Description

Technical Field

[0001] The invention belongs to the technical field of yogurt seasoning powder preparation equipment, and in particular relates to a spraying device for preparing rose yogurt seasoning powder. Background Art

[0002] Yogurt seasoning powder is a powdered substance that can give yogurt a unique flavor to meet the preferences of different consumers, and rose yogurt seasoning powder is a yogurt seasoning powder featuring the unique aroma and flavor of roses, which can give yogurt a romantic and charming rose flavor and improve the taste of yogurt. Spray equipment is required in the preparation process of yogurt seasoning powder, mainly because spray drying technology can quickly atomize the prepared liquid material containing flavor substances into tiny droplets, and then under the action of hot air, the water evaporates quickly, and the material is quickly dried to form a powder, which can well retain the flavor components and ensure the quality of the seasoning powder. For example, the patent authorization announcement is CN112933625B, which discloses a spray equipment for preparing yogurt seasoning powder.

[0003] At present, when preparing rose yogurt seasoning powder, if the rose seasoning stock solution contains incompletely dissolved macromolecular polysaccharides, plant fibers and some tiny rose petal residues, these substances are easy to gradually accumulate and adhere when passing through the narrow channel of the atomizing nozzle because of their large particles or certain viscosity, and then the nozzle of the spraying equipment is easy to be blocked, which will cause the liquid material to be unable to be atomized and sprayed normally, affecting the drying process, and even causing production interruption, and may also cause some materials to stay for a long time and deteriorate, which not only affects the reliability and effect of the use of the spraying device, but also easily affects the quality of the preparation of rose yogurt seasoning powder; In addition, when the atomizing equipment nozzle atomizes the rose flavoring concentrate, small droplets formed by the atomization of part of the concentrate tend to accumulate on the outer wall of the nozzle, forming droplets of concentrate attached. At this time, these droplets are affected by the high temperature of the drying chamber of the powder drying equipment, which will evaporate the water in the droplets of concentrate attached, causing the flavoring substances in the droplets of concentrate attached to dry and adsorb on the outside of the nozzle. As the use time goes by, the increase in the amount of dried flavoring substances will interfere with the atomization effect of the nozzle, affect the uniformity of the dispersion of the small droplets of the rose flavoring concentrate, and cause the local atomized small droplets of the rose flavoring concentrate to be too large, thereby making the particles of some rose flavoring powder larger. This not only affects the preparation quality of the rose flavoring powder, but may also clog the nozzle and reduce the reliability of the atomizing equipment.

[0014] Compared with the prior art, the advantages of a spray device for preparing rose yogurt seasoning powder are: 1. Through the impurity separation mechanism, driving mechanism, pressurizing mechanism and spray head, when preparing rose yogurt seasoning powder, first, the PLC controller controls the liquid inlet control valve to open, and the rose seasoning stock solution enters the impurity separation mechanism from the pipeline, and the PLC controller also controls the driving mechanism to rotate the transmission rod. The rotation of the transmission rod makes the impurity separation mechanism generate centrifugal force, and the centrifugal force is used to accelerate the efficiency of impurity separation in the rose seasoning stock solution, avoid the situation that the spray channel of the spray head is blocked, and will not affect the drying process of the rose seasoning powder, nor will it cause production interruption, and will not cause part of the material to deteriorate due to long-term residence. After separation, the pure rose seasoning stock solution is then transported to the pressurizing mechanism for pressurization, and finally the high-pressure and pure rose seasoning stock solution is sprayed out through the spray head. The mechanism enables the spray equipment to have the function of separating impurities of the rose seasoning stock solution, so that the atomization equipment has the ability to prevent blocking in the process of preparing the rose seasoning powder, and improves the reliability and effect of the use of the atomization equipment, and can ensure the quality of the preparation of the rose yogurt seasoning powder.

[0015] 2. Through the micro water pump and anti-drying mechanism, the atomizing equipment fills the water tank and the filter area at the bottom of the partition with pure water through the one-way water inlet valve during operation. At the same time, the PLC controller not only controls the start of the micro water pump, but also controls the output end of the servo motor to rotate 180° every 4 hours. The micro water pump sucks pure water and transports it to the anti-drying mechanism, and sprays pure water mist in the atomization direction of the rose flavoring stock solution. The water mist will form a cooling zone in the spray hole, and try to avoid the large amount of heat inside the drying chamber of the powder drying equipment to be transferred to the outer end of the spray head, thereby preventing the spray head from causing the droplets attached to the stock solution to dry up due to high temperature. , accumulated on its side end surface, and at the same time, try to avoid the accumulation of dried flavoring substances on the surface of the spray head, and avoid the increase of flavoring substances to interfere with the atomization effect of the spray head, which can ensure the uniformity of small droplets of rose flavoring liquid after atomization, and at the same time avoid the local atomization of rose flavoring liquid droplets too large to produce large particles of poor quality rose flavoring powder. This mechanism enables the atomization equipment to have the function of cooling the surface at the nozzle of the spray head, avoiding the surface of the nozzle of the spray head being affected by the high temperature of the drying chamber of the powder drying equipment and drying a large amount of rose flavoring substances, which can not only ensure the quality of the preparation of rose flavoring powder, but also improve the reliability of the use of the atomization equipment.

