c. an operator controls the controller (40) by using the control key (18), the controller (40) controls the first water pump (8) to be started, after being filtered by the ventilation net (38), the liquid containing spirulina reaches the inside of the second connecting pipe (9), then enters the inside of the supporting frame (22) through the first connecting pipe (7), the movable pipe (5) and the shunt pipe (21), and the cleaning pipe (23) is provided with a small-hole filter screen and can separate algae mud from a culture solution;

d. an operator controls the controller (40) by using the control key (18), the controller (40) opens the first electromagnetic valve (25), the culture solution enters the collecting box (10), after a certain time, the first electromagnetic valve (25) is closed, the heating pipe (20) controls the third water pump (27) to be started, the second electromagnetic valve (30) is opened, the clean water in the water storage box (2) is filled into the processing box (1), after the processing box (1) is filled, the third water pump (27) is stopped, the second electromagnetic valve (30) is closed, the controller (40) controls the stirring motor (24) to be started, the stirring blade (26) starts to rotate, the algae mud in the cleaning pipe (23) is cleaned, after the cleaning is finished, the stirring motor (24) is stopped, and the controller (40) controls the third electromagnetic valve (31) to be opened, the clean water flows out;

e. an operator controls the controller (40) by using the control key (18), the controller (40) controls the heating pipe (20) to start, the temperature inside the treatment box (1) rises, the temperature sensor (28) monitors the temperature and sends the temperature to the processor (41), the processor (41) controls the controller (40), when the temperature is enough, the controller (40) controls the heating pipe (20) to stop, the controller (40) controls the fourth electromagnetic valve (34) and the exhaust fan (33) to be opened, the water vapor inside the treatment box (1) is exhausted, the fourth electromagnetic valve (34) and the exhaust fan (33) are stopped, the controller (40) controls the display screen (17) to display completion, and then the operator controls the controller (40) by using the control key (18), the controller (40) controls the rotating motor (6) to rotate, the sealing cover (4) is removed, and dried spirulina is taken out.
