Abstract
Description
Technical Field
[0001] This utility model belongs to the field of preparation device technology, specifically relating to a hemp seed tea preparation device. Background Technology
[0002] Hemp seeds, also known as flax seeds, are the dried, ripe fruit of the hemp plant (Cannabis sativa), a member of the mulberry family. Hemp seed tea is a beverage made primarily from hemp seeds. Hemp seeds are rich in oils, proteins, minerals, and various vitamins, offering numerous health benefits.
[0003] In preparing and brewing hemp seed tea, to enhance the release of hemp seed components and improve the efficacy of the tea, the hemp seeds need to be crushed to allow water to fully contact the inside of the hemp seeds and release the effective components into the tea. However, in existing technologies, hemp seeds are generally crushed by pounding with a pestle and mortar. This method is time-consuming and the crushing effect is not good enough, affecting the quality of the crushed hemp seeds. At the same time, it is difficult to maintain a constant temperature inside the brewing container during the tea brewing process, which can easily cause the water to overheat and boil, resulting in the destruction of the effective components in the hemp seeds. Utility Model Content
[0004] To address the above problems, the purpose of this utility model is to provide a sesame seed tea preparation device that enables sesame seeds to be uniformly crushed, controls the maximum particle size of the crushed sesame seeds, improves the consistency of the tea soup's taste and the release of sesame seed components during tea brewing, and maintains the water temperature inside the inner pot at a suitable temperature, avoiding overheating and boiling. This ensures that bacteria are killed while preventing the effective components in the sesame seeds from being destroyed by overheated water.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a sesame seed tea preparation device, comprising a conical grinding chamber, a first conveying pipe connected to the bottom side of the conical grinding chamber, a motor installed at the bottom of the conical grinding chamber, the output end of the motor connected to a rotating shaft, a grinding disc installed at the top of the rotating shaft, a sesame seed storage chamber at the bottom of the first conveying pipe, and multiple sets of ingredient storage chambers arranged side by side next to the sesame seed storage chamber. Each of the sesame seed storage chamber and the ingredient storage chambers is equipped with an electrically controlled butterfly valve at its bottom, and the bottom of the electrically controlled butterfly valve is connected to a multi-port pipe. The bottom of the multi-port pipe is fixed to the metering device, one end of the metering device is connected to the second conveying pipe, the bottom of the second conveying pipe is connected to the cooking tank, the cooking tank includes an inner liner, a phase change material layer is provided on the outside of the inner liner, an outer liner is provided on the outside of the phase change material layer, the top cover of the inner liner is connected to a condenser pipe, the other end of the condenser pipe is fixedly connected to one side of the inner liner, a valve is connected to the bottom of the inner liner, a discharge pipe is connected to the bottom of the valve, a filter chamber is provided in the middle section of the discharge pipe, and multiple sets of electric heating plates are provided at the bottom of the inner liner.
[0006] The beneficial effects of this invention are as follows: When using this device, the hemp kernels to be crushed are put into the conical crushing chamber. The motor drives the rotating shaft and the crushing blades to rotate rapidly. While crushing the hemp kernels, the hemp kernels are driven to move upward in a spiral motion along the direction of the spiral guide plate and against the inner wall of the conical crushing chamber under the action of centrifugal force. This allows the hemp kernels to further collide with the fixed crushing blades. The hemp kernels are uniformly crushed by the cooperation of the first crushing blade and the fixed crushing blade. The hemp kernel fragments that meet the standard particle size pass through the space between the crushing blades and the conical crushing chamber. The sesame seeds fall through the gaps to the bottom of the conical grinding chamber and are then conveyed into the hemp seed storage chamber through the first conveying pipe. The hemp seed fragments that do not meet the grinding standard are conveyed upwards again under the centrifugal force of the grinding disc and are circulated and crushed by the fixed crushing blades until the particle size is large enough to pass through the gap between the grinding disc and the conical grinding chamber. Then they fall to the bottom of the conical grinding chamber. Through the above settings, the hemp seeds can be evenly ground and the maximum particle size of the ground hemp seeds can be controlled, which improves the consistency of the tea soup taste and the ability of the hemp seed components to be released when brewing tea.
