Coffee powder and coffee filter for trickling filtration and extraction of coffee powder

Abstract

The invention relates to coffee powder and a coffee filter for trickling filtration and extraction of the coffee powder. The coffee powder provided by the invention is obtained by the steps of carefully selecting coffee beans which are complete in granules, plump, free from worms and free from mildew, performing thorough cleaning, and performing natural drying to obtain coffee bean raw materials;performing moderate baking on the coffee bean raw materials to obtain baked beans of which the caramelization Ag value is 60-65; and performing moderate grinding on the baked beans to obtain the coffee powder of which the particle diameter is 0.450-0.65mm. Through such baking and grinding processes, the obtained coffee powder is moderate in soaking consistency, and pure in fragrance, through cooperation of the coffee filter for trickling filtration and extraction of the coffee powder, filtration is performed through nonwovens, through design of a trickling filtration opening, the extraction degree of the coffee powder in the soaking process can be guaranteed, coffee liquid is subjected to slow trickling filtration to a cup, and the trickling filtration speed is moderate. Through functionsof being quantitative, timing, fixed in flow rate and the like, the coffee can be perfectly extracted, and each user only needs to inject enough hot water, a cup of standard quality-good coffee can beimmediately soaked. The coffee filter is simple to operate.

Description

technical field [0001] The invention relates to the technical field of coffee powder and drip coffee cups, in particular to coffee powder and a coffee filter for extracting the coffee powder by drip filtration. Background technique [0002] With the increasing volume of coffee in the Chinese market, the coffee industry has developed rapidly. In 2018, the coffee market revenue exceeded 100 billion. The people's understanding and demand for coffee are also increasing, and they are gradually migrating from instant coffee products to ground coffee products. The freshly ground coffee market has grown explosively and is far from saturated. In today's society where the pace of work and life is getting faster and faster, coffee brewing is no longer limited to the method of freshly ground and brewed coffee, such as the two types of self-brewed and portable coffee bags that have been developed now; One is the ear bag coffee: the ground coffee powder is stored in a non-woven bag, and ...

AI Technical Summary

Problems solved by technology

[0003] Generally speaking, the taste of coffee is determined by factors such as brewing temperature, extraction time, and grinding degree, but now the market is mainly demanding for portable specialty coffee; that is to say, both taste and portability must be considered. The ear-hanging type and freeze-dried instant coffee powder are at a loss in terms of taste and portability design, because they cannot take into account the drip filter and extraction design on the portable brewing equipment, making the coffee powder and brewing equipment The double combination of extraction time and drip filter effect cannot be achieved, which makes the brewing of portable coffee taste uneven and poor in taste
