Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of lotus root powder can production, in particular to a lotus root powder can production line and production method. BACKGROUND

[0002] Lotus root powder is a traditional nourishing food with high nutritional value and good medicinal effect. At present, the processing of dried lotus root powder is basically as follows: fresh lotus root is cleaned and peeled, crushed, separated by centrifugation, washed and pulped, dried and ground. In the whole powder production process, crushing, residue water centrifugal separation and lotus root residue washing directly affect the yield and quality of the later lotus root powder. The steps of directly obtaining lotus root powder mainly come from residue water centrifugal separation and lotus root residue washing. After the pulping water obtained by residue water centrifugal separation and lotus root residue washing is placed and filtered for multiple times, drying and grinding operations can be performed. The whole production line has many devices, the process is complex and tedious, a large amount of power is required, and the powder production rate is low.

[0003] In view of this situation, the patent with publication number CN 107307344 A discloses a continuous lotus root powder production line. By combining multiple devices and adopting a flow line method, the labor intensity is reduced, time and labor are saved, the work efficiency is high, the resources are reasonably utilized, and the production cost is reduced. However, this production line is a conventional processing method for dried lotus root powder. Since the dried lotus root powder is further ground, the particle size requirement of the lotus root powder particles obtained by residue water centrifugal separation and lotus root residue washing is relatively low. If fresh lotus root is directly processed into instant lotus root powder cans by using the above-mentioned part of the processing method of dried lotus root powder, there will be problems of unrefined taste and non-transparent color of the finished lotus root powder. If the dried lotus root powder is washed and gelatinized into lotus root powder, and then filled, the production cost of the filled lotus root powder will be much higher than that of the dried lotus root powder. If the number of times of placing and filtering the pulping water obtained by residue water centrifugal separation and lotus root residue washing is increased, the production cost will undoubtedly be increased. At the same time, in the process of continuously treating the placed pulping water and filtering, the particulate matter in the pulping water is easy to precipitate on the equipment, which not only causes waste, but also is difficult to handle in the later stage. In addition, the more times the lotus root powder slurry is placed and filtered, the more opportunities the anthocyanins and polyphenol oxidase contained in the lotus root powder slurry have to contact with oxygen in the air. Oxygen will cause the lotus root powder slurry to be oxidized and darkened, ultimately resulting in dark and non-transparent color of the finished lotus root powder. SUMMARY

[0004] In order to overcome one of the deficiencies of the prior art, the purpose of the present application is to provide a lotus root powder can production line and production method, which can effectively avoid the problems of unrefined taste and non-transparent color of instant lotus root powder, reduce the production cost, and improve the yield.

[0044] In order to make the purposes, technical solutions and advantages of the present application clearer, the present application is further described in detail below in combination with the drawings and examples. It should be understood that the specific examples described herein are only used to explain the present application and do not limit the present application.

[0045] Referring to Figures 1 to 8 The present application provides a taro powder can production line, which comprises a fresh taro powder production system 100, a multi-stage cyclone sorting device 200, a taro powder glueing device 300, a taro powder gelatinization device 400, a filling system and a high-temperature sterilization device 800. The fresh taro powder production system 100 is used to process fresh taro into taro slurry. The multi-stage cyclone sorting device 200 is used to perform multi-stage flotation on the taro slurry output by the fresh taro powder production system 100. The multi-stage cyclone sorting device 200 is provided with a qualified product output end and an unqualified product output end. The unqualified product output end is in communication with the fresh taro powder production system 100. The taro powder glueing device 300 is used to perform glueing treatment on the taro slurry discharged from the qualified product output end. The taro powder gelatinization device 400 is used to heat gelatinize the glued taro powder discharged from the taro powder glueing device 300. The filling system comprises a packaging box processing device 500, a filling device 600 and a capping device 700 arranged in sequence. The packaging box processing device 500 is used to provide and pretreat packaging boxes. The filling device 600 can receive the gelatinized taro powder discharged from the taro powder gelatinization device 400 and fill the gelatinized taro powder into the packaging boxes discharged from the packaging box processing device 500. The capping device 700 is used to cap and seal the packaging boxes output by the filling device 600. The high-temperature sterilization device 800 is used to high-temperature sterilize the packaging boxes capped by the capping device 700.

