Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of purification equipment, and in particular relates to a defoaming device for a food purification machine. Background Technology
[0002] The cleaning process is crucial in meat processing, effectively removing blood, grease, meat scraps, and surface scum to ensure food safety and hygiene. Traditional meat cleaning equipment often uses high-pressure spraying or immersion cleaning, but during this process, the dissolution of meat proteins and fats easily generates a large amount of foam. This foam not only reduces cleaning efficiency but can also clog drainage systems and even contaminate subsequent processes.
[0003] Currently, common defoaming methods mainly include mechanical scraping, the addition of chemical defoamers, or natural settling. However, mechanical scraping devices are complex in structure and difficult to completely remove fine foam; chemical defoamers may introduce food safety hazards; and natural settling is inefficient and cannot meet the high-efficiency requirements of modern meat processing.
[0004] Therefore, there is an urgent need for a defoaming device for food purifiers that can automatically separate and remove foam during the washing process, while also possessing characteristics such as simple structure, easy cleaning, and no chemical additives, to meet the stringent requirements of the food processing industry for high efficiency, safety, and environmental protection. To address these issues, we propose a defoaming device for food purifiers. Utility Model Content
[0005] The purpose of this invention is to provide a defoaming device for a food purification machine to solve existing problems.
[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

A baffle is fixedly connected to the upper end face of the defoaming tank, and a defoaming machine is fixedly connected to the upper end face of the baffle. The output end of the defoaming machine extends through the baffle into the defoaming tank. A first filter plate and a second filter plate are fixedly connected to the right end of the connecting plate and are fixedly connected to the circulating water tank. A fine filter barrel is fixedly connected to the lower side of the right end face of the inner wall of the circulating water tank. A water pump is fixedly connected to the right end face of the outer wall of the circulating water tank, with its input end penetrating the circulating water tank and fixedly connected to the fine filter barrel.

[0009] This utility model has the following beneficial effects:
[0010] This invention adds a dedicated defoaming tank to the outside of the circulating water tank of the purifier. This provides a buffer space for the foam, and automated foam removal is achieved by using an overflow defoaming port within the tank. When the foam level exceeds the preset overflow defoaming port, the floating foam on the surface automatically flows into the overflow defoaming port, thus smoothly discharging it outside the equipment and preventing foam accumulation and overflow.
[0011] This invention achieves defoaming by using a defoaming machine fixedly connected above the defoaming tank. The defoaming machine utilizes high-speed rotation to quickly draw foam floating on the water surface into the equipment and break it up mechanically, achieving efficient defoaming. This improves the efficiency of foam treatment and ensures the clarity and purity of the purified water.
[0012] By organically combining defoaming tanks, overflow defoaming, and defoaming machines, a highly efficient, stable, and easy-to-maintain foam elimination system is formed. This system not only solves the problem of foam overflow and inability to remove it during continuous production, but also avoids potential problems such as site pollution, providing strong technical support for the purification and treatment of fresh food.
