Description

Technical Field

[0001] This invention relates to an automated line and method for processing sheet silk, belonging to the field of sheet silk processing technology. Background Technology

[0002] Thousand-layer tofu, or qianzhang, is a special type of bean curd product. It's a thin slice of dried tofu, which can be understood as a particularly large, thin, and somewhat chewy piece of dried tofu. It's yellowish in color and can be eaten cold, stir-fried, or boiled. Thousand-layer tofu is inexpensive and suitable for most people, especially those who are weak, malnourished, have blood and qi deficiency, or are elderly and thin.

[0003] After the tofu skin is made, it is usually shredded and soaked. Shredding is to optimize the cooking experience and subsequent processing, while soaking in brine is to improve the taste, extend the shelf life and give it a basic flavor.

[0004] Existing equipment has patents related to the shredding and brine soaking of dried tofu sheets, such as CN113575857A, "A Fusion Processing Method for Dried Tofu Sheets and Vermicelli," which involves shredding and soaking processes, but does not involve specific related equipment. Existing shredding equipment, such as CN205386838U, is a dried tofu sheet shredding machine that uses a motor to drive vertical blades for cutting.

[0005] In the soaking process, there is a processing device, such as CN215455201U, that uses weakly acidic electrolyzed water to preserve dried tofu sheets. This device soaks the tofu sheets in weakly acidic electrolyzed water for preservation and can simultaneously perform soaking and drying treatments on two separate tofu sheet preservation frames using a soaking and water-controlling rack. However, it cannot be used on a continuous conveyor line; it is a standalone soaking and processing device that requires manual pushing of the raw materials in and out.

[0006] The following problems exist:

[0007] 1) For the soaking process of shredded tofu sheets, the current lifting method cannot perform continuous soaking and conveying functions, and is not compatible with continuous production lines;

[0008] 2) The existing air-cooled tofu skin strips are not completely cooled, which can easily lead to excessive moisture in the product, affecting its quality and taste.

[0009] Therefore, an automated line and processing method for processing thousand-sheet wire are proposed to solve the above problems. Summary of the Invention

[0010] The purpose of this invention is to overcome the shortcomings of the prior art and propose an automated processing line and method for processing dried tofu skin, thereby solving the technical problems of continuous transport during impregnation and incomplete moisture removal during air cooling in existing dried tofu skin processing methods. This invention discloses an automated processing line and method for processing dried tofu skin, comprising:

[0011] A shredder, comprising an inclined conveyor belt and a cutting blade holder, wherein a pair of cutting rollers are installed inside the cutting blade holder;

[0012] An impregnation chamber includes an outer casing and an impregnation conveyor box. The impregnation conveyor box is installed inside the outer casing. A landing gear is installed on the outer casing. A lifting assembly is installed on the landing gear. The lifting assembly is used to lift the impregnation conveyor box.

[0013] The transition conveyor frame includes a transition conveyor net and an air-cooled frame 1, with the air-cooled frame 1 facing outwards from the transition conveyor net; the impregnation conveyor box is open at the end of the transition conveyor frame.

[0014] Vibration box;

[0015] The reciprocating drying rack includes a drying conveyor, a second air-cooled rack, and a spiral drying box. The second air-cooled rack outputs to the drying conveyor. The spiral drying box is used for feeding and drying the dried tofu sheets.

[0016] In a further technical solution, the cutting tool holder includes a tool holder shell, and a pair of cutting rollers are installed inside the tool holder shell. The pair of cutting rollers includes two sets of rollers, each set of rollers having a cutting edge and a cutting groove, and a cutting groove is provided between adjacent cutting edges; the cutting edges of the two sets of rollers are staggered.

[0017] A set of hobs is axially mounted with a drive motor, which is installed outside the tool holder housing.

[0018] A guide plate is mounted on the cutting roller; one end of the inclined conveyor belt extends to the blade holder.

