Description

Technical Field

[0001] The present invention relates to the technical field of food processing, in particular to a bamboo shoot impurity removal device. Background Art

[0002] Debonding technology is a core, pre-processing step in bamboo shoot processing, directly impacting product safety, appearance, and taste. Unremoved hard skin and coarse fibers can result in a rough texture, while residual mud or insect infestation poses hygiene risks. Market practice shows that thoroughly peeled bamboo shoots are more popular with buyers because they significantly reduce secondary processing costs. Oxalic acid and bitter substances are concentrated in the skin and roots, and deep rinsing after thorough debonding effectively dissolves astringent components, prevents turbidity in the soup, and optimizes flavor. Manual debonding accounts for over 30% of the total processing time, becoming a key bottleneck in increasing production capacity.

[0003] In the prior art, bamboo shoots are mainly removed by peeling them manually or mechanically, followed by soaking and rinsing. However, the manual treatment method is inefficient, while the mechanical treatment method often involves scratching the hard skin, bending the bamboo shoots mechanically to create a gap between the bamboo shoots and the shell, and then using a high-pressure water jet to rinse them. This is much more efficient than manual treatment. However, the above process consumes a huge amount of water, and because the bamboo shoot tips are composed of undifferentiated young thin-walled cells with loose cell arrangement and thin cell walls, they are easily broken or damaged during operation, affecting the appearance of the finished bamboo shoots and, in turn, the commercial value of the bamboo shoot products. Summary of the Invention

[0004] The present invention aims to provide a bamboo shoots impurity removal device to solve the above problems.

[0005] The present invention is achieved through the following technical solutions: A bamboo shoot impurity removal device comprises a frame, the frame is provided with an impurity removal bin and a discharge bin, the impurity removal bin is provided with an impurity removal component, the impurity removal bin is used for feeding and soaking bamboo shoots, the impurity removal component is used for processing the bamboo shoots, the discharge bin is provided with a discharge component, the discharge component is used for discharging the processed bamboo shoots, the impurity removal component comprises an aerator and a surge component, the surge component comprises a surge motor and a plurality of surge shafts, the surge shafts are all transmission-connected to the surge motor, the surge shafts are used to drive the liquid in the impurity removal bin to form a vortex, the vortex is used to flush impurities on the surface of the bamboo shoots, the vortex is also used to drive the bamboo shoot skins of the bamboo shoots to rub against each other and drive adjacent bamboo shoot skins to separate from adjacent bamboo shoots through the bamboo shoot skins, the aerator is connected to the impurity removal bin, the aerator is used to fill a mixed gas of carbon dioxide and pressurized air into the impurity removal bin, the mixed gas is used to reduce the pH value of the liquid in the impurity removal bin and drive the impurities and the bamboo shoot skins to separate from the bamboo shoots.

[0006] Compared with the prior art, the present invention has the following advantages and beneficial effects: In the present invention, the design of the surge component drives the bamboo shoot tips to collide with each other in the impurity removal bin, thereby realizing the stripping of the bamboo shoot shells. Compared with the existing technology, in the early stage of bamboo shoot tip processing, the bamboo shoot shells can contact a larger area of ​​the structure for removing the bamboo shoot shells, thereby greatly improving the shelling efficiency of the bamboo shoot tips. At the same time, the larger contact area also means that under the regulation of the same external force, the tensile stress per unit area of ​​the bamboo shoot tips in this solution is lower, and the probability of damage to the bamboo shoot tips is lower, which is conducive to improving the integrity of the bamboo shoot tip products.

[0007] At the same time, through the design of the aeration component, this solution pumps mixed gas into the de-impurity bin. Compared with the existing technology, this solution uses mixed gas to create a weak acid environment in the de-impurity bin, promotes the precipitation of calcium oxalate in the bamboo shoot tips, thereby improving the taste of the bamboo shoot tips. At the same time, the mixed gas can also peel off the mud adhering to the bamboo shoot tips and the bamboo shoot shells on the surface of the bamboo shoot tips, so as to achieve the purpose of improving the quality of the bamboo shoot tips.

[0008] Furthermore, the debris removal component also includes a number of scrubbing motors, which are fixedly connected to the frame, and the output shafts of the scrubbing motors are coaxially mounted with scrubbing shafts, which are arranged in the debris removal bin, and are used to scrub the bamboo shoots.

