Description

Technical Field

[0001] The invention relates to the technical field of fermented beverage production, in particular to a fermented beverage and a production device thereof. Background Art

[0002] The history of fermented beverages can be traced back to ancient times. As early as thousands of years ago, humans have begun to use natural fermentation methods to make various beverages, such as wine, beer, yogurt, etc. These traditional fermented beverages play an important role in different regions and cultures. They are not only part of people's daily diet, but also have certain medicinal value.

[0003] With the advancement of science and technology and the development of industrialized production, the types and production processes of fermented beverages have been continuously enriched and improved. Modern fermented beverages include not only traditional alcoholic beverages, yogurt, etc., but also a variety of new beverages such as fruit vinegar, enzyme beverages, fermented tea, etc. These fermented beverages are widely welcomed by consumers for their unique taste, rich nutrients and health benefits.

[0004] In the prior art, when fermented beverages are produced, a large number of bubbles will be generated in the liquid during fermentation, and the presence of bubbles will affect the fermentation efficiency of the fermented beverages. At the same time, when the temperature and air pressure inside the fermentation tank increase during the fermentation process, the stirring device that continues to stir at a high speed will not only not benefit the fermentation effect, but will even reduce the fermentation effect. Therefore, without solving the above problems, we provide a fermented beverage and a production device thereof. Summary of the invention

[0005] The problem to be solved by the present invention is how to enable the equipment to automatically eliminate the bubbles generated inside the fermentation raw materials when they are stirred and fermented, and when the internal temperature rises and the air pressure increases, the equipment automatically discharges the excess gas and reduces the stirring speed, thereby improving the efficiency of eliminating bubbles and avoiding the technical problem of reducing the fermentation effect. A fermented beverage and a production device thereof are provided.

[0008] When the user wants to produce a fermented beverage, the user can put the fermentation raw materials into the fermentation stirring device. After the fermentation stirring device is started, the fermentation raw materials can be stirred, mixed and fermented. The defoaming device can, driven by the fermentation stirring device, break and eliminate the bubbles generated inside the fermentation stirring device to avoid the generation of a large number of bubbles, thereby affecting the fermentation efficiency and the quality of the finished product. The pressure relief device can discharge the excess gas inside the fermentation stirring device when the temperature inside the fermentation stirring device rises and the air pressure increases, and control the fermentation stirring device to reduce its stirring speed, thereby avoiding the generation of too many bubbles and avoiding affecting the fermentation of the fermentation raw materials. The reduced stirring speed of the fermentation stirring device can drive the defoaming device to more efficiently eliminate the bubbles generated inside the fermentation stirring device.

[0009] This working method achieves the following: when the fermentation raw materials are stirred and fermented, the equipment can automatically eliminate the bubbles generated inside the equipment, and when the internal temperature rises and the air pressure increases, the equipment automatically discharges the excess gas and reduces the stirring speed, thereby improving the efficiency of eliminating bubbles and avoiding reducing the fermentation effect.

By arranging the pressure relief pipe, the return spring, the vertical push rod, the exhaust port and the rubber block, when the temperature inside the fermentation tank rises and the air pressure increases, the gas inside the fermentation tank can leave the fermentation tank through the pressure relief pipe and the exhaust port, thereby reducing the air pressure inside the fermentation tank, ensuring the safety of the fermentation tank and reducing the temperature inside the fermentation tank.

[0059] 3. By setting a fixed outer ring, a funnel-shaped ring piece, a transverse push rod, a bevel block, several outer ring fixed rods, and a push port, when the temperature and air pressure inside the fermenter increase, the transverse push rod can exert pressure on the funnel-shaped ring piece, thereby making the funnel-shaped ring piece close to the side of the stirring rod, increasing the load of the stirring rod, thereby reducing the rotation speed of the stirring motor, ensuring that when the temperature inside the fermenter increases, several stirring rods can be in a low-speed rotation state, reducing mechanical damage to microorganisms and stabilizing the fermentation system inside the fermenter. At the same time, it can also make several defoaming tubes rotate at a low speed, so that the contact time between several defoaming tubes and bubbles inside the fermenter is increased, thereby more effectively eliminating stubborn bubbles and improving defoaming efficiency.

