Description

Technical Field

[0001] This utility model relates to the field of vinegar production technology, specifically a sterilization and disinfection device for vinegar production. Background Technology

[0002] Vinegar is an acidic condiment produced through various fermentation processes and is a weak electrolyte. Vinegar brewing primarily uses rice or sorghum as raw materials. Appropriate fermentation converts liquids containing carbohydrates (sugar, starch) into alcohol and carbon dioxide. The alcohol then combines with oxygen in the air under the action of certain bacteria to produce acetic acid and water. Therefore, the vinegar brewing process is essentially the further oxidation of alcohol into acetic acid. Vinegar has a sour and mellow taste, and a fragrant and smooth aroma. It is an indispensable condiment in cooking, and its main components are acetic acid and higher alcohols. my country is a major producer and consumer of vinegar, with a long history of vinegar brewing. Many people have the habit and fondness for vinegar. Over the years, vinegar production processes have become diverse. To ensure the quality of vinegar and extend its shelf life, it needs to be sterilized after fermentation before bottling, usually requiring sterilization equipment. Most existing vinegar production sterilization equipment uses instantaneous steam sterilization, but this has the problem of insufficient contact between steam and vinegar, resulting in poor sterilization. Furthermore, the high-temperature vinegar is not rapidly cooled after sterilization, reducing production efficiency. Therefore, there is a need to develop a sterilization and disinfection device for vinegar production that can ensure full contact between steam and vinegar, thereby improving sterilization quality and production efficiency.

A discharge pipe 16 is connected to the lower end of the sterilization tank 1, and a discharge valve 17 is connected to the discharge pipe 16. An inlet is opened at the top of the raw vinegar tank 11, and an end cap is detachably connected to the inlet. The bottom of the sterilization tank 1 is inclined downwards towards the discharge pipe 16. A vinegar inlet plate 4 is fixedly connected to the upper part of the sterilization tank 1, and several nozzles 5 are connected to the lower end of the vinegar inlet plate 4. A steam main pipe 2 is rotatably connected to the sterilization tank 1 via bearings. The steam main pipe 2 is driven by a motor 9. The lower end of the steam main pipe 2 passes through the vinegar inlet plate 4 and is connected to several steam branch pipes 3 via pipes. Several nozzles are opened on the steam branch pipes 3. The steam generator 7 has a steam outlet. The upper end of the steam main pipe 2 passes through the sterilization tank 1 and is fixedly connected to the rotary joint 8. The upper part of the rotary joint 8 is fixedly connected to the top of the sterilization tank 1 via a connecting bracket. The outlet end of the steam generator 7 is fixedly connected to the upper end of the rotary joint 8 via an air inlet pipe 10. The lower end of the original vinegar tank 11 is connected to the heat exchange box 14 via the original vinegar pipe 12. A first delivery pump 13 is connected to the original vinegar pipe 12. The other side of the heat exchange box 14 is connected to the vinegar inlet plate 4 via an inlet pipe 6. A second delivery pump 18 is connected to the inlet pipe 6. A spiral coil 15 is fixedly connected inside the heat exchange box 14. The discharge pipe 16 is connected to the inlet end of the spiral coil 15. The outlet end of the spiral coil 15 is connected to the storage tank 24 via a pipe. It should be noted that in this embodiment, the steam generator 7 is an existing device that can set the temperature of the delivered steam to ensure the sterilization effect while maintaining the best taste and flavor of the vinegar. The specific structure of the steam generator 7 will not be described in detail here. Meanwhile, the rotary joint 8 is an existing device that can transport gaseous and liquid materials while rotating, and its specific structure will not be described in detail here.

[0016] To further disinfect and sterilize the vinegar and improve its sterilization effect, an ultraviolet disinfection box 19 is also included. The inner two side walls of the ultraviolet disinfection box 19 are fixedly connected with inclined downward guide plates 20 from top to bottom. A flow channel is opened between the guide plates 20 and the other side wall of the ultraviolet disinfection box 19. Ultraviolet disinfection lamps 21 are fixedly connected to the top of the ultraviolet disinfection box 19 and the bottom of the guide plates 20. The outlet end of the spiral coil 15 is connected to the upper part of one side of the ultraviolet disinfection box 19 through a pipe. The lower part of the other side of the ultraviolet disinfection box 19 is connected to the storage tank 24 through a receiving pipe 22. A third conveying pump 23 is fixedly connected to the receiving pipe 22.

[0017] To ensure proper sterilization by rotating the steam main pipe 2 via the motor 9, thereby maximizing the contact between the steam and vinegar, the motor 9 is bolted to the top of the sterilization tank 1. A first bevel gear is fixedly connected to the output end of the motor 9, and a second bevel gear is fixedly connected to the steam main pipe 2. The first and second bevel gears mesh and drive each other. It should be noted that in this embodiment, the motor 9 and the steam main pipe 2 can also be driven by a belt and pulley, a chain and sprocket, or other similar means.

[0018] To ensure safety during the sterilization process and maintain a constant pressure inside the sterilization tank 1 to guarantee a better sterilization effect, a safety valve 25 is connected to the upper end of the sterilization tank 1.

[0019] In order to improve heat exchange efficiency, quickly reduce the temperature of the sterilized vinegar, and at the same time make the most of the heat from the steam sterilized vinegar to increase the temperature of the raw vinegar and improve production efficiency, the feeding direction of the spiral coil 15 is opposite to that of the heat exchange box 14. The high-temperature vinegar in the spiral coil 15 flows from right to left, while the raw vinegar in the heat exchange box 14 flows from left to right.

[0020] It should be noted that in this embodiment, if vinegar can be transported on other pipelines based on the height difference, then a transport pump is not needed. If vinegar cannot be transported based on the height difference, then a transport pump can be installed to transport vinegar. At the same time, valves can be installed on the pipelines according to usage requirements.

[0021] The working process of this embodiment is as follows:

[0022] During vinegar sterilization, vinegar is first added to the original vinegar tank 11, and the first delivery pump 13 is started. The vinegar enters the heat exchange box 14 through the original vinegar pipe 12. Simultaneously, the second delivery pump 18 is started, and the vinegar enters the vinegar inlet plate 4 through the vinegar inlet pipe 6 and is sprayed out from the nozzle 5 into the sterilization tank 1. The steam temperature is set in advance on the steam generator 7. Steam enters the steam main pipe 2 through the air inlet pipe 10 and exits through the air outlet on the steam branch pipe 3. Simultaneously, the motor 9 is started, and the motor 9 drives the first bevel gear to rotate. The first bevel gear drives the second bevel gear and the steam main pipe 2 to rotate, which in turn drives the steam branch pipe 3 to rotate. This process can achieve full contact sterilization between steam and vinegar, ensuring a good sterilization effect. After steam instantaneous sterilization, the discharge valve 17 on the discharge pipe 16 is opened, and the high-temperature vinegar enters the spiral coil 15 to exchange heat with the raw vinegar in the heat exchange box 14 to cool down. This not only achieves rapid cooling of the sterilized high-temperature vinegar, but also makes full use of its heat to initially heat up the raw vinegar, improving work efficiency. Then, it enters the ultraviolet disinfection box 19 and flows once on the guide plate 20. At the same time, the ultraviolet disinfection lamp 21 is turned on to further sterilize the vinegar and improve sterilization efficiency. Then, the third delivery pump 23 is started to make the vinegar enter the storage tank 24 through the receiving pipe 22.
