Description

Technical Field

[0001] The invention relates to the technical field of tea processing, in particular to a withering device and a withering method for berry tea. Background Art

[0002] Berry tea belongs to the woody vine plant of the genus Agave in the family Vitaceae. During the processing of berry tea, due to the special vine-like plant morphology of berry tea, it is easy to accumulate and entangle during the withering process. The uneven heating of berry tea not only affects the withering effect, but also reduces the withering efficiency. The withering equipment in the prior art usually adopts a drum. During the heating process of the tea leaves, the rolling of the drum is used to drive the tea leaves to be stir-fried to evaporate the moisture in the tea leaves. At the same time, spiral blades are arranged in the drum to stir-fry the tea leaves according to their trajectory. However, the withering equipment in the prior art is mostly used for green tea, and is not suitable for berry tea with a special plant morphology, so it cannot solve the above technical problems. Summary of the invention

[0003] One purpose of the present invention is to reduce the accumulation of berry tea during the withering process, improve the heating uniformity of the berry tea, thereby improving the withering effect and improving the withering efficiency.

[0004] Another purpose of the present invention is to reduce the risk of entanglement of berry tea during the withering process, and further improve the uniformity of heating of berry tea during the withering process, thereby improving the withering effect and improving the withering efficiency.

[0005] In particular, the present invention provides a device for withering berry tea, comprising: a base; a heating shaft, rotatably arranged on the base and horizontally arranged along its axis; a plurality of spiral first fences are arranged on the outer wall surface of the heating shaft; a heating sleeve, arranged on the outer ring of the heating shaft and coaxially arranged with the heating shaft; the heating sleeve comprises an outer cylinder and a rotatable inner cylinder, and a plurality of spiral second fences are arranged on the side wall surface of the inner cylinder facing the heating shaft; in the axial direction of the heating shaft, the bars of the second fence are staggered with the bars of the first fence; the heating shaft and the inner cylinder are configured to rotate in the same direction but at different speeds; when the heating shaft and the inner cylinder rotate relative to each other, part of the bars of the first fence pass through the gaps between the bars of the second fence.

[0006] Furthermore, a first transmission gear is sleeved on the heating shaft; gear teeth are arranged on the side wall surface of the inner cylinder facing the heating shaft; a second transmission gear and a third transmission gear meshing with each other are arranged between the heating shaft and the inner cylinder; and the first transmission gear meshes with the second transmission gear, and the third transmission gear meshes with the gear teeth.

[0007] Furthermore, the spiral directions of the first fence and the second fence are opposite.

[0008] Furthermore, a feed port and a discharge port are respectively provided at both ends of the heating sleeve; the pitch of the first fence and the second fence gradually increases from one end close to the feed port to the other end close to the discharge port.

[0009] Further, the first fence is configured to be made of elastic material.

[0010] Furthermore, the equipment for withering berry tea also includes: a power device, which is arranged on the base and connected to the heating shaft.

[0011] Furthermore, a cavity is formed inside the heating shaft; an annular chamber is formed between the inner cylinder and the outer cylinder; hot steam is passed through the cavity and the annular chamber or a heating device is provided.

[0012] In particular, the present invention also provides a method for withering berry tea, which uses any of the above-mentioned withering equipment to wither the berry tea, including: controlling the rotation of a heating shaft and an inner cylinder in a heating sleeve sleeved on the heating shaft; controlling the heating shaft and the heating sleeve for heating; placing the berry tea to be withered between the heating shaft and the inner cylinder, and using a first fence on the heating shaft and a second fence on the inner cylinder to transport the berry tea from one end of the heating shaft to the other end and complete the withering; and taking out the withered berry tea.