One end of the lateral push rod 308 passes through the propulsion port and extends to the inside of the fixed outer ring 306, and contacts the outer side surface of the funnel-shaped ring piece 307. The other end of the lateral push rod 308 is set as an arc surface and is above the inclined block 309.

[0096] By setting the fixed outer ring 306, the funnel-shaped ring piece 307, the transverse push rod 308, the inclined block 309, the plurality of outer ring fixed rods 310, and the push port, when the temperature and air pressure inside the fermentation tank 201 increase, the transverse push rod 308 can apply pressure to the funnel-shaped ring piece 307, thereby making the funnel-shaped ring piece 307 close to the side of the stirring rod 203, increasing the load of the stirring rod 203, thereby reducing the rotation speed of the stirring motor 202, ensuring that when the temperature inside the fermentation tank 201 increases, the plurality of stirring rods 204 can be in a low-speed rotation state, reducing mechanical damage to microorganisms and stabilizing the fermentation system inside the fermentation tank 201. At the same time, the plurality of defoaming tubes 405 can be in a low-speed rotation state, so that the contact time between the defoaming device and the bubbles inside the fermentation tank 201 increases, thereby more effectively eliminating stubborn bubbles and improving defoaming efficiency.

[0097] The inner side surface of the funnel-shaped ring piece 307 is provided with a plurality of protrusions, and the protrusion surfaces of the plurality of protrusions are smooth.

[0098] The inner side surface of the funnel-shaped ring piece 307 is provided with a plurality of protrusions, which can effectively allow the stirring rod 203 to feel the increase of the load. At the same time, the smooth protrusion surfaces of the plurality of protrusions can avoid damage to the outer side surface of the stirring rod 203 to a certain extent.

[0099] The defoaming device comprises: a strip groove 401 , a connecting sleeve 402 , a sliding block, a plurality of floating plates 403 , a plurality of filter cartridges 404 , a plurality of through holes, and a plurality of defoaming tubes 405 .

[0100] The strip groove 401 is vertically arranged inside the fermentation tank 201 , and is arranged on one end of the stirring rod 203 inside the fermentation tank 201 , and is above the plurality of stirring rods 204 .

[0101] The sliding block is disposed inside the strip groove 401 and is slidably connected to the inner wall of the strip groove 401 .

[0102] The connecting sleeve 402 is arranged inside the fermentation tank 201, and is sleeved on the outer side of the stirring rod 203 inside the fermentation tank 201, on the outer side of the sliding block and above the plurality of stirring rods 204, and the inner side surface of the connecting sleeve 402 is fixedly connected to the side surface of the sliding block.

[0103] One end of a plurality of defoaming tubes 405 is closed, and they are laterally arranged inside the fermentation tank 201, above the plurality of stirring rods 204 and outside the connecting sleeve 402. The closed ends of the plurality of defoaming tubes 405 are fixedly connected to the outer side surface of the connecting sleeve 402 and are evenly distributed on the outer side of the connecting sleeve 402.

[0104] A plurality of floating plates 403 are laterally arranged inside the fermentation tank 201, above the plurality of stirring rods 204 and outside the connecting sleeve 402. The plurality of floating plates 403 are fixedly connected to the outer side of the connecting sleeve 402, and are respectively located between the defoaming tubes 405 that are close to each other in pairs, and are evenly distributed on the outer side of the connecting sleeve 402.

[0105] The plurality of through holes are respectively arranged on the side portions of the plurality of defoaming tubes 405 close to the plurality of stirring rods 204 , and the plurality of through holes are respectively communicated with the interiors of the plurality of defoaming tubes 405 .

[0106] The lengths of the filter cartridges 404 match those of the defoaming tubes 405 , and the filter cartridges 404 are respectively disposed inside the defoaming tubes 405 and fixedly connected to the inner walls of the defoaming tubes 405 .

[0107] The arrangement of the plurality of floating plates 403 can ensure that the connecting sleeve 402 and the plurality of defoaming tubes 405 can be in a position flush with the liquid surface inside the fermentation tank 201. The plurality of through holes are arranged on the sides of the plurality of defoaming tubes 405, and the plurality of filter cartridges 404 are arranged inside so that the user can put a defoaming agent in the filter cartridge 404 before installing the filter cartridge 404, so that after the defoaming agent contacts the liquid inside the fermentation tank 201, it can better react with the bubbles through the plurality of through holes, thereby improving the defoaming efficiency.

