Description

Technical Field

[0001] The utility model belongs to the technical field of extract processing, and particularly relates to a ginkgo leaf extract processing device. Background Art

[0002] Ginkgo biloba extract is a product derived from the dried leaves of Ginkgo biloba, a plant of the Ginkgo family, using appropriate solvents to enrich the active ingredients. Ginkgo biloba extract has the effects of promoting blood circulation, removing blood stasis, and unblocking meridians. It is widely used in pharmaceuticals, health supplements, food additives, functional beverages, and cosmetics.

[0003] The processing steps for ginkgo leaf extract primarily include a preparatory stage, extraction, filtration, distillation, concentration, and drying. During the preparatory stage, fresh ginkgo leaves are first washed, air-dried, and then placed in a drying oven for drying. The drying time varies depending on the sample's moisture content. After drying, the leaves are cooled in the drying oven for subsequent processing.

[0004] However, the existing drying oven has low cooling efficiency, so it takes a long time to cool down the drying oven and the ginkgo leaves after drying. This not only easily reduces the working efficiency of the drying oven, but also affects the subsequent extraction of the ginkgo leaves.

[0005] Therefore, in view of the above technical problems, it is necessary to provide a ginkgo leaf extract processing device.

[0006] The information disclosed in this background technology section is only intended to increase the understanding of the overall background of the present invention, and should not be regarded as an admission or any form of suggestion that the information constitutes the prior art already known to those skilled in the art. Utility Model Content

[0007] The purpose of the utility model is to provide a ginkgo leaf extract processing device, which can solve the problem of slow cooling efficiency of a ginkgo leaf drying box.

[0008] In order to achieve the above-mentioned purpose, the technical solution provided by a specific embodiment of the present invention is as follows:

[0009] A ginkgo leaf extract processing device comprises: a drying oven main body, an auxiliary cooling mechanism and a cover;

[0010] A working chamber is provided in the drying box body, an exhaust port is installed on the top wall of the drying box body, and an air inlet is provided on the side wall of the drying box body, and the working chamber is connected to the outside world through the exhaust port and the air inlet respectively;

[0011] The auxiliary cooling mechanism is installed on the side wall of the drying box body, and the auxiliary cooling mechanism includes a cooling box, a first partition is provided in the cooling box, a processing chamber and a cooling chamber are formed between the inner wall of the cooling box and the first partition, a gas pre-treatment mechanism is provided in the processing chamber, a cooling liquid is provided in the cooling chamber, ice is provided in the cooling liquid, the gas pre-treatment mechanism corresponds to the cooling liquid, and a connecting pipe is connected to the cooling box;

[0012] The cover is installed on the side wall of the drying box body and covers the air inlet hole. The cover is communicated with the connecting pipe.

[0013] In one or more embodiments of the present invention, a second partition is installed in the processing chamber, and the processing chamber is divided into an air suction chamber and a drying chamber by the second partition. The air suction chamber is used to install an air suction pump, and the drying chamber is used to install drying cotton and an activated carbon layer.

[0014] In one or more embodiments of the present invention, the gas pretreatment mechanism includes an air suction pump, which is installed in the air suction chamber. An air outlet pipe is connected to the air suction pump, and one end of the air outlet pipe is arranged in the cooling chamber. When the air suction pump is running, the air suction pump will absorb external gas and transport the gas to the cooling chamber through the air outlet pipe.

[0015] In one or more embodiments of the present invention, the cooling box is provided with an air intake port and a heat dissipation port, the air intake cavity is connected to the outside world through the air intake port and the heat dissipation port, the air intake pump can absorb external gas through the air intake port, and the air intake pump can dissipate heat through the heat dissipation port, so that the air intake pump is not prone to high temperature during operation.

[0016] In one or more embodiments of the present invention, one end of the air outlet pipe located in the cooling liquid is connected to a straight pipe, and a number of evenly distributed nozzles are installed on the straight pipe. The gas transported by the air outlet pipe will enter the straight pipe and be discharged through the number of nozzles, so that the gas can evenly enter the cooling liquid and use the cooling liquid for cooling. At the same time, the gas also has a stirring effect on the cooling liquid, so that the temperature of the cooling liquid is uniform and temperature differences are less likely to occur.

[0017] In one or more embodiments of the present invention, a plurality of flow holes are provided on the first partition plate, the drying chamber is connected with the cooling chamber through the flow holes, and the gas cooled by the cooling liquid enters the drying chamber through the flow holes.

[0018] In one or more embodiments of the present invention, a pair of grids are installed in the drying chamber, and drying cotton and activated carbon layers are respectively provided on the pair of grids. One end of the connecting pipe is arranged on the upper side of the activated carbon layer. The drying cotton and the activated carbon layer are both used to dry the gas, so that the gas is not easy to carry water vapor, thereby ensuring the dryness of the gas entering the working chamber and not easily affecting the dried ginkgo leaves.

