Description

Technical Field

[0001] This application relates to the field of dryer technology, and in particular to a vermicelli forming dryer. Background Technology

[0002] The vermicelli forming and drying machine is an integrated processing equipment specifically designed for the industrial production of vermicelli (a starch product with starch raw materials such as mung bean starch, sweet potato starch, and pea starch as the core, and the finished product is in the form of thin strips). Its core function is to remove excess moisture from the vermicelli blanks after extrusion through a series of coordinated processes such as "transfer-preheating-hot air drying-filtration and purification" (reducing the moisture content to 12%-15% to meet storage and consumption standards), while simultaneously solidifying the vermicelli shape and improving its texture and elasticity. Ultimately, it achieves standardized processing from wet vermicelli blanks to dry finished vermicelli, making it a key piece of equipment in the vermicelli production process that determines product quality, shelf life, and production efficiency.

[0003] Patent document CN214276432U discloses a vermicelli forming and drying machine, including a drying chamber with a drying device inside. The drying chamber has an inlet and an outlet opposite to each other, and a conveying device is installed on the drying chamber from the inlet to the outlet. A feeding basket is placed on the conveying device, and the size of the feeding basket is smaller than both the inlet and outlet. Multiple partitions are provided inside the feeding basket, dividing it into multiple independent feeding chambers. This application has the effect of reducing damage to the vermicelli and ensuring its integrity.

[0004] Patent document CN212987828U discloses a vermicelli drying machine, including a drying chamber with a heating device inside. The drying chamber contains multiple drying partitions, each with evenly distributed ventilation holes on its bottom surface. The drying partitions are slidably installed within the drying chamber via grooves on its inner sidewall. The beneficial effect of this invention is that by setting up drying partitions, the drying time and degree of drying of vermicelli can be controlled in batches, allowing for timely collection of dried vermicelli without affecting the continued drying of other vermicelli, thus improving the overall drying effect.

[0005] However, existing dryers cannot preheat the vermicelli, resulting in poor drying effect. To address this, a vermicelli forming dryer is proposed. Utility Model Content

[0006] In order to improve the problem that existing dryers cannot preheat the vermicelli, resulting in poor drying effect, this application provides a vermicelli forming dryer.

[0007] The vermicelli forming and drying machine provided in this application adopts the following technical solution:

[0008] A vermicelli forming and drying machine includes: a frame; a drying machine body mounted on the top of the frame; and two glass observation windows, both of which are fixedly connected to the front side of the drying machine body.

[0009] The drying device is located on the right side of the dryer body and is used to dry the vermicelli.

[0010] The filter device is located on the left side of the dryer body and is used to filter the hot air.

[0011] The conveying mechanism, located at the bottom of the dryer body, is used for conveying the vermicelli.

[0012] The sprocket and chain drive mechanism is located on the right side of the transmission mechanism and is used to drive the transmission mechanism and the drying device.

[0013] The preheating device, located on the left side of the dryer body, is used to preheat the vermicelli.

[0014] Preferably, the drying device includes a fixed frame, which is fixedly connected to the right side of the dryer body. A dust cover is installed at the center of the fixed frame, and a fan blade is rotatably connected to the center point of the dust cover. Multiple heating wires are fixedly connected to the inner wall of the fixed frame.

[0015] Preferably, the filtration device includes a flow equalization plate, which is fixedly connected to the left side of the fixed frame. A first filter plate is fixedly connected to the left side of the flow equalization plate. When the fan blades rotate, airflow is generated. At the same time, multiple heating wires on the inner wall of the fixed frame are energized and heated. The airflow is heated into hot air as it passes through the heating wires. When the hot air flows to the left, it first passes through the flow equalization plate to make the airflow evenly distributed, and then passes through the first filter plate to filter dust and impurities, forming clean and uniform dry hot air.

