Description

Technical Field

[0001] This utility model relates to the field of tea processing technology, and in particular to a tea processing device with a sieving function. Background Technology

[0002] Tea grinding and sieving is a crucial process in tea refining. Its core purpose is to optimize tea quality, improve processing efficiency, and meet diverse product demands through physical means. Firstly, grinding breaks down the original fibrous structure of tea leaves, increasing surface area and promoting the efficient release of internal substances. Especially in the production of instant tea powder, tea concentrate, or food additives, grinding significantly improves extraction rates and product yields. However, different tea products require different particle sizes; therefore, sieving is necessary after grinding to maintain uniform particle diameter and improve product quality.

[0003] A search revealed a Chinese patent publication number CN214554173U, which discloses a tea processing pulverizer, including a base. Support legs are symmetrically fixedly connected to the upper middle part of the base. A pulverizing box is fixedly connected to the upper end of the support legs. A pulverizing roller is arranged in the middle of the pulverizing box. Pulverizing blades are fixedly connected in an array on the upper surface of the pulverizing roller. A driven wheel is fixedly connected to one side of the pulverizing roller and is located outside the pulverizing box.

[0004] To address the issue that the aforementioned technologies lack filtration components and cannot cool the pulverizing components, which can easily lead to the tea leaves overheating during pulverization, altering the flavor and affecting quality, a tea processing device with a sieving function is proposed.

[0028] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this invention. Therefore, the drawings and description are considered exemplary in nature and not restrictive.

[0029] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0030] Example 1:

[0031] like Figure 1-6 As shown, a tea processing device with a sieving function includes a tank 1 with a feeding trough 2 on the top. Tea leaves can be poured into the tank 1 from the feeding trough 2 for crushing. Filter plates 17 are fixedly connected to both sides of the lower part of the tank 1. Guide ramps 16 are fixedly connected to the lower part of the filter plates 17. Multiple air jets 24 are fixedly connected to the upper part of the guide ramps 16. The air inlet ends of the multiple air jets 24 are fixedly connected to backwash pumps 15 through pipes. A crushing component is fixedly connected inside the tank 1. Multiple ventilation slots 13 are opened at the connection between the tank 1 and the crushing component. Multiple heat dissipation fins 21 are fixedly installed inside the ventilation slots 13.

[0032] After the tea leaves are crushed, they are discharged from the bottom and fall onto the inclined filter plates 17 on both sides. Then, by suction airflow, the tea powder is drawn through the filter plates 17. At this time, the powder that meets the screening standard is collected by the filter plates 17, while the large particles that do not meet the standard fall onto the guide ramp 16 below.

[0033] However, during this process, some small particles of powder fall to the bottom before passing through the filter plate 17. At this time, the backwash pump 15 is started and multiple jet nozzles 24 are used to spray air from below to re-spray the powder that has fallen to the bottom, so that the powder at the bottom can be filtered again.

[0034] Meanwhile, the preferred backwash pump 15 can be connected to an external air conditioning unit, so that the gas blown in can be low-temperature gas. This gas will cool the tea leaves, and some of this low-temperature gas will enter the ventilation slot 13 upwards, which can cool the pulverizing component that can be connected to the heat dissipation fins 21. This will reduce the temperature of the blades during pulverization and further prevent the tea powder from heating up and causing changes in flavor.

[0035] In this embodiment, the crushing assembly includes an adjusting push rod 3, a crushing motor 4, a crushing head 18, and a crushing blade ring 19. One side of the crushing blade ring 19 is fixedly connected to multiple heat dissipation fins 21 and the inside of the tank 1. The adjusting push rod 3 is fixedly connected to the top of the tank 1. The movable end of the adjusting push rod 3 is fixedly connected to the crushing motor 4. The power output end of the crushing motor 4 is fixedly connected to the top of the crushing head 18.

[0036] The crushing blade ring 19 is installed inside the tank body 1 and can be cooled by the ventilation slot 13 and heat dissipation fins 21. The rotating crushing head 18 can crush the tea leaves, and the adjusting push rod 3 is a hydraulic type, which can adjust the distance between the crushing head 18 and the crushing blade ring 19 to adjust the size of the tea powder.

