Description

Technical Field

[0001] The invention relates to the technical field of food processing, and in particular to a production line and a preparation method for preparing high-ductility snow skin. Background Art

[0002] Snow skin cakes, also known as snow skin snacks, specifically refer to cakes made with glutinous rice flour, wheat starch, etc. as the cake crust. The crust is transparent and crystal-like, and it is soft and sticky. Snow skin cakes do not need to be baked. Compared with the high-fat and high-sugar characteristics of traditional baked cakes, they are more in line with the requirements of modern people's healthy diet.

[0003] The Chinese invention patent application with publication number CN112401127A discloses a snowy mooncake skin and a preparation method thereof, which can produce snowy skin for preparing snowy pastries. In the process of preparing snowy pastries, the snowy skin needs to maintain a certain thickness when wrapping the fillings to prevent the fillings from breaking out of the skin. However, for the prepared snowy pastries, the thicker the skin, the greater the proportion of stimulation of the skin to the taste buds relative to the fillings, which leads to a worse taste. For pastries, whether the skin is thin and the fillings are full is an important taste evaluation criterion.

[0004] How to upgrade and improve the preparation process of snow skin to make it highly ductile and less likely to break when wrapping fillings. We have conducted experiments combining various ingredients with snow skin and found that when lotus root silk is combined with snow skin, the ductility of the snow skin is significantly improved. Lotus root silk can give the snow skin the excellent characteristics of "thin and not easy to break", and the main components of lotus root silk are natural substances such as cellulose and pectin, so the snow skin produced is greener and healthier.

[0005] However, the current method of extracting lotus root silk is mainly through manual extraction. How to realize the extraction of lotus root silk and the combination of lotus root silk and ice skin in production equipment and production process has become a technical problem that needs to be overcome in the improvement and upgrading of ice skin. To this end, we proposed a production line and preparation method for preparing high-ductility ice skin. Summary of the invention

[0007] To achieve the above object, the present invention adopts the following technical solution: A production line for preparing highly ductile ice skin, including a conveyor belt, at which an lotus root fiber skin covering unit is provided. The lotus root fiber skin covering unit includes a stalk breaking device for breaking the lotus root stalk and a fiber drawing device for drawing out the lotus root fibers. The stalk breaking device and the fiber drawing device are respectively arranged on the left and right sides of the conveyor belt. At the conveyor belt, a fiber hooking mechanism for hooking the lotus root fibers and adhering them to the ice skin dough is also provided, and at the conveyor belt, a rolling cylinder for rolling the ice skin dough adhered with the lotus root fibers is provided. The stalk breaking device includes a first bottom plate, a support plate, and a stalk mounting plate. At the front and rear sides of the stalk mounting plate, a stalk breaking positioning mechanism and a pressing and clamping mechanism are respectively provided. At the stalk mounting plate, a number of straight pipe fittings for inserting the lotus root stalks are fixedly arranged. The left and right sides of the stalk mounting plate are movably arranged at the support plate, and the support plate is translationally slidably arranged on the first bottom plate. A lifting plate displacement mechanism is provided below the stalk mounting plate. After the stalk mounting plate is tilted downward to reserve a section of the lotus root stalk to be broken, the lifting plate displacement mechanism lifts the stalk mounting plate and simultaneously drives the stalk mounting plate to move closer to the fiber hooking mechanism. The fiber drawing device includes a moving frame, and at the moving frame, a stalk receiving seat for cooperating with the stalk breaking positioning mechanism is provided.

[0008] Further elaborating, both sides of the stalk mounting plate are provided with a first rod foot part and a second rod foot part. A first driving rod is connected between the second rod foot parts on both sides of the stalk mounting plate. At the support plate, an inclined rod path for cooperating with the first rod foot part and a horizontal rod path for cooperating with the second rod foot part are provided.

[0009] Further elaborating, the lifting plate displacement mechanism includes a first driving cylinder, an intermediate transmission member, and a hinge shaft. The hinge shaft is fixedly inserted at the support plate, the intermediate transmission member is rotatably arranged at the hinge shaft, one end of the intermediate transmission member is provided with a hinge part hinged to the telescopic rod of the first driving cylinder, and the other end of the intermediate transmission member is provided with a fork part for driving the first driving rod of the stalk mounting plate.

