Description

Technical Field

[0001] The utility model relates to the technical field of tea baking, in particular to a tea fermentation baking machine. Background Art

[0002] Baking tea is divided into two stages: first, baking out the moisture and green smell in the tea leaves to retain the fresh taste; second, after the moisture and odor in the tea leaves are removed, the aroma and taste will naturally improve, and then baking to the temperature and taste that the customer market likes. Therefore, it is extremely important to control the temperature when baking tea leaves. Because baking tea leaves requires a heat source, and because heat will be lost during transmission, the tea leaves need to be baked to a specific temperature. The temperature of the heat source must be greater than the temperature required for baking to ensure the efficiency of baking.

[0003] However, during the tea baking process, in order to make the temperature in the baking oven uniform to ensure the baking efficiency of the tea, the convection between the baking oven and the outside air will be reduced to reduce heat loss. The temperature of the heat source is higher than the temperature required for tea baking, and the heat loss in the baking oven is relatively slow, which causes the temperature in the baking oven to gradually increase, causing the temperature of the tea in the second half of the baking process to be higher than the temperature required for tea baking, affecting the quality of the finished tea. Utility Model Content

[0004] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a tea fermentation and roasting machine so as to solve the technical problems mentioned in the above background technology.

[0005] The above technical objectives of the utility model are achieved through the following technical solutions:

[0006] A tea fermentation and baking machine comprises a shell, a baking groove is provided on one side of the shell, a plurality of layers of supporting units for spreading tea leaves are arranged in the baking groove, an electric heating block for baking tea leaves is embedded in the bottom of the baking groove, and adjustment mechanisms for adjusting the temperature are arranged on both sides of the baking groove.

[0007] By adopting the above technical solution, the temperature in the baking tank can be automatically balanced through the provided adjustment mechanism to ensure that the temperature in the baking tank is always maintained in the optimal baking temperature range for tea leaves.

[0008] In a preferred example, the utility model can be further configured as follows: the adjusting mechanism includes a pressure chamber, a baffle and a limiting unit, a pressure chamber is opened in the shell, the pressure chamber is located on one side of the baking slot, a baffle is slidably connected in the pressure chamber, an inner side wall of the pressure chamber is provided with a limiting unit for clamping the baffle, an outer wall of the shell is provided with an exhaust groove that passes through the pressure chamber and is connected to the baking slot, and a through groove that matches the exhaust groove is opened on one side of the baffle.

[0009] By adopting the above technical solution, a pressure chamber is set up, so that the electric heating block can use the heat expansion of the pressure chamber to push the baffle up when baking tea leaves, so that the through groove and the exhaust groove overlap to allow convection between the air in the baking groove and the outside air, thereby dissipating heat and cooling down, avoiding excessive temperature in the baking groove.

[0010] In a preferred example, the utility model can be further configured as follows: the limiting unit includes a slide groove, a locking block and a permanent magnet; the inner wall of the pressure chamber is provided with a slide groove, a locking block is slidably connected in the slide groove, the side wall of the baffle is provided with a slot matching the locking block, and a permanent magnet for adsorbing the locking block is embedded in the slot.

[0011] By adopting the above technical solution, through the provision of locking blocks and permanent magnets, the gas in the pressure chamber will not immediately push the baffle up when the temperature in the baking tank increases due to the increase in the temperature of the baking tank. Instead, when the temperature in the baking tank exceeds the baking temperature range of the tea leaves, the baffle will be pushed up immediately for ventilation.

[0012] In a preferred example, the utility model can be further configured as follows: the depth of the slide groove is greater than the length of the locking block, and the top of one side of the locking block close to the slot and the top are both processed with inclined surfaces.

[0013] By adopting the above technical solution, through the inclined surface set on the locking block, when the baffle plate moves up, the inclined surface of the locking block can be squeezed through the slot to make the locking block slide into the slide groove, and the depth of the slide groove is greater than the length of the locking block, so the locking block can completely enter the slide groove, thereby preventing the locking block from blocking the baffle plate from moving up.

[0014] In a preferred example, the present invention can be further configured as follows: when the locking block is inserted into the slot, the through slot is located below the exhaust slot.

[0015] By adopting the above technical solution, when the baffle is reset and limited by the locking block, the through groove and the exhaust groove are separated, so that the gas in the baking groove is isolated from the outside air, avoiding continuous heat dissipation that causes the temperature in the baking groove to be too low and affects the quality of the tea.

[0016] In a preferred example, the utility model can be further configured as follows: the carrying unit includes a carrying plate, a handle and a slide rail, the inner walls on both sides of the baking slot near the opening are fixedly connected to the slide rails, a carrying plate is slidably connected between the two slide rails, and a handle is fixedly connected to one side of the carrying plate near the opening of the baking slot.

[0017] By adopting the above technical solution, the tea leaves can be baked in batches, and the tea leaves can be taken out easily after baking.

