Description

Interactive shearing type cutter structure for food processor

Technical field

The present invention relates to the food machinery manufacturing technology, especially a kind of interactive shearing type cutter structure for food processor.

Background technology

Food processor comprises positive displacement food processor and the on-positive displacement food processor that can pulverize foodstuff.The positive displacement food processor comprises the positive displacement food processor of soy bean milk making machine, rice paste machine, Juice machine, cooking machine, mixer and other pulverizing foodstuff.The on-positive displacement food processor comprises handheld stirring machine, desk-top mixer, vertical mixer.Its common ground of positive displacement food processor is that a staving and a reducing mechanism that holds foodstuff is arranged.Soy bean milk making machine, rice paste machine etc. also have electric heater unit simultaneously.Itself does not hold the staving of foodstuff the on-positive displacement food processor, and it only has an electronic reducing mechanism.Need stretch in other container that is contained with foodstuff, pulverize foodstuff.Since 1986, Patent Office of the People's Republic of China has announced hundreds of food processor patent application cases.Wherein, a based food processor is simple foodstuff (as meat, beans, five cereals, fruit, vegetables, solid seasoning and so on) is pulverized, and this class ordinary practice is called cooking machine, fruit juice mixer, mixer or the like; Another kind of is both foodstuff to be pulverized, and also has electrical heating (electrothermal tube, Electric radiant Heating Film, electromagnetic heater or the like) device to foodstuff heating, boiling, and this class is commonly referred to soy bean milk making machine, rice paste machine, fruits and vegetables machine or the like.Novel having concurrently pulverized and the soy bean milk making machine of heating function device, rice paste machine can also be by setting, the selections of control program: pulverize, heat merely, not only pulverize but also heat or the like function merely.

Food processor is provided with the position according to motor and is divided into: provided with motor at lower formula, motor overhead two big classes.The provided with motor at lower formula is that staving, crushing knife tool etc. is arranged on the motor top; The motor overhead is that staving (the on-positive displacement food processor does not have staving), crushing knife tool etc. are arranged on below the motor.They all relate to the foodstuff cutter structure.The effect one of cutter structure is to pulverize foodstuff; The 2nd, stirring, mixing are overturn foodstuff in container (staving), so that pulverize more thorough.Pulverizing foodstuff is by the rotation of driven by motor cutter, and effects such as cutter and foodstuff collision are pulverized foodstuff.The mixing foodstuff also is the cutter by rotation, makes the foodstuff motion when pulverizing, and reaches the mixing purpose.

The crushing knife tool of existing domestic food processor all is to adopt high-speed electric expreess locomotive to drive Disintegrating knife foodstuff is carried out the collision type pulverizing.Foodstuff such as soya bean are freely to be suspended in the water, by the edge of a knife collision foodstuff of rapid movement it are pulverized.Its crushing effect largely depends on the relative velocity between the foodstuff and the edge of a knife, and relative velocity is high more, and the collision crushing effect is good more.When cutter is crushed to particle hour (as particle diameter 0.5~2mm) with soya bean collision, the thickness of the edge of a knife is near beans material particle diameter, the edge of a knife bumps on particle, only can beat away the foodstuff particle as " playing golf ", but be difficult to (even if adopting sharp sharp tackle mouth) and further the foodstuff particle is pulverized again.Cause that the foodstuff slag is coarse, pulping rate is low, mouthfeel is poor.

Chinese patent application CN 200910070386.2 has announced the food processor that adopts the drum-type cutter structure, the edge of a knife of drum-type crushing knife tool all is in the radius of turn maximum, therefore (15% edge of a knife of only having an appointment is in the radius of turn larger part to the average linear velocity of the edge of a knife than traditional axial-flow type crushing knife tool, edge of a knife average linear velocity is low) much higher, its crushing effect relatively also promotes greatly thus.But the drum-type crushing knife tool also is that foodstuff is pulverized in collision by the edge of a knife.Therefore when the foodstuff particle is pulverized hour (for example particle diameter 0.2~0.6mm), also is difficult to be crushed to foodstuff littler again.

Disclose among CN 90208456.9 and the CN 03112424.0 and adopted moving, as to decide the abrading type reducing mechanism of bistrique soy bean milk making machine.This abrading type reducing mechanism be in essence soy bean milk making machine built-in " colloid mill ".Its defective is: move and decide necessary gapped 0.03~0.6mm between the bistrique, otherwise foodstuff liquid just can't be decided to flow through between the bistrique moving, cause and can't grind, this just makes the foodstuff particle grain size be difficult to less than this gap size again, causes actual grinding back foodstuff particle still bigger.Adopt this moving intact soya-bean milk of soymilk grinder of deciding bistrique, still have a large amount of bean dregs.Scope that these bean dregs are coarse to be exceeded " common people's comfortable taste degree ", so, adopt the soy bean milk making machine of this technology still to need configurating filtered net that bean dregs are filtered.Moving another shortcoming of deciding the abrading type reducing mechanism of bistrique formation is complex structure, cost height, and only big-and-middle-sized commercial soy bean milk making machine just adopts.Household soy milk machine also has this technology that adopts, but its price is 5~10 times of main flow soy bean milk making machine price on the market.

