Description

Technical Field

[0001] This invention relates to the field of tea roasting, and in particular to a tea roasting machine. Background Technology

[0002] Roasting tea, also known as stir-frying tea, is an ancient tea-making technique that involves baking tea over a low flame. Tea roasting is often the final step in the tea-making process. Its purpose is to evaporate excess moisture from the tea leaves, promote the thermal transformation and aroma development of the leaf components, enhance and fix the quality, and facilitate storage. This is a scientific tea-making method adopted by the ancients that combines roasting with storage, thus both storing and cultivating the tea.

[0003] Existing technology uses electric heating to roast tea leaves. First, the tea leaves are evenly spread on a tray, and then the tray with the tea leaves is placed in the roasting chamber of the roasting machine. Then, the tea roasting machine is started, and the electric current supplies energy to the heater at the top of the roasting machine. The heater transfers heat energy to the air in the roasting chamber, raising the temperature inside the machine to roast the tea leaves.

[0004] However, since the tea leaves cannot be turned over, the unturned parts of the leaves will remain in the same position in the oven. This causes the side in contact with the heat source to overheat while the other side may not be heated sufficiently. This results in uneven drying of the tea leaves. Due to uneven heating, some tea leaves may be over-roasted, causing them to lose their original flavor and nutrients, and even develop unpleasant tastes such as burnt or bitterness. At the same time, the moisture in other tea leaves cannot evaporate evenly, affecting the aroma and color of the tea. Summary of the Invention

[0005] The main objective of this invention is to provide a tea roasting machine that solves the problem of tea leaves that cannot be turned over, which would remain in the same position in the oven, causing the side in contact with the heat source to overheat while the other side may not be sufficiently heated. This results in inconsistent drying of the tea leaves, affecting their subsequent preservation and taste.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0007] A tea roasting machine includes an outer shell and a sealing door hinged to the outer shell, as well as a drying mechanism connected to the outer shell, a flipping mechanism disposed inside the outer shell, and a dehumidification mechanism disposed on the outer wall of the outer shell.

[0010] The dehumidification mechanism includes a delivery pump fixedly connected to the top of the outer casing for drawing air from inside the outer casing, and a drying chamber fixedly connected to the outer wall of the outer casing. The air outlet of the delivery pump is connected to the interior of the drying chamber through a pipe.

[0011] Preferably, the driving component includes a servo motor fixedly connected to the top of the housing and a transmission rod fixedly connected to the output end face of the servo motor.

[0012] Preferably, the drive unit further includes a mounting bracket fixedly connected to the outer wall of the transmission rod, and an electric lift fixedly connected to the bottom of the mounting bracket;

[0013] The top of the electric heating plate is fixedly connected to the output end face of the electric lift.

[0014] Preferably, the tray includes a rectangular frame, a support mesh fixedly connected to the inner sidewall of the rectangular frame, an insertion groove opened on the outer sidewall of the rectangular frame, a locking groove opened on the inner sidewall of the insertion groove, a guide hole penetrating the sidewall of the rectangular frame, and a locking groove opened on the top of the rectangular frame.

[0015] Preferably, the flipping mechanism further includes a guide rod fixedly connected to the outer wall of the mounting plate and a rectangular frame, wherein there are four guide rods arranged in a rectangular array.

[0016] Preferably, the flipping mechanism further includes an electromagnet embedded inside the rectangular frame, a spring groove opened at the bottom of the rectangular frame, a connecting spring fixedly connected to the bottom of the spring groove, and a locking block fixedly connected to the end face of the connecting spring. The outer diameter of the locking block is equal to the inner diameter of the locking groove. The overall structure consisting of the spring groove, the connecting spring, and the locking block has two sets.

[0017] Preferably, the flipping mechanism further includes a storage chamber fixedly connected to the outer wall of the outer shell, an electric push rod fixedly connected to the inner wall of the storage chamber, a transmission plate fixedly connected to the output end of the electric push rod, a storage groove formed on the outer wall of the transmission plate, an electric telescopic rod fixedly connected to the inner wall of the storage groove, a locking rod fixedly connected to the output end of the electric telescopic rod, and a limiting rod fixedly connected to the outer wall of the output end of the electric telescopic rod. The longitudinal section of the transmission plate matches the longitudinal section of the insertion groove, and the outer diameter of the locking rod is equal to the inner diameter of the locking groove.

[0018] There are two trays, one of which is fixedly connected to the outer wall of the mounting plate, and the other of which is fixedly connected to the outer wall of the transmission plate.

[0019] Preferably, the dehumidification mechanism further includes a hinged door connected to the drying chamber, several parallel partitions fixedly connected to the inner side wall of the drying chamber, through holes opened on the top of the partitions, and solid desiccant placed on the top of the partitions. Each partition has a set of through holes on its top, and the through holes are arranged in an alternating pattern.

