Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of tea processing, in particular to an intelligent processing device for tea. BACKGROUND

[0002] Tea is a beverage raw material processed from fresh leaves of Camellia sinensis. According to the degree of fermentation, it can be divided into six major tea categories, including green tea, white tea, oolong tea, and black tea. Black tea is a typical fully fermented tea. Fermentation is the core processing link that determines its quality. During the fermentation process, endogenous enzymes in tea catalyze the oxidation and polymerization of polyphenols, causing the tea to gradually change from green to red-brown, and generating characteristic substances such as theaflavins and thearubigins. Ultimately, it forms the quality characteristics of red tea, such as red soup and red leaves, sweet and strong aroma. During the fermentation process, appropriate temperature, humidity, and oxygen conditions need to be maintained to ensure stable enzyme-catalyzed reactions.

[0003] Existing black tea fermentation is mostly completed using box-shaped fermentation devices. For example, a fermentation device for processing black tea and a tea fermentation method using the device are disclosed in Chinese Patent No. CN114831194B. The device achieves uniform tea turning by driving the fermentation box to shake, and the liquid is sprayed into the box by a spraying system. The liquid penetrates into the box through the holes to supplement the humidity of the tea, thereby meeting the humidity requirements of the fermentation process.

[0004] During the fermentation process of black tea, heat is released from the tea, creating a warm microenvironment conducive to enzyme-catalyzed reactions. However, shaking the fermentation box disperses the heat accumulation area, causing the tea temperature to drop, resulting in insufficient or uneven fermentation of the tea. Therefore, in actual operation, the tea is usually only turned and sprayed when the humidity is detected to be uneven. During tea fermentation, the bottom is the initial area of heat generation, and the water vapor diffuses upward and is discharged from the top of the fermentation box. This causes the water vapor replenishment rate at the bottom to be lower than the loss rate, and the humidity gradually decreases. At this time, if the tea is uniformly distributed by overall turning and supplemented with humidity by spraying, it may cause the top tea, which has already met the humidity standard, to absorb too much moisture, leading to excessive humidity and causing problems such as mold growth and over-fermentation of the tea. Therefore, there is an urgent need for an intelligent processing device for tea to solve the above problems. SUMMARY

[0005] The present application provides an intelligent processing device for tea, which intelligently detects and controls the humidity through a humidity sensor. Tea with insufficient humidity can be pushed into separate cavities for individual water replenishment, maintaining balanced humidity in each layer during the fermentation process, allowing the tea to normally generate characteristic components and ensuring fermentation quality. This solves the problems raised in the background art, i.e.:

[0006] When the tea leaves are fermented, the humidity of the bottom part decreases due to the loss of water vapor, and the overall turning and spraying can easily cause the top part of the tea leaves to be too wet, leading to mold and over-fermentation.

[0007] To achieve the above-mentioned purpose, the tea processing device comprises a frame body, a fermentation box and a spraying mechanism installed on the frame body, the fermentation box is installed inside the frame body, and a plurality of ventilation holes are formed on the surface of the fermentation box, a bottom plate is fixedly installed inside the fermentation box, and a fermentation cavity is formed between the bottom plate and the upper end of the inner cavity of the fermentation box, a middle ridge is arranged at the bottom of the inner cavity of the fermentation cavity, and two turning mechanisms capable of sliding inside the fermentation box are symmetrically arranged on both sides of the middle ridge.

[0008] Two vertical partitions are vertically installed inside the fermentation cavity, and a gap exists between the bottom of the two vertical partitions and the bottom plate, so as to divide the fermentation cavity into a main fermentation cavity and two sub-cavities which are connected at the bottom, and the atomizing spray head in the spraying mechanism corresponds to the position of the sub-cavity.

[0009] The top of the middle ridge is embedded with a humidity sensor for detecting the humidity of the tea leaves.

