Description

Technical Field

[0001] The utility model relates to the technical field of bamboo processing equipment, in particular to a bamboo sap extraction device, which is a device for obtaining bamboo sap from bamboo materials by means of hot pressing. Background Art

[0002] Bamboo sap is the liquid naturally leached out from some bamboos, such as moso bamboo and light bamboo, after heat processing. It can be used as food and Chinese medicinal materials. The various amino acids, trace elements and guaiacol contained in it make it have the effects of clearing heat and reducing phlegm, relieving cough and clearing lung heat. Bamboo sap can be prepared by a variety of methods. In addition to the traditional burning method and the legal dry distillation method, there are also new emerging percolation method, reflux method, steaming method, rolling method, etc., each of which has its own advantages and disadvantages.

[0003] Traditional bamboo sap extraction methods have their own shortcomings. The burning method has problems such as low bamboo sap extraction, environmental pollution, and low production efficiency. In addition, it can only be burned on-site at the bamboo material collection site and is not suitable for off-site processing. In particular, bamboo treated by the burning method cannot be reused, which to a certain extent causes a waste of bamboo resources. The bamboo sap extracted by the steaming method and the rolling method contains almost no major effective ingredients (especially guaiacol), so the obtained bamboo sap products do not have the effects of clearing heat and reducing phlegm. In particular, for the rolling method, the distillation, purification and other processes after the rolling process are too complicated and the production efficiency is extremely low.

[0004] The legal dry distillation method is to remove the nodes at both ends of a bamboo section of about 30 cm in length, split it in half, and then place it in an inclined position or hang it vertically. Burn it with an open flame in the middle, place ignited charcoal around it for heating, and collect the liquid flowing out. In modern enterprises, mechanical equipment is used for gas or electric heating to automatically control the temperature, dry distillation time and flow rate. For example, the method disclosed in the Chinese utility model patent application with publication number CN 114272330 A and the name "A method for extracting fresh bamboo juice without smoke" is to feed a bamboo strip with a length of 80 cm and a width of 6 cm into a direct fire extraction device (i.e., a direct fire dry distillation device). The front end temperature of the direct fire extraction device is 500-800°C, the rear end temperature is 350-480°C, and the feeding speed of the bamboo strip in the device is 0.1-0.5m / s. After condensation, about 50g of bamboo juice can be obtained per kilogram of fresh bamboo. This technical solution uses a high front-end temperature to evaporate the water molecules in the bamboo slices or the organic components in the vascular bundles in a very short time, and a low back-end temperature to minimize the carbonization of the outer surface of the bamboo slices. However, this method has the problems of high temperature and high energy consumption, and the mechanical properties of the bamboo slices after treatment are seriously reduced, which affects the utilization of the bamboo slices.

[0005] In summary, the prior art lacks a bamboo sap extraction device with relatively high production efficiency, which can achieve mass production, has a relatively high bamboo sap yield, and the bamboo material after the bamboo sap is extracted can still be used with high added value.

[0032] In order to enable those skilled in the art to better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of this application.

[0033] Example: Refer to Figure 1 , Figure 2 A bamboo sap extraction device is shown, which is improved based on the flat plate press 1 of the prior art. As the main component of the bamboo sap extraction device, the flat plate press 1 has a composition roughly the same as that of the prior art, including a frame 11, a lower pressing plate 12, an upper pressing plate 13, a power unit 14, a pressing plate heating unit, and a control cabinet. Among them, the frame 11 is a press frame of the prior art, such as a cast iron frame structure, suitable for installing the lower pressing plate 12, the upper pressing plate 13, the power unit 14 and the pressing plate heating unit. The frame 11 is open in the x-axis direction to facilitate loading and unloading. The lower pressing plate 12 is a flat plate pressing plate of the prior art, which is fixedly mounted on the frame 11. The upper pressing plate 13 is a flat plate pressing plate of the prior art, which is arranged opposite to the pressure surface of the lower pressing plate 12 and can be raised and lowered by the drive of the power unit 14. The width of the lower pressing plate 12 and the upper pressing plate 13 is 3m (width in the y-axis direction) × 0.5m (depth in the x-axis direction). Of course, according to the needs of use, the lower pressing plate 12 and the upper pressing plate 13 can have other set widths. The power unit 14 is of prior art, such as a pair of oil cylinders, fixedly mounted on the top of the frame 11, and the output end is connected to the upper pressing plate 12 to drive the lifting of the upper pressing plate 12. Since the extraction of bamboo sap does not require a relatively high pressure, by adopting a pair of oil cylinders, it can not only ensure that the lower pressing plate 12 is uniformly compressed everywhere, but also reduce the total weight of the device. The pressing plate heating unit is also of prior art, such as a hot oil system, which is circulated and connected to the lower pressing plate 12 and the upper pressing plate 13 through an insulated high-temperature resistant pipeline, and hot oil is introduced into the lower pressing plate 12 and the upper pressing plate 13 to heat both. The control cabinet is a PLC control cabinet of prior art.

