Description

Technical Field

[0001] The present application relates to the technical field of tea processing equipment, and in particular to a black tea withering trough capable of withering evenly. Background Art

[0002] Withering is the first process in the initial processing of Gongfu black tea. Its principle is to change the enzyme activity of fresh tea leaf cells through the action of wind and temperature, so that the substances contained in the tea leaf undergo slow and balanced chemical changes. At the same time, the water loss rate of the fresh tea leaf reaches 35%-40%, and the leaf color changes from bright green to dark green, loses its luster, and becomes soft and sticky. The perfection of the withering process will lay the foundation for the normal progress of other processes and the formation of the color, aroma and taste of black tea. In other words, if the withering process of Gongfu black tea is missing, the excellent quality of Gongfu black tea will be out of the question. Therefore, it can be seen that withering is an important process in the preparation of Gongfu black tea.

[0003] In the related art, a Chinese patent with publication number CN213719748U proposes a black tea withering tank, including a tank body and a fan, a wind collecting pipe is fixed at the bottom of the inner cavity of the tank body, and one end of the wind collecting pipe is connected to the fan, a branch pipe is evenly connected to the wind collecting pipe along the length direction, and a guide tube is connected to the top of the branch pipe, an electric heating rod is fixed between the inner walls of both sides of the tank body, a rotating shaft 1 is rotatably installed on the inner walls of both sides of the tank body, a plurality of tea boxes are fixed between the two rotating shafts 1, a motor is installed on one side wall of the tank body, and the output shaft of the motor passes through the side wall of the tank body and is connected to the rotating shaft 1, a box cover is hinged on the top of the tea box, and ventilation holes are arranged in arrays on the bottom wall and the box cover of the tea box. The utility model can make the tea leaves evenly exposed to wind and form a stable withering environment.

[0004] The above-mentioned related technologies have the following defects: in the above scheme, the tea leaves are placed in a closed tea box, and the tea leaves are withered by rotating the tea box, which results in a large volume of the required withering trough, which is not conducive to the utilization of workshop space in large-scale industrial production, and the tea leaves in the tea box are easily stacked in one place during the turning process, which may cause different withering degrees and qualities of the same batch of tea.

[0031] The technical solution of the present application will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present application.

[0032] The present application embodiment discloses a black tea withering tank that can wither evenly. Figure 1 A black tea withering tank capable of withering evenly comprises:

[0033] The tank body 1 is in the shape of an elongated strip and is provided with a cover 11 thereon.

[0034] The screen 2 is fixedly connected to the inside of the tank body 1 and is arranged horizontally. The screen 2 is specifically made of a stainless steel mesh, which can reduce the impact on the taste of tea.

[0035] The lighting system is arranged on the bottom wall of the cover 11, and is used to supplement light to the tea leaves on the screen 2, simulating sunlight withering, which can promote the photosynthesis of the tea leaves, enhance the aroma and freshness of the tea leaves, avoid the phenomenon of "dead green" of the product during withering, and thus improve the quality of the tea leaves.

[0036] The air equalizing plate 3 is sealed and fixed to the inner wall of the tank body 1, and is located below the screen 2. The air equalizing plate 3 and the bottom wall of the tank body 1 enclose an air equalizing cavity 31. The air equalizing plate 3 is penetrated by a plurality of air equalizing holes 32 arranged in a matrix. The spacing between two adjacent air equalizing holes 32 is equal. The air equalizing holes 32 are expanded from bottom to top to increase the volume of rising hot air and the blowing range.

[0037] The hot air system is used to input hot air into the air equalization chamber 31. It is set by conventional means and will not be described in detail here.

[0038] After such arrangement, when withering the tea leaves, the tea leaves to be treated are spread on the screen 2, the cover 11 is closed, and then the lighting system and the hot air system are started. The hot air system continuously inputs hot air into the air distribution chamber 31, and outputs it upward from the multiple air distribution holes 32 on the air distribution plate 3, so that the hot air can be blown more evenly to the tea leaves spread on the screen 2, which can effectively ensure the uniformity of tea withering; and because the hot air is from bottom to top, the tea leaves stacked and spread on the screen 2 can be blown more fully with hot air, which can significantly increase the amount of tea leaves withered at one time and improve the processing capacity. The lighting system supplements the light for the tea leaves on the screen 2, which can improve the quality of the tea leaves after withering. At the same time, the internal space of the tank body 1 is compactly arranged, which can reduce the floor space of the tank body 1 and facilitate the layout of the workshop.