[0010] Further elaborating, the stalk breaking positioning mechanism includes a stalk breaking positioning member, a second driving rod, a hinge arm, and a fixed seat arranged above the stalk mounting plate. The stalk breaking positioning member is hinged to the fixed seat. An electric cylinder is provided at the fixed seat, the telescopic rod of the electric cylinder is hinged to the second driving rod, the second driving rod is hinged to one end of the hinge arm, the other end of the hinge arm is hinged to the stalk breaking positioning member, and the stalk breaking positioning member is provided with a positioning edge.

[0011] Further elaborating, both sides of the stub shaft seat of the silk extraction device are respectively hinged to both ends of the moving frame. The stub shaft seat is provided with a stub shaft groove, and the inner groove width D1 of the stub shaft groove is greater than the outer width D2 of the stub folding positioning member. The moving frame drives the stub shaft seat to move below the stub folding positioning member, and the electric cylinder drives the stub folding positioning member to flip towards the stub shaft seat, thereby breaking the lotus root stalk segments extending from the stub shaft plate. The broken lotus root stalk segments are inclined and placed in the stub shaft groove of the stub shaft seat.

[0012] Further elaborating, the silk extraction device includes a second bottom plate. The moving frame is horizontally arranged at the second bottom plate. Second driving cylinders are arranged on both sides of the moving frame, and the telescopic rods of the second driving cylinders are hinged to the stub shaft seat. The second bottom plate is provided with a stub shaft opening below the stub shaft seat, and a receiving hopper is arranged at the stub shaft opening.

[0013] Further elaborating, the silk hook mechanism includes a first rotating shaft, a second rotating shaft, and a stepping motor. The first rotating shaft and the second rotating shaft are rotatably arranged below the conveyor belt. The stepping motor is connected to the first rotating shaft. First swing rods are installed on both sides of the first rotating shaft, and second swing rods are installed on both sides of the second rotating shaft. The first swing rods and the second swing rods are equal in length and parallel to each other. A silk hook spring wire for hooking the lotus root silk is connected between the first swing rod and the second swing rod on the same side of the conveyor belt. Burrs for hooking the lotus root silk are arranged on the surface of the silk hook spring wire.

[0014] Further elaborating, the pressing and clamping mechanism includes a lifting pressing rod. Lifting driving cylinders are arranged at both ends of the lifting pressing rod. A number of elastic pressing rings are sleeved on the lifting pressing rod at equal intervals, and the elastic pressing rings are in the shape of cams.

[0015] A preparation method for preparing high-ductility ice skin, based on the above production line, includes the following steps: S1. The lifting plate displacement mechanism at the stalk folding device drives the stub shaft plate to deflect and tilt downward, and drives the stub shaft plate and the support plate to move away from the conveyor belt at the same time. The electric cylinder of the stub folding positioning mechanism drives the stub folding positioning member to deflect downward, so that the stub folding positioning member is parallel to the stub shaft plate. At this time, the downwardly inclined stub shaft plate is in a state where lotus root stalks can be inserted. S2. Workers insert lotus root stalks with the surface silt cleaned at each straight pipe section of the stub shaft plate. The lengths of the lotus root stalks inserted at the straight pipe sections are equal. The lotus root stalk segments to be broken extending from the front side of the stub shaft plate are located below the stub folding positioning member, and the front ends of the lotus root stalk segments to be broken abut against the positioning edge of the stub folding positioning member, so that the same length of lotus root stalk segments to be broken are reserved for each lotus root stalk. S3. The lifting pressure rod of the pressing and clamping mechanism descends, and the elastic pressing ring at the lifting pressure rod presses against the lotus root stalk. Subsequently, the lifting plate displacement mechanism at the stalk breaking device drives the stalk loading plate to lift upward, and drives the stalk loading plate and the support plate to approach the conveyor belt simultaneously; S4. The moving frame of the silk extraction device drives the stalk receiving seat to cross over the conveyor belt and approach the stalk breaking device. The stalk receiving seat moves to the lower part of the stalk breaking positioning part, and the electric cylinder drives the stalk breaking positioning part to slowly flip towards the stalk receiving seat, thereby breaking the stalk segment of the lotus root stalk extending out at the stalk loading plate. The broken stalk segment of the lotus root stalk leans obliquely in the stalk receiving groove of the stalk receiving seat; S5. The moving frame of the silk extraction device drives the stalk receiving seat to return to the other side of the conveyor belt. The broken stalk segment of the lotus root stalk in the stalk receiving seat pulls out lotus root silk during the translation of the stalk receiving seat; S6. The conveyor belt conveys the strip-shaped glutinous rice dough to the front of the rolling cylinder, and at this time the glutinous rice dough is in a static state; S7. The first swing rod and the second swing rod of the silk hooking mechanism drive the silk hooking spring wire. The silk hooking spring wires on both sides of the conveyor belt intercept the lotus root silk between the stalk loading plate and the stalk receiving seat. The silk hooking spring wire drives the lotus root silk and covers the lotus root silk on the surface of the strip-shaped glutinous rice dough, and the glutinous rice dough adheres to the lotus root silk; S8. The conveyor belt drives the glutinous rice dough to translate towards the rolling cylinder, and the rolling cylinder rolls the strip-shaped glutinous rice dough, so that the lotus root silk is completely incorporated into the glutinous rice dough. The strip-shaped glutinous rice dough is rolled into a thin skin shape by the rolling cylinder, thereby making high-ductility glutinous rice skin.

