Description

Technical Field

[0001] The invention relates to the technical field of tea fermentation, in particular to a method for processing slightly fermented flavored white tea and a preparation device thereof. Background Art

[0002] White tea is a slightly fermented tea and a special treasure among Chinese teas. It is named because the finished tea is mostly buds, covered with white hairs, like silver and snow; slightly fermented flavored white tea is a tea drink based on slightly fermented white tea, with other flavoring substances added or special processes used to give the white tea a unique flavor and taste; when the tea leaves are fermented, they need to be stirred to improve their heat dissipation and ventilation effects.

[0003] Application No. CN202310940956.9 discloses a tea fermentation device, in which a plurality of first airflow distribution parts are arranged at intervals in the installation cavity, and the plurality of first airflow distribution parts can rotate synchronously. A first connecting pipe connected to the matching cavity is installed on one side of the mounting seat, and the first connecting pipe is suitable for introducing gas into the matching cavity. The second airflow distribution part is installed in the matching cavity and can slide along the length extension direction of the matching cavity. The distribution component is suitable for sealing the first opening and the second opening so that the first connecting pipe is connected to one of the first ventilation cavities. The distribution component is suitable for disconnecting the blockage of the first opening and the second opening so that the first connecting pipe is connected to the plurality of first ventilation cavities. A first air hole and a first matching hole matching the ventilation part are provided at the bottom of the placement frame. The present invention is conducive to uniform stirring and better wetting of the tea leaves.

[0004] However, the above technical solution cannot screen the size of tea leaves, as tea leaves of different sizes have different surface areas and internal organizational structures. Larger tea leaves have a relatively small contact area with the fermentation environment, and the fermentation speed may be slower; while smaller tea leaves have a large contact area and a faster fermentation speed. If they are not screened and treated differently, under the same fermentation conditions, large and small tea leaves are mixed together, which can easily lead to uneven fermentation, causing some tea leaves to ferment excessively and some tea leaves to ferment insufficiently, affecting the overall quality of the tea leaves, and thus making it impossible to perform corresponding fermentation treatments on tea leaves of different sizes. In addition, since the tea leaves are piled together, when the fermentation liquid is sprayed on the tea leaves, it is impossible to ensure that the tea leaves inside are also moistened by the fermentation liquid, resulting in low work efficiency.

[0015] The present invention also proposes a processing method of a micro-fermented flavored white tea processing and preparation device, and the method is as follows:

[0017] Step B: The filter plate drives the tea leaves to turn left and right while fermenting the tea leaves;

[0018] Step C: The swinging rod knocks the swinging filter plate to improve the turning effect of the tea leaves.

[0019] Preferably, when the filter plate moves to the right in step B, the friction shaft rotates clockwise, and the active clamping block drives the driven clamping block to rotate to realize the blowing work of the fan blades. When the filter plate moves to the left, the friction shaft rotates counterclockwise, and the rotating ring reciprocates back and forth in the cooperation of the driven clamping block and the return spring, so that the gas delivery piston cylinder and the liquid delivery piston cylinder spray gas and fermentation liquid to realize the fermentation treatment of the tea leaves. With the cooperation of the different slopes of the left and right sides of the friction shaft, the flipping amplitude of the left and right movement of the tea leaves is basically consistent, thereby ensuring the uniform distribution and sufficient fermentation of the tea leaves.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. The present invention improves the existing tea fermentation device. Compared with the traditional turning method, the present invention controls the filter plate to reciprocate along the trajectory of the arc groove, which not only realizes the uniform turning of the tea leaves, but also can screen the smaller tea leaves into the lower fermentation box. The turning amplitude in the lower fermentation box is small, and the sprayed fermentation liquid is sprayed in the form of mist, and the fermentation effect is relatively mild. Compared with the existing technical solutions, the present invention can screen tea leaves of different sizes and perform corresponding fermentation treatments, thereby avoiding excessive fermentation of some smaller tea leaves, thereby affecting the taste;

