Description

Technical Field

[0001] This application relates to the field of tea extraction technology, and more particularly to a tea extraction device. Background Technology

[0002] Most existing tea extraction equipment is immersion-type tea extraction equipment. The process involves first putting tea leaves into an extraction tank and pouring in hot water to immerse and extract the tea leaves. After the tea leaves are extracted, the tea soup in the extraction tank is poured into a separation tank to separate the tea leaves and tea soup. The separated tea soup is cooled and then transported to an external tea soup storage device.

[0003] While existing tea extraction equipment can effectively extract tea leaves, it requires multiple components such as extraction tanks and separation vessels to complete the extraction process. This results in bulky equipment, and the extraction tanks cannot be used for production while being cleaned, leading to low efficiency. Furthermore, current extraction methods result in low extraction concentrations, high tea-to-water ratios, and high energy consumption.

[0004] Therefore, existing technologies have shortcomings and need to be improved. Summary of the Invention

[0005] This application provides a tea extraction device to solve the problems of existing tea extraction devices, which, although capable of effectively extracting tea leaves, require multiple devices such as extraction tanks and separation tanks to work together to complete the extraction process, have a large equipment size, and cannot operate while the extraction tank needs cleaning, resulting in low efficiency.

[0006] Firstly, this application provides a tea extraction device, including at least two extraction tanks, a tea supply device, a water supply pipe, and a spray box. The tea supply device is positioned above the extraction tanks, and the spray box is connected to the water supply pipe and movably positioned above the two extraction tanks. A tea water collection pipe is provided at the bottom of each extraction tank, and the tea water collection pipe is equipped with a valve. Before the tea leaves fall into the extraction tanks, the valve is closed. After the tea leaves enter the extraction tanks, hot water enters the spray box through the water supply pipe and is evenly sprayed onto the tea leaves in the extraction tanks to extract the tea. Spray extraction yields a higher product yield than traditional extraction equipment.

[0007] Optionally, the tea supply device includes a feeding pipe, a tea storage box, and a moving track. The tea enters the tea storage box through the feeding pipe, and the tea storage box is movably suspended on the moving track, which is positioned above the extraction tank.

[0008] Optionally, the tea storage box has an opening at the bottom, which is a pull-out type.

[0009] Optionally, the opening is provided with a pull-out plate, with an opening on one side and no opening on the other side; when it is necessary to store tea leaves, the side without opening is positioned at the bottom opening; when it is necessary to unload tea leaves, the pull-out plate is adjusted so that the side with opening is positioned at the opening, so that the tea leaves fall from the opening into the extraction tank.

[0010] Optionally, the adjustment method of the pull-out plate includes any one of manual adjustment, automatic motor control adjustment, or automatic cylinder control adjustment.

[0011] Optionally, a filter screen is provided at the bottom of the extraction tank, and the extraction tanks are arranged side by side in pairs.

[0012] Optionally, the bottom of the extraction tank is provided with a rotating device, and a V-shaped groove is provided below the rotating device. After the tea water is collected, the extraction tank is rotated to pour the extracted tea leaves into the V-shaped groove.

[0013] Optionally, the bottom of the V-shaped groove is provided with a rotary conveyor to discharge tea leaves.

[0014] Optionally, the spray box is configured with dual water channels, one water channel being connected to the water supply pipe and the other water channel being connected to the tea collection pipe.

[0015] Optionally, the tea extraction equipment also includes a tea concentration detection device. When the tea concentration is low, the tea in the tea collection pipe can be sprayed into the extraction tank through the spray box for secondary extraction.

[0016] The technical solutions provided in this application have the following advantages compared with the prior art:

[0017] This application provides a tea extraction device comprising at least two extraction tanks arranged side-by-side. When one extraction tank needs cleaning, the other can be used for extraction, allowing the production line to operate continuously and improving production efficiency. A tea supply device is located above the extraction tanks. This device includes a feeding pipe, a tea storage box, and a moving track. Tea leaves enter the tea storage box through the feeding pipe, and the tea storage box is movably suspended on the moving track, which is positioned above the extraction tanks. An opening is provided at the bottom of the tea storage box. After the tea storage box is filled with tea leaves at the feeding pipe, it moves along the moving track above the extraction tank requiring feeding, and then the opening at the bottom of the tea storage box is opened to place the tea leaves into the extraction tank.

