R. ZIMMERMANN in BAUTZEN. T r ο c ke η ap ρ arat for fruit and vegetables.

Patented in the German Empire on August 23, 1885.

This apparatus is intended in good achievement of the dehydrator purpose and easy handling by means of the new hoist advantage possible, lower by arranging height extension position themselves in husbandry areas of only ordinary height and let _λ besides use his real purpose as an air heating furnace and the fuel.

According to the accompanying drawing, it consists of three main parts screwed together:

ι. the underframe respectively. the boiler room H,

2. the (preheater F,

3. the tray guide frame F.

The boiler room H is formed from an iron frame with partly removable sheet metal walls, which are lined with chamotte or other protective material to avoid too much heat loss. It contains the heating furnace O with the ash box underneath and the ash pan and above it the heat distribution rosette R which can be moved on a pin. The cover plate of the heating furnace is shaped like a saddle so that the air to be heated can be better smeared. On the rear wall of the same there are two heating pipe sockets, into which the heating pipes are now connected, which run through the preheater V in parallel in an ascending and descending arrangement until they continue to the forge when they exit through a common smoke pipe Z. These heating pipes are stored on the iron frame of the preheater and have closable openings at the bend points above and below with connecting pieces for easy cleaning.

The preheater V is closed to the outside by sheet metal walls, which can be removed on the sides and above. The air inflow opening with adjustable flap K, through which the air circulation can be regulated, is located on the rear face of the same.

Resting on the boiler room, the tray guide frame F rises with the drying trays. The same consists of four corner columns made of LJ and L-iron, which are connected to each other by cross rails and cross bracing and to which the new tray lifting device is attached. This now consists of the shaft W, which is supported on the two i_i columns of the insertion side E by means of bearing jaws L and at the two laterally protruding ends a chain drum t with two chain grooves and ratchet teeth, as well as a crank are attached. At the same height, a roller r is attached to each of the other L-pillars, the groove of which lies in the same plane with one of the grooves of the corresponding drum. At each Trom ^ t mel two lifting chains are fastened, of which the one directly after the lifting beam / j ^1, the other r on the role after the lifting beam h ^'2 leads. This lifting beams are mutually at the ends by means of articulated links g by the guide bar Z ^"1/2 connected to the ends of which slanted fins χ χ as supports for the joint members g are located. The guide bar get their guide to the frame columns by small

Claims (1)

Slide and through the slide rails 5 s, which also form their rest position. Furthermore, two equilibrium links ii are attached to each of the guide bars f ^l f ² , from the junction of which a chain j runs over the track roller u to the lever frame m and is fastened there at ο. This lever frame spans the tray guide on three sides, has a cranked handle in the middle on the insertion side E and finds its support or support with the leg ends on the corner pillars. Fulcrums d; so that .When this lifting lever frame by the chains j and the guide beams f ^1/2 mitsammt the designed lift beams h ¹ / i to be lifted. ² Furthermore, the wooden drying trays to be pushed into the guide frame are provided on two opposite sides with iron noses nn in the form shown, into which the lifting beams h ^l h ² engage lifting when they go up or slide over them when going down. The apparatus works in the following way: The combustion gases produced in the furnace are drawn off by means of the heating pipes described through the preheater and the smoke pipe Z to the forge, while the air flows through the regulating flap K in the opposite direction through the preheater and here at the heating pipes is preheated to a high degree. It is heated further in the boiler room and then, evenly distributed by the wind rosette R , passes through the trays above, covered with fruit, etc., in order to escape freely at the top or to be sucked off by an air oven by means of a hood located above. If the dried trays behufs the dry Processes in the tray guide from the bottom upwards are moved and PUFA raised accordingly the insertion of the same take place below so are for this purpose by rotation of the crank and thus successful forming windup of the pulling chains that fastened to the latter lifting beam / j h; these lie against the iron noses η η of the lowest horde and lift them up together with the hordes on them in order to make space free for another horde. If this is pushed in, the pull chains are left behind, the lifting beams /; h slide it over the bridge of the nose of the inserted Horde down and lie down by means of the links gg on the oblique ribs χ χ of the guide bar for ^half off again after the latter ss in the runners their resting point found. If the tray is to be changed from top to bottom and consequently the bottom tray is to be pulled out, the lever frame m is raised; by means of the chains j attached to each leg, the guide bars ff, together with the lifting bars hh, follow the upward movement. The lifting beams initially remain in the laid-out position and freely pass the noses of the lowest horde. Once this is done, the lifting chains are tightened by means of the crank; the lifting bars hh grip into the noses η η of the second shelf and lift this up, together with the insert above, so that the lowest shelf becomes free and can be pulled out, whereupon the rest of the shelf insert is lowered by means of the crank. Meanwhile, the lever frame on its retirement, the projections of the shaft bearings L, has been left behind. To make it easier to slide in the tray, a tray template / is attached to the underframe H and a podium ρ is placed underneath. For dryers of larger dimensions, the inclusion of an intermediate gear for the elevator is also provided. Patent claim: A drying apparatus with the air preheating space V attached to the side with the air inflow and regulating flap K, through which the heating tubes are led from the furnace O to the flue pipe Z , as well as with a lifting device, the lifting beams of which extend so far at the resting point that they over the lifting lugs the hordes can be lifted away, which is achieved by the chain drums tt and the rollers rr with the four lifting chains, which are attached to the ends of the lifting beams, the ribs χ χ and the balance links ί i on the guide bars ff-, the sliding rails ss on both sides , the chains j, the tracking rollers u and the lever frame m.