[0046] In the present application, the fresh lotus root powder production system 100 is actually a production device for processing fresh lotus root into lotus root slurry, and conventional processing equipment can be used, such as fresh lotus root cleaning and peeling equipment and fresh lotus root crushing and grinding device, and of course the production device of patent CN 107307344 A - a continuous lotus root powder production line without drying equipment can also be used. Of course, in an embodiment of the present application, the fresh lotus root powder production system 100 includes a fresh lotus root peeling device and a fresh lotus root crushing and grinding device connected in sequence, wherein the fresh lotus root peeling device can use the technical solutions of patent CN201510986831.5 - sweet potato peeling device or CN202122622038.0 - a rotary drum peeling machine, and the fresh lotus root crushing and grinding device can use the technical solutions of CN202320340985.7 - a crushing and pulping device or CN201711245573.0 - a starch pulping machine, which are not described in detail herein. In addition, a residue and water separation device can also be provided at the output end of the fresh lotus root crushing and grinding device, which can use a traditional rotary centrifugal cylinder structure, or the technical solutions of CN202310692065.6 - a centrifugal filter device for slurry and residue separation and a filtering method thereof, which are not described in detail herein. It should be noted that the residue separated by the residue and water separation device is treated according to the situation, for example, it is returned to the fresh lotus root crushing and grinding device for secondary crushing and grinding, or it is directly discharged outward, and the lotus root slurry separated by the residue and water separation device is directly pumped to the multi-stage cyclone sorting device 200 through the pipeline, which can reduce the contact time with air and avoid oxidation and discoloration by oxygen. In addition, the discharge port of the residue and water separation device is also connected with a slurry flushing and dewatering device, which is used to reduce the water content in the lotus root slurry, which is beneficial to the processing of the multi-stage cyclone sorting device 200. A small amount of pure water is generally added during the crushing process of fresh lotus root, so the water content in the lotus root slurry generally does not exceed the standard, and of course, in some embodiments, the discharge port of the residue and water separation device can also be directly connected with the multi-stage cyclone sorting device 200, which does not affect the production of the entire production line, and only needs to be drained before gluing.

[0047] The cover device 700 in the present application can adopt the technical solutions in CN201720311075.0 - A cover sealing machine capable of both screwing and pressing cover or CN201510787378.5 - A screwing and pressing two-in-one mechanical hand and its screwing and pressing method. The working environment of the multi-stage cyclone sorting device 200 in the present application needs to be in a relatively closed environment, which can reduce the oxidation of lotus root slurry caused by contact with air during the cyclone sorting process. The high-temperature sterilization device 800 in the present application is a conventional device. For example, after the packaging boxes are collected and stored, they are sent to a dedicated high-temperature steam sterilization room for high-temperature sterilization. Alternatively, the traditional conveying belt can be directly sent into the high-temperature steam cabin for high-temperature sterilization. In addition, the high-temperature sterilization device 800 in the present application can also perform secondary heating on the gelatinized lotus root powder in the packaging box, which can ensure that the lotus root powder in the packaging box is completely gelatinized.

