Traditional tea baking uses the smoke from the full combustion of charcoal to bake, so that the finished tea leaves will have the unique aroma of wood. However, in actual use, the smoke from the full combustion of charcoal contains large particles of impurities, which causes a large amount of impurities to adhere to the tea leaves, reducing the quality of the tea leaves and causing deficiencies in use. For this reason, we propose a smokeless charcoal baking stove. Summary of the invention

[0014] Beneficial effects of the present invention:

[0015] 1. The present invention provides a smokeless charcoal roasting stove. A stove chamber mechanism, a smoke removal mechanism and a connecting pipe are provided. A second fan is used to allow smoke from burning charcoal to enter the smoke removal mechanism through the connecting pipe. Large particles of impurities in the smoke are filtered out by multiple groups of filter elements in the smoke removal mechanism, thereby preventing smoke from burning charcoal from blowing directly onto tea leaves, thereby greatly improving the production quality of tea leaves.

[0016] 2. The present invention provides a smokeless charcoal roasting stove, which uses a drying mechanism and a feeding mechanism to dry tea leaves. When the smoke from the burning charcoal enters the drying chamber through filtering, the heat in the smoke is transferred to the heat transfer box, so that the temperature in the heat transfer box is increased, and the tea leaves are dried by heat radiation. At the same time, the internal smoke is blown to the tea leaves in the heat transfer box through the air pipe under the action of the first fan, so that the tea leaves are brought into the wooden box during the drying process, further improving the quality of the tea leaves.

[0017] 3. The present invention provides a smokeless charcoal roasting stove, which adopts a specially designed conveyor belt. The conveyor belt has a double-layer cavity structure and can run smoothly in a traditional tensioning conveyor belt mechanism. Existing equipment can be directly used for improvement, and it is only necessary to replace the transmission designed by the present invention. The conveyor belt can perform fragrant wood aromatherapy on the tea leaves from the inside to the outside during the tea drying process, thereby giving the tea leaves more natural flavor, providing the variety and diversity of tea leaves, improving the fragrance of tea leaves, and being purely natural and harmless. The process is integrated with the existing drying or conveying process through the conveyor belt designed by the present invention, without the need to set up an additional production line, replace the existing equipment, or make major modifications; the cost is low and the added value is high.

[0018] 4. The specially designed conveyor belt of the present invention utilizes a top block provided on the surface of the tensioning wheel, a planar module connected by a heat-resistant and highly elastic strip, and an inner and outer layer planar module supported and connected by an elastic metal sheet to achieve circular motion that fits the tensioning area, thereby realizing the conveyor belt motion mode of a double-layer belt cavity structure. When the conveyor belt moves to the tensioning area, since the transmission belt is a double-layer belt cavity structure; the circumference of the outer layer and the inner layer are different in size, and therefore the travel distances are different, under the jacking force of the top block, the planar module at the corresponding position of the inner layer is lifted toward the outer layer, and the two adjacent planar modules are first staggered up and down after the heat-resistant and highly elastic strip is stretched, and then because the travel distance of the inner layer is smaller than that of the outer layer and the angle change is also larger, the front and rear parts are displaced at the same time, so that the inner layer becomes shorter relative to the outer layer in the tensioning area, and the outer layer has a larger routing radius and a longer routing distance in the tensioning area. Under the guiding force of each elastic metal sheet, the distance between adjacent plane templates increases by a certain amount, but due to the large radius, the angle change is relatively small, so the misalignment is not obvious; through this structure, the length of the outer layer in the tensioning area becomes longer, and the length of the inner layer in the tensioning area is shortened. The corresponding angle and relative position changes between the plane modules located in the outer and inner layers automatically change and achieve balance under the elastic constraint of the elastic metal sheet, so that the inner and outer layers pass through the tensioning area smoothly and synchronously, and after losing the top force through the tensioning area, they return to the initial relative posture under the restoring force of the heat-resistant high elastic strip. This structure cleverly combines rigid structure and flexible structure, and uses the change of angle to actively stagger the inner layer up and down and front and back, and stretch the outer layer, thereby actively changing the length of the inner and outer layers in the tensioning area, thereby realizing the tensioning cycle action of large thickness and double-layer cavity structure. This structure is simple, clever, compact, stable in operation, long in service life, low in manufacturing cost, and wide in applicability. BRIEF DESCRIPTION OF THE DRAWINGS

