The scheme provides an aseptic micro-channel mixing system which can be used for conveniently mixing at least two feed liquids in an aseptic environment and can be widely applied to beverage machines. Different from the mixing system in the prior art, the aseptic micro-channel mixing system is widely applied to practical application by respectively sterilizing, heating and pushing micro-channels by means of steam in different using states in a mode of introducing steam into a pipeline, and the mixing system does not need to be additionally provided with a mixing container, so that the feed liquid can be mixed in the aseptic micro-channel.
Specifically, this scheme provides a sterile microchannel system of mixing, includes: the device comprises a conveying pipeline 10, a steam generator 30, a feed liquid conveying interface 50 and a liquid inlet 11, wherein the steam generator 30 is connected with the conveying pipeline 10 through a steam dispersion valve 40, the feed liquid conveying interface 50 is connected with the conveying pipeline 10 through a feed liquid valve 60, the liquid inlet 11 of the conveying pipeline 10 is provided with a liquid inlet valve 20, and an on-off valve 31 is arranged between the steam generator 30 and the steam dispersion valve 40.

Specifically, the steam in the steam distribution valve 40 is delivered in a unidirectional manner from the on-off valve 31 to the delivery pipe 10. That is, the steam generated from the steam generator 30 may be introduced into the transfer pipe 10 in a single direction through the steam distribution valve 40. And it is particularly worth mentioning that the vapor dispersion valve 40 is preferably provided close to the liquid inlet 11. The steam plays different roles in the sterile micro-channel mixing system according to different opening states of the liquid inlet valve 20, the on-off valve 31 and the liquid inlet valve 60, and the different roles of the steam in the scheme are described as follows:
if the liquid inlet valve 20 and the liquid inlet valve 60 are both closed and no liquid is present in the conveying pipeline 10, steam enters the conveying pipeline 10 through the steam dispersion port 41 to sterilize the conveying pipeline 10 at a high temperature, wherein the temperature of the steam is higher than 100 ℃.
If the liquid inlet valve 20 and the liquid feed valve 60 are both closed and liquid exists in the conveying pipeline 10, steam enters the conveying pipeline 10 through the steam dispersion port 41 to convey the liquid in the conveying pipeline 10, and upward power of the steam pushes the liquid in the conveying pipeline 10 to push the material.
The feed liquid conveying interface 50 inputs feed liquid, the feed liquid sprays steam into the conveying pipeline in at least one of a reduced inner diameter point-shooting state and gap scattering, and the feed liquid valve sprays second feed liquid into the conveying pipeline in at least one of a reduced inner diameter point-shooting state and gap scattering.
Specifically, the reduced inner diameter spot shot state refers to: the feed liquid with a certain pressure is input into the feed liquid through the feed liquid conveying interface 50, and the feed liquid valve 60 is provided with a small hole smaller than the inner diameter of the conveying pipeline 10 at the position of the inner wall of the conveying pipeline 10, so that the feed liquid is pressurized and accelerated at the small hole and is sprayed into the inner diameter of the conveying pipeline 10 to be collided and mixed with other liquid flowing in the inner diameter of the conveying pipeline 10 at a high speed.
The gap scattering means: when provided as a slit, the slit may be provided as at least one elongated slit having an opening cross-sectional area smaller than the inner diameter of the delivery pipe 10, or a circular slit, also provided against the inner wall of the delivery pipe 10.
That is to say, in this scheme, steam not only plays the effect of disinfection in this scheme but also can play the effect of pushing away the material simultaneously, can also play the effect that the liquid that the feed liquid flows in the pipeline and the pipeline carries out instant system of mixing. Meanwhile, the dual functions of the steam are matched with the using mode of the sterile micro-channel mixing system, so that the sterile micro-channel mixing system is in different states, and the specific scheme content is as follows:
before the conveying pipeline 10 is fed with liquid and/or feed materials, namely, before the liquid and the feed materials are fed with liquid, the liquid inlet valve 20 and the material liquid valve 60 are closed, the on-off valve 31 is opened, and steam generated by the steam generator 30 enters the conveying pipeline 10, and at the moment, the aseptic micro-channel mixing system is in a steam cleaning and/or sterilizing state. Wherein the steam clean state of the aseptic micro-channel mixing system refers to: the impurities possibly remaining in the conveying line 10 or the liquid retained by the conveying line are conveyed towards the liquid outlet 12 by steam; the sterilization status of the sterile microchannel mixing system refers to: the inner wall of the transfer line 10 is sterilized by the high temperature of the steam.
Then, the liquid inlet valve 20 is opened and the on-off valve 20 is kept opened, when the liquid inlet valve 20 is a one-way valve, the one-way valve is designed to be arranged in a one-way mode in the direction of the liquid outlet 12, then, when the liquid inlet 11 enters liquid, the liquid inlet valve 20 is automatically opened under the pressure of the liquid, correspondingly, the first liquid material enters the conveying pipeline 10 from the liquid inlet 11, steam enters the conveying pipeline 10 through the steam dispersion valve 40, at the moment, the liquid exists in the conveying pipeline 10, and the steam can heat the liquid in the conveying pipeline 10, so that the liquid in the conveying pipeline 10 is in a steam heating state.
Keeping the liquid inlet valve 20 open, opening the liquid inlet valve 60, at this time, the first liquid enters the conveying pipeline 10 from the liquid inlet 11, the second liquid enters the conveying pipeline 10 from the liquid conveying interface 50, the first liquid/the first liquid sprays steam into the conveying pipeline 10 in at least one of the modes of reducing the inner diameter spot-shooting state and gap scattering, the liquid inlet valve 60 sprays the second liquid into the conveying pipeline 10 in at least one of the modes of reducing the inner diameter spot-shooting state and gap scattering, the on-off valve 31 is closed, the first liquid and the second liquid are mixed in the sterile conveying pipeline 10, and at this time, the sterile microchannel mixing system is in a liquid mixing state.
And then, the liquid inlet valve 20 is closed, the liquid inlet 11 is stopped from conveying the first liquid into the conveying pipeline 10, the on-off valve 31 is opened, and the aseptic micro-channel mixing system is changed from a liquid mixing state to a steam material pushing state.
The feed liquid valve 60 is closed again, the second feed liquid is stopped from being conveyed into the conveying pipeline 10, the steam is continuously conveyed until no liquid exists in the conveying pipeline 10 and/or the sterilization poison is reached, and then the on-off valve 31 is closed.
In addition, in other embodiments, when mixed liquid is in the delivery pipe 10, the on-off valve 31 is opened after the liquid inlet valve 20 and the liquid valve 60 are closed, so that the mixed liquid in the delivery pipe 10 can be pushed by the steam. That is, in some cases, the on-off valve 31 is opened after the liquid inlet valve 20 is closed, and in other cases, the on-off valve 31 is opened after both the liquid inlet valve 20 and the feed liquid valve 60 are closed.
In the embodiment of the present disclosure, the liquid inlet valve 20 unidirectionally conveys the liquid entering the conveying pipeline 10 from the liquid inlet 11, the liquid valve 60 unidirectionally conveys the liquid entering the conveying pipeline 10 from the liquid conveying port 50, the liquid valve 60 is disposed between the liquid inlet valve 20 and the liquid outlet 12, and the vapor dispersing valve 40 is disposed between the liquid inlet valve 20 and the liquid valve 60.

