Description

Technical Field

[0001] The invention belongs to the technical field of tea withering, in particular to tea withering equipment and a withering method thereof. Background Art

[0002] Tea withering equipment is a mechanical device that uses specific technical principles to control temperature, humidity, ventilation and other conditions to wither tea in a suitable environment. Its main function is to achieve a suitable state of tea through scientific withering treatment, which is convenient for subsequent rolling, fermentation and other processes, thereby improving the quality and taste of tea. In the processing of tea, withering is an important processing link, which can effectively improve the quality of tea.

[0003] Conventional tea withering devices mainly achieve the withering of tea by strictly controlling the water content inside the tea leaves. The existing technology mainly uses two methods to achieve the withering operation of tea leaves: hot air drying and natural drying. No matter which withering method is used, the tea leaves need to be spread flat on the withering trough for withering. At the same time, since the tea leaves are basically in a one-sided heating state during withering, they need to be turned frequently during the withering process, which seriously affects the withering efficiency of the tea leaves.

[0004] When withering tea leaves, in order to improve the quality of the tea leaves, the tea leaves are usually withered repeatedly. When withering is performed in a withering trough in the prior art, the tea leaves on the withering trough need to be manually shoveled out after each withering, and then laid flat on the top of the withering trough after cooling. This process requires repeated collection, laying and transportation of the tea leaves, and there are many operating steps, which seriously affects the withering efficiency. Summary of the invention

[0005] The object of the present invention is to provide a tea withering device and a tea withering method thereof to solve the problems raised in the above background technology.

[0006] In order to achieve the above-mentioned purpose, the present invention provides the following technical solutions: a tea withering device, including a withering box assembly, a lifting conveyor belt is provided on the right side of the withering box assembly, the lifting conveyor belt is in a Z-shape, a baffle plate is installed on the outer surface of the lifting conveyor belt, a frame is installed on the outer side of the lifting conveyor belt, the lifting conveyor belt and the frame are movably connected, an extension base is installed on the side of the frame close to the withering box assembly, the extension base is connected to the withering box assembly, auxiliary withering components are provided on the front and back sides of the inner cavity of the withering box assembly, and the withering box assembly is provided with a lifting conveyor belt. Fixed guide rails are installed on both the front and rear sides of the bottom end of the withering box assembly, and bottom plates are provided on both the front and rear sides between the two fixed guide rails. The left and right sides of the bottom plate are movably connected with the two fixed guide rails, and the bottom plate is displaced forward and backward relative to the fixed guide rails. An auxiliary discharging assembly is installed on the bottom end of the bottom plate, and the top end of the auxiliary discharging assembly is connected to the auxiliary withering assembly. The auxiliary withering assembly and the auxiliary discharging assembly are both arranged diagonally. A gas hose is installed on one end of the auxiliary discharging assembly close to the withering box assembly, and the other end of the gas hose is connected to the withering box assembly.

[0007] The withering box assembly includes a withering box body, and hot air boxes are fixedly installed on the left and right sides of the withering box body near the top, and hot air pipes are installed on the left and right sides of the inner side of the withering box body near the top, and the hot air pipes are connected to the hot air boxes, and the left and right sides of the bottom end of the withering box body are connected to the fixed guide rails, and the side of the withering box body is connected to the extension base. A three-way valve is provided under the hot air box, and the front and rear ends of the three-way valve are connected to the front and rear ends of the hot air box, and the bottom end of the three-way valve is connected to the other end of the air supply hose, and the front and rear sides of the top of the withering box body are installed with extension mounting frames, and the extension mounting frames are movably connected to the auxiliary withering assembly.

[0008] Before withering the tea leaves, the tea leaves to be withered can be put into the withering box body, and the auxiliary discharging component can be connected to the external hot air blower, while ensuring that the input pressure meets the requirements. At the same time, an operator for transporting the tea leaves is set at the right end of the lifting conveyor belt to complete the preparations before withering. At the same time, a baffle must be installed on the outer surface of the lifting conveyor belt to prevent the tea leaves from falling, ensuring that the tea leaves can be lifted correctly.

[0009] As a further technical solution of the present invention, the auxiliary discharging assembly includes a power tank, and a locking frame is installed on the outer side of the power tank. The locking frame is connected to one side of the withering box body, and the two locking frames are diagonally symmetrically installed on the left and right sides of the withering box body.

[0010] As a further technical solution of the present invention, one end of the locking frame away from the withering box assembly is fixedly connected to an air intake valve, and the air intake valve is connected to an external hot air blower. One end of the power tank close to the withering box assembly is fixedly connected to an exhaust valve, and the other end of the exhaust valve is connected to a gas hose.