[0007] Before brewing the tea, open the electrically controlled butterfly valves at the bottom of the hemp seed storage bin and the ingredient storage bin. This allows the materials in the hemp seed storage bin and the ingredient storage bin to enter the receiving bin inside the metering device under gravity through the multi-port pipe. Note that the amount of material added to the receiving bin should be controlled according to the material ratio. By controlling the opening sequence of the electrically controlled butterfly valves, the materials are controlled to be discharged into the receiving bin in order of type. The weight sensor can weigh the materials entering the receiving bin and display the weighing data on the display screen of the equipment control panel. By using the change in the weighing data of the weight sensor after each type of material enters the receiving bin, the timing of closing the electrically controlled butterfly valve is determined to meet the requirements of the ratio accuracy.
[0008] After filling with water, seal the top of the water inlet pipe with the sealing cap. This allows the electric heating plate to heat the water inside the inner tank, starting the tea brewing process. The phase change material layer uses paraffin wax. As the water temperature rises, the phase change material layer absorbs heat conducted to the inner tank's sidewall. Before the inner tank surface temperature reaches the melting point of 85 degrees Celsius, the phase change material layer remains solid, absorbing heat to slow the rate of temperature rise inside the inner tank, improving heating uniformity and preventing localized overheating. When the inner tank surface temperature reaches the melting point of the phase change material layer, it enters the phase change stage and begins to melt, absorbing a large amount of latent heat to offset the heat input from the electric heating plate. During the melting process, the temperature of the phase change material layer is maintained at 85 degrees Celsius, ensuring a stable and synchronous water temperature inside the pipe. If overheating causes the inner tank temperature to rise further, the phase change material layer completely liquefies and stops absorbing heat. The heat is then dissipated through the outer tank. As a "thermal buffer pool," it limits temperature fluctuations to within ±2℃. Steam generated during tea brewing enters the condenser for condensation. The heat sink effectively improves condensation efficiency. Since the inner pot is sealed from the outside during brewing, the condenser collects and condenses the steam, preventing excessive evaporation of water and reducing tea loss. Timely condensation also prevents increased internal pressure due to tea vaporization, balancing the pressure and preventing explosions caused by excessive steam. The condensed water droplets flow back into the tea, working with the phase change material layer to balance the internal temperature. Through the combination of the phase change material layer and the condenser, the water temperature inside the inner pot is maintained at a suitable level, preventing overheating and boiling. This ensures the killing of bacteria while preventing the destruction of the active ingredients in the hemp seed due to overheating.
[0009] As a further improvement to the above technical solution: the conical crushing chamber is equipped with a spiral guide plate inside.
[0010] The beneficial effect of this improvement is that the spiral guide plate is used to guide the flow direction of hemp seeds as they rise through centrifugal force.
[0011] As a further improvement to the above technical solution: the top of the crushing disc is provided with a plurality of first crushing blades arranged in a ring, and the interior of the conical crushing chamber is provided with a multi-layered ring-arranged fixed crushing blade.

[0014] The beneficial effects of this improvement are as follows: the rotation direction of the first crushing blade is opposite to that of the fixed crushing blade, and the hemp kernels that are rotated and slid upward by the first crushing blade can directly collide with the blade of the fixed crushing blade for crushing. The setting of the serrations improves the crushing effect on the hemp kernels.
[0015] To ensure a precise ratio between hemp seeds and other ingredients:
[0016] As a further improvement to the above technical solution: the quantitative device is equipped with a weight sensor inside, the weight sensor is equipped with a support base on top, the support base is equipped with a receiving chamber on top, the receiving chamber is connected to an electric slide valve on the side, and one end of the electric slide valve is connected to a second delivery pipe.