[0013] The beneficial effects of the present invention are:

[0014] The device for fixing the berry tea of ​​the present invention heats the berry tea from both the inner and outer directions by arranging a coaxially sleeved heating shaft and a heating sleeve, thereby improving the heating uniformity of the berry tea and improving the fixing efficiency. By arranging a plurality of spiral first fences on the heating shaft and a plurality of spiral second fences on the inner cylinder of the heating sleeve, the rotation of the heating shaft and the inner cylinder drives the first fence and the second fence to rotate, so that the first fence and the second fence jointly break up and turn over the berry tea, thereby reducing the accumulation of the berry tea, improving the heating uniformity of the berry tea, and further improving the fixing effect. The bars of the first fence and the second fence are staggered in the axial direction, so that after the berry tea is lifted and slid down driven by the bars of the second fence, it can just fall on the bars of the first fence, and is further broken up driven by the bars of the first fence, thereby improving the heating uniformity of the berry tea.

[0015] Furthermore, the device for fixing the berry tea of ​​the present invention configures the heating shaft and the inner cylinder to rotate in the same direction but at different speeds, so that there is relative rotation between the heating shaft and the inner cylinder. The first fence and the second fence rotate relative to each other, further improving the turning effect of the first fence and the second fence on the berry tea, thereby improving the fixing uniformity of the berry tea.

[0016] Furthermore, in the device for fixing the berry tea of ​​the present invention, when the heating shaft and the inner cylinder rotate relative to each other, part of the bars of the first fence pass through the gaps between the bars of the second fence, so that part of the bars of the first fence can cross and move with the bars of the second fence, thereby separating the berry tea accumulated and entangled on the first fence and the second fence, thereby making the fixing of the berry tea more uniform. When only part of the bars of the first fence pass through the gaps between the bars of the second fence, the entanglement of the berry tea is reduced, and when the bars of the first fence and the bars of the second fence cross, the turning space of the berry tea is not restricted, thereby ensuring the turning effect of the berry tea.

[0017] The withering method for berry tea of ​​the present invention is applied to the above-mentioned withering equipment for berry tea, and thus the beneficial technical effects of the above-mentioned withering equipment for berry tea are also possessed by the withering method for berry tea of ​​the present invention.

[0036] This embodiment firstly provides a device for withering berry tea, which can generally include: a base 100 , a heating shaft 200 , and a heating sleeve 300 .

[0037] The heating shaft 200 is rotatably disposed on the base 100 and is horizontally disposed along its axis. A plurality of spiral first fences 210 are disposed on the outer wall surface of the heating shaft 200. The heating sleeve 300 is disposed on the outer ring of the heating shaft 200 and is coaxially disposed with the heating shaft 200. The heating sleeve 300 generally may include an outer cylinder 310 and a rotatable inner cylinder 320, and a plurality of spiral second fences 321 are disposed on the side wall surface of the inner cylinder 320 facing the heating shaft 200. In the axial direction of the heating shaft 200, the bars of the second fence 321 are staggered with the bars of the first fence 210. The heating shaft 200 and the inner cylinder 320 are configured to rotate in the same direction but at different speeds. When the heating shaft 200 and the inner cylinder 320 rotate relative to each other, some of the bars of the first fence 210 pass through the gaps between the bars of the second fence 321.

[0038] The solution of this embodiment is to set up a coaxial heating shaft 200 and a heating sleeve 300, and utilize the heating shaft 200 and the heating sleeve 300 to heat the berry tea from both the inside and the outside directions at the same time, so that the heat distribution between the heating shaft 200 and the heating sleeve 300 is more uniform, thereby improving the heating uniformity of the berry tea, thereby improving the withering effect, and further improving the withering efficiency.

[0039] The solution of this embodiment is to set a plurality of spiral first gratings 210 on the heating shaft 200, and set a plurality of spiral second gratings 321 on the inner cylinder 320 of the heating sleeve 300, and use the first gratings 210 and the second gratings 321 to jointly break up and turn over the berry tea, thereby reducing the accumulation of the berry tea, improving the uniformity of heating the berry tea, and further improving the effect of withering. The bars of the first gratings 210 and the second gratings 321 are staggered in the axial direction, so that the berry tea can fall on the bars of the first grating 210 after it rises and slides driven by the bars of the second grating 321. The berry tea is further broken up driven by the bars of the first grating 210, thereby improving its uniformity of heating.

