Abstract
Description
Technical Field
[0001] This utility model relates to the field of matcha powder screening and impurity removal technology, and more specifically, to a matcha powder screening and impurity removal device. Background Technology
[0002] Currently, in the production and processing of matcha powder, screening and impurity removal is a core step in ensuring product quality, and the quality of this technology directly affects the final quality of the matcha powder. At present, existing technologies in the field of matcha powder screening and impurity removal face a series of problems that urgently need to be solved.
[0003] Some traditional screening and impurity removal devices have significant design flaws in the feeding stage. Their feeding methods are not scientifically sound and their structures are too simplistic, making it difficult to achieve uniform feeding of matcha powder. In actual production, due to uneven feeding, the matcha powder is unevenly distributed in the subsequent screening area, resulting in some areas of accumulated powder while others are sparse, severely impacting screening efficiency. This not only prolongs screening time and increases production costs but also easily leads to incomplete screening, preventing the effective removal of impurities and thus affecting the quality of the matcha powder.

[0006] In a preferred embodiment of this utility model, multiple sets of the mixing components are slidably connected to each other in a row, and their total length is the same as the distance between the two sides of the inner wall of the screening box.
[0007] In a preferred embodiment of this utility model, the two sides of the pouring pipe are inclined, and multiple guide plates are symmetrically fixed between the two sides of the inner wall of the pouring pipe. The top of the guide plates decreases sequentially from the outside to the center, and the pouring pipe is positioned directly above the mixing assembly.
[0008] In a preferred embodiment of this utility model, the feeding assembly includes a feeding pipe and a feeding hopper. The feeding pipe is fixedly installed at the top of the pouring pipe, and the feeding hopper is fixedly installed at the top of the feeding pipe. A second rotating shaft is rotatably installed between the two sides of the inner wall of the feeding pipe. Multiple diverting plates are fixedly installed on the second rotating shaft.

[0013] The beneficial effects of this utility model are:
[0014] Uniform feeding: The diverter plate on the second rotating shaft in the feeding assembly rotates under the drive of the drive assembly, which allows the matcha powder poured from the feeding hopper to enter the pouring pipe evenly. In conjunction with the guide plate that is inclined and has a gradually changing height at the top inside the pouring pipe, the matcha powder can be sprinkled more evenly on the mixing assembly, ensuring the stability and efficiency of subsequent processes.
[0015] Thorough mixing: When the first shaft rotates, the first mixing column drives the second mixing column to rotate in the opposite direction through the first gear and the internal gear.

[0016] Precise and efficient screening: The screening components employ a first vibrating screen and a second vibrating screen, with the mesh size of the first vibrating screen being larger than that of the second vibrating screen. The two screens are tilted in opposite directions and driven by a vibration motor. Matcha powder undergoes preliminary screening first through the first vibrating screen, where large particles of impurities are retained. Qualified matcha powder then falls into the second vibrating screen for secondary screening, which can accurately screen out impurities of different sizes, improving screening quality and efficiency.
[0017] Convenient discharge: The discharge port is set on one side of the screening box, and the bottom of the inner wall is inclined, which makes it easy for the qualified matcha powder to slide smoothly into the discharge port and be discharged, reducing residue and improving production convenience.

