Description

Technical Field

[0001] The utility model relates to the technical field of food processing, in particular to a novel hygienic food-grade compressed air filtering and distributing station. Background Art

[0002] In the modern food and beverage manufacturing industry, compressed air is an important public utility with a wide range of applications, covering all stages from raw material processing, production and processing to product packaging. Especially in the fermentation industry, the quality of compressed air is directly related to the success or failure of the fermentation process and the quality of the final product. However, although the importance of compressed air is self-evident, in actual applications, compressed air that has not been fully purified often carries various pollutants, posing a major challenge to production safety and product quality.

[0003] In the related art, during the process of compressing air, air compressors will inevitably suck in and compress impurities in the atmosphere, including but not limited to solid particles, oil mist, water vapor and various chemicals. According to statistics, there are about 140 million particles per cubic meter of air in the natural environment, most of which are less than 2 microns in diameter. This size allows them to easily penetrate most primary filters and enter the subsequent production system with compressed air. In addition, the metal parts inside the air compressor system will wear out after long-term operation, and the resulting grinding debris and rust residue will be mixed into the compressed air. The continuous accumulation of these impurities will damage the air-using equipment, accelerate the aging of the equipment, and even cause seal failure and performance degradation.

[0004] In some related technologies, in order to reduce the friction inside the air compressor and extend the life of the equipment, the compressor often uses oil lubrication. Although the oil separator is designed to separate the oil mist from the compressed air, under high pressure and high temperature environment, some of the oil mist cannot be completely separated. These oil mists will be sent to downstream equipment along with the compressed air, which will not only pollute the production environment, but also may affect the microbial activity of the fermentation process, thereby affecting the quality and safety of the product.

[0005] In addition, the water vapor carried in the compressed air will condense into liquid water after cooling, forming the so-called "wet saturated air". In an environment with a relative humidity of more than 65%, the moisture content in the compressed air is particularly significant. This moisture not only increases the volume of the compressed air and reduces its efficiency, but also when the moisture condenses, the liquid water droplets formed will accumulate in the pipes and equipment, causing rust problems, corroding metal materials, and affecting the reliability and service life of the equipment.

[0006] Therefore, in response to the special needs of the fermentation industry, the development of a sanitary food-grade compressed air filtration and distribution station that can effectively remove various impurities in compressed air and ensure the purity of compressed air, while also having safe drainage, explosion-proof, pressure monitoring, filtration, cleaning and disinfection functions, is of great significance for improving production efficiency, ensuring product quality and production safety.

[0039] In the modern food and beverage manufacturing industry, compressed air is an important public utility with a wide range of applications, covering all stages from raw material processing, production and processing to product packaging. Especially in the fermentation industry, the quality of compressed air is directly related to the success or failure of the fermentation process and the quality of the final product. However, although the importance of compressed air is self-evident, in actual applications, compressed air that has not been fully purified often carries various pollutants, posing a major challenge to production safety and product quality.

[0040] In the related art, during the process of compressing air, air compressors will inevitably suck in and compress impurities in the atmosphere, including but not limited to solid particles, oil mist, water vapor and various chemicals. According to statistics, there are about 140 million particles per cubic meter of air in the natural environment, most of which are less than 2 microns in diameter. This size allows them to easily penetrate most primary filters and enter the subsequent production system with compressed air. In addition, the metal parts inside the air compressor system will wear out after long-term operation, and the resulting grinding debris and rust residue will be mixed into the compressed air. The continuous accumulation of these impurities will damage the air-using equipment, accelerate the aging of the equipment, and even cause seal failure and performance degradation.

[0041] In some related technologies, in order to reduce the friction inside the air compressor and extend the life of the equipment, the compressor often uses oil lubrication. Although the oil separator is designed to separate the oil mist from the compressed air, under high pressure and high temperature environment, some of the oil mist cannot be completely separated. These oil mists will be sent to downstream equipment along with the compressed air, which will not only pollute the production environment, but also may affect the microbial activity of the fermentation process, thereby affecting the quality and safety of the product.

[0042] In addition, the water vapor carried in the compressed air will condense into liquid water after cooling, forming the so-called "wet saturated air". In an environment with a relative humidity of more than 65%, the moisture content in the compressed air is particularly significant. This moisture not only increases the volume of the compressed air and reduces its efficiency, but also when the moisture condenses, the liquid water droplets formed will accumulate in the pipes and equipment, causing rust problems, corroding metal materials, and affecting the reliability and service life of the equipment.

[0043] Therefore, in response to the special needs of the fermentation industry, the development of a sanitary food-grade compressed air filtration and distribution station that can effectively remove various impurities in compressed air and ensure the purity of compressed air, while also having safe drainage, explosion-proof, pressure monitoring, filtration, cleaning and disinfection functions, is of great significance for improving production efficiency, ensuring product quality and production safety.

In some applications, normally closed valves are set between the steam disinfection pipeline 410 and the CIP cleaning pipeline 420 and the ventilation pipeline, and the operator needs to actively open them in the application to disinfect and clean the ventilation pipeline.

[0045] Refer to Figure 1 The first filter element 310 and the second filter element 320 are both mounted in a snap-fit ​​manner with the filter section 120, allowing for quick replacement and maintenance of the filter elements, reducing downtime and improving production efficiency.

In some embodiments, the first filter element 310 and the second filter element 320 are PP folded filter elements. Furthermore, the first filter element 310 and the second filter element 320 are both connected to a drain pipe 330 for draining water outwards.

For example, the two ends of the pipeline portion corresponding to the air intake control valve 220 are connected by a clamping joint 700, and the two ends of the pipeline portion corresponding to the pressure reduction control switch 230 are connected by a clamping joint 700. Similarly, the filter section 120 is a split detachable pipeline structure to install or maintain the first filter element 310 and the second filter element 320 respectively. For example, the two ends of the pipeline portion corresponding to the first filter element 310 are connected by a clamping joint 700, and the two ends of the pipeline portion corresponding to the second filter element 320 are connected by a clamping joint 700. Furthermore, the air intake control valve 220, the pressure reduction control switch 230, the first filter element 310 and the second filter element 320 are allowed to be maintained separately, which improves the flexibility and maintenance efficiency of the system. In some embodiments, a service valve 340 is provided between the first filter element 310 and the second filter element 320 to further improve the service and maintenance efficiency.

The regulating accuracy of the second regulating valve 540 is higher than that of the first regulating valve 510.

The higher regulating accuracy of the second regulating valve 540 ensures accurate control of the oxygen supply to the fermentation liquid in the fermentation tank experiment, optimizes the fermentation conditions, and promotes the improvement of fermentation efficiency and product quality.