[0018] In summary, the present invention includes at least one of the following beneficial technical effects:

[0019] 1. The tea fermentation roasting machine can keep the roasting tank isolated from the outside air by means of the adjustment mechanism when the temperature does not exceed the roasting temperature range, and when the temperature exceeds the roasting temperature range, the baffle plate directly pops up to connect the through groove with the exhaust groove for ventilation, so as to reduce the temperature in the roasting tank to ensure the roasting effect of the tea leaves, and then the baffle plate will gradually slide down to separate the through groove from the exhaust groove again as the temperature decreases, so as to isolate the roasting tank from the outside, so as to achieve a better roasting effect of the tea leaves;

[0020] 2. This tea fermentation roasting machine can improve the roasting efficiency of tea by setting a carrying unit, and it is convenient to take out and replace the tea after the tea is roasted, making the tea roasting machine more practical. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0027] The utility model is further described in detail below in conjunction with the accompanying drawings. Example

[0028] Reference Figure 1 - Figure 4The utility model discloses a tea fermentation roasting machine, comprising a shell 1, a roasting groove 2 is provided on one side of the shell 1, a multi-layer supporting unit 3 for spreading tea leaves is arranged in the roasting groove 2, an electric heating block 4 for roasting tea leaves is embedded at the bottom of the roasting groove 2, and adjustment mechanisms 5 for adjusting the temperature are arranged on both sides of the roasting groove 2.

[0029] In this embodiment, the tea leaves are first spread on the supporting unit 3, and then the door of the shell 1 is closed to heat the baking groove 2 by the electric heating block 4, so that the temperature in the baking groove 2 is increased to bake the tea leaves. Because the temperature transfer is gradual, the temperature in the baking groove 2 will gradually increase, so the air in the pressure chamber 51 will also expand, thereby increasing the pressure in the pressure chamber 51 and increasing the thrust on the baffle 52.

[0030] As the temperature in the baking groove 2 gradually increases, until the baking process reaches the second half, the temperature gradually exceeds the optimal baking temperature range of the tea leaves. At this time, the pressure in the pressure chamber 51 will also gradually increase. When the thrust applied by the pressure chamber 51 to the baffle 52 is greater than the magnetic force of the permanent magnet 533 to attract the locking block 532, the baffle 52 is pushed upward by the pressure, thereby pressing the locking block 532 into the slide groove 531. Then, the baffle 52 that loses its obstruction will directly bounce up, causing the through groove 7 to overlap with the exhaust groove 6. Then, the air in the baking groove 2 is discharged and convects with the outside air, thereby reducing the temperature in the baking groove 2.

[0031] When the temperature gradually decreases, the air in the pressure chamber 51 will also shrink as the temperature decreases. Therefore, the thrust applied to the baffle 52 gradually decreases, and the baffle slowly moves downward until the through groove 7 is separated from the exhaust groove 6. The temperature in the baking groove 2 is restored to the optimal baking temperature range of the tea leaves. At this time, the position of the slot 8 is flush with the position of the slide groove 531, and the locking block 532 is sucked out by the magnetic force of the permanent magnet 533, so that the locking block 532 is reinserted into the slot 8 to fix the baffle 52, so as to avoid the air in the baking groove 2 from continuously convecting with the outside air and lowering the temperature, thereby ensuring the baking effect of the tea leaves and improving the quality of the finished tea leaves.

[0032] In a further preferred embodiment of the present invention, Figure 3 As shown, the adjustment mechanism 5 includes a pressure chamber 51, a baffle 52 and a limiting unit 53. The shell 1 is provided with a pressure chamber 51, and the pressure chamber 51 is located on one side of the baking slot 2. The baffle 52 is slidably connected to the pressure chamber 51, and the inner side wall of the pressure chamber 51 is provided with a limiting unit 53 for clamping the baffle 52. The outer wall of the shell 1 is provided with an exhaust groove 6 that passes through the pressure chamber 51 and is connected to the baking slot 2, and one side of the baffle 52 is provided with a through groove 7 that matches the exhaust groove 6.

[0033] In this embodiment, when the tea leaves are baked in the baking groove 2, the gas in the pressure chamber 51 will also expand as the temperature in the baking groove 2 increases. Therefore, the air in the pressure chamber 51 will slowly push the baffle 52 upward until the through groove 7 coincides with the exhaust groove 6, so that the air in the baking groove 2 and the outside air are convectively cooled. The frequent entry of outside air into the baking groove 2 will cause the tea leaves near the exhaust groove 6 to cool down and affect the baking effect, thereby reducing the quality of the tea leaves. Therefore, a limiting unit 53 is provided, and the limiting unit is used to impose restrictions on the baffle 52, so that the baffle 52 will not slowly move up as the gas in the pressure chamber 51 expands, but when the temperature in the baking groove 2 exceeds the optimal baking temperature range of the tea leaves, the baffle 52 directly pops up, so that the through groove 7 is connected with the exhaust groove 6 for ventilation. The through groove 7 is completely overlapped with the exhaust groove 6 to improve the ventilation efficiency, reduce the ventilation time, thereby reducing the contact time between the tea leaves and the low-temperature air, and then reduce the influence on the tea leaves, thereby ensuring the baking quality of the tea leaves.

