lrce revolution off said` conduit-1.V The conduitf 3G is hereshown as branching, laterally 'fourv waysv at Yits upper end as. at` 37e-37kg STL-37. and abouti midway the height ot drawnf from ai heater-"13,
lo are arrangedsix joists 19,` point ad) wentwalh 2. Uponl the corresponding sides of each chamber 3, each branch having a pipe section as 38 adjustably mounted thereon by adjusting and supporting brackets 39. Pipe 38 is flattened out to form a long narrow discharge nozzle 40 having its mouth arranged parallel with shaft 33 and spaced a little way from the inner ends ot' trays 30 as shown. At 4l is shown a diffusion vane adjustably mounted at the end ot nozzle 40 inthe relative position shown. The adjustment is effected lby means ot' a .bracket 42 mounted 0n each end ot nozzle 40 and provided with a curved slot 43, the vane carrying bars 44 provided with oritices and bolts 46. By means ot this construction the vanes may 'be placed close to the nozzle 40 or spaced a distance therefrom at either end, and it may be placed at any desired langle to the normal air How through said nozzle.
Passing upwardly trom the center ot conduit 36 is a conduit 47 having an opening 49 intol the space 48 between ceiling 4 and root 5, this opening `being controlled. by a valve 50 hinged at 51 and operated by a rod At 53 is shown another conduit communicating with conduit 47 and heater 13, the valve 50 closing this conduit when opening passage 49 and vice versa.
In conduit 36 are provided a number ot small orifices as 54, for the purpose hereinatter described.
ln loading the dehydrator the trays are trucked into and deposited in one compartment as A, the lever 27 being operated to revolve the table as described thereby bringing compartmentl B into alignment with the door. Each of the remaining compartments are now successively brought in to position and loaded, upon which thedoor is closed.
The fan being started, heated air is driven through conduits 11, 17 and 36 out through nozzles 40 into chamber 3 and impinging upon the several vaines. The vanes being set to direct the air trom all ot the nozzles in the same direction, the reaction causes shaft 33 and all the parts mounted thereon to revolve, thereby securing a thorough and uniform distribution ot' the air through and around all ot the trays 30.
The air discharged into chamber 3 is driven out into space 48 and thence to the atmosphere. Since the air trom nozzles 40 is driven outwardly to the circumference ot the chamber there is a. suction created at the upper and lower ends ot the revolving nozzles tending to create an air circulation suoli as indicated by arrows Air circulating in this manner would lill the center of the chamber with moist air and inter-tere somewhat with the success'tul operation ot the dehyrator. To obviate this dilliculty l provide several small orifices in conduit 36 so that a small amount ot warm dry air is being constantly fed into the center of the chamber and the undesired tlow ot air above referred to eliminated.
By opening valve 50 in conduit 47, to close conduit 53, the air will be discharged direct into chamber 48. It the air is not sutliciently heated, then the valve 50 is opened with respect toV conduit 53 and closes opening 49 so that a quantity ot' heated air is drawn from conduit 36 through conduits 47 and 53 to be reheated to a higher temperature in heater 13 and again mixed with dehydration air and passed through conduit. 11. Valve 5() is shown as a double leat' valve, one leaf as 50u being operable by a separate rod 50b so that both opening 49 and conduit may be closed at the same time when no variation in the temperature o't the dehydration air is desired.