[0019] A second inclined conveyor belt is installed at the tail end of the shredder, and the top of the second inclined conveyor belt extends to the impregnation tank.

[0020] In a further technical solution, the second inclined conveyor belt is inclined and its top is higher than the height of the outer box sticker;

[0021] The impregnation conveyor box is equipped with an impregnation conveyor net; the impregnation box is filled with brine.

[0022] The impregnation conveyor box is equipped with a lateral inclined trigger, which drives the impregnation conveyor to rotate.

[0023] Lifting lugs are installed on the impregnation conveyor box, and lifting shafts are installed on the lifting lugs; at least two sets of parallel lifting assemblies are installed on the lifting gear, and each set of lifting assemblies is respectively lifted at both ends of the corresponding lifting shaft; the two sets of lifting assemblies are used to lift the impregnation conveyor box and tilt it downward toward the transition conveyor frame.

[0024] In a further technical solution, the impregnation conveying box is laterally mounted with a track groove, and the inclined pull trigger includes a slider, which is constrained to slide within the track groove;

[0025] The outer end of the slider is equipped with a connector and a constraint. The connector connects the slider to the impregnation conveyor network; the constraint connects the slider to the impregnation conveyor box.

[0026] Limit switch one and limit switch two are respectively installed at the front and rear ends of the track groove to control the tilt reset and the descent action of the immersion conveyor box.

[0027] When the impregnation conveyor is tilted at an angle greater than A, the slider slides in the track groove, causing the tofu skin on the impregnation conveyor to move toward the transition conveyor frame.

[0028] In a further technical solution, the constraint member includes a mounting base and a rod. The mounting base is installed inside the immersion tank, and a column head is provided on the mounting base. The column head is rotatably connected to the rod.

[0029] A tension spring is installed at the end of rod one away from the column head, and one end of the tension spring is constrained and fixed to rod one; a fixed column is installed on the slider, and a hinge joint is installed at the outer end of the fixed column, and rod two is installed on the hinge joint; the other end of the tension spring is constrained and fixed to rod two.

[0030] A support frame is installed at the bottom of the slider, and a load block can be detachably installed on the support frame.

[0031] In a further technical solution, the lifting assembly includes a lifting motor and a winch. The lifting motor and the winch are coaxially connected. A lifting rope is installed on the winch, and the end of the lifting rope is connected to the lifting shaft. The bottom of the winch is detachably connected to the landing gear.

[0032] Guide wheels are also installed on the landing gear to constrain the direction of the lifting ropes.

[0033] In a further technical solution, a discharge drive and a discharge conveyor are installed at the tail of the impregnation tank. The discharge drive drives the discharge conveyor to rotate, causing the tofu skin to be discharged upwards.

[0034] Material plates are installed at equal intervals on the discharge conveyor network, and the material plates can be detachably installed on the discharge conveyor network.

[0035] In a further technical solution, an air-cooled fan is installed on the air-cooled frame and is directed toward the transition conveyor network for output;

[0036] The vibration box includes a fixed base and an inclined vibration net. The inclined vibration net is fitted with a vibration spring on its side and bottom and fixed to the fixed base by the vibration spring. A vibration motor is installed on the inclined vibration net.

[0037] The inclined vibrating net tilts downwards from one end near the transition conveyor towards the end of the reciprocating drying rack.

[0038] In a further technical solution, the drying conveyor network is provided with multiple layers, and a drive roller is installed inside. A transmission motor is installed outside the drive roller to drive the corresponding drying conveyor network to rotate.

[0039] The length of the drying conveyor network of the next layer is greater than the length of the drying conveyor network of the previous layer, and the horizontal positions of the two ends of the drying conveyor network of the next layer extend beyond the horizontal positions of the two ends of the drying conveyor network of the previous layer.