[0048] The lotus root powder canning production line uses the fresh lotus root powder production system 100 to process fresh lotus root into lotus root slurry. The multi-stage cyclone sorting device 200 is used to perform multi-stage flotation on the lotus root slurry output by the fresh lotus root powder production system 100. This design can effectively classify and filter the lotus root slurry, ensure the particle size of the lotus root powder in the later stage, improve the taste of the food, and at the same time, the unqualified lotus root powder is sent to the fresh lotus root powder production system 100 for secondary processing, which improves the utilization rate of raw materials and ensures the quality of the lotus root powder. The lotus root powder glue making device 300 is used to add cold water to the lotus root wet particles discharged from the qualified product output end for glue making treatment. The rotary shearing force of stirring makes the lotus root slurry gelatinize, avoids precipitation in the subsequent conveying and processing process, reduces the loss, and ensures the yield of the product. The lotus root gelatinization device 400, the filling device 600, and the cover sealing device 700 are used to sequentially perform heating gelatinization, filling, and cover sealing operations on the gelatinized lotus root powder, realize automatic production, and ensure the production efficiency. The high-temperature sterilization device 800 is used to perform high-temperature sterilization on the packaged boxes before they are shipped, which improves the quality of the products.

[0049] Referring to Figures 1 to 2In an embodiment of the present application, in order to improve the taste and delicacy of the finished sago product, the multi-stage cyclone sorting device 200 comprises a first-stage cyclone 210, a second-stage cyclone 220, and a third-stage cyclone 230. The inlet end of the first-stage cyclone 210 is in communication with the output end of the fresh sago production system 100. The outlet end of the first-stage cyclone 210 is in communication with the unqualified product output end. The overflow port of the first-stage cyclone 210 is in communication with the inlet end of the second-stage cyclone 220 through a communication pipe 240. The outlet end of the second-stage cyclone 220 is in one-way communication with the inlet end of the first-stage cyclone 210. The overflow port of the second-stage cyclone 220 is in communication with the inlet end of the third-stage cyclone 230 through a communication pipe 240. The overflow port of the third-stage cyclone 230 is in communication with the qualified product output end. The outlet end of the third-stage cyclone 230 is in one-way communication with the inlet end of the second-stage cyclone 220. The communication pipe 240 is provided with a cyclone pressurizing mechanism 250. The cyclone pressurizing mechanism 250 can perform cyclone pressurization on the fluid flowing through the communication pipe 240. The inner wall of one end of the communication pipe 240 is provided with a plurality of spiral flow guide grooves 241. The bottom of the second-stage cyclone 220 and the third-stage cyclone 230 is provided with a normally closed discharge valve 260.

[0050] The inlet of the primary cyclone 210 is communicated with the inlet end of the slag water separation device, so that the large particles of lotus root powder can re-enter the slag water separation device for filtration, and part of the lotus root powder slurry can be recycled; the purpose of the three-stage cyclone separation is to ensure that the solid particles in the lotus root powder slurry flowing out of the overflow port of the third-stage cyclone 230 meet the particle size requirements, avoiding the need for secondary grinding after drying the lotus root powder slurry in the traditional process, and then rehydrating and brewing, simplifying the process and reducing production costs. In addition, as the lotus root powder slurry passes through each stage of cyclone separation, the particle size of the solid particles in the overflowed lotus root powder slurry gradually becomes the same, so that the separation capacity of the later stage is improved. The main function of the cyclone pressurizing mechanism 250 is to facilitate the increase of the inflow speed of the lotus root powder slurry flowing into the next stage of cyclone through the communication pipe 240. In the centrifugal field formed inside the cyclone, the centrifugal force on a mass m is F=mv2 / r; where m represents the mass of the particle, v represents the tangential velocity, and r represents the radius of rotation. Therefore, under the condition of increasing the inflow speed and keeping other structures of the cyclone unchanged, the centrifugal force received by the solid particles with relatively larger particle size is larger, so that the solid particles with similar particle sizes can be separated from the next stage of cyclone. In fact, in the normal processing process, the cyclone can be directly used in two stages, and the particle size of the solid particles in the lotus root powder slurry overflowed by the second-stage cyclone 220 and the third-stage cyclone 230 is already similar. Therefore, increasing the number of third-stage cyclones 230 will obviously increase the manufacturing cost. Therefore, in the actual processing process, the number of cyclones is selected according to the actual product demand.

