This invention relates to a dehydrating unit.
An object of the invention isthe provision of a unit having a self contained curing compartment in close association with a dry irig compartment, with the compartments so associated that the greater portion of the heat will be directed into the curing compartment while a lesser portion will be applied to the articles in the drying compart ment.
A further object of the invention isthe provision of a dehydrating unit including a housing having a curing compartment in communication at'the bottom thereof with the housing and a drying compartment located above the curing compartment and open to the air in the housing, an oscillating fan being employed for causing the hot air in the compartment to be forced in an alternate series through a plurality of trays forming the drying compartment.
This invention will be best understood from a consideratiouof the following detailed description in connection with the accoinpanying drawings; nevertheless, it is to be understood that the invention is not confined to the disclosure being susceptible of suchchanges and modifications as shall define no material departure from the salient features of the invention" as expressed in the appended claims.
In the drawings Figure 1 is a view in perspective with parts of the dehydrating unit broken away, [Figure 2 is a view in'perspective with parts broken away showing the air conduit,
Figure 3 is a fragmentary view in elevation of the front of the dehydrating unity Figure 4 is a vertical section of the unit.
v Figure 5 is a horizontal section taken along the line 5'5 of Fig. 4,
Figure 6 isa view in perspective of. a clip supporting the outer free end of the air conduit. I
Referring more particularly to the drawings 1O designates a housing having a' door 11 hinged at 12 for closing the entrace to the housing. Keepers 13 are provided for maintaining the door closed. The top 14 of the housing is provided with a discharge conduit 15 for conducting the hot air and gases away from the interior of the housing, the bases being supplied by a burner 16 of any well known type. Apipe 17 is connected with an opening 18 in the rear wall 19 of the housingfor conducting hot air and gases from a curing chamber 20 formed. in the lower portion of the housing The upper portion of the housing, as shown at 21, forms a drying chambers A baffle- 22 is spaced from the top 14 of the housing and terminates at 23 adjacent the rear wall 19 so} that warm air is discharged from the chambe'rrQlat the rear upper end of said chamber before it reaches the discharge pipe 15. i
The curingchamber is formedby a housing'24: which-has its lower end open to the housing while side walls 25, front end wall 26 and rear wall'27, which constitutes part of the rear wall-19 of the housing 10, and
chamber. A plurality oftrays 29, 30 and 31 are located in spaced parallel relatioirwithin the housing 24 and'are adapted to-receive the products to be cured. Side 'fianges. 32 aid in maintaining the articles on said trays. These trays abut the rear wall 19 of the housing 10f and are spaced from the front end wall 26 to provide a passage 33 forthe hot air. 1 The trays 29 to 31 inclusive, are tilted at an angle tothe horizontal so *that a top 28 all cooperate to-provide a curing I their inner ends are at a lower level than the rear ends." A door 34 provides a closure for an opening 35in thefront end 26 of the housing 24.
'A pipe 40 has'an open end 41 terminating at the front of the housing 10- and sup ported at said end by a clip 42"secured to the'bottom of said housing and below the door 11. The rear end is secured to the hottom 43 of the housing 10 and has a port 44 leading into the curing chamber 20. A bafile plate 45 is tilted at an angle-to the horizontal and supported by the side walls 16 of the housing 10 and terminates adjacent the lower-end of the front portion 26 of the housing 24. The heater 16 is located below the baflie plate 45 and the hot air from said heater is directed by the bafile into the lower open end of the curing chamber.
A- plurality of trays are arranged in spaced relation within the drying chamber 21 andare-supported by vertically disposed bars 51 secured to the side walls 46 of the housing 10. 'These trays have their forward ends at a lower level'than the rear ends and are adapted to support articles to be dried Flanges 52 are secured to theside edges of thetrays to prevent the materials from being discharged from the trays. It is to be uppermost tray 50, and all of the succeeding traysare progressively spaced from the door 11 by a greater distance, thereby providing a greater space between the front ends of the lowermost trays and the door 11 than the upper trays. The rear end of the uppermost trays are spaced a greater distance from the rear wall 19 than the lowermost trays. V 1
An oscillating fan 60 is driven by'an elec tric motor 61, secured to the door 11', and is v adapted to force the hot air continuously through the spaces between the trays 50, and 50 towards the rear wall 19 of the housing 10. Since this fan is of the oscillating type the air will be forced through either of the lower or uppermost trays initially after which the air is progressively forced through the other trays until the fan reverses its position when the reverse supply of air is had. By this construction the air is maintained ina constant state of agitation and all the trays are equally supplied with a predetermined quantity of hot air.
By opening the door 84 more air is forced through the front end of the housing 24 and thus through the trays 29 to 31 inclusive. The greater portion of this air, however, is forced through the curing chamber and out through the discharge pipe 17. The remaining portion of the air which is, supplied by the conduit 40 is driven by the fan 60 through the trays in the drying-chamber 21 after which said air is discharged past the rear end 28 of the baffle 22, and out through the discharge pipe 15. A screen 62 is mounted in the pipe 40 and aids in remov-' ing foreign matter from the air before it is received within the curing chamber 20.
