Description

Technical Field

[0001] This utility model relates to the field of food processing equipment technology, specifically a novel cleaning device for milk tea powder production that facilitates the removal of impurities. Background Technology

[0002] With the rapid development of the milk tea industry, consumers' demands for the quality of milk tea powder are increasing. Among these demands, "impurity content" is one of the core indicators affecting the taste, safety, and market acceptance of milk tea powder. During the procurement, transportation, and storage of raw materials for milk tea powder (such as milk powder, non-dairy creamer, tea powder, and white sugar), large particulate impurities (such as raw material clumping, packaging bag fibers, and stones from transportation) can easily be introduced. During the production and processing stages (such as mixing and grinding), small particulate impurities (such as fine dust from equipment wear and tear, and tiny grains of sand from the environment) may be introduced. If these impurities are not thoroughly removed, they can not only cause sedimentation and a rough taste after the milk tea is prepared, but may also scratch the digestive tract and trigger allergies, violating the "National Food Safety Standard for Solid Beverages" (GB / T29602) which stipulates that "food must not contain foreign matter." Existing screening equipment often uses a fixed connection between the screen frame and the support structure, which is prone to displacement during vibration, leading to a decrease in screening efficiency. Furthermore, the screen frame needs to be disassembled for cleaning after the filter screen becomes clogged, interrupting the production process. Secondly, the lack of a directional material guiding structure means that the trapped impurities tend to accumulate inside the screen frame, requiring frequent manual cleaning and increasing the workload. Against this backdrop, there is an urgent need to develop a milk tea powder impurity removal device that can achieve "graded impurity removal, automatic feeding, stable vibration, and easy maintenance" to solve the problems of incomplete impurity removal, low efficiency, and cumbersome operation of existing equipment, and meet the needs of large-scale and refined production of milk tea powder.

[0003] Therefore, those skilled in the art have provided a novel cleaning device for milk tea powder production that facilitates the removal of impurities, in order to solve the problems mentioned in the background art. Utility Model Content

[0004] The purpose of this invention is to provide a novel cleaning device for milk tea powder production that facilitates the removal of impurities, thereby solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A novel impurity removal device for milk tea powder production includes a dust collection box, which is a cylindrical structure with an open top. Above the open top, a coarse sieve frame and a fine sieve frame are arranged sequentially from top to bottom. Both the coarse and fine sieve frames are circular structures adapted to the diameter of the dust collection box, and both have open tops. A vibration motor is fixedly installed on the outer wall of both the coarse and fine sieve frames. A coarse filter screen is fixedly installed at the bottom of the coarse sieve frame, and a fine filter screen is fixedly installed at the bottom of the fine sieve frame. The pore size of the coarse filter screen is larger than the particle size of the milk tea powder, and the pore size of the fine filter screen is smaller than the particle size of the milk tea powder.

[0006] As a further embodiment of this utility model: the dust collection box is provided with four supporting ear blocks at equal angles along the edge of the opening end. The supporting ear blocks are circular in structure, and each of them is fixedly connected to a guide post at its center.

[0007] As a further improvement of this utility model: the coarse screen frame and the fine screen frame are provided with four sliding lugs at equal angles along the edge of the opening end, and the center of the sliding lugs is provided with a through hole corresponding to the guide post.

[0008] As a further improvement of this utility model: a guide sleeve is embedded in the through hole; the coarse screen frame and the fine screen frame are slidably connected to the guide post through sliding lugs.

[0009] As a further improvement of this utility model: a supporting spring is sleeved on the guide post between the coarse screen frame and the fine screen frame, and a supporting spring is also sleeved on the guide post between the fine screen frame and the dust collection box.

[0010] As a further embodiment of this utility model: a first discharge port is provided on one side wall of the coarse screen frame, and a feed port is provided on the side wall of the dust collection box corresponding to the first discharge port. A slide is fixedly connected between the first discharge port and the feed port.

[0011] As a further improvement of this utility model: a second discharge port is provided on one side wall of the fine screen frame, and a discharge pipe is fixedly connected to the outside of the second discharge port.

[0012] As a further improvement of this utility model: a spiral guide bar is provided in both the coarse screen frame and the fine screen frame, and the ends of the spiral guide bar are respectively connected to the first discharge port and the second discharge port.