[0034] Different from the flat press 1 of the prior art, the bamboo sap extraction device of this embodiment also includes a bamboo sap collection tank 2 and a bamboo sap collection tank 3. The bamboo sap collection tank 2 is at least arranged on one side of the x-axis direction of the lower pressing plate 12. In order to collect the bamboo sap precipitated from both ends of the bamboo slices 7 at the same time, the bamboo sap collection tank 2 includes a pair, which are respectively arranged on the upper and lower sides of the lower pressing plate 12, and the setting height of the bamboo sap collection tank 2 is lower than the pressure surface of the lower pressing plate 12. The bamboo sap collection tank 3 may include two, which are respectively connected to the two bamboo sap collection tanks 2 located on the upper and lower sides by pipelines, or may only include one, which is connected to the bamboo sap collection tanks 2 on both sides by pipelines. For example, in this embodiment, the bamboo sap collection tanks 2 on both sides converge from their tail ends through pipelines to the main pipeline and then flow into the bamboo sap collection tank 3. Those skilled in the art know that in order to enable the bamboo sap in the bamboo sap collection tank 2 to always flow toward the bamboo sap collection tank 3, a connecting vessel, a valve, etc. are selected to be used in conjunction with the pipeline.

[0035] By means of the above structure, the bamboo slice 7 from which bamboo juice is to be extracted is placed on the lower pressing plate 12, so that the length direction of the bamboo slice 7 is in the same direction as the x-axis direction, and both ends of the bamboo slice 7 are extended out of the width of the lower pressing plate 12 and are located above the bamboo juice collecting tank 2. The upper pressing plate 13 is closed, and under the action of heat and pressure, bamboo juice can be precipitated from both ends of the bamboo slice 7, and the bamboo juice is collected at both ends of the bamboo slice 7. The collected bamboo juice flows into the bamboo juice collecting tank 3 for the next step of processing. The bamboo sap extraction device of the present embodiment can simultaneously apply high temperature and pressure to the bamboo chips 7, so that the bamboo chips 7 can precipitate bamboo sap at a faster speed, and the production efficiency of bamboo sap is high and mass production can be achieved; at the same time, with the cooperation of pressure, more bamboo sap can be obtained, and the bamboo sap yield can be improved; in particular, due to the pressure effect of the bamboo chips 7 on the flat pressure surfaces of the lower pressing plate 12 and the upper pressing plate 13, the bamboo chips 7 are flattened as the bamboo sap is extracted, and the flat bamboo chips 7 can be suitable as raw materials for high value-added products such as bamboo finger-jointed boards, bamboo chopsticks, bamboo cutting boards, and bamboo spoons.

[0036] Reference Figure 3 As shown, the bamboo sap collecting tank 2 includes a collecting tank body 21 arranged along the y-axis direction, and a groove cavity 22 opened along the y-axis direction is provided in the collecting tank body 21. The groove cavity 22 is a blind groove, and the groove bottom is an inclined surface and an outlet is provided at the lowest point. In order to facilitate the connection with the bamboo sap collecting tank 3, the outlet is provided on one side of the collecting tank body 21 in the y-axis direction.

