Description

Technical Field

[0001] This utility model relates to the technical field of tea processing equipment, and in particular to a debris screening device for tea processing. Background Technology

[0002] Tea processing debris screening devices are core equipment in the tea refining process. They are mainly used to separate tea dust, tea ash, and small impurities from qualified tea leaves, improving the integrity, cleanliness, and quality consistency of the finished tea. The screening parameters can be flexibly adjusted according to the processing needs of different tea types such as green tea, black tea, and oolong tea. This reduces the loss of effective components in tea, lowers the labor intensity of manual screening, and improves screening efficiency. It is a key piece of equipment to ensure the commercial value and drinking experience of tea. Tea processing debris screening devices separate tea leaves from debris and impurities based on their differences in characteristics. During operation, a vibrating motor typically drives the screen body to vibrate at high frequency, while a fan generates a stable airflow. After the tea raw materials to be screened are conveyed to the screen surface, qualified tea leaves, due to their larger size and moderate weight, will move along the screen surface to the discharge port under the action of vibration. Smaller, lighter tea dust, tea ash, and fine impurities will either pass through the screen with the corresponding aperture and fall into the lower collection chamber, or be adsorbed and carried away by the airflow, further completing the fine separation. By adjusting the screen aperture, vibration frequency, or wind speed, the device can be adapted to the particle size requirements of different types of tea, ensuring efficient screening while reducing the loss of qualified tea leaves and guaranteeing screening accuracy and the quality of the finished tea. Current tea processing debris screening devices have many shortcomings. Some screen frames cannot achieve vibration screening, resulting in low screening efficiency. The device has poor sealing, and debris and dust can easily leak from the discharge port during screening, deteriorating the surrounding air environment and endangering personnel health. Existing technologies mostly use vibration in conjunction with screens, which lacks three-dimensional separation effect and makes it difficult to completely separate tea leaves, debris, and dust from the flat screen, seriously affecting the quality of the finished tea product. In some devices, tea leaves tend to pile up during feeding, limiting the screening area and causing uneven distribution, which can also lead to screen blockage. After screening, the tea leaves need to be manually cleaned, which is time-consuming and labor-intensive and can easily generate new debris. The screen body is fixed, making it difficult to adjust the tilt angle, and debris removal is incomplete, failing to meet the needs of mass production. Therefore, a new tea processing debris screening device is proposed to solve the above problems. Utility Model Content

[0003] To overcome the above shortcomings, this utility model provides a debris screening device for tea processing, which aims to improve the existing technology by making it easy to replace different types of filter screens, disassemble, clean, and quantitatively feed the tea leaves, preventing the tea leaves from piling up during feeding, limiting the screening area, causing uneven distribution, and also preventing screen blockage.