[0016] The beneficial effects of the present invention are as follows: The present invention discloses a production line and a preparation method for preparing high-ductility glutinous rice skin, realizing the processes of drawing, taking, and finally fusing the lotus root silk with the glutinous rice dough to make high-ductility glutinous rice skin. The prepared glutinous rice skin has lotus root silk embedded therein, significantly improving the ductility of the glutinous rice skin. The prepared glutinous rice skin has the excellent characteristics of "thin and not easy to break". Description of the Drawings

Detailed implementation manners

[0029] To make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings.

[0030] Combined with the attached Figure 1and appendix Figure 2 As shown, a production line for preparing highly ductile ice skin includes a conveyor belt 10. At the conveyor belt 10, there is a lotus root fiber skin covering unit. The lotus root fiber skin covering unit includes a frame 80, a stalk breaking device 20 for breaking lotus root stalks 60, and a silk extracting device 30 for extracting lotus root fibers. Specifically, the frame 80 is disposed under the conveyor belt 10. The stalk breaking device 20 and the silk extracting device 30 are respectively disposed on the left and right sides of the conveyor belt 10. The stalk breaking device 20 is installed on the left side of the frame 80, and the silk extracting device 30 is installed on the right side of the frame 80; At the conveyor belt 10, there is also a silk hooking mechanism 40 for hooking the lotus root fibers 63 and adhering the lotus root fibers 63 to the ice skin dough. At the conveyor belt 10, there is a rolling cylinder 50 for rolling the ice skin dough 70 adhered with the lotus root fibers 63; The stalk breaking device 20 includes a first bottom plate 21, a support plate 22, and a stalk loading plate 23. On the front and rear sides of the stalk loading plate 23, there are respectively a stalk breaking positioning mechanism 24 and a pressing and clamping mechanism 25. A number of straight pipe fittings 233 for inserting lotus root stalks are fixedly arranged at the stalk loading plate 23. A number of straight pipe fittings 233 are welded to the stalk loading plate 23 in a side-by-side and flat-laying manner. The material of the straight pipe fittings 233 is preferably food-grade stainless steel, and the inner pipe diameter of the straight pipe fittings 233 is 1.0 mm - 1.5 mm larger than the maximum outer diameter of the lotus root stalks optimally.

[0031] Support plates 22 are provided on both sides of the stalk loading plate 23. The left and right sides of the stalk loading plate 23 are movably arranged at the support plates 22. The support plates 22 are specifically arranged to be translationally slidable on the first bottom plate 21 through linear slide rails. A lifting plate displacement mechanism 26 is provided below the stalk loading plate 23. As shown in the appendix Figure 4 shown, after the stalk loading plate 23 is tilted downward to reserve a lotus root stalk segment 61 to be broken, as shown in the appendix Figure 5 shown, the lifting plate displacement mechanism 26 lifts the stalk loading plate 23 and simultaneously drives the stalk loading plate 23 to move closer to the silk hooking mechanism 40. The silk extracting device 30 includes a moving frame 31. At the moving frame 31, there is a stalk receiving seat 32 for cooperating with the stalk breaking positioning mechanism 24.