[0020] Preferably, the dehumidification mechanism further includes a humidity sensor and a buzzer fixedly connected to the inner wall of the drying chamber, wherein the humidity sensor is located in the lower half of the drying chamber.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] I. In this invention, tea leaves are laid on the support net of the tray, then the sealing door is opened, and the guide hole is fitted onto the outer surface of the guide rod until the tray can no longer be pushed. At this time, the locking groove will be aligned with the spring groove. Then the electromagnet is de-energized, and the locking block will extend one end to the outer surface of the spring groove under the action of the connecting spring and be inserted into the locking groove, thereby fixing the tray. Then the electric heating plate is activated, and the height of the electric heating plate is adjusted by the electric lift to dry the tea leaves.

[0023] II. In this invention, the servo motor is activated to drive the transmission rod to rotate 90°, aligning the guide rod with the guide hole of the other tray. Then, the electric push rod is activated to move the other tray toward the transmission rod. During this process, the electromagnet is energized, causing it to attract the locking block and compress the connecting spring until the locking block is completely inside the spring groove. When the limiting rod abuts against the lower tray, and the guide hole of the upper tray fits onto the outer surface of the guide rod, and the outer wall of the upper tray abuts against the mounting plate, the electric telescopic rod is then activated to extend and retract, causing the locking rod to disengage from the locking groove. At this time, the electromagnet is de-energized, allowing the locking block to insert into the locking groove, thus fixing the two trays. Then, the electric push rod is activated to drive the transmission plate out of the insertion groove. Then, the flipping motor is activated to rotate the mounting plate 180°, thus transferring the tea leaves from the lower tray to the upper tray, achieving the flipping of the tea leaves. After the flipping is completed, the transmission plate is reconnected to the tray to remove the tray, ensuring the drying effect of the tea leaves.

[0024] III. In this invention, by activating the delivery pump, the air containing moisture generated during the drying process is delivered to the interior of the drying chamber. Several partitions and through holes are installed to extend the air circulation time inside the drying chamber, thereby improving the dehumidification effect of the solid desiccant. Finally, the dehumidified air is delivered back to the interior of the outer shell by the action of the right-angle tube, thereby promoting air circulation inside the outer shell, making full use of the heat inside the outer shell, reducing heat loss, and ensuring that heat can be evenly transferred to the surface of the tea leaves.

[0025] IV. In this invention, a humidity sensor is used to detect the humidity inside the drying chamber. When the humidity sensor detects that the humidity inside the drying chamber is too high, a buzzer will be activated to remind the operator that the solid desiccant needs to be replaced. At this time, the operator can replace the solid desiccant by opening the hinged door. Attached Figure Description

[0043] The drive unit also includes a mounting bracket 303 fixedly connected to the outer wall of the transmission rod 302, and an electric lift 304 fixedly connected to the bottom of the mounting bracket 303;

[0044] The top of the electric heating plate 305 is fixedly connected to the output end face of the electric lift 304. The height of the electric heating plate 305 is adjusted by the electric lift 304 to adapt to the drying of different teas.

[0045] The tray 404 includes a rectangular frame, a support mesh fixedly connected to the inner side wall of the rectangular frame, an insertion groove opened on the outer side wall of the rectangular frame, a locking groove opened on the inner side wall of the insertion groove, a guide hole penetrating the side wall of the rectangular frame, and a locking groove opened on the top of the rectangular frame.

[0046] The flipping mechanism also includes guide rods 403 and rectangular frame 405 fixedly connected to the outer wall of the mounting plate 402. There are four guide rods 403, which are arranged in a rectangular array. The outer diameter of the guide rods 403 is equal to the inner diameter of the guide hole. By allowing the guide rods 403 to pass through the guide hole, the outer wall of the tray 404 abuts against the outer wall of the mounting plate 402. At this time, the opening of the rectangular frame 405 will be directly opposite the opening of the tray 404, and the bottom surface of the rectangular frame 405 will be in contact with the top surface of the tray 404.

The two sets of overall structures are symmetrically arranged about the mid-section of the electromagnet. The locking block 407 is made of ferromagnetic material. When the electromagnet is energized and has magnetic force, it will attract the locking block 407, causing it to compress the connecting spring 406 until the locking block 407 is completely located inside the spring groove. When the electromagnet is de-energized and loses its magnetic force, the locking block 407 will extend to the outer surface of the spring groove at one end under the action of the connecting spring 406.

[0048] By laying the tea leaves on the support net of the tray 404, opening the sealing door 2, and fitting the guide hole onto the outer surface of the guide rod 403 until the tray 404 can no longer be pushed, the locking groove will be aligned with the spring groove. Then, the electromagnet is de-energized, and the locking block 407, under the action of the connecting spring 406, extends one end to the outer surface of the spring groove and is inserted into the locking groove, thereby fixing the tray 404. Then, the electric heating plate 305 is activated, and the height of the electric heating plate 305 is adjusted by the electric lift 304 to dry the tea leaves.