[0016] 3. Through the nozzle cleaning mechanism and the exchange spray mechanism, after the spray head at the spray hole has been atomizing for 4 hours, the PLC controller controls the servo motor output end to rotate 180°, and at the same time, the exchange spray mechanism realizes the alternation of the two spray heads. The spray head that alternates to the spray hole continues to atomize the pure rose flavoring liquid in the booster mechanism, and the spray head that is exchanged to the normally closed valve is cleaned by the pure water in the water tank. The pure water in the water tank is sprayed to the spray head through the normally closed valve that is powered on and opened. The normally closed valve is powered on for 5 minutes to clean the dried flavoring substances on the surface of the spray head and the waste liquid after rinsing Then it flows into the filter area through the one-way drain valve, the connecting cover and the arc pipe for filtering treatment. The seasoning substances flowing into the filter area are intercepted by the filter plate and will not flow to the micro water pump. After the 5-minute countdown is completed, the PLC controller controls the normally closed valve to cut off the power and close, that is, the surface of the spray head is cleaned. The mechanism can reduce the wear rate of the spray head through the alternating use of two spray heads, thereby reducing the frequency of replacement and maintenance of the spray head of the atomizing equipment. At the same time, the atomizing equipment also has the function of automatic cleaning of the spray head that has not been atomized after alternation, which effectively improves the reliability and effect of the use of the spray equipment, and can ensure the quality of the preparation of rose yogurt seasoning powder.

