Description

Technical Field

[0001] The invention relates to the technical field of tea fermentation, in particular to a tea fermentation machine for tea processing. Background Art

[0002] Tea fermentation is a key step in the tea processing process. Fermentation can change the chemical composition of tea and form a unique aroma, color and taste. Traditional tea fermentation methods mostly use static fermentation, that is, the tea leaves are piled in a fermentation room or fermentation box and fermented by controlling the temperature and humidity. However, this method has some shortcomings, such as uneven fermentation, low efficiency, easy agglomeration, etc., which affect the quality and production efficiency of tea.

[0003] For example, a tea fermentation machine is disclosed in the publication number CN 116035083 A, which relates to the technical field of tea fermentation. The present invention comprises two support plates, and a stirring barrel is rollingly fitted on the upper part of the two support plates. A feed port is provided on the peripheral side of the stirring barrel, and a circular arc-shaped sealing plate is slidingly fitted thereon. The circular arc-shaped sealing plate corresponds to the feed port, and a plurality of through holes are provided inside the stirring barrel and the circular arc-shaped sealing plate. The present invention facilitates the control of the opening and closing of the feed port by means of the circular arc-shaped sealing plate slidingly fitted on the outer side of the stirring barrel, thereby facilitating the addition or removal of tea leaves into or from the stirring barrel. The stirring barrel and the rotating rod rotate in opposite directions to facilitate the fermentation of the tea leaves. The water outlet holes on the peripheral side of the rotating rod facilitate the spraying of fermentation liquid onto the surface of the tea leaves in the stirring barrel, thereby accelerating the fermentation process of the tea leaves. The cleaning mechanism facilitates the stirring of the tea leaves, and the tea leaves adhering to the inner wall of the stirring barrel can be cleaned off at the same time.

[0004] However, the above-mentioned tea fermentation machine blocks both sides of the drum when fermenting tea, which affects the ventilation of the tea, thereby reducing the internal oxygen content of the tea during fermentation, affecting the aerobic fermentation effect of the tea.

[0043] The present invention adopts the above technical solution to bring the following beneficial effects:

[0044] 1.

[0045] 2. The tea fermentation machine used for tea processing uses an air inlet mechanism to drive the blades to rotate using a high-speed rotating motor, and sends air into the interior of the inner rotating cylinder to increase the oxygen content entering the inner rotating cylinder, thereby increasing the oxygen concentration during tea fermentation.

[0046] 3. The tea fermentation machine used for tea processing, through the setting of the turning component, uses the speed reducer to reduce the speed and drive the rotating shaft to rotate, so as to drive the inner rotating cylinder to rotate, so that the tea leaves can be turned through the turning component to promote the full contact between the tea leaves and oxygen, and improve the fermentation effect. At the same time, a movable arc plate is used to expand the turning area and increase the contact area with the tea leaves, thereby increasing the turning quantity of the tea leaves in a single turning, and the arc plate is contracted to push the tea leaves on the arc plate inward, so as to more stably follow the arc plate and the inner rotating cylinder to rotate and turn.

[0047] 4. The tea fermentation machine used for tea processing, through the setting of the pushing component, uses the movable pushing rod to move. On the one hand, it can go deep into the through hole to push the tea leaves attached to the inner side of the through hole to prevent the tea leaves from adhering to the through hole, thereby affecting the rotation and ventilation of the tea leaves. On the other hand, it can push the arc push rod to move, so as to push the arc plate to move, so as to achieve the purpose of better tossing the tea leaves.

[0048] 5. The tea fermentation machine used for tea processing has a feed hopper that can move left and right, which can continuously move the feed hopper left and right to promote the feeding of tea and avoid tea clogging in the feed hopper.

[0060] See also Figure 1-9 One embodiment of the present invention is: a tea fermentation machine for tea processing, comprising an outer rotating drum 1, and further comprising:

[0061] Two fixing rings 2 are installed on the left and right sides of the inner wall of the outer rotating cylinder 1;

[0062] The inner rotating cylinder 3 is mounted on the inner wall of the fixed ring 2 and is used for rotating and turning the tea leaves;

[0063] Two sets of support frames 4 are respectively fixedly connected to the fixing rings 2 on both sides;

[0064] The unloading plate 5 is arranged in an arc shape and is fixedly connected to the right support frame 4 for unloading tea leaves;

[0065] A feed hopper 6 is provided on the left side of the outer rotating cylinder 1 and is used to add tea leaves into the inner rotating cylinder 3;

[0066] The air inlet mechanism 7 is arranged on one side of the left fixed ring 2 and is used to supply air into the inner rotating cylinder 3;

[0067] Among them, two connecting rings 11 are fixedly connected to the left and right sides of the inner ring of the outer rotating cylinder 1;