[0009] Beneficial effects: The design of the scrubbing shaft in this solution scrubs the bamboo shoot tips through the scrubbing shaft, helping the bamboo shoot shells to separate from the bamboo shoot tips. At the same time, the scrubbing shaft can also help remove dirt on the surface of the bamboo shoot tips. Compared with the existing technology, this solution can improve the device's de-impurity ability. At the same time, it also enables the device to maintain sufficient de-impurity ability when faced with a situation where there are fewer bamboo shoot tips and the probability of collision between bamboo shoot tips is reduced.

[0010] Furthermore, the impurity removal component also includes a filter residue motor and a filter residue drum, the filter residue drum is rotatably connected to the side wall of the impurity removal bin, the filter residue motor is used to drive the filter residue drum to rotate, a circulating water tank is provided under the filter residue drum, and the circulating water tank is connected to a circulating water pump, and the output end of the circulating water pump is connected to the impurity removal bin.

[0011] Beneficial effects: The design of the filter drum in this solution can separate and dehydrate the bamboo shoot shells floating on the liquid surface through the rotation of the filter drum, which reduces the operating steps of the operator and can also recycle and reuse the water attached to the bamboo shoot shells, thereby reducing the waste of water resources in the filter residue process and reducing the use cost of the device.

[0012] Furthermore, the impurity removal bin is connected to the discharge bin, and an electric gate is provided at the connection point between the impurity removal bin and the discharge bin.

[0013] Beneficial effects: This solution effectively improves the degree of automation of the bamboo shoot production line through the design of the electric gate. The opening speed and stroke of the electric gate can be adjusted more accurately. During operation, the device can be isolated from the operator to avoid damage to the operator's body caused by electrical components in the de-waste bin and the discharge bin.

[0014] Furthermore, the discharging assembly includes a discharging conveying motor, and a discharging conveying chain plate is installed in the discharging bin. The discharging conveying motor is used to drive the discharging conveying chain plate to work, and the discharging conveying chain plate is used to discharge the processed bamboo shoots from the de-impurity bin.

[0015] Beneficial effect: In this solution, a discharging conveyor chain plate is used to realize the discharging operation of the bamboo shoot tips. Compared with the existing technology, this solution can connect the subsequent processing process of the bamboo shoot tips through the discharging conveyor chain plate, thereby further reducing the manual participation of the bamboo shoot tip production line.

[0016] Furthermore, a spray head is provided at the connection point between the de-impurity bin and the circulating water pump, and the spray head is used to perform pressurized atomization treatment on the liquid input by the circulating water pump.

[0017] Beneficial effects: The design of the spray head in this solution not only reduces the waste of water resources during the bamboo shoot shelling process, but also pre-treats the scum to improve the subsequent dehydration rate of the scum.

[0018] Furthermore, a drain valve is provided on the bottom wall of the discharge bin, and a filter is provided at the connection point between the discharge bin and the drain valve.

[0019] Beneficial effect: The design of the drain valve and filter in this solution makes it easier for operators to change water during the processing of bamboo shoot tips. At the same time, the filter can prevent the sediment washed off the surface of the bamboo shoot tips from clogging the drain valve.

[0020] Furthermore, the scrubbing shafts rotate alternately.

[0021] Beneficial effect: Compared with the existing technology, the alternative rotation of the scrubbing shaft in this solution can effectively avoid the dead angles that may be caused by synchronous rotation, and improve the scrubbing effect of the scrubbing shaft on the bamboo shoot tips.

[0022] Furthermore, the device further includes a monitoring component, which includes a plurality of monitoring balls, each of which has a detection cavity inside, and is used to allow the solution in the decontamination cavity to enter the detection cavity and adsorb calcium ions in the solution in the decontamination cavity. A calcium ion sensor is provided in the detection cavity, and the calcium ion sensor is used to collect the calcium ion content in the liquid in the decontamination cavity. It also includes a control system, which is used to determine whether the monitoring ball is saturated according to the content of calcium ions, and output prompt information to the user when the monitoring ball is saturated.

