Description

Technical Field

[0001] The invention belongs to the field of starch product food production, and in particular relates to an extrusion type rice noodle dough spreading mechanism. Background Art

[0002] During the production process of starch products (especially vermicelli), the prepared slurry is injected into the slurry storage tank, and the slurry is wrapped and brought out to form a layer through a shaping roller in cooperation with the slurry storage tank by utilizing the viscosity of the slurry, and then sent to the conveyor steel belt, and sent to the steaming process for steaming and cooling and shaping (for example, application number CN2016206543078, sweet potato vermicelli rapid aging device). In this process, since the slurry is not uniform (that is, the dilution and viscosity of each part of the slurry are different), the amount of slurry wrapped on the shaping roller at every moment will be quite different, resulting in uneven thickness of the vermicelli produced. On the other hand, this slurry spreading method is difficult to produce efficiently, and the excessive speed of the shaping roller will further lead to uneven slurry wrapping.

[0003] The principle of the extruder can be applied to the above-mentioned slurry spreading work. The slurry spreading speed can be changed by changing the extrusion pressure and speed. However, the traditional extruder cannot be directly applied to this work. This is because when the extruder extrude the material, the material has been shaped, and its shape is determined by the extrusion port. In the production process of vermicelli, slurry spreading is merely to distribute the slurry to the conveyor steel belt. The conveyor steel belt carries the slurry and is successively steamed in a steamer and cooled in a refrigerator before being shaped (for details, please refer to CN201810738509.4, straight vermicelli processing machine and processing method proposed by the applicant). That is, it is still in a slurry state when extruded. In the production line, in order to ensure production efficiency, the width of vermicelli in a production line can reach 2-3m or more. The slurry extruded by the extruder must exist. Along the width direction of the extrusion port, the extrusion amount of the middle part is much larger than the extrusion amount on both sides (the pump cannot achieve the same large width as the extrusion port, it can only be a conventional pump and aligned with the middle of the extrusion port, such as Figure 2 ), so the extruder needs to be improved to make the slurry spreading effect more uniform.

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] As attached Figure 1-2 As shown, an extrusion-type dough-spreading quantitative mechanism comprises a pump 1, which may be a conventional liquid pump on the market. The discharge port of the pump 1 is connected to a distribution box 2 through a pipeline, and the distribution box 2 comprises a storage section 3, a guide section 4, and a discharge section 5 which are fixedly connected in sequence, wherein: The material storage section 3 is connected to the discharge port of the pump 1 through at least two distribution pipelines 31. At least two distribution pipelines 31 are arranged at intervals on the material storage section 3 to make the feeding in the longer distribution box 2 more uniform. The guide section 4 has guide holes 41 arranged at intervals along the length direction of the distribution box 2, one end of the guide hole 41 is connected to the material storage section 3, and the other end of the guide hole 41 is connected to the material discharge section 5; The discharging section 5 has a discharging port 51 at one end thereof, and at least two adjusting mechanisms for adjusting the size of the discharging port 51 are arranged along the length direction of the discharging port 51 .

[0021] In detail, the storage section 3, the guide section 4, and the discharge section 5 can be produced in sections, and flanges are fixed at the ends. The components are abutted against each other through flanges and fixed by bolts, and sealing rings or sealing welds can be further provided.

[0022] Preferably, both the material storage section 3 and the material discharge section 5 are variable diameter structures whose width decreases from top to bottom, and may be conical or funnel-shaped.

[0023] like Figure 1This extrusion-type rice noodle spreading mechanism is arranged in the rice noodle production line of the prior art. For details, see CN201810738509.4 proposed by the applicant, a straight vermicelli processing machine and a processing method. The feed port of the pump 1 is connected to the rice noodle production stirring mechanism through a pipeline. Below the distribution box 2 is a steel belt that continuously moves in a cycle, and in front of it is a long steamer. A cooling box is arranged behind the steamer. When the rice noodle falls onto the steel belt, it is still in a slurry state. It is initially shaped by steaming in the steamer and completely shaped by cooling in the cooling box.

