Description

Technical Field

[0001] The invention relates to the technical field of multifunctional health-care tea preparation, in particular to a method for preparing multifunctional health-care tea with a high yield. Background Art

[0002] Functional health tea is a tea product made by scientifically combining different types of tea leaves with other plant materials. Due to its rich raw materials and diverse production methods, multifunctional health tea has multiple health benefits that can meet the health needs of different groups of people. It has the effects of anti-oxidation, improving intestinal function, enhancing immunity, and nourishing health.

[0003] The existing production process of functional health tea includes raw material preparation, pretreatment, effective ingredient extraction, mixing and molding, drying and packaging. When pretreating the health tea, the screened tea leaves need to be withered for 4-6 hours at a temperature of 20-25°C and a relative humidity of 60-70% to make the tea lose some moisture and reduce cell activity, which is convenient for subsequent processing. The tea leaves are then withered using high-temperature steam at a temperature of 180-220°C for 1-2 minutes to destroy the enzyme activity in the tea leaves and fix the quality of the tea leaves.

[0004] When the tea leaves are withered, the tea leaves that need to be withered are vibrated and screened through a vibrating screen and conveyed to the next processing procedure. When the tea leaves enter the vibrating screen through the feeding port, the tea leaves are easy to accumulate on the vibrating screen, and the tea leaves accumulated on the vibrating screen cannot be flattened. The tea leaves accumulated on the feeding port of the vibrating screen are easy to cause uneven heating of the tea leaves during the withering process, and the withered tea leaves will also accumulate on the feeding port of the vibrating screen before entering the next processing procedure. The tea leaves accumulated on the feeding port of the vibrating screen are easy to cause the heat of the tea leaves after withering to not be dissipated in time, thereby causing the tea leaves to be over-withered or under-withered, thereby reducing the quality of tea production.

DETAILED DESCRIPTION

[0030] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0031] The present invention provides a technical solution: Figures 1 to 7 As shown, in this embodiment, a method for preparing multifunctional health tea with a high yield is provided, which is achieved by a steam fixing device and specifically comprises the following steps:

[0032] Step 1: The tea leaves are delivered to the inlet of the vibrating screen 408 by an external feeding device, and then the driving motor 101 and the servo motor 507 are turned on;

[0033] Step 2: The driving motor 101 drives the vibrating screen 408 to vibrate and convey the tea leaves toward the discharge port. During this process, the servo motor 507 drives the flattening paddle 503 to flatten the tea leaves so that the tea leaves are fully exposed to the steam.

[0034] Step 3: The flattening paddle 503 located at the discharge port flattens the tea leaves after withering. The vibration force generated by the driving motor 101 on the vibrating screen 408 can also shake off the water droplets condensed and attached on the steam bin 2.

[0035] The screened tea leaves are withered for 4-6 hours at a temperature of 20-25°C and a relative humidity of 60-70%. This causes the tea leaves to lose some moisture and reduce cell activity, making them easier to process. The tea leaves are then withered using a steam-dried tea plant at a temperature of 180-220°C for 1-2 minutes to destroy enzyme activity and maintain tea quality.

[0036] Then, water extraction, filtration, concentration and other steps are performed to obtain a concentrated solution.

[0037] After obtaining the concentrated liquid, an appropriate amount of auxiliary materials is added to the concentrated liquid for mixing. After the mixing is completed, the mixed material is granulated by a granulator, the granulation temperature is controlled at 60-70°C, and the granulation speed is 20-30 revolutions per minute to prepare granular health tea.

[0038] The steps of water extraction, filtration, concentration, etc. in the above process are all existing technologies and will not be disclosed in detail here.

[0039] The steam fixing device includes a support base 1, a heating mechanism 3, a screening mechanism 4 and a flattening mechanism 5. A driving motor 101 is fixedly installed on the side of the support base 1 away from the outer wall of the steam bin 2 through a mounting plate. The output shaft of the driving motor 101 is fixedly sleeved with a first rotating wheel 102. The end of the support base 1 away from the first rotating wheel 102 is fixedly sleeved with a second rotating wheel 103 through an axis rod. A belt 104 is wrapped around the surface of the first rotating wheel 102, and the end of the belt 104 away from the first rotating wheel 102 is wrapped around the surface of the second rotating wheel 103.

[0040] When the tea leaves need to be withered, the conveying mechanism first conveys the tea leaves to the surface of the feeding port of the vibrating screen 408, and then starts the driving motor 101. The driving motor 101 drives the first rotating wheel 102 to rotate, and the rotating first rotating wheel 102 drives the second rotating wheel 103 to rotate through the belt 104. The rotating first rotating wheel 102 and the second rotating wheel 103 drive the two sets of rotating rods 404 to rotate on the inner sides of the two sets of connecting seats 403, so that the rotating rotating rods 404 drive the two sets of eccentric blocks 405 to rotate.

