TECHNICAL FIELD

[0002] The exhaust structure of microwave drying machine is an important part of the equipment for removing steam and smoke generated during the heating process, and its design is crucial to ensure the drying effect and the normal operation of the equipment. During the microwave drying process, the moisture in the material is rapidly vaporized to form steam, which diffuses to the surface of the material and is carried to the exhaust port by the airflow in the drying chamber. After the high-power centrifugal fan is started, it generates a strong suction force to extract the moisture and hot air from the exhaust port and discharge them outside the equipment through the exhaust pipe and filter. The entire exhaust system works continuously to ensure that the environment inside the drying chamber remains in a suitable state.

[0003] The patent document with application number 202321767798.3 discloses a drying machine air guide structure, which includes an air guide pipe with an exhaust end at the end. The bottom of the exhaust end is a main air outlet, and the lower part of the exhaust end is provided with side air holes distributed on the peripheral wall. An air guide cover is also provided on the air guide pipe above the exhaust end, and the outer wall of the air guide pipe covered by the air guide cover is provided with upper air holes. This drying machine air guide structure can effectively improve the heating efficiency and has a simple structure, which is very efficient.
