FRUIT-DRIER.

SPECIFICATION forming part of Letters Patent No. 572,224, dated December 1, 1896. Application filed November 22, 1895. Serial No. 569,818. (No model.)

To a/ZZ whom t myconcern.-

Be it known that I, ARTHUR B. SHEARER, a citizen of the United States, residing at Arroyo Grande, in the county of Sau Luis Obispo and State of Oalifornia, have invented certain new and useful Improvements in Fruit- Driers, of which the following specification contains a full, clear, and exact description,

' reference being had to the accompanying drawings, in which- Figure l is a sectional View of my improved drier, parts of the construction being shown in elevation. Fig. 2 is a plan view of same, parts being broken away and others in section.

A represents a suitable building, within which the drying-chamber Al is located. In two corners of the said building A are constructed the sulfur-room A2 and the storeroom A3, while between the sides of the drying-chamber and the ends of the building are located the storm-room A4 andthe examination-room A5, respectively. The door-openings a a at the sides of the drying-chamber A' are provided with swinging doors o a', which close communication between the storm and examination rooms, and the storm-room has similar doors at at its end, while the examination-room has such doors a5 in its side. The store-room is provided with swinging doors a3, which close communication with the examination-room A5, and the sulfur-room A2 has similar doors a2, which close communication with that portion of the building A. Longitudinal tracks B extend through the storm-room, drying-chamber, and examination-room A5,where a turn-table B is provided, a similar turntable B2 being provided at the opposite ends of the tracks between the side of the main building and the doors o4 of the storm-room. The two turn-tables B B2 are connected by a track B3, exterior to the drying-chamber, and this track also leads into the sulfur-room A2. This system of tracks and turn-tables enables the cars containing the fruit to be readily shifted from place to place or room to room, as may be desired. The turn-table B2 comes opposite the door A6 of the building A.

The drying-chamber A at one side of the tracks B is formed as a circular casing C, which is open at its side next to the tracks, and within this casing is the large fan-wheel C', the shaft of which, exterior to the said Within the chamber A7, behind the glassplate or partition, are the sprayers D', which spray cold water on the upper end of the condenser-plate to constantly cool it, and this action is supplemented by a fan D2, which forces cold air against the plate and descending stream of water. It will be seen, therefore, that the blast of hot air from the fan C will, after passing the fruit, strike the condenser D and deposit thereon any moisture absorbed from the fruit. The moisture thus deposited will run down the condenser D and be carried away by the trough or gutter d. The chamber A7 has an opening a7, connected with a ventilator di in the top of the main building. The water running down the inner side of the condenser D will be carried oif by gutter d.

In the upper part of the building is a chamber AS, having an opening as adjacent to the glass condenser D, and within the vchamber A8 is a steel pressure-blower E, which draws the air up from the drying-chamber past the glass condenser D and forces it down through a pipe e to the bottom of the furnace or heater F, from the top of which it is drawn through the pipes fback to the fan-casing C to be again discharged across the trays of fruit.

The furnace or heater F is arranged below the floor-line, as shown in the drawings, and may be formed of any old -worn-out steamboiler, the water and steam space being used for heating the air. This reuse of the heated air will effect a considerable saving of fuel, as less heat is required than would be necessary if the heater was supplied with cold air.

The drying-chamber will be constantly s upplied with thoroughly dried heated air and the drying of the fruit will be efficiently and expeditiously effected, and that by very simple and inexpensive means.

The fans C D2 and blower E are driven from the engine G by suitable shafting and belting, the engine being located in the building A between the storm and sulfur rooms.

IAI represents a car provided with a hori- IOO zontally-turning rack H', centrally pivoted thereto, said rack being adapted to receive any desired number of fruit-trays. When the loaded car is run from the storm-room A4 into the drying-chamber and the hot-air blast from fan C' directed thereacross, the fruit will be quickly dried, when the car may be run into the examination-room A5, from which it may be returned to the drying-chamber, if necessary, to further dry the fruit, or the loaded car may be run over tracks B3 to the sulfur-room, or the trays of fruit may be removed and placed in the store-room. As the rack I-l is centrally pivotedto the car H, it may be reversed end for end for examination or to bring either side next to the fan C'.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-l l. The fruit-drier, comprising a dryingchamber, having a glass partition at one side, a water-spraying pipe behind said partition, a fan also located Within the chamber behind said partition and discharging` cold air thereagainst, and means for directing a hot-air blast over the fruit to be dried, and against said partition, substantially as set forth.

2. The fruit-drier, consisting in the main compartment, having a condensing-partition at one side of its drying-space, a fruit-carrier adapted to pass through said drying-space, a fan opposite the condensing-partition to force hot air over the substance to be dried and against said partition, a heater or furnace for heating the air supplied to said fan, and a blower for withdrawing the air from the drying-chamber and returning it to the heater or furnace substantially asset forth.

3. The improved fruit-drier, consisting of the main compartment, having end doors and a track between them, for the tray=carsg a condensing wall, or partition, set at one side' of and parallel to the track; means for spraying water and directing a blast of cool air upon said wall, for cooling it; a heater or furnace for heating the air; a fan for forcing the hot air across the track-space and the fruitladen car and against condenser-wall; and a blower for withdrawing the air from the drying-chamber and returning it to said furnace or heat-er, for reheating and drying, substantially as set forth.
