Description

Technical Field

[0001] This invention relates to the field of vermicelli production equipment technology, and in particular to a multifunctional vermicelli production line. Background Technology

[0002] A vermicelli production line can increase the output of ready-to-eat vermicelli. A vermicelli production line consists of multiple equipment stages. For example, a multi-functional, high-capacity, automatic vermicelli production line with Chinese patent publication number CN109259285A includes, according to the material conveying direction, a continuous conveyor weighing scale, a continuous powder-liquid mixer, a dough maturation conveyor, a delayed conveyor, a cooking and grinding machine, a dough quantitative supply machine, a combined maturation and extrusion device, a vermicelli cooking machine, a cooling machine, a quantitative cutting machine, a dryer, an air cooler, a transverse conveyor, and a packaging conveyor. The continuous conveyor weighing scale conveys dry powder to the continuous powder-liquid mixer, where it is mixed with liquid supplied by a quantitative supply tank. The continuous powder-liquid mixer conveys the dough to the delayed conveyor via the dough maturation conveyor. The delayed conveyor, cooking and grinding machine, dough quantitative supply machine, combined maturation and extrusion device, vermicelli cooking machine, cooling machine, quantitative cutting machine, dryer, air cooler, transverse conveyor, and packaging conveyor are sequentially connected. Existing vermicelli production lines use water and dry powder to directly mix and then perform the mixing operation. Vermicelli made primarily from dry powders such as mung beans, corn, and sweet potatoes is easy to mix evenly in a mixer because it has low dietary fiber content. Therefore, using the above-mentioned mixer and extruder together can produce good vermicelli. However, for dry powders with high dietary fiber content and a variety of raw materials, the mixing process is not uniform, resulting in the inability to form vermicelli in the extruder. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a multifunctional vermicelli production line that can adapt to the production of vermicelli from dry powder with different fiber types.

[0004] To solve the above-mentioned technical problems, the technical solution of the present invention is: a multi-functional vermicelli production line, which, in sequence according to the material conveying direction, includes a dry powder quantitative conveying device, a powder liquid quantitative dispensing device, a powder mixing device, a raw vermicelli dough conveyor, a drum powder conveyor, a vermicelli dough cooking machine, a cooked vermicelli dough conveyor, a vermicelli dough extruder, a vermicelli conveyor, a vermicelli pelletizer, a high-pressure extrusion machine, a vermicelli stabilizer, an anhydrous ambient temperature loosening machine, a vermicelli cooking machine, a moisturizing jelly machine, a vermicelli stretching machine, a cutting and boxing machine, a vermicelli block shaping machine, a dryer, an air cooler, and packaging equipment;

[0006] The principle of this invention: In the production line of this invention, a pulping machine and a slurry coating machine are added. The pulping machine mixes part of the dry powder with water to form a slurry. The slurry replaces the water in the mixing of the powder. The slurry is then evenly mixed with the dry powder of mixed grains with more dietary fiber in the mixing machine through the slurry coating machine to form a dough.

[0015] The beneficial effects of this invention compared to the prior art are:

[0016] 1. The production line of this invention adds a pulping machine and a slurry coating machine. The pulping machine mixes some of the sticky dry powder with water to form a slurry. The slurry replaces water in the mixing process. The slurry is then mixed evenly with the fibrous dry grain powder in the mixing machine by the slurry coating machine to form a dough. During the slurry coating process and the mixing process in the mixing machine, the participation of the slurry in the mixing process makes the powder and slurry more evenly mixed. After the sticky dry powder and the fibrous dry powder are evenly mixed, they are heated to form a uniform gelatinized state.

[0017] 2. The waterless room temperature shredding process has good continuity and high processing efficiency. The waterless room temperature shredding machine is low in cost, environmentally friendly and saves water resources. It avoids water interference with the vermicelli, making it clean and hygienic. The shredding process at room temperature avoids the energy consumption caused by the freezing process.

[0018] 3. Since the vermicelli is not granulated at the outlet after extrusion, but is cooled and its viscosity reduced by the vermicelli conveyor before granulation, the adhesion of the powder is reduced during granulation, resulting in a more ideal granulation effect.