[0023] Beneficial effects: This solution uses a monitoring ball to adsorb calcium ions through the design of a monitoring component, and simultaneously uses a calcium ion sensor to monitor the calcium ions inside the monitoring ball to determine when the monitoring ball is saturated, and thereby determine the effect of removing calcium oxalate from the bamboo shoot tips in the de-waste bin. Compared with the existing technology, this solution can reduce the softening of the bamboo shoot tips caused by soaking for too long, which may affect the quality of the finished bamboo shoot tips.

[0024] Furthermore, a plurality of magnetic particles are provided in the monitoring ball, and an electromagnet is provided on the side wall of the de-impurity bin. The electromagnet is used to adsorb the monitoring ball through the magnetic particles. The control system is used to control the discharge component and the electromagnet after determining that the monitoring ball is saturated.

[0025] Beneficial effect: This solution utilizes the design of an electromagnet to realize the automatic collection and fixation of the monitoring ball. Compared with the existing technology, it can effectively avoid the influence of the monitoring ball on the discharge of the bamboo shoot tip, and it is also convenient for the operator to replace or regenerate the monitoring ball.

[0028] To make the objectives, technical solutions, and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the examples and accompanying drawings. The exemplary embodiments of the present invention and their descriptions are only used to explain the present invention and are not intended to limit the present invention. It should be noted that the present invention is already in the actual development and use stage.

[0029] Example 1 like Figure 1As shown, this embodiment includes a frame 1, which is provided with a de-impurity bin 4 and a discharging bin 3. The de-impurity bin 4 is provided with a de-impurity component 5, the de-impurity bin 4 is used for feeding and soaking bamboo shoots, the de-impurity component 5 is used for processing the bamboo shoots, and the discharging bin 3 is provided with a discharging component 2, the discharging component 2 is used to discharge the processed bamboo shoots.

[0030] The impurity removal component 5 includes an aerator 59 and a surge component. The surge component is used to drive the liquid in the impurity removal bin 4 to form a vortex. The vortex is used to wash impurities on the surface of the bamboo shoots. The vortex is also used to drive the skins of the bamboo shoots to rub against each other and drive adjacent skins of the bamboo shoots to separate from adjacent bamboo shoots through the skins of the bamboo shoots.

[0031] The surge assembly includes a surge motor 52 and several surge shafts 51. The surge shafts 51 are all rotatably connected to the side walls of the de-impurity bin 4, and the surge shafts 51 are all connected to the surge motor 52 through a transmission belt. The surge motor 52 is fixedly connected to the frame 1 by bolts.

[0032] The aerator 59 is connected to the impurity removal bin 4, and the exposure machine is fixedly connected to the frame 1 by bolts. The aerator 59 is used to fill the impurity removal bin 4 with a mixed gas of carbon dioxide and pressurized air. The mixed gas is used to reduce the pH value of the liquid in the impurity removal bin 4 and drive the impurities and the bamboo shoot skin to separate from the bamboo shoots.

[0033] The de-impurity component 5 also includes a number of scrubbing motors 57, which are fixedly connected to the frame 1. The output shafts of the scrubbing motors 57 are coaxially and detachably connected to the scrubbing shafts 56. The scrubbing shafts 56 rotate alternately, and the speed is stable at 30 revolutions per minute (rpm), allowing a fluctuation range of ±5 rpm. The scrubbing shafts 56 are all arranged in the de-impurity bin 4. The scrubbing shafts 56 are used to scrub the bamboo shoots. The scrubbing shafts 56 are all arranged in the de-impurity bin 4, and the outer walls of the scrubbing shafts 56 are provided with scrubbing textures that simulate the patterns of bamboo shoot shells.

[0034] The impurity removal bin 4 is communicated with the discharge bin 3 , and an electric gate 58 is provided at the connection point between the impurity removal bin 4 and the discharge bin 3 . The electric gate 58 is fixedly connected to the frame 1 by bolts.

[0035] The discharging assembly 2 includes a discharging conveying motor 22, and a discharging conveying chain plate 21 is installed in the discharging bin 3. The discharging conveying chain plate 21 is fixedly connected to the side wall of the discharging bin 3 by bolts, and the discharging conveying motor 22 is fixedly connected to the top wall of the discharging bin 3 by bolts, and the output shaft of the discharging conveying motor 22 is connected to the discharging conveying chain plate 21 through a transmission belt. The discharging conveying motor 22 is used to drive the discharging conveying chain plate 21 to work, and the discharging conveying chain plate 21 is used to discharge the processed bamboo shoots from the de-impurity bin 4.

