▎ 摘　　要

NOVELTY - Black tea fermentation equipment has framework (11) is provided with magnetic movable doors (12) on the front and rear side walls, the left and right side walls of the framework are provided with wooden boards (13), and top of the framework (11) is covered with heat insulation panels (14) and these are assembled to form fermentation room (1). Inner bottom of the fermentation room is covered with PVC waterproof heating pad (2), and it has PVC waterproof layer (21), graphene electric heating film layer (22), tin foil polyurethane heat insulation layer (23) and wire mesh (24) from top to bottom. Wooden board on the left is installed with a speed-regulating exhaust fan (3), and wooden board on the right is connected with a humidifying pipe (4) and humidifying pipe is connected with an external humidifier, inner wall of the fermentation room is provided with temperature sensor (5) and humidity sensor (6), and bottom of the fermentation room is connected with a floor drain (7). USE - Black tea fermentation equipment. ADVANTAGE - The fermentation room has a stable structure and good sealing performance, and the arrangement of the magnetic movable door facilitates the access of tea leaves, floor drain is set at the bottom of the fermentation room, so that the condensed water is drained, and it is also convenient to clean the fermentation room. By setting the temperature sensor, humidity sensor, humidifying tube and speed-regulating exhaust fan, and connecting the humidifying tube to an external humidifier, the temperature and humidity in the fermentation room is monitored in real time through the temperature sensor and humidity sensor, and adjusted by the humidifier and speed-regulating exhaust fan, humidity of the fermentation room is adjusted by the graphene electric heating film to adjust the temperature and humidity inside the fermentation room, thereby improving the fermentation efficiency and the quality of tea. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of an angular configuration of black tea fermentation equipment. Adjustable speed exhaust fan (3) Framework (11) Magnetic movable door (12) Board (13) Insulation board (14)
