The present invention relates to a leaf tobacco drying apparatus that generates indirect hot air using chaff as a fuel and circulates the hot air into the drying chamber at a stepwise temperature to dry the leaf tobacco.

In general, the drying of the leaf tobacco has a characteristic of obtaining dry leaf tobacco of a certain quality, although the indirect hot air is continuously contacted with the circulating contact and the drying room temperature is gradually raised in a range of 38 ° C. to 72 ° C. according to the drying process.

On the other hand, there have been chaff burners that burn the chaff more economically than other fuels and use it as a direct heating heat source for cooking or heating. In view of the specificity of dry tobacco leaves, chaff fuel is not adopted for drying leaf tobacco because it is not suitable to generate a desired indirect hot air and it is difficult to adjust the temperature of the drying room to a proper temperature stepwise.

In order to solve the above-mentioned problems caused by adapting rice husk fuel to the leaf tobacco drying device, the present invention combusts rice hull, which allows to generate an indirect hot air at a predetermined temperature and keeps the hot air continuously in contact with the leaf tobacco drying process. It is possible to dry the leaf tobacco economically by fueling the dry tobacco of chaff which can be easily obtained from the farm while maintaining the drying room temperature at a proper temperature step by step.

On the side of the rice husk combustion chamber (1) having the backrest roaster (2) (2 '), the rice husk supply container (3) having the screw conveyor (4), the air supply vent (6), and the rice husk dispersion tuyer (6') The blower (5) which is combined is installed, and the screw conveyor (4) and the blower (5) are interlocked by chain gearing (7), and the air spraying hole (8 ') is located above the roaster (2) (2') inside the combustion chamber (1). ) Is equipped with a combustor (8) having a plurality of perforations to communicate the combustor (8) and the tuyeres (6), and to communicate the communication (9) so as to communicate with the up and down discharge research (10) (10 ') on the other side of the combustion chamber (1). In the normal chaff combustion apparatus installed, the main wall part of the combustion chamber 1 is formed by the double main wall body which has the hot air flow space 11, and the heat exchange tube 13 and the heat insulating plate of many heat exchange tubes 13 are installed above the combustion chamber 1 (14) (14 ') (14' ') is provided with a heat exchanger (12) is installed, the upper and lower ends of the heat exchanger tube 13 inside the heat exchanger (12) and the upper exhaust chamber (10) and the lower combustion chamber (1), respectively. ) Up and down study of communication (9) 10) A damper device 15 and 15 'for controlling flue gas, which are opened and closed by the interlocking lever, are installed in the 10'10', and the hot air blowing pipe 11 is formed from the upper and lower ends of the hot air distribution space 11 on the side wall of the combustion chamber 1 16) and the reflux pipe 16 'are guided to the upper and lower leaf tobacco drying chambers 17, respectively, and the upper and lower hot air blowing pipes 16 and the middle of the reflux pipes 16' are connected to the hot air circulation pipe 18 to communicate with each other. In the inner end of the return pipe 16 'and the middle of the circulation pipe 18, a damper device 19 (19') for regulating hot air, which is opened and closed by an interlocking lever, is provided. Intake fan 21, which blows in hot air, is a damper for controlling humidity emission which properly discharges and removes moisture contained in the cigarette itself according to the drying process.

This invention devises the chaff in the feed container 3 into the combustion chamber 1 with the screw conveyor 4, and is uniformly upward above the combustor 8 by the wind through the tuyeres 6 'of the blower 5. When the rice husk is burned together with the air supplied to the injection hole 8 'of the combustor 8 through the air supply port 6, the rice husk combustion heat is generated like a normal rice husk combustion device. When the lower operation lever of the flue control damper device 15 (15 ') mounted at (10') is stirred in the clockwise direction, the damper device (15) opens the upper drainage study (10) by the interlocking lever and the damper. The device 15 'prevents the bottom exhaust study 10' so that the combustion heat is directed upward through the heat exchange tube 13 of the heat exchanger 12 to the open top study 10 and then discharged into the communication 9. do.

