[0058] The technical solutions of the embodiments of the present application will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present application, not all of them. All other embodiments obtained by ordinary technicians in this field without creative work based on the embodiments in the embodiments of the present application are within the scope of protection of the embodiments of the present application.

In addition, the terms "first", "second", and "third" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0060] In the description of the embodiments of the present application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a replaceable connection, or an integral connection, it can be a mechanical connection, it can be an electrical connection, it can be a direct connection, it can be indirectly connected through an intermediate medium, and it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the embodiments of the present application can be understood according to specific circumstances.

[0061] The embodiment of the present application discloses an integrated production line for lotus seed pre-treatment.

[0062] See also Figure 1 to Figure 2 An embodiment of the lotus seed pre-treatment integrated production line provided in the embodiments of the present application includes:

[0063] A hot water supply device 9, a primary immersion device 1, a undressing device 2, a primary separation device 3, a secondary immersion device 4, an edge opening device 5 and a secondary separation device 6; the primary immersion device 1 comprises a plurality of immersion barrels 11; the feed port of each immersion barrel 11 is respectively connected and communicated with the feed device; the hot water supply device 9 is respectively connected and communicated with the hot water inlet of each immersion barrel 11; the feed port of the undressing device 2 is respectively connected and communicated with the discharge port of each immersion barrel 11; the feed port of the primary separation device 3 is connected and communicated with the discharge port of the undressing device 2; the discharge port of the primary separation device 3 is connected and communicated with the feed port of the edge opening device 5; the discharge port of the edge opening device 5 is connected and communicated with the feed port of the secondary separation device 6.

[0064] Specifically, the feeding device can adopt a bucket elevator to transport and supply the lotus seeds to be soaked to the soaking barrel 11. Of course, the feeding can also be realized by pumping, and there is no specific limitation. In this embodiment, a multi-soaking barrel 11 design is adopted, so that one or more barrels can be soaked pending, and another part of the soaking barrels 11 can be continuously supplied. For example, at the beginning, the feeding device can add raw materials to all soaking barrels 11 at the same time, and the hot water supply device 9 also adds the required soaking hot water to all soaking barrels 11 to start soaking. When the soaking time is up, open one or more of the soaking barrels 11 discharge ports, and the soaked materials are connected to the water and transported into the undressing device 2 to complete the undressing, and the soaking barrel 11 that has transported the materials can be replenished with materials and hot water to continue the soaking operation. The soaking materials in the other part of the soaking barrels 11 can continue to be used pending, because the time required for undressing is often shorter than that for soaking, therefore, when the undressing is completed, the discharge ports of the other part of the soaking barrels 11 can be opened to continue feeding the soaked materials to the undressing device 2. Thereby, continuous feeding operation is achieved and efficiency is improved. Moreover, the design of multiple soaking barrels 11 can also avoid the situation where a single soaking barrel 11 is damaged and has to be shut down for maintenance, reduce accident risks, and make production and processing more stable. The feed port, discharge port and hot water inlet of each soaking barrel 11 can be independently connected to an electronic control valve to achieve selective feeding and transportation of materials, thereby improving the convenience of control. The feed ports of multiple soaking barrels 11 can be connected to the same feed pipe to receive materials. Taking a bucket elevator as an example, the conveyed materials can be conveyed from a low position to a high position. For example, the materials are lifted from a low position and then conveyed to each soaking barrel 11. Compared with the traditional method of conveying by a suction pump, it is more energy-saving and consumption-reducing.

[0065] As can be seen from the above technical scheme, the present application realizes continuous operation between lotus seed soaking, undressing, lotus skin separation, edge opening and lotus core separation processes by connecting hot water supply device 9, primary soaking device 1, undressing device 2, primary separation device 3, secondary soaking device 4, edge opening device 5 and secondary separation device 6 in series. The integrated operation of lotus seed pre-treatment process is realized, the material transfer process is reduced, the production efficiency is improved, the floor space is saved, and the labor intensity is reduced. Moreover, the primary soaking device 1 adopts a multi-immersion barrel 11 design, which can realize multi-barrel soaking, ensure the continuous supply of lotus seeds after soaking, and make the overall processing process stable and continuous. The present application scheme is not only limited to the processing and use of lotus seeds, but also can be used for materials that need to be processed by the same or substantially similar processing means as lotus seeds, without specific restrictions.

[0066] The above is the first embodiment of the integrated production line for pre-treatment of lotus seeds provided in the embodiment of the present application. The following is the second embodiment of the integrated production line for pre-treatment of lotus seeds provided in the embodiment of the present application. For details, please refer to Figures 1 to 11 .