[0016] Preferably, the transmission mechanism includes a placement frame and multiple transmission rollers, all of which are rotatably connected inside the frame. Multiple gears are fixedly connected to the right side of each transmission roller, and these gears mesh with each other. A servo motor is mounted on the left side of the frame, and the output shaft of the servo motor is fixedly connected to the left side of the last gear among the multiple gears. The placement frame is located on top of the multiple transmission rollers. When the multiple gears rotate, they drive the fixed transmission rollers on the left side to rotate synchronously, placing the placement frame containing the vermicelli blanks on top of the transmission rollers. The rotation of the transmission rollers causes the placement frame and the internal vermicelli blanks to move at a uniform speed, achieving stable transmission of the vermicelli.

[0017] Preferably, the sprocket and chain drive mechanism includes a chain, a rotating shaft fixedly connected to the right side of the last gear among multiple gears, a sprocket fixedly connected to the right end of the rotating shaft, and another sprocket connected to the sprocket via chain drive. The other sprocket is fixedly connected to the left side of the fan blade. A limit wheel is fixedly connected to the right side of the frame, located on the slack side of the chain. When the servo motor is started, its output shaft drives the last gear among multiple gears to rotate. Because the multiple gears mesh with each other, they drive all gears to rotate synchronously. At the same time, the rotating shaft fixed to the right side of the last gear rotates with it, driving the sprocket at the right end of the rotating shaft to rotate. This sprocket is connected to another sprocket via chain drive, driving the fan blade fixed to the other sprocket to rotate.

[0018] Preferably, the preheating device includes a collector, which is fixedly connected to the left side of the dryer body. A rubber baffle is fixedly connected to the left side of the collector, and a conduit is fixedly connected to the left side of the collector. A preheating frame is fixedly connected to the bottom of the frame, and the conduit is fixedly connected to the preheating frame. A second filter plate is fixedly connected to the inner wall of the left side of the collector. Some of the heat generated during the drying process is collected by the collector, filtered by the inner second filter plate, and then transported to the preheating frame through the conduit to preheat the vermicelli blanks before they enter the dryer. The rubber baffle can reduce heat loss.

[0019] In summary, this application includes at least one of the following beneficial technical effects:

[0020] 1. Some of the heat generated during the drying process is collected by the collector, filtered by the internal second filter plate, and then transported to the preheating frame through the conduit to preheat the vermicelli blanks before they enter the dryer; the rubber baffle can reduce heat loss.

[0021] 2. Airflow is generated by the rotation of the fan blades. At the same time, multiple heating wires on the inner wall of the fixed frame are energized and heated. The airflow is heated into hot air as it passes through the heating wires. When the hot air flows to the left, it first passes through the flow equalization plate to make the airflow evenly distributed, and then passes through the first filter plate to filter dust and impurities, forming clean, uniform, dry hot air.

[0027] Example 1

[0028] The following is in conjunction with the appendix Figures 1-4 The first embodiment of this application will be described in further detail.

[0029] A vermicelli forming and drying machine includes: a frame 1; a drying machine body 5, mounted on the top of the frame 1; and two glass observation windows 4, both of which are fixedly connected to the front side of the drying machine body 5.

[0030] A drying device is located on the right side of the dryer body 5 and is used to dry the vermicelli.

[0031] A filter device is located on the left side of the dryer body 5 and is used to filter hot air.

[0032] The conveying mechanism, located at the bottom of the dryer body 5, is used for conveying the vermicelli.

[0033] The sprocket and chain drive mechanism is located on the right side of the transmission mechanism and is used to drive the transmission mechanism and the drying device.

[0034] The preheating device is located on the left side of the dryer body 5 and is used to preheat the vermicelli.

[0035] Reference Figure 2 The drying device includes a fixed frame 21, which is fixedly connected to the right side of the dryer body 5. A dust cover 6 is installed at the center of the fixed frame 21, and a fan blade 7 is rotatably connected to the center point of the dust cover 6. Multiple heating wires 17 are fixedly connected to the inner wall of the fixed frame 21. The filtration device includes a flow equalization plate 16, which is fixedly connected to the left side of the fixed frame 21. A first filter plate 15 is fixedly connected to the left side of the flow equalization plate 16. The fan blade 7 rotates to generate airflow, and at the same time, the multiple heating wires 17 on the inner wall of the fixed frame 21 are energized and heated. The airflow is heated into hot air as it passes through the heating wires 17. When the hot air flows to the left, it first passes through the flow equalization plate 16 to make the airflow evenly distributed.

