Referring to fig. 6-9 again, a protective cover b21 is disposed outside the rack b11, the rack b11 is fixedly connected to the protective cover b21, a sliding groove is disposed outside the protective cover b21, the first gear b10 is disposed inside the protective cover b21, and one end of the rotating rod b9 penetrates through the sliding groove and extends into the protective cover b21, so that the protective cover b21 is used to protect the rack b11, and the situation that the lactic acid bacteria inside the fermentation tank b2 seriously affects the meshing between the rack b11 and the first gear b10 is avoided. In the embodiment, the bottom parts of the two reciprocating screw rods b6 are fixedly connected with a transverse plate b18, the top part and the bottom part of the moving block b7 are rotatably connected with connecting sleeves b12, the connecting sleeves b12 are sleeved outside the reciprocating screw rods b6, one connecting sleeve b12 is fixedly connected with the transverse plate b18, the other connecting sleeve b12 is fixedly connected with a connecting plate b5, and the connecting sleeves b12 are made of telescopic materials or structures, so that the reciprocating screw rods b6 are protected in real time through the connecting sleeves b 12. By arranging the connecting sleeves b12 at the upper part and the lower part of the moving block b7, when the moving block b7 moves, the connecting sleeves b12 are compressed or extended, so that the reciprocating screw rod b6 is protected, and meanwhile, the first gear b10 is more stably meshed with the rack b11 by the protective cover b21 arranged on the outer side of the first gear b 10.

Referring to fig. 6, 7 and 10 again, the top of the supporting frame b1 is fixedly connected with a heating box b15, the inner wall of the fermentation tank b2 is provided with an annular groove, a heating pipe b16 is arranged inside the annular groove, and both ends of the heating pipe b16 penetrate through the fermentation tank b2 and are fixedly connected and communicated with a heating box b15, so that the temperature of the lactic acid bacteria inside the fermentation tank b2 can be controlled by the heating pipe b 16. When temperature control of lactic acid bacteria in fermenter b2 is required, heating tank b15 is started to heat the internal water in heating tank b15, and the control valve is opened to allow constant water in heating tank b15 to flow into heating pipe b16, thereby controlling the temperature in fermenter b 2.

The foregoing shows and describes the general principles and broad features of the present invention and advantages thereof. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are described in the specification and illustrated only to illustrate the principle of the present invention, but that various changes and modifications may be made therein without departing from the spirit and scope of the present invention, which fall within the scope of the invention as claimed. The scope of the invention is defined by the appended claims and equivalents thereof.
