Description

A kind of black tea drying system

technical field

The invention belongs to the technical field of processing equipment, and in particular relates to a black tea drying system.

Background technique

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

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 stove to smoke the tea leaves to have a strong smell of smoke, and it is difficult to control the baking temperature and drying time, which is prone to overheating. The phenomenon of baking, and the problem of high labor intensity and low production efficiency.

The present invention is realized in this way. The black tea drying system includes: a casing, an insulating layer, an air duct, an air outlet, a driving device, a display screen, a rotating shaft, a turntable, an infrared heating device, an inlet fan, a first temperature sensor, a second temperature Sensors, controllers, exhaust fans, casters, air inlets, drying room; the drying room is set inside the shell, with an air duct inside the shell, an insulation layer between the shell and the air duct, and an air outlet at the upper end of the air duct. An inlet fan is installed, an infrared heating device is installed at the lower end of the air duct, an air inlet is installed at the bottom of the infrared heating device, the driving device is installed at the bottom of the drying chamber, a rotating shaft is installed on the driving device, a turntable is installed on the rotating shaft, and the exhaust fan is installed on the top of the drying box , the first temperature sensor is installed at the corner of the bottom surface and the side of the drying chamber, the second temperature sensor is installed at the corner of the top surface and the side of the drying chamber, a display screen and a controller are installed on the outside of the shell, and the controller is respectively connected to the display screen and the second A temperature sensor, a second temperature sensor, an intake fan, an exhaust fan, and a driving device are connected, and casters are installed at the bottom of the housing.

Further, the turntable is provided with ventilation holes.

Further, the air outlet corresponds to the position of the turntable.

The infrared heating device heats the air, and the hot air is discharged into the drying box through the inlet fan. The black tea is placed on the turntable, and the driving device drives the turntable to rotate, so that the black tea is dried evenly. The temperature of different positions inside the box will transmit the temperature signal to the controller. If the temperature difference is too large, the controller will increase the power of the infrared heating device and increase the speed of the intake fan to generate more heat.

The advantages and positive effects of the present invention are: the dark tea drying system fully decomposes the caffeine and caffeine in the tea leaves, so that the contents of the tea leaves can be fully converted into active ingredients such as theaflavins, thearubigins, and tea polysaccharides. Multi-layer drying, heating and drying evenly, fast drying speed, high efficiency, good drying quality of black tea, no smoky taste, the taste of the baked black tea is mellow, the soup color is red and yellow, and the aroma is tangy.