[0108] A plurality of spikes are respectively arranged on the outer sides of the plurality of defoaming tubes 405 , and the plurality of spikes are evenly distributed and avoid the positions where the plurality of through holes are located.

[0109] A plurality of spikes are respectively arranged on the outer sides of the plurality of defoaming tubes 405 to further improve the defoaming efficiency of the plurality of defoaming tubes 405 .

[0110] The filter screen diameters of the filter cartridges 404 are smaller than the diameter of the fermentation raw materials inside the fermentation tank 201 .

[0111] The filter screen diameters of the filter cartridges 404 are set to be smaller than the diameter of the fermentation raw materials inside the fermentation tank 201 to prevent the liquid inside the fermentation tank 201 and the fermentation raw materials adhering to the bubbles from directly entering the defoaming tubes 405 through the through holes.

[0112] A fermented beverage, which is fruit wine.

[0113] Working process: When the user puts all the fermentation raw materials into the fermentation tank 201 through the feed pipe 208, and then installs the sealing cover of the feed port, the floating plates 403 will float up, and the floating plates 403 will drive the connecting sleeve 402 to move upward, and the connecting sleeve 402 will move upward to drive the sliding block to move upward, and drive the defoaming tubes 405 to move upward, and the defoaming tubes 405 will move upward to drive the filter cartridges 404 to move upward, until the floating plates 403 float to the position where the liquid surface is located. Then the user can start the stirring motor 202 through the controller. When the stirring motor 202 is started, the stirring motor 202 drives the stirring rod 203 to rotate, and the stirring rod 203 rotates to drive the stirring rod 204 to rotate, and drives the sliding block to rotate. The rotation of the stirring rod 204 can stir the fermentation raw materials inside the fermentation tank 201, thereby improving the mixing effect, promoting the production of microorganisms, and improving the fermentation effect.

[0114] When the sliding block rotates, the sliding block rotates and the connecting sleeve 402 rotates, and the connecting sleeve 402 rotates and the floating plates 403 and the defoaming tubes 405 rotate, and the defoaming tubes 405 rotate and the spikes on the surface and the filter cartridges 404 rotate. The spikes on the defoaming tubes 405 can eliminate the bubbles on the liquid surface, and the presence of the through holes can better adsorb and eliminate the bubbles. Before the filter cartridges 404 are installed into the defoaming tubes 405, the user can first place the defoaming agent into the filter cartridges 404, so that the defoaming agent evaporates into the liquid through the holes of the filter cartridges 404 and the through holes of the defoaming tubes 405, and the cooperation between the filter cartridges 404 and the through holes can also prevent impurities in the bubbles or liquid from entering the defoaming tubes 405.

[0115] When the fermentation raw materials inside the fermentation tank 201 are continuously fermented, the air pressure inside the fermentation tank 201 will gradually increase. At the same time, the increase in temperature inside the fermentation tank 201 will also cause the air pressure to increase. When the air pressure inside the fermentation tube increases to a certain level, the gas inside the fermentation tank 201 will enter the pressure relief pipe 301 through the bottom end of the pressure relief pipe 301, and the gas pushes the rubber block 305 to move upward. The upward movement of the rubber block 305 pushes the vertical push rod 303 to move upward, and applies pressure to the return spring 302, so that the return spring 302 is shortened until the rubber block 305 moves above the exhaust port 304. When the rubber block 305 is above the exhaust port 304 of the pressure relief pipe 301, the gas inside the pressure relief pipe 301 will enter the exhaust gas treatment pool through the exhaust port 304 and the pipeline. By discharging the gas directly into the waste gas treatment pool, it is possible to prevent the outside air from entering the pressure relief pipe 301 through the exhaust port 304 and then entering the fermentation tank 201, thereby affecting the fermentation effect.

[0116] When the air pressure inside the fermentation tank 201 reaches the same air pressure as that outside, the gas will stop pushing the rubber block 305 upward, and the return spring 302 will stop being pressurized by the rubber block 305. The return spring 302 will rebound and extend after stopping being pressurized. The extension of the return spring 302 drives the rubber block 305 to move downward. The downward movement of the rubber block 305 drives the vertical push rod 303 to move downward until the rubber block 305 moves to the initial position.

