[0023] Please refer to Figure 1 and Figure 2The tea powder storage device comprises a storage tank 1, wherein the storage tank 1 has a storage cavity 11 for accommodating tea powder, and a feed port 12 is provided on the top of the storage tank 1 and is connected to the storage cavity 11, and tea powder can be poured into the storage cavity 11 from the feed port 12. A vertical discharge channel 13 is also provided in the storage tank 1, and the bottom of the discharge channel 13 is connected to the storage cavity 11, and a discharge pipe 14 is also provided on the storage tank 1 and is connected to the top of the discharge channel 13, and one end of the discharge pipe 14 away from the discharge channel 13 extends downward in the vertical direction, and a plurality of baffle plates 15 are staggered on the inner wall of the discharge pipe 14 in the vertical direction, and the height of the end of the baffle plate 15 connected to the inner wall of the discharge pipe 14 is higher than that of the baffle plate 15. The plate 15 is at a height at which one end of the inner wall of the discharge pipe 14 is away from the plate 15. The storage tank 1 is also provided with a spiral conveying component 2, which extends into the discharge channel 13 and conveys the material in the storage chamber 11 to the discharge pipe 14. The spiral conveying component 2 transports the tea powder in the storage chamber 11 along the discharge channel 13 to the discharge pipe 14, and then the tea powder is discharged along the discharge pipe 14 under the action of gravity, so that the tea powder in the tea powder storage device can be taken out.

[0024] Specifically, the operation steps of storing and taking out tea powder using the tea powder storage device provided in this embodiment are as follows: when storing tea powder, pour the tea powder into the storage cavity 11 from the feed port 12, and the tea powder can be stored in the tea powder storage device; when taking out tea powder, place the container for receiving tea powder below the opening of the discharge pipe 14, open the spiral conveying assembly 2, and the spiral conveying assembly 2 lifts the tea powder in the storage cavity 11 along the discharge channel 13 to the discharge pipe 14, so that the tea powder enters the discharge pipe 14 and is discharged under the influence of gravity. The tea powder is discharged along the discharge pipe 14 under the action of the spiral conveying assembly 2, and the spiral conveying assembly 2 can continuously transport the tea powder from the storage chamber 11 to the discharge pipe 14, so as to prevent the tea powder from accumulating in the storage chamber 11 and causing the discharge channel 13 to be blocked. At the same time, when the tea powder falls in the discharge pipe 14, it contacts the baffle plates 15 arranged in a vertical direction in the discharge pipe 14 respectively, so as to slow down the falling speed of the tea powder and guide the tea powder to be discharged from the opening of the discharge pipe 14 through the baffle plates 15, so as to prevent the tea powder from leaving the discharge pipe 14 and scattering into the surrounding environment. The tea powder storage device provided in this embodiment can ensure that the tea powder in the storage tank 1 is discharged smoothly, prevent the tea powder from agglomerating and clogging the discharge channel 13, and at the same time guide the tea powder to fall in the discharge pipe 14 through the baffle plates 15, so as to prevent the tea powder from scattering into the surrounding environment after leaving the discharge pipe 14, and ensure that the tea powder falls into the receiving container to reduce the loss of the product.

[0025] like Figure 2As shown, a feed hopper 3 is further provided on the storage tank 1, and the feed hopper 3 communicates with the feed inlet 12. By providing the feed hopper 3 communicating with the feed inlet 12 on the storage tank 1, pouring tea powder into the feed hopper 3 can enable the tea powder to enter the storage cavity 11 through the feed inlet 12 under the guidance of the feed hopper 3, facilitating the loading of the tea powder into the tea powder storage device.

[0026] Specifically, a detachable cover 31 is provided on the feed hopper 3, and the cover 31 covers the opening of the feed hopper 3. By installing the detachable cover 31 on the feed hopper 3 to close the opening of the feed hopper 3, the storage cavity 11 can be separated from the external environment, preventing sundries such as dust in the surrounding environment from falling into the storage cavity 11 from the feed hopper 3 and contaminating the products in the tea powder storage device. And when it is necessary to pour tea powder into the storage tank 1, just remove the cover 31, which is simple to operate.

[0027] As Figure 2 shown, the storage tank 1 has a jacket 16. The jacket 16 is arranged at an interval from the storage cavity 11 and a cooling medium is filled in the jacket 16. An inlet 17 and a drain 18 respectively communicating with the jacket 16 are provided on the storage tank 1. By connecting the inlet 17 and the drain 18 to external pipelines, the cooling medium in the jacket 16 can circulate in the jacket 16, thereby taking out the heat of the tea powder in the storage tank 1 from the storage cavity 11 and cooling the tea powder, keeping the tea powder in the tea powder storage device at a suitable storage temperature and preventing the tea powder from deteriorating during storage.