[0011] As a further technical solution of the present invention, a main shaft is movably connected to the middle of the power tank, and the main shaft rotates relative to the power tank. The outer side of the main shaft is fixedly sleeved with an impeller inside the power tank, and the top of the power tank is connected to the auxiliary withering component.

[0012] When it is necessary to wither the tea leaves, the hot air can be introduced into the interior of the air inlet valve by turning on the external hot air blower. At this time, the hot air can be introduced into the interior of the air supply hose through the power tank and the exhaust valve, and is transported into the interior of the three-way valve through the air supply hose, and is distributed into the interior of the hot air box through the left and right ends of the three-way valve, and is finally discharged through the hot air duct. At this time, the tea leaves fall vertically from the top of the withering box body to the bottom of the withering box body, and the tea leaves are fully in contact with the hot air, completing the initial withering process.

[0013] At the same time, when the hot air enters the power tank, it can drive the impeller to rotate. At this time, the main shaft rotates accordingly and transmits power to the auxiliary withering component.

[0014] By utilizing the hot air required for withering and changing the traditional flat withering method to allowing the tea leaves to fall freely and contact them with hot air, the tea leaves do not need to be turned over manually during withering, which can significantly increase the contact area between the tea leaves and the hot air, thereby increasing the withering speed of the tea leaves, allowing them to quickly dry out moisture and improving the withering efficiency of the tea leaves.

[0015] As a further technical solution of the present invention, the auxiliary withering component includes a mounting shaft located inside the withering box body, a first transmission shaft is fixedly installed on the top end of the mounting shaft, the top end of the first transmission shaft is movably connected to the extended mounting frame, the first transmission shaft rotates relative to the extended mounting frame, and a disturbance disk is fixedly sleeved on the outer side surface of the mounting shaft at equal distances.

[0016] As a further technical solution of the present invention, a synchronous belt is movably connected to the outer side of the first transmission shaft, and a second transmission shaft is movably connected to the other end of the synchronous belt. The first transmission shaft is connected to the second transmission shaft through the synchronous belt, and an extension shaft is fixedly connected to the bottom end of the second transmission shaft, and the bottom end of the extension shaft is connected to the top of the main shaft.

[0017] At the same time, during the falling process of the tea leaves, the rapid rotation of the main shaft can drive the synchronous rotation of the extension shaft. At this time, the second transmission shaft rotates accordingly, and drives the first transmission shaft to rotate through the synchronous belt until the installation shaft is driven to rotate rapidly. At the same time, the disturbance disk on the outer side of the installation shaft rotates synchronously to stir the tea leaves falling freely inside the withering box body, causing the tea leaves to tumble to a certain extent, avoiding the tea leaves from piling up and falling, and assisting in completing the withering process.

[0018] By further utilizing the hot air required for withering tea leaves, the flow of hot air can provide a heat source for withering tea leaves, and the flow power can be converted into power for rotating the mounting shaft to further stir the tea leaves, causing the tea leaves to tumble automatically. At the same time, the tumbling speed is positively correlated with the hot air input speed, thereby further increasing the contact time between the tea leaves and the hot air, and further improving the tea withering efficiency.

[0019] As a further technical solution of the present invention, the bottom end of the main shaft passes through the bottom end of the power tank and is fixedly connected to a first connecting rod, and one end of the first connecting rod away from the main shaft is movably connected to a second connecting rod through a rotating shaft.

[0020] As a further technical solution of the present invention, one end of the second connecting rod away from the first connecting rod is movably connected to a mounting seat through a rotating shaft, and the mounting seat is respectively connected to the middle part of the bottom end of the two base plates, the mounting seat on the right side is connected to the base plate at the front end, and the mounting seat on the left side is connected to the base plate at the rear end.

[0021] As the withering progresses and the tea leaves are put in, the tea leaves can fall automatically. At the same time, when the main shaft rotates, the first connecting rod rotates synchronously and drives the second connecting rod to swing. At this time, the mounting seat is subjected to forward pulling force and backward pushing force, and the bottom plate is subjected to corresponding pulling force and pushing force. The two bottom plates can be relatively close or relatively far away through two sets of symmetrically arranged auxiliary discharging components. When the two bottom plates are relatively far away, the channel at the bottom of the withering box body can be opened to discharge the tea leaves. Through the regular reciprocating motion of the two bottom plates, the tea leaves can be regularly discharged and fall onto the surface of the lifting conveyor belt. As the lifting conveyor belt is transported and lifted, the tea leaves can be transported in sections. The repeated withering process can be completed by putting the tea leaves into the withering box body again until the withering quality requirements are met.