[0010] In the above technical solution, the fermentation cavity is divided into a main fermentation cavity and sub-cavities by the vertical partitions, the tea leaves with insufficient humidity at the bottom of the main fermentation cavity are pushed to the sub-cavities by the directional pushing of the push plate, and the sub-cavities are subjected to zoned humidification by the atomizing spray head corresponding to the position of the sub-cavity, so that the tea leaves with insufficient humidity can only obtain accurate water replenishment in the sub-cavities, while the tea leaves with sufficient humidity at the top of the main fermentation cavity are not affected by the spraying, effectively reducing the problem of excessive humidity caused by overall turning and global spraying, and ensuring the balanced humidity of the tea leaves at each layer.

[0011] On this basis, the inner cavity bottom of the fermentation cavity takes the middle ridge as the highest point, and symmetrical flow guide slopes are provided on both sides, and the inclination angle of the bottom surface of the push plate is matched with the flow guide slope. In this structure, the inclination angle of the bottom surface of the push plate is matched with the flow guide slope, so that the push plate can be attached to the bottom when sliding along the slope, reducing the gap between the push plate and the bottom plate, and the symmetrical flow guide slopes provide guidance for the flow of tea leaves, so that the tea leaves with insufficient humidity pushed by the push plate can smoothly slide to the sub-cavities on both sides along the slope, improving the stability and integrity of the tea leaf pushing, and ensuring that the sub-cavity humidification operation can act on the target tea leaves.

[0012] In addition, the side end of the push plate is connected with a power set, a bottom cavity is formed between the bottom plate and the inner cavity bottom of the fermentation box, and the side of the power set away from the push plate is located inside the bottom cavity.

[0013] The power group comprises a horizontal limiting hole and a directional hole, the horizontal limiting hole is arranged on the inner wall of the bottom cavity, and the directional hole is arranged on the inner wall of the main fermentation cavity and is arranged in an inclined manner, and the inclination angle of the directional hole is matched with the inclination of the flow guide slope;

[0014] The inside of the bottom cavity is provided with a main driving part, the movable end of the main driving part is fixedly connected with an extension rod, both ends of the extension rod are in a bent shape, and the end of the extension rod away from the main driving part penetrates through the horizontal limiting hole and the directional hole in sequence and is connected with the side end of the push plate.

[0015] The bottom cavity provides an independent installation space for the power group, meanwhile, the horizontal limiting hole limits the horizontal movement track of the extension rod, the directional hole arranged in an inclined manner and matched with the flow guide slope guides the extension rod to drive the push plate to slide in a preset direction, and the power transmission of the bent extension rod is combined, so that the driving force of the main driving part can be converted into the stable reciprocating sliding of the push plate, and the precision of the directional tea pushing and the stability of the device operation are improved.

[0016] Furthermore, the inside of the directional hole is connected with a self-sealing strip, and the self-sealing strip can dynamically seal the gap between the directional hole and the extension rod in the sliding process of the extension rod. The self-sealing strip is fixed to the inner wall of the directional hole, the edge thereof is closely attached to the outer wall of the extension rod, and adaptive deformation is generated in the reciprocating sliding of the extension rod by virtue of the elasticity thereof, so as to fill the gap between the two, which can prevent the loose tea and tea powder in the main fermentation cavity from leaking into the bottom cavity through the gap between the directional hole and the extension rod, and meanwhile, the normal sliding track of the extension rod is not disturbed, so that the stability and precision of the movement of the push plate are ensured.

[0017] Compared with the prior art, the beneficial effects of the present application are:

[0018] 1. In the intelligent processing device for tea, when the tea to be fermented is put into the fermentation box, the two push plates are slid to the cavity opening to form a relatively closed space in the main fermentation cavity, so that the tea scattering during tea pouring can be reduced, and the push plates are simultaneously slid to the ridge after tea pouring, so that the tea in the main fermentation cavity can be combed into a loose state, and the overall ventilation effect of the fermentation cavity can be improved in combination with the gap design at the bottom of the vertical partition plate; when the humidity sensor detects that the humidity of the tea at the bottom of the main fermentation cavity is insufficient, the push plates are started again to push the tea at the bottom to the two cavities, and the corresponding atomizing spray heads at the cavity positions are used for targeted humidification, so that the precision of the humidification is effectively improved.