[0067] The integrated lotus seed pre-treatment production line comprises: a hot water supply device 9, a primary soaking device 1, a undressing device 2, a primary separation device 3, a secondary soaking device 4, an edge opening device 5 and a secondary separation device 6; the primary soaking device 1 comprises a plurality of soaking barrels 11; the feed port of each soaking barrel 11 is respectively connected to the feed device; the hot water supply device 9 is respectively connected to the hot water inlet of each soaking barrel 11; the feed port of the undressing device 2 is respectively connected to the discharge port of each soaking barrel 11; the feed port of the primary separation device 3 is connected to the discharge port of the undressing device 2; the discharge port of the primary separation device 3 is connected to the feed port of the edge opening device 5; the discharge port of the edge opening device 5 is connected to the feed port of the secondary separation device 6.

[0068] Furthermore, as for the one-time soaking device 1, the one-time soaking device 1 may further include a fixed frame 12; a plurality of mounting grids are arranged in the fixed frame 12; and each soaking bucket 11 is mounted in the mounting grid one by one. Thus, the plurality of soaking buckets 11 can be mounted in one piece, and the structure is more compact.

[0069] Furthermore, a plurality of fixed beams 121 are arranged in the fixed frame 12; the plurality of fixed beams 121 are staggered to divide the fixed frame 12 into a plurality of installation grids. The fixed beams 121 can be welded and fixed in the fixed frame 12, staggered to form a grid structure, and then divide the fixed frame into a plurality of installation grids. When in use, not all installation grids are necessarily used, and can be determined according to the number of soaking barrels 11 actually needed, and there is no specific limitation.

[0070] Further, in terms of the installation and fixation of the soaking bucket 11, a plurality of connecting lugs 112 are welded on the outer peripheral wall of the soaking bucket 11; the plurality of connecting lugs 112 are respectively connected to the fixing beams 121. The specific structure of the connecting lugs 112 is not limited, and they can be connected and fixed to the fixing beams 121 by fasteners such as bolts.

[0071] Furthermore, if Figure 3 As shown, the number of soaking barrels 11 can be four, and the four soaking barrels 11 are distributed in a square array. Those skilled in the art can adjust the number of soaking barrels 11 according to actual needs, and there is no specific limitation.

[0072] Furthermore, if Figure 4 As shown, the one-time soaking device 1 may further include an elevated platform 13; a mounting hole for mounting the fixed frame 12 is provided on the top of the elevated platform 13. The one-time soaking device 1 may be elevated to a certain height by providing the elevated platform 13, so as to facilitate the upper and lower distribution with the undressing device 2, and save a certain amount of installation space. The structure of the elevated platform 13 may include a support plate and a plurality of pillars mounted on the bottom of the support plate, and is not specifically limited.

[0073] Furthermore, the soaking barrel 11 may include a barrel body 111 and a stirrer, and the stirrer is installed on the barrel body 111. The stirrer can accelerate the soaking, improve the soaking efficiency, and make the material contact with the hot water more fully.

[0074] Furthermore, the barrel body 111 includes a cylindrical barrel portion and an inverted conical barrel portion; the bottom of the cylindrical barrel portion is fixedly connected to the top of the inverted conical barrel portion. The cylindrical barrel portion and the inverted conical barrel portion can be connected as one piece, and there is no specific limitation. The inverted conical barrel portion can better realize centralized discharge. The feed port of the barrel body 111 can be set at the top position of itself, and the discharge port can be set at the bottom position of itself.

[0075] Furthermore, if Figure 5 As shown, the barrel body 111 is also provided with a spray port and an alkaline water inlet. The spray port can be connected to a spray water pipeline for cleaning the inside of the barrel body 111. The alkaline water inlet can be connected to an alkaline water pipeline for replenishing alkaline water required for soaking. The hot water inlet can be connected to a hot water supply device 9 through a hot water pipeline. Flow meters 14 can be respectively provided on the hot water pipeline and the alkaline water pipeline to accurately control the amount of water added, and there is no specific limitation.

[0076] Furthermore, the stirrer structure may include a stirring motor 113, a rotating shaft 114, and stirring blades 115; the stirring motor 113 is vertically installed on the top of the barrel body 111; the rotating shaft 114 extends into the barrel body 111 and is synchronously rotated and connected with the output shaft of the stirring motor 113; the stirring blades 115 are installed on the rotating shaft 114. The stirring motor 113 can be inverted on the top of the soaking barrel 11 through the motor frame, and the stirring blades 115 can also be multiple, distributed at upper and lower intervals to improve the stirring effect.