[0022] By making full use of the air required for withering tea leaves, and converting the flow of air into rotational power, the rotational power can also be converted into reciprocating power, thereby realizing the reciprocating motion of the bottom plate and the regular opening of the bottom end of the withering box body, that is, realizing automatic and regular discharge of tea leaves, completing automatic discharge, and at the same time automatically cooling the tea leaves through the lifting process of the lifting conveyor belt, and after simple collection, secondary withering can be carried out, which significantly shortens the preparation time for repeated withering and improves the withering quality.

[0023] A withering method for tea withering equipment, comprising the following steps:

[0024] S1: Before use, the external hot air blower can be connected to the two auxiliary discharging components, and a certain hot air input pressure can be maintained. The tea leaves to be withered are put into the withering box through the top of the withering box body, and the lifting conveyor belt is turned on. At the same time, an operator needs to be arranged at the right end of the lifting conveyor belt to transfer the tea leaves at the rightmost end of the lifting conveyor belt surface to the withering box body to complete the preparation before withering;

[0025] S2: At this time, the tea leaves can enter the interior of the withering box body by gravity. When the tea leaves enter, the external hot air blower can enter the interior of the power tank and be discharged through the exhaust valve and the air hose, and then through the three-way valve and the hot air box, and finally ejected through the hot air pipe, at this time, the falling tea leaves can be heated and dried;

[0026] S3: When the hot air enters the power tank, it can drive the impeller to rotate. At this time, the main shaft rotates accordingly, driving the extension shaft to rotate, and finally driving the disturbance disk to rotate. At this time, the tea leaves entering the withering box body can be stirred, and the hot air can be disturbed to increase the contact area between the hot air and the tea leaves, completing the auxiliary withering process;

[0027] S4: When the main shaft rotates, it can drive the first connecting rod and the second connecting rod to swing, and finally drive the two bottom plates to move closer or farther away from each other. When the two bottom plates move away from each other, the passage at the bottom of the withering box body can be opened, and the tea leaves can be discharged from the bottom of the withering box body regularly and fall onto the surface of the lifting conveyor belt in a quantitative manner.

[0028] S5: At this time, the conveyor belt can be lifted to lift the quantitatively fallen tea leaves to a higher place. At this time, the operator can collect the quantitative tea leaves and put them back into the withering box body for secondary withering, and repeat this process until the withering requirements are met.

[0029] The beneficial effects of the present invention are as follows:

[0030] 1. The present invention utilizes the hot air required for withering and changes the traditional flat withering method. Instead, the tea leaves are allowed to fall freely and contact them with hot air, so that the tea leaves do not need to be turned over manually during withering, which can significantly increase the contact area between the tea leaves and the hot air, thereby increasing the withering speed of the tea leaves, allowing them to quickly dry out moisture and improving the withering efficiency of the tea leaves.

[0031] 2. The present invention further utilizes the hot air required for withering tea leaves. While providing a heat source for withering tea leaves through the flow of hot air, the flow power can also be converted into power for rotating the mounting shaft to further stir the tea leaves, causing the tea leaves to tumble automatically. At the same time, the tumbling speed is positively correlated with the hot air input speed, thereby further increasing the contact time between the tea leaves and the hot air and further improving the tea leaves withering efficiency.

[0032] 3. The present invention makes full use of the air required for withering tea leaves, converts the flow of air into a rotating power, and then converts the rotating power into a back-and-forth reciprocating power, thereby realizing the back-and-forth reciprocating motion of the bottom plate and the regular opening of the bottom end of the withering box body, that is, realizing the automatic and regular discharge of tea leaves, completing the automatic discharge, and at the same time automatically cooling the tea leaves through the lifting process of the lifting conveyor belt, and after simple collection, secondary withering can be carried out, which significantly shortens the preparation time for repeated withering and improves the withering quality.

The left and right sides of the bottom end of the withering box body 101 are connected to the fixed guide rails 5, and the side of the withering box body 101 is connected to the extension base 4. A three-way valve 104 is provided under the hot air box 102, and the front and rear ends of the three-way valve 104 are connected to the front and rear ends of the hot air box 102, and the bottom end of the three-way valve 104 is connected to the other end of the air supply hose 10, and the front and rear sides of the top of the withering box body 101 are installed with extension mounting frames 7, and the extension mounting frame 7 and the auxiliary withering assembly 8 are movably connected.

