Description

Stirring knife assembly and cooking machine

Technical Field

The utility model relates to the field of food processing, in particular to a stirring knife assembly and a cooking machine.

Background

With the increasing level of living of people, many different types of food processing machines appear on the market. The functions of the food processor mainly include, but are not limited to, the functions of beating soybean milk, squeezing juice, mincing meat stuffing, shaving ice, making coffee, and/or preparing facial masks. A food processor, such as a meat grinder, comprises a food material container, a container cover covered on the food material container, a stirring knife assembly positioned in the food material container and a host machine arranged on the container cover. When the food processor works, the main machine drives the stirring knife assembly to rotate in the food material container, so that the food material is crushed. However, the existing food processor has the problem of uneven crushed food materials.