[0018] The tea extraction setup also includes a spray box positioned above the extraction tanks and movable between them. When one extraction tank needs tea feeding, the spray box can be moved to the other extraction tank, and then moved back after feeding. When the spray box needs to be moved, a cylinder drives it to move along tracks at both ends of the extraction tanks.

[0019] By setting up multiple extraction tanks and movable spray boxes, continuous production of the tea extraction line was achieved, avoiding production interruptions caused by cleaning the extraction tanks and improving production efficiency.

[0020] Automated production can automatically complete tasks such as tea feeding, spray box movement, and tea pouring after extraction, saving labor costs. Attached Figure Description

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0030] The following disclosure provides numerous different embodiments or examples for implementing various structures of this application. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of this application. Furthermore, reference numerals and / or letters may be repeated in different examples.

Therefore, the example term "below" can include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions), and the spatial relative descriptors used in the text will be interpreted accordingly.

[0032] Figure 1-3A tea extraction device provided in this application includes at least two extraction tanks 4, which are arranged side by side. When one extraction tank 4 needs cleaning, the other extraction tank 4 can be used for extraction, thus allowing the production line to operate continuously and improving production efficiency. A tea supply device is provided above the extraction tanks 4. The tea supply device includes a feeding pipe 2, a tea storage box 1, and a moving track 3. Tea enters the tea storage box 1 through the feeding pipe 2. The tea storage box 1 is movably suspended on the moving track 3, which is positioned above the extraction tanks 4. An opening is provided at the bottom of the tea storage box 1. After the tea storage box 1 is filled with tea at the feeding pipe 2, it moves to the top of the extraction tank 4 that needs to be fed via the moving track 3, and then the opening at the bottom of the tea storage box 1 is opened to place the tea into the extraction tank 4.

[0033] Furthermore, the opening at the bottom of the tea storage box 1 is a pull-out type, with a pull-out plate. One side of the pull-out plate is formed into an opening, and the other side is not formed into an opening. When it is necessary to store tea, the side without an opening is set at the bottom opening. When it is necessary to unload the tea, the pull-out plate is adjusted so that the side with the opening is set at the opening, so that the tea falls from the opening into the extraction tank 4.

[0034] In a specific embodiment, the adjustment method of the pull-out plate includes any one of manual adjustment, automatic adjustment by motor control, or automatic adjustment by cylinder control. That is, the pull-out plate can be adjusted manually or automatically by motor or cylinder.

[0035] refer to Figure 3 The tea extraction equipment also includes a water supply pipe and a spray box 8 connected to the water supply pipe. The water supply pipe is installed on the extraction tank 4 and is used to supply hot water to the spray box 8. The spray box 8 is located above the extraction tank 4 and can move between the two extraction tanks 4. When one extraction tank 4 needs to be filled with tea, the spray box 8 can be moved to the other extraction tank 4, and after the tea is filled, the spray box 8 can be moved back. When the spray box 8 needs to be moved, a cylinder drives the spray box 8 to move along the moving tracks 3 at both ends of the extraction tank 4. The spray box 8 has evenly distributed water holes so that hot water can be sprayed evenly on the tea leaves in the extraction tank 4. A tea water collection pipe is provided at the bottom of the extraction tank 4. The tea water collection pipe is equipped with a valve. Before the tea leaves fall into the extraction tank 4, the valve is closed. After the tea leaves enter the extraction tank 4, hot water enters the spray box 8 through the water supply pipe and is evenly sprayed on the tea leaves in the extraction tank to extract the tea leaves. After extraction, the valve is opened, and the tea water enters the tea water collection pipe of extraction tank 4. After cooling, it is transported to the external tea juice storage device, thus completing the tea extraction. The spray extraction method has a higher product yield than traditional extraction equipment.