[0019] 2、The intelligent processing device for tea, in the process that the push plate pushes the tea at the bottom of the main fermentation cavity to the cavity, the tea in the main fermentation cavity will naturally fall into the empty area of the lower layer, with the cycle of humidity detection and push plate action, the tea can complete the position exchange of upper and lower layers in the dynamic flow of the main fermentation cavity and the cavity, in this process, the tea can uniformly contact the fermentation environment, and the uniformity of fermentation is improved.

[0034] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0035] When the tea leaves are fermented in the inside of the fermentation box 13, the heat generated at the bottom causes the water vapor to flow out, resulting in a decrease in the humidity at the bottom of the fermentation box 13. If the whole tea leaves are turned over and combined with the water spraying mode, the tea leaves at the top with a standard humidity are likely to absorb too much water, causing problems such as excessive humidity, mold growth and over-fermentation. In view of this, the present application provides an intelligent processing device for tea leaves, as shown in Figures 1-3 The fermentation box 13 is installed in the inside of the shelf body 11, and the surface of the fermentation box 13 is provided with a plurality of ventilation holes, which ensure the air circulation inside and outside the fermentation cavity and meet the oxygen supply required for tea fermentation.

[0036] The inside of the fermentation box 13 is fixedly installed with a bottom plate, the bottom plate and the upper end of the inner cavity of the fermentation box 13 form a fermentation cavity, the inner cavity bottom of the fermentation cavity is provided with a middle ridge 16, the middle ridge 16 serves as a protruding reference at the bottom of the fermentation cavity, provides a guide for the sliding of the push plate 22, and provides an installation position for the humidity sensor 19, so as to facilitate the detection of the humidity of the tea leaves at the bottom of the main fermentation cavity 15. The two sides of the middle ridge 16 are symmetrically provided with two turning mechanisms 2 which can slide in the inside of the fermentation box 13. The turning mechanisms 2 realize the loose combing and directional pushing of the tea leaves through the reciprocating sliding of the push plate 22, and cooperate with the spraying mechanism 12 to complete the accurate humidification. Two vertical partitions 18 are vertically installed in the inside of the fermentation cavity, and there is a gap between the bottom of the two vertical partitions 18 and the bottom plate, so as to divide the fermentation cavity into one main fermentation cavity 15 and two sub-cavities 14 which are connected at the bottom. The humidification operation only acts on the tea leaves in the sub-cavities 14, reducing the problem of excessive humidity caused by global spraying. The atomizing spray head 124 in the spraying mechanism 12 corresponds to the position of the sub-cavity 14, so that the mist liquid can be sprayed into the sub-cavity 14 to uniformly supplement the water for the tea leaves with insufficient humidity. The turning mechanism 2 includes a push plate 22, which can reciprocate along the surface of the bottom plate to push the tea leaves with insufficient humidity at the bottom of the main fermentation cavity 15 to the sub-cavities 14 on both sides.

[0037] Again in combination with Figure 3As shown, the humidity sensor 19 is embedded in the top of the ridge 16, and its installation position is in contact with the tea leaves at the lower end of the main fermentation cavity 15, and the ridge 16 is a protruding structure at the bottom of the fermentation cavity, so that the humidity sensor 19 can detect the humidity data of the tea leaves at the bottom area of the main fermentation cavity 15; As is well known to those skilled in the art, the above-mentioned humidity sensor 19 realizes detection based on the correlation between material moisture content and dielectric constant. Specifically, when the detection end of the humidity sensor 19 is in direct contact with the tea leaves, the moisture in the tea leaves will change the dielectric constant between the two polar plates of the humidity sensor 19. The higher the moisture content, the greater the dielectric constant. The humidity sensor 19 detects the change of the dielectric constant through the built-in circuit, and converts it into a corresponding electrical signal. After signal processing module conversion, the output value can directly reflect the current humidity of the tea leaves.

