Coffee filter paper industry definition
Coffee filter paper is a kind of paper specially used for brewing coffee. It can filter out impurities and sediments in coffee, making the brewed coffee clearer and tastier. The selection of coffee filter paper can be considered from the dimensions of water permeability, taste, and brewing compatibility. There are many good filter paper brands, a bit like the matching relationship between camera film and camera in the early years.
Coffee filters are made of filter paper weighing about 100 g/m2. The raw material of this filter paper is coarse and long fibers, which are usually derived from fast-growing trees. During the manufacturing process, the filter paper can be bleached or left unbleached. Typically, coffee filters are made of filaments about 20 microns wide, and the gaps between these filaments allow particles smaller than 10 to 15 microns to pass through, thereby achieving the filtering effect of coffee.
For filters to be compatible with coffee machines, they must have specific shapes and sizes. In the United States, common filter types include cone filters #2, #4, and #6, as well as basket filters for 8-12 cups for home use and larger restaurants. These different sizes and types of filters ensure convenience and consistency in the coffee making process.
Coffee filters can be classified based on their treatment and brand. Depending on whether they are bleached or not, coffee filters can be divided into two types: bleached and unbleached. Bleached coffee filters appear whiter, while unbleached filters appear light brown.
Coffee filter paper industry classification
The upstream of coffee filter paper is mainly raw material suppliers, including pulp and paper processing equipment. The quality and stability of these raw materials and equipment directly affect the quality and production efficiency of coffee filter paper. The downstream application industries of coffee filter paper are mainly concentrated in the coffee beverage manufacturing industry, especially the hand-brewed coffee market. Coffee filter paper filters out impurities and sediments in coffee, making the brewed coffee clearer and tastier. In addition, as consumers’ requirements for coffee quality increase, more and more coffee shops and families begin to use high-quality coffee filter paper to improve the taste and quality of coffee.
