[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0018] Example 1
[0019] See also Figure 1-7 A raw tea rehydration device comprises a stirring mechanism 1, a spray mechanism 2 located above the stirring mechanism, and a weighing mechanism 3 located below the stirring mechanism. The stirring mechanism 1 is provided with an arc door 11, and the arc door 11 is located at the bottom of the stirring mechanism 1. The arc door 11 is slidable and hollowed out. When the raw tea is rehydrated, the arc door 11 is tightly closed, and water can flow out from the hollowing. When the raw tea is rehydrated, the arc door 11 is opened to allow the raw tea to fall onto the weighing mechanism 3, and the moisture content of the raw tea is measured by the weighing mechanism 3.
[0020] In actual use, the staff pours the raw tea into the stirring mechanism 1, and then starts to rehydrate the raw tea. The raw tea is located in the stirring mechanism 1, and water is added under the spray of the spray mechanism 2, and is stirred by the stirring mechanism 1 to ensure that the raw tea is evenly rehydrated. When the raw tea is rehydrated, the arc door 11 can prevent the raw tea from falling and can also drain the water, thereby avoiding water accumulation in the raw tea. When the initially calculated water content is consumed, the first rehydration of the raw tea is completed. At this time, the frame for collecting the raw tea is placed on the weighing mechanism 3, and the arc door 11 is opened. The rehydrated raw tea will fall from the arc door 11 to the frame for collecting the raw tea, and the weight after rehydration is measured by the weighing mechanism 3, and then compared with the weight of the raw tea before rehydration to obtain the moisture content of the raw tea after rehydration. When the moisture content is not within the range of 25-35tw%, the raw tea in the frame is poured back into the stirring mechanism 1 to continue rehydration until the moisture content of the raw tea is within the range of 25-35tw%.
[0021] Furthermore, the spray mechanism 2 includes a water storage unit 21, a water pipe 22, and a spray unit 23. One end of the water pipe 22 is located in the water storage unit 21. The water pipe 22 is rotatably connected to the spray unit 23. The spray unit 23 is located above the stirring mechanism 1.
[0022] In this embodiment, the water pipe 22 transports the water in the water storage unit 21 to the spray unit 23, and then the water is sprayed into the stirring mechanism 1 through the spray unit 23. In particular, the rotatable connection between the water pipe 22 and the spray unit 23 can facilitate the staff to pour the raw tea into the stirring mechanism 1.
[0023] Furthermore, the spray unit 23 includes a connecting plate 231 and a plurality of spray heads 232. The connecting plate 231 is connected to the water pipe 22 and is located above the stirring mechanism 1. The plurality of spray heads 232 are connected to the connecting plate 231. The connecting plate 231 can drive the spray heads 232 to swing toward the outside or inside of the stirring mechanism 1.
[0024] Through the above design, when the staff pours the raw tea into the stirring mechanism 1, the connecting plate 231 is swung toward the outside of the stirring mechanism 1, which is convenient for the staff to pour the raw tea. When rehydration is required, the connecting plate 231 is swung toward the inside of the stirring mechanism 1 to avoid water loss.
[0025] Preferably, the stirring mechanism 1 includes a stirring box 12 and a stirring unit 13. The stirring box 12 is located below the connecting plate 231. The weighing mechanism 3 is located below the stirring box 12. The stirring unit 13 is rotatably connected in the stirring box 12. A groove 121 is provided at the bottom of the stirring box 12. The arc door 11 is slidably connected in the groove 121.
[0026] In the present embodiment, the raw tea is rehydrated in the mixing box 12. During the rehydration, the raw tea is stirred by the stirring unit 13, and water is sprayed into the mixing box 12 by the spray head 232 during the stirring process to ensure that the water transported by the water pipe 22 enters the mixing box 12. Specifically, the arc door 11 can slide along the groove 121, which is convenient for the staff to operate the arc door 11 and control the arc door 11 to be in an open or closed state.
[0027] More preferably, there are two arc-shaped doors 11 , and the arc-shaped doors 11 are symmetrically connected to the bottom of the mixing box 12 .
[0028] In this embodiment, there are two arc-shaped doors 11, which can improve space utilization, make the opened space larger, and expand the space for tea leaves to fall.
[0029] Furthermore, the stirring unit 13 includes a driving motor 131 and a stirring roller 132 . The stirring roller 132 is connected to the driving motor 131 and is rotatably connected in the stirring box 12 . The driving motor 131 is connected to one side outside the stirring box 12 .
[0030] Through the above design, the stirring roller 132 can turn the raw tea when it is rehydrated, thereby ensuring that the raw tea can be in contact with water more evenly when it is rehydrated.
[0031] Furthermore, the stirring roller 132 is provided with a brush 1321 arranged along the outer edge thereof.
[0032] The brush 1321 can prevent the raw tea from being damaged during stirring.
[0033] Preferably, the weighing mechanism 3 comprises a conveying unit 31 and a weighing unit 32 . The conveying unit 31 is located below the mixing box 12 , and the weighing unit 32 is located at the end of the conveying unit 31 in the conveying direction.
[0034] In this embodiment, after the raw tea is rehydrated, the staff puts the frame for collecting the raw tea on the conveying unit 31, and then opens the arc door 11 to collect the rehydrated raw tea. After collecting, the conveying unit 31 is started again to convey the frame of raw tea to the weighing unit 32 for weighing. After obtaining the data, the moisture content is calculated, and whether it needs to be rehydrated again is confirmed based on the moisture content.
[0035] More preferably, the conveying unit 31 is a conveying roller.
[0036] Through the above design, the conveying roller can effectively prevent moisture from remaining.
[0037] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
