Reciprocal rotary knife type material processor

Abstract

The invention relates to a reciprocal rotary knife type material processor which is an improvement on a machining unit of kitchen appliances that make food of slurry, juice and paste and the like. The reciprocal rotary knife type material processor has universal working principle and can be arranged on various food processor at current to work or can be used similarly in other fields. The primary working part of the processor uses two concentrically reversed cutter shafts which are fixed with rotary cutters for machining. The machining rotary cutters can rotate at high speed positively and reversely under drive of a motor and transmission machinery, thereby overcoming the deficiency that the materials generate eddy to reduce the machining efficiency when the unidirectional rotary cutter works at high speed. The double-edged cutters have better machining effect in two rotary directions. The layered cutters and curved cutters can increase the working space. The invention solves the problems of the driving mode of dual-cutter shafts, the shape of the rotary cutters and improves the grinding effect and the like.

Description

Technical field: [0001] The present invention relates to kitchen utensils, specifically a multi-purpose processing machine that can be used to make pulp, juice, paste or crush and grind various foods, and mainly aims at the design of its mechanical part. technical background: [0002] Existing commonly used household automatic food processors, in order to realize the crushing of food materials, adopt the principle of unidirectional rotation and crushing by a high-speed motor to drive a single-axis cutter. Its rotary knife strikes and collides the materials in the filter screen to achieve the crushing effect. The main disadvantages of this structure are high working noise, low pulping rate, and the pulverized particles are not fine enough. Although various food processors or soybean milk machines in the past have adopted the two-step processing technology of coarse crushing and fine grinding, because the traditional single rotary knife is usually used in the coarse crushing ...

AI Technical Summary

Problems solved by technology

The main disadvantages of this structure are high working noise, low pulping rate, and the pulverized particles are not fine enough.

Although various food processors or soybean milk machines in the past have adopted the two-step processing technology of coarse crushing and fine grinding, because the traditional single rotary knife is usually used in the coarse crushing part, the material will form a vortex when rotating at a high speed. Although this phenomenon can be alleviated by various forms of spoiler rings, some materials will still break away from the impact of the rotary knife, and the problem of reduced crushing efficiency has not been fundamentally solved.

The principle design of the existing fine grinding mechanism is not reasonable enough, because the impact velocity and force of the juice in the grinder are not large enough, so that the fine grinding effect of the juice is not obvious during work