[0017] The beneficial effects of this improvement are as follows: Before brewing tea, the electrically controlled butterfly valves at the bottom of the hemp seed storage bin and the ingredient storage bin are opened, allowing the materials in the hemp seed storage bin and the ingredient storage bin to enter the receiving bin inside the metering device under the action of gravity through the multi-port pipe. Note that the amount of material added to the receiving bin should be controlled according to the material ratio. By controlling the opening sequence of the electrically controlled butterfly valves, the materials are controlled to be discharged into the receiving bin in order of type. The weight sensor can weigh the materials entering the receiving bin and display the weighing data on the display screen of the equipment control panel. By using the change of the weighing data of the weight sensor after each type of material enters the receiving bin, the timing of closing the electrically controlled butterfly valve is determined to meet the requirements of the ratio accuracy.
[0018] To prevent moisture evaporation:
[0019] As a further improvement to the above technical solution: the top cover of the inner liner is connected to a water injection pipe, and the top of the water injection pipe is threaded with a sealing cap.
[0020] The beneficial effect of this improvement is that after filling the inner tank with water, the water filling pipe is sealed with a sealing cap to prevent water evaporation.

[0023] The beneficial effects of this improvement are: when the fully brewed tea soup is discharged, the brewed material particles are intercepted by the filter screen and remain in the filter chamber. The material residue can be cleaned by removing the filter screen fixing plate.
[0024] To facilitate filling of ingredients into the ingredient storage compartment:

Detailed Implementation
[0037] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of the present invention in any way.
[0038] like Figure 1-5 As shown, a sesame seed tea preparation device includes a conical grinding chamber 1. A first conveying pipe 3 is connected to the bottom side of the conical grinding chamber 1. A motor 4 is installed at the bottom of the conical grinding chamber 1, and the output end of the motor 4 is connected to a rotating shaft 5. A grinding disc 6 is installed at the top of the rotating shaft 5. A sesame seed storage chamber 10 is provided at the bottom of the first conveying pipe 3. Multiple sets of ingredient storage chambers 11 are arranged side by side next to the sesame seed storage chamber 10. An electrically controlled butterfly valve 12 is provided at the bottom of both the sesame seed storage chamber 10 and the ingredient storage chambers 11. The bottom of the electrically controlled butterfly valve 12 is connected to a multi-port pipe 13. The bottom of the multi-port pipe 13 is fixed to a metering device 14. The metering device 14 is connected at one end to the second conveying pipe 19, and the bottom of the second conveying pipe 19 is connected to the cooking tank 20. The cooking tank 20 includes an inner liner 21, a phase change material layer 22 on the outside of the inner liner 21, an outer liner 23 on the outside of the phase change material layer 22, a condenser pipe 25 connected to the top cover of the inner liner 21, the other end of the condenser pipe 25 being fixedly connected to one side of the inner liner 21, a valve 28 connected to the bottom of the inner liner 21, a discharge pipe 29 connected to the bottom of the valve 28, a filter chamber 30 in the middle section of the discharge pipe 29, and multiple sets of electric heating plates 24 at the bottom of the inner liner 21.
[0039] In use, the hemp seeds to be crushed are placed into the conical crushing chamber 1. The motor 4 drives the rotating shaft 5, along with the crushing disc 6, to rotate rapidly. While crushing the hemp seeds, the hemp seeds are also driven to move upwards in a spiral motion along the direction of the spiral guide plate 2 and against the inner wall of the conical crushing chamber 1 under the action of centrifugal force. This causes the hemp seeds to further collide with the fixed crushing blades 8. The first crushing blade 7 and the fixed crushing blades 8 work together to uniformly crush the hemp seeds. Hemp seed fragments that meet the standard particle size fall through the gap between the crushing disc 6 and the conical crushing chamber 1. The bottom of the conical crushing chamber 1 is fed into the hemp seed storage chamber 10 through the first conveying pipe 3. Hemp seed fragments that do not meet the crushing standard are conveyed upward again under the centrifugal force of the crushing disc 6 and circulated and crushed by the fixed crushing blade 8 until the particle size reaches the level that can pass through the gap between the crushing disc 6 and the conical crushing chamber 1, and then fall to the bottom of the conical crushing chamber 1. Through the above settings, the hemp seeds can be crushed evenly and the maximum particle size of the crushed hemp seeds can be controlled, which improves the consistency of the tea soup taste and the ability of the hemp seed components to be released when brewing tea.