The stove chamber mechanism 1 comprises a first base 11, a stove chamber 12 is installed on the top of the first base 11, a stove door 13 is installed on the side of the stove chamber 12 by bolts, a ventilating net 14 is installed on the stove door 13, a partition net 15 is installed inside the stove chamber 12 by bolts, the partition net 15 is clamped with the stove door 13, a combustion chamber 16 is installed at the inner bottom of the stove chamber 12, the combustion chamber 16 is located directly below the partition net 15, a connecting pipe 4 is installed on the top of the stove chamber 12, and the drying mechanism 2 comprises a second base 21, a drying chamber 22 and a feeder are installed on the top of the second base 21 The drying chamber 22 is provided with a heat conduction box 23, and the top and bottom of the heat conduction box 23 are provided with a first fan 24, the air outlet of the first fan 24 passes through the heat conduction box 23, and the air outlet of the first fan 24 is provided with an air pipe 25, and the air outlet of the second fan 34 is inserted into the drying chamber 22. The two sides of the drying mechanism 2 are provided with a smoke removal mechanism 3 and a feeding mechanism 5, respectively. The top of the smoke removal mechanism 3 is provided with a connecting pipe 4, and the connecting pipe 4 is connected with the cooking chamber mechanism 1. The smoke removal mechanism 3 includes a box body 31 installed on the side of the drying mechanism 2, and a sealing door 32 is installed on the side of the box body 31 by bolts, and the sealing door 32 and the box body 3 are connected. 1 is provided with a filter element 33, and the number of the filter elements 33 is several groups. A second fan 34 is provided on the side of the box body 31, and the second fan 34 is inserted into the interior of the drying mechanism 2. The connecting pipe 4 is provided on the top of the box body 31. By arranging the stove chamber mechanism, the smoke removal mechanism and the connecting pipe, the second fan is used to make the smoke from the burning charcoal enter the smoke removal mechanism through the connecting pipe, and the large particles of impurities in the smoke are filtered out by the multiple groups of filter elements in the smoke removal mechanism, so that the smoke from the burning charcoal is prevented from blowing directly to the tea leaves, thereby greatly improving the production quality of the tea leaves. The feeding mechanism 5 includes a support frame 51 fixed on the second base 21, and the interior of the support frame 51 is A first conveyor belt 52 and a fixed arm 54 are installed, a second conveyor belt 55 is installed between the two fixed arms 54, a first motor 53 is installed on the side of the first conveyor belt 52, and a second motor 56 is installed on the side of the second conveyor belt 55. The tea leaves are dried by a drying mechanism and a feeding mechanism. When the smoke from the burning charcoal enters the drying chamber through filtering, the heat in the smoke is transferred to the heat conduction box, so that the temperature in the heat conduction box increases, and the tea leaves are dried by heat radiation. At the same time, the internal smoke is blown to the tea leaves in the heat conduction box through the air pipe under the action of the first fan, so that the tea leaves are brought into the wooden box during the drying process, thereby further improving the quality of the tea leaves.

[0030] When in use, the device is connected to a power source, and the first fan 24, the second fan 34, the first motor 53 and the second motor 56 are started. The first motor 53 drives the first conveyor belt 52 to move, and the second motor 56 drives the second conveyor belt 55 to move. The second fan 34 sucks the air in the stove chamber 12 into the box body 31 through the connecting pipe 4, and blows it into the drying chamber 22 after being filtered by multiple groups of filter elements 33, and then blows it to the first conveyor belt 52 and the second conveyor belt 55 by the first fan 24. The staff puts a proper amount of charcoal into the combustion chamber 16 and ignites it, and then closes the stove door and the air permeable net 14 to provide sufficient air for the charcoal combustion. The smoke generated during the charcoal combustion is initially filtered through the partition net 15 and enters the smoke removal mechanism 3 through the connecting pipe 4. The large particles of impurities in the smoke are filtered out by multiple groups of filter elements 33 and then blown to the drying chamber 22. The heat in the filtered smoke heats the heat conduction box 23 to increase the temperature of the heat conduction box 23. The first motor 53 blows the filtered smoke to the first conveyor belt 52 and the second conveyor belt 55 through the air pipe 25. Tea leaves to be dried are put into the second conveyor belt 55. The tea leaves enter the heat conduction box 23 through the second conveyor belt 55, and then fall onto the first conveyor belt 52 after passing through the inclined plate 26 and are passed out. In this process, the heat in the heat conduction box 23 can effectively dry the tea leaves. At the same time, the smoke blown by the first fan 24 and the air pipe 25 can make the tea leaves adhere to the fragrance of burning charcoal, thereby greatly improving the quality of drying the tea leaves.

[0031] Compared with the prior art, the present invention provides a stove chamber mechanism, a smoke removal mechanism and a connecting pipe, and utilizes a second fan to allow the smoke from the burning charcoal to enter the smoke removal mechanism through the connecting pipe, and the large particles of impurities in the smoke are filtered out by multiple groups of filter elements in the smoke removal mechanism, thereby preventing the smoke from the burning charcoal from directly blowing onto the tea leaves, greatly improving the production quality of the tea leaves, and simultaneously adopting a drying mechanism and a feeding mechanism to dry the tea leaves, and when the smoke from the burning charcoal enters the drying chamber through the filter, the heat in the smoke is transferred to the heat transfer box, so that the temperature in the heat transfer box is increased, and the tea leaves are dried by heat radiation, and simultaneously the internal smoke is blown onto the tea leaves in the heat transfer box through the air pipe under the action of the first fan, so that the tea leaves are brought along with the wooden box during the drying process, further improving the quality of the tea leaves.