[0050] Please refer to Figure 1-10 As shown, the present invention is a tea roasting machine, including an outer shell 1 and a sealing door 2 hinged to the outer shell 1, as well as a drying mechanism connected to the outer shell 1, a flipping mechanism disposed inside the outer shell 1, and a dehumidification mechanism disposed on the outer wall of the outer shell 1.

[0053] The dehumidification mechanism includes a delivery pump 501 fixedly connected to the top of the outer casing 1 for drawing air from inside the outer casing 1, and a drying chamber 502 fixedly connected to the outer wall of the outer casing 1. The outlet of the delivery pump 501 is connected to the interior of the drying chamber 502 through a pipe.

[0054] The tray 404 includes a rectangular frame, a support mesh fixedly connected to the inner side wall of the rectangular frame, an insertion groove opened on the outer side wall of the rectangular frame, a locking groove opened on the inner side wall of the insertion groove, a guide hole penetrating the side wall of the rectangular frame, and a locking groove opened on the top of the rectangular frame.

[0055] The flipping mechanism also includes guide rods 403 and rectangular frame 405 fixedly connected to the outer wall of the mounting plate 402. There are four guide rods 403, which are arranged in a rectangular array. The outer diameter of the guide rods 403 is equal to the inner diameter of the guide hole. By allowing the guide rods 403 to pass through the guide hole, the outer wall of the tray 404 abuts against the outer wall of the mounting plate 402. At this time, the opening of the rectangular frame 405 will be directly opposite the opening of the tray 404, and the bottom surface of the rectangular frame 405 will be in contact with the top surface of the tray 404.

[0056] The flipping mechanism also includes an electromagnet embedded inside the rectangular frame 405, a spring groove at the bottom of the rectangular frame 405, a connecting spring 406 fixedly connected to the bottom of the spring groove, and a locking block 407 fixedly connected to the end face of the connecting spring 406. The outer diameter of the locking block 407 is equal to the inner diameter of the locking groove. There are two sets of the overall structure consisting of the spring groove, the connecting spring 406, and the locking block 407. The two sets of overall structures are symmetrically arranged about the mid-section of the electromagnet. The locking block 407 is made of ferromagnetic material. When the electromagnet is energized and has magnetic force, it will attract the locking block 407, causing it to compress the connecting spring 406 until the locking block 407 is completely located inside the spring groove. When the electromagnet is de-energized and loses its magnetic force, the locking block 407 will extend to the outer surface of the spring groove at one end under the action of the connecting spring 406.

[0057] The flipping mechanism also includes a storage chamber 408 fixedly connected to the outer wall of the outer shell 1, an electric push rod 409 fixedly connected to the inner wall of the storage chamber 408, a transmission plate 4010 fixedly connected to the output end of the electric push rod 409, a storage groove opened on the outer wall of the transmission plate 4010, an electric telescopic rod 4011 fixedly connected to the inner wall of the storage groove, a locking rod 4012 fixedly connected to the output end of the electric telescopic rod 4011, and a limiting rod 4013 fixedly connected to the outer wall of the output end of the electric telescopic rod 4011.

[0058] There are two trays 404. One tray 404 is fixedly connected to the outer wall of the mounting plate 402, and the other tray 404 is fixedly connected to the outer wall of the transmission plate 4010. By fitting the insertion slot of one of the trays 404 into the transmission plate 4010 until the tray 404 can no longer be pushed, the storage slot will be aligned with the locking slot. Then, the electric telescopic rod 4011 is activated to extend, thereby inserting half of the locking rod 4012 into the inside of the locking slot, thus fixing the tray 404.

[0059] After the tea leaves have been dried for a period of time, the servo motor 301 is activated, which drives the transmission rod 302 to rotate until it rotates 90°, aligning the guide rod 403 with the guide hole of the other tray 404. Then, the electric push rod 409 is activated, which moves the other tray 404 toward the transmission rod 302. During this process, its electromagnet is energized, causing it to attract the locking block 407 and compress the connecting spring 406 until the locking block 407 is completely inside the spring groove. When the limiting rod 4013 abuts against the lower tray 404, the guide hole of the upper tray 404 will fit onto the outer surface of the guide rod 403, and the outer wall of the upper tray 404 will abut against the mounting... Plate 402 is then activated, followed by the extension and retraction of the electric telescopic rod 4011, which causes the locking rod 4012 to disengage from the locking groove. At this time, the electromagnet is de-energized, allowing the locking block 407 to be inserted into the locking groove, thus fixing the two trays 404. Then, the electric push rod 409 is activated, causing the transmission plate 4010 to disengage from the insertion groove. After that, the flipping motor 401 is activated, causing the mounting plate 402 to rotate 180°, thereby conveying the tea leaves from the lower tray 404 to the upper tray 404, thus flipping the tea leaves. After flipping, the transmission plate 4010 is reconnected to the tray 404 to remove the tray 404, ensuring the drying effect of the tea leaves.