[0040] Furthermore, in the solution of this embodiment, the heating shaft 200 and the inner cylinder 320 are configured to rotate in the same direction, so that after the second fence 321 drives the berry tea to rotate from one side and rise to a certain degree, the berry tea slides off the second fence 321 and flips, then falls on the first fence 210, and then flips to the other side of the heating sleeve 300 under the same direction of the first fence 210, which not only improves the flipping effect of the berry tea, but also improves the space utilization rate in the heating sleeve 300 and improves the tea-killing efficiency. The heating shaft 200 and the inner cylinder 320 are configured to rotate at different speeds, so that there is relative rotation between the heating shaft 200 and the inner cylinder 320. The first fence 210 and the second fence 321 rotate relative to each other, further improving the flipping effect of the first fence 210 and the second fence 321 on the berry tea, thereby improving the tea-killing uniformity.

[0041] Furthermore, in the solution of this embodiment, when the heating shaft 200 and the inner cylinder 320 rotate relative to each other, part of the bars of the first fence 210 pass through the gaps between the bars of the second fence 321, so that part of the bars of the first fence 210 can cross and move with the bars of the second fence 321, thereby separating the berry tea accumulated and entangled on the first fence 210 and the second fence 321, and further making the withering of the berry tea more uniform. Only part of the bars of the first fence 210 pass through the gaps between the bars of the second fence 321, which reduces the entanglement of the berry tea and ensures that when the bars of the first fence 210 and the bars of the second fence cross, the turning space of the berry tea is not restricted, thereby ensuring the turning effect of the berry tea.

[0042] In some embodiments, the first fence 210 may be a whole long fence extending spirally from one end of the heating shaft 200 to the other end; the second fence 321 may be a whole long fence extending spirally from one end of the inner cylinder 320 to the other end. In other embodiments, the first fence 210 and the second fence 321 may be configured as short fences with a shorter length. A plurality of first fences 210 are evenly spaced along the axial and circumferential directions of the heating shaft 200, and a plurality of second fences 321 are evenly spaced along the axial and circumferential directions of the inner cylinder 320. In some preferred embodiments, in the circumferential direction, every two adjacent first fences 210 or every two adjacent second fences 321 are parallel to each other, and the number of first fences 210 and second fences 321 may be equal.

[0043] The bars of the first fence 210 and the second fence 321 are staggered in the axial direction, which ensures that the first fence 210 and the second fence 321 do not interfere with each other, thereby ensuring the normal operation of the fixing equipment.

[0044] In some preferred embodiments, from the axial direction of the heating shaft 200, the outer edges of the plurality of first fences 210 on the heating shaft 200 are in a cam shape as a whole, so that when the heating shaft 200 rotates one circle relative to the inner cylinder 320, only part of the bars on the first fence 210 intersect with the second fence 321, and only intersect with each second fence 321 once, thereby reducing the frequency of intersection between the first fence 210 and the second fence 321, and avoiding the first fence 210 and the second fence 321 from intersecting and moving too frequently, thereby damaging the berry tea. In addition, only part of the bars on the first fence 210 intersect with the second fence 321, that is, there is a gap between the remaining bars on the first fence 210 and the second fence 321, so that the berry tea is not confined to the space between two adjacent first fences 210 or second fences 321, and can be turned over in the entire circumference of the inner cylinder 320 through the gap, thereby ensuring the killing effect and killing efficiency.

[0045] The heating shaft 200 is sleeved with a first transmission gear 220. The inner cylinder 320 of the heating sleeve 300 is provided with gear teeth 322 on the side wall surface facing the heating shaft 200. A second transmission gear 330 and a third transmission gear 340 meshing with each other are provided between the heating shaft 200 and the inner cylinder 320. The first transmission gear 220 meshes with the second transmission gear 330, and the third transmission gear 340 meshes with the gear teeth 322.

[0046] The solution of this embodiment utilizes gear transmission to link the rotation of the heating shaft 200 and the rotation of the inner cylinder 320, and has a simple and delicate structure and is easy to install.

