[0002] Ripe tea is made from Yunnan large-leaf sun-dried green tea leaves through fermentation and other processes. Ripe tea has a brown-red color, a pure and mellow taste, and a unique aged aroma. The processing steps of ripe tea mainly include picking, withering, rolling, fermentation, drying, storage and aging.

[0003] The processing of cooked tea is a delicate and complex process that requires multiple steps. Each link requires strict control to ensure the quality and taste of the tea. The fermentation process is the key link in the production of cooked tea. Through fermentation, the caffeine and amino acids in the tea will react to produce a special flavor and aroma.

[0004] However, in the prior art, when the residue is processed during the processing of cooked tea, the residue filtered on the filter plate or filter screen will cause clogging of the filter screen or filter plate, resulting in a reduction in the subsequent filtration performance of the filter screen or filter plate, and it is difficult to clean the residue that clogs the filter screen and filter plate. Utility Model Content

[0005] The technical problem to be solved by the present invention is that when the filter residue is processed during the processing of cooked tea, the residue filtered on the filter plate or filter screen will cause clogging of the filter screen or filter plate, resulting in a reduction in the subsequent filtration performance of the filter screen or filter plate, and it is difficult to clean the residue that clogs the filter screen or filter plate.

[0006] In order to solve the above technical problems, the technical solution of the utility model is:

[0007] A residue filtering device for processing cooked tea comprises four supporting columns, the top ends of the four supporting columns are fixed with drainage plates, one end of the drainage plates is provided with a discharge port, four electric telescopic rods are installed below the drainage plates, the movable ends of the electric telescopic rods pass through the drainage plates, and the movable ends of the electric telescopic rods are fixed with filter plates, a plurality of filter holes are distributed on the surface of the filter plates in a rectangular array, a plurality of fixed rods are fixed to the rectangular array on the surface of the drainage plates, the fixed rods correspond to the filter holes one by one and their axes coincide, a dredging rod is slidably installed on the outer sides of the top ends of the fixed rods, and a buffer spring is fixed between the dredging rod and the fixed rod.

DETAILED DESCRIPTION

[0020] The following further describes specific embodiments of the present invention in conjunction with the accompanying drawings. It should be noted that the descriptions of these embodiments are intended to aid understanding of the present invention and do not constitute limitations on the present invention. Furthermore, the technical features involved in the various embodiments of the present invention described below may be combined with one another as long as they do not conflict with one another.

[0021] like Figure 1 As shown, a guide plate 2 is fixed to the top of the four support columns 1, and a discharge port 3 is provided at one end of the guide plate 2. Four electric telescopic rods 4 are installed below the guide plate 2. The movable end of the electric telescopic rod 4 passes through the guide plate 2, and the movable end of the electric telescopic rod 4 is fixed to the filter plate 5. A plurality of penetrating filter holes 7 are distributed in a rectangular array on the surface of the filter plate 5. A plurality of fixed rods 13 are fixed to the rectangular array on the surface of the guide plate 2. The fixed rods 13 correspond to the positions of the filter holes 7 one by one and the axes coincide with each other. A dredging rod 14 is slidably installed on the outer side of the top of the fixed rod 13, and a buffer spring 15 is fixed between the dredging rod 14 and the fixed rod 13. The lifting and lowering of the filter plate 5 is controlled by the electric telescopic rod 4. During the descending process of the filter plate 5, the dredging rod 14 is used to penetrate the filter hole 7 to dredge the residue blocked in the filter hole 7, thereby ensuring that the filtering performance of the filter plate 5 will not decrease.