[0051] In the above embodiment, the cyclone pressurizing mechanism 250 can be a conventional pressurizing pump structure, and the inner wall of one end of the communication pipe 240 is provided with a plurality of spiral guide grooves 241. The spiral guide grooves 241 are arranged to regularize the lotus root powder slurry discharged from the communication pipe 240 and reduce its turbulent flow. At the same time, the lotus root powder slurry discharged from the communication pipe 240 has a rotating force, which can better separate the lotus root powder slurry in the next stage of cyclone and speed up the efficiency of cyclone separation.

[0052] In the improved embodiment described above, the cyclone pressurizing mechanism 250 comprises a shell 251 and a screw rotating shaft 252 rotatably mounted in the shell 251, the part of the screw rotating shaft 252 in the shell 251 is arranged in a spiral manner and the rotating center forms an overflow passage, the upper end of the shell 251 is provided with an inlet pipe 253, the lower end of the shell 251 is communicated with an outlet pipe 254, and the two ends of the overflow passage are respectively communicated with the inlet pipe 253 and the outlet pipe 254; the outer ends of the inlet pipe 253 and the outlet pipe 254 are respectively communicated with the communication pipe 240, one end of the screw rotating shaft 252 penetrates through the shell 251, a driving motor 255 is arranged outside the shell 251, and the driving motor 255 is connected with the one end of the screw rotating shaft 252 penetrating through the shell 251. The screw rotating shaft 252 is actually designed as a hollow screw auger, and the two ends of the screw rotating shaft 252 are provided with concentric shaft structures, so that the screw rotating shaft 252 can be installed and rotated. The hollow screw auger can reduce the impact of the lotus root powder slurry discharged by the upper-stage cyclone on the screw rotating shaft 252, and the structure of the screw rotating shaft 252 can also reduce the influence on the flow rate of the lotus root powder slurry to a certain extent. In addition, the shell 251 is in a cylindrical shape, and the inlet pipe 253 and the outlet pipe 254 are tangent to the shell 251, which can reduce the influence on the flow rate of the lotus root powder slurry to the greatest extent. The inlet pipe 253 and the outlet pipe 254 can be connected with the communication pipe 240 through joints, or in some embodiments, the inlet pipe 253 and the outlet pipe 254 can be part of the communication pipe 240 and are directly screwed on the shell 251.

[0053] Referring to Figure 1 and 2 In an embodiment of the present application, in order to facilitate the later gluing, the lotus root powder slurry discharged by the three-stage cyclone 230 contains relatively large amount of water, and the water quality does not meet the requirements, and if the lotus root powder slurry is directly gelatinized, the quality of the finished lotus root powder will be inevitably affected. Therefore, the centrifugal draining device 900 is arranged between the three-stage cyclone 230 and the lotus root powder gluing device 300 in the multi-stage cyclone sorting device 200 in the present application, which can be a conventional centrifugal filter screen cylinder structure, and a rotatable scraper is arranged inside the centrifugal filter screen cylinder for scraping the lotus root wet particle groups adhered to the inner wall of the centrifugal filter screen cylinder, and then the lotus root wet particle groups are sent into the lotus root powder gluing device 300 for re-extraction and gluing. It should be noted that clean pure water can be added for flushing during the rotation, dehydration and draining of the centrifugal draining device 900 to improve the quality of the lotus root wet particle groups, which is selected according to the actual processing requirements. It should be noted that pure water can also be added in the above multi-stage cyclone process.

[0054] Referring to Figure 1 and Figure 4In an embodiment of the present application, the sago glueing device 300 comprises a kettle body 310 and a glueing mechanism 320 rotatably arranged in the kettle body 310, which can stir the sago slurry in the kettle body 310; the upper part of the kettle body 310 is provided with a feeding port 330 in communication with the qualified product output end, and the feeding port 330 can be opened and closed; the bottom of the kettle body 310 is provided with an outlet 340 which can be opened and closed, and the outlet 340 is in communication with the input end of the sago gelatinization device 400; the kettle body 310 is communicated with a cold water automatic adding mechanism 350 and a vacuum pumping mechanism 360; the bottom of the kettle body 310 is provided with a rotary viscosity tester 370.