[0041] like Figure 1 、 Figure 2 、 Figure 3 and Figure 7 As shown, a steam bin 2 is fixedly installed on one side of the outer wall of the support base 1, a guide cover 201 is fixedly installed on the top of the inner wall of the steam bin 2, a discharge pipe 202 is installed through the top of the steam bin 2, and collection tanks 203 are fixedly installed on both sides of the inner wall of the steam bin 2, and both ends of the two groups of collection tanks 203 are connected with guide pipes 204, and first connecting blocks 205 are equidistantly installed on both sides of the inner wall of the steam bin 2, and the tops of several groups of first connecting blocks 205 are fixedly connected with sleeve rods 206.

[0042] During the rising process of steam, part of the steam is discharged through the discharge pipe 202. During the steam discharge process, the steam will cool and condense into water droplets. The water droplets flow downward along the deflector 201, and the downward-flowing water droplets flow downward along the inner wall of the steam bin 2. It should be noted that the vibration force of the vibrating screen 408 drives several groups of second connecting blocks 409 to vibrate synchronously. Several groups of synchronously vibrating second connecting blocks 409 drive the steam bin 2 to vibrate through several groups of sleeve rods 206 and several groups of first connecting blocks 205, so that the water droplets attached to the inner wall of the steam bin 2 can flow downward quickly. The flowing water droplets flow along the inner wall of the steam bin 2 into the inside of the two groups of collection tanks 203. At the same time, the water collected in the collection tank 203 is guided to the inside of the water storage tank 304 through two groups of guide pipes 204, so as to facilitate the recycling and reuse of the water droplets condensed from the steam.

[0043] like Figure 1 、 Figure 2 and Figure 3 As shown, the bottom of the inner side of the steam bin 2 is provided with a heating mechanism 3 for withering the tea leaves, and the heating mechanism 3 includes a base 301, which is fixedly mounted on the bottom end of the inner side of the steam bin 2, a heat conducting plate 302 is fixedly mounted on the top end of the inner side of the base 301, a heating tube 303 is fixedly mounted on the bottom end of the heat conducting plate 302, a water reservoir 304 is fixedly mounted on the top end of the heat conducting plate 302, heat conducting rods 305 are equidistantly arranged inside the water reservoir 304, and discharge ports 306 are equidistantly arranged on the top end of the water reservoir 304, and receiving screens 307 are fixedly mounted on the top ends of several groups of discharge ports 306, and the top ends of several groups of heat conducting rods 305 pass through the interiors of several groups of discharge ports 306 and contact the bottom ends of the receiving screens 307.

[0044] The external power supply of the heating tube 303 is started, and the heating tube 303 generates heat energy, which is conducted to the inside of the water tank 304 through the heat conducting plate 302. It should be noted that water is stored in the water tank 304, and the heat energy conducted by the heat conducting plate 302 heats the water inside the water tank 304. After the water is heated, steam is generated. The steam continues to rise through several groups of discharge ports 306 and the mesh holes opened in the receiving screen 307. The rising steam passes through the mesh holes opened in the vibrating screen 408 and steam-fixes the tea leaves in the middle position of the vibrating screen 408.

[0045] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6As shown, the double layer of the steam bin 2 near the heating mechanism 3 is provided with a screening mechanism 4 for screening and conveying tea leaves, and the screening mechanism 4 includes a support column 401, and the support column 401 is provided in two groups. The two groups of support columns 401 are both provided at both ends away from the outside of the steam bin 2, and the tops of the two groups of support columns 401 are fixedly installed with spring seats 402, and the ends of the two groups of spring seats 402 away from the two groups of support columns 401 are fixedly connected with connecting seats 403, and the two groups of connecting seats 403 are rotatably connected with a rotating rod 404. The surfaces of the rotating rods 404 are fixedly sleeved with eccentric blocks 405. The outer sides of the two rotating rods 404 near the two eccentric blocks 405 are fixedly sleeved with outer shells 406. The tops of the two connecting seats 403 are fixedly connected to the mounting frames 407 through the two spring seats 402. The interiors of the two mounting frames 407 are fixedly installed with vibrating screens 408. Second connecting blocks 409 are equidistantly installed on both sides of the outer walls of the mounting frames 407. The interiors of several sets of second connecting blocks 409 are sleeved on the surfaces of several sets of sleeve rods 206.

[0046] The two sets of rotating eccentric blocks 405 rotate inside the two sets of outer shells 406 to generate centrifugal force. The centrifugal force generated by the two sets of eccentric blocks 405 acts on the spring seats 402 at the upper and lower ends of the two sets of connecting seats 403. The elastic force of several sets of spring seats 402 is used to drive the installation frame 407 and the vibrating screen 408 to vibrate, so that the vibrating vibrating screen 408 can transmit the vibration of the tea leaves at its feed port to the middle position thereof, so that the tea leaves are exposed to steam and steam-killing is performed on the tea leaves.