In addition, the crushing knife tool of collision type, the moving food processor of decide the bistrique grinding formula is because crushing effect is relatively poor, and filtering screen or outfit hand-held screen pack (bamboo strainer) separately in addition also must be set in inside.Filter screen itself cleans all pretty troublesome, uses inconvenience, has increased manufacturing cost simultaneously.

Chinese patent application CN 200910042301.X has proposed to adopt the reverse rotation simultaneously of inside and outside axle, and interior axle has crushing knife tool, and outer shaft has the soy bean milk making machine of puddle support.Its principle is that crushing knife tool leans on collision type to pulverize foodstuff, and puddle support produces flow-disturbing and has the collision pulverization simultaneously concurrently.Its defective is: be that crushing knife tool or puddle support all remain collision type and pulverize, hour (as particle diameter 0.5~2mm), collision type is pulverized and is difficult to further the foodstuff particle be pulverized again and the foodstuff collision is crushed to particle.Cause that the foodstuff slag is coarse, pulping rate is low, mouthfeel is poor.

Summary of the invention

The objective of the invention is at the deficiencies in the prior art, a kind of interactive shearing type cutter structure for food processor is provided, adopt the interactive shearing type cutter of a plurality of scissors tool designs of mutual counter motion, make the cross shear that relative motion produces between the different scissors tools that foodstuff is sheared pulverizing.Simultaneously, the scissors tool of interactive shearing type cutter structure itself has the effect of agitator concurrently.No matter the motor speed of food processor is that (for example 10000-30000 rev/min), low speed (for example 1000-3000 rev/min) can reach good crushing effect at a high speed, and structure is simple and direct, and cost is low.

A kind of interactive shearing type cutter structure for food processor provided by the invention is: interactive shearing type cutter comprises at least one first scissors tool and at least one second scissors tool, first scissors tool and second scissors tool have at least one to shear cutter hub separately, shear and have a shearing edge of a knife on the cutter hub separately at least, the edge of a knife surfaces of revolution of first scissors tool cutter hub is relative with the edge of a knife surfaces of revolution of second scissors tool cutter hub, distance 0<L≤3mm between the edge of a knife surfaces of revolution of first scissors tool cutter hub and the edge of a knife surfaces of revolution of second scissors tool cutter hub; The first scissors tool connects with the first line shaft; The second scissors tool connects with the second line shaft.First line shaft and second line shaft directly or by the motor shaft of transmission device with the food processor main body connect.

Above-mentioned transmission device can be gear drive, clutch transmission mechanism or other known transmission mechanism.

The above-mentioned food processor main body that comprises interactive shearing type cutter structure has the motor more than.

Described first or second scissors tool are detachable or non-dismountable formula settings, can be set directly at or be arranged on the line shaft by Connection Element.

First of the present invention or second scissors tool are made of cutter hub and support component, and cutter hub is arranged on the line shaft by support component.Described support component is a rigidity or flexible.

The edge of the interlaced shearing foodstuff of first, second scissors tool is the edge of a knife of scissors tool separately, and the edge of a knife is rectilinear form, curve shape, zigzag fashion or broken line shape.

The edge of a knife of first or second scissors tool cutter hub is dull edge or sharp tackle mouth.Distance between the edge of a knife surfaces of revolution of the edge of a knife surfaces of revolution of described first scissors tool cutter hub and second scissors tool cutter hub equates everywhere, when for example main first cutter cutter hub overlaps with second scissors tool cutter hub (angle theta is zero between two cutter hubs), the distance between the edge of a knife is 0.01mm all.

Distance between the edge of a knife surfaces of revolution of first, second scissors tool cutter hub is unequal everywhere.For example distance is 0.01mm between the edge of a knife of first scissors tool cutter hub radius of turn 15mm place's edge of a knife and second scissors tool cutter hub; Distance is 1mm between the edge of a knife of first scissors tool cutter hub radius of turn 25mm place's edge of a knife and second scissors tool cutter hub.

The cutter hub of first or second scissors tool is rigidity, flexibility or flexible.