[0055] The rotary viscosity tester 370 is a conventional device in the present application, and its main purpose is to facilitate the staff to check the viscosity of the sago slurry in the kettle body 310. The cold water added in the present application is actually cold boiled water, and its main purpose is to reduce the minerals in the filtered water and improve the taste of the sago later. At the same time, the cold boiled water is relatively easy to obtain, and the production cost is low, and the cost of the pure water after multi-stage filtration is low. In addition, the sago slurry also needs to maintain a certain temperature during glueing to improve the taste later. At the same time, the operation of glueing can make the sago slurry experience the three effects of extrusion, strong impact and pressure loss expansion, so that the material is refined again, that is, the starch branch in the sago slurry is broken under the high shearing force of the glueing mechanism 320, which is convenient for later gelatinization treatment and improves the taste of the product later.

[0056] It should be noted that the design of the vacuum pumping mechanism 360 is to avoid the oxidation of the sago slurry by the air in the kettle body 310 during glueing, so as to ensure the quality of the sago. The vacuum pumping mechanism 360 can be a conventional vacuum pump and the structure of the matched pipeline and pump body, such as the structure of patent CN201910774025.X-a vacuum pumping mechanism of a food processor, which is not described in detail in the present application.

In addition, the main purpose of the guide isolation sheet 480 is to reduce the flow speed of the steam in the heating space 450 and improve the heating efficiency. The auxiliary material adding mechanism 490 can be a conventional automatic feeding machine, for example, patent CN202322129655.6-Automatic feeding machine for food production; and the auxiliary materials are one or more of sugar, red dates and other food materials.

[0059] Referring to Figure 1 and Figure 6In the actual processing process, the gelatinized lotus root powder in the heating kettle 410 can be filled after spreading or airing, which is mainly to avoid too many bubbles in the gelatinized lotus root powder to affect the quality in the later period. In order to realize filling and facilitate storage in the later period, in an embodiment of the present application, the packaging box processing device 500 comprises a rack 510, a packaging box automatic unstacking mechanism 520, a conveying chain belt 530, a flushing mechanism 540 and a drying mechanism 550, the conveying chain belt 530 is rotatably installed on the rack 510, the packaging box automatic unstacking mechanism 520 is arranged on the corresponding area of the rack 510 located at the inlet end of the conveying chain belt 530, the flushing mechanism 540 and the drying mechanism 550 are arranged in sequence on the corresponding area of the rack 510 located at one end of the conveying chain belt 530. The rack 510 is provided with a turnover mechanism 560 for turning over the packaging box at one end of the output of the conveying chain belt 530.

[0060] In the above embodiment, the packaging box is stacked in reverse on the packaging box automatic unstacking mechanism 520, which is mainly to facilitate cleaning and hot air drying of the packaging box. The packaging box can be a conventional aluminum-plastic packaging box, or a conventional plastic or metal packaging box. In order to avoid water accumulation and facilitate flushing and drying of the packaging box, the conveying chain belt 530 in the present application is a mesh chain structure, such as the structure in patent CN201821869696.1 - A top roller chain conveyor type hanger, so that the packaging box can be directly washed upwards by the flushing mechanism 540 when it is reversed on the conveying chain belt 530. The flushing mechanism 540 in the present application is a conventional high-pressure spray head structure, and the conveying chain belt 530 located in the corresponding area of the flushing mechanism 540 can be provided with a top pressing cylinder for pressing and fixing the packaging box. The drying mechanism 550 is a structure that can blow hot air, which can actually be a hot air chamber, and the conveying chain belt 530 passes through the hot air chamber. The packaging box automatic unstacking mechanism 520 in the present application can be a conventional mechanical hand structure, or a stacking device, or the structure in patent CN202121303110.7 - A bowl dispensing mechanism or CN202222367900.2 - An automatic box dispensing device for meal boxes, which will not be described in detail by the present applicant.