[0068] Two connecting rings 31 are fixedly connected to the left and right sides of the outer wall of the inner rotating cylinder 3;

[0069] The inner and outer rings of the two fixing rings 2 are respectively provided with an annular groove 21, and a plurality of rollers 22 are respectively installed in the annular groove 21;

[0070] The connecting ring 11 and the connecting ring 2 31 are respectively connected to the fixing ring 2 and rotated through the roller 22;

[0071] The outer wall of the left connecting ring 11 is fixedly connected with the inner gear ring 8, the outer wall of the left connecting ring 2 31 is fixedly connected with the outer gear ring 10, the outer wall of the left fixed ring 2 is installed with a gear 9, the inner gear ring 8, the gear 9 and the outer gear ring 10 are meshed with each other, and the inner rotating cylinder 3 and the outer rotating cylinder 1 rotate in opposite directions.

[0072] Working principle: When tea leaves are fermented, the tea leaves are passed through the feed hopper 6 and then enter the inner rotating cylinder 3 through the feed hopper 6. At this time, the inner rotating cylinder 3 is rotated and the outer gear ring 10 is rotated to drive the gear 9 to rotate in the opposite direction. The rotation of the gear 9 will drive the inner gear ring 8 to rotate in the opposite direction, generating a planetary gear rotation structure, so that the outer gear ring 10 will rotate in the opposite direction relative to the inner gear ring 8. At this time, the rotation directions of the inner rotating cylinder 3 and the outer rotating cylinder 1 will be opposite, so that the tea leaves entering the inner rotating cylinder 3 will be rotated and thrown, avoiding uneven fermentation, low efficiency, and easy agglomeration of the tea leaves, so as to improve the quality and production efficiency of the tea leaves.

[0073] See also Figure 1-9 Based on the above embodiment, in another embodiment of the present invention, preferably, the air inlet mechanism 7 includes:

[0074] The reducer 74 is fixedly mounted on the left support frame 4;

[0075] The ventilation hood 72 is fixedly connected to the left side of the speed reducer 74;

[0076] The motor 71 is fixedly connected to the left side of the ventilation cover 72, and the output shaft of the motor 71 movably passes through the ventilation cover 72 and extends into the reducer 74;

[0077] The blades 73 are fixedly mounted on the outer wall of the output shaft of the motor 71 and are located inside the ventilation cover 72 for supplying air to the interior of the inner rotating cylinder 3 .

[0078] Working principle: At this time, the blade 73 is driven to rotate at a high speed by starting the motor 71, so that wind can be sent into the inner rotating cylinder 3 to increase the oxygen content entering the inner rotating cylinder 3, thereby increasing the oxygen concentration during tea fermentation;

[0079] At the same time, the speed is reduced through the reducer 74 to drive the rotating shaft 33 to rotate, so as to achieve the purpose of rotating the inner rotating cylinder 3 at a low speed.

[0080] See also Figure 1-9 On the basis of the above embodiment, in another embodiment of the present invention, preferably, the two support frames 4 are rotatably connected with a rotating shaft 33, and the left side of the rotating shaft 33 is connected to a reducer 74 for reducing the rotation speed of the rotating shaft 33;

[0081] Two fixing rods 32 are fixedly connected to the right outer wall of the rotating shaft 33, and the fixing rods 32 are fixedly connected to the inner wall of the inner rotating cylinder 3 to drive the inner rotating cylinder 3 to rotate;

[0082] The inner wall of the inner rotating cylinder 3 is provided with a plurality of turning components 34 for turning the tea leaves during rotation;

[0084] Preferably, the turning assembly 34 comprises:

[0085] A fixed plate 342, fixedly connected to the inner wall of the inner rotating cylinder 3;

[0086] The arc-shaped plate 341 is movably connected to the outer wall of the fixed plate 342, and is used to move the tea leaves to rotate around the inner rotating cylinder 3 when rotating;

[0087] A plurality of fixed cylinders 343 are respectively fixedly connected to the inner wall of the inner rotating cylinder 3 and the circular grooves opened on the fixed plate 342;

[0088] A plurality of movable rods 344 are respectively movably sleeved on the outer wall of the fixed cylinder 343 and fixedly connected to the arc plate 341;

[0089] A plurality of springs 345 are respectively fixedly connected to the inner rotating cylinder 3 and the movable rod 344 to pull the movable rod 344 and the arc plate 341 toward the inner wall of the inner rotating cylinder 3 .