[0037] At the same time, bamboo sap is mostly extracted on-site in bamboo forests, so there is often a lot of dust, sand, flying insects, etc. in the production environment. Therefore, it is preferred to install a filter 24 at the opening of the groove cavity 22 by plugging or snapping, so as to prevent impurities from entering the bamboo sap collection groove 2 and contaminating the bamboo sap.

[0038] Reference Figure 4 As shown, it is more preferred that the groove cavity 22 forms an opening 23 on the surface of the collection tank body 21. The opening 23 is formed by a pair of inwardly contracted inclined surfaces and side panels at both ends. From the cross section, the opening 23 is trumpet-shaped. The groove cavity 22 has a pair of vertical side walls, so that the width of the groove cavity 22 is the same at all places, but the width of the top of the groove cavity 22 is greater than the width of the bottom of the opening 23, that is, the bottom of the opening 23 partially blocks the groove cavity 22, and a filter 24 is installed at the connection between the opening 23 and the groove cavity 22. With this structure, the pair of inwardly contracted inclined surfaces of the opening 23 can guide the dripping bamboo sap into the groove cavity 22, while dust, sand, flying insects, etc. are not easy to enter the groove cavity 22. On the one hand, it can ensure that the bamboo sap entering the bamboo sap collection tank 3 is clean, and on the other hand, it is convenient to clean the bamboo sap collection tank 2, and it only needs to remove the possible siltation on the inclined surface of the opening 23.

[0039] Combination Figure 1 , Figure 2 and Figure 3As a preferred embodiment, the bamboo sap collecting tank 2 is detachably mounted on the side of the lower pressing plate 12 through the adjusting unit 4. According to different bamboo sap extraction processes, the length of the end of the bamboo piece 7 extending outside the lower pressing plate 12 is also different. The adjusting unit 4 is provided to flexibly adapt to a variety of extraction processes.

[0040] Specifically, the adjustment unit 4 includes a support plate 41 detachably mounted on the side of the lower pressing plate 12 by means of screw connection, a plurality of guide grooves 42 (for example, six in this embodiment) provided on the support plate 41 along the x-axis direction, an adjustment screw 43 inserted in the guide groove 42, and a fastening nut 44 matched with the adjustment screw 43, one end of the adjustment screw 43 is fixedly connected to the bottom surface of the bamboo sap collecting groove 2 by welding. Moving the bamboo sap collecting groove 2 along the guide groove 42 (same as the x-axis direction) can change the distance between the bamboo sap collecting groove 2 and the side of the lower pressing plate 12, so as to adapt to different extension lengths of the bamboo pieces 7, so that the bamboo sap collecting groove 2 is always located below the end of the bamboo pieces 7, and screwing the fastening nut 44 can fix the position of the bamboo sap collecting groove 2.

[0041] Reference Figure 5 As shown, the bamboo sap collecting tank 3 connected to the bamboo sap collecting tank 2 can be an ordinary tank body. Preferably, the bamboo sap collecting tank 3 includes a tank body 31, an inner liner 32 accommodated in the tank body 31, a tank cover 33, and a movable pulley 34 installed at the bottom of the tank body 31. The inner bottom surface of the tank body 31 has a heating structure (not shown in the figure). The tank cover 33 is paired with the inner liner 32 and can be sealed. The tank cover 33 has a connecting hole connected to the pipeline and is equipped with an exhaust valve 35. The connecting hole is equipped with a sealing plug (not shown in the figure). The bamboo sap flows from the pipeline to the inner liner 32 under the action of gravity. The heating structure in the tank body 31 can be an electric heating coil in the prior art, or other stoves, as long as it can heat the inner liner 32. By setting up the heating structure, the bamboo sap precipitated from the bamboo pieces 7 can be directly heated to 83°C in the bamboo sap collecting tank 3 and maintained for 10 minutes to complete low-temperature sterilization (the bamboo sap after the above low-temperature sterilization treatment can be stored for 1 month at room temperature without deterioration). Then, since the inner tank 32 and the tank cover 33 can be used as a sealed liquid storage container, the bamboo sap can be stored in the inner tank 32.