[0034] In a further preferred embodiment of the present invention, Figure 4 As shown, the limiting unit 53 includes a slide groove 531, a locking block 532 and a permanent magnet 533. The inner wall of the pressure chamber 51 is provided with a slide groove 531, and the locking block 532 is slidably connected in the slide groove 531. The side wall of the baffle 52 is provided with a slot 8 that matches the locking block 532, and the slot 8 is embedded with a permanent magnet 533 for adsorbing the locking block 532.

[0035] In this embodiment, when the baffle 52 moves downward due to the contraction of the gas in the pressure chamber 51 due to the cooling, the limit unit 53 needs to be reset in order to reconnect the baffle 52 with the limit unit 53. The elastic reset method usually used will cause the locking block 532 to extend out of the slide slot 531 to reset after the baffle 52 moves upward. As a result, when the baffle 52 moves downward under the action of gravity, the bottom of the baffle 52 will contact the locking block 532, and the baffle 52 will be supported by the locking block 532 and cannot move completely downward, resulting in The through slot 7 and the exhaust slot 6 cannot be completely closed, which affects the baking of tea leaves. Therefore, the limiting unit 53 adopts a magnetic attraction method to move the baffle 52 down until the slot 8 is flush with the slide slot 531, and then use the magnetic force of the permanent magnet 533 in the slot 8 to suck out the locking block 532 and insert the locking block 532 into the slot 8, and use the magnetic force to reconnect the baffle 52 with the limiting unit 53 to avoid the locking block 532 blocking the baffle 52 from moving down, while allowing the baffle 52 to still be delayed in popping up when it is used next time.

[0036] In a further preferred embodiment of the present invention, Figure 4 As shown, the depth of the slide groove 531 is greater than the length of the locking block 532 , and the top and the top of one side of the locking block 532 close to the slot 8 are both processed with inclined surfaces.

[0037] In this embodiment, when the air pressure in the pressure chamber 51 gradually increases, the thrust applied by the air pressure to the baffle 52 will also gradually increase, and a locking block 532 is inserted into the slot 8 of the baffle 52. Therefore, if the baffle 52 is to be moved upward, the locking block 532 needs to be pressed into the slide groove 531. Therefore, by providing an inclined surface on the side of the locking block 532 close to the slot 8 (see Figure 3 ), when the thrust is greater than the magnetic force of the permanent magnet 533 that attracts the locking block 532, the baffle 52 can press the locking block 532 into the slide groove 531 when moving upward. Because the depth of the slide groove 531 is greater than the length of the locking block 532, the locking block 532 can completely slide into the slide groove 531 and separate from the baffle 52, so that the baffle 52 is no longer blocked. Therefore, the baffle 52 is pushed up by the air pressure to connect the through groove 7 with the exhaust groove 6 for ventilation.

[0038] In a further preferred embodiment of the present invention, Figure 3 As shown, when the locking block 532 is inserted into the slot 8 , the through slot 7 is located below the exhaust slot 6 .

[0039] In this embodiment, as the baking groove 2 is ventilated, the temperature in the baking groove 2 will gradually decrease. Therefore, the air in the pressure chamber 51 will also shrink as the temperature decreases, resulting in a reduction in the supporting force applied by the pressure chamber 51 to the baffle 52, causing the baffle 52 to move downward in the pressure chamber 51. As the baffle 52 moves downward, the slot 8 will gradually approach the slide slot 531 until it is flush with the slide slot 531. Then, the magnetic force of the permanent magnet 533 will suck the locking block 532 out of the slide slot 531, and insert the locking block 532 into the slot 8 to fix the baffle 52. Therefore, the baffle 52 will no longer move with the temperature change in the pressure chamber 51. Therefore, in order to avoid convection heat exchange between the gas in the baking groove 2 and the outside air, when the locking block 532 is inserted into the slot 8, the through slot 7 is completely separated from the exhaust slot 6 to avoid the gas in the baking groove 2 continuing to convection heat exchange through the gap between the through slot 7 and the exhaust slot 6.

[0040] In a further preferred embodiment of the present invention, Figure 2 As shown, the carrying unit 3 includes a carrying plate 31, a handle 32 and a slide rail 33. The inner walls on both sides of the baking slot 2 near the opening are fixedly connected with the slide rails 33. The carrying plate 31 is slidably connected between the two slide rails 33. The carrying plate 31 is fixedly connected with a handle 32 on one side of the carrying plate 31 near the opening of the baking slot 2.

[0041] In this embodiment, because there are many varieties of tea, and it is impossible to mix multiple types of tea together during baking, multiple supporting plates 31 are provided for spreading different teas so that tea leaves in the same baking temperature range can be baked at the same time to improve the baking efficiency of the tea leaves, and the handle 32 provided on one side of the supporting plate 31 can facilitate the removal of the tea leaves after baking, so that the tea leaves can be taken out more easily.

[0042] The embodiments of this specific implementation method are all preferred embodiments of the utility model, and are not intended to limit the protection scope of the utility model. Therefore, all equivalent changes made based on the structure, shape, and principle of the utility model should be included in the protection scope of the utility model.
