Bean grinding system of full-automatic coffee machine

Abstract

The invention discloses a bean grinding system of a full-automatic coffee machine, and belongs to the technical field of beverage manufacturing devices. The bean grinding system comprises a motor, a bevel gear, a lower cutter frame, a lower cutter and an upper cutter. A gear which is meshed with the bevel gear is arranged at an output end of the motor, a center shaft of the bevel gear is clamped with the lower cutter frame, the lower cutter is fixedly arranged on the lower cutter frame, the upper cutter is fixedly arranged on an upper cutter frame, and the lower cutter is coaxial with the upper cutter. The bean grinding system has the advantages that a centrifugal grinding mode is adopted, so that coffee powder ground by the bean grinding system is fine and uniform; the fineness degree of the coffee powder can be adjusted by the aid of a powder adjusting worm, so that different requirements can be met; and the system is further provided with a powder measuring device, the powder can be automatically discharged according to a set powder discharge quantity, the bean grinding system is accurate and reliable, and equipment is low in cost and compact in structure.

Description

technical field [0001] The invention belongs to the technical field of beverage preparation devices, and in particular relates to a bean grinding system for a fully automatic coffee machine. Background technique [0002] Automatic coffee machines have been more and more widely used in offices, homes, coffee shops, bars, hotels and other occasions. In the existing coffee machine, after a certain amount of coffee beans are ground into coffee powder, they are sent to the brewing device. After the coffee powder is compacted by the brewing device, the water supply device sends heated water into the brewing device, and then the Drinking coffee is directed into the cup. [0003] The grinder mechanism of the existing automatic coffee machine, such as patent No. 200720125608.2, titled "Coffee Bean Grinding System and Coffee Powder Squeezing System for Fully Automatic Coffee Machine" utility model, the motor drives the worm to rotate At the same time, the worm wheel and the lower gr...

AI Technical Summary

Problems solved by technology

When the coffee powder falls, it is easy to encounter the radial axis of the worm wheel, which will not only lose the energy of the worm wheel rotation, but also change the falling path of the coffee powder, causing the coffee powder to rise;

[0007] 3. The system uses a funnel to collect coffee powder. There is no device to measure the weight of coffee powder. The coffee machine’s powder output cannot be quantitatively output, resulting in uncontrollable coffee taste.