[0038] If the humidity inside the fermentation box 13 is insufficient, it will cause the endogenous polyphenol oxidase activity of the tea leaves to decrease, and the oxidation and polymerization reaction of polyphenols cannot proceed normally, so the tea leaves are difficult to generate characteristic components such as theaflavins and thearubigins. Therefore, in combination with the above-mentioned humidity sensor 19, the fermentation box 13 is provided with a water supplement structure. Figure 4 As shown, on the rack body 11, a structure capable of supplementing water in the fermentation box 13 is provided, wherein the water tank 121 is a water storage component for water supplement, fixed on the bottom layer of the rack body 11, and the main pipe rack 122 is assembled inside the rack body 11 and communicates with the water tank 121 through a water pump. When the water pump operates, it can transport the liquid in the water tank 121 to the main pipe rack 122. The multiple bifurcations inside the main pipe rack 122 divide the liquid into each lateral bifurcated pipe 123. Each lateral bifurcated pipe 123 is provided with an independent one-way valve (not shown in the figure) inside. The one-way valves on both sides of the same fermentation box 13 form a control unit, and the one-way valves of different groups are electrically connected with the humidity sensor 19. The lateral bifurcated pipes 123 extend along the inside of the rack body 11 to both sides of the fermentation box 13, and the atomizing spray heads 124 installed on the side close to the fermentation box 13 correspond to the positions of the sub-cavities 14 of the fermentation box 13.

[0039] When the humidity sensor 19 detects that the humidity of the tea leaves at the bottom of the main fermentation cavity 15 is insufficient, it will send an electrical signal to the corresponding one-way valve control unit and water pump on the same side: after receiving the signal, the water pump starts to pressurize and transport the liquid in the water tank 121 to the main pipe rack 122, and at the same time, the one-way valve control unit related to the area with insufficient humidity responds to the signal and triggers the corresponding group of one-way valves to open, so that the liquid in the main pipe rack 122 can only flow through the lateral bifurcated pipe 123 on that side. After the liquid is transported to the corresponding atomizing spray head 124 through the lateral bifurcated pipe 123, it is converted into a misty form and enters the sub-cavity 14 through the ventilation hole of the fermentation box 13, completing the directional water supplement operation for the tea leaves in the sub-cavity 14.

[0040] The side end of the push plate 22 is connected with the power group 21, and a bottom cavity 17 is formed between the bottom plate and the inner cavity bottom of the fermentation box 13.

[0041] Before the tea leaves that need to be fermented are put into the fermentation box 13, the main power member 211 (such as adopting a wireless electric push rod structure) is started, the movable end of the main power member 211 drives the telescopic rod 212 to slide in the horizontal limiting hole 213 and the directional hole 214, and the telescopic rod 212 drives the push plate 22 to slide along the guide slope at the bottom of the fermentation cavity simultaneously until the push plate 22 is located at the communication position of the main fermentation cavity 15 and the sub-cavity 14, refer to Figure 5 It can be seen that at this time, the main fermentation cavity 15 forms a relatively independent space, then the tea leaves to be fermented are put into the opening of the main fermentation cavity 15, and the tea leaves fall into the main fermentation cavity 15 under the action of gravity and are naturally accumulated. Since the push plate 22 and the vertical partition plate 18 have formed a block, the tea leaves cannot spread to the two sub-cavities 14 and are concentrated in the main fermentation cavity 15. After the tea putting is completed, the main power member 211 is started again to drive the telescopic rod 212 to extend to the middle ridge 16 direction along the horizontal limiting hole 213 and the directional hole 214 simultaneously. The inclination angle of the directional hole 214 is consistent with the guide slope, which guides the telescopic rod 212 to drive the push plate 22 to slide along the guide slope at the same speed stably. In the sliding process, the push plate 22 can generate a horizontal pushing force on the tea leaves accumulated in the main fermentation cavity 15, which can comb and disperse the tea leaves clumped or compacted at the bottom end of the main fermentation cavity 15, so that uniform gaps are formed between the tea leaves. At this time, the tea leaves in the main fermentation cavity 15 are in a relatively loose state, and air can flow freely through the gaps at the bottom of the vertical partition plate 18 and the gaps between the tea leaves, thereby providing sufficient oxygen for the fermentation process.

