Abstract

The invention discloses an efficient mixing knife, which belongs to the technical field of food mixing machines, and aims at overcoming the defects that the blade of the existing food stirring machine has lower hit rate of materials and cannot smash the materials into the preset fineness within a shorter time. The efficient mixing knife comprises a rotating shaft, clamp nuts and spring pads, wherein an upper blade, a middle blade and a lower blade are assembled on the rotating shaft, and have cutting edges which are respectively arranged at the two sides, and are separated by gaskets; and inclined planes which are started from the knife edge to the knife back are respectively arranged at the two sides below the upper blade, the inclined planes which are started from the knife edge to the knife back are respectively arranged at the two sides above the lower blade, and the cutting edges of the middle blade are arranged on a plane which is connected with the knife backs of the upper and lower blades. The efficient mixing blade is applicable to the food mixing machine.

Description

Efficient stirring blade

Technical field

The present invention relates to a kind of food blending machine technology, particularly relate to a kind of efficient stirring blade.

Background technology

In a lot of food processing enterprises, in order to manufacture some like pulp, vegetable puree, fish, meat gruel, food such as filling material all will use food blending machine, carry out to raw material pulverizing, stir, process operation such as grinding.Present food blending machine mainly leans on the high speed rotation of blade, under the effect of current, hits material repeatedly, smashes material.Owing to be loaded on now on the main shaft that food blending machine rotates at a high speed, generally have only a slice blade.In operation process, to material to hit rate lower, can't within a short period of time, be crushed to material the fineness of setting efficiently.In order to reach technological requirement, the operator must adopt the working system that prolongs mixing time, has not only reduced operating efficiency, many consuming electric powers; More disadvantageously be that because material is in the stirring of long period, temperature raises and sneaks into too much air, makes the color and luster of finished product become ugly, the oxidized destruction of nutrition.Also some enterprise handles material with colloid mill or homogenizer after mixer tentatively stirs again; Do like this,, increased equipment investment, and in the process of material, increase operations such as a lot of input and output materials, transportation, cleaning, processing cost is significantly increased though the quality of finished product has had raising.

Summary of the invention

The purpose of this invention is to provide a kind of efficient stirring blade, the blade that overcomes present food blending machine be provided with to material to hit rate lower, can't within a short period of time, be crushed to the deficiency of setting fineness to material efficiently.

The present invention is achieved through following technical proposals.

The present invention includes rotating shaft, clamp nut, spring pad, cutter, middle blade and bottom knife that cutting edge sets up both sides separately are housed in said rotating shaft, separate by pad between them; Below said cutter, establish the inclined-plane that starts from blade to the knife back on two limits respectively, above said bottom knife, establish the inclined-plane that starts from blade to the knife back on two limits respectively, the cutting edge of said middle blade is located on the plane that the back side connected of bottom knife.The set of blades that remarkable improvement of the present invention is made up of said cutter, middle blade and bottom knife; Not only serve as task separately as blade chopping material; And between said cutter and said bottom knife; Because knife face is provided with the inclined-plane that starts from blade to the knife back, forms a capture passage that the roomy outlet of the import in face of streams is narrow.In stirring, make streams obtain compression and speed-raising at this capture passage, then by blade chopping in said, said middle blade is improved greatly to the rate of hitting of material, the chopping effect is better.Simultaneously, streams receives effects such as fluid power shearing, the extruding of knife face, intergranular strong bump, decompression expansion capturing in the process of passage through this, makes material rapid refinement and mixing each other more uniformly.The cutting edge present position of blade is extremely important in said, and according to actual measurement, when cutting edge just was in the plane that the back side connected of bottom knife, most effective, effect was best.Be extruded the strongest place because this position is a streams, after said middle blade shredded the particle in the streams, particle also can and receive the knife face friction to continue refinement because of the decompression expansion.

In order to make the space between the blade of said upper, middle and lower; Can because of the difference of the material composition that will blend adjust, said pad has two kinds of thickness at least, for said cutter, middle blade, bottom knife; Their spacing distances each other can be adjusted by the said pad of different-thickness.The present invention is provided with the inclined-plane that starts from blade to the knife back below said bottom knife; This inclined-plane role; It is the streams of disturbance mixer container bottom; Make its quickly with container in unclassified stores stream mix, reduce intergranular granularity and density contrast in the streams, make the even tissue of finished product.

Against existing technologies, the invention has the beneficial effects as follows:

Can shorten the time of stirring operation, help energy-conservation and prevent that material from heating up too high and oxidation stain; Improve the fineness and the mixed uniformity of finished product, optimize product quality.

Description of drawings

Fig. 1 is a structural representation of the present invention, Fig. 2 be the A of Fig. 1 to view, Fig. 3 is the I of Fig. 2---I cut-away view, Fig. 4 are the II of Fig. 2---II cut-away view.Among the figure: 1, rotating shaft, 2, clamp nut, 3, spring pad, 4, cutter, 5, middle blade, 6, bottom knife, 7, pad.

The specific embodiment

Below in conjunction with the accompanying drawing and the specific embodiment the present invention is done further description.

Shown in accompanying drawing, can be well understood to the structure of the embodiment of the invention, can find out that from Fig. 3 and Fig. 4 the streams passage that is narrowed gradually by top of forming of the following and bottom knife 6 of cutter 4 is in face of being cut the streams of hitting.Cutter 4, middle blade 5, bottom knife 6 are being installed on 1 last time of rotating shaft, and the spacing between them can be adjusted with the pad with multiple thickness 7, has put spring pad 3 at last, tightens clamp nut 2.In whipping process; The set of blades of rotating shaft 1 drive lower end is rotated at a high speed; Material at first by the cutting edge chopping of cutter 4 and bottom knife 6, simultaneously, has a large amount of materials to be captured by the gradually narrow passage between last bottom knife with current; Streams by powerful extruding, receives between fluid power shearings, knife face friction, particle multiple destructive power such as mutual bump in passage; When flow pass, self decompression expansion is gone back in the high-speed cutting of blade 5 in receiving simultaneously, forms local cavitation effect at last, makes material rapid refinement and mixing each other more equably.

Claims