[0040] Before brewing the tea, open the electrically controlled butterfly valves 12 at the bottom of the hemp seed storage chamber 10 and the ingredient storage chamber 11. This allows the materials in the hemp seed storage chamber 10 and the ingredient storage chamber 11 to enter the receiving chamber 17 inside the metering device 14 under gravity through the multi-port pipe 13. Note that the amount of material added to the receiving chamber 17 should be controlled according to the material ratio. By controlling the opening sequence of the electrically controlled butterfly valves 12, the materials are controlled to be discharged into the receiving chamber 17 in sequence according to their type. The weight sensor 15 can weigh the materials entering the receiving chamber 17 and display the weighing data on the display screen of the equipment control panel. By using the change in the weighing data of the weight sensor 15 after each type of material enters the receiving chamber 17, the timing of closing the electrically controlled butterfly valve 12 is determined to meet the requirements of the ratio accuracy.
[0041] After filling with water, seal the top of the water filling pipe with the sealing cap 27. This will allow the electric heating plate 24 to operate and heat the water inside the inner pot 21, starting the tea brewing process. The phase change material layer 22 is made of paraffin wax. As the water temperature rises, the phase change material layer 22 absorbs the heat conducted to the side wall of the inner pot 21. Before the surface temperature of the inner pot 21 reaches the melting point of the phase change material layer 22 (85 degrees Celsius), the phase change material layer 22 remains in a solid state, absorbing heat to slow down the rate of temperature rise inside the inner pot 21. To improve heating uniformity and avoid localized overheating, when the surface temperature of the inner liner 21 reaches the melting point of the phase change material layer 22, the phase change material layer 22 enters the phase change stage and begins to melt, absorbing a large amount of latent heat to offset the heat input from the electric heating plate 24. During the melting process, the temperature of the phase change material layer 22 is maintained at 85 degrees Celsius, ensuring a synchronous and stable water temperature inside the pipe. When excessive heating causes the internal temperature of the inner liner 21 to rise further, the phase change material layer 22 completely liquefies and stops absorbing heat, and the heat is dissipated to the outside through the outer liner 23. The phase change material layer 22 acts as a "thermal buffer pool," limiting temperature fluctuations to within ±2℃. Simultaneously, the steam generated during tea brewing enters the condenser tube 25 for condensation. The heat sink 26 effectively improves condensation efficiency. Since the inner pot 21 is sealed from the outside during tea brewing, the condenser tube 25 collects and condenses the steam, preventing excessive evaporation of water inside the inner pot 21 and reducing tea loss. Timely condensation of steam also prevents increased internal pressure due to tea vaporization and expansion, balancing the pressure and preventing explosions caused by excessive steam. Furthermore, the condensed water droplets flow back into the tea, working with the phase change material layer 22 to balance the internal temperature of the inner pot 21. Through the combined action of the phase change material layer 22 and the condenser tube 25, the water temperature inside the inner pot 21 is maintained at a suitable level, preventing overheating and boiling. This ensures the killing of bacteria while preventing the destruction of the effective components in the hemp seed due to overheating.
[0042] The conical crushing chamber 1 is equipped with a spiral guide plate 2 inside.
[0043] The spiral guide plate 2 is used to guide the flow direction of hemp seeds as they rise due to centrifugal force.
[0044] The top of the crushing disc 6 is provided with a plurality of first crushing blades 7 arranged in a ring, and the interior of the conical crushing chamber 1 is provided with a plurality of fixed crushing blades 8 arranged in a ring.
[0045] The rotation direction of the blade of the first crushing blade 7 is opposite to that of the blade of the fixed crushing blade 8, and both the blades of the first crushing blade 7 and the fixed crushing blade 8 are provided with serrations.
