An impact type constant pressure coffee tamper

Abstract

The invention relates to a coffee tamper, in particular to an impact type constant pressure coffee tamper which comprises a handle and an impact constant pressure mechanism. The impact constant pressure mechanism comprises a pressure drum, a pressure block, a sliding block, a sliding sleeve and a center. The sliding block is provided with a sliding block spring, the center is provided with a center spring, one end of the pressure drum is connected with the handle, the other end of the pressure drum is connected with the sliding sleeve, the sliding sleeve is connected with the pressure block, the sliding block is arranged in the pressure drum, and the center is fixed to the pressure block through the center spring. The impact type constant pressure coffee tamper is simple in structure and reasonable in design, achieves a constant-pressure labor-saving effect and guarantees uniformity in powder pressing.

Description

technical field [0001] The invention relates to a coffee tamp, in particular to an impact type constant pressure coffee tamp. Background technique [0002] At present, brewing a cup of mellow coffee generally includes the following steps: firstly, the coffee beans are ground into powder by a bean grinder, then the powder is poured into a powder bowl, and then the powder is flattened with a powder tamper matching the powder bowl, Finally, it is brewed into coffee by a coffee machine, which is convenient for people to drink. [0003] In the coffee making process, grinding and brewing are basically automated and controlled by numerical control, only the step of flattening the powder still has to be handled manually. As for the manual tamping process, whether it is a novice or an experienced barista, it will be troubled by it. This is because the traditional tamping process not only tends to skew the tamping surface when the handle is pressed down, but also The operation force...

As for the manual tamping process, whether it is a novice or an experienced barista, it will be troubled by it. This is because the traditional tamping process not only tends to skew the tamping surface when the handle is pressed down, but also The operation force of the powder cannot guarantee a constant pressure every time, because the pressure of the powder pressing will be different every time, which makes the uniformity of the coffee powder different, and the uniform coffee powder determines whether a cup of coffee is delicious or not One of the important factors is that if the particle density of the coffee powder is loose, it is easy to brew a sour or light coffee; if the particle density of the coffee powder is too dense, it is easy to brew a bitter or burnt coffee. coffee

[0004] Aiming at the problem that the traditional tamp cannot guarantee the constant pressure on the tamping working surface, there are two so-called "constant pressure tamps" on the market, the first one is a limited stroke type tamp, This type of tamper achieves a constant pressure by adjusting the depth of pressing into the powder bowl. In fact, if the amount of powder cannot be determined consistently, the predetermined pressure cannot be guaranteed. Strictly speaking, this type of tamper can only be called a fixed-stroke tamper. The limit mechanism is not follow-up, and the level cannot be guaranteed during the pressing process of the powder tamper, and it will only be level when the pressing is terminated, which loses the opportunity to adjust the uneven distribution of powder when pressing down

The second type is the spring pressure constant pressure powder compactor. This kind of powder compactor realizes constant force by compressing the built-in single spring until the handle collides with the bottom. During operation, the handle can be judged to be "pressed to the bottom" by the user's hand feeling. If the user If you continue to press when you feel the bottom, you will increase the pressure. If you stop when you don’t reach the bottom, you will reduce the pressure. All the pressure acting on the powder is static pressure, and the operation is more laborious.

[0005] In fact, only a tamper with the above two functions can be called a tamper with constant pressure, and there is no tamper with the above two functions in the market.
