Description

Technical Field

[0001] This utility model relates to the field of gluten-free rice flour processing technology, and in particular to a low-temperature drying device for gluten-free rice flour. Background Technology

[0002] Gluten-free rice noodles are a type of food made primarily from rice through refined processing. The production process typically involves low-temperature drying to effectively remove moisture without damaging the nutritional components and texture, thus extending the product's shelf life. Undried gluten-free rice noodles are injected into a drying device, where heating elements supply hot air while a vibrator simultaneously vibrates the device, ensuring thorough contact between the noodles and the hot air. Excess hot air is then expelled through an exhaust pipe. However, if the temperature of the hot air inside the drying device is too high, a single exhaust pipe cannot achieve rapid removal, and excessively high temperatures can negatively impact the quality, nutritional value, and safety of the rice noodles.

[0003] To address the above issues, a low-temperature drying device for gluten-free rice flour has been developed. Utility Model Content

[0004] To overcome the shortcomings of the fact that when the temperature of the hot air inside the drying device is too high, a single exhaust pipe cannot achieve the effect of rapid discharge, and that excessively high temperature will affect the quality, nutritional value and safety of rice noodles, this utility model provides a low-temperature drying device for gluten-free rice noodles.

[0005] The technical solution of this utility model is: a low-temperature drying device for gluten-free rice flour, including a lower base, a top cover installed on the lower base, vibrators installed on both the front and rear sides of the lower base, three display screens installed on both the front and rear sides of the top cover, a feeding hopper connected to the upper left side of the top cover, a discharging hopper connected to the lower right side of the lower base, a heating component installed on the front side of the lower base, a first exhaust pipe connected to the upper side of the top cover, an emergency exhaust mechanism provided on the top cover, the emergency exhaust mechanism including a hydraulic cylinder, the hydraulic cylinders installed on both the front and rear sides inside the top cover, connecting rods rotatably connected to the telescopic ends of the hydraulic cylinders, a cover plate rotatably connected between the connecting rods, the cover plate rotatably connected to the top cover, a sealing ring connected to the cover plate, and a second exhaust pipe connected to the upper right side of the top cover.

[0006] Furthermore, it also includes a cooling mechanism, which includes an exhaust fan. The exhaust fan is placed on the front right side of the lower base, and an air inlet pipe is connected to the left side of the exhaust fan. An air supply pipe is connected between the exhaust fan and the lower base.

[0007] Furthermore, the lower base is provided with a support seat that provides shock absorption.

[0008] Furthermore, the top cover has a detachable connection structure.

[0009] Furthermore, the feed hopper has an inverted trapezoidal structure.

[0010] Furthermore, an air inlet pipe is connected between the heating component and the lower base, and the air inlet pipe is a stretchable corrugated pipe.

[0011] By adopting the above technical solutions, the beneficial effects of this utility model are as follows:

[0012] 1. This utility model is equipped with an emergency exhaust mechanism. The hydraulic cylinder drives the connecting rod to rotate, which in turn drives the right side of the cover plate to move downward, so that the cover plate and the top cover are no longer in a sealed state. Hot air will be discharged outward through the second exhaust pipe due to the influence of air pressure, thereby ensuring the air temperature balance between the lower base and the top cover, which is conducive to the safe and smooth operation of rice noodle drying.

[0013] 2. This utility model is equipped with a cooling mechanism that uses an exhaust fan to draw in cold air and delivers the cold air to the space enclosed by the lower base and the top cover through an air supply pipe, thereby quickly reducing the temperature of the space and adjusting it to a suitable temperature to meet the drying requirements of rice noodles.

Detailed Implementation

[0019] The preferred technical solution of this utility model will be described in detail below with reference to the accompanying drawings.

[0020] Example 1

[0021] A gluten-free rice flour low-temperature drying device, such as Figures 1-3 As shown, the device includes a lower base 1, with a shock-absorbing support at the bottom. A top cover 2 is mounted on the lower base 1, and the top cover 2 has a detachable connection structure. Vibrators 3 are mounted on both the front and rear sides of the lower base 1. Three display screens 4 are mounted on both the front and rear sides of the top cover 2. A feed hopper 5 with a trapezoidal structure is connected to the upper left side of the top cover 2. A discharge hopper 6 is connected to the lower right side of the lower base 1. A heating element 7 is mounted on the front of the lower base 1, and an air inlet is connected between the heating element 7 and the lower base 1. The intake pipe is a stretchable corrugated pipe. The top cover 2 is connected to the first exhaust pipe 8. An emergency exhaust mechanism 9 is installed on the top cover 2. The emergency exhaust mechanism 9 includes a hydraulic cylinder 91. Hydraulic cylinders 91 are installed in both the front and rear parts of the top cover 2. The extension and retraction ends of the hydraulic cylinders 91 are rotatably connected to the connecting rods 92. A cover plate 93 is rotatably connected between the connecting rods 92. The cover plate 93 is rotatably connected to the top cover 2. A sealing ring 94 is connected to the cover plate 93. The upper right side of the top cover 2 is connected to the second exhaust pipe 95.

[0022] It should be noted that gluten-free rice cereal is a food product made primarily from rice through refined processing. The production process typically involves low-temperature drying to effectively remove moisture without damaging the nutritional components and texture, thus extending the product's shelf life. First, the undried gluten-free rice cereal is injected into the lower base 1 through the feed hopper 5. The heating element 7 delivers hot air between the lower base 1 and the top cover 2 through the air inlet pipe. The hot air heats the air and circulates it, transferring heat to the gluten-free rice cereal and causing moisture evaporation. Simultaneously, the vibrator 3 vibrates the lower base 1, achieving a vibration effect on the rice cereal, thus allowing the rice cereal to interact with the hot air. Sufficient contact ensures more thorough drying of the rice noodles. Excess hot air is discharged through the first exhaust pipe 8. When the temperature of the hot air in the space between the lower base 1 and the top cover 2 becomes too high, emergency venting is required to prevent the high temperature from affecting the quality, nutritional value, and safety of the rice noodles. This can be achieved by activating the hydraulic cylinder 91. The extension end of the hydraulic cylinder 91 drives the connecting rod 92 to rotate, which in turn moves the right side of the cover plate 93 downward, so that the cover plate 93 and the top cover 2 are no longer sealed. The hot air will be discharged through the second exhaust pipe 95 due to the air pressure, thus ensuring the temperature balance of the air enclosed by the lower base 1 and the top cover 2, which is conducive to the smooth and safe operation of the rice noodle drying process.

[0023] Example 2

[0024] Based on Example 1, such as Figure 1 and Figure 4 As shown, it also includes a cooling mechanism 10, which includes an exhaust fan 101. The exhaust fan 101 is placed on the front right side of the lower base 1. An air inlet pipe 102 is connected to the left side of the exhaust fan 101. An air supply pipe 103 is connected between the exhaust fan 101 and the lower base 1.

[0025] It should be noted that when the temperature is too high, the hot air can be discharged outward using the emergency exhaust mechanism 9, or it can be achieved through the cooling mechanism 10, which uses the exhaust fan 101 to draw in cold air and delivers the cold air to the space enclosed by the lower base 1 and the top cover 2 through the air supply pipe 103, thereby quickly reducing the temperature of the space and adjusting it to a suitable temperature to meet the drying requirements of rice noodles.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that variations may be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
