Description

Technical Field

[0001] The invention relates to the field of pasta drying and processing, in particular to an air energy rice noodle drying machine. Background Art

[0002] In the traditional hanging air-drying system, in the step of drying the pasta, the pasta is hung on a dough pole 3 to 4 meters high, and then a hot air flow is blown from top to bottom on the pasta, and the hot air flow dries the pasta. At the same time, the hot air flow can continuously shake the pasta. The continuous shaking process can prevent the pasta from bending due to uneven dough mixing, and make the pasta more evenly dried by the wind, while increasing the elasticity of the pasta and improving the taste of the pasta. However, in the step of drying the pasta using the existing dryer instead of the traditional hanging air-drying system, the pasta is conveyed to the drying cabin by a conveyor belt for continuous drying. This treatment method can improve the drying efficiency of the pasta and reduce the heat loss caused by the outflow of the hot air. However, this treatment method cannot simulate the shaking of the pasta caused by the traditional hanging air-drying system in the step of drying the pasta, resulting in a large difference in the taste of the pasta dried by the existing dryer and the taste of the pasta dried by the traditional hanging air-drying system.

DETAILED DESCRIPTION

[0018] Embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0019] Embodiment 1: air energy rice noodle drying machine, such as Figure 1-Figure 8 As shown, it includes a drying chamber 1, an internal circulation heating system, a mounting frame 2, an electric control transmission shaft 31, a conveyor belt 32, a carrier plate 33, a first air supply pipe 4, an air injection pipe 5 and a driving system; the drying chamber 1 is connected with an internal circulation heating system for circulating and providing hot air flow; the drying chamber 1 is fixed with a mounting frame 2; a feeding conveyor 21 and a discharging conveyor 22 are sequentially mounted on the mounting frame 2; two electric control transmission shafts 31 are rotatably connected to the mounting frame 2; a plurality of conveyor belts 32 are commonly wound between the two electric control transmission shafts 31; a plurality of carrier plates 33 for supporting pasta are commonly fixed between all the conveyor belts 32, and every two conveyor belts 32 are connected to the two conveyor belts The areas where the carrier plates 33 between 32 are aligned together form a group of independent drying areas running left and right; each carrier plate 33 is configured as an inclined plate structure inclined outwardly toward one side of the rotation direction; two first air pipes 4 are fixedly connected to the mounting frame 2; the two first air pipes 4 are connected to the internal circulation heating system; a number of jet pipes 5 are commonly connected between the two first air pipes 4; each jet pipe 5 is provided with a jet groove 50 structure, and the jet groove 50 structure of the jet pipe 5 faces the upper transmission area of ​​the conveyor belt 32, and when the hot air flow blown out through the jet groove 50 structure of the jet pipe 5 flows through the pasta from bottom to top, the pasta is driven to shake in the up and down directions by the hot air flow.

[0020] like Figure 3As shown, the internal circulation heating system includes a partition 11, an exhaust fan 12, a heat exchange air supply pipe 121, a condensing dryer 13, a blower 14 and a heater 15; the partition 11 is fixedly connected to the drying chamber 1; an exhaust fan 12 is respectively installed on the front and rear sides of the partition 11; the air outlets of the two exhaust fans 12 are respectively connected to a heat exchange air supply pipe 121; two condensing dryers 13 are installed on the partition 11 and are respectively aligned with the air outlets of the two heat exchange air supply pipes 121; a heater 15 is installed on the partition 11; a blower 14 is installed above the heater 15 to blow air toward the heater 15; and the two first air supply pipes 4 are both connected to the air outlet of the heater 15.

[0021] The working principle of the internal circulation heating system of the air energy rice noodle drying machine of the present invention is as follows: the feeding conveyor 21 continuously conveys the noodles to the independent drying areas composed of the conveyor belts 32 and the carrier plates 33, and the electric control transmission shaft 31 drives the conveyor belts 32 and the carrier plates 33 to convey the noodles to the right to the discharging conveyor 22, and then the discharging conveyor 22 conveys the noodles outward. In this process, Figure 4 As shown, the air supply fan 14 continuously delivers air to the heater 15, and the heater 15 continuously heats the air to become hot air. The hot air is delivered to each jet pipe 5 along the first air delivery pipe 4, and then the hot air passes through the jet slots 50 of each jet pipe 5 toward the outwardly inclined carrier plate 33, and sprays from bottom to top toward the pasta in each independent drying area. The hot air transfers heat to the pasta to dry the pasta. At the same time, the hot air carries away the moisture in the pasta to form a warm and humid airflow. The exhaust fan 12 then continuously draws the warm and humid airflow through the heat exchange inner channel of the heat exchange air delivery pipe 121 toward the condensation dryer 13. The condensation drying component of the condensation dryer 13 transfers the moisture in the airflow during contact with the warm and humid airflow. The remaining low-temperature gas is dried and flows to the heater 15 under the suction action of the blower 14. In the process of flowing through the heat exchange outer channel of the heat exchange air duct 121, the dried low-temperature gas will exchange heat with the warm and humid air flow flowing through the inner channel of the heat exchange air duct 121, so that the warm and humid air flow flowing through the inner channel of the heat exchange air duct 121 is initially cooled down, and the low-temperature gas flowing through the outer channel of the heat exchange air duct 121 is initially heated up. Through this heat exchange step, the heat in the air flow is reused, and the hot air flow is circulated to each independent drying area. While improving the drying efficiency of the pasta, the heat loss caused by the outflow of hot air is reduced.