[0019] 4. After the vermicelli is cut into granules by the pelletizer, it enters the high-pressure extruder, which makes the granules uniform again during extrusion and makes it easier to remove the air carried in the feed. This makes the vermicelli extrusion smooth, stable and fast, which can increase the output of the vermicelli production line. Attached Figure Description

[0032] like Figure 1As shown, a multi-functional vermicelli production line, arranged sequentially according to the material conveying direction, includes: a dry powder quantitative conveying device, a powder-liquid quantitative dispensing device, a powder mixing device 4, a raw starch dough conveyor 5, a drum powder conveyor 6, a starch dough steaming machine 7, a cooked starch dough conveyor 8, a starch dough extruder 9, a vermicelli conveyor 10, a vermicelli pelletizer 11, a high-pressure extrusion machine 13, a vermicelli stabilizer 14, an anhydrous ambient temperature loosening machine 15, a vermicelli steaming machine 16, a cooling machine 17, a vermicelli stretching machine 18, a cutting and boxing machine 19, a starch block shaping machine 20, a dryer 21, an air cooler 22, and packaging equipment. This production line can produce potato, bean, and grain vermicelli. Even using potato flour, which is high in dietary fiber, as the main raw material, and mixing it with other dry powders such as beans and grains, it can produce instant potato vermicelli. In principle, it can use one or more high-fiber dry powders as raw materials, and mix them with other viscous dry powders to produce different types of instant vermicelli.

[0033] The powder-liquid quantitative distribution equipment includes a quantitative powder feeding device and a quantitative water supply machine. The quantitative powder feeding device is used to store and quantitatively convey dry powder, and the quantitative water supply machine is used to quantitatively supply water. The quantitative powder feeding device includes, in sequence according to the material conveying direction, a dry powder filter 1, a powder mixing mechanism 2 connected in series at one or more stages, and a quantitative powder storage tank 3. In this embodiment, a two-stage powder mixing mechanism 2 is used with directional mixing and conveying. The powder mixing mechanism 2 includes, in sequence according to the material conveying direction, a raw material powder storage tank, a continuous quantitative powder mixing machine, a continuous mixer, and a dry powder pneumatic conveyor. The output end of the dry powder filter is connected to the airlock at the input end of the dry powder pneumatic conveyor of the first-stage powder mixing mechanism. The output end of the dry powder pneumatic conveyor of the first-stage powder mixing mechanism is connected to the input end of the raw material powder storage tank.

The output end of the dry powder pneumatic conveyor of the final-stage powder mixing mechanism is connected to the input end of the quantitative powder storage tank.

[0034] like Figures 2 to 5As shown, the powder mixing equipment 4 includes a pulping machine 41, a slurry coating machine 42, and a powder mixing machine 43. A quantitative powder dispensing device delivers dry powder to a quantitative storage tank 3 and quantitatively supplies water to the pulping machine 41. The quantitative storage tank 3 quantitatively delivers dry powder to the powder mixing machine 43. The pulping machine 41 mixes a portion of the dry powder and water into a slurry and then delivers the slurry to the slurry coating machine 42. The slurry coating machine 42 coats the dry powder in the powder mixing machine 43, where the slurry and dry powder form a raw powder agglomerate. The pulping machine 41 includes a tank body 411, a cover that mates with the tank body, a stirring motor 412 mounted on the cover, a coupling 413 connected to the output shaft of the stirring motor, a stirring shaft 415 connected to the coupling 413, and stirring blades 414 mounted on the stirring shaft 415.

The slurry coating disc 423 is located above the powder mixer 43 and is the same size as the opening of its powder mixing bucket. One side of the slurry coating disc 423 is hinged to the sides of both ends of the powder mixing bucket opening of the powder mixer 43. The slurry coating disc 423 includes a frame and a filter screen located on the frame. The slurry coating tank 422 is elongated, and its length is the same as that of the slurry coating tank. The length of the plate 423 is approximately equal to that of the slurry trough 422, which is located above the slurry plate 423 in the middle position. The middle section of the slurry trough 422 is a circular tube, and the two end sections are semi-circular grooves. After the slurry in the slurry trough 422 is filled, it overflows through the side holes and both sides onto the slurry plate 423 below. After the slurry is evenly dispersed by the filter screen of the slurry plate 423, it is poured into the powder mixer 43. The middle section of the slurry trough 422 is a circular tube, and the output end of the slurry guide pipe 421 is flexibly inserted into the middle section of the circular tube. The slurry plate 423 is provided with a bracket, which supports the slurry trough 422.

[0035] The raw starch dough conveyor is a trough-type starch dough conveyor, which includes a frame, a starch dough trough, a conveyor belt and a starch dough dispersing mechanism, and has the functions of temporary storage and conveying of starch dough.

[0036] The powder conveyor includes a conveyor frame, a conveyor chain, several baskets mounted on the conveyor chain, powder containers inside the baskets, an automatic powder container unloading mechanism, and a drive mechanism for driving the conveyor chain. The output end of the raw powder dough conveyor is equipped with a powder dough quantitative weighing device. Powder dough weighed by the device enters the powder conveyor, with the aim of ensuring that the dough reaches the powder dough cooking machine after one hour of aging.

