Description

Technical Field

[0001] The invention belongs to the technical field of ginkgo leaf extraction, and in particular relates to a soft capsule containing ginkgo leaf extract, a preparation device and a process thereof. Background Art

[0002] Ginkgo leaf extract has the functions of improving cardiovascular health, protecting the nervous system, anti-oxidation, and improving eyes. If used according to doctor's instructions, it can effectively prevent and help improve some health problems related to cardiovascular, nervous, and eye health.

[0003] Ginkgo biloba extract is generally prepared by fermentation, soaking, filtration, concentration and drying to obtain natural medicinal ingredients. Fermentation is an important prerequisite for extraction. Fermentation can effectively separate the effective substances in ginkgo leaves, making it easier to obtain solid natural medicinal ingredients through subsequent soaking, filtration, concentration and drying.

[0004] However, during the fermentation process, the fermented ginkgo leaves tend to accumulate. At this time, the squeezing of the fermented materials will lead to local oxygen deficiency, which is not conducive to the fermentation of the ginkgo leaves.

[0005] In the process of soaking the ginkgo leaves, in order to release the natural medicinal ingredients in the ginkgo leaves into the water as much as possible, squeezing is generally used. The soaked ginkgo leaves are taken out, squeezed, and then soaked repeatedly. This cycle is repeated many times, and the substances in the ginkgo leaves are discharged as much as possible through squeezing.

[0006] However, this method has certain disadvantages. Since the factory generally soaks a large amount of ginkgo leaves, the ginkgo leaves are taken out and squeezed, and then put back into the water to soak. This process is time-consuming, and there is a possibility that the crushed ginkgo leaves will stick to the crushing device and need to be cleaned. These will affect the factory's processing efficiency and are not conducive to the factory's production. Summary of the Invention

[0023] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0024] Example: Refer to Figures 1-11 A preparation device for soft capsules containing ginkgo leaf extract, comprising an extraction tank 1 and a fermentation tank 4, further comprising: a spiral groove 401, arranged in the fermentation tank 4; an air bag 5, slidably connected to the fermentation tank 4, a limit block 501 matching the spiral groove 401 is installed on the air bag 5, and multiple groups of air outlets 503 with solenoid valves are provided on the air bag 5; multiple groups of stirring rods 502 are fixedly connected in the air bag 5; an air pump 7, fixedly connected to the fermentation tank 4, and an air inlet pipe 701 and an air outlet pipe 702 are connected to the air inlet end and the air outlet end of the air pump 7 respectively, the air inlet pipe 701 is connected to the outside, and the air outlet pipe 702 is connected to the air bag 5. , and the air outlet pipe 702 is a telescopic hose; the air pump 7 continuously draws nitrogen and inflates the air bag 5, which can inflate the air bag 5 located in the ginkgo leaf fermentation mixture, and then under the action of the limit block 501, the air bag 5 moves along the spiral groove 401, causing the stirring rod 502 to rotate synchronously to stir the ginkgo leaf fermentation material in the fermentation tank 4; a material pump 6 is fixedly connected to the bottom of the fermentation tank 4, and the feed end and discharge end of the material pump 6 are respectively connected to a feed pipe 601 and a discharge pipe 602, the feed pipe 601 is connected to the discharge end of the fermentation tank 4, and the discharge pipe 602 is connected to the feed end of the extraction tank 1.

[0025] When the device is in use, the washed and dried ginkgo leaves are introduced into the fermentation tank 4, and then water is added to moisten the ginkgo leaves and maintain the water content at 50%-60%. An appropriate amount of fermentation bacteria is added, and the fermentation bacteria can be Aspergillus oryzae or Aspergillus niger. Then, the temperature of the fermentation tank 4 is adjusted to between 30°C and 37°C to facilitate the fermentation of the ginkgo leaves.

[0026] During fermentation, the air pump 7 is started. A separate nitrogen tank is required for nitrogen, and the nitrogen temperature should not be too low, otherwise it will affect the fermentation environment. Nitrogen is injected into the airbag 5, which then expands, and the buoyancy increases, and the airbag 5 moves upward along the spiral groove 401, thereby causing the stirring rod 502 to rotate synchronously to stir the ginkgo leaf fermentation product in the fermentation tank 4. Finally, the solenoid valve can be opened to discharge some gas and restore the airbag 5. The stirring rod 502 itself is heavy and can be easily sunk back into the ginkgo leaf fermentation product, or it can be kept at the top. Because there is no need to stir all the time, only occasional stirring is needed to make the bacteria uniform.

[0027] After the fermentation is completed, the ginkgo leaves can be fed into the extraction tank 1 through the material pump 6 .