[0077] Furthermore, if Figures 9 to 11 As shown, with regard to the hot water supply device 9, the hot water supply device 9 may include a container 91, a steam pipe 92, a temperature sensor 95, a temperature controller 96, a hot water pipe 93 and a cold water pipe 94; one end of the steam pipe 92 is connected to the steam supply system, and the other end extends into the bottom of the container 91; a steam electric valve 921 is provided on the steam pipe 92; the temperature sensor 95 is installed on the container 91, and is used to detect the water temperature in the container 91; the temperature controller 96 is electrically connected to the temperature sensor 95 and the steam electric valve 921 respectively; the hot water pipe 93 is installed at the water outlet of the container 91; the cold water pipe 94 is installed at the water replenishment port of the container 91; and an emptying port 911 is also provided on the container 91.

[0078] Specifically, steam is transported into the container 91 through the steam pipe 92, so that the steam contacts and exchanges heat with the water in the container 91, thereby achieving heating. This heating method, due to the impact force generated when the steam is released, will have a certain stirring effect on the water, so that the contact between water and steam is more sufficient, and the heating efficiency is better than the heating method with the same number of electric heating rods. At the same time, the steam source of steam heating can be obtained from the production workshop, which can also save energy consumption and reduce costs to a certain extent. In addition, by setting a steam electric valve 921, a temperature controller 96 and a temperature sensor 95, it is possible to monitor the water temperature in the container 91, thereby intelligently adjusting the amount of steam released by the steam pipe 92, achieving more accurate control of the water temperature, and ensuring a stable supply of hot water. In general, the hot water supply device 9 has the beneficial effects of efficient heating and accurate temperature control. In this embodiment, the steam supply system can be a steam preparation device, which is not specifically limited.

[0079] Further, with respect to the structure of the container 91, Fig.10 As shown, the container 91 can be a square box structure, such as a conventional insulated water tank, or a round barrel structure, etc., without limitation.

[0080] Furthermore, a check valve 925 can be installed on the steam pipe 92 to prevent steam from flowing back and affecting the heating efficiency. The check valve 925 can be arranged on the pipe section between the steam electric valve 921 and the installation opening of the steam pipe 92 installed in the container 91, and there is no specific limitation.

[0081] Furthermore, in order to cope with unexpected situations of the steam electric valve 921, that is, the situation where the electric steam valve cannot be adjusted, a first manual valve 922 can be installed in series on both sides of the steam electric valve 921 in the steam pipe 92. The first manual valve 922 can be used for adjustment and control, and this situation can be reflected by the temperature controller 96. For example, when the temperature controller 96 detects that the water temperature in the container 91 is not within the normal set temperature range, such as not within the range of 80℃±5℃ for a certain period of time, it can control the buzzer and other alarms to send out an alarm to remind the staff to check or manually control.

[0082] Furthermore, in order to deal with the abnormal situation of blockage of the steam electric valve 921, a branch pipe can be connected in parallel to the pipe section of the steam pipe 92 where the steam electric valve 921 is installed, and a second manual valve 923 is installed on the branch pipe. When the steam electric valve 921 or the first manual valve 922 is blocked, the second manual valve 923 of the branch can be started to ensure the normal supply of steam.

[0083] Furthermore, in order to improve the diversity and security of control, a third manual valve 924 may be installed near one end of the steam pipe 92 .

[0084] Furthermore, a muffler 97 is included; the muffler 97 is installed at the other end of the steam pipe 92. The purpose of setting the muffler 97 is to reduce the noise when the steam is released and reduce noise pollution. The muffler 97 can be a conventional steam muffler 97, and there is no specific limitation.

[0085] Furthermore, the muffler 97 is 40 mm to 80 mm away from the inner bottom surface of the container 91. The muffler 97 needs to maintain a certain distance from the inner bottom surface of the container 91 to prevent the muffler 97 from vibrating and colliding with the bottom surface of the container 91 and being damaged. Too small a distance will still cause the muffler 97 to have a risk of contact and collision with the bottom surface of the container 91, while too large a distance will affect the heating efficiency. For example, in this embodiment, it is preferably 40 mm to 80 mm away from the inner bottom surface of the container 91. Those skilled in the art can make appropriate changes based on this, and there is no specific limitation.