[0061] Referring to Figure 7 and Figure 8In an embodiment of the present application, in order to simplify the structure, the turnover mechanism 560 comprises an arc-shaped guide pressing plate 561 and a receiving positioning seat 562. The arc-shaped guide pressing plate 561 is installed on the rack 510 and is concentrically arranged with the rotating center on the output end of the conveying chain belt 530. The output end of the arc-shaped guide pressing plate 561 is located below the output end of the conveying chain belt 530. Arc-shaped bearing guide rods 563 are arranged on both sides of the output end of the arc-shaped guide pressing plate 561. The two bearing guide rods 563 can cooperatively support the two sides of the packaging box. The two bearing guide rods 563 are eccentrically arranged with the rotating center on the output end of the conveying chain belt 530 and the lower ends gradually move away from the back of the output end of the conveying chain belt 530. The receiving positioning seat 562 is installed on the area of the rack 510 below the back of the conveying chain belt 530. The receiving positioning seat 562 can receive the packaging box output by the two bearing guide rods 563. The packaging box on the receiving positioning seat 562 can be conveyed to the filling device 600.

[0062] When the reversed packaging box is conveyed to the end of the arc-shaped guide pressing plate 561 together with the conveying chain belt 530, the packaging box is clamped between the conveying chain belt 530 and the arc-shaped guide pressing plate 561 due to the limiting effect of the arc-shaped guide pressing plate 561 and the conveying effect of the conveying chain belt 530 and can also move together with the conveying chain belt 530. Damping springs are arranged between the arc-shaped guide pressing plate 561 and the rack 510. When the packaging box is clamped and conveyed by the conveying chain belt 530 and the arc-shaped guide pressing plate 561, the packaging box is driven to the space between the conveying chain belt 530 and the bearing guide rod 563. At this time, the packaging box has almost completed the turnover. The packaging box is self-adjusted according to its own gravity and the overall weight is gradually transferred to the two bearing guide rods 563. Since the two bearing guide rods 563 are eccentrically arranged with the corresponding end of the conveying chain belt 530 and the lower end of the bearing guide rod 563 gradually moves away from the conveying chain belt 530, the packaging box gradually slides on the two bearing guide rods 563 due to gravity until it is received by the receiving positioning seat 562. The receiving positioning seat 562 can be a turning structure, such as a guide frame, to facilitate the turning of the packaging box and adapt to the input end of the filling device 600.

[0063] In order to facilitate the movement of the packaging box and the outer peripheral surface of the conveying chain belt 530, in the above-mentioned improved scheme, the two sides of the upper end of the arc-shaped guide pressing plate 561 are hingedly connected with the connecting plate 564 on the rack 510. The two sides of the lower end of the arc-shaped guide pressing plate 561 are connected with the rack 510 through a buffering mechanism. The buffering mechanism can be a conventional spring mechanism which can adapt to the following action of the packaging box and the conveying chain belt 530.

[0064] In the improved embodiment described above, in order to facilitate installation and achieve the damping effect, each of the buffering mechanisms comprises a mounting seat 565, a connecting column 566, and a damping spring 567. The mounting seat 565 is mounted on the rack 510. One end of the connecting column 566 is movably inserted into the mounting seat 565. The connecting column 566 is provided with a step. The damping spring 567 is movably sleeved on the connecting column 566 and connected to the step and the mounting seat 565 at both ends. The outer end of the connecting column 566 is connected to the lower end side of the arc-shaped guide pressing plate 561. The mounting seat 565 is provided with a insertion hole, the connecting column 566 is movably inserted into the insertion hole, and the damping spring 567 is fixedly installed between the step and the mounting seat 565. Of course, in some embodiments, the end of the connecting column 566 that is not connected to the arc-shaped guide pressing plate 561 can be locked and fixed on the other side of the mounting seat 565 by a nut.

