Tea dust-removal device with air separation structure

Abstract

The invention discloses a tea dust-removal device with an air separation structure. The tea dust-removal device comprises a table-shaped base, the upper portion of the table-shaped base is provided with a primary screening device, and the top of the primary screening device is provided with a material input mouth, the primary screening device is internally provided with a drying device, the innerbottom of the primary screening device is provided with a pumping direction motor, the side surface of the bottom of the primary screening device is provided with a dust collecting device, the primaryscreening device is connected with an air separation device through a hopper sliding passage, and the side surface of the table-shaped base is provided with a dust collecting drawer group. By means of the tea dust-removal device with the air separation structure, a two-segment type dust-removal method is realized, and by means of the primary screening device, most impurities in tea are rapidly and effectively separated.

Description

technical field [0001] The invention relates to the field of tea, in particular to a tea dust removal device with winnowing structure. Background technique [0002] Tea is made by picking the buds or new leaves of tea trees as raw materials, and it is made through a series of production processes. The tea processing process must go through the steps of rolling and drying, and rolling usually uses manual rolling or rolling and rolling. It is inevitable to produce broken pieces and dust, which will affect the quality of tea leaves. Therefore, usually tea leaves need to be dedusted. The usual dedusting method is to use vibration and screen dust removal methods. However, since tea leaves are usually stored in piles, it is still impossible to completely remove dust during the vibration dedusting process. The dust and dust are removed, and the removal effect is poor. Tea sorting is a sorting method that uses wind to remove impurities such as sand, dust, and green and yellow floati...

[0002] Tea is made by picking the buds or new leaves of tea trees as raw materials, and it is made through a series of production processes. The tea processing process must go through the steps of rolling and drying, and rolling usually uses manual rolling or rolling and rolling. It is inevitable to produce broken pieces and dust, which will affect the quality of tea leaves. Therefore, usually tea leaves need to be dedusted. The usual dedusting method is to use vibration and screen dust removal methods. However, since tea leaves are usually stored in piles, it is still impossible to completely remove dust during the vibration dedusting process. The dust and dust are removed, and the removal effect is poor. Tea sorting is a sorting method that uses wind to remove impurities such as sand, dust, and green and yellow floating leaves in tea. There are still many problems in modern tea dust removal and winnowing devices. For example, the feeding port of the traditional winnowing machine adopts the bucket-shaped feeding method. When there are more tea leaves on the feeding board, the outflow speed of the tea leaves on the feeding board is higher. When there are fewer tea leaves on the feeding board, The outflow speed of tea leaves is low, and the outflow speed of tea leaves cannot be automatically controlled, so the sorting quality of tea leaves is not high, and a large amount of dust is often generated when feeding materials, which will cause great harm to human health and the environment.
