Introduction to the use of video tutorials on powder pressing techniques of Delong coffee machine

Tell your friends how the correct coffee powder filling is done. In the process of pressing the powder, after evenly laying the coffee powder, the action of pressing is carried out immediately. Generally, there is an action of leveling with a slight force, and only after this action is the action of real pressure. At the end of the mild pressure, some people will have a bump on the handle to let the powder attached to the powder bowl fall into the powder bowl, and then put the handle hammer horizontally in the powder bowl and rotate clockwise three times. Then rotate counterclockwise once and lift the handle hammer so that our coffee powder is pressed.

The above mentioned rotary pressing powder is to make the coffee cake surface smooth, beginners often can not grasp the strength but the coffee cake pressure is uneven, so we can try to reduce the pressure as much as possible. try this method when you have a good grasp of the pressure.

[packing pressure] is divided into light pressure and heavy pressure. Its main purpose is to make pressed powder complete after uniform force.

①, light pressing even with the weight of the cake hammer itself.

②, heavy pressure, even if the use of artificial external forces.

Due to too much artificial force, packing is one of the biggest factors in the whole ESPRESSO extraction process, so experienced baristas choose light pressing to ensure product consistency.

The purpose of pressing powder is to ensure uniform extraction, exerting a pressure of about 30 pounds, and the gravity of the downward pressure can be measured with a single scale. It should be ensured that the strength of the powder is the same each time, and the arm is pressed vertically, so that the force applied under the powder hammer will be more uniform.

9 simple determination of the grinding thickness of coffee powder

If the coffee liquid is light and the pressed powder is not shaped, it is loose and damp, and the powder is too coarse.

If the coffee liquid is very black, dripping, not in a straight line, and there is little liquid coming out for a long time, the powder is too fine.

Normally, at first, the coffee liquid is very strong, the liquid is in a straight line, and slowly fades. Pressed powder molding is not loose and not damp.
