Coffee tamper

Abstract

The present invention provides a coffee tamper, comprising a casing. A driving device is arranged on the inner top of the casing, connected to a tamping device and used to drive the tamping device topress down and move up. The tamping device is used to press down a container filled with coffee powder and comprises a main shaft, the driving device is connected to the upper end of the main shaft, and a tamping head is connected to the lower end of the main shaft and can be pressed into the container; and in one of embodiments, a container pressing head is sleeved on outside of the tamping headand has an outer cover sleeved on outside of the tamping head, the lower edge of the outer cover is located on the same horizontal plane and presses against the upper edge of the container, and the tamping head can move up and down relative to the container pressing head. The present invention provides a novel coffee tamper, which can overcome defects of existing equipment, apply uniform pressureon coffee powder and make flat coffee powder.

Description

technical field [0001] The present invention relates to an automatic coffee tamper. Background technique [0002] When brewing coffee, pressing coffee powder is a step of brewing coffee. It is necessary to press the ground coffee powder before brewing coffee, which has a considerable impact on the taste of the brewed coffee. Pressing coffee powder today generally relies on manual and mechanical automatic methods. [0003] The existing method of pressing coffee powder mainly has the following defects. [0004] Manually pressing coffee powder may cause hand fatigue or even injury, and the efficiency is not high. However, some manual tamping machines on the market use rack drive, which can reduce fatigue, but still cannot solve the problem in essence, and there is no rotating action, resulting in unsatisfactory tamping effect. [0005] There are also some mechanized automatic powder tamping machines on the market, but the pressure of powder tamping is to output the downforce...

AI Technical Summary

Problems solved by technology

[0004] Pressing coffee powder manually may cause hand fatigue or even injury, and the efficiency is not high

However, some manual tamping machines on the market use rack drive, although it can reduce fatigue, but it still cannot solve the problem in essence, and it does not rotate, resulting in unsatisfactory tamping effect

[0005] There are also some mechanized automatic powder tamping machines on the market, but the pressure of powder tamping is to output the downforce of the motor by calculating the current. There is an error in the power transmission, for example, because the container (portafilter) is not placed horizontally, which affects the pressure of the coffee powder when it is actually pressed, and finally results in an unsatisfactory tamping effect

[0006]Further, in order to ensure that the pressed coffee powder is evenly stressed, the coffee powder is generally pressed multiple times. For some coffee powders that can be pressed multiple times Powder tamping machines (whether with or without rotating action), the coffee powder may be pressed to exceed the required pressure value after repeated tamping

[0007] After the above-mentioned equipment fills the coffee powder into the container (portafilter), the coffee powder will generally appear in the shape of a small hill, and the barista needs to put the coffee powder before pressing the powder The small hills are leveled by hand or tools so that the coffee powder can be evenly pressed. Existing equipment cannot realize the mechanization and automation of this step.

[0008]In summary, in the existing coffee powder pressing methods, whether manual or automatic, there is still room for improvement
