Description

Technical Field

[0001] The utility model relates to the technical field of yogurt production equipment, in particular to a sterilization and fermentation device for yogurt production. Background Art

[0002] Yogurt has won wide popularity with its unique flavor, comprehensive nutritional value and digestive health benefits. The secret of its production lies in the ingenious combination of fresh milk and selected lactic acid bacteria fermentation agents. After the transformation process of biological fermentation, it not only gives milk a new taste experience, but also improves human health. For this reason, in the modern yogurt manufacturing industry, the application of sterilization and fermentation technology has become more and more extensive, playing a role that cannot be underestimated. This technology is directly related to the delicate taste, rich texture and ability to extend the shelf life of yogurt, and is also a key link to ensure that the product meets high standards of quality and safety.

[0003] For example, Chinese patent CN213881602U discloses a sterilization device for yogurt production, including a sterilizing pot, a sealing cover, a scraper, a push-pull rod, and a rubber scraper. By pulling the push-pull rod, the yogurt attached to the inside of the sterilizing device can be cleaned, so that the discharge is clean and complete, reducing losses, and then through the cooperation of the pull block, the pull groove, the locking block and the spring, the push-pull rod can be quickly disassembled to avoid collision with the internal stirring mechanism, and the disassembly and installation are convenient. However, when the above-mentioned sterilization device cleans the yogurt attached to the inside of the sterilization device by pulling the push-pull rod, it is configured with a scraper that matches the inner diameter of the sterilizing pot, so that the rubber scraper can be close to the inner wall of the device, and then the yogurt attached to the inner wall is scraped off, which makes it necessary to replace the scraper of the corresponding diameter when scraping the inner wall of the sterilizing pot with different diameters, which greatly causes the inconvenience of scraping the sterilizing pots with different diameters.

[0024] In addition, it should be noted that the above-mentioned sterilization barrel 1 includes a heating layer and a temperature control system. The heating layer can be an electric heating wire. The temperature control system includes a temperature sensor, a controller and an actuator, which are used to monitor and adjust the temperature in the barrel to ensure that the set sterilization temperature is reached and maintained. The pasteurization technology is used to ensure that the sterilization temperature is controlled at 60°C for about half an hour, thereby achieving the purpose of pasteurization. At the same time, the optimal temperature for yogurt fermentation is controlled at 40-42°C. This is a prior art and will not be elaborated on here.

[0025] In addition, it should be noted that the above-mentioned cylinder 3 is composed of a cylinder barrel, an end cover, a piston, a piston rod and a sealing ring. The working principle of the cylinder 3 is a process based on the conversion of gas pressure into mechanical energy. The composition and working principle of the cylinder 3 are existing technologies and will not be elaborated in detail here.

[0026] In addition, it should be noted that the above-mentioned discharge valve 5 is composed of a valve body, a valve seat, a valve plate, a driving mechanism and a sealing member. The working principle of the discharge valve 5 is to control the outflow of materials in the container or pipeline through a movable valve plate; when the material needs to flow out, the valve control mechanism drives the movable component to open, so that the material can be discharged from the outlet through the valve body; when the material does not need to flow out or needs to stop flowing out, the movable component will be driven back to the closed position, tightly fit with the valve seat, form a seal, and prevent the material from continuing to flow out.

At this time, the buckle on the lock tongue engages with the groove on the corresponding fixed component to achieve locking; the key is operated in reverse to reverse the mechanical structure inside the lock core, and the lock plate drives the lock tongue to return, releasing the engagement state with the buckle groove, so that the locked object can be pulled open or opened; the composition and working principle of the buckle lock body 6 and the buckle seat 8 are all prior art, which will not be elaborated here.

[0028] With the aid of the above-mentioned technical scheme of the utility model, the utility model is provided with a rotating scraping mechanism 10, so that the microorganisms used for fermentation are evenly mixed with the raw milk, and the temperature of each part in the sterilization and fermentation device is kept uniform. It is also convenient to scrape and clean the yogurt attached to the inner wall of the sterilization and fermentation device of different diameters, thereby greatly ensuring the quality of yogurt fermentation.

[0029] In one embodiment, for the above-mentioned rotary scraping mechanism 10, the rotary scraping mechanism 10 includes a rotary column 1001 connected to the output shaft of the motor 9, and the top and bottom outer sides of the rotary column 1001 are both provided with fixed rings 1002, and the outer side of the fixed ring 1002 is provided with a plurality of lifting ears 1003, and the lifting ears 1003 are connected to the connecting rod 1005, and the ends of the two sets of connecting rods 1005 away from the rotary column 1001 are connected to the rubber scraper 1006; a movable column 1007 is provided at the top of the cylinder 3, and the outer side of the movable column 1007 is provided with a plurality of lifting ears 1008, and the lifting ears 1008 are connected to the connecting rod 1009, and the connecting rod 1009 is away from the rotary column 1 One end of 001 is connected to the rubber scraper 1006; a plurality of stirring rods 1010 are arranged on the outside of the rotating column 1001 and between the two groups of fixing rings 1002 and the two groups of rubber scrapers 1006, and a plurality of stirring rods 1011 are arranged on the side of the rubber scraper 1006 close to the connecting rod 1005 and between the two groups of connecting rods 1005; under the rotation of the output shaft of the motor 9, the rotating column 1001 can be driven to rotate, thereby driving the rotation of the stirring rod 1010 and the stirring rod 1011, so that the microorganisms inside the sterilization barrel 1 can be fully contacted with the raw milk due to stirring, and the problem of low fermentation degree caused by local overheating that destroys the growth environment of the microorganisms is avoided.