[0032] In addition, see Figures 4 to 8Furthermore, in order to increase the aroma of tea according to process requirements, the first conveyor belt 52 and the second conveyor belt 55 of the present invention are specially designed. The first conveyor belt 52 and the second conveyor belt 55 have the same structure, and respectively include an inner layer 61 and an outer layer 62 arranged at a distance; the tea leaves are spread flat on the upper surface of the outer layer 62; the inner layer 61 and the outer layer 62 respectively include a plurality of planar modules connected in sequence along the length direction of the conveyor belt; two adjacent planar modules are connected by a heat-resistant high-elastic strip 60; the planar module includes left and right cross bars 63 arranged in parallel; an elastic metal sheet 64 is supported and connected between the corresponding cross bars 63 of the two corresponding planar modules inside and outside; an electric heating plate 65 is fixedly connected between the left and right cross bars 63 of the planar module located in the inner layer; a porous plate 66 is fixedly connected between the left and right cross bars 63 of the planar module located in the outer layer; a filling plate 65 is clamped between the electric heating plate 65 and the porous plate 66 There are fragrant wood particles 67; a plurality of protruding top blocks 69 are evenly arranged on the outer circumferential surfaces of the tensioning wheels 68 of the first conveyor belt 52 and the second conveyor belt 55 respectively corresponding to the planar modules located in the inner layer; when the first conveyor belt 52 and the second conveyor belt 55 move to the tensioning position, the top blocks 69 push up the planar modules located in the inner layer, so that the adjacent planar modules are staggered up and down and the front and back parts are misaligned after stretching the heat-resistant high elastic strip 60; at the same time, in the tensioning position range, the distance between the adjacent planar modules located in the outer layer is slightly pulled, and the corresponding angles and relative position changes between the planar modules located in the outer and inner layers automatically change and achieve balance under the elastic constraint of the elastic metal sheet 64, so that the inner layer 61 and the outer layer 62 pass through the tensioning area smoothly and synchronously, and restore the initial relative posture under the restoring force of the heat-resistant high elastic strip 60 after losing the top force after passing through the tensioning area.

[0033] A plurality of electric heating rods 70 or heat conducting plates are arranged perpendicular to the inner surface of the electric heating plate 65 .

[0034] Side baffles that are detachably fixed relative to the drying chamber 22 are provided on both sides of the first conveyor belt 52 and the second conveyor belt 55; the side baffles slide against the side surfaces of the first conveyor belt 52 and the second conveyor belt 55 to prevent the fragrant wood particles 67 from escaping.

[0035] The heat-resistant high elastic strip 60 and the electric heating plate 65 are connected and separated by the heat insulation strip 71; the heat-resistant high elastic strip 60 is a heat-resistant, non-toxic, odorless and highly elastic polymer composite rubber or composite silica gel or composite silicone rubber, such as nitrile rubber.

[0036] When in use, the outer layer 62 and the inner layer 61 are filled with selected fragrant wood particles, and the tea leaves are spread flat on the upper surface of the outer layer 62. As the tensioning wheel 68 drives the transmission belt to move into the drying chamber for heat drying, when it moves to the tensioning area, since the transmission belt is a double-layer belt cavity structure; the circumferences of the outer layer 62 and the inner layer 61 are different, and therefore the travel distances are different. Under the top force of the top block 69, the planar modules at the corresponding positions of the inner layer 61 are lifted toward the outer layer 62. After the heat-resistant high-elastic strip 60 is stretched, the two adjacent planar modules are first staggered up and down. Then, since the travel distance of the inner layer 61 is smaller than that of the outer layer 62 and the angle change is also larger, the front and rear parts are staggered at the same time, so that the inner layer 61 is relative to the outer layer 62 in the tensioning area. The outer layer 62 in the tensioning area has a larger radius and a longer routing distance. Under the guiding force of each elastic metal sheet 64, the distance between adjacent plane templates increases by a certain amount. However, due to the larger radius, the angle change is relatively small, so the misalignment is not obvious. Through this structure, the outer layer 62 in the tensioning area becomes longer, and the inner layer 61 in the tensioning area becomes shorter. The corresponding angle and relative position changes between the plane modules located in the outer layer 62 and the inner layer 61 automatically change and achieve balance under the elastic constraint of the elastic metal sheet 64, so that the inner layer 61 and the outer layer 62 pass through the tensioning area smoothly and synchronously, and after passing through the tensioning area and losing the top force, they return to the initial relative posture under the restoring force of the heat-resistant high elastic strip 60. This matches the circular motion of the tensioning area and realizes the motion mode of the conveyor belt with a double-layer cavity structure.

[0037] At the same time, the electric heating plate 65 and the electric heating rod 70 are controlled by the control system to heat up, and the fragrant wood particles 67 therein are gently baked, so that they release smokeless wood fragrance outward, and the wood fragrance passes through the porous plate 66 to fumigate the tea leaves, making the tea leaves have more diverse fragrances. It is natural, safe and non-toxic, and is a good processing method; the heating temperature of the electric heating plate 65 and the electric heating rod 70 can be within the safe working range of the heat-resistant high elastic strip 60, and the corresponding temperature process can be changed with the selection of different safe heat-resistant high elastic strips 60.