[0046] The rotation direction of the blade of the first crushing blade 7 is opposite to that of the blade of the fixed crushing blade 8. The hemp kernels, which are rotated and slide upward by the first crushing blade 7, can directly collide with the blade of the fixed crushing blade 8 for crushing. The serrated setting improves the crushing effect on the hemp kernels.
[0047] The quantitative device 14 is equipped with a weight sensor 15 inside. The weight sensor 15 is equipped with a support base 16 on top. The support base 16 is equipped with a receiving chamber 17 on top. An electric slide valve 18 is connected to the side of the receiving chamber 17. One end of the electric slide valve 18 is connected to the second delivery pipe 19.
[0048] Before brewing the tea, open the electrically controlled butterfly valves 12 at the bottom of the hemp seed storage chamber 10 and the ingredient storage chamber 11. This allows the materials in the hemp seed storage chamber 10 and the ingredient storage chamber 11 to enter the receiving chamber 17 inside the metering device 14 under gravity through the multi-port pipe 13. Note that the amount of material added to the receiving chamber 17 should be controlled according to the material ratio. By controlling the opening sequence of the electrically controlled butterfly valves 12, the materials are controlled to be discharged into the receiving chamber 17 in sequence according to their type. The weight sensor 15 can weigh the materials entering the receiving chamber 17 and display the weighing data on the display screen of the equipment control panel. By using the change in the weighing data of the weight sensor 15 after each type of material enters the receiving chamber 17, the timing of closing the electrically controlled butterfly valve 12 is determined to meet the requirements of the ratio accuracy.
[0049] The top cover of the inner liner 21 is connected to a water injection pipe, and the top of the water injection pipe is threadedly connected to a sealing cap 27.
[0050] After filling the inner liner 21 with water, use the sealing cap 27 to seal the water filling pipe to prevent water evaporation.
[0051] The filter chamber 30 has a filter slot on its inner side. The filter chamber 30 is connected to the filter 32 through the filter slot. One end of the filter 32 is fixed to the filter fixing plate 31.
[0052] When the fully brewed tea soup is discharged, the brewed material particles are intercepted by the filter screen 32 and remain in the filter chamber 30. The material residue can be cleaned by pulling out the filter screen fixing plate 31.
[0053] The top of the ingredient storage bin 11 is equipped with a feeding hopper 9.
[0054] The feed hopper 9 is designed to facilitate filling of ingredients into the feed storage bin 11.
[0055] The condenser tube 25 is provided with heat sink 26 on its outer side.
[0056] The heat sink 26 can absorb the heat that is conducted to the condenser tube 25 by the steam, and conduct the heat to the air through a large area of contact with the air, thereby improving the condensation efficiency of the condenser tube 25 for steam.
[0057] The working principle and usage process of this utility model are as follows: When using this device, the hemp kernels to be crushed are put into the conical crushing chamber 1. The motor 4 drives the rotating shaft 5 and the crushing disc 6 to rotate rapidly. While crushing the hemp kernels, the hemp kernels are driven to move upward in a spiral motion along the direction of the spiral guide plate 2 and against the inner wall of the conical crushing chamber 1 under the action of centrifugal force. This causes the hemp kernels to collide with the fixed crushing blades 8. The hemp kernels are uniformly crushed by the cooperation of the first crushing blade 7 and the fixed crushing blades 8. The hemp kernel fragments that meet the standard particle size fall through the gap between the crushing disc 6 and the conical crushing chamber 1 to the bottom of the conical crushing chamber 1 and are then transported into the hemp kernel storage chamber 10 through the first conveying pipe 3. The hemp kernel fragments that do not meet the crushing standard are... Under the centrifugal force of the crushing disc 6, the sesame seeds are conveyed upwards again and circulated through the fixed crushing blade 8 for further crushing until the particle size is large enough to pass through the gap between the crushing disc 6 and the conical crushing chamber 1. Then, they fall to the bottom of the conical crushing chamber 1. This setting ensures that the sesame seeds are evenly crushed and controls the maximum particle size after crushing, improving the consistency of the tea's flavor and the release of sesame seed components during brewing. The crushed