Description

Technical Field

[0001] The present invention relates to the technical field of herbal tea production, in particular to a mixing system and method for producing herbal tea beverages. Background Art

[0002] As a drink that accompanies people's daily life, herbal tea is guided by the health theory of traditional Chinese medicine and uses Chinese herbal medicine as raw materials. It has the effects of clearing away heat and detoxifying, promoting fluid production and quenching thirst, and removing fire and dampness. Therefore, it is deeply welcomed by the majority of users in my country.

[0003] Currently, traditional herbal tea ingredients primarily include white sugar, frangipani, grass jelly, buzia leaves, chrysanthemum, honeysuckle, licorice, and selfheal. The production process involves pouring these ingredients into a container in a specific ratio, adding an appropriate amount of water, and bringing the mixture to a boil over high heat. The mixture is then heated for ten minutes to complete the boiling process. After the boiling process is complete, the residue is removed, and the liquid is filtered through a filter container to remove any solid residue. Finally, an appropriate amount of white sugar is added to the resulting liquid for flavoring. The flavored liquid is then refrigerated to create the herbal tea beverage.

[0004] Nowadays, in the herbal tea production process, since there are many types of raw materials that need to be boiled, and each raw material needs to be mixed with water in a certain proportion, before boiling, each raw material must be weighed first, and then poured into the heating tank in sequence. Since the raw materials need to be weighed each time herbal tea is boiled, the process before boiling is relatively cumbersome and requires a high degree of manual participation, which is not conducive to improving the production efficiency of herbal tea beverages. To this end, we propose a mixing system and method for herbal tea beverage production to effectively address the above-mentioned drawbacks. Summary of the Invention

[0041] The following will provide a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0042] Example 1: Please refer to Figure 1 - Figure 10A mixing system for producing herbal tea beverages includes a batching mechanism 100, a heating tank 200, a filtering tank 300, and a mixing tank 400; wherein the batching mechanism 100 includes a plurality of batching tanks 101, each of which is used to contain various ingredients, and the heating tank 200 is used to steam various ingredients, and a feeding hopper 201 is provided on the top of the heating tank 200; the batching mechanism 100 also includes a chain plate conveyor belt 102, which is supported by a support The frame is fixedly arranged above the heating tank 200, and the conveying surface of the chain conveyor belt 102 is distributed in the vertical direction. One of the conveying surfaces of the chain conveyor belt 102 is located directly above the top of the feed hopper 201, and the other conveying surface is located obliquely above the feed hopper 201. Several batching tanks 101 are distributed at intervals on the conveying surface of the chain conveyor belt 102, and the discharge port of the batching tank 101 is set vertically downward, and the bottom end of the batching tank 101 is higher than the top surface of the feed hopper 201.

[0043] Specifically in this embodiment, white sugar, frangipani, grass jelly, shaddock leaves, chrysanthemum, honeysuckle, liquorice, and selfheal are placed in the plurality of ingredient tanks 101. In addition, the above plant ingredients all need to be dried and chopped into small pieces for easy discharging.

[0044] Furthermore, the input end of the filter tank 300 is connected to the output end of the heating tank 200 through a pipeline, and the filter tank 300 is used to filter the medicinal liquid after being cooked in the heating tank 200; the input end of the mixing tank 400 is connected to the output end of the filter tank 300; when the medicinal liquid filtered by the filter tank 300 is passed into the interior of the mixing tank 400, an appropriate amount of white sugar needs to be added for seasoning.

[0045] In order to realize the automatic discharging function by moving the batching tank 101 to the upper side of the feed hopper 201, the structures of the batching tank 101 and the feed hopper 201 are described in detail below:

[0046] The axial direction of the batching tank 101 is vertically distributed, and a discharge pipe 103 is provided at the bottom end of the batching tank 101 so as to slide in the vertical direction. The bottom end of the discharge pipe 103 extends to the outside of the batching tank 101, and the bottom end of the discharge pipe 103 is elastically connected to the bottom wall of the batching tank 101 via a tension spring 104. An anti-overflow ring 105 is sleeved on the inside of the batching tank 101 and located outside the discharge pipe 103. Pull rods 106 are symmetrically provided on both sides of the outer wall of the discharge pipe 103. The pull rods 106 are distributed in the horizontal direction. The anti-overflow ring 105 and the side wall of the batching tank 101 are jointly provided with movable openings 107 for the pull rods 106 to pass through. Two pull rods 106 pass through the two movable openings 107 and extend to the outside of the batching tank 101. Specifically in this embodiment, the top of the anti-overflow ring 105 is a concave structure, which is used to facilitate the material to enter the discharge pipe 103; in addition, in the natural state, the tension spring 104 is in a tensioned state, and the pulling rod 106 abuts against the inner upper edge of the movable port 107; when the pulling rod 106 abuts against the inner lower edge of the movable port 107, the top of the discharge pipe 103 is still higher than the movable port 107.

[0047] In addition, a cover plate 202 is provided on the top surface of the feed hopper 201, and a leakage channel 203 is provided in the middle position of the cover plate 202. The leakage channel 203 is located directly below the corresponding material tank 101, and vertical plates 205 are symmetrically provided on the left and right sides of the top surface of the cover plate 202. The distance between the two vertical plates 205 is greater than the diameter of the discharge pipe 103, and the facing surfaces of the two vertical plates 205 are provided with a wiring groove 206 that is compatible with the pull rod 106. The wiring groove 206 is a three-section structure consisting of a first inclined section 2061, a horizontal section 2062 and a second inclined section 2063, and the wiring groove 206 is high at both ends and low in the middle. When the material tank 101 passes between the two vertical plates 205, the pull rod 106 can move along the path of the wiring groove 206, and the discharge pipe 103 first descends and then ascends. That is, the height of the starting end of the wiring groove 206 is consistent with the height of the pull rod 106 in the initial state, ensuring that the pull rod 106 can smoothly enter the wiring groove 206.

[0048] In some embodiments of the present application, an electric on-off valve 108 is provided on the inner side of the bottom of the discharge pipe 103. Two leads of the electric on-off valve 108 are respectively connected to two pull rods 106, which are made of a conductive material. A conductive strip 207 is provided in each of the horizontal sections 2062 of the two vertical plates 205. The two conductive strips 207 are respectively connected to the positive and negative poles of a power supply (a DC power supply is used, not shown in the figure). When the pull rods 106 enter the horizontal sections 2062, they abut the corresponding conductive strips 207. Therefore, when both pull rods 106 enter the horizontal sections 2062 simultaneously, the electric on-off valve 108 is energized and opened, allowing material to be discharged from the bottom of the discharge pipe 103. When the electric on-off valve 108 is de-energized, the valve plate returns to its original position and closes under the action of the spring force, thereby preventing the material from continuing to fall.

[0049] It should be noted that the pull rod 106 is made of copper, the batching tank 101, the discharge pipe 103 and the anti-overflow ring 105 are all made of insulating materials such as plastic. The conductive strip 207 is made of conductive materials such as copper or aluminum, and the vertical plate 205 is made of insulating materials such as ceramic.

[0050] In this embodiment, under normal conditions, the electric switch valve 108 is always in a closed state, and the material in the batching tank 101 cannot flow out; when the batching tank 101 moves between the two vertical plates 205, first, under the drive of the wiring groove 206, the discharge pipe 103 descends and its bottom end extends into the leakage channel 203, and secondly, under the action of the conductive bar 207, the electric switch valve 108 is energized and opened, and the material is discharged from the bottom end of the discharge pipe 103, thereby completing the discharge; when the pull rod 106 moves to the inside of the second inclined section 2063, the electric switch valve 108 is de-energized and closed, and the discharge stops.

[0051] In order to enable the discharge pipe 103 to release a fixed amount of material, the internal structure of the feed hopper 201 is described below:

[0052] A displacement sleeve 208 is provided inside the feed hopper 201 for sliding along the conveying direction of the chain conveyor belt 102. The displacement sleeve 208 is an open structure at both ends, and the axial direction of the displacement sleeve 208 is distributed along the vertical direction. The displacement sleeve 208 is located in the leakage channel 203. A material receiving sleeve 209 is also provided inside the displacement sleeve 208, and the material receiving sleeve 209 and the displacement sleeve 208 are axially slidably matched; that is, the material receiving sleeve 209 can slide up and down inside the displacement sleeve 208, but cannot twist relative to the displacement sleeve 208.