[0022] 2. When the filter plate moves to the right, the friction shaft rotates clockwise, and the active clamping block drives the driven clamping block to rotate to realize the blowing work of the blowing assembly, thereby improving the turning effect of the tea leaves. When the filter plate moves to the left, the friction shaft rotates counterclockwise, and the rotating ring reciprocates back and forth, so that the gas delivery piston cylinder and the liquid delivery piston cylinder spray gas and fermentation liquid to realize the fermentation treatment of the tea leaves. With the cooperation of the different slopes on the left and right sides of the friction shaft, the turning amplitude of the tea leaves moving left and right is basically consistent. When the friction shaft moves from right to left to the highest point of the arc groove, its downward gravity acceleration force will be greater, thereby further increasing the amount of tea leaves turned over when the filter plate moves to the left, so that when the tea leaves are turned left and right, the turning amplitude remains basically consistent without too much deviation, further ensuring the uniform distribution and full fermentation of the tea leaves.

[0023] 3. While the filter plate is turning over the tea leaves, the rear shaft drives the driving cam to rotate, causing the swing rod to swing back and forth along the guide shaft. When the filter plate moves to the highest point, the protruding end of the driving cam rotates to the uppermost side, and the swing rod knocks the bottom of the filter plate. The force of the swing rod knocking and the inertial force of the filter plate driving the tea leaves to move to the highest point are superimposed together to further increase the turning and screening amount of the tea leaves. While improving the turning and screening effects of the tea leaves, the mesh holes will also be unblocked, further improving the processing efficiency of the tea leaves of the present invention.

Through screening and differentiated fermentation, the characteristics of tea leaves of different sizes after fermentation can be reasonably matched according to product needs and goals to achieve an ideal combination of taste and aroma.

[0036] like Figure 1-Figure 10 As shown, the present invention provides a technical solution: a micro-fermented flavored white tea processing and preparation device, comprising a workbench 1, two groups of fermentation boxes 2 are placed on the upper end surface of the workbench 1, four groups of vertical grooves 12 are fixedly opened on the surface of the fermentation box 2, four groups of clamps 10 are fixedly connected to the upper end surface of the workbench 1, two groups of arc grooves 11 are fixedly connected on the surface of the clamps 10, a friction shaft 16 is slidably connected inside the left arc groove 11, and the friction shaft 16 is slidably connected to the inside of the vertical groove 12, a filter plate 13 is arranged inside the fermentation box 2, and support plates 14 are fixedly connected to the left and right sides of the lower end surface of the filter plate 13, and the friction shaft 16 is rotatably connected to the middle part of the front support plate 14;

[0037] An installation box 15 is fixedly installed on the left side of the lower end surface of the filter plate 13, and a blowing assembly is arranged inside the installation box 15.

[0038] Furthermore, if Figure 2 As shown, the slope of the upper arc groove 11 is greater than that of the lower arc groove 11, and the slope of the left part of the arc groove 11 is greater than that of the right part. A fixed platform 5 is fixedly installed on the left side of the upper end surface of the workbench 1, and two groups of driving cylinders 6 are fixedly installed on the surface of the fixed platform 5.

The output end movement frequency of the upper and lower driving cylinders 6 works alternately. When the upper fermentation box 2 moves to the right for blowing, the lower fermentation box 2 is performing fermentation spraying. By staggering the work, the tea leaves filtered by the upper filter plate 13 can continue to be fermented after the upper treatment. When the tea leaves screened by blowing and turning fall into the lower fermentation box 2, the fermentation liquid spraying and wetting work can be followed. When the tea leaves screened after being sprayed and moistened with the fermentation liquid fall into the lower fermentation box 2, the blowing and turning work can be followed, thereby further improving the screening effect of the present invention.