[0037] In this embodiment, suction hoods 9 are fixedly connected to both sides of the filter plate 17, and an electric switch 12 is fixedly connected to the air outlet of the suction hood 9; the other end of the electric switch 12 is fixedly connected to a sieving pump 10 through a pipe, and a storage box 11 is fixedly connected to the air outlet of the sieving pump 10.

[0038] The sieving pump 10 can draw in air, carry the powder through the filter plate 17, and blow it into the storage box 11 for storage.

[0039] In this embodiment, a surrounding plate 25 is fixedly connected to the top of the guide ramp 16 and both sides of the filter plate 17. The top of the guide ramp 16 is inclined. An electric baffle 14 is fixedly connected to one end of one side of the surrounding plate 25, and a feed pipe 8 is fixedly connected to one end of the surrounding plate 25. A temporary storage tank 7 is fixedly connected to the other end of the feed pipe 8.

[0040] The inclined guide ramp 16 at the top can guide the large powder particles that accumulate at the top to accumulate at the bottom. Every once in a while, the electric baffle 14 is opened by the motor on one side, allowing the accumulated large powder particles to flow into the temporary storage tank 7. These powder particles can be re-crushed or collected for other uses.

[0041] In this embodiment: After the tea leaves are crushed, they are discharged from below and fall onto the inclined filter plates 17 on both sides. Then, by suction airflow, the tea powder is drawn through the filter plates 17. At this time, the powder that meets the screening standard is collected by the filter plates 17, while the large particles that do not meet the standard fall onto the guide ramp 16 below.

[0042] However, during this process, some small particles of powder fall to the bottom before passing through the filter plate 17. At this time, the backwash pump 15 is started and multiple jet nozzles 24 are used to spray air from below to re-spray the powder that has fallen to the bottom, so that the powder at the bottom can be filtered again.

[0043] Meanwhile, the preferred backwash pump 15 can be connected to an external air conditioning unit, so that the gas blown in can be low-temperature gas. This gas will cool the tea leaves, and some of this low-temperature gas will enter the ventilation slot 13 upwards, which can cool the pulverizing component that can be connected to the heat dissipation fin 21. This can reduce the temperature of the blades during pulverization and further prevent the tea powder from heating up and causing changes in flavor.

[0044] The crushing blade ring 19 is installed inside the tank body 1 and can be cooled by the ventilation slot 13 and heat dissipation fins 21. The rotating crushing blade head 18 can crush the tea leaves, and the adjusting push rod 3 is a hydraulic type, which can adjust the distance between the crushing blade head 18 and the crushing blade ring 19 to adjust the size of the tea powder.

[0045] The sieving pump 10 can draw in air to carry the powder through the filter plate 17 and blow it into the storage tank 11 for storage. The inclined guide ramp 16 at the top can guide the large powder particles that accumulate at the top to accumulate at the bottom. Every once in a while, the electric baffle 14 is rotated and opened by the motor on one side, allowing the accumulated large powder particles to flow into the temporary storage tank 7. These powder particles can be re-crushed or collected for other uses.

[0046] Example 2:

[0047] A tea processing device with a sieving function is provided in this embodiment, which is improved upon embodiment 1 as follows: Figure 1-6 As shown,

[0048] In this embodiment, a recovery pump 5 is fixedly connected to the top of the tank 1. The air inlet of the recovery pump 5 is fixedly connected to the inside of the temporary storage tank 7 through a pipe, and a recovery pipe 6 is fixedly connected to the air outlet of the recovery pump 5.

[0049] The recovery pump 5 is an air pump that can suck up large tea powder particles from the temporary storage tank 7 and spray them back into the feed trough 2 through the recovery pipe 6 for secondary crushing.

[0050] In this embodiment, a filter screen 20 and a discharge pipe 22 are fixedly connected to the bottom of the tank body 1, and a discharge inclined pipe 23 is fixedly connected to the lower end of the discharge pipe 22.

[0051] The filter screen 20 can reduce the dust carried in the airflow sprayed from above. The discharge pipe 22, together with the flat discharge inclined pipe 23, allows the powder to fall evenly onto the filter plates 17 on both sides. The outlet of the discharge inclined pipe 23 has a slanted cut, which can prevent the downward blowing airflow from the discharge pipe 22 from blowing into the crushing component and affecting the crushing.

[0052] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