[0053] Furthermore, mounting ears 210 are provided on both the left and right sides of the exterior of the displacement sleeve 208, and a polished rod 211 is slidably provided on the mounting ears 210. The polished rod 211 is fixedly connected to the inner wall of the feed hopper 201 and distributed along the length direction of the material leakage channel 203. A return spring 212 is also sleeved on the exterior of the polished rod 211, and the two ends of the return spring 212 abut against the inner wall of the feed hopper 201 and the mounting ears 210 respectively. In a natural state, the return spring 212 is in a compressed state, and the displacement sleeve 208 is located in the material leakage channel 203 and faces the side close to the starting end of the chain plate conveyor belt 102. That is, under the thrust of the return spring 212, when the displacement sleeve 208 is not affected by external forces of the system, the displacement sleeve 208 is always located on the side close to the starting end of the chain plate conveyor belt 102. Specifically, the starting end is the starting end of a conveying surface of the chain plate conveyor belt 102 located directly above the feed hopper 201.

[0054] The diameter of the receiving sleeve 209 is larger than the diameter of the discharge pipe 103. The top of the receiving sleeve 209 is symmetrically provided with docking rings 213 on the left and right sides. The docking ring 213 is a sheet structure with a through hole in the middle. The top surface of the docking ring 213 is fixedly embedded with a first annular magnetic ring 214, and the first magnetic ring 214 is located at the through hole on the docking ring 213. The bottom surface of the material tank 101 is symmetrically provided with docking columns 109 for inserting into the docking ring 213 on the left and right sides. The bottom end of the docking column 109 is pointed, and the outside of the docking column 109 is also provided with an extension sleeve 110. The extension sleeve 110 is fixedly connected to the bottom wall of the material tank 101. The bottom surface of the extension sleeve 110 is provided with a second magnetic ring 111. The facing poles of the first magnetic ring 214 and the second magnetic ring 111 are different. Therefore, when the material tank 101 moves between the two vertical plates 205 and is located directly above the material receiving sleeve 209, the material receiving sleeve 209 can be driven to rise under the attraction of the first magnetic ring 214 and the second magnetic ring 111 until the first magnetic ring 214 and the second magnetic ring 111 are in contact with each other. At this time, the docking column 109 can be inserted into the docking ring 213, thereby carrying the material receiving sleeve 209 and the displacement sleeve 208 to move synchronously.

[0055] The facing surfaces of the two vertical plates 205 are each provided with a routing rail 215, which is located below the second inclined section 2063 and has a high front and low back posture. When the displacement sleeve 208 moves between the two routing rails 215, the two docking rings 213 respectively abut against the lower surfaces of the two routing rails 215; when the docking rings 213 abut against the ends of the routing rails 215, the bottom end of the discharge pipe 103 is higher than the top end of the material receiving sleeve 209. Specifically in this embodiment, when the material receiving sleeve 209 moves to the position of the routing rail 215 along with the material tank 101, the routing rail 215 will abut against the upper surface of the docking ring 213, thereby driving the material receiving sleeve 209 to move downward, separating it from the material tank 101.