[0039] Furthermore, in order to further control the fermentation efficiency of small tea leaves, the telescopic speed of the output end of the lower driving cylinder 6 is smaller than the telescopic speed of the output end of the upper driving cylinder 6, so as to avoid excessive fermentation of the tea leaves affecting the taste.

[0040] Furthermore, the rear end face of the driven clamping block 162 is rotatably connected to a rotating ring 163, and a connecting plate 164 is fixedly connected to the left side of the surface of the rotating ring 163.

Both the input and output ends of the air piston cylinder 85 and the liquid infusion piston cylinder 86 are provided with one-way valves. Two groups of cavities are provided inside the upper output box 81, and one group of cavities is provided inside the lower output box 81. The opening size of the lower nozzle 82 is smaller than the opening size of the upper nozzle 82.

[0042] Furthermore, the surface of the left rear support plate 14 is rotatably connected to a rear shaft 18, which is slidably connected to the inside of the rear arc groove 11, the front end face of the rear shaft 18 is fixedly connected to a driving cam 19, the rear end face of the mounting box 15 is fixedly connected to a fixing block 22, the surface of the fixing block 22 is fixedly connected to a guide shaft 21, the surface of the guide shaft 21 is connected to a rocker arm 20, a protrusion is provided at the right end of the rocker arm 20, the rocker arm 20 is located on the upper side of the surface of the driving cam 19, and the right end of the rocker arm 20 is located below the filter plate 13.

[0043] Furthermore, the blowing assembly includes fan blades 158, and the internal rotation of the installation box 15 is connected to the active bevel gear 151, the front end face of the active bevel gear 151 is fixedly connected to the rear end face of the driven clamping block 162, the surface of the active bevel gear 151 is meshingly connected to the driven bevel gear 152, and the right end face of the driven bevel gear 152 is fixedly connected to the active bevel wheel 153, the internal rotation of the installation box 15 is connected to the inclined transmission shaft 154, the surface of the transmission shaft 154 is slidably connected to the friction wheel 155, the lower side of the interior of the installation box 15 is rotatably connected to the matching rod 157, the left end face of the matching rod 157 is fixedly connected to the driven bevel wheel 156, the friction wheel 155 is slidably connected between the active bevel wheel 153 and the driven bevel wheel 156, the upper end of the transmission shaft 154 is fixedly connected to the fan blades 158, and the surface of the installation box 15 is provided with a dustproof net.

[0044] Furthermore, in order to further improve the stability of the filter plate 13 when it reciprocates left and right, a matching shaft 17 is rotatably connected between the front and rear support plates 14 at the right end, and the front and rear sides of the matching shaft 17 are slidably connected to the inside of the arc groove 11 at the right end, and the front and rear sides of the upper fermentation box 2 are fixedly connected with a slider 23, and the front and rear sides of the upper end face of the workbench 1 are fixedly connected to the limiting frame 9, and the slider 23 is slidably connected to the inside of the limiting frame 9.

[0045] Furthermore, if Figure 2As shown, the upper end of the upper fermentation box 2 is detachably connected with a box cover 3, and the lower end of the workbench 1 is provided with a tea residue collection box 4 for collecting tea residues.

[0046] A processing method of a slightly fermented flavored white tea processing and preparation device, the method comprising the following steps:

[0047] Step A: putting tea leaves to be filtered into the fermentation box 2, which turns the tea leaves over and sieves them according to their size, and evenly distributes the tea leaves in the fermentation box 2;

[0048] Step B: The filter plate 13 drives the tea leaves to turn left and right while fermenting the tea leaves;

[0049] Step C: The swing rod 20 knocks the swinging filter plate 13 to improve the turning effect of the tea leaves.

