The pulverizing motor 105 of controlling soy bean milk making machine drives 103 pairs of pulping materials of grinder of soy bean milk making machine directly to pulverize, 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.

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

Below with reference to Fig. 3-Fig. 8, above-mentioned relation is described in detail respectively.But it should be noted that; following explanation is the object of example; rather than in order to limit protection domain of the present utility model; those of ordinary skill is after having read following technical proposals of the present utility model; obviously can technical scheme or part technical characterictic wherein be combined or be replaced, revise, within this also falls into the desired protection domain of the utility model.

embodiment mono-

Fig. 3 has shown the process chart corresponding with this embodiment.In this embodiment, speed V1 is less than or equal to the rated speed V0 of motor, that is to say, in crushing process, the rotating speed of pulverizing motor 105 is no more than the rated speed of himself.In this embodiment, pulverising step can be intermittently to pulverize, and the pulverizing motor 105 of soy bean milk making machine is controlled so as to batch (-type) rotation.

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, wherein have: 1≤N≤50,5 seconds≤T≤40 second, 1 second≤M≤60 second.

For example, with N=10, T=20 second, M=15 second is example, and controller is controlled and pulverized motor 105 and rotate 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 utility model.

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, in heating infusion process, 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, and slurries foam also reduces greatly, can facilitate for example the carrying out of follow-up de-foaming process like this, reduce froth breaking difficulty.

For example, in this embodiment, pulverize the rated speed V0=8000 rev/min of motor 105, speed V2≤3000 rev/min, by controlling the output speed of stirring motor 111, be no more than 3000 revs/min, 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, in heating infusion process, low whipping speed V2≤V0/4, the soymilk concentration making further improves, and almost does not occur being sticking phenomenon simultaneously, when having improved soya-bean milk nutrition, improve better the generation of even avoiding being sticking phenomenon.It should be noted that, in heating infusion process, mixing speed V2 also can be chosen to as follows: V0/4≤V2≤V0/2.

For example, in this embodiment, pulverize the rated speed V0=8000 rev/min of motor 105, speed V2 can be chosen to: V2≤1600 rev/min, by controlling the output speed of stirring motor 111, be no more than 1600 revs/min, 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 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 an embodiment of the present utility model, this section of ripple dutycycle can be 10%-50%.Further, according to another one embodiment of the present utility model, 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. 9-Figure 11, 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 9, this voltage waveform is less than 10% by intercepting, and as shown in Figure 10, this voltage waveform is cut ripple 50%, as shown in Figure 11, 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.As shown in Figure 12, 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.