[0086] Furthermore, the cold water pipe 94 is connected to a float valve 941. The opening and closing of the cooling pipe can be controlled by the float valve 941. When the internal liquid level gradually decreases, the height of the float valve 941 is also continuously decreasing, so that the cold water pipe 94 is opened by the movement of the crank to replenish water. When replenishing water, the internal page will also rise accordingly, and at this time the float valve 941 is also rising, and then the crank is gradually reset to close the cold water pipe 94. Of course, the present application can also be to set an electronic liquid level gauge inside, and set an electric valve on the cold water pipe 94, monitor the information of the electronic liquid level gauge through a controller, and then control the electric valve on the cold water pipe 94 to achieve automatic water replenishment. Those skilled in the art can make appropriate changes based on this, and there is no specific limitation.

[0087] Furthermore, the steam pipe 92 is inclined at the pipe section extending into the container 91. In this way, the released steam can have a force to impact the water in the horizontal direction, thereby better stirring the water and making the contact between the water and the steam more sufficient. Specifically, the inclination angle can be preferably 45°, without limitation. Of course, in the present application, an agitator such as the soaking barrel 11 can also be added to accelerate the stirring of the water inside the container 91 to improve the heating efficiency.

[0088] Furthermore, for the convenience of installation, the temperature sensor 95 can be specifically a temperature sensing probe; the temperature sensing probe is inserted into the container 91, and the temperature sensing end extends into the interior of the container 91, and there is no specific limitation.

[0089] Furthermore, if Fig.11 , the drain port 911 is opened at the top of the container 91, and a metal condensation hood 912 is provided in the area directly above; the side of the condensation hood 912 is tilted downward. In the case of excess steam, the excess steam will still be discharged from the drain port 911. At this time, by providing the condensation hood 912 with tilted side, it can come into contact with the discharged steam, so that the cooled condensation is refluxed into the container 91 along the tilted side, so as to reduce the steam loss. Of course, the drain port 911 can also be connected to a steam recovery pipe for recovering excess steam.

[0090] In the present application, in order to further improve the heating efficiency, electric heating can be combined, for example, an electric heating tube 46 is provided in the container 91 to assist heating and further improve the heating efficiency.

[0091] Further, with respect to the undressing device 2, its structure may be as follows: Figure 6As shown, it includes a main body, two spiral agitators 21 and a rotating motor (not shown in the figure). A stripping chamber can be set in the main body, and the two spiral agitators 21 are arranged side by side in the stripping chamber. While the spiral agitators 21 are used to realize transportation, stripping is also realized by friction between lotus seeds and lotus seeds, lotus seeds and the stripping chamber wall, and lotus seeds and spiral agitators 21. A plurality of drainage holes can be provided at the bottom of the chamber wall, so that when the soaking barrel 11 is fed, the lotus seeds can be directly fed with water, thereby improving the continuity of the overall pre-treatment process. Of course, a single spiral dragon structure design can also be adopted, and those skilled in the art can make appropriate changes on this basis, without specific limitation.

[0092] Furthermore, if Figure 7 as well as Figure 8 As shown, the secondary immersion device 4 includes a trough body 41, a conveying mechanism, a heating mechanism and a bubbling mechanism; the conveying mechanism is provided with a first conveying section and a second conveying section; the first conveying section is horizontally erected in the trough body 41 along the length direction of the trough body 41; the input end of the second conveying section is connected to the output end of the first conveying end, and the output end of the second conveying section extends upwardly out of the trough body 41 along the material feeding direction of the first conveying section; the heating mechanism is installed in the trough body 41, and is used to heat the water in the trough body 41; the bubbling mechanism is used to generate bubbles inside the trough body 41.

[0093] Specifically, the tank body 41 can be a long trough structure to ensure a certain conveying distance, improve the secondary immersion effect, and also improve the cleaning effect. The secondary immersion can make the lotus seeds further soaked, which is conducive to the subsequent edge opening and coring process, and the cleaning can wash the lotus seeds in the first immersion with residual alkaline water and the residual lotus seed skin after the first separation. The conveying mechanism adopts a segmented design, which can meet the requirements that the material can be transported upward and tilted out of the tank body 41 after being transported in the tank body 41. In order to cooperate with the inclined setting of the second conveying section, the tank body 41 can also be provided with an inclined platform at this location, so that a certain installation space can be reserved between this position and the external ground to facilitate the installation of related components, and there is no specific restriction. By setting a heating mechanism, the inside of the tank body 41 can be heated to control it at a certain temperature, so as to better perform secondary immersion and cleaning.