[0042] It should be noted that when the push plate 22 moves to the both sides of the middle ridge 16, if the push plate 22 pushes the tea leaves to press against the middle ridge 16, the tea leaves will first contact the flexible connecting plate 23 (such as adopting food-grade silicone material). Due to the flexible material, the damage to the tea leaves caused by the pressing can be reduced.

[0043] The tea leaves start to ferment in a loose state, and the heat released during the fermentation process forms a stable environment in the main fermentation cavity 15. The humidity sensor 19 at the top of the middle ridge 16 is in continuous contact with the tea leaves at the lower end of the main fermentation cavity 15, and the humidity data of the bottom tea leaves are collected in real time. When the humidity sensor 19 detects that the humidity value of the tea leaves at the bottom of the main fermentation cavity 15 is lower than the preset standard, it will send a starting electric signal to the main power member 211, the water pump and the corresponding one-way valve control unit. After receiving the signal, the movable end of the main power member 211 extends, and the telescopic rod 212 drives the push plate 22 to slide along the guide slope to the direction of the two sub-cavities 14 again, as shown in Figure 6 The side surface of the push plate 22 contacts the bottom tea leaves and generates a pushing force, which pushes the tea leaves with insufficient humidity at the bottom of the main fermentation cavity 15 to the two sub-cavities 14 along the guide slope. In this process, the tea leaves in the upper layer of the main fermentation cavity 15 lose the support at the bottom and naturally fall down under the action of gravity, filling the vacancy area left after the bottom tea leaves are pushed, thereby realizing the preliminary position exchange of the tea leaves in the upper and lower layers.

[0044] When the water pump receives the start signal, it is powered on to operate, pressurizes the liquid in the water tank 121, and delivers the liquid to the inside of the main pipe frame 122. The multiple bifurcated flow channels in the main pipe frame 122 uniformly distribute the liquid to the corresponding unidirectional valve control unit of the lateral bifurcated flow pipe 123 and the one-way valve corresponding to the sub-chamber 14 responds to the signal to control the opening of the unidirectional valve on the corresponding side. The liquid is delivered to the atomizing spray head 124 through the lateral bifurcated flow pipe 123, the atomizing spray head 124 atomizes the liquid into fine droplets, and the fine droplets are evenly sprayed into the sub-chamber 14 through the ventilation holes in the side wall of the fermentation box 13. The atomized liquid contacts the tea leaves with insufficient humidity in the sub-chamber 14 to supplement the moisture of the tea leaves. The misty form can reduce the situation that the liquid gathers on the surface of the tea leaves, causing local humidity to be too high. The unidirectional valve is provided with a rated water injection amount.

[0045] During the water replenishment process, the driving force 211 drives the telescopic rod 212 to retract in the opposite direction, driving the push plate 22 to return to the direction of the central ridge 16 along the flow guide slope. During the return process, the side of the push plate 22 contacts the tea leaves in the sub-chamber 14 that have been watered. If the humidity sensor 19 still detects that the tea leaves at the lower end of the main fermentation chamber 15 (the original middle layer of tea leaves) are insufficiently humid, the push plate 22 will repeat the previous pushing action to push the tea leaves at the bottom of the main fermentation chamber 15 into the sub-chamber 14 again. Since the spray position of the atomizing spray head 124 is relatively close to the lower part of the sub-chamber 14, the newly entered tea leaves in the sub-chamber 14 can be directly humidified. As shown in Figure 7 During this process, because new tea leaves enter the sub-chamber 14, the tea leaves that have been humidified in the sub-chamber 14 will be pushed to the upper end of the sub-chamber 14. Combined with the fact that the upper end of the vertical partition plate 18 is inclined to one side of the main fermentation chamber 15, the tea leaves that have been humidified will re-enter the main fermentation chamber 15. This cycle can achieve the exchange of the upper and lower layers of tea leaves in the main fermentation chamber 15.

