Milk foaming device capable of automatically producing foamed milk

Abstract

The invention relates to a milk foaming device capable of automatically producing foamed milk. The milk foaming device comprises a casing with a cavity, wherein an outlet is formed in the bottom of the casing, and a steam supply channel, a milk supply channel and an air inlet channel are formed in the lateral portion of the casing. The milk foaming device is characterized in that a partition wall is formed in the casing, a rotary mixing region is formed in the cavity by means of partition of the partition wall, and steam, milk and air can be mixed in the rotary mixing region in a rotary flowing mode. An injection port is formed in the lateral wall of the casing and communicated with the outlet through the rotary mixing region, and the steam supply channel, the milk supply channel and the air inlet channel are communicated with the rotary mixing region through the injection port. Mixture of the steam, the milk and the air can be ejected out of the injection port, enters the rotary mixing region formed by the partition wall at a high speed under push of inertia and follow-up steam, and rotates for multiple circles in the rotary mixing region. The steam, the milk and the air are further mixed fully and uniformly in the rotary mixing region during rotation of the mixture.

Description

technical field [0001] The present invention relates to a milk frothing device for preparing steam milk froth, in particular to a milk frothing device for automatically producing frothed milk, which can be used together with or integrated into a coffee machine. Background technique [0002] When drinking coffee, adding silky and delicate milk foam in the coffee can increase the taste and texture of the coffee, and can play a very good decorative role. The milk foam is the product of the fine mixing of milk and air. Devices for producing frothed milk have various structural forms. [0003] One of them is a device that generates frothed milk by rapidly stirring milk, which generally includes a heating device, a base, a container body and a container cover arranged on the base, and the heating device is generally arranged in an accommodating cavity at the bottom of the base. The container body and the base can be separated. There is also a stirring head in the container body. ...

AI Technical Summary

Problems solved by technology

However, since the steam inlet and the milk inlet are independent of each other, and the steam inlet is directly facing the outlet of the vacuum chamber, the steam is not fully mixed with the milk and air in the vacuum chamber, and it quickly flows out through the outlet of the mixing chamber, that is, steam The mixture of steam, milk and air enters the emulsification chamber through the outlet of the mixing chamber according to their respective speeds and angles, and the residence time of the steam, milk and air in the vacuum chamber is extremely short, resulting in this foamer steam, milk and air three The time of mixing with each other is short, so the milk foam produced is not delicate enough, and the taste is poor