[0036] The specific operation method is as follows: when using this device, the bamboo shoot tips are selected, and those with problems such as damage and insect pests are removed. Then they are cut to retain the length that meets the subsequent production requirements, and are divided equally according to weight and put into this device.

[0037] After the bamboo shoots enter the debonding chamber 4, the operator activates the device and adds warm water to the chamber. Upon activation, the surge motor 52 drives the surge shaft 51, which in turn causes the water in the debonding chamber 4 to surge, thereby causing the bamboo shoot tips in the water to surge. During this surge, the bamboo shoot tips collide with each other, causing adjacent bamboo shoot shells to rub against each other. Because the outer shells (i.e., bamboo shoot shells) of natural bamboo shoot tips are rough, when the shells of adjacent bamboo shoot tips rub against each other, the friction between the two shells increases as the degree of collision between the bamboo shoot tips deepens. Subsequently, the bamboo shoot tips separate due to the eddy current, while the bamboo shoot shells, due to friction, are unable to follow the movement of the bamboo shoot tips. At this point, the bamboo shoot shells detach from the bamboo shoot tips, completing the shelling of the bamboo shoot tips.

[0038] During this process, the aerator 59 continuously pumps pressurized air mixed with a small amount of carbon dioxide (i.e., mixed gas) into the de-impurity bin 4. As the mixed gas enters the de-impurity bin 4, the carbon dioxide in the mixed gas dissolves in the water to form carbonic acid, etc., thereby reducing the pH value of the solution in the de-impurity bin 4 and helping the calcium oxalate in the bamboo shoot tips to precipitate faster.

[0039] As the surge shaft 51 works, the bamboo shoot tips are exposed to the solution in the de-impurity chamber 4, and the carbonic acid formed at the same time quickly diffuses in the solution, causing the pH value of each position of the solution to decrease synchronously, helping the bamboo shoot tips at each position to precipitate calcium oxalate.

[0040] At the same time, due to its high air pressure, after the mixed gas enters the de-impurity chamber, it pushes the bamboo shoot shells separated from the bamboo shoot tips to move toward the liquid surface, thereby avoiding the entanglement of the bamboo shoot shells and the bamboo shoot tips, affecting the subsequent processing of the bamboo shoot tips. At the same time, the gas with a high pressure can also wash away the stubborn mud and sand adhering to the surface of the bamboo shoot tips when it comes into contact with the bamboo shoot tips, thereby preventing the mud and sand from affecting the quality of the bamboo shoot tips.

[0041] While the surge shaft 51 is working, the operator can judge whether to use the scrubbing shaft 56 according to the size of the bamboo shoot tip and the thickness of the bamboo shoot shell, as well as the working power of the scrubbing shaft 56 when in use. When the scrubbing shaft 56 needs to be used, the operator turns on the scrubbing motor 57, and the scrubbing motor 57 drives the corresponding scrubbing shaft 56 to rotate. As the scrubbing shaft 56 rotates, the texture on the outer surface of the scrubbing shaft 56 rubs against the bamboo shoot shell, thereby peeling the bamboo shoot shell off from the bamboo shoot tip, thereby further processing the bamboo shoot tip. At the same time, the texture of the outer wall shape of the bamboo shoot shell is used to simulate the shape of the outer wall of the bamboo shoot shell. Compared with the existing technology, it can reduce the damage of the scrubbing shaft 56 to the bamboo shoot tips, and greatly improve the integrity of the bamboo shoot tips after the processing is completed. At the same time, the design of the scrubbing shaft 56 can face the situation where the number of bamboo shoot tips is small and the probability of collision between bamboo shoot tips is reduced. The device can still maintain a certain ability to peel the bamboo shoot tips. When the number of bamboo shoot tips is large, the device can also increase the scrubbing and peeling efficiency through the scrubbing shaft 56, and can also use the scrubbing shaft 56 to brush the peeled bamboo shoot tips, thereby improving the cleanliness of the bamboo shoot tips at the subsequent discharge position.