[0047] like Figure 1 、 Figure 3 and Figure 7 As shown, both ends of the screening mechanism 4 are provided with a flattening mechanism 5 for flattening the tea leaves, and the flattening mechanism 5 includes a connecting frame 501 and a servo motor 507. The connecting frames 501 are provided in three groups, wherein the top ends of two groups of connecting frames 501 are connected to both sides of the steam bin 2 through cross bars, and the top end of one group of connecting frames 501 is fixedly mounted on the top end of the inner wall of the steam bin 2, and the inner sides of the three groups of connecting frames 501 are all rotatably mounted with connecting rods 502, and the bottom ends of the three groups of connecting rods 502 are all fixedly connected with a flattening paddle 503, and the bottom ends of the three groups of flattening paddles 503 are all connected to the vibrating screen 4. 08, one end of the three groups of connecting rods 502 are fixedly connected to the rotating shaft 504, the three groups of rotating shafts 504 are all arranged on the outside of the three groups of connecting frames 501, the three groups of rotating shafts 504 are hinged to the end of the three groups of connecting rods 502 with the rocker 505, and one end of the rocker 505 is hinged to the connecting rod 506, the bottom end of the servo motor 507 is installed on the outer wall of the support base 1 through the mounting base, the output shaft of the servo motor 507 is fixedly sleeved with an eccentric wheel 508, and the end of the eccentric wheel 508 away from the servo motor 507 is hinged to one end of the connecting rod 506,

[0048] While the vibrating screen 408 is rotating and conveying, the servo motor 507 is started, and the servo motor 507 drives the eccentric wheel 508 to rotate. The rotating eccentric wheel 508 drives the connecting rod 506 to rotate. The rotating connecting rod 506 drives the three sets of rotating shafts 504 to swing on the outside of the connecting frame 501 through the rocker 505. The three sets of swinging rotating shafts 504 drive the three sets of connecting rods 502 to swing on the inside of the three sets of connecting frames 501. The three sets of swinging connecting rods 502 drive the three sets of flattening grates 503 to swing on the top of the vibrating screen 408. Among them, the two sets of flattening grates 503 near the inlet of the vibrating screen 408 flatten the tea leaves accumulated at the inlet of the vibrating screen 408. To prevent tea leaves from piling up at the inlet of the vibrating screen 408, the tea leaves are spread out on the surface of the inlet of the vibrating screen 408. After the tea leaves at the top middle of the vibrating screen 408 are withered by steam, the vibrating screen 408 vibrates and transmits the tea leaves at the top middle of the vibrating screen 408 to the outlet of the vibrating screen 408. At this time, the flattening paddle 503 at the outlet of the vibrating screen 408 is always in a swinging state. The swinging flattening paddle 503 swings and flattens the tea leaves at the outlet of the vibrating screen 408, so as to flatten and dissipate heat of the tea leaves after withering, and avoid the heat accumulation in the tea leaves after withering for a long time, which causes the tea leaves to be over-withered, thereby affecting the subsequent processing quality of the tea leaves.

[0049] The raw materials of health tea are: Ganoderma lucidum, Cordyceps sinensis, Astragalus membranaceus, Honeysuckle, Pueraria root, Dendrobium officinale, Chrysanthemum morifolium, Pu'er tea, Cassia seed, Jasmine, Poria cocos, Anoectochilus roxburghii, Momordica grosvenori, Buddha's hand, and Ziziphus jujuba seeds.

[0050] It should be noted that the main ingredient of the above-mentioned health tea is Pu'er.

[0051] It should be noted that the mesh of the receiving screen 307 is smaller than the mesh of the vibrating screen 408, which makes it easier for impurities smaller than tea leaves to be screened out from the mesh of the vibrating screen 408. Since the mesh of the receiving screen 307 is smaller than the mesh of the vibrating screen 408, it can receive the screened impurities.

[0052] The present invention provides a method for making multifunctional health-care tea with a high yield rate. The specific working principle is as follows: when tea leaves need to be withered, the tea leaves are first conveyed to the surface of the feeding port of the vibrating screen 408 by the conveying mechanism, and then the driving motor 101 is started. The driving motor 101 drives the first rotating wheel 102 to rotate, and the rotating first rotating wheel 102 drives the second rotating wheel 103 to rotate through the belt 104. The rotating first rotating wheel 102 and the second rotating wheel 103 drive two groups of rotating rods 404 to rotate inside the two groups of connecting seats 403. The rotating rotating rods 404 drive two groups of eccentric blocks 405 to rotate. The two groups of rotating eccentric blocks 405 rotate inside the two groups of outer shells 406 to generate centrifugal force. The centrifugal force generated by the two groups of eccentric blocks 405 acts on the spring seats 402 at the upper and lower ends of the two groups of connecting seats 403. The elastic force of the plurality of groups of spring seats 402 is used to drive the mounting frame 407 and the vibrating screen 408 to vibrate, and the vibrating vibrating screen 408 vibrates and transmits the tea leaves at its feeding port to the middle position thereof.