[0039] At the same time, in order to further improve the efficiency of black tea withering, the air intake of the hot air system can be appropriately increased, but in order to avoid the tea leaves on the screen 2 being stacked after being blown by the hot air, affecting the consistency of the withering quality of the same batch of tea leaves. Figure 1 A plurality of vertically arranged partitions 21 are fixedly connected to the screen 2, and the plurality of partitions 21 are arranged at intervals along the length direction of the trough body 1, and the plurality of partitions 21 separate the plurality of withering zones 22 above the screen 2; baffles 23 are fixedly connected to both sides of the partition 21 extending into two adjacent withering zones 22, and the baffles 23 are arranged along the width direction of the trough body 1, specifically, the baffles 23 are arranged on the partitions 21 at an upward inclination, and the baffles 23 are made of transparent material to reduce the influence on the lighting system.

[0040] In this way, after the tea leaves to be processed are dispersed in multiple withering zones 22 by the partition 21, the baffle 23 is used to block the loaded tea leaves to a certain extent, which can effectively avoid the excessive concentration and stacking of tea leaves; at the same time, tea leaves of different qualities can also be placed in different withering zones 22 to improve the utilization rate of the withering trough of the present application.

[0041] Further, see Figure 1 A plurality of wind shielding plates 4 corresponding to the plurality of withering zones 22 are slidably disposed on the upper end surface of the wind balancing plate 3, and a plurality of ventilation holes 41 having openings not smaller than the wind balancing holes 32 and arranged in a matrix are formed through the wind shielding plate 4, and the spacing between two adjacent wind balancing holes 32 along the length direction of the trough body 1 is greater than the aperture of the ventilation hole 41;

[0042] When the wind shield 4 moves to the point where the ventilation hole 41 thereon is located between two adjacent wind equalizing holes 32, the wind shield 4 blocks the plurality of wind equalizing holes 32 in the corresponding area. Figure 1 The wind shield 4 on the left side of the center.

[0043] In this way, the multiple wind shields 4 can be moved independently so that the wind balancing plates 3 can block the multiple wind balancing holes 32 corresponding to the corresponding withering zones 22 or reduce the excess air volume to achieve different processing requirements; for example, when the amount of tea to be processed is small, the multiple wind balancing holes 32 corresponding to the withering zones 22 where no tea leaves are put can be blocked to improve the utilization rate of hot air in the hot air system and reduce energy consumption. For example, when the thickness of tea leaves put into a single withering zone 22 is small, the wind shield 4 can also be moved to reduce the actual air volume of the multiple wind balancing holes 32 corresponding to the withering zone 22, thereby controlling the withering uniformity of the same batch of tea leaves.

[0044] In order to facilitate the adjustment of the wind shield 4 outside the tank body 1, refer to Figure 1 and Figure 2 A plurality of long grooves 12 corresponding to the plurality of wind shields 4 are penetrated and opened on the side wall of the trough body 1. The long grooves 12 are arranged along the length direction of the trough body 1. A lever 51 with one end extending outside the trough body 1 is slidably arranged in the long groove 12. A sealing plate 52 with a length not less than twice the length of the long groove 12 is slidably arranged inside the trough body 1. The sealing plate 52 is fixedly connected to the wind shield 4. One end of the lever 51 close to the middle of the trough body 1 is fixedly connected to the middle of the sealing plate 52.

[0045] In this way, by moving the lever 51 outside the slot body 1, the wind shielding plate 4 can be driven to move on the wind equalizing plate 3, and when the lever 51 moves in the long slot 12, the sealing plate 52 can always close the long slot 12 to prevent hot air from leaking out.

[0046] In addition, refer to Figure 1 The above-mentioned lighting system includes a plant fill light 61 installed on the cover 11, and a plurality of plant fill lights 61 are arranged at intervals along the length direction of the long groove 12, and a reflective layer 62 is attached to the bottom wall of the cover 11; thereby, the tea leaves on the screen 2 can be supplemented with light more evenly with the aid of the plurality of plant fill lights 61, thereby ensuring the withering quality of the tea leaves.

[0047] The implementation principle of a black tea withering tank capable of withering evenly in the present application embodiment is as follows:

[0048] When withering tea leaves, the tea leaves to be treated are spread on the screen 2, the cover 11 is closed, and then the lighting system and the hot air system are started. The hot air system continuously inputs hot air into the air distribution chamber 31, and outputs it upward from the multiple air distribution holes 32 on the air distribution plate 3, so that the hot air can be blown more evenly to the tea leaves spread on the screen 2, which can effectively ensure the uniformity of tea withering; and because the hot air is from bottom to top, the tea leaves stacked and spread on the screen 2 can be blown more fully with hot air, which can significantly increase the amount of tea leaves withered at one time and improve the processing capacity. At the same time, the internal space of the tank body 1 is compactly arranged, which can reduce the space occupied by the tank body 1 and facilitate the layout of the workshop.