[0042] The design of the surge shaft 51 in the present solution creates a vortex in the de-shredding bin 4, helps the bamboo shoot tips to collide with each other, and utilizes the rough outer walls of the bamboo shoot tips to rub against each other, thereby achieving the purpose of removing the bamboo shoot shells. Compared with the existing solutions using rollers or brushes, in the present solution, in the early stage of peeling, the bamboo shoot shells can contact a larger area of ​​the structure for removing the bamboo shoot shells (for example, when using rollers for shelling, only the provided rollers can be used to help the bamboo shoot tips for shelling, while in the present solution, each bamboo shoot tip can help the adjacent bamboo shoot tips to shell themselves), which significantly improves the shelling efficiency. At the same time, since the bamboo shoot tips are not fixed, in the process of the bamboo shoot tips following the vortex movement, each part of the bamboo shoot tips at each position can contact the adjacent bamboo shoot tips. Compared with the existing technology, the contact area between the bamboo shoot shells and the structure for removing the bamboo shoot shells in the present solution is larger. Under the same external force conditions, the tensile stress per unit area is smaller, and the bamboo shoot tips are not easily broken due to stress concentration, thereby improving the integrity of the bamboo shoot tips.

[0043] At the same time, in this solution, through the design of the aerator 59, pressurized air mixed with carbon dioxide is pumped into the de-impurity bin 4 through the aerator 59 to adjust the pH value of the water in the de-impurity bin 4, and in the process of processing the bamboo shoot tips, the water in the de-impurity bin 4 maintains a certain weak acidity, thereby promoting the precipitation of calcium oxalate in the bamboo shoot tips, removing part of the bitterness in the bamboo shoot tips and reducing its rough taste. Compared with the existing technology, in this solution, the pH value of the solution in the de-impurity bin 4 can be effectively maintained within a certain range by continuously introducing mixed gas, avoiding the frequent water changes in the existing technology for maintaining the pH value of the solution for soaking the bamboo shoot tips, effectively reducing the operating steps of the operator, and improving the precipitation efficiency of calcium oxalate in the bamboo shoot tips.

[0044] The introduction of mixed gas can also wash away the mud and sand attached to the surface of the bamboo shoot tips and remove the bamboo shoot shells around the bamboo shoot tips to prevent the bamboo shoot shells from being entangled on the bamboo shoot tips and affecting the quality of the bamboo shoot tips. When the bamboo shoot shells float to the surface of the liquid, the operator can separate them from the solution.

[0045] After the bamboo shoot tips are processed, the operator can start the electric gate 58. As the electric gate 58 rises, the impurity removal bin 4 is connected to the discharge bin 3, and the solution in the impurity removal bin 4 carries the processed bamboo shoot tips into the discharge bin 3. Then the operator starts the discharge conveying motor 22, and the discharge conveying motor 22 drives the discharge conveying chain plate 21 to work. The discharge conveying chain plate 21 mobilizes the bamboo shoot tips to move upward and separate from the discharge bin 3, completing the preliminary processing of the bamboo shoot tips.

[0046] In this solution, the scrubbing shafts 56 are rotated alternately, and each scrubbing shaft 56 is started alternately according to a preset sequence or program, thereby avoiding scrubbing dead angles caused by synchronous rotation.

[0047] Example 2 The difference from the above embodiment is that: the impurity removal component 5 also includes a filter residue motor and a filter residue drum 55, the filter residue drum 55 is rotatably connected to the inner side wall of the impurity removal bin 4, the filter residue motor is used to drive the filter residue drum 55 to rotate, the filter residue motor is fixedly connected to the frame 1 by bolts, and the output end of the filter residue motor is transmission-connected to the filter residue drum 55 through a transmission belt, a circulating water tank 54 is provided below the filter residue drum 55, and the circulating water tank 54 is connected to a circulating water pump 53, the circulating water tank 54 and the circulating water pump 53 are both fixedly connected to the frame 1 by bolts, and the output end of the circulating water pump 53 is connected to the impurity removal bin 4.

[0048] A spray head is provided at the connection point between the impurity removal bin 4 and the circulating water pump 53 , and the spray head is used to atomize the liquid input by the circulating water pump 53 and to pressurize the atomized liquid.

[0049] The bottom wall of the discharge bin 3 is provided with a drain valve. In this embodiment, the drain valve is a quick-close drain valve, and a double-layer filter screen is bonded and fixed at the connection between the discharge bin 3 and the drain valve.