[0028] The operating principle of the present invention is described as follows: when preparing rose yogurt seasoning powder, first, the PLC controller 55 controls the liquid inlet control valve 37 to open, and allows the rose seasoning stock solution to enter the opened liquid inlet control valve 37 from the pipeline, and then enter the filter cartridge 34. At the same time, the PLC controller 55 also controls the drive motor 52 to start, and the drive motor 52 rotates the transmission rod 32 through the first gear 53 and the second gear 54. The rotation of the transmission rod 32 drives the support plate 33 and the filter cartridge 34 to rotate. The rotation of the filter cartridge 34 generates centrifugal force, and the centrifugal force accelerates the rose in the filter cartridge 34. The filtration of the seasoning stock solution allows the rose seasoning stock solution to quickly pass through the filtration channel of the filter cartridge 34, while the macromolecular polysaccharides, plant fibers and some tiny rose petal residues in the rose seasoning stock solution are retained, thereby obtaining a pure rose seasoning stock solution. In addition, these macromolecular polysaccharides, plant fibers and some tiny rose petal residues can be prevented from entering the spray head 76 along with the rose seasoning stock solution, thereby preventing the spray channel of the spray head 76 from being blocked, thus not affecting the drying process of the rose seasoning powder, not causing production interruption, and not causing some materials to deteriorate due to long-term retention. The pure rose flavoring stock solution is then transported to the inside of the boosting cylinder 62 through the delivery pipe 61, and the cross bar 65 of the boosting cylinder 62 is driven to rotate by the transmission rod 32 through the second bevel gear 66 and the first bevel gear 38. After the cross bar 65 rotates, it will drive the spiral blade 67 and the sealing spiral strip 68 to rotate. The rotating spiral blade 67 and the sealing spiral strip 68 will push the pure rose flavoring stock solution in the boosting cylinder 62 to be transported to the spray head 76 of the two-way counterbore 75. Since the inner diameter of the spray channel of the spray head 76 is small and the rose flavoring stock solution transported by the boosting cylinder 62 is large, the rose flavoring stock solution passing through the spray head 76 has a high pressure, and the high-pressure rose flavoring stock solution has an excellent atomization effect after passing through the spray head 76. This mechanism enables the spray equipment to have the function of separating impurities of the rose flavoring stock solution, so that the atomization equipment has the ability to prevent blocking in the process of preparing rose flavoring powder, and improves the reliability and effect of the use of the atomization equipment, and can ensure the quality of the preparation of rose yogurt flavoring powder. Moreover, during the operation of the atomizing device, the water tank 41 and the filtering area 44 at the bottom of the partition 42 are filled with pure water through the one-way water inlet valve 43. If the water tank 41 is not full, that is, the bottom of the one-way water inlet valve 43 is not blocked by the water surface, the one-way water inlet valve 43 will continue to inject water without water pressure hindrance. During the water injection process, the normally closed solenoid valve 81 is in a closed state because it is not energized, and pure water will not enter the capillary 82. After the water injection is completed, the PLC controller 55 not only controls the micro water pump 48 and the normally closed solenoid valve 81 to start, and the normally closed solenoid valve 81 will be turned on after being energized, but also controls it every 4 hours. The output end of the servo motor 72 rotates 180 degrees, and the micro water pump 48 is started to suck the pure water filtered by the filter plate 410 in the filter area 44 and transport it to the water pipe 47. Then, part of the pure water in the water pipe 47 enters the capillary 82 through the normally closed electromagnetic valve 81, and then the pure water is injected into the annular cover 83. Finally, the pure water mist is sprayed in the direction of the atomization of the rose flavoring stock solution through the water mist nozzle 84. The water mist will form a cooling zone in the spray hole 10, so as to avoid the large amount of heat inside the drying chamber of the powder drying equipment from being transferred to the outer end of the spray head 76, thereby preventing the spray head 76 from Due to the high temperature, the droplets attached to the stock solution are dried and accumulated on the side surface. At the same time, the accumulation of dried flavoring substances on the surface of the spray head 76 is avoided as much as possible, and the increase of flavoring substances is avoided to interfere with the atomization effect of the spray head 76, thereby ensuring the uniformity of the small droplets of the rose flavoring stock solution after atomization, and at the same time, it is avoided that the small droplets of the locally atomized rose flavoring stock solution are too large to produce large particles of poor quality rose flavoring powder. In addition, the pure water mist will not affect the quality of the rose flavoring substances in the atomized small droplets of the rose flavoring stock solution. Even if the rose flavoring small droplets are combined with the pure water mist droplets, only the solvent increases, and the solvent quality remains unchanged. That is, the quality of the rose flavoring in the atomized droplets of the rose flavoring stock solution remains unchanged, while the solvent is evaporated by the high temperature of the drying chamber of the powder drying equipment, ensuring that the particle size of the prepared rose flavoring powder still meets the requirements. This mechanism enables the atomizing equipment to have the function of cooling the surface of the nozzle of the spray head 76, thereby preventing the nozzle of the spray head 76 from being affected by the high temperature of the drying chamber of the powder drying equipment and drying up a large amount of rose flavoring substances, and at the same time preventing the dried rose flavoring substances from affecting the uniformity of the atomization of the rose flavoring stock solution, which can not only ensure the quality of the prepared rose flavoring powder, but also improve the reliability of the use of the atomizing equipment; After the spray head 76 at the spray hole 10 has been atomizing for 4 hours, the servo motor 72 is controlled by the PLC controller 55 to drive the fixed rod 71 and the hard rubber plate 74 to rotate 180 degrees, so that the other spray head 76 on the hard rubber plate 74 rotates to the spray hole 10 along with the rotating hard rubber plate 74, so that the exchanged spray head 76 contacts the pure rose flavoring stock solution in the booster cylinder 62 and continues to atomize the pure rose flavoring stock solution, thereby ensuring that the preparation of rose flavoring powder is continuous, and the alternating use of the two spray heads 76 can avoid the single spray head 76 from being used up. The mist head 76 is continuously impacted and worn by the rose flavoring concentrate, which reduces the frequency of replacement and maintenance of the atomizing equipment spray head 76. The spray head 76, which has been atomizing for 4 hours, is rotated by the hard rubber plate 74 to the normally closed valve 46. At the same time, the L-shaped indicator rod 77 that rotates synchronously with the spray head 76 rotates to the trigger area of ​​the proximity sensor 415. The proximity sensor 415 generates an electrical signal and sends it to the PLC controller 55. The PLC controller 55 controls the normally closed valve 46 to open for 5 minutes according to the electrical signal. Due to the opening of the normally closed valve 46, the water tank The pure water in 41 enters the curved pipe 45 due to the obstruction of the one-way water inlet valve 43 and the water pressure of the water guide pipe 47, and is sprayed to the spray head 76 through the opened normally closed valve 46, so as to automatically clean the surface of the spray head 76 and clean the dried seasoning substances on the surface of the spray head 76. The waste liquid after washing flows into the connecting cover 414 through the one-way drain valve 78, and the pure water in the connecting cover 414 also cleans the other side of the spray head 76, and finally returns to the connecting rod 412 of the filter area 44 through the arc pipe 413, and the seasoning substances flowing into the filter area 44 are washed by the The retained water on the filter plate 410 will not flow to the micro water pump 48. After the 5-minute countdown is completed, the PLC controller 55 controls the normally closed valve 46 to shut down and shut down, indicating that the surface of the spray head 76 is cleaned. The mechanism can reduce the speed at which the spray head 76 is worn by alternating the two spray heads 76, thereby reducing the frequency of replacement and maintenance of the spray head 76 of the atomizing equipment. At the same time, the atomizing equipment also has the function of automatically cleaning the spray head 76 that is not atomizing after alternation, thereby effectively improving the reliability and effect of the use of the spray equipment and ensuring the quality of the preparation of the rose yogurt seasoning powder.
