Making a coffee machine with your own hands

It is impossible to reproduce the device of an electric coffee machine with your own hands precisely - in modern devices the vapor pressure reaches ten atmospheres, and the circuit of electronic metering devices is very complicated. Consider a few simple solutions that are available for implementation at home.

Geyser type coffee machine

The simplest one is a geyser-type coffee machine. The simplest is the main unit responsible for making coffee. Such a self-made coffee maker looks like this:

1. Below is the water tank.
2. A two-chamber unit is installed on it, the lower part of which is a container for ground coffee, the upper part is a compartment for a ready-made drink.

Such a homemade coffee machine works simply: when the liquid is heated, the steam passes through the ground coffee,and the resulting beverage enters the upper compartment through a vertical tube. As you accumulate, you can pour it into a cup and enjoy the taste. The design scheme is presented in the photo.

The principle of operation of geyser-type coffee makers

The self-made coffee machine of this class is equipped with heating elements made of nichrome wire. In practice, to reduce labor intensity, you can go a simple way - to adapt the lower heating plate from electric kettle. This solution is very profitable:

• temperature is controlled;
• An internal security system, which is present in many heating elements, will prevent the possibility of emergency situations.

Geyzernaya homemade coffee machine served as a prototype of a serial product, which produced the Soviet industry.

There were also coffee machines for motoristsable to make a cup or two of flavored drink with a cigarette lighter.

Patented version of the homemade coffee machine

We note right away: the answer to the question of how to make a coffee machine with a full cycle with your own hands is not found. The most effective option involves the separation of operations. Separately, a grain mill is made; as the simplest solution, a steel screw auger can be used to grind spices. There are also instruments with electric and manual drives, however, there is not much difference between them.

Prepared ground coffee is poured into a homemade coffee maker. One of the interesting developments for which the patent was even obtained is the device of engineer Vladimir Oreshkin. This is a solid double-walled chamber made of a solid billet and equipped with an outlet pipe for draining the finished beverage.

To prepare an espresso, a steel container with water is placed inside and a portion of ground coffee is poured. The lid is securely closed, it has no sealing gaskets - the principle of milling is implemented. When the container is heated, there is a full Effect coffee steaming, which allows you to achieve a rich taste and aroma of espresso. In the original model of a homemade coffee maker, it was intended to be installed on a gas stove.

Based on this development, many craftsmen have come up with improved versions of coffee machines. They added their own heaters, both electrical type, and with the use of alcohol, paraffin burners.

Such a device can be a very attractive companion for those who prefer hiking and extreme travel to other ways of spending time.

Controversial constructions

On the Internet, you can find more than one and not two options for making your own coffee machine. For example, from forum to forum wanders mini espresso machineIn which there is everything: own alcohol burner for water heating, a container for coffee, a convenient faucet for discharging a drink. In this case, the device can be easily placed in a pocket. You can see this mini-maker in the photo.

However, the specific design requires the use of welding, copper tubes, unique components, empirically selected dimensions. Therefore, to guarantee that everyone can make this coffee maker, it is impossible. Including because in the role of the heater is used alcohol burner, but no parameters of the device refinement for the use of kerosene, gasoline or paraffin are given.

There are also successful projects that look almost like a serial industrial product, for example, on the Internet they vividly discuss the stylish coffee maker of the German handicraft master.

In its design, a great number of assemblies are assembled, which are taken from different devices: coffee mills, heaters, even the casing - from a household appliance. The product is unique, and an attempt to repeat it can not always be crowned with success.