[0032] Before breaking the lotus root stalk 60 to extract silk, a certain length of lotus root stalk segment 61 to be broken needs to be reserved on the lotus root stalk 60 first. The length of the lotus root stalk segment 61 to be broken accounts for at least one-fourth of the total length of the lotus root stalk 60. In order to avoid interference between the lotus root stalk segment 61 to be broken and the conveyor belt 10, a certain distance needs to be maintained between the stalk loading plate 23 and the conveyor belt 10. In addition, since the lotus root fibers will ultimately adhere to the ice skin dough on the conveyor belt 10, the length of the lotus root fibers 63 cannot be much longer than the width of the conveyor belt 10, otherwise the lotus root fibers are prone to a loose state of sagging in the middle, resulting in the subsequent silk hooking mechanism 40 being unable to smoothly hook the lotus root fibers 63. Therefore, when the stalk loading plate 23 is in a downward tilted state, a certain distance needs to be maintained between it and the conveyor belt 10. When the stalk loading plate 23 is in an upward lifted state, it should be close to the conveyor belt 10.

[0033] To solve this technical problem, our side has adopted the structural design of the lifting plate displacement mechanism 26. When a certain length of the lotus stalk segment 61 to be folded needs to be reserved on the lotus stalk 60, the stem loading plate 23 tilts downward and maintains a certain distance from the conveyor belt 10 to facilitate the extension of the lotus stalk segment 61 to be folded from the stem loading plate 23. When it is necessary to pull out the lotus silk, the lifting plate displacement mechanism 26 drives the stem loading plate 23 to lift upward and approach the conveyor belt 10 at the same time.

[0034] On both sides of the stem loading plate 23, there are first rod feet 231 and second rod feet 232. A first driving rod 234 is connected between the second rod feet 232 on both sides of the stem loading plate 23. At the support plate 22, there are inclined rod channels 221 that cooperate with the first rod feet 231 and horizontal rod channels 222 that cooperate with the second rod feet 232.

[0035] The lifting plate displacement mechanism 26 includes a first driving cylinder 261, an intermediate transmission member 262, and a hinge shaft 263. The hinge shaft 263 is fixedly inserted at the support plate 22. The intermediate transmission member 262 is rotatably arranged at the hinge shaft 263. One end of the intermediate transmission member 262 is provided with a hinge portion 2621 that is hinged to the telescopic rod of the first driving cylinder 261. The cylinder body of the first driving cylinder 261 is hinged to the first bottom plate 21. The other end of the intermediate transmission member 262 is provided with a fork portion 2622 for driving the first driving rod 234 of the stem loading plate 23.

[0036] Combined with the attached Figure 2 and the attached Figure 11 As shown, when the telescopic rod of the first driving cylinder 261 extends, the first driving cylinder 261 drives the intermediate transmission member 262. The intermediate transmission member 262 deflects clockwise around the hinge shaft 263. The fork portion of the intermediate transmission member 262 drives the first driving rod 234. The first driving rod 234 drives the second rod foot 232 of the stem loading plate 23 to move to the right end position of the horizontal rod channel 222 of the support plate 22. The first rod foot 231 of the stem loading plate 23 simultaneously moves to the lower end position of the inclined rod channel 221 of the support plate 22, thereby driving the stem loading plate 23 to deflect downward and tilt. As the telescopic rod of the first driving cylinder 261 continues to extend, the stem loading plate 23 together with the support plate 22 moves away from the conveyor belt 10, so a certain distance needs to be maintained between them and the conveyor belt 10. At this time, the downwardly tilted stem loading plate 23 is in a state where the lotus stalk 60 can be inserted.

[0037] Combined with the attached Figure 2 and the attached Figure 5As shown, when the telescopic rod of the first driving cylinder 261 retracts, the first driving cylinder 261 drives the intermediate transmission member 262. The intermediate transmission member 262 rotates counterclockwise around the hinge shaft 263. The fork portion 2622 of the intermediate transmission member 262 drives the first driving rod 234. The first driving rod 234 drives the second rod foot portion 232 of the stem loading plate 23 to move to the left end position of the horizontal rod path 222 of the support plate 22. At the same time, the first rod foot portion 231 of the stem loading plate 23 moves to the upper end position of the inclined rod path 221 of the support plate 22, thereby driving the stem loading plate 23 to rotate upward and lift. As the telescopic rod of the first driving cylinder 261 continues to retract, the stem loading plate 23 and the support plate 22 together move closer to the conveyor belt 10, so that when pulling out lotus root silk, the stem loading plate 23 and the conveyor belt 10 are at a relatively close distance.

