Referring 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; 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 combine or replace, revise technical scheme wherein or portion of techniques feature, this also falls within protection domain of the presently claimed invention.

embodiment one

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

Such as, the broken motor of the controlled powder process of controller 105 can rotate N number of cycle T by speed V1, and pulverize between adjacent two cycle T motor 105 stop predetermined between M, Qi Zhongyou: 1≤N≤50,5 seconds≤T≤40 second, 1 second≤M≤60 second.

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

Because inventor finds that mixing speed is not the bigger the better, therefore on this basis, inventors performed lot of experiments, inventor is surprised to find, in heating infusion process, by mixing speed V2 is controlled when being no more than V0/2, can improve the concentration of obtained soya-bean milk well, the phenomenon that is sticking of pulping process is further improved simultaneously, and slurries foam also reduces greatly, the carrying out of such as follow-up de-foaming process can be facilitated like this, reduce froth breaking difficulty.

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

Such as, in this embodiment, pulverize the rated speed V0=8000 rev/min of motor 105, speed V2 can be chosen to: V2≤1600 rev/min, 1600 revs/min are no more than by the output speed controlling stirring motor 111, can obtain the soya-bean milk that protein content is higher, simultaneously infusion process exists hardly and is sticking phenomenon.

In this embodiment, the speed of stirring motor 111 can control at 1300-2500 rev/min.Obtain the good effect be not sticking thus.In addition, the rotating speed due to motor is reduced to the over half of traditional rotating speed, thus mechanical life is extended largely.

In this embodiment, the control of stirring motor 111 rotating speed can realize in several ways.

Such as, can be adjusted by the speed of input voltage to this stirring motor 111 changing supply stirring motor 111.

And for example, the voltage of supply stirring motor 111 also changes by Wave-cutting method, further, carry out cutting ripple, and a section ripple dutycycle is 5%-80% by cutting wave circuit to input voltage.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 controlling to cut wave circuit to cut ripple dutycycle to the input voltage input voltage for the stirring motor 111 needed for obtaining, thus the output speed of stirring motor 111 needed for obtaining.

Shown in Fig. 9-Figure 11, wherein input voltage is UO, by Wave-cutting method, this voltage U 0 is reduced to U2, thus realizes the control of stirring motor 111 rotating speed.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 carry out cutting ripple by offset of sinusoidal input voltage waveform, to obtain the effect that motor input voltage reduces.For another example, the voltage supplying stirring motor 111 is changed by point platen press.As shown in Figure 12, by providing different voltage U 2, U0, and the change of the input voltage of stirring motor 111 can be realized by the switching of switch 115.It should be noted that, those of ordinary skill obviously understands the input voltage that can provide more than 2, and realizes the change of input voltage by change-over switch 115.

According to another embodiment of the invention, as shown in figure 13, at least one dividing potential drop branch road 112 is set on the basis of the voltage input circuit of routine.This dividing potential drop branch road 112 is provided with divider resistance 114, and switch 115 is for controlling the input voltage of stirring motor 111.It should be noted that, those of ordinary skill is obviously understood can at normal stirring motor for dividing potential drop branch road hydraulic circuit arranged more than 2, this dividing potential drop branch road is respectively arranged with different divider resistances, and realizes the switching input of input voltage by change-over switch 115.

In brief, wanting the output speed changing stirring motor 111, can realize by changing the equivalent voltage inputing to stirring motor 111, illustrate for Wave-cutting method, point platen press etc. above and can not be interpreted as one restriction of the present invention.Be understandable that, the method for the input voltage of stirring motor 111 can be changed for other, all fall within protection scope of the present invention.
