Description

Technical Field

[0001] The invention relates to the technical field of lactic acid bacteria fermentation, in particular to yogurt lactic acid bacteria fermentation equipment. Background Art

[0002] Lactic acid bacteria refers to a class of non-spore, Gram-positive bacteria whose main product of fermentation of sugars is lactic acid. Lactic acid bacteria can be said to be the "stimulant" of human immune cells such as macrophages and NK cells. Lactic acid bacteria can activate these cells to eliminate harmful bacteria and cancer cells in the body; Before fermentation, yogurt needs to be stirred with fermentation drugs to make them fully mixed. At the same time, oxygen needs to be provided to the yogurt during stirring so that the fermented product can multiply certain probiotics when the yogurt is mixed. Since traditional devices basically inject gas into the stirring chamber when mixing yogurt with materials to make the fermented product contact with oxygen, and since oxygen is basically retained on the surface of the yogurt when oxygen is injected into the yogurt, the fermented product can only contact with oxygen by flowing during stirring, which makes it difficult for oxygen to enter the interior of the yogurt for sufficient contact, thereby affecting the growth period in the early stage of fermentation, reducing the fermentation efficiency of yogurt and affecting the reproduction rate of lactic acid bacteria.

[0012] The present invention has the following beneficial effects: 1. In the present invention, when the motor drives the rotating roller to rotate, the rotating roller will drive the hollow cylinder to rotate inside the inflation tube. When the rotating roller drives the hollow cylinder to rotate, the rotation of the hollow cylinder will drive the hollow plate 2 to rotate synchronously through the hollow tube. Then, when the gas inside the oxygen pump is being transported, the oxygen will enter the inflation tube and enter the hollow tube through the air inlet hole on the hollow cylinder. Then, the gas will enter the hollow plate 2 through the small hole on the hollow tube. At the same time, when the hollow cylinder rotates, the rotation of the hollow cylinder will also drive the insertion rod on the hollow plate 1 to slide up and down through the inclined groove inside the hollow cylinder. When the rotation of the hollow cylinder drives the insertion rod to slide, the sliding of the insertion rod will slide in the right-angle groove on the rotating shaft and drive the rotating shaft to rotate in the opposite direction of the hollow cylinder. Then, When the rotating shaft rotates, the rotation of the rotating shaft will drive the fan tube and the grille ring to rotate in the opposite direction to the hollow tube inside the hollow plate 2. After that, when the hollow tube rotates, the rotation of the hollow tube will drive several hoses to rotate synchronously through the hollow tube and the hollow plate 2. Subsequently, when the grille ring rotates in the opposite direction to the hollow tube, the rotation of the grille ring and the gas transported to the inside of the inflation tube by the oxygen pump continuously enter the hose through the hollow plate 2 and are ejected outward through the air jet holes on the hose. By jetting the gas into the yogurt when stirring, the gas can be supplied over a large area in the yogurt and surge upward, reducing the problem of oxygen being difficult to enter the inside of the yogurt under traditional stirring methods, effectively increasing the contact area between yogurt and oxygen, and increasing the reproduction rate of lactic acid bacteria, thereby shortening the growth delay period in the early stage of fermentation.

[0013] 2. According to the present invention, when the rotation of the hollow tube drives the hollow plate 2 to rotate, the rotation of the hollow plate 2 will drive multiple spring frames to rotate synchronously. When the spring frame rotates, the rotation of the spring frame will drive the rotating cylinder to rotate synchronously. When the rotating cylinder rotates, it will rotate on the surface of the inflation tube and slide up and down along the trajectory of the Z-shaped groove inside the Z-shaped groove on the inflation tube while rotating. When the rotating cylinder rotates, the rotation of the rotating cylinder will drive multiple rotating plates 1 to rotate synchronously through the fixed block. At the same time, when the rotating plate 1 rotates, the rotation of the rotating plate 1 will drive the shaking ring to rotate synchronously. Subsequently, when the rotating cylinder drives the rotating plate 1 to rotate, the rotation of the rotating plate 1 will be squeezed by the spring block to rotate inside the fixed block. When the shaking ring rotates, it will drive the shaking ring to deflect. When the shaking ring deflects, it will push the hose. After being pushed, the hose will expand the jet range of the jet inside the yogurt, so that the gas can be supplied over a large area and evenly distributed in the yogurt, so that the lactic acid bacteria in the yogurt can grow and ferment in a more suitable gas environment, thereby improving the fermentation efficiency.