[0038] The lifting plate displacement mechanism 26 adopts a clever structural design of combining the first driving cylinder 261 with the intermediate transmission member 262 and the hinge shaft 263, which can drive the stem loading plate 23 to rotate downward and tilt away from the conveyor belt 10, and when the stem loading plate 23 rotates upward and lifts, it can also move closer to the conveyor belt 10.

[0039] As shown in the appendix Figure 4 As shown, the broken stem positioning mechanism 24 includes a broken stem positioning member 241, a second driving rod 242, a hinge arm 243, and a fixed seat 244 disposed above the stem loading plate 23. The broken stem positioning member 241 is hinged to the fixed seat 244. An electric cylinder 245 is provided at the fixed seat 244. The telescopic rod of the electric cylinder 245 is hinged to the second driving rod 242. The second driving rod 242 is hinged to one end of the hinge arm 243. The other end of the hinge arm 243 is hinged to the broken stem positioning member 241. The broken stem positioning member 241 is provided with a positioning edge 2411.

[0040] Combined with the appendix Figure 1 and the appendix Figure 5 As shown, the pressing and clamping mechanism 25 includes a lifting pressing rod 251. Lifting driving cylinders 253 are provided at both ends of the lifting pressing rod 251. A number of elastic pressing rings 252 are sleeved on the lifting pressing rod 251 at equal intervals. The elastic pressing rings 252 are in the shape of cams.

[0041] As shown in the appendix Figure 5 As shown, both sides of the stem receiving seat 32 of the silk extraction device 30 are respectively hinged to both ends of the moving frame 31. The stem receiving seat 32 is provided with a stem receiving groove 321. The inner groove width D1 of the stem receiving groove 321 is greater than the outer width D2 of the broken stem positioning member 241. The moving frame 31 drives the stem receiving seat 32 to move below the broken stem positioning member 241. The electric cylinder 245 drives the broken stem positioning member 241 to flip towards the stem receiving seat 32, and then breaks the lotus root stem section extending from the stem loading plate 23. The broken lotus root stem section 62 is inclined and placed in the stem receiving groove 321 of the stem receiving seat 32.

[0042] The force for breaking the lotus root stalk should not be too large to avoid some lotus root filaments being instantly broken due to excessive force. Therefore, only the electric cylinder 245 can be used to slowly drive the stalk-breaking positioning member 241 to flip towards the stalk-receiving seat 32. A positioning edge 2411 is provided below the stalk-breaking positioning member 241. During the process of breaking the lotus root stalk, the positioning edge 2411 of the stalk-breaking positioning member 241 can play a role in supporting the broken lotus root stalk segment to the stalk-receiving seat 32. As the stalk-receiving seat 32 slowly flips, the broken lotus root stalk segment 62 is pushed into the stalk-receiving groove 321 of the stalk-receiving seat 32 by the stalk-breaking positioning member 241, thus ensuring that the stalk-receiving seat 32 can successfully receive the broken lotus root stalk segment 62. In addition, it should be noted that an electric cylinder 245 must be selected here, and a conventional cylinder cannot achieve the technical effect of slowly flipping the stalk-breaking positioning member 241 towards the stalk-receiving seat 32.

[0043] The stalk-breaking positioning member 241 not only plays a limiting role when inserting the lotus root stalks 60, making the front ends of the inserted lotus root stalks 60 flush with each other, and thus leaving the same length of the to-be-broken lotus root stalk segments 61 for each lotus root stalk, solving the problem of multi-root lotus root stalk insertion and limiting; but also can break the lotus root stalks, and cooperate with the stalk-receiving seat 32 to push the broken lotus root stalk segments 62 into the stalk-receiving groove 321 of the stalk-receiving seat 32, solving the problem of how to break and draw the silk from multiple lotus root stalks simultaneously.

[0044] Combined with the attached Figure 5 As shown, the silk-drawing device 30 includes a second bottom plate 33. The moving frame 31 is horizontally arranged at the second bottom plate 33. Second driving cylinders 34 are provided on both sides of the moving frame 31. The telescopic rods of the second driving cylinders 34 are hinged to the stalk-receiving seat 32. A stalk-inverting opening 331 is opened in the second bottom plate 33 below the stalk-receiving seat 32, and a receiving hopper 35 is provided at the stalk-inverting opening 331.

