Below by being elaborated according to the method and apparatus for the preparation of soya-bean milk of the present utility model.
Method for the preparation of soya-bean milk of the present utility model 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 utility model is not limited 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 utility model 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.
Utility model people 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, utility model people 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, utility model people has proceeded great many of experiments and research discovery, cancel heating process in advance, 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 the generation that is sticking phenomenon and even avoids being sticking phenomenon simultaneously.
3 pairs of preparation method of soymilk of the present utility model are described in detail below with reference to accompanying drawings.According to the method for preparing soya-bean milk of an embodiment of the utility model, comprise 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 of the interior direct pulverizing acquisition of staving 101 not process heats and is pulverized, and compared with heating the pulping materials of rear pulverizing or limit heating edge pulverizing acquisition, in the case of identical beans liquor ratio, has higher soymilk concentration.Then, the raw soya-bean milk being contained in staving 101 is heated to infusion (S2).
Wherein, raw soya-bean milk is heated in the process of infusion, raw soya-bean milk is stirred, the speed of stirring becomes negative correlation with the time.In other words,, in heating infusion process, to the mixing speed of raw soya-bean milk As time goes on, mixing speed is more and more slower.
According to the method for preparing soya-bean milk of embodiment of the present utility model, cancel 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, preposition by pulverising step, can obtain like this raw soya-bean milk that concentration is higher, and, become negative correlation in the speed that raw soya-bean milk infusion process is stirred with the time, can avoid the generation that is sticking phenomenon and overfoaming phenomenon in soya-bean milk process processed, simultaneously, because the speed stirring is all the time in lower value, can make the life-span of stirring motor 111 also be extended.
According to an embodiment of the present utility model, the speed of stirring can be less than 3000 revs/min.Utility model people surprisingly finds that through test of many times mixing speed can affect the generation that is charred phenomenon, therefore, utility model people 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 utility model people is summed up and is drawn by test of many times: in the time that heating adopts the low mixing speed that is less than 3000 revs/min when infusion, be effectively to avoid the generation that is charred.
According to an embodiment of the present utility model, mixing speed is less than 1000 revs/min in the given time.Can carry out stirring more at a slow speed to soya-bean milk thus, make more abundant by infusion of raw soya-bean milk, promote the mouthfeel of soya-bean milk.According to an embodiment of the present utility model, can at least occupy 70% of whole mixing time with 1000-3000 rev/min of time of stirring.Thus, can avoid soya-bean milk being charred in infusion as far as possible.
For example can drive grinder 103 to rotate with First Speed V1 by setting controller control pulverizing motor 105, First Speed V1 be not more than the rated speed V0 that pulverizes motor; And agitator 109 is in heating infusion process, the speed V2 that controller control stirring motor 109 drives agitator 105 to stir raw soya-bean milk is less than First Speed V1.
Because finding mixing speed, utility model people is not the bigger the better, therefore on this basis, utility model people has carried out lot of experiments, for example in whipping process, As time goes on mixing speed V2 is set as successively: 3000 revs/min revs/min, 2600 revs/min revs/min, 2000 revs/min revs/min, 1500 revs/min revs/min, 900 revs/min revs/min, 500 revs/min revs/min until infusion finish, utility model people is surprised to find, being sticking phenomenon is further improved, slurries foam also reduces greatly, can facilitate so for example the carrying out of follow-up de-foaming process, reduce 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 the output speed of controlling stirring motor 111, and it is very light that infusion process is sticking degree.
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.

According to embodiment more of the present utility model, controller also for after heating infusion step, control heater 107 heats and controls stirring motor 111 simultaneously and drive agitator 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 utility model 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 so well, facilitates user to take soya-bean milk.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 an embodiment of the present utility model, controller control is pulverized 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 an embodiment of the present utility model, controller control is pulverized motor 105 and is driven grinder 103 to rotate with First Speed V1, and First Speed V1 is not more than the rated speed V0 that pulverizes motor 105; And agitator 109 is in heating infusion process, the speed that controller control stirring motor 111 drives agitator 109 to stir raw soya-bean milk 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, utility model people is not the bigger the better, therefore on this basis, utility model people has carried out lot of experiments, utility model people is surprised to find, and while being no more than V0/2, can improve well the concentration that makes soya-bean milk by mixing speed V2 is controlled at, the phenomenon that is sticking of pulping process is further improved simultaneously, slurries foam also reduces greatly, can facilitate so for example the carrying out of follow-up de-foaming process, reduces froth breaking difficulty.
For example, according in an embodiment of the present utility model, pulverize the rated speed V0=8000 rev/min of motor 105, speed V2≤3000 rev/min, controller is no more than 3000 revs/min by the output speed of controlling 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, utility model people finds, low whipping speed V2≤V0/4, and the soymilk concentration making further improves, and almost does not occur being sticking phenomenon simultaneously, in 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 an embodiment of the present utility model, pulverize the rated speed V0=8000 rev/min of motor 105, speed V2≤1600 rev/min, controller is no more than 1600 revs/min by the output speed of controlling 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 less than 3000 revs/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 soya-bean milk that uses the pulping materials of identical beans water ratio for example to make as the pulping materials of 1:11 taking beans water ratio, 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.