[0050] The specific implementation method is as follows: During the use of this device, when the surge shaft 51 and the scrubbing shaft 56 are in operation, the bamboo shoot shells detach from the bamboo shoot tips and float on the liquid surface under the action of the mixed gas. As the surge shaft 51 operates, the bamboo shoot shells move to the edge of the decontamination bin 4. At the same time, the filter residue motor operates, driving the filter residue drum 55 to rotate in the opposite direction of the water flow. The bamboo shoot shells attached to the outer surface of the filter residue drum 55 follow the movement of the filter residue drum 55 and reach its top. Under the action of gravity and centrifugal force, some of the water in the bamboo shoot shells flows downward into the circulating water tank 54, while the bamboo shoot shells continue to follow the operation of the filter residue drum 55 until they are separated from the filter residue drum 55 under the action of gravity.

[0051] The liquid entering the circulating water tank 54 enters the spray head under the action of the circulating water pump 53, is pressurized and atomized by the spray head, and is finally sprayed on the bamboo shoots on the liquid surface in the de-impurity bin 4 in the form of high-pressure fan-shaped water mist, so as to pre-wash the bamboo shoots to adjust the moisture content and fluidity of the bamboo shoots, thereby improving the efficiency of subsequent filtration of bamboo shoot moisture and the water recovery rate.

[0052] At the same time, during the discharging process, the liquid entering the discharge bin 3 can leave the device through the drain valve, realizing rapid water replacement. At the same time, the design of the filter screen prevents the mud and sand in the liquid from entering the drain valve synchronously, causing the drain valve to be blocked.

[0053] Compared with the existing technology, this solution uses the design of the filter drum 55 to timely separate and clean the scum (bamboo shoot shells) on the liquid surface, thereby preventing the scum from adversely affecting the quality of the bamboo shoot tips. At the same time, the filter drum 55 is used to dehydrate the scum, and the design of the circulating water pump 53 is used to achieve the reuse of the liquid in the decontamination bin 4, thereby reducing the waste of water resources.

[0054] Example 3 like Figure 2 As shown, the difference from the above embodiment is that it also includes a monitoring component, which includes a plurality of monitoring balls 6. The material of the monitoring balls 6 is ion exchange resin. A detection cavity 61 is provided inside the monitoring balls 6. The monitoring balls 6 are used to allow the solution in the decontamination chamber to enter the detection cavity 61 and adsorb calcium ions in the solution in the decontamination chamber. A calcium ion sensor 62 is provided in the detection cavity 61. The calcium ion sensor 62 is bonded and fixed to the monitoring balls 6. The calcium ion sensor 62 is used to collect the calcium ion content in the liquid in the decontamination chamber. The monitoring ball 6 is provided with a plurality of magnetic particles, and the magnetic particles are evenly distributed in the monitoring ball 6. An electromagnet 41 is fixedly connected with the side wall of the de-impurity bin 4 by bolts, and the electromagnet 41 is used to adsorb the monitoring ball 6 through the magnetic particles.

[0055] It also includes a control system, which includes a controller and a communication module. The communication module is used to output signals to the user. The communication module and the controller are fixedly connected to the frame 1 by bolts. The electromagnet 41, the electric gate 58, the calcium ion sensor 62 and the communication module are all connected to the controller signal. The controller is used to determine whether the monitoring ball 6 is saturated based on the content of calcium oxalate, and control the communication module to output prompt information to the user when the monitoring ball 6 is saturated. The controller is also used to control the discharge component 2 and the electromagnet 41 to work after determining that the monitoring ball 6 is saturated.

[0056] The specific implementation method is as follows: When using this solution, the monitoring ball 6 is put into the de-impurity bin 4, and then the device can be started. As the surge shaft 51 rotates, the monitoring ball 6 moves with the solution of the bamboo shoot tip in the de-impurity bin 4 to adsorb the free calcium ions in the solution. At the same time, since the ion exchange resin has a certain gap, part of the solution can enter the detection cavity 61. At the same time, during the process of the solution entering, the ion exchange resin adsorbs the calcium ions in the solution.

[0057] At this time, the calcium ion sensor 62 continuously monitors the calcium ion content of the solution in the detection chamber 61. When the ion exchange resin is not saturated, there are no calcium ions or only trace amounts of calcium ions in the detection chamber 61. When the ion exchange resin is saturated, the ion exchange resin can no longer absorb the calcium ions in the solution, allowing some calcium ions to pass through the ion exchange resin into the detection chamber 61.

