Drying device for green tea

Abstract

The invention discloses a drying device for green tea. The drying device comprises a drying chamber and a conveyor belt in the drying chamber, wherein clamping grooves are connected to the surface of the conveyor belt; drying boxes are fit in the clamping grooves in an embedding manner; the drying device further comprises screening mechanisms; each of the screening mechanisms comprises a screen mesh and a rotating shaft; the screen meshes are arranged in the middles of the drying boxes; the screen meshes are parallel with the bottom surfaces of the drying boxes; each of the screen mesh divides the corresponding drying box into a material containing box and a residue containing box; a vibrator is connected to the corresponding screen mess; the rotating shaft is perpendicular to the corresponding screen mesh; the rotating shaft and the screen mesh are connected in a rotating manner through a bearing; helical blades are arranged on the rotating shaft; an electric motor which drives the rotating shaft to rotate is connected to the corresponding rotating shaft; the green tea is in contact and rubs with each other, and crisp edges of the green tea are knocked down during the rubbing process; the edges which are knocked down fall off through the gap of a green tea leaf pile and fall onto the surface of the corresponding screen mesh; because the vibrator is connected to the corresponding screen mesh and drives the corresponding screen mesh to vibrate, the edges fall off through the apertures of the screen meshes and fall into the residue containing boxes; and the crisp edges produced during the drying process of the green tea leaves are separated from the green tea during the drying process of the green tea.

Description

technical field [0001] The invention relates to the technical field of green tea processing, in particular to a drying device for green tea. Background technique [0002] Green tea (Green Tea) is one of the main teas in China. It refers to a drink made from the new leaves or buds of the tea tree without fermentation, and through processes such as greening, shaping, and drying. The color of its finished product and the tea soup after brewing mostly preserve the green style of fresh tea leaves. Drinking green tea regularly can prevent cancer, reduce fat and lose weight, and can also reduce the damage of nicotine to smokers. [0003] The processing of green tea includes the steps of withering, greening, kneading and drying. Among them, when drying, the current common method is to place the greened tea leaves on the conveyor belt, and then transfer them to the drying room through the conveyor belt for drying. When using this method for drying, because the moisture inside the t...