[0046] Before withering the tea leaves, the tea leaves to be withered can be put into the withering box body 101, and the auxiliary discharge component 9 can be connected to the external hot air blower, while ensuring that the input pressure meets the requirements. At the same time, an operator for transporting the tea leaves is set at the right end of the lifting conveyor belt 2 to complete the preparations before withering. At the same time, a baffle must be installed on the outer surface of the lifting conveyor belt 2 to prevent the tea leaves from falling, ensuring that the tea leaves can be lifted correctly.

[0047] like Figure 3 and Figure 6 as well as Figure 8 and Fig. 9 As shown, the auxiliary discharging assembly 9 includes a power tank 902, and a locking frame 901 is installed on the outer side of the power tank 902. The locking frame 901 is connected to one side of the withering box body 101, and the two locking frames 901 are diagonally symmetrically installed on the left and right sides of the withering box body 101. The end of the locking frame 901 away from the withering box assembly 1 is fixedly connected with an air intake valve 904, and the air intake valve 904 is connected to an external hot air blower. The end of the power tank 902 close to the withering box assembly 1 is fixedly connected with an exhaust valve 905, and the other end of the exhaust valve 905 is connected to the air supply hose 10. The middle part of the power tank 902 is movably connected with a main shaft 903, and the main shaft 903 rotates relative to the power tank 902. The outer side of the main shaft 903 is fixedly sleeved with an impeller 906 inside the power tank 902, and the top of the power tank 902 is connected to the auxiliary withering assembly 8.

[0048] When it is necessary to wither the tea leaves, the hot air can be introduced into the interior of the air inlet valve 904 by turning on the external hot air blower. At this time, the hot air can be introduced into the interior of the air supply hose 10 through the power tank 902 and the exhaust valve 905, and is transported into the interior of the three-way valve 104 through the air supply hose 10, and is distributed into the interior of the hot air box 102 through the left and right ends of the three-way valve 104, and is finally discharged through the hot air pipe 103. At this time, the tea leaves fall vertically from the top of the withering box body 101 to the bottom of the withering box body 101, and the tea leaves are fully in contact with the hot air, completing the initial withering process.

[0049] At the same time, when the hot air enters the power tank 902, it can drive the impeller 906 to rotate. At this time, the main shaft 903 rotates accordingly and transmits power to the auxiliary withering component 8.

[0050] By utilizing the hot air required for withering and changing the traditional flat withering method to allowing the tea leaves to fall freely and contact them with hot air, the tea leaves do not need to be turned over manually during withering, which can significantly increase the contact area between the tea leaves and the hot air, thereby increasing the withering speed of the tea leaves, allowing them to quickly dry out moisture and improving the withering efficiency of the tea leaves.

[0051] like Figure 1 and Figure 3 as well as Figure 6 and Figure 7 As shown, the auxiliary withering component 8 includes a mounting shaft 801 located inside the withering box body 101, a first transmission shaft 803 is fixedly mounted on the top of the mounting shaft 801, the top of the first transmission shaft 803 is movably connected to the extended mounting frame 7, the first transmission shaft 803 rotates relative to the extended mounting frame 7, a disturbance disk 802 is fixedly sleeved on the outer side surface of the mounting shaft 801 at equal distances, a synchronous belt 805 is movably sleeved on the outer side surface of the first transmission shaft 803, the other end of the synchronous belt 805 is movably sleeved on the second transmission shaft 804, the first transmission shaft 803 is transmission-connected to the second transmission shaft 804 via the synchronous belt 805, the bottom end of the second transmission shaft 804 is fixedly connected to the extension shaft 806, and the bottom end of the extension shaft 806 is connected to the top of the main shaft 903.

[0052] Embodiment: During the falling process of tea leaves, the rapid rotation of the main shaft 903 can drive the extension shaft 806 to rotate synchronously. At this time, the second transmission shaft 804 rotates accordingly, and drives the first transmission shaft 803 to rotate through the synchronous belt 805, until the installation shaft 801 is driven to rotate rapidly. At the same time, the disturbance disk 802 on the outer side of the installation shaft 801 rotates synchronously to stir the tea leaves freely falling inside the withering box body 101, so that the tea leaves tumble to a certain extent, avoiding the tea leaves from piling up and falling, thereby assisting in completing the withering process.