Therefore, the heat of combustion passes the heat inside the heat exchanger 12 and heats the air around the heat exchanger tube 13, and the heated air is installed in the heat insulating plate 14, 14 ′, 14 alternately installed up and down around the heat exchanger tube 13. '') Is bypassed and ascended to receive sufficient heating to become indirect hot air for drying, and the hot air generated in this way is in the hot air blowing pipe 16 communicated through the hot air distribution space 11 of the side wall of the combustion chamber 1. After being sucked into the suction fan 20, it is sent into the drying chamber 17 to start the leaf tobacco drying.

On the other hand, when the heated air is fed into the drying chamber 17, the upper reflux tube 16 'and the damper device 19, 19' mounted in the circulation pipe 18 are controlled to open and close. 19 ') the operation lever attached to the clockwise agitation, the upper damper device (19) attached to the interlocking lever opens the hot air reflux tube 16' and the lower damper device (19 ') is a circulation pipe (18). Blocks the middle to prevent hot air passing through the drying chamber 17 from circulating itself through the circulation pipe 18 and is re-introduced into the heat exchanger 12 through the open reflux tube 16 'and heated, and then the drying chamber 17 The temperature in the drying chamber 17 is raised to a predetermined constant temperature by allowing the inside of the drying chamber 17 to be circulated.

Therefore, when the temperature in the drying chamber 17 reaches a proper temperature by heating and circulating the hot air in this manner, the hot air must be continuously circulated while maintaining the temperature for a predetermined time, so that the temperature of the circulated hot air can be circulated without further heating. The damper devices 15 and 15 'and the damper devices 19 and 19' for controlling the hot air are adjusted as follows.

That is, when the lower operation lever of the damper device 15 (15 ') is stirred counterclockwise, the upper damper device 15 interlocked with the interlocking lever is lower damper device 15' instead of blocking the upper drainage research 10. ) Opens the lower vessel study (10 '), the combustion heat in the combustion chamber (1) is not concentrated to heat the heat exchanger (12) and is discharged to the communication (9) through the open vessel study (10'). At this time, although not shown in the drying chamber 17 itself, a thermostat is provided to control the operation of the chaff feed screw conveyor 4 and the blower 5 to prevent further overheating and fuel waste.

In addition, when the damper device 19, 19 'for controlling the hot air stirs the operating lever at the bottom in a counterclockwise direction, the upper damper device 19, which is interlocked with the interlocking lever, blocks the reflux pipe 16' so that the hot air is exchanged again. Instead of preventing the inflow into (12), the lower damper device 19 'is interlocked to open the circulation pipe 18 to induce hot air to the blown pipe 16 so that the hot air in the drying chamber 17 is reheated. Without this, only drying itself is carried out step by step for a predetermined time. As such, the moisture contained in the leaf tobacco during the drying process is manually controlled to open and close the humidity control damper 21 installed in the reflux tube 16 'according to the dry state to remove and remove moisture.

Therefore, as described above, the temperature in the drying chamber 17 is maintained at a predetermined time step by step, and then the temperature is increased to the next step according to the drying process. The temperature rising in the next step is the flue gas damper device 15 (15 ') and the hot air. By re-adjusting the opening and closing amount of the damping device (19) (19 ') for adjustment as described in the opening and closing operation description described above, the temperature can be raised again in the next step, and the dry leaf tobacco of good quality can be obtained by repeating this step-up temperature. According to the present invention, the chaff is burned and used as a heat source for drying tobacco, but the hot air is generated as indirect heat by the heat exchanger, and the hot air is continued to be circulated as a damper device in accordance with the drying characteristics of the cigarette. Since the temperature can be arbitrarily adjusted step by step, cheap chaff can be used as fuel when high quality tobacco leaves are dried. Smoking dried and exhibits an effect that can be economical.
