Low-noise high-efficiency food processing machine

Abstract

The invention relates to a low-noise high-efficiency food processing machine, which comprises a machine base and a stirring cup, wherein a motor is arranged in the machine base; the stirring cup comprises a cup body and a crushing knife; the crushing knife comprises a crushing blade and a knife shaft; the crushing blade is positioned in a cup body; the knife shaft penetrates through the cup body and is driven to rotate by a motor; the crushing blade comprises a wing root and a blade wing; the blade wing comprises a crushing wing and an extension wing positioned at the tail end of the crushingwing; the extension wing extends backwards along the rotation direction of the blade wing; a cutting edge is formed on the outer side of the blade wing blade; a cutting point is formed on the tail endof the extension wing; and the radius from at least one point in the middle of cutting edge to the center of the wing root is the maximum radius from the cutting edge to the center of the wing root,and the radius from the cutting point to the center of the wing root is no larger than the maximum radius.. According to the machine, the extension wing is arranged, the space formed by the crushing wing can be occupied after the crushing blade performs cutting and rotating, so that the crushing blade is prevented from generating vortex, the kinetic energy release of food materials after being through the crushing blade is relieved, the noise pollution caused by the vortex generation is reduced, and at the same time, the crushing performance is improved.

Description

technical field [0001] The invention relates to the field of food processing, in particular to a food processing machine which relies on motor-driven blades to realize crushing. Background technique [0002] Existing food processing machines usually include a machine base and a stirring cup arranged on the machine base. A motor is arranged in the machine base. The stirring cup includes a cup body and a pulverizing knife, and the pulverizing knife includes a pulverizing blade. Rely on the motor to drive the pulverizer to rotate in the mixing cup to cut and crush the ingredients, so as to realize the processing of the ingredients. Especially like the existing wall breaking machine, the speed of the crushing knife is above 15000rpm, so as to achieve the purpose of breaking the wall of the food material. [0003] However, this kind of processing method usually has the following problems: since the food processing machine relies on the high-speed rotation of the motor to achieve...

Problems solved by technology

[0003] However, this kind of processing method usually has the following problems: since the food processing machine relies on the high-speed rotation of the motor to achieve processing, the motor will inevitably bring vibration and processing noise to the whole machine, although the existing products have adopted soft connections and other methods to solve the noise To reduce the noise of the whole machine, but there is still no good solution to the noise in the mixing cup, especially the impact between the pulverizer and the food, and the movement of the food itself when the pulverizer drives the food to rotate at a high speed.

There are also some technologies that use methods such as reducing the speed to reduce noise, but this in turn brings about a significant reduction in crushing performance and crushing efficiency.

In another solution, the crushing performance of the crushing blade is changed by increasing the contact area between the crushing blade and the food material or increasing the turbulence effect of the crushing blade by bending the crushing blade, but such a change will bring noise increase

In the prior art, there is no better technical solution to simultaneously solve noise and crushing efficiency
