Description

Technical Field

[0001] This application relates to the technical field of tea processing, and specifically discloses a drying device for tea processing. Background Art

[0002] Tea usually contains a relatively high amount of moisture. If directly packaged or stored, it is prone to mildew and deterioration. Through drying treatment, the moisture in the tea can be effectively removed, reducing the moisture content of the tea to an appropriate range, thereby extending the shelf life of the tea and facilitating storage and transportation. At the same time, drying can fix the shape of the tea, maintaining its beauty and integrity, which is particularly important for some teas that need to maintain a specific shape, such as curly green tea, oolong tea, etc. Also, for some teas that do not undergo fermentation or only require slight fermentation, such as green tea, white tea, etc., drying can quickly terminate the activity of enzymes, preventing the tea from over-fermenting, and thus retaining the natural color, aroma, and taste of the tea.

[0003] In the drying of tea, for tea to be consumed in the short term, high-temperature and rapid drying is usually adopted; while for tea to be stored for a long time, low-temperature and slow drying is usually adopted to better retain the quality of the tea, maximizing the retention of the natural quality and characteristics of the tea, and being more suitable for some teas with higher quality requirements, delicate aroma, and taste.

[0004] Currently, low-temperature and slow drying of tea is mainly carried out through a drying furnace. Its basic process is: after placing the tea into the drying furnace through a material tray or the like, closing the furnace door to form a relatively sealed environment inside the drying furnace, and using a heat pump and a blower to supply heat to the drying furnace, thereby continuously evaporating the moisture in the tea. However, during this process, in order to ensure the uniformity of heat received by the tea, it is necessary to periodically turn the tea inside the drying furnace. During this process, it is necessary to open the furnace door of the drying furnace, which destroys the relatively sealed environment inside the drying furnace, resulting in heat energy overflow and causing energy waste, and also reducing the efficiency of drying the tea. Therefore, in view of this, the present invention provides a drying device for tea processing to solve the above problems. Summary of the Invention

[0005] The purpose of the present invention is to solve the problem that in traditional tea drying, it is necessary to open the furnace door of the drying furnace to turn the tea being dried, resulting in heat energy overflow and causing energy waste.

[0006] To achieve the above purpose, the basic solution of the present invention provides a drying device for tea processing, including:

[0007] A furnace body, with a furnace door provided on the side wall of the furnace body;

[0008] A heat energy component for supplying heat to the interior of the furnace body;

[0009] A load-bearing assembly arranged in the furnace body and capable of accommodating tea leaves, comprising a support frame arranged in the furnace body and a plurality of material trays rotatably connected to the support frame;

[0010] A toggling assembly arranged in the furnace body and used to toggle the tea leaves on the material tray comprises a power member arranged outside the furnace body, a plurality of dials driven by the power member and vertically slidably connected along the support frame, and a plurality of toggling rods respectively arranged on the dials and used to toggle the tea leaves in the material tray;

[0011] A drive assembly that drives each dial to move vertically.

[0012] The principles and effects of this basic solution are:

[0013] Compared with the prior art, the present invention not only supplies heat source to the inside of the furnace body through the thermal energy component to dry the tea leaves, but also drives the dial and the lever to rotate through the power part to turn the dried tea leaves, so that the tea leaves can be turned and dried without opening the furnace door, thereby ensuring the uniformity of heating the tea leaves, effectively maintaining a relatively closed environment inside the furnace body, avoiding the problem of energy waste caused by heat overflow, and improving the efficiency of tea drying.

[0014] Furthermore, the support frame includes columns symmetrically arranged in the furnace body and a plurality of connecting frames vertically arranged in sequence between the columns, so as to support a plurality of material trays.

[0015] Further, the driving assembly comprises:

[0016] Sliding plates are vertically slidably connected to the columns respectively;

[0017] A plurality of connecting lugs are arranged on the sliding plate, and the dial is rotatably connected to the connecting lugs;

[0018] The pushing mechanism pushes the sliding plate to slide along the column.

[0019] The pushing mechanism drives the sliding plate to slide vertically along the column, so as to drive the connecting ear piece on the column and the dial rotatably installed on the connecting ear piece to slide vertically along the column, thereby driving the dial, the lever, etc. away from or close to the material tray, thereby facilitating the placement and removal of the material tray and drying of the tea leaves in the material tray.

