The application is based on soya-bean milk industry experience for many years of inventor and the discovery of following technical problem and understanding is made:
The manufacturing soya-bean milk of existing soy bean milk making machine first heats pulping raw material, pulverizes then infusion of bean or pea again, prevents that soya-bean milk is sticking and soya-bean milk foam overflow, but also caused thus soymilk concentration low when wherein the object of heating is infusion.
Applicant finds, in order to improve soymilk concentration, must before heating pulping raw material, pulverize bean or pea, first make raw soya-bean milk, and then heat infusion and obtain ripe soya-bean milk, thereby the starting stage of preparing at soya-bean milk is improved soymilk concentration, and keep soya-bean milk original flavor, then by improving the process of soya-bean milk infusion, realize the very big minimizing being sticking and eliminate in traditional handicraft the too much technical problem of foam in raw soya-bean milk infusion process, and adopt process of the present invention the concentration of the soya-bean milk of preparation can be brought up to 6.0g/100mL, even be greater than 6.0g/100mL, far above existing industry standard.In addition, by process of the present invention and equipment, can realize for example life-time dilatation of the driving arrangement of motor, thereby reduce the maintenance cost of soy bean milk making machine.
To the technology and equipment for the preparation of soya-bean milk according to the present invention be elaborated below.
Method for the preparation of soya-bean milk of the present invention can adopt soy bean milk making machine, and as depicted in figs. 1 and 2, this soy bean milk making machine can comprise staving 101, grinder 103, heater 107, agitator 109, controller (scheming not shown).But it should be noted that, the invention is not restricted to the soy bean milk making machine in Fig. 1, for the soy bean milk making machine of other types, for example heater 107 is arranged on outside staving 101 sidewalls or is arranged on the soy bean milk making machine in staving 101, all can adopt preparation method of soymilk of the present invention to prepare soya-bean milk.
As depicted in figs. 1 and 2, grinder 103 is arranged in staving 101, and grinder 103 can drive it to rotate to pulverize the pulping materials being contained in staving 101 by pulverizing motor 105, to obtain slurrying liquid.Agitator 109 is arranged in staving 101, and agitator 109 drives it to rotate so that slurrying liquid is stirred by stirring motor 111.
Be appreciated that grinder 103 and agitator 109 can be same parts, as shown in Figure 1, now stirring motor 111 is also same parts with pulverizing motor 105, and grinder 103 had both possessed crushing function, also had agitating function simultaneously.Certainly, be understandable that equally, as shown in Figure 2, agitator 109 and stirring motor 111 also can be respectively two independent parts.
As depicted in figs. 1 and 2, heater 107 for example, for the pulping materials in staving 101 or slurrying liquid (raw soya-bean milk) heating, heater 107 can be heating tube, can certainly be heating plate or any device that can heat the slurrying liquid holding in staving.Controller can be connected for controlling these component workings with heater 107 with pulverizing motor 105, stirring motor 111 respectively.
Inventor is surprised to find that in to soya-bean milk technique years of researches process processed, mixing speed is sticking the tangible relevance of degree when whether the slurrying liquid of for example raw soya-bean milk is sticking or is sticking phenomenon, inventor further finds, mixing speed is not as higher in the agitation speed generally believing in industry better to preventing the effect being sticking.On this basis, inventor has proceeded great many of experiments and research discovery, cancel heating process, directly pulping materials is carried out to pulverization process, then adopt low rate mixing and heat infusion, not only can obtain higher concentration of slurry, can also effectively improve and be sticking the generation that phenomenon even avoids being sticking phenomenon simultaneously.
3 pairs of preparation method of soymilk of the present invention are described in detail below with reference to accompanying drawings.The method of preparing according to an embodiment of the invention soya-bean milk, comprises the following steps:
The pulping materials being contained in the staving 101 of soy bean milk making machine is directly pulverized, to obtain raw soya-bean milk (S1).The pulping materials that the interior direct pulverizing of staving 101 obtains, not through heating, is pulverized with heating the pulping materials obtaining and is compared, in the situation that identical beans liquor ratio has higher soymilk concentration.It should be noted that, this raw soya-bean milk also can directly provide from outside, to carry out following step S2(, will be described in detail below).
Then, the raw soya-bean milk being contained in staving 101 is heated to infusion (S2).
Wherein raw soya-bean milk is being heated in the process of infusion, raw soya-bean milk is stirred, the speed stirring is 1000rpm~3000rpm, inventor surprisingly finds that through test of many times mixing speed can affect the generation that is charred phenomenon, therefore, inventor by further research mixing speed on the impact that whether can produce the degree that is charred and is charred in heating infusion process, the speed not found is higher better to telling on of preventing from being charred, therefore inventor is summed up and is drawn by test of many times: while adopting above-mentioned mixing speed to stir raw soya-bean milk when heating infusion, can effectively avoid the generation that is charred.
