DETAILED DESCRIPTION

[0016] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of protection of the present application.

[0017] Embodiment one: please refer to Figures 1-7 and Figure 10The application provides the following technical scheme: a food-grade temperature-controlled stirring continuous fermentation system, in order to solve the problem that the fermentation gas required by the conventional rotary overturning working structure rises to the upper end of the inside of the equipment according to the fermentation state, temperature and pressure, and cannot effectively and continuously contact the reactant at the bottom, the application discloses that the upper end of a fermentation tank body 1 is provided with a driving motor assembly, the output end of the driving motor assembly is connected with a driving butt joint shaft 2; the upper end of the fermentation tank body 1 is provided with an embedded butt joint rod 4, the lower end of the embedded butt joint rod 4 is connected with a nested butt joint assembly 3, the lower end of the nested butt joint assembly 3 is provided with a butt joint piece 5, the inner side of the butt joint piece 5 is fixedly connected with a return spring 6, the return spring 6 and the inner side of the nested butt joint assembly 3 are connected with each other, a self-adapting guide structure is arranged between the nested butt joint assembly 3 and the embedded butt joint rod 4, and the self-adapting guide structure is used for controlling the heat conduction state in the fermentation tank body 1.

[0018] The adaptive guide structure is provided with a resistance reserved part 8, which is nested and connected to the inner side of the lower end of the nested connecting assembly 3. The outer side of the resistance reserved part 8 is connected with a reserved steel wire 7, which penetrates along the inner side of the lower end of the nested connecting assembly 3, and the end of the reserved steel wire 7 is connected with the outer side of the resistance connecting part 5. The upper end of the nested piston part 9 is nested and connected to the inner side of the lower end of the built-in connecting rod 4, and the lower end of the nested piston part 9 is nested and connected to the inner side of the lower end of the nested connecting assembly 3. The inner side of the built-in connecting rod 4 is provided with a gas storage cavity 10, and the lower end of the gas storage cavity 10 is provided with a reserved through hole 11, and the inner side of the reserved through hole 11 is provided with a filter screen structure. The outer side of the upper end of the built-in connecting rod 4 is connected with a horizontal supply pipe 17, and the inner side of the lower end of the horizontal supply pipe 17 is provided with a horizontal reserved hole 18. The driving connecting shaft 2 drives the nested connecting assembly 3 at the lower end to rotate and connect along the lower end of the built-in connecting rod 4. When the resistance connecting part 5 on the outer side of the built-in connecting rod 4 is pressed, the compression return spring 6 slides along the inner side of the nested connecting assembly 3. The resistance connecting part 5 forms a vertical traction structure between the resistance reserved part 8 through the reserved steel wire 7. When the resistance reserved part 8 is forced to move upward, it pushes the nested piston part 9 at the lower end to move upward synchronously. When the nested piston part 9 moves upward along the inside of the gas storage cavity 10 to be away from the reserved through hole 11, the reserved through hole 11 and the gas storage cavity 10 are in a closed state of non-connection. When the nested piston part 9 continuously moves upward, the hot gas stored in the inner side of the gas storage cavity 10 is supplied and discharged downward through the horizontal supply pipe 17.

According to the fermentation state of the raw materials inside the equipment, the resistance connecting part 5 on the outer side of the nested connecting assembly 3 will be pressed inward, and at the same time, the resistance connecting part 5 will drive the resistance reserved part 8 to work vertically through the reserved steel wire 7, and then press the nested piston part 9 at the upper end synchronously, so that the nested piston part 9 reciprocally moves along the inside of the gas storage cavity 10, thereby storing the reaction hot gas inside, and supplying and discharging it downward through the horizontal supply pipe 17. When the nested piston part 9 moves upward along the inside of the gas storage cavity 10 to be away from the reserved through hole 11, the reserved through hole 11 and the gas storage cavity 10 are in a closed state of non-connection. At this time, the stored hot gas in the inside of the gas storage cavity 10 will be effectively discharged, and after the nested piston part 9 is reset to the lower end of the reserved through hole 11, the inside of the gas storage cavity 10 can continue to store hot gas. The conventional continuous rotation and turning structure is avoided, and the fermentation gas required by the fermentation state inside the equipment is continuously and effectively circulated downward, so as to avoid the influence of the state of air pressure and temperature on the accumulation in the upper end of the equipment, thereby maintaining the uniform and effective continuous contact with the reaction materials at the bottom, and ensuring the overall fermentation quality.

The auxiliary moving structure is provided with a nested contact piece 12, which is nested and butt jointed on the inner side of the upper end of the built-in butt joint rod 4, and the lower end of the nested contact piece 12 corresponds to the upper end of the nested piston piece 9. The upper end of the built-in butt joint rod 4 is butt jointed with a built-in liquid bag 13, and the lower end of the built-in liquid bag 13 corresponds to the upper end of the nested contact piece 12. The outer side of the built-in liquid bag 13 is butt jointed with a supply hose 14, and the supply hose 14 penetrates along the inner side of the upper end of the built-in butt joint rod 4. The upper end of the built-in butt joint rod 4 is fixedly connected with a butt joint connecting piece 16, and the inner side of the butt joint connecting piece 16 is fixedly connected with a corrugated arc liquid bag 15, and the corrugated arc liquid bag 15 is butt jointed with the inner side of the upper end of the fermentation tank body 1. The upper end of the built-in butt joint rod 4 is butt jointed with a torsion spring assembly. The nested contact piece 12 is synchronously pressed during the upward movement of the nested piston piece 9, and the nested contact piece 12 performs negative pressure treatment on the built-in liquid bag 13. The built-in liquid bag 13 supplies and expands the inside of the corrugated arc liquid bag 15 through the supply hose 14. During the pressure expansion of the corrugated arc liquid bag 15, the built-in butt joint rod 4 is driven to rotate along the inner side of the upper end of the fermentation tank body 1 through the butt joint connecting piece 16. The nested piston piece 9 contacts the contact force of the contact reserved piece 8, and the upper end of the nested piston piece 9 synchronously presses the nested contact piece 12 during the continuous upward movement along the inner side of the built-in butt joint rod 4, so that the nested contact piece 12 extrudes the built-in liquid bag 13, and the built-in liquid bag 13 supplies and expands the inside of the corrugated arc liquid bag 15 through the supply hose 14. The pressure-expanded corrugated arc liquid bag 15 deforms along the fixed arc-shaped groove, so that the built-in butt joint rod 4 and the transverse supply pipe 17 are driven to rotate along the inner side of the upper end of the fermentation tank body 1 through the butt joint connecting piece 16, thereby forming a multi-range hot gas supply settlement process on the inner side of the upper end of the fermentation tank body 1. At the same time, the gas accumulated in the inner side of the upper end of the fermentation tank body 1 is pressed downward by the supply gas flow, so that it efficiently contacts the reaction material and improves the fermentation quality.