[0030] In one embodiment, for the above-mentioned movable column 1007, the movable column 1007 is located at the bottom end of the rotating column 1001, and a bearing is arranged between the movable column 1007 and the driving shaft of the cylinder 3, the cross-section of the rubber scraper 1006 is a T-shaped structure, and the two sets of connecting rods 1005 and the rubber scraper 1006 and the rotating column 1001 form a parallelogram structure, and the extension line of the connecting rod 1 1005 located below intersects with the extension line of the connecting rod 2 1009; under the action of the extension of the piston rod of the cylinder 3, the movable column 1007 can be pushed to move upward, thereby driving the connecting rod 1005 and the connecting rod 2 1009 to make an arc movement, and then pushing the rubber scraper 1006 to move toward the inner wall of the sterilization barrel 1, and finally making the rubber scraper 1006 close to the inner wall of the sterilization barrel 1 for cleaning.

[0031] In addition, it should be noted that the above-mentioned bearing is composed of an inner ring, an outer ring, rolling elements and a retaining frame. The working principle of the above-mentioned bearing is based on the principle that rolling friction replaces sliding friction, thereby reducing friction and wear and improving mechanical efficiency. The composition and working principle of the bearing are existing technologies and will not be elaborated in detail here.

[0032] The working principle of the rotary scraping mechanism 10 is as follows: the piston rod of the cylinder 3 extends to drive the movable column 1007 to move upward, thereby driving the connecting rod 1009 to make an arc movement toward the inner wall of the sterilization barrel 1, and under the cooperation of the limiting function of the fixed ring 1002 and the connecting rod 1 1005 connected to the rubber scraper 1006, the rubber scraper 1006 is pushed to move toward the inner wall of the sterilization barrel 1, and finally the rubber scraper 1006 can be close to the inner wall of the sterilization barrel 1, and then the rotating column 1001 is driven to rotate by the rotation of the output shaft of the motor 9, so that the stirring rod 1 1010 outside the rotating column 1001 rotates, and under the limiting function of the fixed ring 1002 and the connection between the connecting rod 1 1005 and the connecting rod 2 1009. Under the action of the stirring rod 2 1011 on one side of the rubber scraper 1006, the stirring rod 2 1011 rotates, so that the microorganisms inside the sterilization barrel 1 can fully contact with the raw milk due to stirring, and the problem of low fermentation degree caused by local overheating that destroys the growth environment of the microorganisms is avoided. After all the yogurt flows out, the piston rod of the cylinder 3 retracts, so that the movable column 1007 moves downward, thereby driving the connecting rod 2 1009 to make an arc movement away from the inner wall of the sterilization barrel 1, and under the limiting action of the fixed ring 1002 and the cooperation of the connecting rod 1 1005 connected to the rubber scraper 1006, the rubber scraper 1006 is pulled to move in the direction away from the inner wall of the sterilization barrel 1, so that the rotating scraping mechanism 10 can be taken out of the sterilization barrel 1 for cleaning.

[0033] In order to facilitate understanding of the above technical solution of the present invention, the working principle or operation method of the present invention in the actual process is described in detail below.

[0034] In actual application, the staff adds raw milk into the sterilization barrel 1, and then locks the sealing cover 7 and the sterilization barrel 1 through the cooperation of the buckle lock body 6 and the buckle seat 8 to keep the sterilization barrel 1 sealed, and then controls the temperature at 60°C through the heating layer in the sterilization barrel 1, and keeps it for about half an hour to pasteurize the raw milk and the sterilization and fermentation device, and then stops heating, waits for the temperature in the sterilization and fermentation device to drop to 40-42°C, and opens the sealing cover 7 by unfastening the buckle lock body 6 and the buckle seat 8, pours the fermentation microorganisms into the sterilization barrel 1, and locks the sealing cover 7 and the sterilization barrel 1 again through the cooperation of the buckle lock body 6 and the buckle seat 8 to keep the sterilization barrel 1 sealed, and then controls the temperature at 60°C through the heating layer in the sterilization barrel 1 again. Fermentation is carried out at about 40-42°C and stirred by a rotary scraping mechanism 10 (the working principle of the rotary scraping mechanism 10 is as shown above). After the fermentation is completed, the fermented yogurt is discharged by opening the discharge valve 5. The continuous stirring of the rotary scraping mechanism 10 (the working principle of the rotary scraping mechanism 10 is as shown above) will scrape and clean the yogurt still attached to the inner wall of the sterilization barrel 1 to the bottom of the sterilization barrel 1, so that the residual amount of yogurt on the inner wall of the sterilization barrel 1 is as small as possible to reduce waste. Then, the rotary scraping mechanism 10 (the working principle of the rotary scraping mechanism 10 is as shown above) is used again, and the buckle lock body 6 and the buckle seat 8 are unlocked, and the sealing cover 7 is opened to thoroughly clean the sterilization and fermentation device to ensure that there is no pollution when it is used next time.

Rotation allows the microorganisms inside the sterilization barrel 1 to fully contact with the raw milk due to stirring, and also avoids the problem of low fermentation degree caused by local overheating that destroys the growth environment of the microorganisms; by setting up a rotating scraping mechanism 10, the movable column 1007 can be pushed upward under the action of the extended piston rod of the cylinder 3, thereby driving the connecting rod 1 1005 and the connecting rod 2 1009 to move in an arc, and then pushing the rubber scraper 1006 to move toward the inner wall of the sterilization barrel 1, and finally allowing the rubber scraper 1006 to close to the inner wall of the sterilization barrel 1 for cleaning.
