Referring to fig. 4, the cleaning device 6 includes a movable ring 61, a cleaning sponge 68 is adhered to the outer wall of the movable ring 61, a first installation hole is formed through the left side of the top of the movable ring 61, a slide rod sleeve 66 matched with the slide rod 15 is arranged in the first installation hole, a second installation hole is formed through the right side of the top of the movable ring 61, a screw sleeve 67 matched with the screw 14 is arranged in the second installation hole, the slide rod sleeve 66 is sleeved on the periphery of the slide rod 15, the screw sleeve 67 is sleeved on the periphery of the screw sleeve 67, a fixed groove 62 is formed in the inner wall of the movable ring 61, a resistance thermometer 63 is arranged in the inner cavity of the fixed groove 62, an outer arc plate 64 is arranged on the inner wall of the movable ring 61 corresponding to the fixed groove 62, the outer arc plate 64 is movably connected with the movable ring 61 through a transverse bolt 65, after the fermentation work is completed, the screw 14 is driven to rotate through a, make activity ring 61 clear up the operation through outside clearance sponge 68 to fermentation cylinder 1 inner wall, can carry out real-time supervision to the inside temperature of fermentation cylinder 1 through resistance thermometer 63 on the activity ring 61, the monitoring temperature shows through display screen 23, when the temperature needs to be adjusted, rethread control panel 22 controls the temperature of electric heating rod 11 and electric heating plate 18 to the realization is through the temperature of electric heating rod 11 and electric heating plate 18 control fresh milk fermentation.
A method for a yoghourt fermentation device capable of replacing air in time comprises the following steps,
s1: after the fresh milk to be fermented is quantitatively measured by the
s2: after the fresh milk is stirred by the V-shaped
s3: gas generated in the fermentation process of the fresh milk in the fermentation tank 1 is discharged through the pressure relief device 5, the pressure relief device 5 can only discharge the gas generated in the fermentation tank 1 through pressure relief, and external gas cannot enter the inner cavity of the fermentation tank 1 through the pressure relief device 5 to pollute the fermented fresh milk;
s4: the temperature inside the fermentation tank 1 can be monitored in real time through the resistance thermometer 63 on the movable ring 61, the temperature is displayed through the
s5: after fermentation tank 1 fermentation, through opening ooff valve 3 on discharge pipe 2, the acidophilus milk that finishes with the fermentation is discharged, and after the fermentation work, drive