[0024] Furthermore, the discharge port of the pump 1 is connected to one end of the main pipeline 11 , the other end of the main pipeline 11 is connected to one end of at least two distribution pipelines 31 , and the other end of the distribution pipeline 31 is connected to the material storage section 3 .

[0025] Furthermore, in order to produce rice noodle sheets of 2-3m or even wider, the distribution box also needs such a width. However, due to the limitation of the width of the pump 1, the slurry entering the storage section 3 through the distribution pipeline 31 must have a higher pressure and flow rate in the distribution pipeline 31 closer to the middle. This is because the distribution pipeline 31 closer to the outside is longer and has a larger elbow angle, so the flow rate and pressure loss are greater. In order to make the discharge more uniform, the distribution pipeline 31 needs to be adjusted.

[0026] As a solution, if Figure 3 As shown, the farther the connection between the distribution pipeline 31 and the material storage section 3 is from the center line of the material storage section 3, the greater the maximum flow rate of the distribution pipeline 31, that is, the further the connection between the distribution pipeline 31 and the material storage section 3 is set outward, the larger the distribution pipeline 31 is used.

[0027] As another option, Figure 4 As shown, the farther away from the center line of the material storage section 3, the denser the distribution pipelines 31 connected to the material storage section 3, that is, the closer to the two side edges of the material storage section 3, the smaller the distance between the connection between the distribution pipeline 31 and the material storage section 3.

[0028] Through the above scheme, the slurry entering different positions of the storage section 3 is homogenized as a whole, thereby improving the situation of excessive pressure in the middle.

[0029] Further, as attached Figure 5 As shown, the guide hole 41 is a variable diameter hole, and the cross-sectional area of ​​the guide hole 41 decreases from the material storage section 3 to the material discharge section 5; the axes of all the guide holes 41 are parallel to each other.

[0030] Preferably, the guide holes 41 are hole structures arranged in an array along the length direction of the distribution box 2 on the overall closed guide section 4. The purpose of the above two features is that the pressure and flow direction of the slurry entering the storage section 3 from the distribution pipeline 31 are diffused downward in a wave-like manner, and the pressures formed at the outlet of each distribution pipeline 31 interfere with each other, which is not conducive to the stability and uniformity of the final discharge. Therefore, the guide holes 41 are used to guide the flow direction on the one hand, and on the other hand, the variable diameter structure is used to converge and further adjust the pressure.

[0031] The above structure mainly plays the role of regulating pressure and homogenizing the feeding condition of up to 2-3m or even longer, but in actual discharging, the above structure still cannot make the discharging completely uniform, and there may still be a situation where the pressure in the middle is higher or the pressure on both sides is higher, resulting in uneven discharging.

[0032] Therefore, further, an extrusion port adjustment structure of an extrusion type noodle spreading machine is proposed, including a distribution box body 2, an outlet 51 is arranged at the end of the distribution box body 2, and the outlet 51 includes a bottom plate 52 and an adjustment plate 53. The outlet 51 is formed between the bottom plate 52 and the adjustment plate 53, and at least two adjustment mechanisms are arranged at intervals along the length direction of the adjustment plate 53. The adjustment mechanism is used to cooperate with the adjustment plate 53 to change the distance between the part of the adjustment plate 53 corresponding to the adjustment mechanism and the bottom plate 52.

[0033] Through the adjustment mechanism of the discharge port 51, the size of the corresponding discharge port 51 is adjusted to change the flow rate at that location, so that the overall discharge can be more uniform. As a basic solution, Figure 6 As shown, the base plate 52 is a U-shaped plate, the adjustment plate 53 is arranged on the top of the base plate 52, the base plate 52 is fixedly connected to the portal frame 54, and the two sides of the base plate 52 are respectively fixedly connected to the two ends of the portal frame 54, and the portal frame 54 is provided with adjustment mechanisms at intervals, and the adjustment mechanism is a tightening screw 55, and the end of the tightening screw 55 faces the adjustment plate 53. The tightening screw 55 is provided with a locking nut 56, and the tightening screw 55 is locked relative to the portal frame 54 by one or two locking nuts 56.