sesame seed particles are stored inside the sesame seed storage chamber 10. If additional ingredients are needed, they can be added to the ingredient storage chamber 11 through the feed hopper 9 according to their type. Before brewing, the electrically controlled butterfly valve 12 at the bottom of the sesame seed storage chamber 10 and the ingredient storage chamber 11 is opened. Materials in the hemp seed storage bin 10 and the ingredient storage bin 11 can enter the receiving bin 17 inside the metering device 14 under gravity through the multi-port pipe 13. Note that the amount of material added to the receiving bin 17 should be controlled according to the material ratio. The material is sequentially discharged into the receiving bin 17 according to type by controlling the opening sequence of the electrically controlled butterfly valve 12. The weight sensor 15 can weigh the material entering the receiving bin 17 and display the weighing data on the display screen of the equipment control panel. The timing for closing the electrically controlled butterfly valve 12 is determined by the change in the weighing data of the weight sensor 15 after each type of material enters the receiving bin 17 to meet the ratio accuracy requirements. After the material ratio weighing is completed, the electric slide gate valve 18 can be opened to allow the receiving bin to... The material in section 17 is discharged into the inner liner 21 of the cooking tank 20 through the second conveying pipe 19. Then, water is injected into the inner liner 21 according to the mixing ratio through the water injection pipe at the top of the inner liner 21. After water injection, the top of the water injection pipe is sealed with the sealing cap 27. This allows the electric heating plate 24 to operate and heat the water inside the inner liner 21, starting the tea brewing process. The phase change material layer 22 is made of paraffin wax. After the water temperature rises, the phase change material layer 22 absorbs the heat conducted to the side wall of the inner liner 21. Before the surface temperature of the inner liner 21 reaches the melting point of the phase change material layer 22 (85 degrees Celsius), the phase change material layer 22 remains in a solid state, absorbing heat to slow down the rate of temperature rise inside the inner liner 21, improve heating uniformity, and prevent localized overheating.When the surface temperature of the inner liner 21 reaches the melting point of the phase change material layer 22, the phase change material layer 22 enters the phase change stage and begins to melt, absorbing a large amount of latent heat to offset the heat input by the electric heating plate 24. During the melting process, the temperature of the phase change material layer 22 is maintained at 85 degrees Celsius, keeping the water temperature inside the tube synchronously stable. When excessive heating causes the internal temperature of the inner liner 21 to rise further, the phase change material layer 22 completely liquefies and stops absorbing heat. The heat is dissipated to the outside through the outer liner 23. The phase change material layer 22 acts as a "thermal buffer pool," limiting temperature fluctuations to within ±2℃. At the same time, the steam generated during the tea brewing process enters the condenser pipe 25 for condensation. The condensation efficiency is effectively improved by the heat sink 26. Since the inner liner 21 is closed to the outside during tea brewing, the collection and condensation of steam through the condenser pipe 25 can prevent a large amount of water inside the inner liner 21 from evaporating, thus reducing the tea soup temperature. The timely condensation of steam prevents the internal pressure of the inner tank 21 from increasing due to the vaporization and expansion of the tea soup, thus balancing the pressure and preventing explosions caused by excessive internal pressure due to excessive steam. Simultaneously, the condensed water droplets flow back into the tea soup, working with the phase change material layer 22 to balance the internal temperature of the inner tank 21. Through the cooperation of the phase change material layer 22 and the condenser 25, the water temperature inside the inner tank 21 can be maintained at a suitable temperature, preventing overheating and boiling. This ensures the killing of bacteria while preventing the destruction of the effective components in the hemp seed due to overheating. After the tea soup is cooked, opening valve 28 allows the tea soup in the inner tank 21 to be discharged. The cooked material particles are intercepted by the filter screen 32 and remain in the filter chamber 30. Removing the filter screen fixing plate 31 allows for the cleaning of material residue.