[0019] In one or more embodiments of the present invention, the cooling box is provided with a feeding port and a material replacement port, the feeding port corresponding to the cooling chamber, so that ice cubes can be added into the cooling liquid through the feeding port;

[0021] In one or more embodiments of the present invention, a sealing plate is slidably provided on the cover, and the sealing plate covers the air inlet. When the ginkgo leaves are dried in the working chamber, the sealing plate covers the air inlet, making it difficult for hot air in the working chamber to enter the cover through the air inlet, thereby reducing the loss of heat energy resources.

[0022] A handle is installed on the sealing plate to facilitate the movement of the sealing plate.

[0023] In one or more embodiments of the present invention, a locking screw is threadedly connected to the sealing plate, and the locking screw corresponds to the drying box body. When the ginkgo leaves in the working chamber need to be cooled, the handle is held to slide the sealing plate inside the cover. At this time, the sealing plate no longer covers the air inlet hole, and the locking screw can be used to fix the position of the sealing plate.

[0024] Compared with the prior art, the ginkgo leaf extract processing device of the present invention can accelerate the cooling efficiency of the drying box and the ginkgo leaves, thereby improving the working efficiency of the drying box and is less likely to affect the subsequent extraction of the ginkgo leaves.

DETAILED DESCRIPTION

[0034] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the following will be combined with the drawings of the embodiments of the present invention to clearly and completely describe the technical solutions of the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.

[0035] like Figures 1 to 6 As shown, a ginkgo leaf extract processing device in one embodiment of the present invention includes a drying box body 1, an auxiliary cooling mechanism 2 and a cover 3.

[0036] Preferably, the drying oven body 1 is a commercially available electric heating blast drying oven.

[0037] The drying box body 1 has a working chamber 101 in which ginkgo leaves are placed to dry for subsequent ginkgo leaf extraction. An exhaust port 102 is installed on the top wall of the drying box body 1 to exhaust the hot air in the working chamber 101.

[0038] In addition, the sidewall of the drying oven body 1 is provided with an air inlet 103, and the working chamber 101 is connected to the outside world through the exhaust port 102 and the air inlet 103. When the suction pump 203 is in operation, the gas sucked by the suction pump 203 enters the working chamber 101 through the air inlet 103, increasing the pressure of the gas in the working chamber 101. This allows the gas in the working chamber 101 to be quickly discharged through the exhaust port 102, thereby quickly reducing the temperature of the ginkgo leaves. At the same time, the suction pump 203 delivers low-temperature gas, which further cools the ginkgo leaves in the working chamber 101.

[0039] like Figures 1 to 6 As shown, the auxiliary cooling mechanism 2 is installed on the side wall of the drying box body 1. The auxiliary cooling mechanism 2 can accelerate the cooling rate of the working chamber 101 and the ginkgo leaves in the working chamber 101, thereby improving the working efficiency of the drying box body 1 so that the ginkgo leaves can be subsequently extracted and processed.

[0040] The auxiliary cooling mechanism 2 includes a cooling box 201, which is provided with a first partition 202. A processing chamber and a cooling chamber are formed between the inner wall of the cooling box 201 and the first partition 202. A second partition is installed in the processing chamber, dividing the processing chamber into an air intake chamber and a drying chamber. The air intake chamber is used to install an air pump 203, and the drying chamber is used to install drying cotton 210 and an activated carbon layer 211.

[0041] like Figures 1 to 6 As shown, a gas pretreatment mechanism is provided in the processing chamber, which can cool the absorbed gas so that the gas temperature is lower than the ambient temperature, and dry the cooled gas so that the gas entering the working chamber 101 does not carry water vapor and is not likely to affect the dried ginkgo leaves.

[0042] The gas pre-processing mechanism includes an air pump 203 installed in the air intake chamber. Connected to the air pump 203 is an air outlet pipe 204, one end of which is located in the cooling chamber. When the air pump 203 is running, it draws in ambient air and delivers it to the cooling chamber through the air outlet pipe 204.

[0043] In addition, cooling box 201 is provided with an air intake port 205 and a heat dissipation port 213. The air intake chamber is connected to the outside world through air intake port 205 and heat dissipation port 213. Air pump 203 can draw in external air through air intake port 205 and dissipate heat through heat dissipation port 213, making it less likely for air pump 203 to reach high temperatures during operation.

