Description

Technical Field

[0001] The utility model relates to the technical field of rice noodle drying, and more specifically, to a high-efficiency rice noodle drying device. Background Art

[0002] Drying equipment refers to a combination of a series of mechanical equipment that uses certain technical means to dry the moisture or other liquids on the surface of an object. The popular drying technologies are mainly ultraviolet drying, infrared drying, electromagnetic drying and hot air drying. They each have their own characteristics and are widely used in the drying of various mechanical equipment and foods. Among them, rice noodles need to be dried using a drying device after production.

[0003] The Chinese patent with the authorization announcement number CN218065794U discloses a drying device for producing rice noodles. The drying box is provided. A support plate is fixedly connected to the bottom of one side of the outer wall of the drying box. A hot air blower is fixedly connected to the top of the support plate. An air outlet is fixedly connected to the output end of the hot air blower. The air outlet runs through the center of the inner wall of the drying box. An air outlet is provided at the part of the air outlet located at the inner wall of the drying box. When the hot air output from the air outlet is blown upward to dry the rice noodles, the air flow blows upward, passes through a plurality of heat absorbing sheets, absorbs a certain amount of waste heat, and then transmits it to a plurality of heat sinks through the heat conducting pipe. The heat is released to the entrance of the rice noodles to achieve preheating of the rice noodles. At the same time, the airflow passes through the deflector cover, which can guide the airflow to the entrance so that the incoming rice noodles are blown by the wind first, increasing the evaporation amount, thereby improving the preheating and drying effect, thereby reducing the power of the hot air blower, improving the waste heat utilization rate, and improving the drying effect. The drying device cannot remove water molecules in the airflow when recovering heat. When the heat is released to the entrance of the rice noodles, the moisture in the gas will gather on the heat absorbing plate and the heat sink, condense into water droplets and finally drip on the rice noodles, resulting in uneven drying of the rice noodles and affecting the quality of the rice noodles drying.
