[0022] Embodiment 1

[0023] The embodiment provides a fermentation device with sterilization function, specifically as follows Figures 1-6As shown, including fermentation tank, the stirring part, sterilization part is installed on the fermentation tank, the stirring part includes stirring paddle, stirring motor 104 and planetary gear drive unit, the output end of the stirring motor 104 is in transmission connection with the input end of the planetary gear drive unit, and the output end of the planetary gear drive unit is in transmission connection with the stirring paddle;The planetary gear drive unit includes fixed ring 113, sun gear 115, planetary gear 114, synchronous wheel 117, the fixed ring 113 is fixedly installed on the fermentation tank, the sun gear 115 is installed on the output end of the stirring motor 104, the sun gear 115 is installed on the central shaft 110, the central shaft 110 is connected with a stirring paddle, the central shaft 110 is rotatably connected with the planet carrier 118, the planet carrier 118 is rotatably connected with the planet shaft 109, the planet shaft 109 is connected with a stirring paddle, the planetary gear 114, synchronous wheel 117 are all fixedly installed on the planet shaft 109;The fixed ring 113 is provided with arc-shaped meshing area 1131 and tooth meshing area 1132 arranged alternately, the synchronous wheel 117 is provided with arc-shaped area 1171 and tooth area 1172, the number of teeth of the sun gear 115 is greater than the number of teeth of the planetary gear 114;The fermentation tank is provided with feed inlet, discharge port and corresponding valve 106.

[0024] When the stirring part works, the stirring motor 104 is started, and then drives the sun gear 115 to rotate. Since the planetary gear 114 is engaged with the sun gear 115, and the teeth area 1172 on the synchronous wheel 117 is engaged with the tooth engagement area 1132 on the fixed ring 113, the planetary gear 114 rotates and revolves. When the planetary gear 114 revolves, the synchronous wheel 117 also rotates and revolves. When the synchronous wheel 117 rotates to the arc-shaped area 1171 and the arc-shaped engagement area 1131, the planetary gear 114 cannot continue to revolve, so the planetary gear 114 driven by the sun gear 115 only rotates. Similarly, the synchronous wheel 117 only rotates. When the synchronous wheel 117 rotates to the tooth area 1172 and the tooth engagement area 1132, the planetary gear 114 starts to revolve and rotate again. In this way, the planetary shaft 109 rotates continuously and revolves intermittently. Since the number of teeth of the sun gear 115 is greater than the number of teeth of the planetary gear 114, when the arc-shaped area 1171 and the arc-shaped engagement area 1131 are matched, the rotation speed of the sun gear 115 is less than that of the planetary gear 114. At this time, the planetary shaft 109 rotates faster than the central shaft 110, so when the material is stirred, the vortex formed by the material is mainly based on the planetary shaft 109. When the tooth area 1172 and the tooth engagement area 1132 are engaged, the planetary gear 114 starts to rotate and revolve, so the rotation speed of the planetary gear 114 starts to be slower than that of the sun gear 115. At this time, the planetary shaft 109 rotates slower than the central shaft 110, so when the material is stirred, the vortex formed by the material is mainly based on the central shaft 110. By adjusting the periodic change of the rotation speed of the planetary shaft 109, the material not only receives the stirring effect of the rotation of the planetary shaft 109, the rotation of the central shaft 110, and the revolution of the planetary shaft 109, but also receives the stirring effect of the vortex formed by the material due to the change of the stirring speed. By superimposing multiple stirring effects, the mixing efficiency of the material is greatly improved, not only saving the mixing time but also improving the mixing effect.

Since the rotation directions of the planetary shaft 109 and the central shaft 110 are opposite, the paddle 116 on the planetary shaft 109 is staggered with the paddle 116 on the central shaft 110, so that a shearing action can be formed during stirring, further improving the stirring quality and rate.
