Carbon Fiber Infrared Heating Tubes for Efficient Tea Drying

As tea processing technology increasingly emphasizes environmental friendliness and energy efficiency, traditional methods of tea drying using coal, wood, and other conventional heat sources no longer meet modern requirements.

Carbon fiber infrared heating technology, widely applied in grains, vegetables, tobacco, and other products, has proven effective in tea drying after several years of research and development.

Studies conducted by a university laboratory confirm that carbon fiber infrared heating technology plays a significant role in tea production and quality control. This article primarily explores its application in enzyme deactivation drying processes, equipment energy efficiency, and its impact on tea quality components.

Prior to this, many users employed shortwave infrared heating tubes or ceramic heating plates. These components emit mid to shortwave infrared radiation, which primarily depends on the moisture content of tea leaves and typically penetrates only the surface layer of moist materials.

During radiation heating, the energy reflected and absorbed by tea leaves decreases with reduced moisture content. Comprehensive analysis of various experimental data indicates that far infrared heating tubes are suitable for drying thin materials. Conversely, shortwave infrared heating tubes are required for thicker drying rooms due to their higher temperatures. However, due to the high temperatures of shortwave infrared heating tubes, tea leaves can discolor during drying, making carbon fiber infrared heating tubes preferable for tea drying processes.

Tea leaves undergo physical and chemical changes during withering and drying, closely related to their moisture content and distribution. These processes involve complex heat and mass transfer phenomena. Currently, carbon fiber infrared drying technology is widely used in grains and vegetables, offering superior appearance, rehydration properties, and retention of nutritional components compared to traditional hot air circulation drying.

However, tea processing, particularly withering and drying, differs significantly from grains and vegetables, necessitating specially designed models and specifications for carbon fiber heating tubes used in tea drying machines.

When operating normally, carbon fiber heating tubes reach surface temperatures ranging from 500°C to 600°C, similar to the temperature and color of burning charcoal. This application in withering and drying processes enhances production efficiency and improves tea quality.
