Definitions

  • the grates are sealed against each other and against the longitudinal walls of the tunnel by elastic packing strips.
  • the grates at each end of the tunnel are sealed against the tunnel doors by similar strips. The sealing by the strips eifectively divides the t-unnel into separate upper and lower portions.
  • the present invention relates to an apparatus for moistening tobacco bales, which rest on a horizontal grating and are treated by means of moist air circulating through the bales and the grating.
  • a process is already known where the bales which rest on the grating of a chamber are moistened by means of a current of moist air, the moist air being admitted at the top of the chamber and drawn off from below the bales.
  • One of the main disadvantages of this process is the fact that the tobacco bales are not evenly moistened, i.e., they show different degrees of humidity, as there are varying climatic conditions within the chamber. This results from an uneven distribution of the moist air, which is admitted through an opening which is small when compared to the total area covered by the grating and the bales.
  • the process is characterized in that the tobacco bales are put on movable carrying grates used for conveying them from a store to a treating chamber and are conveyed into a tunnel adapted to be shut off tightly, and that the carrying grates are sealed off against the -walls of the tunnel, and that a current of moist air is passed in several successive intervals through the bales resting on the carrying grates with which they were supplied into the tunnel, and that after each interval some of the carrying grates with moistened bales are discharged from the tunnel while at the same time the same number of carrying grates with dry bales is supplied into the tunnel causing thereby the carrying grates still in the tunnel to be moved forward.
  • the carrying grates are gradually advanced through the tunnel, which according to the process is achieved by discharging some of the carrying grates from the tunnel and by supplying the same number of carrying grates into the tunnel, all bales pass through the various climatic zones in the tunnel under equal conditions, and therefore show the same degree of humidity 'when leaving the tunnel.
  • the carrying grates should suitably be arranged closely to each other, in order to obtain a large cover area.
  • this process also simplies and facilitates the handling of dry bales which can be put onto the carrying grates in the store for conveyance to the tunnel, whereby the packing tapes can also be put between the bales.
  • the duration of the moistening intervals between two feeding operations depends on the extent of humidity the bales are to have, and ou the amount, temperature, humidity, and pressure of the current or currents of moist air.
  • the apparatus for carrying out the process according to the invention is characterized in that the carrying grates are provided with gratings which are enclosed by frames, and in that the gaps between the frames and the longitudinal walls of the tunnel are sealed oif with elastic packing strips which rest closely on the frames in order to divide the tunnel horizontally into two sections by means of the gratings of these closely arranged carrying grates, and in that the tunnel doors, as well as the frames are provided with elastic packing strips so that the frames it closely to the doors of the tunnel and to the other frames.
  • the carrying grates and their packing against the longitudinal walls and the doors of the tunnel according to the invention not only ensure proper function of the grates extending over the whole tunnel, but also the easy and simple advance of the carrying grates through the tunnel.
  • FIGURES 1 to 3 show the apparatus in longitudinal sectional views along line I-I of FIG. 3 and along line -II-II of FIG. l, and in a transverse sectional view along line IIL-III of FIGURE 2;
  • FIG@ URES 4 and 5 show enlarged views of a section along line IVIV of FIG. 2 and of the front of the apparatus, and
  • FIGURES 6 ⁇ and 7 show a detail in a side and top View, respectively.
  • the tunnel as an embodiment of the apparatus serves to moisten tobacco bales 2 which rest on six carrying grates 1.
  • the carrying grates are moved through the tunnel in a specic movement, i.e., after each of the successive moistening intervals, which are completely alike in their conditions, the rst carrying grate in line is discharged from the tunnel, while another carrying grate loaded with dry bales is admitted into the tunnel, whereby the ve carrying grates which remain in the tunnel are advanced by the length of one grating. Consequently each carrying grate stays in the tunnel for six moistening intervals and passes through six tunnel sections; the various climatic zones in the tunnel are thereby equalized, achieving thus uniform moistening as desired.
