Wind path system of compound tea withering machine

Abstract

The invention provides a wind path system of a compound tea leaf withering machine. The system comprises a plurality of layers of frameworks arranged from high to low; the frameworks are uniformly divided into a plurality of withering areas from the front end to the rear end; each withering area is provided with a fan, or the multiple layers of vertically arranged withering areas share the same fan; a mesh belt of each withering area comprises an upper partition plate and a lower partition plate; inclined partition plates are arranged between the upper partition plates and the lower partition plates; and the fans supply wind from the side faces of the spaces between the upper partition plates and the lower partition plates, so that the wind can advance along the upper surfaces of the inclined partition plates. The wind path system of the compound tea withering machine is simple in structure, reasonable in design, high in working efficiency and small in occupied area, manpower is saved, it can be guaranteed that the wind can evenly penetrate through leaf layers, and it is guaranteed that the withering degree is even and consistent.

Description

technical field [0001] The invention relates to a tea air-drying device, in particular to an air duct system of a compound tea withering machine. Background technique [0002] The tea withering machine is a necessary equipment for the withering link in the tea production process. The withering machine mainly has two structures: single-layer and double-layer (multi-layer). [0003] Single-layer structure withering machines tend to be replaced by duplex (multi-layer) withering machines because of their small storage capacity per unit space. The structure of the single-layer withering machine is simple, and the large-volume fan directly blows the wind to the fresh leaves spread through the bottom air duct, so that the moisture of the withered leaves is relatively uniform. [0004] The compound withering machine adopts a multi-layer structure, and each layer uses a mesh belt to place tea leaves. Its production capacity is large and the layer spacing is small, so it is impossibl...