[0020] Furthermore, the driving mechanism comprises:

[0021] A push rod, horizontally slidably connected along the furnace body;

[0022] A pushing wedge block is connected to the push rod, and the bottom of the sliding plate is provided with an inclined surface adapted to the pushing wedge block;

[0023] A return spring is sleeved on the push rod and drives the push rod to return to its original position;

[0024] When the furnace door is closed, the furnace door presses the push rod, so that the sliding plate cooperates with the lowest part of the pushing wedge block. When the furnace door is opened, the return spring drives the push rod to reset, so that the sliding plate cooperates with the highest part of the pushing wedge block.

[0025] During the tea drying process, when the furnace door is in the open state, it is mainly used for the process of feeding and discharging tea; while when the furnace door is in the closed state, it is mainly used for the process of tea drying. Based on this characteristic, the opening and closing of the furnace door are used to drive the movement of the push rod, and then the pushing wedge block and the sliding plate cooperate with each other, and the elastic potential energy of the return spring drives the dial to move vertically, so that when the furnace door is in the open state, the dial, the dial rod, etc. are far away from the material tray, facilitating the feeding and discharging of tea; while when the furnace door is in the closed state, the dial, the dial rod, etc. are close to the material tray, facilitating the drying of the tea in the material tray.

[0026] Furthermore, an adjusting seat is provided at the bottom of the column inside the furnace body. An adjusting cavity is provided inside the adjusting seat. The pushing wedge block is slidably connected in the adjusting cavity. The push rod includes a first rod body and a second rod body respectively connected to the pushing wedge block. The return spring includes a first spring and a second spring respectively sleeved on the first rod body and the second rod body. When the furnace door is closed, the return spring is in a compressed state. This is to facilitate driving the push rod to move by using different states of the furnace door opening and closing, and after the furnace door is separated from the push rod, using the return spring to drive the push rod to reset. Furthermore, when the furnace door is in the open state, the dial, the dial rod, etc. are far away from the material tray, facilitating the feeding and discharging of tea; while when the furnace door is in the closed state, the dial, the dial rod, etc. are close to the material tray, facilitating the drying of the tea in the material tray.

[0027] Furthermore, a sleeve is provided on the sliding plate, a guide shaft slidably connected to the inside of the sleeve is provided on the column, and a third spring contacting the guide shaft is provided inside the sleeve. This is to facilitate driving the sliding plate to reset vertically.

[0028] Furthermore, the dial includes:

[0029] A rotating shaft;

[0030] A plurality of connecting rods provided on the side wall of the rotating shaft, and the dial rods are respectively arranged on each connecting rod in an alternating manner;

[0031] A connecting disk surrounding the end of the connecting rod and rotatably connected to the connecting ear piece.

[0032] This is to facilitate the rotation of the dial driven by the power component, and drive the connecting rod and the dial rod to rotate to turn the tea being dried in the material tray.

[0033] Further, arc grooves adapted to the connection disks are provided on the connection lugs. A height difference is formed between the side wall of the connection disk and the end of the connection rod, and the height difference is greater than the depth of the arc groove. The arc grooves on the connection lugs cooperate with the connection disks to facilitate the limitation of the rotation of the connection disks. Meanwhile, the connection disks and the dial can be driven to move vertically as a whole.

[0034] Further, connection shafts are provided at the top and bottom of the rotating shaft. A sleeve spline-connected to the connection shaft is rotatably connected to the support frame. This facilitates the disconnection or connection and synchronous rotation between two vertically adjacent rotating shafts, so as to facilitate the turning of the tea leaves on all the trays.

[0035] Based on the same inventive concept, the present invention discloses a drying method for tea processing, including drying tea using the above drying device, and comprising the following steps:

[0036] Step S1: After spreading the tea leaves flat on the trays, place the trays on the support frame in sequence;

[0037] Step S2: Close the furnace door, and the driving assembly drives the dial to move so that each dial rod contacts the tea leaves in each tray;

[0038] Step S3: Start the power component and the heat energy component. While supplying heat energy to the furnace body through the heat energy component to dry the tea leaves, the power component drives the dial and the dial rods to rotate to turn the tea leaves being dried;

[0039] Step S4: Turn off the power component and the heat energy component, open the furnace door, and the driving assembly drives the dial to move, and the dial rods move away from each tray;

[0040] Step S5: Take out the trays and collect the dried tea leaves in the trays.

