Description

Outdoor DIY coffee extractor

Technical Field

The utility model relates to a coffee extractor technical field especially relates to an it is outdoor with DIY coffee extractor.

Background

Most of various coffees sold in coffee shops are prepared by adding various ingredients into concentrated and extracted basic materials. The implement-oriented conditions for high-quality concentration extraction are as follows: the pressure of a punch is 9 +/-1 bar, the extraction is carried out for 20-30 seconds, and the temperature of water is higher than 90 ℃. Coffee machines in the market, classified according to the place of use: first, indoor coffee machine, bulky, heavy, need have the power. And the outdoor coffee machine has small volume and light weight, and provides compression power by using a compressed gas tank, an inflator, hand-pinching inflation and the like. These require energy expenditure or difficult to reach pressures of 9bar, and the pressures are not stable, resulting in difficulties in controlling both the quality of the extraction and the extraction time. The invention adopts the following steps: a person with a weight of 60 kg presses on an area with a diameter of 28mm, so that the pressure is about 9.5Bar, and the pressure is stable because the weight of the person is not changed in the extraction process. Through the design of the nozzle, according to the single cup capacity of 25-30 ml, the stroke extraction time of human body pushing down can be controlled between 20-30 seconds.

For temperature issues. In general geographic environments, boiled water is 99-100 ℃, heat is lost in the process of pouring the boiled water, and in addition, the temperature of the cup body is lower than 35 ℃, which is far lower than that of boiled water, and the temperature of the water is reduced due to the fact that the cup body absorbs the heat. Although commercial non-electric coffee extraction products suggest that the extraction concentrate is first warmed up in the extraction cup, this is not easily done in outdoor operations and is difficult to reach or exceed the hot 45 c temperature regardless of how the warming up is done. The boiled water capacity designed by the outdoor coffee maker on the market is very small, the heat capacity of the boiled water is low due to the small water capacity, the problem that the temperature of the boiled water is lower than 85 ℃ exists after the heat of the heating cup body is consumed, and even the temperature is lower than 75 ℃ in cold days.

The sequence of making various coffee machines on the market is as follows: firstly, making concentrated coffee, then adding seasonings and blending to obtain various tastes. The blending process requires the use of cups, and the outdoor conditions cannot meet the use of multiple cups.