[0046] It should be noted that due to the use of atomizing humidification, the tea leaves in the sub-chamber 14 are in a fluffy state. When new tea leaves are pushed into the sub-chamber 14, the original tea leaves will be pushed upwards and re-enter the main fermentation chamber 15 along the inclined direction of the vertical partition plate 18.

[0047] Because the telescopic rod 212 needs to pass through the horizontal limiting hole 213 and the directional hole 214 to connect with the push plate 22, due to the setting of the hole position and the loose state of the tea leaves in the main fermentation chamber 15, part of the tea leaves may leak out during the fermentation of the tea leaves and the sliding process of the push plate 22. Therefore, in order to reduce the leakage of tea leaves, please refer to Figure 8 and Figure 9As shown, the inside of the directional hole 214 is connected with a self-sealing strip 215, the inside edge of which is tightly attached to the outer wall of the telescopic rod 212, and the self-sealing strip 215 is made of elastic material (such as rubber material). When the telescopic rod 212 reciprocally slides along the horizontal limiting hole 213, the self-sealing strip 215 can adaptively deform with the movement of the telescopic rod 212, always keep the attached state with the outer wall of the telescopic rod 212, and fill the gap between them without affecting the normal sliding track of the telescopic rod 212.

[0048] The side of the push plate 22 attached to the bottom plate is paved with a friction-resistant film (such as a food-grade polytetrafluoroethylene film) made of high wear-resistant material, the surface of which directly contacts the bottom plate, which can reduce the friction coefficient between the push plate 22 and the bottom plate when the push plate 22 slides, and reduce the wear caused by the long-term contact and sliding between them. The other two sides of the push plate 22 are covered with flexible silicone covers, which can reduce the breakage of tea caused by the direct contact of the hard edges of the push plate 22 with the tea, and at the same time, the silicone covers can form a flexible attachment with the vertical partition plate 18 or the inner wall of the fermentation box 13 during the sliding process of the push plate 22, improving the integrity of the tea pushing process.

[0049] It should be noted that the silicone cover, flexible connecting plate 23, self-sealing strip 215 and vertical partition plate 18 themselves or the materials paved on their surfaces all meet the food-grade standard.

[0050] In Figure 5 the arrow indicates the direction of tea input, in Figure 6 the arrow indicates the pushing direction of the push plate 22, and in Figure 7 the arrow indicates the sliding direction of the tea being pushed.

[0051] Working principle:

[0052] When the device is working, the main fermentation cavity 15 is first closed by the push plate 22, so as to facilitate the input of tea and make it accumulate, after the tea is input, the push plate 22 slides towards the ridge 16 to comb the tea, so as to make it loose for ventilation and fermentation. In the fermentation process, the humidity sensor 19 at the top of the ridge 16 detects the humidity of the tea at the bottom of the main fermentation cavity 15 in real time. When the humidity is insufficient, the driving force 211 is driven to make the push plate 22 slide, pushing the tea at the bottom of the main fermentation cavity 15 towards the sub-cavity 14. At this time, because the bottom tea moves, the upper tea will fall and fill the position of the original bottom tea, and at the same time, the spraying mechanism 12 starts to work, and the one-way valve controls the water supply of the atomizing spray head 124 corresponding to the sub-cavity 14.

[0053] If there is still tea with insufficient humidity at the bottom of the main fermentation cavity 15, the pushing and water supply operation is repeated. When the new tea enters the sub-cavity 14, it will push the original water-supplied tea to flow back to the main fermentation cavity 15 along the inclined vertical partition plate 18, realizing the up-down circulation and exchange of the tea.