[0041] This method can turn and dry the tea leaves without opening the furnace door, thereby ensuring the uniformity of the tea leaves' heat reception, effectively maintaining the relatively airtight environment inside the furnace body, avoiding the problem of heat energy overflow leading to energy waste, and also improving the efficiency of tea leaf drying.

[0054] The thermal energy component includes a heating pipe extending into the furnace body 1, a heat pump and a fan connected to the heating pipe. The air is filtered, sucked by the fan, and heated by the heat pump before entering the furnace body 1, so that an ambient temperature for drying tea leaves is formed inside the furnace body 1.

[0055] The bearing assembly includes a support frame arranged in the furnace body 1 and a plurality of material trays 4 rotatably connected to the support member, wherein Figure 3 and Figure 5 As shown, the support frame includes columns 5 symmetrically arranged in the furnace body 1 and a plurality of connecting frames 9 vertically arranged between the columns 5 in sequence. The connecting frames 9 and the columns 5 are fixed to each other to form a stable load-bearing structure for accommodating the placement of the material tray 4.

[0056] The toggle assembly includes a power member arranged on the outer side of the top of the furnace body 1, a plurality of dials driven by the power member and connected to the support frame by vertical sliding, and a plurality of levers 11 respectively arranged on the dials and used to toggle the tea leaves in the material tray 4. The power member is a motor 3 installed on the outer side of the top of the furnace body 1. The number of the dials corresponds to the number of the connecting frame 9. Figure 3 and Figure 5 As shown, the dial includes a rotating shaft 15 , three connecting rods 12 arranged on the side wall of the rotating shaft 15 , and a connecting disk 10 enclosed at the end of the connecting rod 12 , and each of the dial rods 11 is staggeredly arranged on each of the connecting rods 12 . A mounting cylinder 23 is provided in the middle of the support frame, and a sleeve 16 is rotatably installed on the mounting cylinder 23, and a retaining ring is installed at the bottom of the mounting cylinder 23 to prevent the sleeve 16 from detaching.

All the top connecting shafts 21 are always connected with the sleeve 16 above them and the output shaft of the motor 3, and all the bottom connecting shafts 22 can be detached or connected with the sleeve 16 below them and rotate synchronously. When all the bottom connecting shafts 22 are connected with the sleeve 16 below them, all the dials rotate synchronously under the drive of the motor 3 and the transmission of each sleeve 16. Correspondingly, an inner ring adapted to the mounting tube 23 and an outer ring located at the end of the material tray 4 are provided in the middle of the material tray 4 to prevent the tea leaves in the material tray 4 from scattering.

[0057] It also includes a driving assembly for driving each dial to move vertically, such asFigure 3 and Figure 5 As shown in Figure 5 , the driving assembly includes a sliding plate 13 that is vertically slidably connected to the column 5, a connecting lug 14 provided on the sliding plate 13, and a pushing mechanism for pushing the sliding plate 13 to slide vertically. Among them, a chute is provided inside the column 5, the sliding plate 13 is slidably connected in the chute, a limiting groove communicating with the chute is provided on the surface of the column 5, each connecting lug 14 is slidably connected to the limiting groove, and the surface of the column 5 between adjacent limiting grooves is used for connecting with the connecting frame 9. As Figure 6 shown in Figure 6 , the connecting lug 14 is formed by closing two symmetrically arranged lugs, and the two lugs are closed to form an arc groove adapted to the connecting disk 10 to limit the rotation of the connecting disk 10 and drive the connecting disk 10 to move vertically. In order to prevent the connecting rod 12 from interfering with the cooperation between the connecting disk 10 and the connecting lug 14, the thickness of the connecting rod 12 is less than the thickness of the connecting disk 10, so that a height difference is formed between the side wall of the connecting disk 10 and the end of the connecting rod 12, and the height difference is greater than the depth of the arc groove.