[0013] Compared with existing technologies, the advantages of this utility model are as follows: First, through the double-layer screening structure of "coarse screen frame + fine screen frame", the coarse and fine filters can simultaneously separate "large impurities larger than powder particles" and "small impurities smaller than powder particles" in milk tea powder. Compared with traditional single screening devices, it achieves graded removal of impurities, significantly improves the purity of milk tea powder, and effectively avoids impurities affecting product taste and food safety. Second, the spiral guide strips in the coarse and fine screen frames can guide the trapped impurities and purified milk tea powder to move directionally to the corresponding discharge ports. Combined with the design of the inclined slide and discharge pipe, it realizes the streamlined operation of "impurities automatically collected to the dust collection box and clean milk tea powder smoothly discharged", eliminating the need for frequent manual cleaning of the screen frames. The centralized collection of impurities in the dust collection box reduces the frequency of cleaning and the difficulty of operation, improving production continuity. In addition, the overall structure of the device is compact, and the standardized design of components such as the supporting ear block and guide column facilitates assembly and maintenance. It has a wide range of applications and can effectively adapt to small and medium-sized milk tea powder production scenarios, reducing production and operating costs while ensuring product quality.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Reference Figures 1-5 This embodiment provides a novel cleaning device for milk tea powder production that facilitates the removal of impurities, including a dust collection box 1, a coarse sieve frame 6, and a fine sieve frame 7.

[0022] The dust collection box 1 is a cylindrical structure with an open end at the top for collecting various impurities generated during filtration. The dust collection box 1 has four supporting lugs 2 spaced at 90° intervals along the edge of the open end. Each supporting lug 2 is circular, and a guide post 3 is vertically fixed to its center.

[0023] Both the coarse sieve frame 6 and the fine sieve frame 7 are circular structures adapted to the diameter of the dust collection box 1. The upper end of both is open, and the inner wall is polished with a surface roughness Ra=0.8μm to avoid the accumulation of milk tea powder residue.

[0024] The coarse screen frame 3 and the fine screen frame 7 are provided with four sliding lugs 8 at 90° intervals along the edge of the opening end. The center of the sliding lug 8 is provided with a through hole 9 corresponding to the guide post 3. A guide sleeve is embedded in the through hole 9. The inner diameter of the guide sleeve is adapted to the outer diameter of the guide post 3, so that the coarse screen frame 6 and the fine screen frame 7 can slide smoothly along the guide post 3 through the sliding lugs 8.

[0025] A support spring 5 is fitted on the guide post 3 between the coarse screen frame 6 and the fine screen frame 7. A support spring 5 is also fitted on the guide post 3 between the fine screen frame 7 and the dust collection box 1. The support spring 5 is used to buffer vibration and support the weight of the screen frame.

[0026] Vibration motors 15 are bolted to the outer walls of both the coarse screen frame 6 and the fine screen frame 7 to provide power for vibrating screening.

[0027] A coarse filter screen 16 with a pore size larger than that of milk tea powder is fixedly installed at the bottom of the coarse sieve frame 6. It is used to filter impurities larger than that of milk tea powder. A fine filter screen 17 with a pore size smaller than that of milk tea powder is fixedly installed at the bottom of the fine sieve frame 7. It is used to filter impurities smaller than that of milk tea powder.

[0028] A first discharge port 11 is provided on one side wall of the coarse screen frame 6, and a feed port 4 is provided on the side wall of the dust collection box 1 corresponding to the first discharge port 11, with the size matching the first discharge port 11; a slide 13 is fixedly connected between the first discharge port 11 and the feed port 4, and the slide 13 is inclined downward with an angle of 30° with the horizontal plane, so that large particles of impurities can slide into the dust collection box 1.

[0029] A second discharge port 12 is provided on one side wall of the fine sieve frame 7, and a discharge pipe 14 is fixedly connected to its outer side for discharging the purified milk tea powder.

[0030] A spiral guide bar 10 is welded inside both the coarse sieve frame 6 and the fine sieve frame 7. The ends of the spiral guide bar 10 are smoothly connected to the first discharge port 11 and the second discharge port 12, respectively, to guide impurities and purified milk tea powder to move towards the discharge port.

[0031] When using it, first start the vibration motor 15 on the coarse sieve frame 6 and the fine sieve frame 7, so that the two sieve frames will generate high-frequency vibration along the guide post 3 under the action of the support spring 5; pour the milk tea powder to be processed evenly into the middle opening of the coarse sieve frame 6.

[0032] Under the vibration of the coarse screen frame 6: Impurities larger than the milk tea powder particles (such as clumps, coarse fibers, pebbles, etc.) are intercepted by the coarse filter screen 16 and move towards the first discharge port 11 under the guidance of the spiral guide bar 10. They then slide into the dust collection box 1 through the slide 13 and the feed port 4 for collection. Milk tea powder and impurities smaller than its particle size fall through the coarse filter 16 into the fine sieve frame 7 below.

[0033] Under the vibration of the fine screen frame 7: Impurities smaller than the milk tea powder particles (such as fine dust, tiny sand, etc.) fall directly into the dust collection box 1 through the fine filter 17 and are collected. The purified milk tea powder is trapped by the fine filter 17 and moves towards the second discharge port 12 under the guidance of the spiral guide bar 10. It is then discharged into the collection box below through the discharge pipe 14.

[0034] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0035] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