[0022] like Figure 7 and Figure 8As shown, each jet pipe 5 is rotatably connected to a rotating drum 51; a plurality of diagonal grooves 510 structures are provided on the same side of the surface of each rotating drum 51; a plurality of diagonal grooves 510 structures are also provided on the other side of the surface of each rotating drum 51, and the diagonal grooves 510 structures on both sides of the rotating drum 51 are configured to be symmetrical structures; a first spur gear 52 is fixedly connected to the first rotating drum 51 on the left; a motor 53 is installed on the mounting frame 2; a second spur gear 54 is fixedly connected to the output shaft of the motor 53; the second spur gear 54 is meshed with the first spur gear 52; a pulley 55 is fixedly connected to each rotating drum 51; a transmission belt 56 is commonly wound between all the pulleys 55.

[0023] The working principle of the noodle shaking treatment of the air-energy rice noodle dryer of the present invention is as follows: the airflow flowing from bottom to top through the noodle through the jet slot 50 of the jet pipe 5 will drive the noodle to shake in the up and down directions, and at the same time, the motor 53 drives the second spur gear 54 to rotate, and the second spur gear 54 meshes with the first spur gear 52 to drive the rotating drum 51 connected thereto to rotate, and the rotating drum 51 drives the transmission belt 56 through the pulley 55 to drive the remaining rotating drums 51 to rotate synchronously, so that the symmetrical two-side diagonal grooves 510 on the surface of the rotating drum 51 alternately pass through the jet slot 50 of the jet pipe 5, and when the diagonal groove 510 on one side of the rotating drum 51 passes through the jet slot 50 of the jet pipe 5, the steam ejected from the jet slot 50 of the jet pipe 5 Under the guidance of the twill grooves 510 on this side, the hot air flow will blow the pasta in the independent drying area forward. Then, when the twill grooves 510 on the other side rotating on the rotating drum 51 pass through the jet grooves 50 of the jet pipe 5, the hot air flow ejected from the jet grooves 50 of the jet pipe 5 will blow the pasta in the independent drying area backward under the guidance of the twill grooves 510 on the other side. Under the alternating guidance of the twill grooves 510 on both sides of the rotating drum 51, the hot air flow ejected from the jet grooves 50 of the jet pipe 5 will drive the pasta in the independent drying area to shake in the front and back directions, thereby increasing the shaking amplitude and shaking frequency of the pasta in all directions, thereby achieving the effect of improving the taste of the pasta after the drying process is completed.

[0024] Embodiment 2: Based on embodiment 1, Figure 1-Figure 9 As shown, a plurality of scraper blades 61 are fixedly connected to the discharging conveyor 22 of the present embodiment, and all the scraper blades 61 are respectively in close contact with the front and rear surfaces of each conveyor belt 32; each scraper blade 61 is provided with a wedge-shaped guide ramp structure on the side away from the surface of the corresponding conveyor belt 32; a second air pipe 6 is fixedly connected to the discharging conveyor 22; the second air pipe 6 is connected to the air outlet of the heater 15 of the internal circulation heating system; each scraper blade 61 is provided with a cavity structure connected to the second air pipe 6 inside; each scraper blade 61 has two jet holes 610 structures connected to the internal cavity structure on the wedge-shaped guide ramp structure.

[0025] As the airflow blown out from the air jet pipe 5 continuously throws the pasta toward the conveyor belt 32, the airflow continuously blows the water droplets remaining on the surface of the pasta toward the surface of the conveyor belt 32. Although the hot airflow ejected from the air jet pipe 5 can dry the water droplets remaining on the surface of the conveyor belt 32 in time, there is still a phenomenon of water droplets gathering in local areas of the surface of the conveyor belt 32, so that there is a phenomenon that the local area of ​​the pasta is still adhered to the surface of the conveyor belt 32 after drying. At this time, the conveyor belt 32 and the carrier plate 33 drive the pasta to move through the scraper 61, and the scraper 61 scrapes off the pasta adhering to the local area of ​​the surface of the conveyor belt 32. At the same time, part of the hot air flow blown out from the air outlet of the heater 15 will be ejected outward along the second air supply pipe 6 through the air jet hole 610 structure of the scraper 61 to the area where the pasta adheres to the surface of the conveyor belt 32, so as to concentrate on drying the area on the surface of the conveyor belt 32 where the water droplets gather.

[0026] Embodiment 3: Based on embodiment 1, Figure 1-Figure 8 and Fig.10 As shown, the front and rear surfaces of each conveyor belt 32 of the present embodiment are respectively provided with a plurality of oblique grooves 320 which are sunken in the direction of rotation; when the airflow blown out from the air jet pipe 5 throws the pasta toward the conveyor belt 32, the airflow blows the water droplets remaining on the surface of the pasta into the oblique grooves 320 of the conveyor belt 32, and the water droplets then flow downward along the inside of the oblique grooves 320 of the conveyor belt 32, thereby preventing a large number of water droplets from being blown out from the surface of the pasta and gathering on the surface of the conveyor belt 32, which would increase the adhesion of the pasta to the surface of the conveyor belt 32.

Therefore, all equivalent changes made to the contents described in the claims of the present invention should be included in the scope of the claims of the present invention.