  • the carrying grates are provided with undercarriages 3 and consist of gratings 5, enclosed by frames 4, and loaded with bales, whose tobacco leaves are in a vertical position in relation to the gratings. When aranged closely together, the carrying grates divide the tunnel horizontally into two sections 6, 7. In orderto produce moist air two air-moistening appliances are provided, which consist each of a ventilator 8, a heating device 9, and an air-moistener 10, and fitted into the longitudinal channels 11, 12.
  • the Imoist air in the tunnel should only penetrate the tobacco bales.
  • the areas of the lgrating 5, which are not covered by bales, have to be packed, just as the carrying grates have to be sealed off against each other, as well as against the doors 13, 14 and the longitudinal walls 15, 16 of the tunnel.
  • the packing of the empty spaces between the tobacco bales which rest on the carrying grate is done outside the tunnel by means of rubber or plastic bands 17, as is already known.
  • the frames 4 of the carying grates are wide enough-as can be seen from FIGURES 4 and 5-the outer edges of the bales rest on the frame so that it is not necessary to seal olf the frames.
  • the side faces of the frames which run across the tunnel are provided with elastic bands 18, made, e.g., of rubber, whereby elastic bands 20 are also attached to the doors at the level of the carrying grates.
  • the carrying grates are sealed olf against the longitudinal walls 15, 16 of the tunnel by means of packing rails 21 which run along the walls of the tunnel, closely adhere to them, and rest on the frames of the carrying grates during moistening.
  • This device On account of another device, which is provided on the floor of the tunnel and which is shown in FIGURES 6 and 7 apart from the tunnel -for reasons of clearness, one carrying grate is admitted, while another one is discharged, whereby the carrying grates which remain in the tunnel are advanced simultaneously.
  • This device consists of a cable pull 32 with two stable rollers 33, 34 and two movable rollers 36, 37, which are located on an axis, and are moved by means of a hydraulic cylinder 35. That part of the cable 38, which moves over the rollers 34, 36, is connected with bars 39, 40, which are moved in the direction of the piston rod 41 of the hydraulic cylinder.
  • the free ends of the bars are provided with noses 42, which cooperate with counter-supports 43, attached to the undercarriage for the advance of the carrying grates, and can be turned over against the advance direction when moving without load. Furthermore, outside the tunnel the bars run in grooves 44, tted into the platforms, so that they do not interfere with the ascending and descending of the carrying grates.
  • the longitudinal channels 11, 12, where the moistening appliances 8, 9, 10 are accommodated are provided with openings 45, 46 which lead into the upper section of the tunnel 6 and are located on the bottoms of the channels and close to their ends. Furthermore, there are chutes 47, 48 which are connected with the longitudinal channels through openings 49, 50, and with the lower section of the tunnel 7 through openings 51, 52.
  • the openings 45, 49 and 46, 50 cooperate with valves 53 and 54, respectively, which help to close either of the openings.
  • An apparatus for moistening tobacco bales comprising:
  • each of said carrying grates including a grating enclosed by a frame and defining a gap between each pair of adjacent frames
  • first elastic packing strips sealing off said gaps between said adjacent frames and said longitudinal walls of said tunnel respectively, and resting closely on said frames
  • roller support means mounted along said longitudinal walls of Said tunnel and below said packing strips
  • said carrying grates including undercarriages
  • said undercarriages being lifted from the oor of said tunnel.
  • said means for automatically raising and lowering said elastic packing strips comprises, link means moving said doors as trap doors, and cranks connected with said last-mentioned elastic packing strips by means of ropes,
  • axles supporting said link means on said longitudinal walls of said tunnel, and said cranks are provided on said axles.
  • said tunnel defines on its top at least one longitudinal channel
  • said at least one longitudinal channel communicating with the upper section of said tunnel
  • a chute providing communication with the lower section of said tunnel
  • valve means disposed in said at least one longitudinal channel, and connecting one end of said at least one longitudinal channel with said upper section of said tunnel and the other end of said at least one longitudinal channel with said lower section of said tunnel by means of said chute.
