[0038] A working method of an automatic tea frying machine comprises the following steps:

[0039] Preheating step: The bottom outer wall of the cylinder 3 is heated by the heating component 18, and the temperature of the heating component 18 is detected by the temperature sensor 27. The temperature sensor 27 transmits the detected temperature to the control host 13 through an electrical signal, and the control host 13 controls the temperature of the heating component 18 to be kept stable and constant;

[0040] Leveling step: the support plate 1 is driven to move by the servo electric cylinder 10, and the tilt angle of the support plate 1 is detected by the tilt sensor 1 11 and the tilt sensor 2 12. The tilt sensor 1 11 and the tilt sensor 2 12 transmit the tilt angle information to the control host 13 through an electrical signal, and the servo electric cylinder 10 is controlled by the control host 13 to work, so that the support plate 1 reaches a horizontal state, and the support plate 1 is driven to rotate by the servo electric cylinder 10, so that the tea leaves inside the cylinder 3 are conveniently unloaded in an inclined manner.

A working method of an automatic tea frying machine, comprising the automatic tea frying machine according to any one of claims 1 to 8, characterized in that: The following steps are involved: Preheating step: heating the bottom outer wall of the cylinder (3) by means of a heating component (18), detecting the temperature of the heating component (18) by means of a temperature sensor (27), transmitting the detected temperature to a control host (13) by means of an electrical signal, and controlling the temperature of the heating component (18) by means of the control host (13) to maintain a stable and constant temperature; Leveling step: driving the support plate (1) to move by means of a servo electric cylinder (10), and detecting the tilt angle of the support plate (1) by means of a first tilt sensor (11) and a second tilt sensor (12), wherein the first tilt sensor (11) and the second tilt sensor (12) transmit the tilt angle information to a control host (13) through electrical signals, and the control host (13) controls the servo electric cylinder (10) to work, so that the support plate (1) reaches a horizontal state; Loading step: opening the protective cover (32), placing tea leaves into the interior of the cylinder (3), and sealing the cylinder (3) with the protective cover (32); Stir-frying step: the driving gear (5) is driven to rotate by the motor (7), and the rotation of the driving gear (5) drives the driven gear (6) and the rotating shaft (4) to rotate, so that the rotating shaft (4) drives the mounting frame (14) to rotate, and when the mounting frame (14) rotates, the side gear (21) is meshed with the inner gear ring (15) to rotate, and then the side gear (21) drives the stirring shaft (16) to rotate, so that the blade plate (17) on the stirring shaft (16) turns the tea leaves inside the cylinder (3), and at the same time, the tea leaves are rolled by the rolling plate (35); Unloading step: After the tea leaves are roasted, the servo electric cylinder (10) drives one end of the support plate (1) to rotate downward, so that the cylinder (3) is tilted, and the tea leaves inside the cylinder (3) flow out from the discharge hopper (24).

10. The working method of the automatic tea frying machine according to claim 9, characterized in that: In the frying step, the pulse valve (34) is controlled by the control host (13), and compressed air is filled into the interior of the horizontal tube (30) through the air pump (33), and the air is blown out from the air outlet (28) in the form of pulses.
