[0002] Phoenix Dancong is known as the "perfume of tea" and is famous for its many scents and unique flavor. During the shaking process, the tea cell tissue increases its cell absorption capacity due to shaking, so that the water in the tea stems is transported to the veins and leaves and evaporated, and at the same time, the aromatic substances and soluble substances are transported to the leaves. The drum shaking machine is a kind of equipment used for tea processing. It is mainly used in the shaking process, that is, in the tea processing process, the tea leaves are rubbed against the drum wall and between the tea leaves through the rotation of the drum to improve the quality of the tea.

[0003] At present, a spiral stirring blade is generally provided on the inner wall of the drum, which tends to make the tea leaves move closer to one end of the drum; and the stirring blade is generally fixed and cannot be adjusted according to the amount of tea leaves and the size of leaves, resulting in unsatisfactory stirring of the tea leaves. Summary of the invention

[0004] In a first aspect, the present application provides a device for making tea leaves green.

[0005] This application adopts the following technical solutions:

[0007] By adopting the above technical solution, when the drum bone resistance member drives one of the sliding blocks to slide, the elastic member can synchronously drive the remaining sliding blocks to slide under the action of the elastic member, so that the elastic member is compressed, and the elastic strip is bent and extended in the inner cavity of the drum, so that the elastic strip can better roll the tea leaves when the drum rotates. If there are fewer or smaller tea leaves, less stirring force is required, the resistance member is released from the sliding block, and the elastic member drives the sliding block to reset, so that the elastic strip is gradually retracted in the direction of approaching the extension strip.

[0008] Optionally, the resistance member includes a resistance plate arranged at one end of the inner cavity of the drum, and a resistance strip arranged on the resistance plate, the resistance strip and the extension strip correspond one-to-one and are slidably inserted in the extension strip, and the outer end surface of the drum is provided with a first element for driving the resistance plate to slide.

[0020] In a second aspect, the present application provides a manual fermentation process for removing green leaves and restoring freshness.

[0021] A manual fermentation process for removing green tea and returning it to its original state, using the above-mentioned green tea making device, comprises the following steps:

[0022] (1) After the tea leaves are picked, they are withered by exposure to sunlight; the withered tea leaves are then moved to a drying rack indoors and placed in a cool, ventilated place to allow the leaves to release heat, lower the leaf temperature, and balance the moisture in the leaves, so as to prepare for the tea leaves to drain;

[0023] (2) Making green tea: The tea leaves prepared in the above step are rotated 360 degrees in a massage-like manner, so that the leaves collide with each other and lose water and ferment. The collision process is intermittently performed 3 times until the leaves have red edges. The leaves are then placed on a bamboo sieve and the sieve is shaken. The leaves are then placed in a green tea shaking machine and rotated rapidly to increase the water flow rate, so that the green smell of the tea leaves is removed and the tea leaves are fully fermented to form more internal substances.

[0024] (3) The leaves obtained above are blanched at 200-230°C and then charcoal roasted.

DETAILED DESCRIPTION

[0032] The following is combined with Figure 1-3 This application is described in further detail.

[0033] Example 1

[0034] The present application embodiment discloses a tea-leaf-making device, which is used for shaking tea leaves. Figure 1 The tea-making device comprises a frame 1, a drum 2 rotatably mounted on the frame 1, and a driving source 3 for driving the drum 2 to rotate. The drum 2 is a cylindrical structure, and the driving source 3 is selected from a belt drive. An opening is opened at one end of the drum 2 away from the driving source 3, and an opening plate 16 for covering the opening is installed on the drum 2. The opening plate 16 is positioned by means of clamping, bolts, etc., and tea leaves are loaded and unloaded through the opening.

[0035] Reference Figure 1 and Figure 2 The inner wall of the drum 2 is fixedly mounted with an extension bar 4, which is in the shape of a long strip and extends in a direction parallel to the axis of the drum 2. A plurality of extension bars 4 are evenly arranged along the circumference of the drum 2. When the drum 2 rotates, the extension bars 4 can roll the tea leaves, thereby promoting the friction effect of the tea leaves, destroying the tea cell tissue, activating the polyphenol oxidase of the tea leaves, causing enzymatic oxidation and condensation of the cell phenolic substances, producing brown quinone substances, causing the tea leaves to turn brown, and the leaves to turn red.