[0050] Furthermore, when the filter plate 13 moves to the right in step B, the friction shaft 16 rotates clockwise, and the active clamping block 161 drives the driven clamping block 162 to rotate to realize the blowing work of the fan blade 158. When the filter plate 13 moves to the left, the friction shaft 16 rotates counterclockwise, and the rotating ring 163 reciprocates back and forth under the cooperation of the driven clamping block 162 and the return spring 166, so that the gas delivery piston cylinder 85 and the infusion piston cylinder 86 spray gas and fermentation liquid to realize the fermentation treatment of the tea leaves. With the cooperation of the different slopes of the left and right sides of the friction shaft 16, the flipping amplitude of the tea leaves moving left and right is basically consistent. When the friction shaft 16 moves from right to left to the highest point of the arc groove 11, its downward gravity acceleration force will be greater, thereby further increasing the amount of tea leaves flipped when the filter plate 13 moves to the left, so that when the tea leaves are flipped left and right, their flipping amplitude remains basically consistent and will not produce too much deviation, thereby ensuring the uniform distribution and full fermentation of the tea leaves.

[0051] Working principle: After installing the preparation device, put the tea leaves to be fermented into the fermentation box 2, and the tea leaves fall on the filter plate 13. The output end of the driving cylinder 6 drives the driving shaft 7 fixedly connected thereto to move, and the driving shaft 7 pushes the fermentation box 2 to reciprocate left and right. Since the outer ends of the friction rotating shaft 16 and the matching shaft 17 are slidably connected to the inside of the arc groove 11, and the middle part thereof is slidably connected to the inside of the vertical groove 12, under the limitation of the vertical groove 12, the filter plate 13 inside the fermentation box 2 will perform synchronous reciprocating motion in the arc trajectory of the arc groove 11, thereby realizing the turning of the tea leaves on the upper side driven by the vertical groove 12, and the size screening of the tea leaves can be achieved while the tea leaves can be flattened, so that the tea leaves can be evenly distributed inside the fermentation box 2 to achieve full fermentation;

[0052] The sieved tea leaves fall on the upper side of the filter plate 13 in the lower fermentation box 2 for flipping and sieving, and the smaller and unusable tea residues are sieved into the tea residue collection box 4. Since the slope of the upper arc groove 11 is greater than that of the lower arc groove 11, the upper fermentation box 2 can hold more tea leaves with larger size, and the filter plate 13 will perform flipping with a larger movement amplitude;

[0053] When the filter plate 13 moves to the right, the friction shaft 16 rotates clockwise, and the rear end face of the friction shaft 16 drives the active clamping block 161 fixedly connected thereto to rotate, and the active clamping block 161 drives the driven clamping block 162 fixedly connected thereto to rotate synchronously, and the driven clamping block 162 drives the spline shaft 165 splined thereto to rotate, and the spline shaft 165 drives the active bevel gear 151 fixedly connected thereto to rotate, and the active bevel gear 151 drives the driven bevel gear 152 meshing therewith to rotate, and the driven bevel gear 152 drives the active bevel wheel 153 fixedly connected thereto to rotate, and in coordination with the driven bevel wheel 156, the driven bevel gear 152 drives the active bevel wheel 153 fixedly connected thereto to rotate. The friction wheel 155 connected by sliding friction rotates, and the friction wheel 155 drives the transmission shaft 154 fixedly connected thereto to rotate, and the transmission shaft 154 drives the fan blades 158 fixedly connected thereto to rotate. When the fan blades 158 rotate, air is blown to the tea leaves flipped to the right, thereby further improving the turning efficiency of the tea leaves. When the friction shaft 16 moves to the uppermost side of the arc groove 11 and starts to move downward, the friction shaft 16 further increases the rotation speed under the gravity acceleration of the filter plate 13, and at this time, the tea leaves flipped by the filter plate 13 have been flipped to the highest point in the air, and the fan blades 158 further increase the blowing force, thereby further increasing the turning effect of the tea leaves, thereby achieving uniform distribution of the tea leaves.