[0036] Furthermore, a filter screen is installed at the bottom of the extraction tank 4 to effectively prevent tea leaves from entering the tea water collection pipe.

[0037] In some specific embodiments, a rotating device 7 is provided at the bottom of the extraction tank 4, and a V-shaped groove 5 is provided below the rotating device 7. After the tea water is collected, the extraction tank 4 is rotated to pour the extracted tea leaves into the V-shaped groove 5. Furthermore, a rotating conveying device 6 is provided at the bottom of the V-shaped groove 5 to discharge the tea leaves at the bottom of the V-shaped groove 5.

[0038] The spray box 8 can be configured with dual water channels, one connected to the water supply pipe and the other connected to the tea collection pipe. The tea extraction equipment also includes a tea concentration detection device. When the tea concentration is low, the tea in the tea collection pipe can be sprayed through the spray box 8 into the extraction tank 4 for secondary extraction, thereby increasing the tea concentration.

[0039] By setting up multiple sets of extraction tanks 4 and movable spray boxes 8, continuous production of the tea extraction line was achieved, avoiding production interruptions caused by cleaning the extraction tanks 4 and improving production efficiency.

[0040] Automated production can automatically complete tasks such as tea feeding, spray box movement, and tea pouring after extraction, saving labor costs.

[0041] The working principle and usage of this utility model:

[0042] Step S1: The tea storage box 1 is moved to the bottom of the feeding pipe 2 via the moving track 3, the bottom opening of the tea storage box 1 is closed, and the tea enters the tea storage box 1 through the feeding pipe 2.

[0043] Step S2: After the tea leaves are loaded, the tea storage box 1 is moved above the extraction tank 4 that needs to be filled, and the spray box 8 is moved above the extraction tank 4 on the other side. The valve of the tea water collection pipe is closed. At this time, the opening at the bottom of the tea storage box 1 is opened to allow the tea leaves to enter the extraction tank 4.

[0044] In step S3, the spray box 8 is moved back above the extraction tank 4 and lowered by the cylinder to cover the extraction tank 4.

[0045] Step S4: Hot water enters the extraction tank 4 from the water supply pipe to extract the tea leaves;

[0046] Step S5: After extraction is complete, open the valve of the tea water collection pipe. The tea water enters the tea water collection pipe through the filter screen and flows out of the extraction tank 4.

[0047] Step S6: The tea concentration detection device detects the concentration of the tea. When the tea concentration is low, the tea in the tea collection pipe flows into the spray box 8 through the pump (not shown in the figure), and is evenly sprayed into the extraction tank 4 through the spray holes at the bottom of the spray box 8 for secondary extraction. If the tea concentration is appropriate, the tea is pumped to the external tea juice storage device.

[0048] Step S7: After the tea water flows out for extraction, the cylinder lifts the spray box 8, then the spray box 8 is moved away, the extraction tank 4 is rotated and the extracted tea leaves in the extraction tank 4 are poured into the V-shaped trough 5, and the rotating conveyor device 6 discharges the tea leaves from the bottom of the V-shaped trough 5.

[0049] In step S8, the extraction tank 4 is flipped back to its initial position, and the next round of extraction is performed.

[0050] It should be noted that when extraction tank 4 needs cleaning, the other extraction tank 4 can be used for the operation. There are two sets of tea supply devices, which can feed the two sets of extraction tanks 4 separately. The spray box 8 is movable and can spray the two sets of extraction tanks 4. The V-shaped groove 5 is located below the two sets of extraction tanks 4 and can collect the tea leaves poured out of the two sets of extraction tanks 4.

[0051] Depending on actual needs, this device can also open the valve in the tea water collection pipe when spraying hot water, so as to spray water and discharge material at the same time, thereby reducing the discharge time. For heat-sensitive products, it can preserve the flavor of the product well.