[0040] The spiral drying chamber includes a feed inlet located at the bottom of the multi-layer drying conveyor network; a position fan is installed on the reciprocating drying rack, with its output end connected to and facing the spiral drying chamber;

[0041] The spiral drying chamber is equipped with a main shaft and spiral blades. The output end of the position fan is eccentrically set with the main shaft. When the position fan outputs, the air force drives the spiral blades to transport the tofu skin downwards.

[0042] An air chamber is provided inside the main shaft, and an air supply pipe is installed inside the air chamber; a fixing strip is provided on the side of the spiral blade, and an air bladder tube is installed in the fixing strip. An air hole one is provided on the side of the air bladder tube facing the main shaft, and the air bladder tube is connected to the air supply pipe inside the main shaft; an air hole two is provided on the spiral drying oven.

[0043] The processing method of the automated line for processing sheet silk includes the following steps:

[0044] Step 1: The tofu sheets are laid flat on the inclined conveyor belt and fall vertically into the cutting blade holder; the cutting blades inside the cutting blade holder cut the tofu sheets to form tofu strips.

[0045] Step 2: The tofu skin shreds are transported onto the impregnation conveyor network via the inclined conveyor belt 2. After the cutting of a single batch of tofu skin shreds is completed, the shredder is paused.

[0046] Step 3: Fill the soaking tank with brine beforehand and test the brine concentration. Once it meets the standard, fill it with the dried tofu strips from Step 2.

[0047] The impregnation time should be controlled between 20 and 40 minutes, and the concentration range should be 1-3%.

[0048] a. After the tofu skin strips are soaked, the lifting assembly raises the soaking conveyor box, causing the tofu skin strips to be removed from the brine, and stops for 2-5 minutes; then, the control cabinet controls one set of lifting assemblies facing the shredder to continue to rise, while the other set of lifting assemblies stops rising; the lifting continues, and the soaking conveyor belt tilts downward toward the transition conveyor frame, with its height higher than the bottom height of the discharge conveyor belt; the slider drives the soaking conveyor belt to rotate, causing the tofu skin strips to fall onto the discharge conveyor belt;

[0049] b. When the impregnation conveyor is tilted, the slider slides down. Under the action of the load block, the slider abuts against the limit switch at the end, causing the lifting rope of the lifting assembly toward the shredder to descend until the bottom of the two sets of lifting ropes are at the same level.

[0050] c. The tension spring inside the constraint pulls the slider back to its original position along the track groove towards the shredder;

[0051] d. A reset drive cylinder is installed inside the impregnation tank. The output end of the reset drive cylinder is connected to the mounting base. When the two sets of lifting ropes are at the same level again in step B, the output end of the reset drive cylinder moves toward the shredder. When the slider abuts against the limit switch two, the two sets of lifting components are controlled to descend through signal transmission until the impregnation conveyor box is placed inside the impregnation tank.

[0052] Step 4: The dried tofu sheets are conveyed by the discharge conveyor and fall onto the transition conveyor, where they are dehydrated by air cooling frame 1.

[0053] Step 5: The transition conveyor wire drops the tofu skin onto the inclined vibrating screen for vibration dehydration;

[0054] Step 6: An inclined conveyor belt is installed at the end of the reciprocating drying rack, which is driven to the top drying conveyor belt; it is then conveyed through the multi-layer drying conveyor belt and dried by the air-cooled fan installed on the second air-cooled rack.

[0055] Step 7: The bottom drying conveyor feeds the tofu skin shreds into the feed inlet. The feed inlet is set at an angle to feed the tofu skin shreds onto the spiral blades. The position fan blows the spiral blades to rotate, causing the tofu skin shreds on the spiral blades to roll off until they reach the bottom discharge port.

[0056] Simultaneously, gas is introduced into the air supply pipe inside the main shaft to ensure the position of the tofu skin strands;

[0057] Complete the processing of thousand-sheet silk.