[0034] In detail, the bottom plate 52 can be an integral structure with the discharge section 5, and the adjusting plate 53 can be hingedly connected to the discharge section 5 at the top by a hinge, and the two are expanded by the flow of slurry during operation; or the two ends of the adjusting plate 53 are fixedly connected to the two ends of the U-shaped structure of the bottom plate 52 to form an integral U-shaped structure, and the maximum opening amount of the discharge port 51 at the location is limited by the tightening screw 55.

[0035] In detail, the adjustment plate 53 should be made of a softer, more easily deformed structure, such as a plastic plate, or a thinner stainless steel sheet, and the bottom plate 52 should be made of a harder, less easily deformed structure, such as a thicker stainless steel plate, or a layer of glass plate should be fixed on the inner side of the bottom plate 52.

[0036] In actual use, the flow rate and pressure of the slurry in the middle of the discharge port 51 are often still the largest, that is, the discharge volume is the largest, so the gap of the discharge port 51 in the middle can be adjusted to be smaller and larger on both sides. Of course, the above is the actual application of the applicant, and it is adjusted according to the actual working conditions.

[0037] As an advanced solution for the adjustment mechanism, as shown in the attached Figure 7-8 As shown, the end of the distribution box 2 is fixedly connected to the soft discharge barrel 6, and the two sides of the soft discharge barrel 6 are respectively fixedly connected to the bottom plate 52 and the adjustment plate 53, and the end of the soft discharge barrel 6 between the bottom plate 52 and the adjustment plate 53 forms a discharge port 51; the bottom plate 52 is fixedly connected to the frame 7, and the frame 7 can be directly fixed to the ground through a support frame, or it can be fixed to the body of other machines, for example Figure 1 The frame in which the steel belt is installed, positioning screws 57 are respectively arranged between the two ends of the adjustment plate 53 and the frame 7, the positioning screws 57 are threadedly connected to the frame 7, and locking nuts 56 are arranged on the positioning screws 57, and the positioning screws 57 are locked relative to the frame 7 and the door frame 54 by multiple locking nuts 56, as shown in the figure, there is a locking nut 56 on each side of the door frame 54, and a locking nut 56 is arranged at the connection between the positioning screw 57 and the frame 7; the frame 7 is fixedly connected to the door frame 54, and the two sides of the frame 7 are respectively fixedly connected to the two ends of the door frame 54, and the door frame 54 is spaced apart. Adjustment mechanisms are arranged on the door frame 54, and the adjustment mechanisms are tightening screws 55, and the end of the tightening screws 55 faces the adjustment plate 53, and the tightening screws 55 are provided with locking nuts 56, and the tightening screws 55 are locked relative to the door frame 54 by one or two locking nuts 56.

[0038] The overall spacing between the bottom plate 52 and the adjustment plate 53 is determined by the positioning screw 57 , and the size of the discharge port 51 at the corresponding position is determined by the tightening screw 55 .

[0039] The adjustment structure of the tightening screw 55 cannot make the size of the discharge port 51 arranged in a wave shape. However, in actual use, there are often only 1-2 places where the discharge is uneven, and only these places need to be adjusted.

[0040] Further preferably, since the soft discharge barrel 6 is continuously subjected to the pressure of outward tension, in order to improve the strength, as shown in the attached Fig. 9 As shown, the soft discharge barrel 6 is made of rubber, and a metal wire mesh 8 is coated inside the rubber to prevent damage due to over-expansion.

[0041] In actual use, the thickness can be measured by measuring the thickness through the arrangement method of the CN202311619192X intelligent vermicelli transparency detection system, transparency detection mechanism and detection method proposed by the applicant, and the thickness detection mechanism mentioned in the CN2023116376362 cicada wing rice noodle manufacturing method, mechanism and intelligent vermicelli thickness detection system, to find out whether the slurry quantity is roughly uniform, and adjust the interval size of the discharge port 51 through the tightening screw 55.

[0042] The above is only a preferred embodiment of the present invention. It should be pointed out that for those skilled in the art, several changes and improvements can be made without departing from the overall concept of the present invention, which should also be regarded as the scope of protection of the present invention.