[0045] The moving frame 31 is specifically driven by a driving motor 36 combined with a ball screw pair 37. The driving motor 36 is specifically a servo motor. The driving motor 36 can drive the moving frame 31 to slowly translate through the ball screw pair 37, so that the broken lotus root stalk segment at the stalk-receiving seat 32 slowly moves away from the lotus root stalks at the stalk-loading plate 23, which can not only slowly draw out the lotus root silk 63, effectively avoiding the lotus root silk 63 from being broken, but also prevent the situation that the broken lotus root stalk segment 62 at the stalk-receiving seat 32 falls backward. Through experiments, the best silk-drawing effect is achieved when the translation speed of the moving frame 31 is less than or equal to 0.005 m / s.

[0046] Combined with the attached Figure 1 、attached Figure 8 and attached Figure 9As shown, the silk-hooking mechanism 40 includes a first rotating shaft 41, a second rotating shaft 42, and a stepping motor 45. The first rotating shaft 41 and the second rotating shaft 42 are rotatably arranged below the conveyor belt 10. Specifically, the first rotating shaft 41 and the second rotating shaft 42 are synchronously rotated through a synchronous belt. The stepping motor 45 is connected to the first rotating shaft 41. First swing rods 43 are installed on both sides of the first rotating shaft 41, and second swing rods 44 are installed on both sides of the second rotating shaft 42. The first swing rods 43 and the second swing rods 44 are equal in length and parallel to each other. A silk-hooking spring wire 46 for hooking the lotus root filaments 63 is connected between the first swing rods 43 and the second swing rods 44 on the same side of the conveyor belt 10. Burrs for hooking the lotus root filaments 63 are provided on the surface of the silk-hooking spring wire 46.

[0047] The silk-hooking mechanism 40 synchronously drives the silk-hooking spring wire 46 to move up and down in a horizontal state through the mutually parallel first swing rods 43 and second swing rods 44, so as to intercept the lotus root filaments 63 between the silk-hooking spring wires 46 on both sides of the conveyor belt 10 and the loading plate 23 and the stub stalk receiver 32. After the silk-hooking spring wire 46 intercepts the lotus root filaments, the stepping motor 45 continues to drive the first swing rod 43 to deflect through the first rotating shaft 41, and then covers the lotus root filaments 63 on the surface of the strip-shaped glutinous rice dough 70. Since the lotus root filaments themselves have a certain viscosity, when the lotus root filaments 63 cover the surface of the strip-shaped glutinous rice dough 70, the lotus root filaments 63 will adhere to the surface of the glutinous rice dough 70 at the same time. The silk-hooking mechanism 40 directly realizes the process from intercepting the lotus root filaments to covering the lotus root filaments on the surface of the strip-shaped glutinous rice dough, thus solving the technical problems of the extraction of lotus root filaments and how the lotus root filaments are combined with the glutinous rice dough.