[0058] Compared with the prior art, the present invention can achieve the following technical effects:

[0059] This invention achieves staged soaking of dried tofu strips by lifting the impregnation conveyor box using a hoisting method. A set of lifting components lifts one end of the impregnation conveyor box, tilting it, and then a diagonal pull triggers the movement of the impregnation conveyor network, moving the tofu strips forward. A slider within a constraint component moves within a track groove, triggering a limit switch, which resets the hoisting motor of the lifting component, automatically returning the impregnation conveyor box to a horizontal position. Then, the constraint component and a reset drive cylinder cause the slider to reset and abut against a limit switch, causing the hoisting motor to drive the lifting rope to lower the impregnation conveyor box, achieving the reset effect. This structure enables automatic draining, tilting and unloading, and reset actions, achieving brine impregnation of the dried tofu strips.

[0060] This invention employs a quadruple air-cooling system—including a first air-cooled fan, a vibrating chamber, a second air-cooled fan, and a positional fan—to achieve thorough drying of the tofu skin strands. The tofu skin strands are driven by a spiral blade within the spiral drying chamber. This spiral blade is rotated by an eccentric positional fan, and the air is blown inwards through the air supply pipes and air bladder pipes on the main shaft. This causes the tofu skin strands to gather outside the main shaft, facilitating thorough drying and achieving a dual effect of rotational feeding and drying. Attached Figure Description

[0089] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0090] The application principle of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0091] Example 1

[0092] like Figure 1-12 The diagram illustrates one embodiment of the present invention, specifically an automated line for processing sheet wire, comprising:

[0093] like Figure 2-4 The diagram shows the structure of a shredder. The shredder 1 includes an inclined conveyor belt 11 and a cutting blade holder 12. A pair of cutting rollers 13 are installed inside the cutting blade holder 12. The cutting blade holder 12 includes a blade holder housing, inside which the pair of cutting rollers 13 are installed. The pair of cutting rollers 13 includes two sets of rollers 131, as shown... Figure 4 As shown, both sets of hobs 131 are provided with a cutting edge 132 and a cutting groove 133, wherein the cutting edge can also be set as a pointed cutting edge for easy cutting; a cutting groove 133 is provided between adjacent cutting edges 132; the cutting edges 132 of the two sets of hobs 131 are staggered; a drive motor 14 is axially mounted on one set of hobs 131, as shown in the figure. Figure 2 As shown, the drive motor 14 is installed outside the blade holder housing, and its output end extends into the blade holder housing and is connected to a set of rollers via a coupling; a guide plate 15 is installed on the cutting rollers 13; one end of the inclined conveyor belt extends to the blade holder housing; an inclined conveyor belt 2 16 is installed at the tail end of the shredder 1, and the top end of the inclined conveyor belt 2 16 extends to the impregnation tank 2.

[0094] like Figure 1 As shown, the transition conveyor 3 includes a transition conveyor net 31 and an air-cooling frame 32, with the air-cooling frame 32 outputting towards the transition conveyor net 31; the impregnation conveyor box 22 is open towards the end of the transition conveyor 3; the vibration box 4; and the reciprocating drying frame 5 includes a drying conveyor net 51, an air-cooling frame 52, and a spiral drying box 6, with the air-cooling frame 52 outputting towards the drying conveyor net 51; the spiral drying box 6 is used for feeding and drying the dried tofu sheets.

[0095] like Figure 5The diagram shows the structure of the immersion tank 2, which includes an outer box 21 and an immersion conveyor box 22. The immersion conveyor box 22 is installed inside the outer box 21. A landing gear 23 is installed on the outer box 21, and a lifting assembly 26 is installed on the landing gear 23. The lifting assembly 26 is used to lift the immersion conveyor box 22.

[0096] The inclined conveyor belt 216 is inclined and its top is higher than the height of the outer box 21; an impregnation conveyor net 29 is installed on the impregnation conveyor box 22; the impregnation box 2 is filled with brine; an inclined pull trigger 24 is installed on the side of the impregnation conveyor box 22, and the inclined pull trigger 24 drives the impregnation conveyor net 29 to rotate.