Detailed Implementation
[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0026] Please see Figures 1-4 This utility model provides a technical solution: a matcha powder screening and impurity removal device, including a screening box 110, a pouring pipe 120 fixedly installed at the top of the screening box 110, a guide component installed inside the pouring pipe 120, a feeding component fixedly installed at the top of the pouring pipe 120, a first rotating shaft 130 rotatably installed between the two sides of the inner wall of the screening box 110, and multiple sets of mixing components installed on the first rotating shaft 130. The mixing components include a first mixing column 131 and a second mixing column 132. The first mixing column 131 is fixed. The first rotating shaft 130 is mounted on the first rotating shaft 130 and one end is rotatably connected to the second mixing column 132. The second mixing column 132 is slidably mounted on the first mixing column 131. A circular groove is provided at one end of the first mixing column 131 near the second mixing column 132. A ring-shaped first gear 133 is fixedly mounted on the inner wall of the circular groove. An internal gear 134 that meshes with the first gear 133 is fixedly mounted at one end of the second mixing column 132. A drive assembly is mounted at one end of the first rotating shaft 130. A screening assembly is installed inside the screening box 110.
[0027] In some specific implementations, multiple sets of mixing components are slidably connected in a row, with their total length being the same as the distance between the two sides of the inner wall of the screening box 110. During the mixing process, this arrangement ensures that the matcha powder is dispersed and stirred throughout the entire screening box 110, avoiding any dead zones in the dispersion. This greatly improves the uniformity of the mixing and lays a solid foundation for subsequent screening to obtain matcha powder with uniform impurity distribution and consistent quality.
[0028] In some specific implementation schemes, the two sides of the pouring pipe 120 are inclined, and multiple guide plates 121 are symmetrically fixed between the two sides of the inner wall of the pouring pipe 120. The top of the guide plates 121 decreases sequentially from the outside to the center. The pouring pipe 120 is positioned directly above the mixing component. The inclined pouring pipe 120 and the specially designed guide plates 121 can guide the matcha powder entering from the feeding component to be evenly dispersed and accurately sprinkled onto the mixing component below, further enhancing the uniformity of feeding, reducing the accumulation and agglomeration of matcha powder during the pouring process, and ensuring the smooth progress of the mixing and screening processes.
[0029] Please see Figures 3-5 The feeding assembly includes a feeding pipe 140 and a feeding hopper 141. The feeding pipe 140 is fixedly installed at the top of the pouring pipe 120, and the feeding hopper 141 is fixedly installed at the top of the feeding pipe 140. A second rotating shaft 142 is rotatably installed between the two sides of the inner wall of the feeding pipe 140. Multiple diverting plates 143 are fixedly installed on the second rotating shaft 142. One end of the second rotating shaft 142 is connected to the drive assembly for transmission. The diverting plates 143 are slidably connected to the inner wall of the feeding pipe 140. The drive assembly includes a support box 150, a first motor 151, and a third rotating shaft 152. The support box 150 is fixedly installed on the side wall of the screening box 110. One side of the support box 150 is open. A third rotating shaft 152 is rotatably installed between the two sides of the inner wall of the support box 150. The first motor 151 is fixedly installed at the top of the third rotating shaft 152. A first bevel gear and a second bevel gear are fixedly installed on the third rotating shaft 152. A third bevel gear and a fourth bevel gear are fixedly installed at one end of the first rotating shaft 130 and the first bevel gear, respectively. The third bevel gear and the first bevel gear are meshed together, and the fourth bevel gear and the second bevel gear are meshed together. The screening assembly includes a first vibrating screen 160 and a second vibrating screen 161. Partitions 162 are symmetrically fixedly installed on the inner wall of the screening box 110. The first vibrating screen 160 and the second vibrating screen 161 are respectively installed on one side of the two partitions 162 that are relatively close to each other. Vibration motors are fixedly installed at the bottom of the first vibrating screen 160 and the second vibrating screen 161. The first vibrating screen 160 and the second vibrating screen 161 are arranged at opposite inclinations. The first vibrating screen 160 is above the second vibrating screen 161. The bottom ends of the first vibrating screen 160 and the second vibrating screen 161 pass through the adjacent partitions 162. The partitions 162 are provided with strip holes that match the first vibrating screen 160 and the second vibrating screen 161.
[0030] In some specific implementations, the mesh size of the first vibrating screen 160 is larger than that of the second vibrating screen 161. This differential design enables graded screening. The matcha powder first passes through the first vibrating screen 160, where larger particles of impurities are intercepted. The pre-screened matcha powder then enters the second vibrating screen 161 for more refined screening. Graded screening can accurately separate impurities of different particle sizes, improving screening precision, meeting the stringent requirements for matcha powder quality, and ensuring that the final matcha powder has a more uniform and pure particle size.
[0031] In some specific implementation schemes, a discharge port is provided on one side of the screening box 110, and the bottom of the inner wall of the screening box 110 is inclined. The inclined bottom of the box allows qualified matcha powder to slide smoothly down to the discharge port by its own gravity, reducing the workload of manual cleaning and collection, while avoiding the residue of matcha powder at the bottom of the box, improving production efficiency, ensuring the cleanliness and purity of the screened product, and reducing the risk of secondary pollution.
[0032] Working principle: During use, matcha powder is poured into the feed hopper 141. The first motor 151 is started, driving the third rotating shaft 152 to rotate. The rotation of the third rotating shaft 152 drives the first and second bevel gears to rotate, which in turn drives the second rotating shaft 142 and the first rotating shaft 130 to rotate synchronously. The rotation of the first rotating shaft 130 drives the distribution plate 143 to rotate, ensuring even feeding. After entering the pouring pipe 120, the matcha powder is evenly distributed onto the mixing assembly by the guide plate 121. The first rotating shaft 13... The rotation of the first mixing column 131 drives the first mixing column 131 to rotate. The rotation of the first mixing column 131 drives the second mixing column 132 to rotate in the opposite direction through the cooperation of the first gear 133 and the internal gear 134, thereby evenly sprinkling the matcha powder onto the first vibrating screen 160. The vibration motor is started to drive the first vibrating screen 160 and the second vibrating screen 161 to vibrate, and the qualified matcha powder is screened onto the second vibrating screen 161 for secondary screening. The qualified matcha powder slides down to the bottom of the screening box 110, and the unqualified matcha powder slides down to the two sides of the partition 162 respectively.
[0033] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
