Description

Technical Field

[0001] The invention relates to the technical field of tobacco leaf baking and tobacco leaf storage, and specifically provides a mobile high-pressure micro-mist dehumidification machine used for tobacco leaf storage. Background Art

[0002] The mobile high-pressure micro-mist moisture recovery machine is a tobacco leaf moisture recovery equipment. This equipment is used in the tobacco leaf moisture recovery process stage of the intensive flue-curing room tobacco leaf baking process. After the tobacco leaves are baked in the intensive flue-curing room, the tobacco leaves reach the state of yellow leaves and yellow tendons. At this time, the leaves have just completed the continuous baking process under the high-temperature circulating wind environment, and the moisture content is low, about 3-5%. The leaves are dry as a whole. The tobacco leaves are fragile and the main veins are easy to break. It is not suitable to be baked immediately. If the tobacco leaves are moved at this time, it will cause the tobacco leaves to break, which will affect the appearance of the tobacco leaves and even make the tobacco leaves lose their use value, causing great economic losses to tobacco farmers. Therefore, it is necessary to perform appropriate moisture recovery after baking. However, the moisture recovery treatment needs to be strictly controlled: insufficient moisture recovery will make the tobacco leaves fragile, and excessive moisture recovery will make the tobacco leaves too high in moisture content, resulting in heat and mildew during storage, affecting the quality of the tobacco leaves.

[0003] The operation of controlling the moisture regeneration of tobacco leaves can make the tobacco leaves absorb moisture and regenerate moisture to an appropriate degree. Its working mechanism is to use a tobacco leaf rehumidification machine to evenly spray normal temperature water vapor into the air to increase the humidity of the environment around the tobacco leaves.

[0004] Moisture reconditioning machines are also used to preserve tobacco leaves in the grading and storage areas of tobacco leaf purchasing stations. During the placement and storage of tobacco leaves in the tobacco station, the natural evaporation of the water in the tobacco leaves will cause the tobacco leaves to become brittle and break easily, and also lose weight, causing the tobacco station to lose inventory. Therefore, a moisture reconditioning machine is also needed to keep the tobacco leaves at an appropriate moisture content.

[0005] Common rehumidification machines use ultrasonic waves to generate water vapor. This method of generating water vapor is simple and convenient, but the fog particles are large (generally around 1 to 10 um) and the diffusion effect is not good enough. Water droplets easily solidify and fall near the nozzle to form water accumulation, causing uneven rehumidification of tobacco leaves. Some areas have insufficient rehumidification, while others have excessive rehumidification, and may even cause the tobacco leaves to mold and rot. Summary of the invention