[0042] Those skilled in the art know that a channel suitable for installing a liquid level meter can be optionally provided on the tank cover 33 to place the liquid level meter, so as to determine the amount of bamboo sap collected in the inner tank 32, and transfer the inner tank 32 for separate storage after it is full or nearly full. The channel is also equipped with a sealing plug to ensure that the inner tank 32 can be used as a sealed liquid storage container.

[0043] Combination Figure 1 , Figure 2 And refer to Figure 6 and Figure 7Generally, a loading limit 5 is provided on the unloading side of the lower pressing plate 12 to limit the placement position of the bamboo pieces 7 in the x-axis direction. In this embodiment, a loading limit 5 is provided on the collecting trough body 21 on the unloading side of the lower pressing plate 12 by flipping. The loading limit 5 includes a limit baffle 51 provided along the y-axis direction, a pivot rod 52 formed by bending downward and extending from both ends of the limit baffle 51, a pivot shaft 53 welded on the inner side of the pivot rod 52, and a limit shaft 54 ​​fixedly provided at the end of the pivot shaft 53, and the diameter of the limit shaft 54 ​​is larger than the pivot shaft 53. At the same time, a backing plate 55 is integrally provided on the side of the collecting trough body 21 away from the lower pressing plate 12, and T-slots 56 cooperating with the pivot shaft 53 and the limit shaft 54 ​​are provided on the two end surfaces of the collecting trough body 21, and the T-slots 56 are provided along the z-axis direction.

[0044] By means of the above structure, the limit baffle 51 is lifted until the top of the pivot shaft 53 abuts against the top of the T-shaped slot 56, and then turned outward to make the limit baffle 51 abut against the back of the collecting tank body 21. After the limit baffle 51 is dropped, the pivot shaft 53 abuts against the bottom of the T-shaped slot 56, so that the limit baffle 51 does not affect the outflow of bamboo juice from the end surface of the bamboo piece 7. The limit baffle 51 is lifted again until the top of the pivot shaft 53 abuts against the top of the T-shaped slot 56, and then turned inward to make the limit baffle 51 vertically arranged. After the limit baffle 51 is dropped, the surface of the collecting tank body 21 supports the limit baffle 51, and the front of the backing plate 55 limits the tendency of the limit baffle 51 to flip outward, so that the limit baffle 51 can limit the placement position of the bamboo piece 7, so as to control the extension length of the bamboo piece 7. Furthermore, the loading limiter 5 is installed on the bamboo sap collecting trough 2 so that the two can move synchronously, ensuring that the bamboo sap collecting trough 2 is always below the end of the bamboo piece 7.

[0045] As a preferred embodiment, the limit baffle 51 includes a shift rod, a pair of L-shaped connecting rods integrally arranged on the shift rod, and a support plate integrally connected to the extended ends of the pair of L-shaped connecting rods, and the support plate forms the actual limit working surface of the limit baffle 51. A set of limit structures is formed by the pair of L-shaped connecting rods and the support plate. In fact, there can be multiple sets of limit structures on the limit baffle 51. With the above structure, the deadweight of the loading limit 5 can be reduced, making the device easy to transfer and transport, and also reducing the labor intensity required to flip the loading limit 5.

[0046] Reference Figure 7 As shown, this embodiment provides another detachable structure of the loading stop 5. The difference from the structure of the loading stop 5 mentioned above is that a clamping groove 57 is provided at the position corresponding to the collecting tank body 21 and the limit baffle 51, while the limit baffle 51 only has a pair of pivot rods 52 and a stop rod. When loading, the limit baffle 51 is placed in the clamping groove 57 and fixed; after loading, the loading stop 5 is removed.

[0047] Of course, the loading limiter 5 can also be detachably or non-detachably installed on the collecting tank body 21 in other feasible ways.

[0048] In some embodiments, the bamboo sap extraction device further includes a lower pressing plate limiter 6, which includes a plurality of thickness gauges arranged on the surface of the lower pressing plate 12, the thickness gauges are arranged along the x-axis direction, and the plurality of thickness gauges are arranged at intervals along the y-axis direction. The thickness gauge is fixedly connected to the surface of the lower pressing plate 12 by welding, or it can be simply placed on the surface of the lower pressing plate 12.