[0028] like Figure 1-9 As shown, the motor 101 is fixedly connected to the extraction tank 1, and a rotating shaft 102 is rotatably connected in the extraction tank 1. The rotating shaft 102 is fixedly connected to the output end of the motor 101, and multiple groups of rolling shafts 2 are rotatably connected in the extraction tank 1. The rolling shaft 2 is attached to the side wall of the extraction tank 1. When the rotating shaft 102 rotates, the rolling shaft 2 rotates along the side wall of the extraction tank 1. The water pump 3 is fixedly connected to the bottom of the extraction tank 1. The liquid inlet end and the liquid outlet end of the water pump 3 are respectively connected to the liquid inlet pipe 301 and the liquid outlet pipe 302. The liquid inlet pipe 301 is used to suck the liquid inside the extraction tank 1. The bottom of the extraction tank 1 is provided with multiple groups of liquid outlet holes 304 along the rotating shaft 102. The liquid outlet holes 304 are communicated with the liquid outlet pipe 302. The liquid outlet holes 304 are used to blow the ginkgo leaves accumulated in the middle area to the surrounding areas. A drainage pipe 201 is provided at the axis of the rolling shaft 2, and multiple groups of suction holes 204 are provided along the circumference of the rolling shaft 2. The liquid hole 204 is connected to the drain pipe 201, and the drain pipe 201 is connected to the liquid inlet pipe 301. A plurality of empty slots 202 are provided along the circumference of the rolling shaft 2. The longitudinal liquid suction holes 204 are all provided in the empty slots 202. The empty slots 202 are connected with the filter screen 203. The rotating shaft 102 is fixedly connected with a connecting rod 103. The rolling shaft 2 is rotatably connected to the connecting rod 103. An inner tube 1031 is provided in the connecting rod 103. The inner tube 1031 is used to connect The drainage pipe 201 and the liquid inlet pipe 301 are connected, and a connecting pipe 303 is connected to the extraction tank 1. The two ends of the connecting pipe 303 are respectively connected to the liquid outlet 304 and the liquid outlet pipe 302. A one-way valve is provided in the liquid outlet pipe 302. The liquid outlet pipe 302 is tilted to guide the ginkgo leaves in the middle to the outside. An electronic valve 205 is provided in the liquid suction hole 204. The electronic valve 205 is located at one end of the liquid suction hole 204 close to the drainage pipe 201.

[0029] An encoder can be provided on the rolling shaft 2 in the present device, so that the rotation position of the rolling shaft 2 can be specifically known. The extraction tank 1 is an existing stirring tank with a heating function, and the liquid inlet and the liquid outlet are respectively equipped with sealing covers.

[0030] When the device is in use, the fermented crushed ginkgo leaves are put into the extraction tank 1, and then a suitable amount of water is poured in. The water should generally overflow the rolling shaft 2, and the heating function of the extraction tank 1 is started to heat the water and keep the temperature at about 50 degrees Celsius, 60 degrees Celsius is the best. Then, the sealing cover of the liquid inlet is closed, and the motor 101 is turned on. At this time, the start of the motor 101 will cause the rotating shaft 102 to rotate, and the rotation of the rotating shaft 102 will cause the rolling shaft 2 to rotate along the inner wall of the extraction tank 1. At this time, the rolling shaft 2 will play a stirring role, thereby causing the water in the extraction tank 1 to flow, and the water The flow will cause the ginkgo leaves to flow as well. During this process, the substances in the ginkgo leaves will gradually flow into the water. At the same time, since the rolling shaft 2 is in contact with the inner wall of the extraction tank 1, the rolling shaft 2 will squeeze some of the ginkgo leaves in the water between the rolling shaft 2 and the inner wall of the extraction tank 1, and then the water adsorbed by the ginkgo leaves will be discharged by squeezing, and the effective substances in the ginkgo leaves will flow out as the ginkgo leaves are squeezed. Subsequently, the squeezed ginkgo leaves on the rolling shaft 2 move away from the extraction tank 1, allowing the ginkgo leaves to re-absorb water. The cycle continues until 30 minutes later, when the stirring is completed, the tea is taken out to obtain the extract.

[0031] During the fermentation process, the fermentation materials are regularly turned or stirred to ensure the supply of oxygen and the uniformity of the fermentation. At the same time, parameters such as temperature, humidity and pH value are monitored during the fermentation process to ensure that they are within the appropriate range. If the pH value changes significantly, it can be adjusted by adding an appropriate amount of acid or alkali.