The method of preparing according to an embodiment of the invention soya-bean milk, cancelled and in advance pulping materials has been carried out to pre-heated step in traditional preparation technology, first directly the raw soya-bean milk in soymilk machine barrel body 101 is heated to infusion, be about to pulverising step preposition, can obtain the raw soya-bean milk that concentration is higher like this, simultaneously, comparing traditional preparation technology can save the heat time, effectively shorten mixing time, and, by adopting predetermined speed to stir to raw soya-bean milk infusion process, can avoid the generation that is sticking phenomenon and overfoaming phenomenon in soya-bean milk process processed.Due to the cause of the Speed Reduction stirring when stirring, the life-span of stirring motor is also extended simultaneously.
According to one embodiment of present invention, can control pulverizing motor 105 with 103 rotations of First Speed V1 driving grinder by setting controller, First Speed V1 is not more than the rated speed V0 that pulverizes motor; And agitator 109 is in heating infusion process, controller is controlled the speed V2 that stirring motor 109 drives 105 pairs of raw soya-bean milks of agitators to stir and is less than First Speed V1.
In the above embodiment of the present invention, the raw soya-bean milk being contained in staving 101 can directly stir by being vertically arranged on the interior grinder of staving 101.In this embodiment, grinder is not covered with flow spoiler or filter screen (for example daraf(reciprocal of farad) net) around.
Because finding mixing speed, inventor is not the bigger the better, therefore on this basis, inventor has carried out lot of experiments, the speed V2 for example stirring is made as: 1000rpm, 1500rpm, 2000rpm, 2500rpm, 3000rpm inventor are surprised to find, being sticking phenomenon is further improved, slurries foam also reduces greatly, can facilitate for example the carrying out of follow-up de-foaming process like this, reduces froth breaking difficulty.
For example, in this embodiment, pulverize the rated speed V0=12000 rev/min of motor 105, speed V2≤3000 rev/min, are no more than 3000 revs/min by controlling the output speed of stirring motor 111, and infusion process is sticking degree very gently or disappears.
In this embodiment, the speed of stirring motor 111 can be controlled at 1300-2500 rev/min.Obtain thus the good effect not being sticking.In addition, because the rotating speed of motor is reduced to the over half of traditional rotating speed, thereby extended mechanical life largely.
In this embodiment, the control of stirring motor 111 rotating speeds can realize in several ways.
For example, the input voltage that can supply with stirring motor 111 by change is adjusted the speed of this stirring motor 111.
And for example, the voltage of supplying with stirring motor 111 also can change by Wave-cutting method, further, by cutting wave circuit, input voltage is cut to ripple, and a section ripple dutycycle is 5%-80%.According to one embodiment of present invention, this section of ripple dutycycle can be 10%-50%.Further, according to another preferred embodiment, this section of ripple dutycycle can be 10%-30%.
Thus, by control, cut wave circuit and input voltage is cut to the input voltage that the dutycycle of ripple is the required stirring motor 111 of acquisition, thereby obtain the output speed of required stirring motor 111.
Shown in Fig. 4-Fig. 6, wherein input voltage is UO, by Wave-cutting method, this voltage U 0 is reduced to U2, thereby realizes the control of stirring motor 111 rotating speeds.As shown in Figure 4, this voltage waveform is less than 10% by intercepting, and as shown in Figure 5, this voltage waveform is cut ripple 50%, as shown in Figure 6, can cut ripple by offset of sinusoidal input voltage waveform, the effect reducing to obtain motor input voltage.For another example, the voltage of supply stirring motor 111 changes by a minute platen press.Can be by different voltage U 2, U0 is provided, and by the switching of switch 115, realize the change of the input voltage of stirring motor 111.It should be noted that, the obvious understanding of those of ordinary skill can provide the input voltage more than 2, and by change-over switch 115, realizes the variation of input voltage.
According to some embodiments of the present invention, pulping materials comprises bean or pea and for the liquid of submergence bean or pea, this liquid can be water.Further, the bean or pea of this pulping materials and the ratio of liquid are 1:15~1:5.It should be noted that, these bean or pea can be that dry beans can be also wet beans.
According to some embodiments of the present invention, the method for preparing soya-bean milk is carried out preheating to pulping materials before being also included in pulverising step, and within the temperature of described preheating is less than 50 degree scopes on the temperature of described liquid.Preferably, within the temperature of described preheating is less than 20 degree scopes on the normal temperature of described liquid.Be conducive to like this grinder 103 and smash bean or pea, can improve crush efficiency, can shorten to a certain extent the time of soya-bean milk processed.