Described first or second scissors tool are to be arranged on the line shaft by flexible support members (for example spring).In the time of the interlaced shearing of first, second scissors tool foodstuff really up to the mark, the flexible support members distortion makes foodstuff really up to the mark break away from the edge of a knife of mutual interlock, avoids (being in rotation status) first or second scissors tool stuck by foodstuff really up to the mark.

Working hole on first or the second scissors tool, the single hole area of pod apertures size are that hole shape is any arbitrarily.Hole (area) size preferably can be by whole grain soya bean (average diameter about 5~6mm).

Distance L between the edge of a knife surfaces of revolution of first, second scissors tool cutter hub is more little, and then the shearing pulverizing is thin more, otherwise then shears the particle diameter big more (promptly coarse) after pulverizing.When between the two the distance greater than the foodstuff particle diameter (as beans.The average grain diameter of soya bean general 5~6mm), in the time of as 12mm, (for five cereals such as common soya bean, red bean, mung bean, rice) then lose shearing effect (because distance is greater than the soya bean particle diameter between the edge of a knife surfaces of revolution of first, second scissors tool cutter hub, can't clip soya bean), become only is to pulverize foodstuff (but this moment for the bulky grain foodstuff, still have the shearing pulverization greater than the haw of 12mm as diameter) by first, second scissors tool cutter hub collision.So for the cutter structure that has first, second scissors tool equally, the difference of L numerical value, this cutter is pulverized the principle difference of foodstuff, effect (grain fineness) difference that pulverizing can reach.The L value is that collision type is pulverized greater than the foodstuff average diameter of particles time; The L value is shearing pulverizing less than the foodstuff average diameter of particles time.

And collision type is pulverized, when the thickness of the edge of a knife through near beans material particle diameter the time, the edge of a knife bumps on particle, is difficult to further the foodstuff particle be pulverized again.Cause that the foodstuff slag is coarse, pulping rate is low, mouthfeel is poor.The L value even if first, second scissors tool rotates in the opposite direction, only is the speed of related movement that has been equivalent to increase between the edge of a knife and the foodstuff also greater than the foodstuff particle diameter time, has slight lifting crushing effect effect, pulverizes but remain collision in essence.The L value then becomes shearing pulverizing less than the foodstuff particle diameter time, shears the opposite cross shear of direction of generation mutually by the oral sex of first, second scissors, with foodstuff staggered shear to open (shear that to pulverize must be that first, second scissors mouth acts on foodstuff particle both sides simultaneously; Just edge of a knife collision foodstuff is pulverized in collision), the L value near 0mm the time shearing pulverizing foodstuff can be crushed to " molecule that people's tongue can not differentiated " and just reach " mouthfeel does not have slag ".The particularly important is: each crushing process that collision type is pulverized is " the single edge of a knife is beaten on the foodstuff particle, and it is smashed ", requires the edge of a knife average linear velocity must be more than 15 meter per seconds.Corresponding rotating speeds will reach (the axial-flow type cutter typical radius 25mm of existing soy bean milk making machine, the about 15mm of edge of a knife average radius of gyration) more than 10000 rev/mins at least.If 3000 rev/mins slowspeed machine drives the collision type crushing knife tool, then 5 meter per seconds because edge of a knife average linear velocity is only had an appointment can't be realized even very coarse pulverizing at all.(though edge of a knife linear velocity height can increase the number of times of shearing in the unit interval) pulverized and not required then that edge of a knife linear velocity must be high to interactive shearing type, even if slowspeed machine (1000~3000 rev/mins) driving also can realize meticulous pulverizing.Adopting another benefit of slowspeed machine is that noise can reduce significantly.

The difficult point of crushing knife tool technology is a large amount of granule foodstuffs (further is crushed to littler (because be crushed to particle diameter 0.5~2mm for bulky grain foodstuff such as whole grain soya bean, careless any crushing knife tool can both be accomplished) as particle diameter 0.5~2mm).And distance L is the key technology of this cutter structure crushing effect of decision between the edge of a knife surfaces of revolution of first, second scissors tool cutter hub.About 5~the 6mm of average grain diameter of whole grain soya bean when L value is 4~5mm, though first, second scissors tool can be sheared the soya bean of whole grain alternately, works as beans material particle diameter and is crushed to less than this L value and (promptly less than 4~5mm) time, just can't further shears pulverizing.Therefore the L value is limited to below the 3mm, has substantial technological break-through.

Described first or second line shaft are unidirectional rotation or two-way (rotating) rotation.Unidirectional rotation is to rotate clockwise or counterclockwise; Two-way (rotating) rotation is that the certain angle (as 180 °) that turns clockwise oppositely is rotated counterclockwise certain angle again.

Described first or second scissors tool are provided with guide shell.