[0032] During the rotation of the rolling shaft 2, the rotation of the rolling shaft 2 will generate an impact force, which will cause the liquid to move away from the rolling shaft 2. At this time, some ginkgo leaves in the water will be affected by this impact force and move away from the rolling shaft 2 and cannot be crushed by the rolling shaft 2. At this time, the water pump 3 can be started synchronously. Figure 4 As shown, it is connected to the discharge pipe 201 of the rolling shaft 2. At this time, the water pump 3 will continuously absorb the external water through the suction hole 204. During the adsorption process, the ginkgo leaves that would originally flow away with the force generated by the impact will be sucked by this adsorption force and then remain on the filter 203. Figure 6 、 Figure 7 、 Figure 8 As shown, the filter 203 is installed on the empty groove 202, and there is a certain gap between the suction hole 204 and the filter 203. Therefore, even if a large number of ginkgo leaves are attached to the filter 203, water will still flow into the drainage hole 201 through the empty groove 202 and the filter 203. At this time, these adsorbed ginkgo leaves will be relatively firmly located on the filter 203, waiting to be squeezed by the rolling shaft 2 and the inner wall of the extraction tank 1 to discharge the internal liquid, and then come into contact with water again to re-absorb water. This cycle will continue until the time is up and the liquid is discharged.

[0033] During the rotation of the rolling shaft 2, if the ginkgo leaves are always in one area, if the ginkgo leaves on the filter 203 are in a stacked state, then the ginkgo leaves in the middle will find it difficult to absorb water. Therefore, the position of the rolling shaft 2 can be obtained in real time through the encoder. Alternatively, the position of each vertical row of drainage pipes 201 on the rolling shaft 2 can be obtained by other means without using the encoder, such as Figure 7 As shown, the empty slots 202 are arranged longitudinally, and the longitudinal empty slots 202 are arranged at equal intervals. In this way, if the real-time position of one group of empty slots 202 is known, the positions of the other empty slots 202 can be known. At this time, the positions of the various rolling shafts 2 can be continuously transmitted through the encoder. When the filter screen 203 on a group of empty slots 202 on the rolling shaft 2 is close to the inner wall of the extraction tank 1, the ginkgo leaves are squeezed and the water is discharged. At this time, the electronic valve 205 in the empty slot 202 is closed, and the empty slot 202 will no longer absorb water from the outside, that is, it will no longer generate suction to absorb these filter screens 203. At the same time, since the crushing shaft 2 continues to rotate, these ginkgo leaves will move away from the side wall of the extraction tank 1 and then flow with the water flow back into the liquid. When the empty slot 202 rotates a certain angle, which can range from 90 degrees to 180 degrees, the electronic valve 205 can be reopened to absorb water again, adsorbing the ginkgo leaves in the external water and adsorbing them on the filter 203, making it easier to squeeze the ginkgo leaves again and drain the internal water. In this way, the separation of the ginkgo leaves and the filter 203 can be controlled, reducing the situation where the ginkgo leaves are always attached and piled up.

[0034] During the start-up process of the water pump 3, the water pump 3 will continuously suck water from the extraction tank 1 through the suction hole 204 and finally discharge it through the liquid outlet 304. At this time, the discharged water will, through impact, blow the ginkgo leaves accumulated in the middle area during the stirring process to the surrounding area, making it easier for the surrounding rolling shafts 2 to better squeeze these ginkgo leaves.

[0035] Reference Figure 6-Figure 8 In a more preferred embodiment, the electronic valves 205 are all located at one end of the suction hole 204 close to the discharge pipe 201, and the suction hole 204 is connected to a connecting pipe 206. The suction holes 204 located in the same empty slot 202 are all connected through the connecting pipe 206.

[0036] During the rotation, the crushing shaft 2 is in close contact with the side wall of the extraction tank 1. The squeezed ginkgo leaves are squeezed tightly and adhere to the filter 203, making it difficult to separate. At this time, the electronic valve 205 can be controlled. After the ginkgo leaves are squeezed and dehydrated by rotation, all the electronic valves 205 in the same vertical column are closed, and no adsorption force is generated, so that the ginkgo leaves are separated from the filter 203. At the same time, the rotation of the motor 101 increases, thereby increasing the rotation speed of the crushing shaft 2. The water in the suction hole 204 is discharged by centrifugation, and the water stored in the connecting pipe 206 will also be discharged, increasing the impact force of the water flow, and blowing away the ginkgo leaves remaining on the filter 203.

[0037] Reference Figure 3 In a more preferred embodiment, a plurality of arc-shaped flow-pushing plates 104 are fixedly connected to the rotating shaft 102. The arc-shaped flow-pushing plates 104 are away from the liquid outlet 304 at the bottom. The arc-shaped flow-pushing plates 104 are used to push the liquid in the middle area of ​​the extraction tank 1 to the surrounding areas.