[0048] A preparation method for preparing high-ductility glutinous rice dough based on the above production line includes the following steps: S1. Referring to Figure 1 and Figure 2 As shown, the lifting plate displacement mechanism 26 at the stalk-breaking device 20 drives the loading plate 23 to deflect downward and incline, and drives the loading plate 23 and the support plate 22 to move away from the conveyor belt 10 at the same time. The electric cylinder 245 of the stalk-breaking positioning mechanism 24 drives the stalk-breaking positioning member 241 to deflect downward, so that the stalk-breaking positioning member 241 is parallel to the loading plate 23. At this time, the downward-inclined loading plate 23 is in a state where the lotus root stalks 60 can be inserted; S2. Referring to Figure 3 As shown, the staff inserts the lotus root stalks 60 with the surface silt cleaned at each straight pipe member 233 of the loading plate 23. The lengths of the lotus root stalks 60 inserted at the straight pipe members 233 are equal. The to-be-broken lotus root stalk segments 61 protrude from the front side of the loading plate 23. The to-be-broken lotus root stalk segments 61 are located below the stalk-breaking positioning member 241, and the front ends of the to-be-broken lotus root stalk segments 61 abut against the positioning edge 2411 of the stalk-breaking positioning member 241, so that the same length of to-be-broken lotus root stalk segments 61 are reserved for each lotus root stalk; S3. Referring to Figure 4As shown, the lifting and pressing rod 251 of the pressing and clamping mechanism 25 descends, and the elastic pressing ring 252 at the lifting and pressing rod 251 presses against the lotus stem 60. Subsequently, as shown in the appendix Figure 5 As shown, the lifting plate displacement mechanism 26 at the stem folding device 20 drives the stem loading plate 23 to lift upward, and drives the stem loading plate 23 and the support plate 22 to approach the conveyor belt 10 simultaneously; S4. Combining with the appendix Figure 6 As shown, the moving frame 31 of the silk extraction device 30 drives the stem receiving seat 32 to cross over the conveyor belt 10 and approach the stem folding device 20. The stem receiving seat 32 moves to the lower side of the stem folding positioning member 241. As shown in the appendix Figure 7 As shown, the electric cylinder 245 drives the stem folding positioning member 241 to slowly flip towards the stem receiving seat 32, thereby breaking the to-be-folded lotus stem section 61 extending from the stem loading plate 23. The broken lotus stem section 62 leans obliquely in the stem receiving groove 321 of the stem receiving seat 32; S5. Combining with the appendix Figure 8 As shown, the moving frame 31 of the silk extraction device 30 drives the stem receiving seat 32 to return to the other side of the conveyor belt 10. The broken lotus stem section in the stem receiving seat 32 pulls out the lotus silk 63 during the translation of the stem receiving seat 32; S6. The conveyor belt 10 conveys the strip-shaped glutinous rice dough 70 to the front of the rolling cylinder 50. At this time, the glutinous rice dough 70 is in a static state; S7. Combining with the appendix Figure 9 As shown, the first swing rod 43 and the second swing rod 44 of the silk hooking mechanism 40 drive the silk hooking spring wire 46. The silk hooking spring wires 46 on both sides of the conveyor belt 10 intercept the lotus silk 63 between the stem loading plate 23 and the stem receiving seat 32. The silk hooking spring wire 46 drives the lotus silk 63 and covers the lotus silk 63 on the surface of the strip-shaped glutinous rice dough 70. The glutinous rice dough 70 adheres to the lotus silk 63. At this time, as shown in the appendix Figure 10 As shown, the height position of the silk hooking spring wire 46 is lower than the upper surface of the strip-shaped glutinous rice dough 70; S8. Finally, the conveyor belt 10 drives the glutinous rice dough 70 to translate towards the rolling cylinder 50. The rolling cylinder 50 rolls the strip-shaped glutinous rice dough 70, so that the lotus silk 63 is completely incorporated into the glutinous rice dough 70. The strip-shaped glutinous rice dough 70 is rolled into a thin skin shape by the rolling cylinder 50, thereby making a highly ductile glutinous rice skin.

[0049] After the silk intercepting mechanism 40 intercepts the lotus root silk 63 between the stem loading plate 23 and the stem receiving seat 32, the second driving cylinder 34 drives the stem receiving seat 32 to tilt backward, and the stem receiving seat 32 pours the lotus root stem segment 62 at its position into the material receiving hopper 35 through the stem reversing port 331. Subsequently, the lifting plate displacement mechanism 26 drives the stem loading plate 23 to deflect and tilt downward, and drives the stem loading plate 23 and the support plate 22 to move away from the conveyor belt 10 at the same time. The electric cylinder 245 of the stem folding and positioning mechanism 24 drives the stem folding and positioning member 241 to deflect downward, so that the stem folding and positioning member 241 is parallel to the stem loading plate 23. The clamping mechanism 25 releases the lotus root stem 60, and the lotus root stem 60 slides down along the positioning edge 2411 of the stem folding and positioning member 241, leaving the next group of lotus root stem segments 61 to be folded reserved again, and repeating the operations of steps S3 to S8.

[0050] In the actual production process, this production line can be used to incorporate lotus root silk into the glutinous rice dough for ice skin multiple times, so that the ice skin contains multiple layers of lotus root silk with different orientations, making the ice skin have multi-directional ductility. For the obtained ice skin, lotus root silk is embedded therein, and the lotus root silk can significantly improve the ductility of the ice skin. When wrapping the filling, although the ice skin is thin, under the action of the lotus root silk, the ice skin is not easily broken by the filling. The made ice skin pastry has a thin skin and a full filling, and has an excellent edible taste.
