Grinding brewing slag discharging device of coffee machine

Abstract

The invention provides a grinding brewing slag discharging device of a coffee machine. The grinding brewing slag discharging device of the coffee machine comprises a bottom plate, a grinding device and a brewing slag discharging device, wherein the brewing slag discharging device is arranged at the middle part of the bottom plate; and the grinding device is arranged at the end part of the brewingslag discharging device. The grinding brewing slag discharging device provided by the invention has the beneficial effects that disc-shaped horizontal cutter blades in orderly arrangement are adoptedinside the grinding device, so that coffee beans are finely and uniformly ground; a height regulating device is arranged above the grinding device, so that the fineness degree of coffee powder is adjustable; during coffee brewing, pistons move in front and back, so that the coffee powder and hot water are better blended; brewing is sufficient; and the mouthfeel is better; the structure is novel; the performance is reliable; two model elements are creatively combined to form a work cavity capable of being used for coffee brewing, and after separation, slag is pushed out under the action of thepistons, and slag discharging is convenient; and the grinding brewing slag discharging device is worthy of being popularized.

Description

technical field [0001] The invention belongs to the technical field of coffee machines, and in particular relates to a grinding, brewing and slag-discharging device of a coffee machine. Background technique [0002] With the improvement of China's internationalization, Chinese people have gradually accepted the entry of coffee, and its unique fragrance has been loved by many people in the city. In recent years, tasting good coffee has even become a sign of good taste. There are many ways to prepare coffee beverages. There are canned coffee beverages for direct drinking and powdered instant coffee brewing packets. However, the surface of pre-ground coffee powder will be rapidly oxidized due to the large contact surface with the air. Over time, it will produce a sour taste due to the detachment of the fat contained in the coffee powder. Therefore to prepare a cup of delicious coffee, it still needs to be ground and brewed now; although the existing coffee machines have many ...

AI Technical Summary

Problems solved by technology

[0003] 1. The thickness of the coffee powder is fixed: the gap of the internal grinding mechanism of the grinder is a fixed size, and the size of the ground coffee powder is the same; but after a period of use, the grinding mechanism will cause the gap to become larger due to wear. The ground particles of the ground coffee powder will also become relatively larger, which will affect its quality

[0004] 2. The taste of brewing is not good: the factors that affect the taste are the following: water temperature, coffee powder fineness, the ratio of coffee powder to water and whether it is well mixed. The ideal water temperature for brewing coffee powder is between 90-95 ℃. If the water temperature is too high and the coffee is over-extracted, the coffee will become bitter and spicy; if the water temperature is too low, the coffee will be sour if the coffee is not extracted enough; and the coffee brewed in the current coffee machine is basically not fully mixed, which seriously affects the taste.

[0005] 3. After the freshly ground coffee powder is not fully mixed after brewing, a large amount of residue will be produced, which will reduce the utilization rate of coffee beans. At the same time, if the residue remains in the coffee machine, it will pose a threat to health; however, the device for removing residue The structure is complex, some require frequent replacement of filter paper, the operation is cumbersome, the cleaning and maintenance of the equipment will take a lot of time, and the overall efficiency is low