According to some embodiments of the present invention, the method for preparing soya-bean milk also comprises: after heating infusion step, the soya-bean milk of infusion is carried out to froth breaking, can improve like this mouthfeel of soya-bean milk.Be understandable that, the principle of froth breaking and method have been prior art, that is to say that the present invention can adopt the mode identical or close with existing froth breaking mode to carry out froth breaking to the ripe soya-bean milk after heating infusion.
Further, after froth breaking step, to user, send alerting signal, this alerting signal can be optical signal, can certainly be acoustical signal, or also can be optoacoustic mixed signal.Reminding user, facilitates user to take soya-bean milk so well.
According to some embodiments of the present invention, grinder 103 is same parts with agitator 109, and pulverizing motor 105 is same parts with stirring motor 111, that is to say, grinder 103 had both had crushing function, also possessed agitating function simultaneously.
Certainly, the invention is not restricted to this, in other embodiments of the invention, agitator 109 and grinder 103 can be also independent parts, now pulverizing motor 105 and stirring motor 111 is also two independent motors, for example, in one of them example of the present invention, this agitator 109 can be arranged on separately the inner bottom part of the staving 101 of soy bean milk making machine, stirring motor 111 can be arranged on the outer bottom of staving 101, and the output shaft of stirring motor 111 can extend in staving 101 and be connected with agitator 109 through the diapire of staving 101.

Agitator 109 is arranged in staving 101, for stirring.Stirring motor 111 is connected with agitator 109, to drive agitator 109 to rotate.
Controller is used for controlling pulverizing motor 105 and drives grinders 103, raw soya-bean milk is pulverized and obtained to a pair of pulping materials being contained in staving 101, and for 107 pairs of raw soya-bean milks of control heater, heat infusion, and control stirring motor 111 driving agitators 109 and in heating infusion process, raw soya-bean milk is stirred.
Wherein raw soya-bean milk is heated in the process of infusion, raw soya-bean milk is stirred, the speed stirring is 1000rpm~3000rpm, inventor surprisingly finds that through test of many times mixing speed can affect the generation that is charred phenomenon, therefore, inventor by further research mixing speed on the impact that whether can produce the degree that is charred and is charred in heating infusion process, the speed not found is higher better to telling on of preventing from being charred, therefore inventor is summed up and is drawn by test of many times: while adopting above-mentioned mixing speed to stir raw soya-bean milk when heating infusion, can effectively avoid the generation that is charred.
Soy bean milk making machine is stirring by 109 pairs of pulping materials of agitator raw soya-bean milk infusion process under predetermined speed according to an embodiment of the invention, can avoid the generation that is sticking phenomenon and overfoaming phenomenon in soya-bean milk process processed.Due to the cause of the Speed Reduction stirring when stirring, the life-span of stirring motor is also extended simultaneously.
According to one embodiment of present invention, the speed of the stirring of agitator 109 can be 1300-2500rpm.Can more effectively prevent from being thus charred and soya-bean milk foam overflow in heating infusion process.
According to some embodiments of the present invention, grinder 103 is same parts with agitator 109, and pulverizing motor 105 is same parts with stirring motor 111, that is to say, grinder 103 had both had crushing function, also possessed agitating function simultaneously.In these some embodiment, grinder 103 is removably fixedly connected with pulverizing motor 105, and the assembling that facilitates like this grinder 103 and pulverize motor 105 also can be convenient for changing grinder 103 simultaneously when grinder 103 damages.
Certainly, the invention is not restricted to this, in other embodiments of the invention, agitator 109 and grinder 103 can be also independent parts, now pulverizing motor 105 and stirring motor 111 is also two independent motors, for example, in one of them example of the present invention, this agitator 109 can be arranged on separately on the inwall of staving 101 of soy bean milk making machine, stirring motor 111 can be arranged on the outer bottom of staving 101, and the output shaft of stirring motor 111 can extend in staving 101 and be connected with agitator 109 through the diapire of staving 101.
According to some embodiments of the present invention, pulping materials comprises bean or pea and for the liquid of submergence bean or pea, this liquid can be water.Further, the bean or pea of this pulping materials and the ratio of liquid are 1:15~1:5.It should be noted that, these bean or pea can be that dry beans can be also wet beans.Thus, soy bean milk making machine of the present invention not only can adopt dry beans, certainly also can adopt bubble beans, has improved like this range of application of soy bean milk making machine.