[0117] When the vertical push rod 303 moves upward, the vertical push rod 303 drives the inclined plane block 309 to move upward. When the inclined plane block 309 moves upward, the highest point of the inclined plane of the inclined plane block 309 will contact the arc surface of the horizontal push rod 308, and apply an extrusion thrust to the arc surface of the horizontal push rod 308 until the inclined plane block 309 moves upward to the lowest point of the inclined plane of the inclined plane block 309 and contacts the arc surface of the horizontal push rod 308. When the arc surface of the lateral push rod 308 is subjected to the extrusion thrust of the inclined block 309, the inclined surface of the lateral push rod 308 moves toward the direction close to the funnel-shaped ring piece 307 and applies pressure to the side of the funnel-shaped ring piece 307. The funnel-shaped ring piece 307 made of spring steel itself has the elasticity and contractility of a spring. Therefore, when the side of the funnel-shaped ring piece 307 is subjected to pressure, the inner side surface of the bottom end of the funnel-shaped ring piece 307 will move as a whole toward the side close to the stirring rod 203 until it contacts the side of the stirring rod 203 and applies pressure to the side of the stirring rod 203. At this time, the stirring rod 203 will increase the load after being subjected to pressure. After the stirring motor 202 senses the increase in the load of the stirring rod 203, it will actively control the speed to decrease, thereby avoiding damage to the stirring motor 202. The reduced speed of the stirring motor 202 drives the reduced speed of the stirring rod 203, the reduced speed of the stirring rod 203 drives the reduced speed of the sliding block and the plurality of stirring rods 204, the reduced speed of the sliding block drives the reduced speed of the connecting sleeve 402, the reduced speed of the connecting sleeve 402 drives the reduced speed of the plurality of defoaming tubes 405, the reduced speed of the plurality of defoaming tubes 405 drives the plurality of spikes on the surface thereof, and the plurality of filter cartridges 404 to reduce the speed. The reduction of the plurality of defoaming tubes 405 can increase the time that the plurality of through holes and the plurality of spikes on the plurality of defoaming tubes 405 are in contact with the bubbles, thereby improving the efficiency of defoaming. The reduced speed of the plurality of stirring rods 204 can reduce the generation of bubbles inside the fermentation tank 201, and at the same time avoid high-speed stirring of the fermentation raw materials in a high-pressure and high-temperature environment, thereby reducing the mechanical damage to the microorganisms and stabilizing the fermentation system.

[0118] When the vertical push rod 303 moves downward, the vertical push rod 303 drives the inclined surface block 309 to move downward. When the inclined surface block 309 moves downward, the inclined surface of the inclined surface block 309 stops applying an extrusion thrust to the arc surface of the lateral push rod 308 until the inclined surface of the inclined surface block 309 leaves the arc surface of the lateral push rod 308 and returns to its original position. When the lateral push rod 308 stops being subjected to the extrusion thrust of the arc surface, the inclined surface of the lateral push rod 308 stops applying pressure to the funnel-shaped ring piece 307, and the funnel-shaped ring piece 307 is After the sheet 307 stops being subjected to pressure, the funnel-shaped ring sheet 307 as a whole will gradually recover and push the lateral push rod 308 to move toward the direction close to the inclined block 309. At the same time, the inner side surface of the funnel-shaped ring sheet 307 will gradually move away from the outer side surface of the stirring rod 203 and stop applying load pressure to the stirring rod 203. When the stirring rod 203 stops being subjected to load pressure, the stirring motor 202 will gradually restore its rotation speed until the funnel-shaped ring sheet 307 is completely restored and the stirring motor 202 returns to its initial speed.

[0119] When the production of the fermented beverage inside the fermentation tank 201 is completed, the user can stop the stirring motor 202 through the controller and start the discharge valve 207. After the discharge valve 207 is started, the fermented beverage inside the fermentation tank 201 will flow out of the fermentation tank 201 through the discharge valve 207, thereby completing the production of the fermented beverage and collecting the fermented beverage.

Based on the embodiments of the present invention, other embodiments obtained by those skilled in the art without creative work shall all fall within the scope of protection of the present invention.
