Description

Labor-saving constant-pressure coffee powder pressing device

Technical Field

The utility model relates to a coffee powder pressing device technical field especially relates to a coffee powder pressing device of laborsaving level pressure.

Background

Currently, brewing a cup of mellow coffee generally comprises the following steps: firstly, grinding coffee beans into powder by a bean grinding machine, then pouring the powder into a powder bowl, flattening the powder by a powder pressing device matched with the powder bowl, and finally brewing the coffee into coffee by a coffee machine, thereby being convenient for people to drink.

In the coffee production process, grinding and brewing are essentially automated and operated by numerical control, only the step of pressing the powder still being handled manually.

The powder pressing is an important step in the preparation process of Espresso (Espresso), and the specific process is that ground coffee powder is put into a brewing handle, the coffee powder is pressed flat by a coffee powder pressing device to form a flat and solid horizontal plane, and then the brewing handle is arranged on a coffee machine to extract the coffee powder.

The step of manual powder pressing is troubled by both novices and experienced coffeemakers, because the working face of the powder pressing is easy to deflect in the process that a handle of a traditional powder pressing device presses downwards, the operation force of the powder pressing cannot guarantee that the pressure is constant every time, the uniformity of the coffee powder is different because the pressure of the powder pressing is different every time, the uniform coffee powder is one of important factors for determining the delicacy of a cup of coffee, and if the particle density of the coffee powder is loose, the coffee powder can be easily brewed into coffee with sour or light taste; if the coffee powder has too dense a particle density, it will tend to brew coffee with a bitter or burnt taste.

Aiming at the problem that the traditional powder pressing device can not ensure that the powder pressing working face is subjected to constant pressure, two types of constant-pressure powder pressing devices are available on the market. The first is a limited stroke type of powder press which achieves a constant pressure by adjusting the depth of pressing into the powder bowl, and in fact, if the powder amount is not certain to be consistent, a predetermined pressure cannot be guaranteed, and the feedback pressure is not from the surface of the coffee powder and cannot give a definite force feedback. Strictly speaking, such powder presses are only called fixed stroke powder presses. The second kind is spring pressure presses powder ware surely, and this kind of powder ware realizes the constant force through the handle and bottom collision of built-in single spring compression, judges handle "pressing to the end" through user's feeling impression during the operation, if the user still continues to press when feeling to the end, will increase pressure, if stop when not reaching to the end, will reduce pressure, receives the human interference factor very big and comparatively difficultly during the operation.

In fact, the two kinds of powder compactors do not calculate constant pressure, and only the powder compactor which takes the pressure acting on the surface of the coffee powder as the set pressure and is not limited by the powder quantity in the powder compacting process and is not interfered by human factors after the preset pressure is finally reached can be called as the constant pressure powder compactor.
