[0001] The present invention relates to the technical field of tea fermentation, in particular to a selenium-enriched tea fermentation method and an automatic temperature-controlled tea fermentation machine. Background Art

[0002] During the production process, selenium-rich tea needs to go through a fermentation step. During the fermentation process, workers need to turn the tea leaves from time to time to allow the tea leaves to better contact with oxygen, thereby achieving a better fermentation effect.

[0003] Before workers turn the tea leaves, they need to gather the tea leaves on the tray and then turn them over. When gathering the tea leaves, some of the tea leaves will stick to the tray because they are moist and sticky after fermentation, making it difficult for workers to turn the tea leaves over. At the same time, if workers forcibly pull off the stuck tea leaves, the tea leaves will break, thus affecting the quality of the tea. Summary of the Invention

[0004] In order to overcome the shortcomings that when workers gather tea leaves, some tea leaves adhere to the receiving tray, making it difficult for workers to turn the tea leaves over, and at the same time, workers forcibly pull off the adhered tea leaves, causing the tea leaves to break, thereby affecting the quality of the tea leaves, the present invention provides a selenium-enriched tea fermentation method and an automatic temperature-controlled tea fermentation machine.

The implementation conditions not specified are generally those used in routine experiments.

[0030] Example 1

[0031] A selenium-enriched tea fermentation method and a tea fermentation machine with automatic temperature control, such as Figures 1-6 As shown, it includes a fermentation cabinet 1; an automatic temperature control module is provided on the fermentation cabinet 1;

[0032] It also includes a suspension rod 101, a receiving cloth 102, a moving block 103, a connecting rod 104, a mounting block 105 and a spreading rod 106; two suspension rods 101 are fixedly connected in the fermentation cabinet 1; three receiving cloths 102 are installed on each suspension rod 101, and the receiving cloth 102 is set as elastic cloth; four connecting plates 10201 are fixed on each receiving cloth 102; the lower side of each receiving cloth 102 is connected to the moving block 103; each suspension rod 101 is provided with six rails 10102; each moving block 103 is provided with two first electric sliders 10301, and each first electric slider 10301 is located on the corresponding rail 1 0102; each moving block 103 is connected to four connecting rods 104 through a rotating rod; each suspension rod 101 is fixed with the same number of connecting rods 104 as the receiving cloth 102; each suspension rod 101 is fixed with three mounting blocks 105; each mounting block 105 is connected to four spreading rods 106 through a rotating rod, and all spreading rods 106 are connected to the corresponding connecting plate 10201 through a rotating rod; each spreading rod 106 is provided with two sliding grooves 10601; a sliding rod 10401 is provided at the lower part of each connecting rod 104, and each sliding rod 10401 is located between the corresponding two sliding grooves 10601.

[0033] It also includes a rotating block 201 and a lever 202; a rotating block 201 is arranged above each moving block 103, and the upper side of the rotating block 201 is connected to the receiving cloth 102; a rotating ring 10101 is installed on the rotating block 201; the rotating parts on each rotating block 201 are connected to four levers 202 through electric rotating rods.

[0034] In order to reduce the friction between the lever 202 and the receiving plate, the side of the lever 202 in contact with the receiving plate is set as an arc surface.

[0035] In order to better stir the tea leaves adhered to the receiving plate, several bumps are arranged on the side of the lever 202 in contact with the receiving plate.

[0036] In order to prevent the lever 202 from damaging the receiving plate when the lever 202 scrapes the receiving plate, the lever 202 is made of rubber material.

[0037] It also includes a second electric slider 301 and a protective frame 302; two symmetrically arranged slide rails 1001 are arranged on the fermentation cabinet 1; a second electric slider 301 is arranged on each slide rail 1001; a protective frame 302 is installed on each second electric slider 301, and the protective frame 302 is made of rubber material.

[0038] In order to better intercept the flying tea powder, all the protective frames 302 are set in a shape that is wider at the top and narrower at the bottom.

[0039] During the production process of selenium-rich tea, it needs to go through a fermentation step. During the fermentation process of tea, workers need to turn the tea leaves irregularly to make the tea leaves better contact with oxygen, so as to achieve a better fermentation effect. Before the workers turn the tea leaves, they need to gather the tea leaves on the receiving plate and then turn them. When gathering the tea leaves on the receiving plate, because the tea leaves are in a wet state and have a certain viscosity after fermentation, some tea leaves will adhere to the receiving plate, making it difficult for workers to remove them. At the same time, if workers forcefully remove the tea leaves adhered to the receiving plate, the tea leaves will break, thus affecting the quality of the tea.

[0040] When the tea leaves in the fermentation cabinet 1 need to be turned over by a worker, the first electric slider 10301 on the moving block 103 drives the moving block 103 and the parts connected thereto to move downward along the track 10102 on the suspension rod 101, thereby pushing the corresponding spreading rod 106 through the connecting rod 104 on the moving block 103, causing the spreading rod 106 to rotate around the rotating rod on the spreading rod 106, and then pushing the corresponding connecting plate 10201 on the receiving cloth 102 to move around through the spreading rod 106, thereby stretching the edge of the receiving cloth 102 around, and the middle part of the receiving cloth 102 will be pushed through the moving block 103 and The connected parts are stretched downward, and the first electric slider 10301 stops moving when it moves to the lowest end of the track 10102, thereby making the receiving cloth 102 appear low in the middle and high around. It should be noted that: while the opening rod 106 pushes the corresponding connecting plate 10201 on the receiving cloth 102 to move around, it will also move downward under the drive of the opening rod 106, and the downward movement height of the connecting plate 10201 on the receiving cloth 102 is less than the height of the middle part of the receiving cloth 102 driven by the moving block 103; thereby, the tea leaves are moved toward the center of the receiving cloth 102, thereby completing the gathering of the tea leaves. During the stretching process of the receiving cloth 102, the receiving cloth 102 will become tighter and tighter, thereby loosening the tea leaves adhered to the receiving cloth 102, and then causing the tea leaves adhered to the receiving cloth 102 to gather toward the center of the receiving cloth 102, thereby improving the practicality of the present invention. After the tea leaves are turned over, the moving block 103 is reset to restore the receiving cloth 102 to a horizontal state, and then the workers evenly spread the turned tea leaves on the receiving cloth 102 to continue fermentation.