[0037] The dough powder cooking machine includes a frame, a double-layer grinding drum, a stirring mechanism, a transmission mechanism, a steam filter, a safety pressure reducing valve, a steam injection pipe, and a pneumatic switch mechanism for the upper and lower drum lids. The drum powder conveyor passes through the dough powder cooking machine to cook the dough powder. Each drum cooking cycle is 15 minutes, with a processing capacity of 50kg to 70kg of dry powder per drum.

[0038] The cooked dough conveyor includes a frame, a dough trough, a conveyor belt, a dough breaker, a transmission mechanism, and a sliding water receiving trough. The cooked dough conveyor carries the temporary storage of cooked dough unloaded from four dough cooking machines and continuously feeds it to the dough extruder. After being loosened by the breaker, the cooked dough falls into the hopper of the noodle extruder.

[0039] like Figure 6 , 7 As shown, the dough extruder 9 includes one or more extrusion units arranged side by side. In this embodiment, two extrusion units are provided to increase output. Each extrusion unit includes an extrusion barrel 94, an extrusion screw 95 disposed within the extrusion barrel 94, an extrusion drive mechanism 99 for driving the extrusion screw 95 to rotate, a hopper 92 located at the input end of the extrusion barrel 94, and an extrusion die 96 located at the output end of the extrusion barrel 94. The extrusion die 96 is connected to the input end of the noodle conveyor 10. A support seat 962 supporting the end of the extrusion screw 95 is provided at the middle of the front end of the extrusion die 96. The rear end of the extrusion die 96 is connected to an extrusion template 961, and an extrusion hole 963 is provided on the extrusion template 961. An outer jacket is provided outside the extrusion barrel 94, with an inlet and an outlet. A temperature measuring instrument is provided at the outlet. By injecting cooling water into the extrusion barrel 94, the temperature of the dough is controlled, thereby controlling the quality of the extruded noodles to meet the processing requirements of subsequent equipment. The extrusion drive mechanism 91 includes a motor, a reducer, and a drive shaft. The motor drives the reducer via a belt, and the output shaft of the reducer drives the drive shaft via a coupling. The drive shaft drives the extrusion screw 95 via gear meshing. One drive shaft can drive two extrusion screws 95 simultaneously. The discharge hopper 92 is equipped with a loosening shaft 93, the power of which can come from the extrusion drive mechanism 91. When the powder agglomerates enter the extrusion barrel 94, they are evenly dispersed by the loosening shaft.

[0040] like Figure 6 , 8 As shown, the input end of the vermicelli conveyor 10 is lower and connects to the vermicelli extruder 9, while the output end of the vermicelli conveyor 10 is higher and connects to the vermicelli pelletizer 11. One end of the vermicelli conveyor 10 is equipped with a support caster 101, and the other end is equipped with a support rotating seat 102. The support rotating seat 102 includes a support part 1021 and a rotating part 1022 located on the upper end of the support part 1021. Depending on the layout requirements of the site, the vermicelli conveyor 10 can rotate at a certain angle to connect with the preceding and following equipment.

[0041] like Figure 6 , 9As shown, the vermicelli pelletizer 11 is located at the output end of the vermicelli conveyor 10. The vermicelli pelletizer 11 includes an anvil roller 111, a cutter roller 112, cutters, and a pelletizing drive mechanism that drives the anvil roller and cutter roller to rotate. The size of the pellets is adjusted by adjusting the rotation speed of the cutter roller. The cutter roller 112 of the vermicelli pelletizer 11 is equipped with two symmetrical rotating pelletizing cutters 1121. The vermicelli dough is extruded into long strips by the vermicelli extruder 9. The vermicelli is conveyed and cooled by the vermicelli conveyor 10. After cooling, the vermicelli is cut into pellets by the vermicelli pelletizer 11. Since the vermicelli dough is not cut into pellets at the outlet after extrusion, but is cooled to reduce viscosity before pelletizing, the adhesion of the powder is reduced during pelletizing, resulting in a more ideal pelletizing effect.