[0038] like Figure 3 As shown, the device is provided with an arc-shaped push flow plate 104. When the arc-shaped push flow plate 104 rotates along the rotating shaft 102, it can guide the water in the middle to the outside through the arc-shaped surface. At this time, the ginkgo leaves piled in the middle can flow to the edge along the flow of the liquid.

[0039] The end of the arc-shaped flow-pushing plate 104 away from the rotating shaft 102 can be set at the front end of the rolling shaft 2 in the forward direction, so that the liquid can be directly guided to the rolling shaft 2, making it easier for the rolling shaft 2 to absorb and squeeze the ginkgo leaves.

[0040] A process for preparing soft capsules containing ginkgo leaf extract, and equipment for preparing soft capsules containing ginkgo leaf extract, comprising the following steps: Step 1: Place the washed and dried ginkgo leaves into a fermentation tank 4 and add water to maintain the water content of the ginkgo leaves at 50%-60%; Step 2: Add fermentation bacteria into the fermentation tank 4. The fermentation bacteria can be fungi (such as Aspergillus oryzae, Aspergillus niger) or bacteria (such as Bacillus) that have the ability to decompose cellulose or produce specific enzymes. The inoculation amount can be controlled at 5%-10% of the weight of the ginkgo leaves, and the temperature is controlled at 30°C-37°C. The fermentation time is generally 3-7 days. Step 3: The fermented ginkgo leaf mixture is transported to the extraction tank 1 through the material pump 6 for extraction to obtain an extract; Step 4: filtering and purifying the extracted liquid, and finally concentrating and drying it to obtain a solid extract of ginkgo leaves; Step 5: Mix the ginkgo leaf extract with excipients, such as gelatin, glycerin, and water, which are used to prepare soft capsules. Appropriate amounts of antioxidants (such as vitamin E) and sunscreens (such as titanium dioxide) may also need to be added to ensure product stability and quality. The soft capsule material is made by adding gelatin, glycerin, and water in a certain ratio (usually gelatin: glycerin: water = 1:0.4 - 0.6:1 - 1.2) into a reactor, heating to 60-70°C, stirring evenly to fully dissolve the gelatin and form a uniform gel solution. Add appropriate amounts of antioxidants, sunscreens, and other excipients, continue stirring and mixing evenly, keep the gel solution warm and let it stand for a period of time to remove bubbles in the gel solution to obtain a clear and transparent soft capsule material gel solution, and finally use a soft capsule forming machine for production.

[0041] When the soft capsules are prepared by the soft capsule forming machine, the soft capsules are formed by the soft capsule forming machine. The prepared capsule material glue and ginkgo extract liquid are respectively added to the corresponding hoppers of the soft capsule forming machine. The capsule material glue is evenly coated on the rotating mold with a certain thickness through the nozzle of the forming machine. At the same time, the ginkgo extract liquid is quantitatively injected into the capsule shell formed by the glue. The mold is closed so that the glue wraps the liquid to form a soft capsule. During the forming process, the temperature of the glue, the speed and pressure of the nozzle and other parameters must be controlled to ensure the quality and appearance of the soft capsule.

[0042] Finally, the soft capsules are dried in a drying room. The drying temperature is generally controlled at 25-35°C and the relative humidity is 30%-40%. During the drying process, good ventilation is required to allow the moisture in the soft capsules to evaporate gradually and the capsule shells to harden. Drying time usually takes several hours to dozens of hours, depending on the size and thickness of the soft capsules.

[0043] A soft capsule containing ginkgo leaf extract is prepared by adopting a preparation process of a soft capsule containing ginkgo leaf extract.

[0044] The present invention provides an air bag 5 that can move up and down and rotate in a fermentation tank 4, and then stirs the fermented material through a stirring rod 502 on the air bag 5, so that the fermented material is fermented evenly. At the same time, a rolling shaft 2 that rotates along the side wall of the extraction tank 1 can generate suction to adsorb the ginkgo leaves floating in the water, and then squeeze them through contact with the side wall of the extraction tank 1 to discharge the water. There is no need to fish out the ginkgo leaves, and the ginkgo leaves on the rolling shaft 2 do not need to be cleaned, thereby improving work efficiency and facilitating the extraction of the ginkgo leaves.

Although the present invention has been disclosed as above in terms of a preferred embodiment, it is not intended to limit the present invention. Any technician familiar with this patent can make slight changes or modifications to equivalent embodiments using the above technical content without departing from the scope of the technical solution of the present invention.