[0022] like Figure 1 and Figure 2 As shown, in this embodiment, a filter residue collection plate 6 is slidably installed on the inner side of the filter plate 5, a movable screw 8 is installed through one end of the filter residue collection plate 6, and a guide rod 10 is installed through the other end of the filter residue collection plate 6. Support blocks 9 are installed on the outer sides of both end portions of the movable screw 8 and the guide rod 10. The support blocks 9 are fixed to the filter plate 5, and the ends of the movable screw 8 and the guide rod 10 are connected to the support blocks 9 through roller bearings. The ends of the filter residue collection plate 6 are supported by the guide rod 10 to ensure that the filter residue collection plate 6 can only move linearly along the axial direction of the guide rod 10, thereby preventing the filter residue collection plate 6 from rotating simultaneously with the movable screw 8.

[0023] The movable screw rod 8 and the filter residue collection plate 6 are transmitted through a thread. One end of the movable screw rod 8 is connected to the driving motor 11 through a fixing pin. A support plate 12 is fixed below the driving motor 11. One end of the support plate 12 is fixed to one end of the filter plate 5. The movable screw rod 8 is driven to rotate by the driving motor 11, so that the movable screw rod 8 is transmitted through the thread with the filter residue collection plate 6, so that the filter residue collection plate 6 moves along the axis of the movable screw rod 8, so that the filter residue collection plate 6 collects the residue ejected from the filter hole 7 in a centralized manner.

[0024] As the preferred technical solution of this embodiment, Figure 1 、 Figure 3 and Figure 4 As shown, the outer diameter of the dredging rod 14 is the same as the inner diameter of the filter hole 7, and the top of the dredging rod 14 is a spherical surface. The residue in the filter hole 7 is completely removed by the dredging rod 14, and during the movement of the filter residue collection plate 6, the dredging rod 14 can be squeezed into the filter hole 7 by the moving filter residue collection plate 6 without affecting the normal movement of the filter residue collection plate 6.

[0025] Two guide grooves 18 are provided inside the dredging rod 14, and two mounting slots 16 are provided on the outer side of the top end of the fixing rod 13. The inner side of the mounting slot 16 is clamped with a rubber limit block 17. The rubber limit block 17 is made of rubber and is partially clamped on the inner side of the guide groove 18. The rubber limit block 17 is used to limit the position of the dredging rod 14 to prevent the dredging rod 14 from falling off from the outer side of the top end of the fixing rod 13 without affecting the downward movement of the dredging rod 14.

[0026] Working principle: Place the device on the ground at an angle and ensure that the end of the drainage plate 2 with the discharge port 3 is lower than the other end of the drainage plate 2. Then pour the cooked tea to be filtered onto the surface of the filter plate 5. The liquid in the cooked tea passes through the filter holes 7 and reaches the surface of the support column 1. After the liquid is filtered, it leaves the support column 1 from the discharge port 3, and the filtered residue is intercepted on the surface of the filter plate 5. When the filter hole 7 is blocked by the residue, it is only necessary to power on the electric telescopic rod 4 and drive the filter plate 5 to move downward. When the filter plate 5 moves downward, the dredging rod 14 remains stationary due to the restriction of the buffer spring 15. The descending filter plate 5 makes the dredging rod 1 4 passes through the filter holes 7, pushing the residue in the filter holes 7 out of the filter holes 7 until the top spherical edge of the dredging rod 14 is flush with the surface of the filter plate 5. At this time, the driving motor 11 is powered on and starts to drive the movable screw 8 to rotate. The movable screw 8 causes the filter residue collection plate 6 to move linearly along the axis of the guide rod 10 through thread transmission. The filter residue collection plate 6 moves from one end of the filter plate 5 to the other end, and the residue on the surface of the filter plate 5 is concentrated and gathered, shortening the cleaning time of the filter plate 5, improving the dredging and cleaning efficiency of the filter plate 5, and preventing the filter holes 7 from being blocked, thereby ensuring that the filtering performance of the filter plate 5 will not be reduced.

[0027] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. It is apparent to those skilled in the art that various changes, modifications, substitutions, and variations to these embodiments may be made without departing from the principles and spirit of the present invention, and these changes and modifications still fall within the scope of protection of the present invention.
