Description

a coffee filter

technical field

The utility model relates to an infusion-type coffee filter, which is straddled on a cup and is infused with hot water to extract coffee liquid.

Background technique

There are roughly three ways to make coffee at home: instant, filter, and brewed. Instant coffee is generally made by pouring coffee, creamer and sugar powder (commonly known as three-in-one coffee) into a cup and then brewing. This kind of coffee is less able to bring out the aroma of coffee. Brewed coffee is made by using a coffee machine, and the price of the coffee machine varies greatly depending on the function and the professional level of cooking, and the taste of the brewed coffee is also different. Therefore, the popular common Coffee machine is a widely used machine; however, even the most popular coffee machine, there are many procedures when using it, and it is troublesome to clean after use, so some people are not keen on using coffee machine.

Filter coffee is a choice between coffee machines and instant coffee. It is characterized in that it provides a filter coffee maker body shaped into a conical body with an inner space. The bottom or surrounding of the coffee maker body The side wall is provided with holes; when in use, put the coffee machine body directly on the cup mouth, then put filter paper in the inner space of the coffee machine body, and put the ground coffee powder into the filter paper, then Pour boiling water into the filter paper in the main body of the coffee machine, let the hot water slowly pass through the coffee powder, and the hot water flows out of the hole in the bottom or side wall of the main body and drips into the cup, that is, the synthetic components in the coffee are extracted and finally obtained Strong, mellow and fragrant filter coffee.

Another kind of filter coffee machine body is made of sheet-shaped stainless steel material with etching technology to create a plurality of extremely fine holes, and then the stainless steel sheet with countless holes is formed into a conical funnel shape; when in use, Put the coffee powder directly into the coffee machine body, then pour hot water slowly through the coffee powder, the hot water flows out of the hole in the body and the coffee liquid is extracted and drips into the cup.

No matter which kind of filter coffee machine is mentioned above, when brewing coffee, the boiling water is rushed into the coffee machine body and leaks through the hole at the bottom immediately after passing through the coffee powder, so that when the boiling water stays in the coffee powder It is not enough to extract the full essence of coffee, so filter coffee is often still slightly inferior to brewed coffee in taste.