[0054] When the rear shaft 18 moves to the rightmost side of the arc groove 11 and starts to move to the left to reset, the friction shaft 16 rotates counterclockwise at this time, and the friction shaft 16 drives the active clamping block 161 fixedly connected thereto to rotate, and the arc surface part of the driven clamping block 162 is squeezed and moved backward by the active clamping block 161, and the return spring 166 is squeezed and compressed by the driven clamping block 162. When the active clamping block 161 no longer squeezes the driven clamping block 162, the driven clamping block 162 moves forward to reset under the elastic reset of the return spring 166, thereby realizing the forward and backward movement of the driven clamping block 162. Reciprocating motion, the driven clamping block 162 drives the rotating ring 163 connected to it to reciprocate back and forth, the rotating ring 163 drives the connecting plate 164 fixed to it to reciprocate back and forth, the connecting plate 164 drives the infusion piston rod 87 and the gas transmission piston rod 88 fixed to it to perform reciprocating piston motion back and forth, the infusion piston rod 87 controls the infusion piston cylinder 86 to perform piston liquid spraying, and the gas transmission piston rod 88 controls the gas transmission piston cylinder 85 to perform piston jetting. Since two groups of cavities are provided inside the output box 81, the output box 81 will alternately spray gas and fermentation liquid;

[0055] Since the blowing assembly will perform blowing work when the filter plate 13 moves to the right, when the tea leaves on the filter plate 13 are flipped left and right, the amount of tea leaves flipped to the right is greater than the amount of tea leaves flipped to the left, but the distance between the leftmost side and the uppermost side of the arc groove 11 is greater than the distance between the rightmost side and the uppermost side, so when the friction shaft 16 moves from right to left to the highest point of the arc groove 11, its downward gravity acceleration force will be greater, thereby further increasing the amount of tea leaves flipped when the filter plate 13 moves to the left, so that when the tea leaves are flipped left and right, the flipping amplitude is basically consistent and will not produce too much deviation, and when the filter plate 13 moves to the left, the output box 81 will also alternately spray gas and fermentation liquid, and then the tea leaves are repeatedly flipped, thereby ensuring that the tea leaves are evenly distributed and can be evenly fermented;

[0056] like Figure 1 As shown, since the slope of the upper arc groove 11 is greater than that of the lower arc groove 11, the tea leaves on the lower filter plate 13 are flipped left and right, and the blowing force of the blowing component is smaller than that of the upper side, so as to avoid that the tea leaves with a smaller area and a smaller number are subjected to the same fermentation treatment as the tea leaves on the upper side, resulting in excessive fermentation force and affecting the fermentation effect. In addition, since there is only one set of cavities inside the lower output box 81, the fermentation liquid and gas output by the lower gas delivery piston cylinder 85 and the liquid delivery piston cylinder 86 are mixed together, and then sprayed out through the nozzle 82 with a smaller opening. At this time, the fermentation liquid sprayed out of the output box 81 is in a mist state, which can further perform an appropriate amount of fermentation treatment on a smaller number of smaller tea leaves.

[0057] While the filter plate 13 is flipping left and right, the rear shaft 18 also rotates in coordination with the rear clamping plate 10 and the arc groove 11, and the rear shaft 18 drives the driving cam 19 fixedly connected thereto to rotate. Since the swing rod 20 slides on the surface of the swing rod 20, when the protruding part of the driving cam 19 rotates to the upper side, the swing rod 20 will rotate upward along the guide shaft 21 and knock the filter plate 13 through the protruding end. When the swing rod 20 knocks the filter plate 13, the filter plate 13 just moves to the highest point, and the arc groove 11 knocks at this time. The knocking force and the inertial force of flipping to the highest point are superimposed together, which can further improve the flipping effect of the tea leaves on the surface of the filter plate 13, and can also prevent some tea leaves from accumulating in the mesh and causing blockage.

[0058] While embodiments of the present invention have been shown and described, those skilled in the art will appreciate that numerous changes, modifications, substitutions and variations may be made to the embodiments without departing from the spirit and scope of the present invention, the scope of which is defined by the claims and their equivalents.
