A kind of black tea drying system

Abstract

The invention discloses a drying system for dark green tea. A drying room is arranged in a shell; the inner side of the shell is provided with an air duct; an insulating layer is arranged between the shell and the air duct; air outlets are formed in the upper end of the air duct; an air intake fan is arranged in the air duct; the lower end of the air duct is provided with an infrared heating device; an air inlet is formed in the bottom part of the infrared heating device; a driving device is arranged at the bottom part of the drying room; the driving device is provided with a revolving shaft; the revolving shaft is provided with turnplates; an exhaust fan is arranged at the top part of the drying room; a first temperature sensor is arranged at the corner of the bottom face and the side face of the drying room; a second temperature sensor is arranged at the corner of the top face and the side face of the drying room; the outer side of the shell is provided with a display screen and a controller; the bottom part of the shell is provided with castors. The drying system for the dark green tea has the advantages that components in the tea are fully decomposed, the tea is heated and dried evenly, the drying speed is fast, the drying efficiency is high, the drying quality of the dark green tea is good, and the tea does not have a smoky flavor.

Description

technical field [0001] The invention belongs to the technical field of processing equipment, and in particular relates to a black tea drying system. Background technique [0002] Black tea is rich in nutrients, and helps digestion and fat-reducing weight loss. Dark tea drying is an important step in the production of dark tea. The drying process directly affects the quality of dark tea. The existing dark tea drying mostly uses Qixing stove for drying, and firewood is used as the heat source. During the burning of firewood, a large amount of The carbon monoxide in the smoked tea leaves has a strong smell of smoke. There is only one roaster on the hearth of the Qixing stove, and the tea leaves are about 40 cm away from each other. , Low production efficiency. Contents of the invention [0003] The purpose of the embodiment of the present invention is to provide a black tea drying system, aiming to solve the problem that the existing dark tea drying method adopts Qixing sto...