[0047] In some embodiments, the first transmission gear 220 can be sleeved on the end of the heating shaft 200, and the gear teeth 322 on the inner cylinder 320 can be correspondingly arranged on the end of its side wall surface. The second transmission gear 330 and the third transmission gear 340 can be arranged on the end wall of the heating sleeve 300, so as to achieve the transmission effect while reducing the interference with the withering of the berry tea.

[0048] In some preferred embodiments, a first transmission gear 220 may be provided at both ends of the heating shaft 200, gear teeth 322 may be provided at both ends of the inner cylinder 320, and a second transmission gear 330 and a third transmission gear 340 may be provided on both end walls of the heating sleeve 300 to further improve the transmission effect and structural stability.

[0049] In some embodiments, the first transmission gear 220 may be integrally formed with the heating shaft 200. In other embodiments, the heating shaft 200 may not be sleeved with the first transmission gear 220, and the end of the outer wall of the heating shaft 200 may be directly formed with transmission teeth meshing with the second transmission gear 330.

[0050] The spiral directions of the first fence 210 and the second fence 321 are opposite.

[0051] In the solution of this embodiment, the spiral direction of the first fence 210 is set to be opposite to the spiral direction of the second fence 321, so that when the bars of the second fence 321 intersect with the first fence 210, the bars of the second fence 321 sequentially pass through the gaps between the bars of the first fence 210, so that the intersection of the second fence 321 and the first fence 210 is smoother. In addition, because the spiral direction of the first fence 210 is opposite to that of the second fence 321, the berry tea will flow back a certain distance in the axial direction under the drive of the first fence 210, thereby increasing the retention time of the berry tea in the inner cylinder 320, thereby ensuring the effect of withering.

[0052] The heating sleeve 300 is also provided with a feed port 350 and a discharge port 360 at both ends. The pitch of the first fence 210 and the second fence 321 gradually increases from one end close to the feed port 350 to the other end close to the discharge port 360.

[0053] When the berry tea is just placed into the inner cylinder 320 through the feed port 350, the water content of the berry tea is the highest and the required heating amount is the largest. As the berry tea is gradually transported from the feed port 350 to the discharge port 360, the water content of the berry tea gradually decreases and the required heating amount gradually decreases.

[0054] In the solution of the present embodiment, the pitch of the first fence 210 and the second fence 321 is set to be larger from the feed port 350 to the discharge port 360, so that the transportation speed of the berry tea is faster and faster from the discharge port 360 to the discharge port 360, and the gradually decreasing heating time is adapted to the continuously decreasing water content of the berry tea, thereby improving the withering efficiency while ensuring the withering effect.

[0055] The first fence 210 is configured to be made of an elastic material.

[0056] When the berry tea is tightly wound, pulling it apart forcibly may cause damage to the leaves of the berry tea.

[0057] In the solution of this embodiment, the first fence 210 is configured to be made of an elastic material, so that when the bars of the first fence 210 intersect with the second fence 321, when the bars of the first fence 210 pass through the gaps between the bars of the second fence 321, the bars of the first fence 210 can be elastically deformed, slowly pulling apart the entangled berry tea, thereby reducing the risk of damage to the leaves. In addition, the first fence 210 made of elastic material itself is not easy to entangle the berry tea, reducing the risk of the berry tea entangled on the first fence 210.

[0058] The equipment for withering berry tea may generally further include a power device 400 .

[0059] The power device 400 is disposed on the base 100 and connected to the heating shaft 200 .

[0060] In the solution of this embodiment, the power device 400 is started to drive the heating shaft 200 to rotate, and the heating shaft 200 drives the inner cylinder 320 to rotate through the first transmission gear 220, the second transmission gear 330, the third transmission gear 340 and the gear teeth 322.

