Currently, traditional wine fermentation equipment has the following problems in practical application: Traditional fermentation equipment mostly adopts an intermittent fermentation mode. After completing the fermentation of a batch of raw materials, the equipment needs to stop running to carry out a series of operations such as discharging, cleaning, and loading, resulting in frequent start-up and shutdown of the equipment. The start-up and shutdown of the equipment not only consumes a lot of energy, resulting in energy waste, but also interrupts the fermentation process and makes the microbial growth and metabolic environment unstable. After reloading, microorganisms need a certain amount of time to adapt to the new environment, the fermentation rate decreases, the overall fermentation cycle is extended, and continuous and efficient fermentation cannot be achieved, which seriously affects production efficiency. In addition, because the slag is mixed with the liquid for fermentation, the slag content of the liquid is relatively high, which increases the subsequent processing and production costs; when discharging the slag, the slag often contains a large amount of liquid that is not fully utilized, and the slag content is high, resulting in waste of raw materials and reducing the overall utilization rate of the raw materials.

[0018] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0019] See also Figure 1-4 As shown, a filtering, pressing and fermentation reaction device for making corn straw wine includes a tank body 4, a spiral elevator 17 and a pressing mechanism 11. The bottom end of the tank body 4 is fixedly connected to an inverted conical filter screen 19, which divides the tank body 4 into two upper and lower chambers. The top of the tank body 4 is connected to a feed pipe 1 connected to the upper chamber, and the bottom end of the tank body 4 is connected to a discharge pipe 8 connected to the lower chamber; the spiral elevator 17 is arranged inside the tank body 4, and the feed end of the spiral elevator 17 is located on the inner side of the bottom end of the inverted conical filter screen 19. The spiral elevator 17 is used to lift the material above the inverted conical filter screen 19 upward; the pressing mechanism 11 includes a conical dewatering cylinder 25, the large diameter end of the conical dewatering cylinder 25 is connected to the discharge port of the spiral elevator 17, and the small diameter end of the pressing mechanism 11 is connected to a slag discharge pipe 24.

[0020] During alcohol fermentation, fermentation raw materials are added to the tank body 4 through the feed pipe 1, and the fermentation raw materials fall above the inverted conical filter 19, and are separated from the discharge pipe 8 by the inverted conical filter 19. Under the action of the inverted conical filter 19, the slag content in the liquid discharged from the discharge pipe 8 is reduced; during the fermentation process, the slag located at the bottom of the inverted conical filter 19 is regularly lifted upward by the spiral elevator 17, and new fermentation raw materials are added to the tank body 4 through the feed pipe 1, so as to circulate and enable it to continue fermentation; the slag lifted upward by the spiral elevator 17 is pressed out of the liquid in the tank body 4 under the action of the conical dehydration cylinder 25 to reduce the water content of the slag.

[0021] To facilitate fermentation temperature control, a jacket 5 is fixedly attached to the outside of the tank body 4. The upper and lower ends of the jacket 5 are respectively connected to a liquid outlet pipe 6 and a liquid inlet pipe 7. Hot or cold water is circulated into the jacket 5 through the liquid outlet pipe 6 and the liquid inlet pipe 7 to control the temperature inside the tank body 4 within a suitable range.

[0022] Because alcohol fermentation is the process in which yeast decomposes glucose to produce ethanol and carbon dioxide under anaerobic conditions, to prevent oxygen from entering the tank body 4 when adding fermentation raw materials and affecting alcohol production, a first sealing gate valve 15 and a second sealing gate valve 16 are fixedly connected to the feed pipe 1 at intervals. A temporary storage chamber is formed between the first sealing gate valve 15 and the second sealing gate valve 16. The temporary storage chamber is connected to a vent pipe 13 and an exhaust pipe 14. The end of the vent pipe 13 away from the temporary storage chamber is connected to the tank body 4. Specifically, both the vent pipe 13 and the exhaust pipe 14 are equipped with air valves.

[0023] When adding fermentation raw materials, connect the exhaust pipe 14 to the vacuum pump, open the first sealing gate valve 15, place the fermentation raw materials in the temporary storage chamber, then close the first sealing gate valve 15, and use the vacuum pump to extract the air in the temporary storage chamber to reduce the oxygen content therein, then close the air valve on the exhaust pipe 14 and open the air valve on the ventilation pipe 13 to connect the temporary storage chamber with the tank body 4 to balance the pressure difference between the two chambers so that the second sealing gate valve 16 can be opened. After the second sealing gate valve 16 is opened, the fermentation raw materials in the temporary storage chamber fall into the tank body 4, and then close the second sealing gate valve 16.

[0024] In order to make the feeding more uniform, there are multiple feeding pipes 1, and the multiple feeding pipes 1 are evenly distributed along the circumference of the tank body 4.

[0025] In some embodiments, the screw elevator 17 includes a mesh drum 18, the middle of which is rotatably connected to a shaft 20 driven by a motor 10, and a spiral blade 26 is fixedly connected to the outer side of the shaft 20. By using the mesh drum 18 as the lifting drum, it can still exchange liquid with the outside of the screw elevator 17 during the lifting process.

[0026] To improve the sealing performance of the pressing mechanism 11, a sealing cylinder 31 is provided on the outside of the conical dewatering cylinder 25. The sealing cylinder 31 is fixedly connected to the tank body 4. An overflow trough 28 is fixedly connected to the outside of the bottom end of the sealing cylinder 31. The sealing cylinder 31 communicates with the overflow trough 28 through a drain port 27. The liquid squeezed by the pressing mechanism 11 flows into the overflow trough 28 through the drain port 27. The overflow trough 28 seals the bottom end of the sealing cylinder 31, thereby improving the sealing performance. Preferably, a storage bin 12 is provided at the top of the tank body 4. The storage bin 12 is provided with a slag discharge port, and a sealing cover 9 is provided at the slag discharge port. The storage bin 12 is provided to facilitate the collection of squeezed materials.

[0027] To further reduce the moisture content of the discharged slag, a slag discharge pipe 24 is sleeved on the outside of the rotating shaft 20. A pressure plate 23 is provided at the discharge port of the slag discharge pipe 24, which is slidably connected to the rotating shaft 20. A pressure spring 22 is provided on the side of the pressure plate 23 away from the slag discharge pipe 24. The end of the pressure spring 22 away from the pressure plate 23 is fixedly connected to the rotating shaft 20 via a spring seat 21. Under the cooperation of the pressure spring 22 and the pressure plate 23, pressure is applied to the slag, increasing the discharge pressure, thereby further reducing the moisture content of the discharged slag.

[0028] Specifically, the tank body 4 is connected to a refill tube 2, a pressure relief valve 3, a liquid level sensor 29, and a temperature sensor 30. As fermentation continues, the alcohol concentration in the tank body 4 increases. After a portion of the fermented liquid is discharged through the drain tube 8, an equal amount of water is added through the refill tube 2 to maintain the liquid level in the tank body 4. The liquid level sensor 29 is provided to monitor the liquid level in the tank body 4. As fermentation progresses, carbon dioxide is continuously produced, and the pressure in the tank body 4 continues to rise. The pressure relief valve 3 is provided to relieve this pressure. The temperature sensor 30 is provided to monitor the temperature in the tank body 4 for temperature control.

[0029] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