[0041] During the stretching of the receiving cloth 102, the DD motor 20101 on the rotating block 201 also drives the lever 202 to rotate, thereby shaking the receiving cloth 102, accelerating the loosening of tea leaves adhered to the receiving cloth 102, and simultaneously accelerating the gathering of tea leaves toward the center of the receiving cloth 102. In order to adapt the lever 202 to the deformation of the receiving cloth 102 and improve the use effect of the lever 202, during the rotation of the lever 202 by the rotating block 201, the electric rotating shaft 20102 on the rotating block 201 drives the lever 202 to flip upward or downward, so that the lever 202 is always in contact with the receiving cloth 102, thereby enabling the lever 202 to adapt to the deformation of the receiving cloth 102, further improving the practicality of the present invention.

[0042] When workers stir the tea leaves, tea dust can fly, contaminating the interior of the fermentation chamber 1 and increasing the number of times workers need to clean the chamber 1, further increasing their workload. Therefore, before workers stir the tea leaves, they use the second electric slider 301 to move the protective frame 302 downward along the slide rails 1001 on the fermentation chamber 1, moving the protective frame 302 onto the corresponding receiving cloth 102 and fitting it onto the connecting plate 10201 on the receiving cloth 102. The protective frame 302, with its wide top and narrow bottom shape, intercepts flying tea leaves, further enhancing the practicality of the present invention.

[0043] Example 2

[0044] On the basis of Example 1, Figure 7 and Figure 8 As shown, it also includes a first electric push rod 401, a first fixed plate 402, a second fixed plate 403 and a second electric push rod 404; the lower side of the connecting plate 10201 on each receiving cloth 102 is bolted to a first electric push rod 401; the telescopic end of each first electric push rod 401 is bolted to a first fixed plate 402, and the first fixed plates 402 located on the same layer are jointly fixed to the receiving cloth 102; each receiving cloth 102 is fixed to a second fixed plate 403; each receiving cloth 102 is bolted to two second electric push rods 404, and the two second electric push rods 404 are jointly connected to the second fixed plate 403.

[0045] It also includes a swivel 10101; three swivels 10101 are provided on each suspension rod 101; the swivels 10101 on the suspension rod 101 enable the receiving cloth 102 and the parts connected thereto to rotate on the suspension rod 101, thereby facilitating the workers to process the tea leaves on the receiving cloth 102.

[0046] 102 ; Step 5: The center of the receiving cloth 102 is driven upward by the moving block 103, so that the receiving cloth 102 is in a state of being high around the bottom in the center, so that the tea leaves are gathered; Step 2: The protective frame 302 is driven by the second electric slider 301 to move along the slide rail 1001 on the fermentation cabinet 1, and the protective frame 302 is put on the connecting plate 10201; Step 3: The workers turn over the gathered tea leaves, and after turning over, the workers evenly spread the tea leaves on the receiving cloth 102 for fermentation; Step 4: After the tea leaves are fermented, the first fixed plate 402 is driven by the first electric push rod 401 and the second electric push rod 404 drives the second fixed plate 403 to move, so that the receiving cloth 102 is flush with the upper end of the connecting plate 10201; Step 5: The center of the receiving cloth 102 is driven upward by the moving block 103, so that the receiving cloth 102 is in a state of being high in the center and low around the sides, and then the workers remove the tea leaves on the receiving cloth 102.

[0047] After the fermentation of the tea leaves in the fermentation cabinet 1 is completed, the tea leaves need to be removed from the receiving cloth 102. Therefore, when the tea leaves need to be removed, the first electric push rod 401 on the connecting plate 10201 pushes the corresponding first fixed plate 402 upward, and at the same time, the second electric push rod 404 drives the second fixed plate 403 to move upward, so that the first fixed plate 402 and the second fixed plate 403 drive the receiving cloth 102 to move upward. When the first fixed plate 402 and the second fixed plate 403 move to the same level as the upper side of the connecting plate 10201 on the receiving cloth 102, they will stop moving, and the receiving cloth 102 will also be flush with the upper side of the connecting plate 10201 at this time. A worker places the collection tray under the receiving cloth 102, and then uses the first electric slider 10301 on the moving block 103 to move upward along the track 10102 on the suspension rod 101, thereby driving the slide bar 10401 on the connecting rod 104 to move along the slide groove 10601 on the expansion rod 106, thereby making the receiving cloth 102 appear higher in the middle and lower around. The worker then removes the tea leaves from the receiving cloth 102. During this process, the worker can also use the rotating ring 10101 on the suspension rod 101 to simultaneously rotate the receiving cloth 102 and its connected parts, further facilitating the worker's removal of the tea leaves from the receiving cloth 102.
