Problems solved by technology
[0002] In the extraction process of espresso, hot water is mostly used to extract the ground coffee powder, but under normal pressure, the coffee solution extracted only by hot water usually cannot meet the concentration requirements of espresso
In addition, coffee powder also contains crema, which is usually composed of vegetable oil, protein and sugar; coffee crema will greatly improve the taste and taste of coffee, but coffee crema usually cannot be effectively processed by hot water under normal pressure. extraction

Embodiment
[0023] Example: such as figure 1 and figure 2 As shown, this embodiment specifically relates to a multi-stage pressure extraction method for coffee. The method uses the extraction cup 1 and the matched powder head 2 to extract the ground coffee; the extraction cup 1 is provided with several A filter plate 3 with a mesh; the filter plate 3 separates the extraction cup 1 into a primary extraction chamber 4 located above and a secondary extraction chamber 5 located below, the liquid in the primary extraction chamber 4 can pass through the mesh on the filter plate 3 The hole enters the secondary extraction chamber 5. The powder pressing head 2 is movably inserted in the opening on the top of the first-stage extraction chamber 4, and the side wall of the powder pressing head 2 and the inner wall of the first-stage extraction chamber 4 form a sealed fit to make it a chamber capable of forming high pressure, preventing the extraction process from Medium water vapor leaks from the ...

The invention discloses a multilevel pressure extraction method of coffee. The method comprises the following steps that an extraction cup is divided into a first order extraction warehouse and a second order extraction warehouse through a filter plate with a plurality of meshes; the ground coffee inside the first order extraction warehouse is squeezed into the coffee powder and an enclosure space is generated inside the extraction warehouse; the hot water is poured into the first order extraction warehouse with high pressure and the coffee powder is infiltrated by the hot water;when the pressure in the first order extraction warehouse is higher than the extraction threshold value of the filter plate, the hot water passes through the coffee powder and then the hot water is formed as the extract liquor; the extract liquor passes through the filter plate and then flows into the second order extraction warehouse; when the pressure in the second order extraction warehouse is higher than the second order extraction threshold value of the counterbalance valve located at the liquid outlet of the second order extraction warehouse, the counterbalance valve is opened under the pressure action and the extraction liquid is eliminated from the counterbalance valve. The multilevel pressure extraction method of coffee has the advantage that the ground coffee utilizes the depth extraction with multilevel pressure to extract the effective constituents unable to require under the ordinary pressure, which improves the flavor and the taste of the coffee.
Description
technical field [0001] The invention belongs to the field of food processing, and in particular relates to a multistage pressure extraction method for coffee. Background technique [0002] In the extraction process of espresso, hot water is mostly used to extract the ground coffee powder, but under normal pressure, the coffee solution extracted only by hot water usually cannot meet the concentration requirement of espresso. In addition, coffee powder also contains crema, which is usually composed of vegetable oil, protein and sugar; coffee crema will greatly improve the taste and taste of coffee, but coffee crema usually cannot be effectively processed by hot water under normal pressure. extraction. Contents of the invention [0003] The object of the present invention is to provide a multi-stage pressure extraction method for coffee according to the shortcomings of the above-mentioned prior art. The multi-stage pressure extraction method for coffee can extract difficult-...