[0036] In further, combined Figure 3 , the extension bar 4 is an internal hollow structure, and the surface of the extension bar 4 is provided with a clearance groove 15 connected to the inner cavity of the extension bar 4. A plurality of sliding blocks 5 are slidably installed in the extension bar 4, and an elastic member 6 is connected between two adjacent sliding blocks 5, and the elastic member 6 is preferably a spring. An elastic strip 7 is also connected between two adjacent sliding blocks 5, and the elastic strip 7 is connected to one end of the sliding block 5 close to the clearance groove 15, and the elastic strip 7 is preferably a rubber strip with a certain elasticity. When the two sliding blocks 5 are close to each other, the spring is compressed, and the elastic strip 7 can be bent and extended into the inner cavity of the drum 2, so that the elastic strip 7 can increase the stirring effect on the tea leaves. A resistance member 8 is installed on the drum 2, and the resistance member 8 can be used to drive the sliding block 5 to slide to adjust the elastic strip 7. Further, elastic sheets 14 are arranged at intervals on the extension bar 4, and the elastic sheets 14 can cover the clearance groove 15.

[0037] Reference Figure 2 and Figure 3 The abutment member 8 includes an abutment plate 81 located in the drum 2, and an abutment strip 82 installed on the abutment plate 81. The abutment plate 81 is located at one end of the drum 2 close to the driving source 3. The abutment strip 82 corresponds to the extension strip 4 one by one, and the abutment strip 82 is slidably inserted in the extension strip 4 and abuts against the sliding block 5. A first element 83 is installed on the outer wall of the drum 2. The first element 83 can be a cylinder. Two cylinders are provided, and their piston rods are connected to the abutment plate 81. The abutment plate 81 can be driven to move in the drum 2 by the first element 83, thereby pushing the sliding block 5 to slide. In other embodiments, the first element 83 can also be selected from a device such as an electric telescopic cylinder that can realize the linear motion of the abutment plate 81.

[0038] Reference Figure 2 and Figure 3 A push plate is slidably installed in the drum 2, and the movement direction of the push plate is parallel to the axial direction of the drum 2. A second element 17 for driving the push plate to move is also installed on the drum 2. The second element 17 includes a screw 171 rotatably connected to the drum 2, and two screws 171 are provided, and the screw 171 and the push plate are threadedly connected. In order to make the screw 171 rotate more stably, a bearing seat can be provided on the inner wall of the drum 2. A motor connected to the screw 171 is installed on the end surface of the drum 2, so that the rotation of the screw 171 can drive the push plate to move. The push plate is a circular plate structure, and a notch is provided at the position of the push plate corresponding to the extension strip 4. When unloading, the push plate moves in the direction of the opening of the drum 2, which is helpful for the unloading of tea leaves.

[0039] During operation, the push plate is located at one end of the drum 2 close to the driving source 3, and an isolation space 9 is formed between the push plate and the end surface of the drum 2, and the contact plate 81 is located in the isolation space 9, so that the push plate does not affect the movement of the contact plate 81. A plurality of air holes 11 are provided on the side wall of the drum 2 corresponding to the isolation space 9, and an air source connector 10 is installed on the outer wall of the drum 2, and the air source connector 10 is a connecting ring 13 rotatably connected to the outer wall of the drum 2. An annular groove 12 is provided on the inner wall of the connecting ring 13, and the annular groove 12 corresponds to the air hole 11. The connecting ring 13 is used to pass through a pipeline and an external air source, such as a blower, an exhaust fan, etc. The push plate is a porous structure. When unloading, the drum 2 rotates, and the air source supplies air to the annular groove 12 through the connecting ring 13. The gas enters the isolation space 9 and then blows through the push plate, which is conducive to the movement of tea leaves to the opening of the drum 2.

[0040] The implementation principle of the tea-leaf-making device of the embodiment of the present application is as follows: the drum 2 rotates to make the tea-leaf green, and it is determined whether the elastic strip 7 needs to be bent out to increase the disturbance of the tea-leaf according to the condition of the tea-leaf. When feeding, the push plate moves toward the end of the drum 2, and at the same time, it is connected to the air source through the connecting ring 13, so that the airflow can push the tea-leaf toward the opening of the drum 2.
