[0024] The utility model provides a rake type defoamer 3 which rotates synchronously with the agitator 2, so that the rake type defoamer 3 can remove the foam in its rotating area during the rotation process. When a large amount of foam appears and is higher than the rake type defoamer 3, the foam can be pressed down by the pushing mechanism 6 which moves up and down reciprocatingly, so that the foam enters the moving area of the rake type defoamer 3, thereby ensuring that the foam generated during the fermentation process will not enter the feeding pipe 5 and overflow. The entire defoaming process adopts mechanical defoaming, which can reduce the production cost of probiotic fermentation.
[0025] It should be noted that a motor for driving the agitator 2 to rotate is provided on the top of the tank cover 12, and the tank body 11 is also provided with a gas supply mechanism, a temperature control mechanism, and a discharge mechanism required for fermentation. These are mature existing technologies and will not be elaborated on here.
[0026] In an embodiment, the stirrer 2 is composed of a central shaft rotatably arranged on the tank cover 12 and a plurality of stirring blades arranged on the central shaft.

[0028] In this way, when the stirrer 2 rotates, the guide block 63 moves in the thread groove, and the pushing plate 61 is driven by the guide block 63 to move up and down due to the restriction of the guide rod 62, so that the foam pressing operation can be completed reciprocatingly, and no additional power is needed, which can improve the synchronization of defoaming with the rake defoamer 3.
[0029] In an embodiment, the top of the pushing plate 61 is provided with a sink groove for guiding the liquid above the pushing plate 61 to flow to the center of the pushing plate 61, the bottom of the pushing plate 61 is provided with a plurality of liquid discharge holes communicated with the sink groove for discharging the liquid and gas at the center of the pushing plate 61, the bottom of the tank cover 12 is provided with a pressing plate 64 located in the annular partition plate 4 and matched in size with the sink groove, and the pushing plate 61 abuts against the pressing plate 64 when it moves to the upper limit position.
[0030] In this way, when the pushing plate 61 moves to the lower limit position, a part of the foam on the pushing plate 61 pressed by the pushing plate 61 can enter the sink groove, and then when the pushing plate 61 moves to the upper limit position, the foam in the sink groove contacts the pressing plate 64, so that the internal foam is broken and separated into gas and liquid which are discharged from the liquid discharge holes, thereby improving the defoaming efficiency and further avoiding the overflow of foam.