[0014] 3. According to the present invention, when the device stirs the yogurt inside and the shaking ring is deflected, the shaking of the shaking ring and the flow of water during stirring can drive the elastic plate to shake up and down through the spring, and when the elastic plate shakes, it will drive the top and bottom telescopic rings to shake up and down, and when the telescopic ring shakes up and down, it will drive the fixed rod to shake through the sliding ring, and when the fixed rod shakes, it will drive the bottom circular ring to slide up and down inside the hollow plate 2 and intermittently block the circular hole of the hose in the hollow plate 2, so that the hose can intermittently spray gas during stirring, thereby avoiding excessive gas supply inside the yogurt, reducing the excessive oxidation of the yogurt and the generation of bad odor due to excessive supply, thereby improving the fermentation quality of the yogurt.

[0015] 4. In the present invention, when the plurality of elastic plates and the hollow ring rotate, the rotation of the hollow ring will drive the second rotating plate to rotate synchronously. At the same time, when the elastic plate drives the telescopic ring to shake, the telescopic ring on the top of the plurality of elastic plates will drive the second rotating plate to rotate reciprocatingly on the hollow ring through the spring rod when shaking. When the second rotating plate rotates on the hollow ring, the angle of the through-hole shaft will be adjusted. Subsequently, when the second rotating plate rotates synchronously with the rotation of the hollow ring, the rotation of the hollow ring will drive the second rotating plate and the through-hole shaft to rotate synchronously. When the through-hole shaft rotates, the yogurt inside the main body will be inside the through-hole shaft. When the yogurt flows rapidly through the through-hole shaft, the flexible belt on the through-hole shaft will shake in a wave-like manner under the resistance of the yogurt flow, and then the flexible belt will hit the bubbles generated by the gas ejected from the hose when shaking, and disperse the large bubbles into small bubbles. Since the small bubbles rise slower than the large bubbles in the yogurt, this can make the oxygen stay in the yogurt longer, further creating a more favorable growth environment for the fermentation of the yogurt. At the same time, the slowly rising small bubbles also reduce the disturbance to the yogurt, which helps to maintain the stability of the yogurt re-fermentation process.

[0016] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

When the motor 104 is working, it will drive the rotating roller 301 to rotate, and when the rotating roller 301 rotates, it will drive the fan tube 305 to stir the yogurt inside the main body 1.

[0030] When the motor 104 drives the rotating roller 301 to rotate, the rotating roller 301 drives the hollow cylinder 302 to rotate inside the inflatable tube 201. When the rotating roller 301 drives the hollow cylinder 302 to rotate, the rotation of the hollow cylinder 302 drives the hollow plate 2 402 to rotate synchronously through the hollow tube 303. Then, when the gas inside the oxygen pump is being transported, the oxygen enters the inflatable tube 201 and enters the air through the air inlet hole on the hollow cylinder 302. The gas will then enter the hollow plate 402 through the small hole on the hollow tube 303. At the same time, when the hollow tube 302 rotates, the rotation of the hollow tube 302 will also drive the insertion rod on the hollow plate 401 to slide up and down through the inclined groove inside the hollow tube 302. When the rotation of the hollow tube 302 drives the insertion rod to slide, the sliding of the insertion rod will slide in the right-angle groove on the rotating shaft 304 and drive the rotating shaft 304 to rotate in the opposite direction of the hollow tube 302.

By jetting the gas into the yogurt when stirring, the gas can be supplied to a large area in the yogurt and surge upward, reducing the problem that oxygen is difficult to enter the inside of the yogurt under the traditional stirring method, effectively increasing the contact area between the yogurt and the oxygen, and improving the reproduction rate of lactic acid bacteria, thereby shortening the growth delay period in the early stage of fermentation.

