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 heat infusion, in the process of infusion by output speed and other factors such as controlling stirring motor as the distance of the temperature of raw soya-bean milk, agitator and staving diapire etc. meets under the condition of certain relation, not only can obtain higher concentration of slurry, the while can also effectively be improved the generation that is sticking phenomenon and even avoids being sticking phenomenon.

1-Fig. 5 is described in detail preparation method of soymilk of the present invention below with reference to accompanying drawings.The method of preparing soya-bean milk according to some embodiments of the invention, comprises the following steps:

The pulverizing motor 105 of controlling soy bean milk making machine drives the grinder 103 of soy bean milk making machine directly to pulverize pulping materials, to obtain raw soya-bean milk (S1).

The raw soya-bean milk being contained in the staving 101 of soy bean milk making machine is heated to infusion (S2).

Wherein, raw soya-bean milk being heated in the process of infusion, by the agitator 109 being arranged in the staving 101 of soy bean milk making machine, this raw soya-bean milk is stirred, and raw soya-bean milk is stirred at least one meeting in following three kinds of relations, wherein V2 is the rotating speed for driving the stirring motor 111 that agitator 109 stirs.

The first: 10 turn/(point * mm)≤V2/h≤2000 turn/(point * mm), and wherein h is the distance (S21) of the lower surface of agitator 109 and the diapire of staving 101.

Here, need explanation a bit, " lower surface of agitator 109 " should make broad understanding, for example agitator 109 can be configured to a blade, now above-mentioned " lower surface of agitator 109 " can be understood as the lower surface of this blade, i.e. the lower surface of its rotational trajectory when this blade rotation.

Certainly, multiple blades that agitator 109 also can be configured to roughly radially distribute, the lower surface of the plurality of blade is preferably in same plane, now above-mentioned " lower surface of agitator 109 " can be understood as in the common residing plane of lower surface of the plurality of blade, i.e. the lower surface of its rotational trajectory when the plurality of blade rotation.

Certainly, the lower surface of the plurality of blade also can be in different planes, now above-mentioned " lower surface of agitator 109 " can be understood as: the lower surface of the blade that in multiple blades, level height is minimum, that is to say, the lower surface of one of them blade in the plurality of blade is lower than the lower surface of all the other blades, and what the lower surface of this blade referred to is exactly above-mentioned " lower surface of agitator 109 ".

The second: 12.5 turn/(point * mm)≤V2/d1≤5000 turn/(point * mm), wherein d1 is the radial distance (S22) of the internal face of the outermost of agitator 109 rotary motion trace and the perisporium of staving 101, in other words, this d1 refers to the radial distance of the inner peripheral surface of outermost end diametrically of agitator 109 and staving 101, as shown in Figure 1.

The third: 16 turn/(point * DEG C)≤V2/K≤2000 turn/(point * DEG C), the temperature (S23) that wherein K is raw soya-bean milk.

Preparation method of the present invention, cancel the heating steps in traditional preparation technology, directly the raw soya-bean milk in soymilk machine barrel body 101 is heated to infusion, preposition by pulverising step, comparing so traditional preparation technology can save the heat time, effectively shorten mixing time, simultaneously by follow the slow stirring of agitator 109 in to raw soya-bean milk infusion process, by controlling the output speed V2 of stirring motor 111, make this V2 meet at least one in above-mentioned relation formula, that is to say, V2 can only meet a kind of relation above, or meet the combination of above-mentioned any number of relation, all to improve largely the soymilk concentration of making, can also improve simultaneously and be sticking phenomenon and overfoaming phenomenon in soya-bean milk process processed.Due to the cause of the Speed Reduction stirring, the life-span of stirring motor is also extended simultaneously.

Below with reference to Fig. 3-Fig. 5, above-mentioned relation is described in detail respectively.But it should be noted that; following explanation is the object of example; instead of in order to limit the scope of the invention; those of ordinary skill is after having read following technical proposals of the present invention; obviously can technical scheme or part technical characterictic wherein be combined or be replaced, revise, within this also falls into protection domain of the presently claimed invention.

embodiment mono-

Fig. 3 has shown the process chart corresponding with this embodiment.In this embodiment, pulverising step can be intermittently to pulverize, the pulverizing motor 105 that is soy bean milk making machine is controlled so as to batch (-type) rotation, adopt mode off and on to pulverize, can improve and pulverize mechanical life of motor 105, avoid pulverizing the damage causing that runs up of motor 105 long-time continuous.

For example, the broken motor 105 of the controlled powder process of controller can speed V1 rotates N cycle T, and between adjacent two cycle T, pulverize motor 105 stop being scheduled between M, Qi Zhongyou: 1≤N≤50,5 seconds≤T≤40 second, 10 seconds≤M≤20 second.

For example, with N=10, T=20 second, M=15 second is example, and controller control is pulverized motor 105 and rotated 10 cycles with speed V1 so, and each cycle is 20 seconds, and between adjacent two cycles, pulverizes motor 105 and shut down 15 seconds.Be appreciated that this sentences N=10, T=20 second, M=15 second is only schematically to illustrate, can not be interpreted as a kind of restriction of the present invention.

Because finding mixing speed, inventor is not the bigger the better, therefore on this basis, inventor has carried out lot of experiments, and inventor is surprised to find, mixing speed V2 and, the distance h of the lower surface of agitator 109 and the diapire of staving 101 also can change the degree being sticking in infusion process.Inventor obtains by great many of experiments: in heating infusion process, the distance h of the diapire of the lower surface of mixing speed V2 and agitator 109 and staving 101 meets following relation: 20 turn/(point * mm)≤V2/h≤1000 turn/(point * mm), can improve well the concentration that makes soya-bean milk, the phenomenon that is sticking of pulping process is further improved simultaneously, in infusion process, foam also reduces greatly simultaneously, thereby can facilitate the carrying out of follow-up de-foaming process.

Further, inventor finds, in heating infusion process, the distance h of the diapire of the lower surface of mixing speed V2 and agitator 109 and staving 101 further meets following relation: 20 turn/(point * mm)≤V2/h≤400 turn/(point * mm), the soymilk concentration making further improves, almost there is not being sticking phenomenon, in having improved soya-bean milk nutrition, improve better the generation of even avoiding being sticking phenomenon simultaneously.

In this embodiment, the speed of stirring motor 111 can be 1300-2500 rev/min.Can 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.

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, obtain the input voltage of required stirring motor 111 thereby cut by control the dutycycle that wave circuit cuts ripple to input voltage, thereby obtain the output speed of required stirring motor 111.