[0036] Reference Figure 3The transmission mechanism includes a placement frame 11 and multiple transmission rollers 2. The multiple transmission rollers 2 are rotatably connected inside the frame 1. Multiple gears 13 are fixedly connected to the right side of each of the multiple transmission rollers 2. The multiple gears 13 mesh with each other. A servo motor 18 is installed on the left side of the frame 1. The output shaft of the servo motor 18 is fixedly connected to the left side of the last gear 13 among the multiple gears 13. The placement frame 11 is located on top of the multiple transmission rollers 2. When the multiple gears 13 rotate, they drive the fixed transmission rollers 2 on the left side to rotate synchronously. The placement frame 11 containing the vermicelli blanks is placed on top of the transmission rollers 2. The rotation of the transmission rollers 2 drives the placement frame 11 and the vermicelli blanks inside to move at a uniform speed, so as to achieve stable transmission of vermicelli.

[0037] Reference Figure 4 The preheating device includes a collector 19, which is fixedly connected to the left side of the dryer body 5. A rubber baffle 22 is fixedly connected to the left side of the collector 19, and a conduit 3 is fixedly connected to the left side of the collector 19. A preheating frame 12 is fixedly connected to the bottom of the frame 1. The conduit 3 is fixedly connected to the preheating frame 12. A second filter plate 20 is fixedly connected to the inner wall of the left side of the collector 19. Some of the heat generated during the drying process is collected by the collector 19, filtered by the inner second filter plate 20, and then transported to the preheating frame 12 through the conduit 3 to preheat the vermicelli blanks before they enter the dryer. The rubber baffle 22 can reduce heat loss.

[0038] The implementation principle of the vermicelli forming and drying machine in this application embodiment is as follows: The servo motor 18 is started, and its output shaft drives the last gear 13 among multiple gears 13 to rotate. Because the multiple gears 13 mesh with each other, all gears 13 are driven to rotate synchronously. Simultaneously, the rotating shaft 14 fixed to the right side of the last gear 13 rotates with it, driving the sprocket 8 at the right end of the rotating shaft 14 to rotate. This sprocket 8 is connected to another sprocket 8 via a chain 9 and a limiting wheel 10, driving the fan blade 7 fixed to the other sprocket 8 to rotate. The rotation of the fan blade 7 generates airflow, and simultaneously, multiple heating wires 17 on the inner wall of the fixed frame 21 are energized and heated. The airflow is heated into hot air by the heating wires 17. When the air flows to the left, it first passes through the flow equalization plate 16 to distribute the airflow evenly. When the multiple gears 13 rotate, they drive the fixed transmission rollers 2 on the left to rotate synchronously. The placement frame 11 containing the vermicelli blanks is placed on top of the transmission rollers 2. The rotation of the transmission rollers 2 drives the placement frame 11 and the vermicelli blanks inside to move at a uniform speed, achieving stable transmission of the vermicelli. At the same time, some of the heat generated during the drying process is collected by the collector 19, filtered by the internal second filter plate 20, and then transported to the preheating frame 12 through the conduit 3 to preheat the vermicelli blanks before they enter the dryer. The rubber baffle 22 can reduce heat loss and preheat in advance, which can prevent the breakage of the vermicelli due to temperature difference.

[0039] Example 2

[0040] The difference between this embodiment and Embodiment 1 is that a vacuum cleaner is installed on the left side of the collector 19, and the vacuum cleaner cleans the debris inside the chamber of the collector 19.

[0041] Example 3

[0042] The difference between this embodiment and Embodiment 1 is that gear 13 is replaced with a synchronous gear, multiple synchronous gears are connected by the same synchronous toothed belt, and the output shaft of servo motor 18 is fixedly connected to the left side of the last synchronous gear among the multiple synchronous gears.

[0043] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
