Description

Technical Field

[0001] The utility model relates to the technical field of fermentation equipment, in particular to an alcohol fermentation device. Background Art

[0002] As we all know, alcohol fermentation has a large number of applications in the alcohol industry, brewing industry and food industry. Wine, fruit wine, beer and other products are all made by alcohol fermentation; the principle is: the protein in the fermented mash is hydrolyzed by protease to produce small molecules of peptone, peptides and various amino acids. Part of these hydrolysis products are absorbed by yeast to synthesize bacteria, and the other part is fermented to produce alcohol and carbon dioxide. The above fermentation is often completed in a fermentation tank.

[0003] For example, a Chinese utility model patent discloses an alcohol fermentation device (publication (announcement) number CN213388634U), which includes a fermentation tank, a vacuum pump, a gas-liquid separator, an alcohol collecting tank, a condenser, a scraper evaporator and a buffer tank. The lower middle part of the fermentation tank is connected to the liquid inlet of the scraper evaporator through a pipeline, the bottom of the scraper evaporator is connected to the top inlet of the buffer tank, the bottom outlet of the buffer tank is connected to the top inlet of the fermentation tank through a centrifugal pump, the top of the scraper evaporator is connected to the gas-liquid separator through the condenser, the top of the gas-liquid separator is connected to the vacuum pump, and the bottom is provided with an alcohol collecting tank; the alcohol fermentation device has a simple structure, low energy consumption, and can continuously feed, continuously collect alcohol, and continuously discharge, so as to keep the alcohol concentration of the fermented mash at a low level and reduce the yeast stress of the alcohol molecules.

[0004] However, when the inventors implemented this device, they found the following defects: the alcohol production in the fermentation tank is directly related to the fermentation of the fermented mash, especially in the initial stage of yeast inoculation, the yeast and the fermented mash are mixed with each other by a stirring mechanism fixed in the fermentation tank, and the mixing uniformity of the yeast and the fermented mash needs to be further improved.

[0026] Specifically, it also includes an auxiliary osmotic pushing assembly installed at the bottom of the cover body 1, the central axis of the auxiliary osmotic pushing assembly coincides with the central axis of the hollow shaft 5, the auxiliary osmotic pushing assembly includes an annular mesh cover 9 and at least three mounting columns 10, the top of the mounting column 10 is fixedly connected to the cover body 1, the annular mesh cover 9 is fixedly installed at the bottom of the mounting column 10, and the stirring paddle 6 is located in the annular mesh cover 9; during the movement of the stirring paddle 6 in the circulation guide trough 3, the annular mesh cover 9 moves synchronously with the stirring paddle 6, and the annular mesh cover 9 has a better pushing effect on the fermented mash in the circulation guide trough 3, and at the same time allows part of the fermented mash to enter the annular mesh cover 9 through the holes on the annular mesh cover 9, avoiding the fermented mash from being concentrated in contact with the stirring paddle 6, reducing the rotation resistance of the stirring paddle 6, ensuring the smooth rotation of the stirring paddle 6, promoting the circulation of the fermented mash in the tank body, and further improving the contact uniformity between the yeast and the fermented mash.

[0027] Specifically, the hollow shaft 5 is provided with a plurality of liquid outlet pipes 11 connected to the inside of the hollow shaft 5 near the stirring paddle 6; the liquid outlet pipes 11 are evenly distributed around the central axis of the hollow shaft 5; through the liquid outlet pipes 11, the solution containing yeast is more evenly dispersed into the tank body.

[0028] Specifically, a push-discharge assembly is provided at the bottom of the tank body, and the push-discharge assembly includes a discharge pipe 12 connected to the bottom of the tank body, a core rod 13 slidably installed in the discharge pipe 12, and a driving member that provides power for the core rod 13 to move up and down.

The driving member includes a threaded rod 15 rotatably installed at the bottom of the discharge pipe 12, a bevel gear transmission assembly 16 and a driving shaft 17. The driving shaft 17 is connected to the threaded rod 15 through the bevel gear transmission assembly 16. The bottom of the core rod 13 is screwed into the threaded rod 15. A valve plug 14 that fits the inner diameter of the discharge pipe 12 is provided on the outer wall of the discharge pipe 12. By rotating the drive shaft 17, the threaded rod 15 is rotated after being transmitted by the bevel gear transmission assembly 16, and after the threaded transmission, the core rod 13 can be driven to move up and down, so that the valve plug 14 is separated from the contact with the discharge pipe 12 or the discharge pipe 12 is blocked. When the fermented mash in the tank needs to be discharged outward, the valve plug 14 is separated from the blockage of the discharge pipe 12, and the fermented mash in the tank is discharged outward through the discharge pipe 12 and the discharge pipe 18. In the process of discharging the fermented mash, the drive shaft 17 is reciprocated to make the valve plug 14 push the fermented mash at the bottom of the tank up and down to prevent the fermented mash from concentrating at the discharge pipe 12 and completely blocking the discharge pipe 12.

[0029] Specifically, a liquid suction pipe 19 extending into the bottom of the tank body is installed on the cover body 1, and a liquid storage tank 20 is installed on the tank body, and the output end of the liquid suction pipe 19 extends into the liquid storage tank 20; the liquid storage tank 20 is vacuumed by an external vacuum pump, and the liquid produced by fermentation in the tank body enters the liquid storage tank 20 through the liquid suction pipe 19, so that the alcohol mixture produced by the fermentation is discharged separately, which is convenient for the subsequent extraction of alcohol; at the same time, a negative pressure and hypoxia effect can be generated in the tank body to further improve the fermentation effect of the fermented mash.

[0030] Specifically, the tank body is divided into an inner tank 21 and an outer tank 22, a hollow interlayer is formed between the inner tank 21 and the outer tank 22, and a heating component 23 is installed in the hollow interlayer; further, the heating component 23 is preferably an electric heater, such as an electric heating rod, an electric heating tube, etc.; the hollow interlayer can be heated by the electric heating component, thereby increasing the temperature in the inner tank 21, so as to increase the activity of yeast in the inner tank 21 and improve the fermentation effect of the fermented mash.

[0031] Specifically, it also includes a pressure gauge 24 extending into the inner tank 21 and a temperature gauge 25 extending into the hollow interlayer; the pressure in the inner tank 21 can be monitored in real time by the pressure gauge 24, and the temperature in the hollow interlayer can be monitored in real time by the temperature gauge 25.

[0032] When in use, the fermented mash is placed in the tank body, and the solution containing yeast is injected into the tank body through the hollow shaft 5 by an external pressure pump, etc. During this process, the output end of the driving cylinder 4 is frequently shortened and extended, so that the mounting frame 2 rotates back and forth around the hinge point, so that the stirring paddle 6 slides back and forth up and down along the circulating material guide trough 3. During this process, the driver 7 drives the hollow shaft 5 to rotate, thereby driving the stirring paddle 6 to rotate. During the rotation process, the stirring paddle 6 promotes the contact between the solution containing yeast and the fermented mash in the tank body, and during the sliding process along the circulating material guide trough 3, the stirring paddle 6 pushes the fermented mash at the bottom of the tank body along the circulating material guide trough 3 to the upper part of the tank body.