[0061] like Figure 1 , 3As shown, in some embodiments, a first transmission wheel 110 may be further provided on the base 100, and a second transmission wheel 120 may be provided at the end of the heating shaft 200. The shaft of the first transmission wheel 110 is connected to the power device 400, and the first transmission wheel 110 and the second transmission wheel 120 are connected to each other through a transmission chain 130. By starting the power device 400, the first transmission wheel 110 and the second transmission wheel 120 are driven to rotate, thereby driving the heating shaft 200 and the inner cylinder 320 in the heating sleeve 300 to rotate.

[0062] In some embodiments, the power device 400 may include structures such as a motor and a reducer.

[0063] A cavity 230 is formed inside the heating shaft 200, and an annular chamber 370 is formed between the inner cylinder 320 and the outer cylinder 310. Hot steam or a heating device is provided in the cavity 230 and the annular chamber 370.

[0064] In some embodiments, hot steam is passed through the annular chamber 370 of the heating sleeve 300 to heat the inner cylinder 320, thereby heating the berry tea in the inner cylinder 320. Hot steam may be passed through the interior of the heating shaft 200, and a plurality of vents may be formed on the side wall surface of the heating shaft 200 to pass the hot steam into the inner cylinder 320 to heat the berry tea.

[0065] In other embodiments, a heating device, such as a heating wire, may be disposed inside the heating shaft 200 and the annular chamber 370 of the heating sleeve 300. The heat dissipated by the heating device is used to heat and sterilize the berry tea.

[0066] In some embodiments, the size of the vent holes on the heating shaft 200 is configured to be particularly small to prevent berry tea from falling into the vent holes. In other embodiments, the size of the vent holes on the heating shaft 200 can be configured to be larger to improve the heat transfer efficiency, and a cover net can be provided on the vent holes to prevent berry tea from falling into them.

[0067] The specific working process of the device for fixing berry tea provided by the present invention is described in combination with the above embodiments:

[0068] The power device 400 drives the heating shaft 200 to rotate, and then drives the inner cylinder 320 of the heating sleeve 300 to rotate through the first transmission gear 220 and the second transmission gear 330. The heating shaft 200 and the inner cylinder 320 rotate in the same direction but at different speeds. During the rotation of the heating shaft 200 and the inner cylinder 320, the heating shaft 200 and the heating sleeve 300 heat the space between the inner cylinder 320 and the heating shaft 200.

[0069] The berry tea is placed between the inner cylinder 320 and the heating shaft 200 through the feed port 350. The inner cylinder 320 rotates, and the berry tea moves toward the discharge port 360 driven by the second fence 321. In this process, the berry tea is repeatedly raised and then dropped driven by the second fence 321. The berry tea rolls down onto the first fence 210 of the heating shaft 200, and is turned over and moved back to the feed port 350 for a distance driven by the first fence 210 to extend the residence time of the berry tea in the inner cylinder 320. During the relative rotation of the first fence 210 and the second fence 321, some bars of the first fence 210 pass through the gaps between the bars of the second fence 321 to break up the accumulated and entangled berry tea. The berry tea is transported to the discharge port 360 and is withered, and then discharged from the discharge port 360.

[0070] Figure 8 The figure is a schematic flow chart of a method for withering berry tea according to an embodiment of the present invention.

[0071] like Figure 8 As shown, this embodiment also specifically provides a method for killing green tea of ​​berry tea, using any of the above-mentioned killing green equipment to kill green tea of ​​berry tea. The method for killing green tea of ​​berry tea generally can include:

[0072] Step S802 , controlling the heating shaft 200 and the inner cylinder 320 of the heating sleeve 300 sleeved on the heating shaft 200 to rotate.

[0073] Step S804, controlling the heating shaft 200 and the heating sleeve 300 to perform heating.

[0074] Step S806, placing the berry tea to be withered between the heating shaft 200 and the inner cylinder 320, using the first fence 210 on the heating shaft 200 and the second fence 321 on the inner cylinder 320 to transport the berry tea from one end of the heating shaft 200 to the other end and complete the withering.

[0075] Step S808, after waiting for the withering to be completed, take out the berry tea.

[0076] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0077] The above-described embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention.
