Wherein, the first stirring device 2, the brain-breaking device 4 and the yellow serofluid filtering device 5 can sequentially form a preparation position aligned up and down with the lower curdling barrel 1. In order to make the first stirring head 22 always float on the surface of the slurry, the first stirring head 22 may be configured in any suitable manner, for example, the first stirring head 22 may be configured to have a hollow structure, or may be made of a material with a density lower than that of the slurry, which is not limited by the present disclosure.

In addition, since the contact portion of the first stirring head 22 with the slurry is configured as a smooth curved surface, disturbance and damage to the jellied bean curd forming process during the stirring process can be avoided, thereby avoiding affecting the quality of the bean curd. In addition, this automatic curdling coagulation system still includes the device of breaing brain 4, yellow serofluid filter out device 5 and the device of appearing brain that set gradually in first agitating unit 2 low reaches to form the automatic curdling production line of serialization with first agitating unit 2 jointly, in this automatic curdling production line, both can set up a curdling bucket 1, also can set up a plurality of curdling buckets 1, and set up different parameters, select different production processes to different curdling buckets 1, thereby can produce the final product of different grade type, in order to improve the suitability of automatic curdling production system.
Since the liquid level of the slurry fluctuates up and down in a certain amount during the stirring, the position of the first stirring head 22 in the slurry can be adjusted by moving the first stirring rod 21 up and down in order to ensure that the first stirring head 22 always floats on the surface of the slurry.

s3: controlling the first stirring head 22 to stir the slurry;
s4: adding a coagulant into the curdling bucket 1;
s5: after the curdling is completed, the first stirring device 2 returns to the preparation position.
Through the technical scheme, in the curdling method provided by the disclosure, the smooth first stirring head 22 can be used for stirring the slurry, so that the disturbance and the damage to the bean curd jelly forming process in the stirring process are avoided, and the influence on the quality of the bean curd is avoided.
In order to meet the requirement that the slurry needs to be vertically stirred in some final products, the slurry curdling method can further comprise the following steps before the step S2:
s11: positioning the second stirring device 7 in a preparation position;
s12: controlling the second stirring head 72 to stir the slurry;

When vertical stirring of the slurry is required, steps S11 to S14 may be added between steps S1 and S2; when vertical stirring of the slurry is not required, step S2 may be performed directly after step S1. By adding the steps S11 to S14, the production requirements of various final products can be met, so that the application range of the curdling method is widened.
For some final products requiring a breach, the curdling method may further include a step after step S5:
s61: positioning the device 4 in said preparation position;
s62: the brain breaking device 4 enters the pulp inlet barrel 1 for breaking the brain;
s63: after the completion of the puncture, the puncture device 4 returns to the standby position.
When it is required to perform the jellied bean curd breaking on the shaped jellied bean curd, steps S61 to S63 may be added after step S5; when it is not necessary to perform the jellied bean curd forming process, the steps S61 to S63 may be skipped after the step S5 is performed, and the subsequent steps (e.g., the steps S71 to S73 described below, and/or the step S8 described below) may be performed directly.
For some end products that require yellow water filtering, the curdling method may further include a step after step S5:
s71: the yellow serofluid filtering device 5 is positioned at a preparation position;
s72: the yellow serofluid filtering device 5 enters the point serofluid barrel 1 to filter out the yellow serofluid;
s73: after the filtering out of the yellow serofluid is finished, the yellow serofluid filtering device 5 returns to the preparation position.
When filtering out of yellow serofluid is required, steps S71 to S73 may be added after step S5 or after step S63; when the filtering out of the yellow serofluid is not required, the subsequent step (e.g., step S8 described below) may be performed directly after the completion of step S5 or after the completion of step S63.
Further, the curdling method may further include, after the step S14 or S5 or S63 or S73, the step of:
s8: the bean curd jelly discharging device discharges bean curd jelly in the curdling barrel 1.