[0058] As Figure 4 shown in Figure 4 , an adjusting seat 6 is provided at the bottom of each column 5. An adjusting cavity is provided inside the adjusting seat 6. The pushing mechanism includes a pushing wedge 18 that is horizontally slidably connected in the adjusting seat 6, a push rod connected to the pushing wedge 18, and a return spring for driving the push rod and the pushing wedge 18 to reset. Among them, the side of the pushing wedge 18 close to the furnace door 2 is at a low position, and the side away from the furnace door 2 is at a high position. The bottom of the sliding plate 13 extends into the adjusting cavity and is provided with an inclined surface 17 adapted to the pushing wedge 18, so as to drive the sliding plate 13 to move vertically when the pushing wedge 18 moves horizontally; correspondingly, the push rod includes a first rod body 7 and a second rod body 20 respectively connected to the pushing wedge 18. The first rod body 7 passes through the front side of the adjusting seat 6 and is provided with a front side limiting ring, and the second rod body 20 passes through the rear side of the adjusting seat 6 and is provided with a rear side limiting ring. The return spring includes a first spring 8 sleeved on the first rod body 7 and located between the front side limiting ring and the adjusting seat 6, and a second spring 19 sleeved on the second rod body 20 and located between the pushing wedge 18 and the inner wall of the adjusting cavity, so as to drive the pushing wedge 18 to move horizontally and reset. It is convenient to drive the sliding plate 13 to reset vertically. As Figure 7 shown in Figure 7 , a sleeve 24 is provided on the sliding plate 13, a guide shaft 25 slidably connected to the inside of the sleeve 24 is provided on the column 5, and a third spring 26 in contact with the guide shaft 25 is provided inside the sleeve 24.

[0059] During the tea drying process, when the furnace door 2 is in the open state, it is mainly used for the process of loading and unloading tea; while when the furnace door 2 is in the closed state, it is mainly used for the tea drying process; the opening and closing of the furnace door 2 are used to drive the push rod to move, and then the pushing wedge block 18 and the sliding plate 13 cooperate with each other, and the elastic potential energy of the return spring is used to drive the dial to move vertically, so that when the furnace door 2 is in the open state, the dial, the dial rod 11, etc. are far away from the material tray 4, facilitating the loading and unloading of tea; while when the furnace door 2 is in the closed state, the dial, the dial rod 11, etc. are close to the material tray 4, facilitating the drying of the tea in the material tray 4.

[0060] Based on the same inventive concept, this embodiment also discloses a drying method for tea processing, including using the above drying device to dry tea, which includes the following steps:

[0061] Step S1, open the furnace door 2. At this time, the sliding plate 13 cooperates with the highest point of the pushing wedge block 18, and each bottom connecting shaft 22 is separated from the sleeve 16 below it to form a gap through which the material tray 4 can pass. After the operator spreads the tea evenly on the material tray 4, the material tray 4 is placed on the support frame in sequence;

[0062] Step S2, the staff closes the furnace door 2. The furnace door 2 squeezes the first rod body 7 of the push rod, causing the pushing wedge block 18 to move in the adjustment cavity. Under the action of the elastic potential energy of the third spring 26 and the gravity of the sliding plate 13, the sliding plate 13 gradually cooperates with the lowest point of the pushing wedge block 18, and each bottom connecting shaft 22 extends into the sleeve 16 below it and is connected with each other by splines, driving each dial rod 11 to contact the tea in each material tray 4;

[0063] Step S3, turn on the power component and the heat energy component. While supplying heat energy to the furnace body 1 through the heat energy component to dry the tea, the power component is also used to drive the dial and the dial rod 11 to rotate to turn over the tea being dried;

[0064] Step S4, turn off the power component and the heat energy component, and open the furnace door 2. The first spring 8 and the second spring 19 drive the pushing wedge block 18 to reset, and then the sliding plate 13 cooperates with the highest point of the pushing wedge block 18 again, and each bottom connecting shaft 22 is separated from the sleeve 16 below it to form a gap through which the material tray 4 can pass, that is, the dial rod 11 is far away from each material tray 4;

[0065] Step S5, the operator takes out the material tray 4 and collects the dried tea in the material tray 4.

[0066] While supplying heat source to the inside of the furnace body 1 through the heat energy component to dry the tea leaves, the power component is also used to drive the dial and the dial rod 11 to rotate, so as to turn the tea leaves being dried, thereby turning and drying the tea leaves without opening the furnace door 2, further ensuring the uniformity of the tea leaves' heat reception, effectively maintaining the relatively airtight environment inside the furnace body 1, avoiding the problem of energy waste caused by heat energy overflow, and also improving the efficiency of tea leaf drying.

[0067] The above are only the preferred embodiments of the present invention, and do not impose any form of limitation on the present invention. Although the present invention has been disclosed above with the preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some changes or modifications to equivalent embodiments by using the disclosed technical content within the scope of the technical solution of the present invention.