[0056] In some embodiments of the application, a blocking ring 216 is provided on the inner side of the bottom of the displacement sleeve 208. When the displacement sleeve 208 is in the initial state, the bottom end of the material receiving sleeve 209 abuts against the blocking ring 216. A blocking plate 217 is provided on the inner side of the bottom of the material receiving sleeve 209. A leakage hole 218 is opened through the blocking plate 217. A movable slot 219 is also opened on the inner side of the blocking plate 217. A pull-out plate 220 is provided inside the movable slot 219. The pull-out plate 220 is elastically connected to the inside of the movable slot 219 by a compression spring 221. The side wall of the displacement sleeve 208 is provided with a hole for the pull-out plate 220 to pass through. The pull-out plate 220 is provided with a discharge hole 223 through the through opening 222; when the displacement sleeve 208 is located in the leakage channel 203 and faces the side close to the starting end of the chain conveyor belt 102, the outer end of the pull-out plate 220 abuts against the inner wall of the feed hopper 201, and the discharge hole 223 and the leakage hole 218 are aligned, and the compression spring 221 is in a compressed state at this time; when the pull-out plate 220 is not in contact with the inner wall of the feed hopper 201, under the action of the compression spring 221, the pull-out plate 220 pops outward, and the discharge hole 223 and the leakage hole 218 are staggered, and the leakage hole 218 no longer discharges material.

[0057] On the other hand, a guide ring is provided on the top surface of the sealing plate 217. The top surface of the guide ring is concave, and the inner diameter of the guide ring is equivalent to the inner diameter of the leakage hole 218, so as to facilitate the leakage of materials.

[0058] Specifically, in the initial state, when the batching tank 101 moves to the position just above the displacement sleeve 208, under the magnetic attraction of the first magnetic ring 214 and the second magnetic ring 111, the material receiving sleeve 209 rises and is adsorbed on the bottom of the batching tank 101. At this time, the pulling rod 106 has not yet entered the wiring groove 206; as the batching tank 101 continues to move, it will carry the material receiving sleeve 209 and the displacement sleeve 208 to move synchronously. When the pulling rod 106 enters the first inclined section 2061, the pulling plate 220 does not contact the inner wall of the feed hopper 201. At this time, the leakage hole 218 is in a sealed state. Closed state; when the pull rod 106 enters the interior of the horizontal section 2062, the bottom end of the discharge pipe 103 extends into the material receiving sleeve 209, and the electric switch valve 108 is energized and opened, and the material in the material tank 101 enters the material receiving sleeve 209 through the discharge pipe 103; then, when the pull rod 106 enters the interior of the second inclined section 2063, the electric switch valve 108 is de-energized and closed, and the discharge pipe 103 gradually rises. At the same time, under the driving action of the wiring rail 215, the material receiving sleeve 209 moves downward and separates from the material tank 101, and the docking post 109 is pulled out of the docking ring 213. Finally, the pull rod 106 moves out from the end of the second inclined section 2063, and the displacement sleeve 208 is reset to its initial state under the action of the return spring 212. When the displacement sleeve 208 is reset to its initial state, the pull-out plate 220 is squeezed by the inner wall of the feed hopper 201 , so that the leakage hole 218 and the discharge hole 223 are aligned, and the material can be discharged smoothly and enter the heating tank 200 through the feed hopper 201 .

[0059] It is worth mentioning that when the pull rod 106 is located within the horizontal section 2062, that is, when the discharge pipe 103 is unloading, since the material is in the form of small solid pieces, the material can only be filled in the area between the sealing plate 217 and the bottom end of the discharge pipe 103, thereby achieving the function of quantitative discharge. On the other hand, in this embodiment, the length of the extension sleeve 110 at the bottom end of different batching tanks 101 varies, that is, the thickness of the area between the bottom end of the discharge pipe 103 and the sealing plate 217 in different batching tanks 101 varies, thereby meeting the requirements of different material discharge quantities.

[0060] Example 2: This embodiment of the present application also provides a method for preparing a herbal tea beverage, which is applicable to the herbal tea beverage preparation system in Example 1, and includes the following steps:

[0061] Start the chain conveyor belt 102 to drive several batching tanks 101 to pass over the feed hopper 201 in sequence, and each batching tank 101 releases an appropriate amount of ingredients into the feed hopper 201 when passing over the feed hopper 201; the bottom of the discharge pipe 103 is provided with an electric switch valve 108. When the batching tank 101 enters between the two vertical plates 205 and the pulling rod 106 abuts against the conductive bar 207, the electric switch valve 108 is energized and opened, thereby automatically discharging the material.

[0062] After the ingredients are added, add an appropriate amount of water into the heating tank 200 and start boiling. Continue heating for 90 minutes after boiling.