[0097] like Figure 7 and 8 As shown, lifting lugs are installed on the impregnation conveyor box 22, and lifting shafts 25 are installed on the lifting lugs; at least two sets of parallel lifting assemblies 26 are installed on the landing gear 23, and each set of lifting assemblies 26 is respectively lifted at both ends of the corresponding lifting shaft 25; Reference Figure 12 As shown, two sets of lifting assemblies 26 are used to lift the impregnation conveyor box 22 and tilt it downward toward the transition conveyor frame 3.

[0098] like Figure 5-7 As shown, the lifting assembly 26 includes a lifting motor 261 and a winch 262. The lifting motor 261 and the winch 262 are coaxially connected. A lifting rope 263 is installed on the winch 262, and the end of the lifting rope 263 is connected to the lifting shaft 25. The bottom of the winch 262 is detachably connected to the landing gear 23. A guide wheel 264 is also installed on the landing gear 23 to constrain the direction of the lifting rope 263.

[0099] like Figure 8 As shown, the impregnation conveyor box 22 is equipped with a track groove 241 on its side, and the inclined trigger 24 includes a slider 242, which is constrained to slide within the track groove 241.

[0100] The outer end of the slider 242 is equipped with a connector 243 and a constraint 7. The connector 243 connects the slider 242 and the immersion conveyor 29; the constraint 7 connects the slider 242 and the immersion conveyor box 22. Limit switches 1 244 and 245 are respectively provided at the front and rear ends of the track groove 241 to control the tilt reset and the descent of the immersion conveyor box 22, respectively. Limit switches 1 and 2 are connected to the control cabinet through wired or wireless signal transmission, and then the control cabinet controls the action of the hoisting motor.

[0101] When the impregnation conveyor 29 is tilted at an angle greater than A, the specific angle A is related to the static friction of the slider. When the angle increases further, the slider begins to slide continuously along the track groove. The slider 242 slides in the track groove 241, causing the tortoise wires on the impregnation conveyor 29 to move towards the transition conveyor frame 3.

[0102] like Figure 8-10 As shown, the constraint member 7 includes a mounting base 71 and a rod 72. The mounting base 71 is installed in the impregnation tank 2. A column head is provided on the mounting base 71, and the column head is rotatably connected to the rod 72.

[0103] A tension spring 73 is installed at the end of rod 72 away from the column head, and one end of the tension spring 73 is constrained and fixed to rod 72; a fixed column 74 is installed on the slider 242, and a hinge joint is installed at the outer end of the fixed column 74, and rod 75 is installed on the hinge joint; the other end of the tension spring 73 is constrained and fixed to rod 75.

[0104] A support frame is installed at the bottom of the slider 242, and a load block 76 is detachably installed on the support frame.

[0105] A discharge drive and a discharge conveyor 27 are installed at the tail of the impregnation tank 2. The discharge drive drives the discharge conveyor 27 to rotate, so that the tofu skin is discharged upward.

[0106] Material plates 28 are installed at equal intervals on the discharge conveyor network 27. The material plates 28 can be detachably installed on the discharge conveyor network 27.

[0107] Lifting methods, combined with Figure 12 As shown:

[0108] a. After the tofu skin strips are soaked, the lifting assembly 26 raises the soaking conveyor box 22, causing the tofu skin strips to be removed from the brine, and stops for 2-5 minutes; then, the control cabinet controls one set of lifting assemblies 26 facing the shredder 1 to continue to rise, while the other set of lifting assemblies 26 stops rising; the lifting continues, and the soaking conveyor net 29 tilts downward toward the transition conveyor frame 3, with its height higher than the bottom height of the discharge conveyor net 27; the slider 242 drives the soaking conveyor net 29 to rotate, causing the tofu skin strips to fall onto the discharge conveyor net 27;

[0109] b. When the impregnation conveyor 29 is tilted, the slider 242 slides down. Under the action of the load block 76, the slider 242 abuts against the limit switch 244 located at the end, causing the lifting rope 263 toward the lifting assembly 26 of the shredder 1 to descend until the bottom of the two sets of lifting ropes 263 are at the same level.