[0065] In order to receive the packaging boxes discharged by the two carrying guide rods 563 and also to input the packaging boxes to the input end of the filling device 600, in an embodiment of the present application, the receiving positioning seat 562 comprises a seat body 568 and a pair of receiving rods 569 provided on the seat body 568. The seat body 568 is connected to the rack 510, and the pair of receiving rods 569 can receive the packaging boxes discharged by the two carrying guide rods 563. An elastic part 56a is provided between the receiving rod 569 and the seat body 568. The elastic part 56a can be deformed and reset. When the two receiving rods 569 jointly clamp the packaging box, the packaging box can bend the elastic part 56a. The elastic part 56a can be a spring structure or a rubber strip with a steel wire provided inside. The seat body 568 can be fixedly installed on the rack 510 by screws.

[0066] Referring to Figures 6 to 9 In an embodiment of the present application, in order to facilitate filling, the filling device 600 comprises a support 610, a secondary conveying belt 620 mounted on the support 610, and a lifting quantitative filling mechanism 630. The input end of the secondary conveying belt 620 is used to receive the packaging boxes output by the turnover mechanism 560. A pair of positioning clamping mechanisms 640 capable of cooperating with each other are provided on both sides of the secondary conveying belt 620. The lifting quantitative filling mechanism 630 is installed above the support 610 and directly above the region between the two positioning clamping mechanisms 640. One end of the secondary conveying belt 620 is communicated with the input end of the capping device 700. In the present application, the secondary conveying belt 620 is vertically arranged with the conveying chain belt 530, which facilitates the arrangement of the entire production line. The receiving positioning seat 562 in the above-mentioned embodiment is located at one end of the input of the secondary conveying belt 620.

[0067] Two positioning clamping mechanisms 640 are provided on both sides of the support 610, and the positioning clamping mechanisms 640 are a pair of telescopic cylinders arranged downward and positioning clamping blocks arranged at the telescopic ends of the telescopic cylinders. In this way, the two positioning clamping mechanisms 640 can clamp and stabilize the packaging boxes on the secondary conveying belt 620, facilitating positioning. Of course, in some embodiments, limiting guardrails can be arranged on both sides of the secondary conveying belt 620, and a servo motor can be used to drive the secondary conveying belt 620 to rotate. In this way, the limiting guardrails are used to adjust the control posture of the packaging boxes, and then the servo motor is used to rotate a certain number of turns each time so that each packaging box can be stopped right below the lifting quantitative filling mechanism 630 to cooperate with the lifting quantitative filling mechanism 630 for filling. In addition, the support 610 is provided with a position sensor for detecting the packaging boxes on the secondary conveying belt 620 so as to control the actions of the secondary conveying belt 620, the lifting quantitative filling mechanism 630 and the two positioning clamping mechanisms 640. It should be noted that the two positioning clamping mechanisms 640 can clamp multiple packaging boxes at the same time so as to simultaneously fill the packaging boxes by the lifting quantitative filling mechanism 630, thereby improving the filling efficiency.

[0068] In addition, in order to facilitate filling and adapt to the aforementioned lotus root paste device 400, the lifting quantitative filling mechanism 630 comprises a temporary storage tank 631, a lifting seat 632 arranged on the support 610 in a lifting manner and a lifting mechanism 633 for driving the lifting seat 632 to lift. The temporary storage tank 631 is mounted on the support 610, the lifting seat 632 is provided with a plurality of filling pipes 634, the temporary storage tank 631 is in communication with all the filling pipes 634 through a supply pipe 635, each filling pipe 634 is provided with a quantitative valve 636, the temporary storage tank 631 is used for receiving and temporarily storing the lotus root paste discharged by the lotus root paste device 400, and the lotus root paste in the temporary storage tank 631 can automatically flow into all the filling pipes 634. The temporary storage tank 631 is in communication with the lotus root paste through a pipeline, and the pipeline is provided with a supply pump. When the packaging box is in place, the two positioning clamping mechanisms 640 are simultaneously extended and clamp the opposite sides of the packaging box, the lifting mechanism 633 is extended and drives the lifting seat 632 to descend, so that all the filling pipes 634 can be lowered for filling. In order to improve the filling efficiency, the present application can simultaneously fill multiple packaging boxes synchronously, thereby improving the filling efficiency. The lifting mechanism 633 can be a conventional lead screw motor structure or a telescopic cylinder structure.