[0058] Thus, based on the calcium ion content within detection chamber 61 collected by calcium ion sensor 62 (the calcium ion content can be used to infer the calcium oxalate content within detection chamber 61), it is possible to determine whether monitoring ball 6 is saturated. Since data such as the temperature of the solution within decontamination chamber 4, the number of bamboo shoot tips within decontamination chamber 4, and the type of bamboo shoot tips within decontamination chamber 4 are all known, the operator can roughly estimate the approximate calcium oxalate concentration in the solution after the calcium oxalate in the bamboo shoot tips within decontamination chamber 4 has precipitated. Based on this calculated theoretical value, and since there are no precise regulations for the residual calcium oxalate content during bamboo shoot processing, the operator can design a reasonable confidence interval for the theoretical value based on the subsequent processing requirements of the bamboo shoot tips, forming a theoretical range. The operator can then adjust the size and material of monitoring ball 6 so that the monitoring ball 6 is saturated when the calcium oxalate concentration in the solution reaches the set theoretical range, just as the theoretical value is reached.

[0059] When the monitoring ball 6 is saturated, the controller outputs a prompt signal to the user through the communication module, prompting the user that the material can be discharged at this time.

[0060] At the same time, the controller starts the electromagnet 41, which adsorbs the monitoring ball 6, and then starts the electric gate 58 and the discharge conveying motor 22, so that the bamboo shoots in the de-impurity bin 4 enter the discharge bin 3 and leave the device under the action of the discharge conveying chain plate 21, while achieving the adsorption of the bamboo shoots and the monitoring ball 6.

[0061] Compared with the existing technology, this solution realizes the monitoring of the calcium oxalate content in the solution during the processing of bamboo shoot tips through the design of the monitoring ball 6, and then judges the effect of removing calcium oxalate from the bamboo shoot tips. While avoiding insufficient soaking time of the bamboo shoot tips, poor calcium oxalate removal effect, and affecting the taste of the subsequent finished bamboo shoot tips, it can also avoid the bamboo shoot tips being soaked in the weak acid solution for too long, which will soften the texture and lose nutrients, affecting the quality of the finished bamboo shoot tips.

[0062] Compared to existing manual judgment methods, this solution combines numerical settings during several bamboo shoot tip processing steps with actual processing results to create a database of bamboo shoot processing parameters. This facilitates standardized subsequent bamboo shoot processing and improves the quality of subsequent bamboo shoots. Furthermore, this solution eliminates the need for workers to directly interact with the production line during the process of determining the effectiveness of calcium oxalate removal, significantly reducing the likelihood of safety accidents during operation.

[0063] Compared to solutions that directly use the calcium ion sensor 62 to monitor the calcium ion content of the solution, the calcium ion sensor 62 in this solution can move with the surge of the solution, preventing the accumulation of calcium oxalate in a certain portion and causing misjudgment. At the same time, compared to solutions that directly place the wireless calcium ion sensor 62 in the solution, the probe of the calcium ion sensor 62 and other important locations in this solution are not directly exposed to the decontamination chamber 4. This can reduce the probability of the surge shaft 51 and the scrubbing shaft 56 damaging the probe of the calcium ion sensor 62 and increase the service life of the calcium ion sensor 62.

[0064] At the same time, in actual application scenarios, the distribution of calcium oxalate and other substances at various positions in the solution of the decontamination chamber is not uniform. The design of the monitoring ball 6 in this solution can absorb the calcium ions around the monitoring ball 6, so that the monitoring ball 6 can reflect the state of the solution within a certain range around it, thereby further reducing the calcium ion concentration at the head-up probe position of the calcium ion sensor 62 being greater or less than the calcium ion concentration at other positions of the solution due to factors such as the accumulation of calcium oxalate at a certain position, thereby causing misjudgment and affecting the processing quality of the bamboo shoot tips.

[0065] In this solution, the design of electromagnet 41 allows for the separation of monitoring ball 6 during the discharge process, preventing it from interfering with the discharge of bamboo shoot tips. Furthermore, the monitoring ball 6 is secured to the inner wall of the decontamination bin 4, allowing operators to directly retrieve or replace the monitoring ball 6 or inject a regeneration agent directly into the decontamination bin 4 to regenerate the monitoring ball 6.