[0110] c. The tension spring 73 inside the constraint member 7 pulls the slider 242 to reset along the track groove 241 toward the shredder 1;

[0111] d. A reset drive cylinder 210 can be installed inside the impregnation tank 2. The output end of the reset drive cylinder 210 is connected to the mounting base 71. When the two sets of lifting ropes 263 are at the same level again in step B, the output end of the reset drive cylinder 210 moves toward the shredder 1. When the slider 242 abuts against the limit switch 245, the two sets of lifting components 26 are controlled to descend through signal transmission until the impregnation conveyor box 22 is placed inside the impregnation tank 2.

[0112] This invention achieves staged soaking of dried tofu strips by lifting the impregnation conveyor box using a hoisting method. A set of hoisting components lifts one end of the impregnation conveyor box, tilting it, and then a diagonal pull triggers the movement of the impregnation conveyor network, moving the tofu strips forward. A slider within a constraint member moves within a track groove, triggering a limit switch, which resets the hoisting motor of the hoisting component, automatically returning the impregnation conveyor box to a horizontal position. Then, the constraint member and a reset drive cylinder cause the slider to reset and abut against a second limit switch, causing the hoisting motor to drive the hoisting rope to lower the impregnation conveyor box, achieving the reset effect. This structure enables automatic draining, tilting and unloading, and reset actions, achieving brine impregnation of the dried tofu strips.

The inclined vibration net 42 is mounted on the bottom side with a vibration spring 43 and is fixed to the fixed base 41 by the vibration spring 43. A vibration motor 44 is mounted on the inclined vibration net 42.

[0116] The inclined vibration net 42 is inclined downward from one end located near the transition conveyor 3 toward the end of the reciprocating drying rack 5.

[0117] like Figure 16 and 17 As shown, the drying conveyor network 51 has multiple layers, and a drive roller 54 is installed inside. A transmission motor 55 is installed outside the drive roller 54 to drive the corresponding drying conveyor network 51 to rotate. Each layer of the drying conveyor network 51 is driven by a set of transmission motors 55 installed in each layer to drive the corresponding drive roller to rotate. The length of the drying conveyor network 51 of the next layer is greater than the length of the drying conveyor network 51 of the previous layer, and the horizontal positions of the two ends of the drying conveyor network 51 of the next layer extend beyond the horizontal positions of the two ends of the drying conveyor network 51 of the previous layer.

[0118] like Figure 18-20As shown, the spiral drying box 6 includes a feed inlet 61, which is located at the bottom of the multi-layer drying conveyor network 51; a position fan 62 is installed on the reciprocating drying rack 5, and its output end is connected to and faces the spiral drying box 6.

[0119] The spiral drying chamber 6 is equipped with a main shaft 63 and a spiral blade 64. The output end of the position fan 62 is eccentrically set with the main shaft 63. When the position fan 62 outputs, the wind power drives the spiral blade 64 to transport the tofu strands downward.

[0120] An air chamber is provided inside the main shaft 63, and an air supply pipe 65 is installed inside the air chamber; a fixing strip 66 is provided on the side of the spiral blade 64, and an air bladder tube 67 is installed inside the fixing strip 66. An air hole 1 is provided on the side of the air bladder tube 67 facing the main shaft 63, and the air bladder tube 67 is connected to the air supply pipe 65 inside the main shaft 63; an air hole 2 is provided on the spiral drying oven 6.