[0042] The high-pressure extruder 13 includes a frame, a feeding trough, a twin-screw extruder, a stainless steel extrusion head, and a feeding mechanism. In this embodiment, two high-pressure extruders 13 are used. The dough undergoes multi-stage maturation, extrusion, and turning to ensure the uniform blending of various components of potatoes, beans, and grains. Then, through the powerful extrusion of the high-pressure extruder 13, it produces conical fibers with a smooth surface, high fiber density, and good elasticity. Figure 9 As shown, the output end of the high-pressure extruder 13 passes through the stacking conveyor 12 and the elevator 27 in sequence before connecting to the input end of the vermicelli stabilizer 14. The elevator 27 is equipped with a cooling fan assembly 28. The stacking conveyor 12 adjusts the arrangement of the vermicelli after it comes out of the high-pressure extruder 13 onto the conveyor belt, which is beneficial for the subsequent loosening of the vermicelli. The vermicelli stabilizer 14 includes several layers of constant-speed conveyor belts connected end to end. In this embodiment, 8-10 layers of constant-speed conveyor belts can be set. The vermicelli can fall from the end of the upper constant-speed conveyor belt to the beginning of the lower constant-speed conveyor belt. The vermicelli is conveyed in the vermicelli stabilizer 14 for about 1 hour. During the conveying process, the vermicelli cools down and becomes more stable. After about 1 hour of aging treatment in a set temperature and humidity environment, the vermicelli is stabilized to a state where it can be loosened.

[0043] like Figure 10 , 11As shown, the anhydrous ambient temperature loosening machine 15 includes, in sequence according to the material conveying direction, a front pressure loosening machine 151, a back pressure loosening machine 152, and a differential speed loosening machine 153. The differential speed loosening machine 153 is located above the vermicelli cooking machine 16. The front pressure loosening machine 151 and the back pressure loosening machine 152 are arranged opposite each other and located above the differential speed loosening machine 153. The vermicelli stabilizer 14 is located above the front pressure loosening machine 151 and the back pressure loosening machine 152. The front pressure loosening machine 151 includes several sets of first pressure roller groups 1511 and a first conveying nylon belt 1512 passing through the first pressure roller groups 1511. In this embodiment, a total of six sets of first pressure roller groups 1511 are provided. Each first pressure roller group 1511 includes a first upper pressure roller and a first lower support roller. The vermicelli enters the six sets of first pressure roller groups sequentially via the first conveyor belt. The multiple sets of first pressure roller groups perform "self-weight" adjustable compression on the stabilized front side of the vermicelli, causing the overlapping filaments to shift multiple times. The reverse pressure loosening machine 152 includes several sets of second pressure roller groups and a second conveying nylon belt passing through the second pressure roller groups. In this embodiment, a total of six sets of second pressure roller groups are provided. Each second pressure roller group includes a second upper pressure roller and a second lower support roller. The vermicelli enters the six sets of second pressure roller groups sequentially via the second conveyor belt. The multiple sets of second pressure roller groups perform "self-weight" adjustable compression on the stabilized reverse side of the vermicelli, causing the overlapping filaments to shift multiple times. The front pressure loosening machine 151 and the back pressure loosening machine 152 are at the same height and opposite each other, connected by a constant speed conveyor belt. The differential speed loosening machine 153 includes a differential speed conveyor belt 1531, which includes several conveyor belt units with different speeds. The vermicelli is stretched by conveying at different speeds, further loosening the vermicelli and making it completely loose. The stretched straight strands are "folded" on the steaming mesh belt 161 of the vermicelli steaming machine 16 and then steamed. At this time, the steamed vermicelli is truly "locked in surface steaming", which adds a gelatinized layer to the surface of the vermicelli, making it less likely to become mushy or break when eaten. After steaming, the vermicelli enters the moisturizing jelly machine 17. After moisturizing and jelly drying for more than 10 minutes, it passes through the vermicelli stretching machine 18 again, which stretches the "folded vermicelli" before steaming into straight strands, loosening the strands again. Finally, it is conveyed into the cutting and boxing machine 19 for quantitative cutting and boxing. The waterless room temperature shredding process has good continuity and high processing efficiency. The waterless room temperature shredding machine is low in cost, environmentally friendly and saves water resources. It avoids water interference with the vermicelli, making it clean and hygienic. The shredding process at room temperature avoids the energy consumption caused by the freezing process.

[0044] like Figure 1As shown, the packaging equipment includes, in sequence according to the material conveying direction, a diversion conveyor 23, a packaging conveyor 24, a packaging machine 25, and a finished product conveyor 26. The powder block shaping machine positions and shapes the surface of the freshly entered vermicelli blocks, ensuring uniform thickness and an attractive appearance after drying, which facilitates packaging. The dryer is divided into front and rear sections, with automatic constant temperature and humidity, and evenly circulating hot air to penetrate the powder blocks. The air cooler fully cools the powder blocks before they leave the box, reducing powder breakage. The diversion conveyor automatically guides and positions the powder blocks during transport, facilitating rapid and automatic switching to continuous conveying and packaging when the packaging machine needs to be stopped to change the packaging film.