[0049] By setting the lower pressing plate limiter 6, on one hand, the end position of the descent of the upper pressing plate 13 can be limited so that the bamboo pieces 7 are uniformly compressed to the thickness set by the process; on the other hand, during the loading process, the position of the bamboo pieces in the y-axis direction can be limited so that the bamboo pieces 7 can be sent to the lower pressing plate 12 as straight as possible.

[0050] The number of thickness gauges can be set as needed, for example, only a pair of thickness gauges are set at the proximal part of the lower pressing plate 12, or four thickness gauges are set at equal intervals in the width direction (y-axis direction) of the lower pressing plate 12. Alternatively, as in the solution provided in this embodiment, two adjacent thickness gauges form a group, and a group of thickness gauges defines the placement position of a bamboo piece 7. The thickness of the thickness gauge is designed as needed, and generally speaking, the thickness is 5-9 mm.

[0051] The working principle of the bamboo sap extraction device of this embodiment is as follows:

[0052] First, open the lower pressing plate 12 and the upper pressing plate 13 to preheat them to the temperature set by the process, adjust the distance between the bamboo sap collecting tank 2 and the side of the lower pressing plate 12, flip the limit baffle 51 until it is set vertically and blocked by the backing plate 55, and connect the bamboo sap collecting tank 2 and the bamboo sap collecting tank 3;

[0053] Then, the bamboo piece 7 is placed on the lower pressing plate 12 from the feeding side along the x-axis direction. When loading, the arc concave surface of the bamboo piece 7 is downward and along the position defined by the lower pressing plate limiter 6 until the end of the bamboo piece 7 abuts against the limiting surface of the limiting baffle 51.

[0054] After that, after all the bamboo pieces 7 are loaded, the limit baffle 51 is turned over again so that it no longer contacts the end surface of the bamboo piece 7;

[0055] Then, the upper pressing plate 13 is lowered and pressure is applied to the bamboo pieces 7 until the upper pressing plate 13 contacts the lower pressing plate limiter 6. As the pressure is maintained, bamboo juice is precipitated from both ends of the bamboo pieces 7. The bamboo juice drips into the bamboo juice collecting tank 2 and converges toward the outlet 24 through the inclined surface of the bottom surface. Then, the bamboo juice flows into the inner tank 32 of the bamboo juice collecting tank 3 through the pipeline, and the bamboo juice is heated at the same time.

[0056] Finally, the pressure is released to end the bamboo sap extraction process, and the inner container 32 is sealed and transported for storage.

[0057] Bamboo sap is extracted from bamboo slices cut from fresh round bamboo as raw materials, so the actual working place of the bamboo sap extraction device is the bamboo felling site. In some cases, it is also necessary to operate to other bamboo forests for work. To this end, the structure of the bamboo sap extraction device should be relatively compact to adapt to the work in the bamboo forest. At the same time, each part should be able to be disassembled for relatively frequent transportation. The bamboo sap extraction device of this embodiment is improved based on the flat plate press of the prior art, and adopts a double cylinder structure, so as to ensure that the lower pressure plate 12 is evenly compressed everywhere, and the total weight of the device can be reduced, making the structure of the device compact. Furthermore, the bamboo sap collection tank 2 and the loading limiter 5 are detachably assembled on the frame 11, and the bamboo sap collection tank 3 is also independent of the main body and can be disassembled so as to facilitate independent transportation.

[0058] In some other embodiments, reference Fig. 9 As shown, the bamboo sap extraction device further includes a plurality of (e.g., 2-3) pressing plate layers 15, and a synchronous closing unit (not shown in the figure) adapted to synchronously close or open the upper pressing plate 13 and the plurality of pressing plate layers 15 under the drive of the power unit 14. In other words, as the main component of the bamboo sap extraction device, the flat plate press 1 is a multi-layer press, and the pressing plate layer 15 has the same structure as the lower pressing plate 12.

[0059] The above description is intended to be illustrative and not limiting.