[0121] The processing method of the automated line for processing sheet silk includes the following steps:

[0122] Step 1: The tofu sheets are laid flat on the inclined conveyor belt 11 and fall vertically into the cutting blade holder 12; the cutting blade 13 inside the cutting blade holder 12 cuts the tofu sheets to form tofu strips.

[0123] Step 2: The tofu skin shreds are transported onto the impregnation conveyor network 29 via the inclined conveyor belt 16. After the single batch of tofu skin shreds is cut, the conveying of the shredder 1 is paused.

[0124] Step 3: Fill the soaking tank 2 with brine beforehand and test the brine concentration. If it meets the standard, fill it with the dried tofu strips from Step 2.

[0125] The impregnation time should be controlled between 20 and 40 minutes, and the concentration range should be 1-3%.

[0126] a. After the tofu skin strips are soaked, the lifting assembly 26 raises the soaking conveyor box 22, causing the tofu skin strips to be removed from the brine, and stops for 2-5 minutes; then, the control cabinet controls one set of lifting assemblies 26 facing the shredder 1 to continue to rise, while the other set of lifting assemblies 26 stops rising; the lifting continues, and the soaking conveyor net 29 tilts downward toward the transition conveyor frame 3, with its height higher than the bottom height of the discharge conveyor net 27; the slider 242 drives the soaking conveyor net 29 to rotate, causing the tofu skin strips to fall onto the discharge conveyor net 27;

[0127] b. When the impregnation conveyor 29 is tilted, the slider 242 slides down. Under the action of the load block 76, the slider 242 abuts against the limit switch 244 located at the end, causing the lifting rope 263 toward the lifting assembly 26 of the shredder 1 to descend until the bottom of the two sets of lifting ropes 263 are at the same level.

[0128] c. The tension spring 73 inside the constraint member 7 pulls the slider 242 to reset along the track groove 241 toward the shredder 1;

[0129] d. A reset drive cylinder 210 is installed inside the impregnation tank 2. The output end of the reset drive cylinder 210 is connected to the mounting base 71. When the two sets of lifting ropes 263 are at the same level again in step B, the output end of the reset drive cylinder 210 moves toward the shredder 1. When the slider 242 abuts against the limit switch 245, the two sets of lifting components 26 are controlled to descend through signal transmission until the impregnation conveyor box 22 is placed inside the impregnation tank 2.

[0130] Step 4: The discharge conveyor 27 conveys the dried sheet wires onto the transition conveyor 31, where they are air-cooled and dehydrated via the air-cooling frame 32.

[0131] Step 5: The transition conveyor 31 drops the tofu skin onto the inclined vibrating screen 42 for vibration dehydration;

[0132] Step 6: The end of the reciprocating drying rack 5 is equipped with an inclined conveyor net 53, which is driven to the top drying conveyor net 51; it is conveyed through the multi-layer drying conveyor net 51 and dried by the air-cooled fan 56 installed on the air-cooled rack 52.

[0133] Step 7: The bottom drying conveyor 51 feeds the tofu shreds into the feed inlet 61. The feed inlet 61 is set at an angle to feed the tofu shreds onto the spiral blade 64. The position fan 62 blows the spiral blade 64 to rotate, causing the tofu shreds on the spiral blade 64 to roll off until they reach the bottom discharge port.

[0134] Simultaneously, gas is introduced into the air supply pipe 65 inside the main shaft 63 to ensure the position of the tofu skin strands;

[0135] Complete the processing of thousand-sheet silk.

[0136] This invention employs a quadruple air-cooling system—including a first air-cooled fan, a vibrating chamber, a second air-cooled fan, and a positional fan—to achieve thorough drying of the tofu skin strands. The tofu skin strands are driven by a spiral blade within the spiral drying chamber. This spiral blade is rotated by an eccentric positional fan, and the air is blown inwards through the air supply pipes and air bladder pipes on the main shaft. This causes the tofu skin strands to gather outside the main shaft, facilitating thorough drying and achieving a dual effect of rotational feeding and drying.