[0028] Please refer to Figure 1 and Figure 2 , the screw conveyor assembly 2 includes a first motor 21 and a conveying rod 22 arranged at the output end of the first motor 21. The conveying rod 22 is rotatably arranged on the storage tank 1 and extends into the discharge channel 13, and a screw blade 23 is provided on the part of the conveying rod 22 located in the discharge channel 13. Driving the conveying rod 22 to rotate by the first motor 21 can drive the screw blade 23 to rotate. By the rotation of the screw blade 23, the tea powder entering the discharge channel 13 can be lifted and transported in the vertical direction into the discharge pipe, ensuring the continuous and stable discharge of the tea powder in the storage cavity 11 from the discharge pipe 14, which is beneficial to improving the reliability of the tea powder storage device.

[0029] Please combine Figure 1 and Figure 2The storage tank 1 is also provided with a stirring assembly 4, which includes a second motor 41 and a stirring rod 42 arranged at the output end of the second motor 41. The stirring rod 42 is rotatably arranged on the storage tank 1 and extends into the storage cavity 11, and a stirring paddle 43 is arranged on the portion of the stirring rod 42 extending into the storage cavity 11. The stirring rod 42 is driven to rotate by the second motor 41, which can drive the stirring paddle 43 to rotate in the storage cavity 11, and the agglomerated tea powder is dispersed through the contact between the stirring paddle 43 and the tea powder, so as to avoid the agglomeration of the tea powder during the storage process and affect the product quality. At the same time, the agglomerated tea powder can be prevented from clogging the connection between the storage cavity 11 and the discharge channel 13, so as to ensure the stable operation of the tea powder storage device.

[0030] Specifically, the stirring rod 42 is provided with a plurality of stirring paddles 43 at intervals along the axial direction of the stirring rod 42, and each stirring paddle 43 includes a plurality of stirring blades 44 arranged at intervals along the circumferential direction of the stirring rod 42. By providing a plurality of stirring paddles 43 on the stirring rod 42, the plurality of stirring paddles 43 rotate simultaneously under the drive of the stirring rod 42 to stir and break up the tea powder at different heights in the storage chamber 11, and each stirring paddle 43 includes a plurality of stirring blades 44, and the stirring blades 44 act on the tea powder at the same time during the rotation of the stirring rod 42, thereby further improving the stirring effect of the stirring component 4.

[0031] like Figure 1 and Figure 3 As shown, the storage tank 1 is also provided with a movable baffle 5 that can be lifted and lowered in the vertical direction and a driving assembly 6 that is transmission-connected to the movable baffle 5 . The movable baffle 5 extends into the storage cavity 11 and separates the storage cavity 11 from the discharge channel 13 . The movable baffle 5 arranged on the storage tank 1 is used to separate the storage chamber 11 from the discharge channel 13, so that the storage chamber 11 of the tea powder storage device remains closed when not discharging, thereby preventing moisture in the external environment from entering the storage chamber 11 through the discharge pipe 14 and the discharge channel 13 to adversely affect the quality of the tea powder product. When discharging is required, the driving component 6 drives the movable baffle 5 to descend in the vertical direction and partially withdraw from the storage chamber 11, so that the storage chamber 11 and the discharge channel 13 are connected. At this time, the tea powder in the storage chamber 11 enters the discharge channel 13 under the action of gravity. After discharging is completed, the driving component 6 drives the movable baffle 5 to rise in the vertical direction to separate the storage chamber 11 from the discharge channel 13 again.

[0032] Specifically, a support frame 7 is provided at the bottom of the storage tank 1. A chute 71 that cooperates with the movable baffle 5 is provided on the support frame 7. The storage tank 1 is provided with a slot through which the movable baffle 5 passes, and the slot communicates with the chute 71. By providing the support frame 7 at the bottom of the storage tank 1 and providing the chute 71 that cooperates with the movable baffle 5 on the support frame 7 to guide the support frame 7 to slide in the vertical direction, and when the movable baffle 5 slides in the chute 71, it remains in the slot to prevent the movable baffle 5 from deviating from the preset direction when it moves, ensuring that the storage cavity 11 and the discharge channel 13 are separated after the movable baffle 5 is reset.

[0033] As Figure 3 shown, in this embodiment, the driving assembly 6 includes a third motor 61 and a lead screw 62 provided at the output end of the third motor 61. The axial direction of the lead screw 62 is the vertical direction, and the lead screw 62 is rotatably provided on the storage tank 1. A threaded hole that cooperates with the lead screw 62 is provided on the movable baffle 5. By driving the lead screw 62 to rotate by the third motor 61, the movable baffle 5 can be driven to move along the axial direction of the lead screw 62 through the cooperation of the lead screw 62 and the threaded hole, so as to adjust the position of the movable baffle 5 in the vertical direction, so as to control the movable baffle 5 to move to connect the storage cavity 11 and the discharge channel 13 or block the storage cavity 11 and the discharge channel 13, facilitating the operation of the tea powder storage device.
