Description

Technical Field

[0001] This utility model belongs to the field of tobacco processing technology, specifically relating to a constant temperature and humidity control system for wind-separated tobacco materials. Background Technology

[0002] Tobacco air separators are used in tobacco processing to remove impurities, classify materials by weight, and optimize material quality. The tobacco air separation process primarily utilizes airflow to separate tobacco materials according to density, weight, or shape, thereby improving tobacco purity and processing efficiency. Because traditional tobacco air separators are connected to the external environment through a hopper, fluctuations in ambient temperature and humidity can cause changes in the moisture content of the tobacco materials, affecting the separation effect and even leading to unstable material quality. For example, excessively high humidity may cause the tobacco materials to absorb moisture and become sticky, while excessively low humidity or high temperature may cause the tobacco materials to lose moisture and break down.

[0003] Current technologies often employ ambient air conditioning and humidification equipment to regulate the temperature and humidity of the air classifier workshop. However, ambient air conditioning cannot directly affect the inside of the air classifier, resulting in uneven temperature and humidity control. This makes it difficult to match the processing requirements of different batches of tobacco, and this solution significantly increases unnecessary energy consumption and wastes data.

[0004] To address the aforementioned problems, this utility model is proposed. Utility Model Content

[0005] To address the shortcomings of existing technologies, the purpose of this invention is to provide a constant temperature and humidity control system for tobacco materials in air separation. This system can precisely control the temperature and humidity of tobacco materials within the air separator without adjusting or modifying existing equipment, providing a constant temperature and humidity environment and significantly improving air separation efficiency. Compared to traditional solutions, this invention also substantially reduces energy consumption.

The constant temperature and humidity control system includes an air conditioning unit 2, a sealing cover 3, and an air supply pipe 4.

[0008] The sealing cover 3 is disposed on the outer periphery of the hopper 11 and forms a sealed space as a whole;

[0009] The air supply pipe 4 is connected to the air conditioning unit 1 and the sealing cover 3 at both ends, and is used to deliver the constant temperature and humidity airflow output by the air conditioning unit 1 to the sealing cover 3.
