructed of any suitable material. This kiln may also be of any preferred conformation although the one shown in the drawings as embodying my invention is rectangular and provided with side walls 2 2, a front wall 3, a top 4, f

a base 5 and a rear wall 6 having a door-way 7 normally closed by a swinging door 8. Supported on the base 5 are a plurality of longitudinally extending ioists 9 which in turn support a flooring formed by transversely extending boards or slats 10 with spaces between them, these spaces gradually becoming wider toward the rear of the kiln or to the left with respect to Figs. 1 and 2. The floor thus formed has an a1r space beneath it and the boards being spaced farther apart toward the rear of the kiln permit a more equal distribution of the air currents as they are directed rearwardly between the several joists in the manner to be explained.

On the front of the kiln and preferably in the center thereof is an extension 11 provided with side and front walls and a rearwardly vinclined top wall 12. This extension forms a chamber having communication with the kiln proper through an opening 13 in the upper portion of the front wall 3. Supported longitudinally within this extension just below the opening 13 is a perforated plate 14, while below the plate there are slidably and removably supported a plurality of trays or pans 15 arranged in staggered relation relative their side edges, see Fig. 4.

These trays are supported upon

angle bars

16 and 17, the bars 16 being secured to the. side walls of the extension chamber 11 while the bars 17 are carried by brackets 18 secured to such side walls.

The trays 15 comprise receptacles for containing the moisture absorbing substance and by having a number of them there is provided, within a comparatively small compartment, a large area over which to spread this substance. rIhey are also preferably supported on a slight incline and have perforations 34 along their lower edges permitting the substance, when such as chlorid of calcium is used, to be drained from one an to another as it gradually becomes lique ed by the moisture absorbed through thc air from the fruit, vegetables or other material being dried in the kiln. The front wall of the extension 11 is provided with an opening 19 for permitting removal of the several trays 15 but which is normally closed by a swinging door 20.

Removably supported on arms 21 secured to one of the side walls of the extension 11 is a receptacle 22 adapted to receive the liquid as it drops from the low'ermost tray 15, and the contents of this receptacle are drained through a pipe connection 23 eX- tending through the front wall of the eX- tension chamber and lprovided with a stop valve. 24. When the contents of the receptacle 22 has been drawn o' into another receptacle, not shown, the latter can be placed on a stove and the water evaporated so that the material can be again placed in thev trays for further use. The pipe connection 23 has a coupling 25 which when disconnecte ed permits a removal of the receptacle 22 through the opening 19.

Extending transversely of the kiln at the forward end of the joists 9 and housed in a suitable casing 26 is an air distributing head comprising a tube 27 closed at its ends and having a number of alined apertures 28 for directing the air rearwardly betweeny the several joists and under the floor boards 10,

the apertures toward the end of the tube preferably being somewhat larger than those near the center for the purpose of obtaining a more equal distribution of the air. The tube 27 opens at its center into an enlarged lateral extension 29 at the forward end of which is a fan 30 supported on the shaft 31 of an electric motor 32 mounted upon a standard 33 secured to the base 5. This fan creates a continuous circulation of the same air over and over again by drawing it from the-bottom of the 'extension chamber 11 and forcing it through the openings 28 in the distributing head 27 to the space beneath the ooring from whence it rises throughkthe spaces between the Hoor boards 10, circulates through the kiln, passes through the opening 13 into the upper part of the extension chamber 11, then downwardly through the perforated plate 14 and back and forth in the direction of the arrows Z, Fig. 4, over the several trays l5 containing the dehydrating material and againA into the distributing head 27.

It will thus be seen that the contents of the kiln are dried by usin the same air continuously and that the moisture absorbed byi the air from the fruit, vegetablesv or other substances is removed therefrom by the dehydrating material as the air passes over the trays 15 and that the air is in a dry Vstate when drawn by the fan into the distributing head 27. lt will also be seen that as the dehydrating material becomes liquefied it can` be drawn oii and the material reclaimed forI further use when the moisture has been.