[0090] Working principle: when the rotating shaft 33 is driven to rotate by the speed reducer 74, the two fixed rods 32 are directly used to drive the inner rotating cylinder 3 to rotate, and the tea leaves inside the inner rotating cylinder 3 are turned over by the turning assembly 34, and roll around the inner rotating cylinder 3 inside, and after reaching a high place, they are separated from the turning assembly 34 under the action of gravity, and fall back to the bottom of the inner wall of the inner rotating cylinder 3, and when falling, they hit the rotating spiral plate 35, so that the tea leaves are slowly spirally discharged to the right side, so as to achieve the effect of throwing the tea leaves outward;

[0091] When the inner rotating cylinder 3 rotates, after the pushing component 24 contacts the arc push rod 346, the arc plate 341 will be pushed to move outward on the fixed plate 342, thereby expanding the turning area to increase the number of tea leaves turned over in a single time. At the same time, after the pushing component 24 no longer contacts the arc push rod 346, the arc plate 341 will move inward on the fixed plate 342. At this time, the movable rod 344 is pulled into the fixed plate 342 by the spring 2 345, and the arc plate 341 will be pulled to contract, thereby pushing the tea leaves on the arc plate 341 inward, so as to more stably follow the arc plate 341 and the inner rotating cylinder 3 to rotate and turn.

[0092] See also Figure 1-9 , based on the above embodiment, in another embodiment of the present invention, preferably, a mounting rod 23 is fixedly connected between the two fixing rings 2, and a plurality of pushing components 24 are arranged on the mounting rod 23;

[0095] Preferably, each pushing assembly 24 comprises:

[0096] A push rod 241 is movably connected to the mounting rod 23;

[0097] The limiting ring 243 is fixedly connected to the outer wall of the push rod 241, and the outer wall of the push rod 241 is sleeved with a spring 242, and the spring 242 is respectively connected between the limiting ring 243 and the mounting rod 23, and is used to pull the limiting ring 243 and the push rod 241 away from the through hole;

[0098] The arc-shaped inner wall of the arc-shaped plate 341 is fixedly connected with three arc-shaped push rods 346 which are arranged at equal intervals. The other side of the arc-shaped push rods 346 extends into the inner wall of the through hole and fits with the side of the push rod 241 away from the mounting rod 23 to push the arc-shaped plate 341 to move.

[0099] Working principle: When the outer rotating cylinder 1 is driven to rotate in the reverse direction, it will drive the arc-shaped push plate 12 to rotate, so that it will squeeze one side of the push rod 241 during rotation. At this time, the push rod 241 is pushed to move by squeezing, and the other side of the push rod 241 will extend into the through hole to push the tea leaves attached to the inside of the through hole, so as to prevent the tea leaves from being attached to the through hole, thereby affecting the rotation and ventilation of the tea leaves;

[0100] At the same time, after the push rod 241 is extended into the through hole, it will contact the arc push rod 346 to push the arc plate 341 to move. After the arc push plate 12 is separated from the contact with the push rod 241, the push rod 241 will be pushed by the spring 242 to drive the limit ring 243 and the push rod 241 to move outward to achieve the purpose of resetting, so that the gaps between the through holes can be opened to achieve ventilation and increase the oxygen intake during tea fermentation.

[0101] See also Figure 1-9 On the basis of the above embodiment, in another embodiment of the present invention, preferably, one side of the feed hopper 6 is fixedly connected with a plurality of telescopic rods 61, and the other side of the telescopic rods 61 is fixedly connected to the outer wall of the left fixed ring 2;

[0102] An annular baffle 63 is fixedly connected to the inner wall of the left inner rotating cylinder 3 to prevent tea leaves from falling out of the inner rotating cylinder 3 from the left side; a limiting block 64 is fixedly connected to the left side of the annular baffle 63; a spherical push rod 62 is fixedly connected to the right side of the feed hopper 6, and the spherical push rod 62 is in contact with the limiting block 64.

[0104] Working principle: When the inner rotating cylinder 3 rotates, the annular baffle 63 and the limit block 64 will be driven to rotate synchronously, thereby driving the spherical groove to rotate. When the spherical groove rotates, first, the spherical groove does not contact the spherical push rod 62. After the limit block 64 contacts the spherical push rod 62, it will push the feed hopper 6 to move, and at this time, the telescopic rod 61 will be pulled to the left. Secondly, the spherical groove on the limit block 64 contacts the spherical push rod 62. Under the action of the telescopic rod 61, the feed hopper 6 will be pulled to the right, so that the feed hopper 6 can be continuously moved left and right to promote the discharge of tea and avoid tea from being blocked in the feed hopper 6. At the same time, by continuously swinging left and right, the tea can be gradually thrown into the inner rotating cylinder 3 through the bottom of the feed hopper 6 to avoid accumulation in one place when dropping.

All components not specified in this embodiment can be implemented by existing technologies.