[0044] Specifically, a cooling liquid 206 is provided in the cooling chamber, and ice is contained in the cooling liquid 206. The gas pre-treatment mechanism corresponds to the cooling liquid 206. By adding ice to the cooling liquid 206, the temperature of the cooling liquid 206 can be lowered below the ambient temperature. When the gas drawn by the suction pump 203 enters the cooling liquid 206, the gas is cooled, thereby ensuring that the subsequent gas quickly cools the ginkgo leaves in the working chamber 101.

[0045] At the same time, after the gas sucked by the suction pump 203 enters the cooling liquid 206 , dust in the gas can also be removed, making it difficult for dust to enter the working chamber 101 .

[0046] Preferably, the cooling liquid 206 is water.

[0047] like Figures 1 to 6 As shown, one end of the outlet pipe 204 located within the cooling liquid 206 is connected to a straight pipe 207, on which several evenly distributed nozzles are mounted. Gas transported by the outlet pipe 204 enters the straight pipe 207 and is discharged through the nozzles, allowing the gas to evenly enter the cooling liquid 206 and be cooled by the cooling liquid 206. The gas also stirs the cooling liquid 206, ensuring a uniform temperature and minimizing temperature differences.

[0048] The first partition plate 202 is provided with a plurality of flow holes 208 , and the drying chamber is connected to the cooling chamber through the flow holes 208 . The gas cooled by the cooling liquid 206 enters the drying chamber through the flow holes 208 .

[0049] Furthermore, a pair of grids 209 are installed within the drying chamber. These grids are each equipped with drying cotton 210 and an activated carbon layer 211. One end of a connecting tube 212 is positioned above the activated carbon layer 211. Both the drying cotton 210 and the activated carbon layer 211 are used to dry the gas, preventing it from carrying moisture. This ensures the dryness of the gas entering the working chamber 101, minimizing the risk of damage to the dried ginkgo leaves.

[0050] Preferably, the drying cotton 210 and the activated carbon layer 211 are both commercially available products and can be purchased and used directly.

[0051] Specifically, the cooling box 201 is connected to a connecting pipe 212 , and the dried gas is continuously transported through the connecting pipe 212 .

[0052] like Figures 1 to 6 As shown, the cooling box 201 is provided with a feeding port 214 and a refill port 215. The feeding port 214 corresponds to the cooling chamber, allowing ice cubes to be added to the cooling liquid 206. The refill port 215 corresponds to the drying chamber, allowing the drying cotton 210 and / or the activated carbon layer 211 to be replaced.

[0053] like Figures 1 to 6 As shown, the cover 3 is mounted on the side wall of the drying oven body 1 and covers the air inlet 103. The cover 3 is connected to the connecting pipe 212. The gas transported by the connecting pipe 212 enters the cover 3 and then enters the working chamber 101 through the air inlet 103, thereby rapidly cooling the ginkgo leaves in the working chamber 101.

[0054] A sealing plate 301 is slidably mounted on the cover 3, covering the air inlet 103. When the ginkgo leaves are drying in the working chamber 101, the sealing plate 301 covers the air inlet 103, preventing hot air from entering the cover 3 through the air inlet 103, thereby reducing heat loss.

[0055] In addition, a handle is installed on the sealing plate 301 to facilitate the movement of the sealing plate 301.

[0056] Specifically, a locking screw 302 is threadedly connected to the sealing plate 301, and the locking screw 302 corresponds to the drying box body 1. When the ginkgo leaves in the working chamber 101 need to be cooled, the handle is held to slide the sealing plate 301 in the cover 3. At this time, the sealing plate 301 no longer covers the air inlet 103, and the locking screw 302 can be used to fix the position of the sealing plate 301.

[0057] In practical use, after the ginkgo leaves are dried in working chamber 101, suction pump 203 is operated to draw in ambient air. The air then enters straight pipe 207 through outlet pipe 204 and is then discharged into cooling liquid 206 through a number of nozzles. Because cooling liquid 206 contains ice, its temperature is lower than the ambient temperature. As the air enters cooling liquid 206, it is cooled.

[0058] The cooled gas enters the drying chamber through the circulation hole 208 , and enters the cover 3 through the connecting pipe 212 under the drying effect of the drying cotton 210 and the activated carbon layer 211 .

[0059] Gripping the handle on sealing plate 301, the sealing plate 301 slides within cover 3. At this point, sealing plate 301 no longer covers air inlet 103, and locking screw 302 secures the sealing plate 301. Air within cover 3 enters working chamber 101 through air inlet 103, rapidly cooling the ginkgo leaves within working chamber 101 with the low-temperature air. This improves the efficiency of drying oven body 1 and minimizes the impact on subsequent extraction of the ginkgo leaves.

[0060] The gas in the working chamber 101 will eventually be exhausted through the exhaust port 102 , so that the gas pressure in the working chamber 101 is not likely to be too high.

[0061] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.

[0062] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
