Tea drying and dust removing device

Abstract

The invention discloses a tea drying and dust removing device, and belongs to the field of tea processing. The device comprises a box body, a draught fan, a feeding pipe, and a discharging pipe; the draught fan and the feeding pipe are both mounted on a top plate of the box body; the bottom of the box body is funnel-shaped; the discharging pipe is mounted at the bottom end of the box body; a filter cylinder is arranged at the upper side of the interior of the box body; the filter cylinder comprises a fixed filter cylinder and two overturning filter cylinders; the two overturning filter cylinders are symmetrically distributed at the two sides of the fixed filter cylinder and are rotationally combined with the fixed filter cylinder; the top of the fixed filter cylinder and the bottom of thedraught fan are installed; the draught fan is communicated with the interior of the fixed filter cylinder; and the diameters of the ends, close to the fixed filter cylinder, of the two overturning filter cylinders are greater than the diameters of the other ends. According to the scheme, the tea drying and dust removing device can achieve convenient and efficient feeding, drying, dust removing, deslagging and discharging operation on tea leaves, the operation process is high in automation degree and short in consumed time, and the purity of discharged tea leaves is high.

Description

technical field [0001] The invention relates to the technical field of tea processing, in particular to a tea drying and dust removal device. Background technique [0002] Drying is an essential step in the production and processing of tea. During the drying process, the tea leaves are in the drying box, and the moisture in the tea leaves is removed at a high temperature. If the moisture in the drying box cannot be discharged in time, it will decrease Drying efficiency; In addition, tea ash and debris will be produced during the tea drying process, if the tea ash and debris are not discharged, the quality of the tea will be affected. [0003] After retrieval, Chinese Patent No. CN 109953134 A discloses a tea drying and dedusting device, which includes a heating dedusting chamber, a drying drum, and an air supply pipe. An opening is arranged on the top of the heating dedusting chamber, and a cover plate corresponding to the opening is provided. The inner wall of the drying d...

AI Technical Summary

Problems solved by technology

[0005] 1. When the tea leaves are inserted into the device, it is necessary to align the opening with the feeding port, and the tea can be added after the alignment. However, the alignment operation is difficult to grasp the accuracy, so it takes a long time. In addition, the feeding port needs to be rotated to The lower side can pour the tea leaves;

[0006] 2. Impurities such as filtered dust and slag are discharged from the device through the discharge port on the lower side. During the process, the impurities will be adsorbed on the inner wall of the device and the inner wall of the discharge port. Therefore, when the tea leaves are discharged in the later stage, the filtered tea leaves There will still be a large part re-doped with the impurities adsorbed on the inner wall of the device and the inner wall of the discharge port, so the dust removal effect of tea leaves is low;

[0007] 3. When filtering tea leaves, the debris will cause the filter holes to be blocked. Due to the lack of corresponding cleaning and dredging means, the dust removal and filtration effects of the device will be reduced when the device is continuously used.