[0053] While the vibrating screen 408 is rotating and conveying, the servo motor 507 is started, and the servo motor 507 drives the eccentric wheel 508 to rotate. The rotating eccentric wheel 508 drives the connecting rod 506 to rotate, and the rotating connecting rod 506 drives the three groups of rotating shafts 504 to swing on the outside of the connecting frame 501 through the rocker 505. The three groups of swinging rotating shafts 504 drive the three groups of connecting rods 502 to swing on the inside of the three groups of connecting frames 501. The three groups of swinging connecting rods 502 drive the three groups of spreading grates 503 to swing on the top of the vibrating screen 408. Among them, the two groups of spreading grates 503 near the feeding port of the vibrating screen 408 flatten the tea leaves accumulated at the feeding port of the vibrating screen 408 to prevent the tea leaves from accumulating at the feeding port of the vibrating screen 408, so that the tea leaves are spread evenly on the surface of the feeding port of the vibrating screen 408.

[0054] When the vibrating screen 408 is fed with material, the tea leaves are flattened, and the vibration force of the vibrating screen 408 transmits the tea leaves to the top of the middle of the vibrating screen 408. At this time, the external power supply of the heating tube 303 is started, and the heating tube 303 generates heat energy, which is conducted to the inside of the water storage tank 304 through the heat conduction plate 302. It should be noted that water is stored in the water storage tank 304, and the heat energy conducted by the heat conduction plate 302 heats the water in the water storage tank 304. After the water is heated, steam is generated. The steam continues to rise through the mesh holes of the receiving screen 307 through several groups of discharge ports 306. The rising steam passes through the mesh holes of the vibrating screen 408 and steam-fixes the tea leaves in the middle of the vibrating screen 408. In order to prevent the steam from cooling down during the rising process, the bottom ends of the several groups of heat-conducting rods 305 are in contact with the top ends of the heat-conducting plates 302, and the top ends of the several groups of heat-conducting rods 305 are in contact with the bottom ends of the receiving screens 307, so that the several groups of heat-conducting rods 305 can transfer the heat energy conducted by the heat-conducting plates 302 to the receiving screens 307, thereby keeping the steam warm and preventing the steam from cooling down during the rising process. At the same time, when the vibrating screen 408 vibrates and conveys the tea leaves, impurities in the tea leaves fall onto the surface of the receiving screen 307 through the meshes of the vibrating screen 408. When too much impurities accumulate on the surface of the receiving screen 307, the staff can use a cleaning tool to clean the impurities accumulated on the top of the receiving screen 307.

[0055] After the tea leaves on the top of the vibrating screen 408 are withered by steam, the tea leaves on the top of the vibrating screen 408 are vibrated and transmitted to the discharge port of the vibrating screen 408 as the vibrating screen 408 vibrates. At this time, the flattening grater 503 at the discharge port of the vibrating screen 408 is always in a swinging state. The swinging flattening grater 503 swings and flattens the tea leaves at the discharge port of the vibrating screen 408, which is convenient for flattening and dissipating heat of the withered tea leaves, thereby preventing the heat in the withered tea leaves from accumulating for a long time, causing the tea leaves to be over-withered, thereby affecting the subsequent processing quality of the tea leaves.

[0056] After the steam has withered the tea leaves on the top of the vibrating screen 408, the steam continues to rise. During the rising process, part of the steam is discharged through the exhaust pipe 202. During the steam discharge process, the steam will cool and condense into water droplets. The water droplets flow downward along the guide cover 201, and the downward-flowing water droplets flow downward along the inner wall of the steam bin 2. It should be noted that the vibration force of the vibrating screen 408 drives several groups of second connecting blocks 409 to vibrate synchronously. Several groups of synchronously vibrating second connecting blocks 409 drive the steam bin 2 to vibrate through several groups of sleeve rods 206 and several groups of first connecting blocks 205, so that the water droplets attached to the inner wall of the steam bin 2 can flow downward quickly. The flowing water droplets flow along the inner wall of the steam bin 2 into the two groups of collecting troughs 203. At the same time, the water collected in the collecting trough 203 is guided to the inside of the water storage tank 304 through two groups of guide pipes 204, so as to facilitate the recycling and reuse of the water droplets condensed by the steam.
