Please select the most similar patent number from A, B, C and D. Which number is?
A tea leaf flavoring device, comprising an insulating layer, an electric heater, a machine body, a placement board, a net cover, a moisture sensor, a roller, a column, a driver, a secondary signal sensor, a slide rail, a pulley, a main control panel, a master controller, a drive key and a primary signal sensor. Tea leaves in the machine body are dried by means of the electric heater, and the pulley is controlled by means of the driver to drive the placement board to run up and down along the slide rail, thereby solving the problem of uneven heating of the tea leaves.
A: A forestry seedling apparatus comprising three fixed side boards (9) and a movable side board (7) installed on a bottom board (14). The fixed side boards (9) are placed on the three sides of the bottom board (14) while the movable side board (7) is placed on the fourth side thereof. The movable side board (7) is attached to the fixed side boards (9) by clasps (6). A sprinkler (5) is installed inside the movable side board (7) and a water storage tank (1) is provided outside the bottom board (14). The water storage tank (1) is connected to the sprinkler (5) by pipes (3) and a pump (4) is provided on the pipes (3). A main controller (12) is installed at the bottom end of the bottom board (14). Inside the bottom board (14) is installed a moisture sensor (13) connected to the main controller (12). The main controller (12) is also connected to the pump (4), and thus moisture can be measured with the moisture sensor (13). Moisture can be timely replenished to the seedling trays by the pump (4) to ensure water resources are evenly distributed.
B: A seed soaking apparatus, comprising: a hot water tank (9) installed at the right side of a seed soaking tank (14). A heating disc (10) is provided inside the hot water tank (9). The hot water tank (9) is connected to an inlet hole (6) by a hot water pipe (5). A hot water pump (8) is installed on the hot water pipe (5). A support (23) is provided at the bottom end of the seed soaking tank (14). A motor (7) is installed at the top end of the seed soaking tank (14) and connected to an axle (25). A mixing blade (26) is provided on the axle (25). A main control panel (18) having therein a main controller (16) is provided on the seed soaking tank (14). A temperature sensor (20) is provided in the seed soaking tank (14) and is connected to the master controller (16), and the master controller (16) is linked to the water pump (8). The temperature in the seed soaking tank (14) is measured by the temperature sensor (20). When the temperature is too high, information thereof is transmitted to the main controller (16), and the main controller (16) controls the pumping by the hot water pump (8) of hot water from the hot water tank (9) into the seed soaking tank (14), ensuring the effectiveness of seed soaking.
C: A new sunlight simulating tea leaf drying room, comprising a drying chamber, the ceiling of the drying chamber having at least one red light, at least one orange light, at least one yellow light, at least one green light, at least one blue light, at least one cyan light, at least one purple light, at least one ultraviolet disinfection light, at least one ultraviolet heating light and at least one ceramic heating light provided thereon, the wall or the ceiling of the drying chamber having an air inlet device and a ventilator fan arranged thereon, the drying chamber having a temperature sensor, a humidity sensor and an airing table arranged therein, and one side of the drying chamber having a control box arranged thereat.
D: A seed disinfection equipment, which primarily solves the problem wherein using methods of soaking in a liquid medicine or steaming easily deactivates seeds. A vertical column (21) is provided within an equipment body (20), a plurality of grooves (11) being provided on the column (21), while a plurality of seed holding grooves (13) are provided on a side of the column; an electrical heater (16) is provided in a seed holding groove (13), and a sponge layer (12) is provided in the seed holding tank (13), while an end of the seed holding tank (13) is provided within the groove (11) by means of a spring (18); a motor (19) is provided at a bottom portion of the groove (11), the motor being connected to the spring (18); a blower (3) is provided within the equipment body (20), while a medicine storage tank (1) is provided at an upper end of the equipment body (20), and a guide rail (5) is provided within the equipment body (20); a sprinkler (6) is provided on the guide rail (5), the sprinkler (6) being connected to the medicine storage tank (1) by means of a pipe (2), while a pump (22) is provided on the pipe (2), and the sprinkler (6) is connected to the guide rail (5) by means of a pulley (4). The sprinkler (6) drives forward and backward movement by means of the pulley (4) and seeds within the seed holding tank (13) may be driven, by means of the spring, to be disinfected, which may thus improve disinfection quality.
