Embodiment Construction

[0023] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0024] As shown in Figures 1, 2, and 3.

[0025] A brewing device for producing foam, crema or crema at low pressure, comprising a mesh screen lid 9, coarse filter 3, fine filter 8, large O-ring 10, coffee container 4, small O-ring ring 5, and a foam generator 6 with a plurality of small holes. In a preferred embodiment, the mesh lid 9 and coffee container 4 are made of plastic, such as polyoxymethylene, the primary filter 3 is made of metal, such as stainless steel, the fine filter 8 is made of nylon, and the large and small O-rings Made of synthetic rubber, such as silicone rubber.

[0026] The top surface of the mesh cover 9 has a plurality of small holes, and a mesh made of metal such as stainless steel is attached to the underside of the top surface. If the mesh cover 9 is plastic and the mesh is metal, the mesh cover 9 can hold the metal mesh o...

Abstract

The present invention pertains to a brewing filter apparatus capable of preparing foam, froth, or crema, particularly for coffee beverages, under low pressure. The apparatus can operate at pressures below 15 bar and as low as 1-3 bar. The apparatus comprises a filter, coffee container, O-ring, and foam maker having two opposing holes. The holes have a diameter in the range of 0.3 to 1 mm. The crema is created by the turbulent contacting of two opposing jets of coffee. To further increase agitation and the surface area for contact, a stainless steel wire mesh may be situated in the center of the foam maker directly in the path of and between the opposing jets of coffee to facilitate the formation of more crema.

Description

technical field [0001] The present invention relates to an infusion filter capable of producing foam, crema or crema, especially for coffee beverages, under low pressure conditions, and in particular to an infusion filter for producing foam, crema or crema under low pressure conditions Brewing equipment. Background technique [0002] Currently, coffee beverages with a thick layer of foam known as "crema" are gaining popularity among coffee drinkers and coffee lovers. Similar to the foam on a stout, the crema is aromatic and lingering. Typically, coffee drinks such as espresso made under high pressure (15-19 bar) will have a layer of crema. This layer of crema is fragrant and delicate, with a hint of coffee flavor and a pleasant taste. This layer of crema is like a blanket that wraps the coffee drink's pleasant aroma and flavor so that it does not evaporate quickly. [0003] The general method that current technology adopts is to use high-pressure brewing method and instr...
