Description

Technical Field

[0001] This utility model relates to the technical field of beer filter paperboard, specifically an environmentally friendly beer filter paperboard. Background Technology

[0002] Beer filter paper is a fine filter material specifically designed for beer filtration. Its main function is to remove yeast cells, proteins, and other turbidity from beer to ensure its clarity and stability. It is typically made of refined cotton, high-quality wood pulp, food-grade filter aids (such as diatomaceous earth and perlite), and wet strength agents. Primarily used for beer clarification filtration to ensure its clarity and stability, it can also be used for clarifying and filtering wine, juice, and beverage syrups. Beer filter paper plays a crucial role in the beer brewing process, ensuring the quality and taste of the beer.

[0003] Common beer filter paperboards have a relatively simple structure and limited functionality. They usually lack positioning structures, which can lead to misalignment during filtration, resulting in uneven filtration and even causing some areas of the filter media to fail, thus affecting the filtration effect. During installation and disassembly, paperboards without positioning frames are more susceptible to mechanical damage, such as splintering and tearing, which shortens the lifespan of the paperboard and has certain adverse effects on users. Therefore, we propose an environmentally friendly beer filter paperboard. Utility Model Content

[0004] Technical Problem Solved: Addressing the shortcomings of existing technologies, this utility model provides an environmentally friendly beer filter paperboard with advantages such as positioning and enhanced performance. The filter paperboard is positioned by inserting it into the inner side of a U-shaped groove. The inner side of the U-shaped groove has an anti-slip flexible pad to enhance slip resistance. The paperboard positioning frame is inserted into the inner side of the positioning U-shaped groove. The positioning block, through the action of its rear elastic damping element, can be engaged with the inner side of the positioning slot for positioning with the outer positioning frame. The limiting plate inside the inner movable groove acts as a limit to prevent detachment, helping the filter paperboard to be accurately positioned in the filtration equipment, ensuring consistent position each time it is installed, thereby improving the filtration effect and the stability of equipment operation. The paperboard positioning frame increases the overall structural strength of the filter paperboard, preventing deformation or damage caused by pressure or physical impact during use, extending the service life of the filter paperboard. At the same time, installing and replacing the filter paperboard becomes simpler and faster, allowing operators to more easily and correctly install the filter paperboard, reducing installation time. The filter paperboard features a biodegradable pre-filtration layer, a nanofiber microporous filtration layer, an activated carbon adsorption layer, a natural antibacterial layer, a natural antioxidant layer, and a hydrophilic plant fiber layer. The biodegradable pre-filtration layer removes large particles, reducing the burden on subsequent filtration layers, and its biodegradability reduces environmental pollution. The nanofiber microporous filtration layer removes smaller particles and suspended solids, improving beer clarity. Nanocellulose, derived from plant fibers, is renewable and environmentally friendly. The activated carbon adsorption layer adsorbs organic matter and pigments in beer, improving its color and taste. The natural antibacterial layer prevents microbial growth, extending the beer's shelf life. Bamboo fiber is renewable and environmentally friendly. The natural antioxidant layer prevents oxidation reactions in beer, maintaining its freshness and flavor. Green tea extract, derived from natural plants, is environmentally friendly and harmless. The hydrophilic plant fiber layer promotes beer flow, reduces filtration resistance, and improves filtration efficiency. Cotton fiber is renewable and environmentally friendly, effectively addressing the problems mentioned in the background technology.