[0053] By further utilizing the hot air required for withering tea leaves, the flow of hot air can provide a heat source for withering tea leaves, and the flow power can be converted into the power of rotating the mounting shaft 801 to further stir the tea leaves, so that the tea leaves automatically tumble. At the same time, the tumbling speed is positively correlated with the hot air input speed, thereby further increasing the contact time between the tea leaves and the hot air, and further improving the tea withering efficiency.

[0054] like Figure 3 and Figure 6 as well as Fig. 9 As shown, the bottom end of the main shaft 903 passes through the bottom end of the power tank 902 and is fixedly connected to the first connecting rod 907. The end of the first connecting rod 907 away from the main shaft 903 is movably connected to the second connecting rod 908 through a rotating shaft. The end of the second connecting rod 908 away from the first connecting rod 907 is movably connected to a mounting seat 909 through a rotating shaft. The mounting seats 909 are respectively connected to the middle parts of the bottom ends of the two bottom plates 6. The mounting seat 909 on the right side is connected to the bottom plate 6 at the front end, and the mounting seat 909 on the left side is connected to the bottom plate 6 at the rear end.

[0055] Embodiment: As the withering proceeds and the tea leaves are put in, the tea leaves can fall automatically. At the same time, when the main shaft 903 rotates, the first connecting rod 907 rotates synchronously and drives the second connecting rod 908 to swing. At this time, the mounting seat 909 is subjected to forward pulling force and backward pushing force, and the bottom plate 6 is subjected to corresponding pulling force and pushing force. The two bottom plates 6 can be relatively close or relatively far away through two groups of symmetrically arranged auxiliary discharging components 9. When the two bottom plates 6 are relatively far away, the channel at the bottom end of the withering box body 101 can be opened to discharge the tea leaves. Through the regular reciprocating motion of the two bottom plates 6, the tea leaves can be regularly discharged and fall onto the surface of the lifting conveyor belt 2. The segmented transportation of the tea leaves can be completed as the lifting conveyor belt 2 is transported and lifted. The repeated withering process can be completed by putting the tea leaves into the withering box body 101 again until the withering quality requirements are met.

[0056] By making full use of the air required for withering tea leaves, and converting the flow of air into rotational power, the rotational power can also be converted into reciprocating power, thereby realizing the reciprocating motion of the bottom plate 6 and the regular opening of the bottom end of the withering box body 101, that is, realizing automatic and regular discharge of tea leaves, completing automatic discharge, and at the same time automatically cooling the tea leaves through the lifting process of the lifting conveyor belt 2, and after simple collection, secondary withering can be carried out, which significantly shortens the preparation time for repeated withering and improves the withering quality.

[0057] A withering method for tea withering equipment, comprising the following steps:

[0058] S1: Before use, the external hot air blower can be connected to the two auxiliary discharging components 9, and a certain hot air input pressure can be maintained, and the tea leaves to be withered are put into the withering box body 101 through the top, and the lifting conveyor belt 2 is turned on. At the same time, an operator needs to be arranged at the right end of the lifting conveyor belt 2 to transfer the tea leaves at the rightmost end of the surface of the lifting conveyor belt 2 to the withering box body 101, so as to complete the preparation before withering;

[0059] S2: At this time, the tea leaves can enter the interior of the withering box body 101 by gravity, and when the tea leaves enter, the external hot air blower can enter the interior of the power tank 902, and be discharged through the exhaust valve 905 and the air hose 10, and then discharged through the three-way valve 104 and the hot air box 102, and finally ejected through the hot air pipe 103, and the falling tea leaves can be heated and dried at this time;

[0060] S3: When the hot air enters the power tank 902, it can drive the impeller 906 to rotate. At this time, the main shaft 903 rotates accordingly, and drives the extension shaft 806 to rotate, and finally drives the disturbance plate 802 to rotate. At this time, the tea leaves entering the withering box body 101 can be stirred, and the hot air can be disturbed to increase the contact area between the hot air and the tea leaves, completing the auxiliary withering process;

[0061] S4: When the main shaft 903 rotates, it can drive the first connecting rod 907 and the second connecting rod 908 to swing, and finally drive the two bottom plates 6 to move relatively close to or away from each other. When the two bottom plates 6 move relatively away from each other, the passage at the bottom end of the withering box body 101 can be opened, and the tea leaves can be regularly discharged from the bottom end of the withering box body 101 and fall quantitatively onto the surface of the lifting conveyor belt 2.

[0062] S5: At this time, the conveyor belt 2 can be lifted to a higher place to lift the quantitatively fallen tea leaves. At this time, the operator can collect the quantitative tea leaves and put them back into the withering box body 101 for secondary withering, and repeat this process until the withering requirements are met.

[0063] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