[0069] The present application also provides a lotus root paste can production method, comprising the following steps:

[0070] Fresh lotus root powder processing: the harvested fresh lotus root is sequentially subjected to washing, node removal and soaking, and then subjected to fresh lotus root peeling and cleaning, fresh lotus root crushing and grinding, and residue-water separation to obtain lotus root powder slurry;

[0071] Multi-stage cyclone sorting: the obtained lotus root powder slurry is subjected to multi-stage cyclone circulation sorting by using multiple cyclone sorting devices to obtain unqualified products and qualified products, the unqualified products are sent into the fresh lotus root crushing and grinding device for secondary grinding, and the qualified products are sent into the next process after being drained;

[0072] Stirring and gluing: the drained qualified products and cold boiled water are added into the lotus root powder gluing device 300 for stirring, the stirring temperature is room temperature, and the stirring process is carried out in a vacuum state or under normal pressure protection gas environment; the mass ratio of the initial drained qualified products to cold boiled water is 1:1-2; the cold boiled water is gradually added during the stirring process as the viscosity of the mixture increases, and the stirring is stopped when the dynamic viscosity of the mixture is greater than 5 Pa.s; the total mass ratio of the final drained qualified products to cold boiled water is 1:2-4, and the gelled lotus root powder is obtained;

[0073] Pasting lotus root powder: the gelled lotus root powder is sent into the heating kettle 410 for stirring and heating, and a predetermined mass ratio of auxiliary materials is added during the stirring and heating according to the mass of the gelled lotus root powder; the heating temperature is 90-100℃, the heating pressure is normal pressure, and the stirring and heating time is 10-60 min; the pasted lotus root powder is obtained after the gelled lotus root powder is completely pasted, and the pasted lotus root powder is cooled and naturally vented until the temperature of the pasted lotus root powder is reduced to below 40℃;

[0074] Filling lotus root powder: the cooled and vented pasted lotus root powder is sent into the filling device 600 for filling, and then the packaging boxes discharged from the filling device 600 are sequentially sealed by the capping device 700;

[0075] Factory processing: the filled packaging boxes are subjected to high-temperature treatment, and then can be shipped, completing the production of lotus root powder cans.

[0076] In the processing step of fresh lotus root powder, the fresh lotus root crushing and grinding device can crush and grind the fresh lotus root residues and slurry after primary crushing at least twice, which is mainly to improve the fineness of the lotus root powder slurry and ensure the yield of lotus root powder. In the multi-stage cyclone separation step in the above embodiment, the inlet velocity of the multi-stage cyclone separation gradually increases, which is to improve the quality of the product and ensure the delicate taste of the lotus root powder. In addition, in this step, different lotus root glue making devices 300 can be directly connected to the overflow ports of different cyclones to produce lotus root powder with different particle sizes using the same set of cyclone equipment. In the stirring and glue making step, stirring and glue making can be carried out in a low temperature environment to avoid partial gelatinization of the lotus root powder slurry due to heat generated during stirring and glue making. Of course, stirring and glue making can also be carried out at room temperature in actual production, which can reduce the product taste but also reduce the production cost.

[0077] In addition, in the gelatinized lotus root powder step, the gelatinization can be completely heated at one time, or preliminary gelatinization can be carried out, which facilitates the filling in the filling step of lotus root powder, reduces the oxidation of lotus root powder by air, and then the secondary gelatinization can be carried out at high temperature sterilization in the factory processing step. Of course, the above processing process and the processing process of the present application can be selected according to the actual processing requirements. After the factory processing step, a detection step such as metal detection, air tightness detection, etc. is provided, and a packaging and warehousing step is also provided, which is set according to the actual use requirements.