According to some embodiments of the present invention, the method for preparing soya-bean milk is carried out preheating to pulping materials before being also included in pulverising step, and within the temperature of described preheating is less than 50 degree scopes on the temperature of described liquid.Preferably, within the temperature of described preheating is less than 20 degree scopes on the normal temperature of described liquid.Be conducive to like this grinder 103 and smash bean or pea, can improve crush efficiency, can shorten to a certain extent the time of soya-bean milk processed.
According to some embodiments of the present invention, controller also for after heating infusion step, control heater 107 heats and controls stirring motor 111 simultaneously and drive agitators 109 to carry out froth breaking.Like this, can avoid soya-bean milk foam overflow, pollute staving 101, leaky even occurs, also greatly improve the mouthfeel of soya-bean milk simultaneously.
Be understandable that, the principle of froth breaking and method have been prior art, that is to say that the present invention can adopt the mode identical or close with existing froth breaking mode to carry out froth breaking to the ripe soya-bean milk after heating infusion.
Further, soy bean milk making machine also comprises reminiscences 113, controller be connected with reminiscences 113 for after froth breaking step, control this reminiscences 113 and send alerting signal.Reminding user, facilitates user to take soya-bean milk so well.Wherein, alerting signal is optical signal and/or acoustical signal, that is to say, reminiscences 113 can be optical signal reminiscences 113, or can be voice reminder 113, or optoacoustic reminiscences 113.
For example, reminiscences 113 can be the LED lamp of flicker, and reminiscences 113 can be also player etc. certainly.
According to one embodiment of present invention, controller is controlled pulverizing motor 105 and is driven grinder 103 in mode intermittently, so that raw soya-bean milk is pulverized and obtained to the pulping materials being contained in staving 101.Thus, can reduce grinding time, save electric energy.And, adopt batch (-type) to pulverize and can also avoid pulverizing the motor overheating that motor 105 causes owing to working long hours, and motor is caused damage.
As shown in Figure 1 and Figure 2, according to one embodiment of present invention, controller is controlled and is pulverized motor 105 with 103 rotations of First Speed V1 driving grinder, and First Speed V1 is not more than the rated speed V0 that pulverizes motor 105; And agitator 109 is in heating infusion process, controller is controlled the speed that stirring motor 111 drives 109 pairs of raw soya-bean milks of agitators to stir and is less than described First Speed V1.Be understandable that, speed V1 can be less than or equal to the rated speed V0 of motor, that is to say, in crushing process, the rotating speed of controller control pulverizing motor 105 is no more than the rated speed of himself.Because finding mixing speed, inventor is not the bigger the better, therefore on this basis, inventor has carried out lot of experiments, inventor is surprised to find, and while being no more than V0/2 by mixing speed V2 is controlled at, can improve well the concentration that makes soya-bean milk, the phenomenon that is sticking of pulping process is further improved simultaneously, slurries foam also reduces greatly, can facilitate for example the carrying out of follow-up de-foaming process like this, reduces froth breaking difficulty.
For example, according to one embodiment of present invention, pulverize the rated speed V0=12000 rev/min of motor 105, speed V2≤3000 rev/min, controller is no more than 3000 revs/min by controlling the output speed of stirring motor 111 like this, can obtain the soya-bean milk that protein content is higher, it is very light that the process of infusion is simultaneously sticking degree.
Further, inventor finds, low whipping speed V2≤V0/4, and the soymilk concentration making further improves, and almost does not occur being sticking phenomenon simultaneously, when having improved soya-bean milk nutrition, improves better the generation of even avoiding being sticking phenomenon.It should be noted that, mixing speed V2 also can be chosen to as follows: V0/4≤V2≤V0/2.
For example, according to one embodiment of present invention, pulverize the rated speed V0=12000 rev/min of motor 105, speed V2≤1600 rev/min, controller is no more than 1600 revs/min by controlling the output speed of stirring motor 111 like this, can obtain the soya-bean milk that protein content is higher, the process of infusion simultaneously exists hardly and is sticking phenomenon.
In this embodiment, the speed of controller control stirring motor 111 can be at 1200-3000 rev/min.Obtain thus the good effect not being sticking.In addition, because the rotating speed of motor is reduced to the over half of traditional rotating speed, thereby extended mechanical life largely.By mixing speed being controlled in this speed interval, at the pulping materials that uses identical beans water ratio, for example take the soya-bean milk that pulping materials that beans water ratio is 1:15 makes, its concentration is that the content of soya-bean milk solid can be greater than 6.0g/100mL, and this content also exceeds about 36% than the standard 4.4g/100mL at the highest level of present soy bean milk making machine GB GB-T26167-2010 defined.