[0031] When the rotation of the hollow tube 303 drives the hollow plate 2 402 to rotate, the rotation of the hollow plate 2 402 will drive the multiple spring frames 501 to rotate synchronously. When the spring frame 501 rotates, the rotation of the spring frame 501 will drive the rotating cylinder 502 to rotate synchronously. When the rotating cylinder 502 rotates, it will rotate on the surface of the inflatable tube 201 and at the same time, the round rod on the inner wall of the rotating cylinder 502 will slide up and down along the track of the Z-shaped groove 202 inside the Z-shaped groove 202 on the inflatable tube 201. When the rotating cylinder 502 is rotating, the rotation of the rotating cylinder 502 will drive the multiple rotating plates 1 701 to rotate synchronously through the fixed block 503. At the same time, the rotating plate 1 When 701 rotates, the rotation of rotating plate 701 will drive the shaking ring 702 to rotate synchronously. Then, when the rotating cylinder 502 drives the rotating plate 701 to rotate, the rotation of the rotating plate 701 will be squeezed by the spring block 204 and rotate inside the fixed block 503. When the shaking ring 702 rotates, it will drive the shaking ring 702 to deflect. When the shaking ring 702 deflects, it will push the hose 404. After being pushed, the hose 404 will expand the jet range of the jet inside the yogurt, so that the gas can be supplied over a large area and evenly distributed in the yogurt, so that the lactic acid bacteria in the yogurt can grow and ferment in a more suitable gas environment, thereby improving the fermentation efficiency.

[0032] When the device stirs the yogurt inside and the shaking ring 702 is deflected, the shaking of the shaking ring 702 and the flow of water during stirring can drive the elastic plate 504 to shake up and down through the spring 703. When the elastic plate 504 shakes, it will drive the top and bottom telescopic rings 601 to shake up and down. When the telescopic ring 601 shakes up and down, it will drive the fixed rod 603 to shake through the sliding ring 602. When the fixed rod 603 shakes, it will drive the bottom circular ring to slide up and down inside the hollow plate 402 and intermittently block the circular hole of the hose 404 in the hollow plate 402, so that the hose 404 intermittently sprays air during stirring, avoiding excessive supply of gas inside the yogurt, reducing excessive oxidation and bad odor of the yogurt caused by excessive supply, and thus improving the fermentation quality of the yogurt.

[0033] When the multiple elastic plates 504 and the hollow ring 405 rotate, the rotation of the hollow ring 405 will drive the rotating plate 2 802 to rotate synchronously. At the same time, when the elastic plate 504 drives the telescopic ring 601 to shake, the telescopic ring 601 on the top of the multiple elastic plates 504 will drive the rotating plate 2 802 to rotate reciprocatingly on the hollow ring 405 through the spring rod 801 when shaking. When the rotating plate 2 802 rotates on the hollow ring 405, the angle of the through-hole shaft 803 is adjusted. Subsequently, when the rotating plate 2 802 rotates synchronously with the rotation of the hollow ring 405, the rotation of the hollow ring 405 will drive the rotating plate 2 802 and the through-hole shaft 803 to rotate synchronously. When the through-hole shaft 803 rotates When the yogurt moves, the yogurt inside the main body 1 will flow rapidly inside the through-hole shaft 803. When the yogurt flows rapidly through the through-hole shaft 803, the flexible belt 804 on the through-hole shaft 803 will shake in a wave-like manner under the resistance of the yogurt flow. Then, when the flexible belt 804 shakes, it will hit the bubbles generated by the gas ejected from the hose 404, and disperse the large bubbles into small bubbles. Since the small bubbles rise slower in the yogurt than the large bubbles, this can make the oxygen stay in the yogurt longer, further creating a more favorable growth environment for the fermentation of the yogurt. At the same time, the slowly rising small bubbles also reduce the disturbance to the yogurt, which helps to maintain the stability of the yogurt fermentation process.