When the mode of electric opening is selected, the liquid inlet valve 20, the on-off valve 31 and the liquid feed valve 60 are in communication connection with the control end.
It is worth mentioning that in the embodiment of the present embodiment, the steam dispersion valve 40 sprays the steam generated by the steam generator 30 in a dispersed state, and/or the feed liquid valve 60 sprays the second feed liquid in a dispersed state. Specifically, the steam dispersion valve 40 sprays steam into the conveying pipeline 10 in at least one of a reduced inner diameter spot-shooting state and a gap scattering state, and/or the feed liquid valve 60 sprays the second feed liquid into the conveying pipeline 10 in at least one of a reduced inner diameter spot-shooting state and a gap scattering state.

In addition, in order to further ensure that all the steam can enter the conveying pipeline 10 and can be sufficiently mixed with the liquid during heating, the steam dispersion port 41 of the steam dispersion valve 40 is arranged against the inner wall of the conveying pipeline 10, and when no steam passes through the steam dispersion port 41, the steam dispersion port 41 is not communicated with the conveying pipeline 10.

In one embodiment of the present disclosure, the saddle 4221 is disposed at the bottom end of the inner wall of the air inlet passage 422.
In addition, in the present embodiment, the state change of the valve body 43 changes as the vapor pressure via the intake pipe 422 changes. Specifically, when high-pressure steam enters the air inlet pipe 422, the high-pressure steam applies pressure to the valve element 43, and when the pressure is greater than the elastic force of the elastic element 432, the high-pressure steam presses the valve element 43 to drive the valve element 43 to move towards the conveying pipeline 10, and during the descending process of the valve element 43, the upward elastic force of the elastic element 432 is increased until the upward elastic force and the downward high-pressure steam pressure are cancelled out, and the valve element 43 stops moving. When the pressure of the high-pressure steam is released, that is, when the high-pressure steam pressure is no longer applied to the spool 43, the elastic member 432 has a restoring force to restore the natural state, and the elastic member 432 applies an elastic force to the spool core 431 to urge the spool 43 to restore the closed state.
In a second aspect, the present disclosure provides an aseptic micro-channel mixing method cooperating with the aseptic micro-channel mixing system described above, including the following steps: before the conveying pipeline 10 is fed with liquid and/or feed, the on-off valve 31 is opened, steam generated by the steam generator 30 enters the conveying pipeline 10, and the sterile micro-channel mixing system is in a steam cleaning state and/or achieves the effect of killing bacteria and toxins; then the first feed liquid enters the conveying pipeline 10, or the second feed liquid enters the conveying pipeline 10 at any time before, during or after the first feed liquid enters the conveying pipeline 10, the on-off valve 31 is closed, and the sterile micro-channel mixing system is in a liquid mixing state; then stopping conveying the first feed liquid and/or the second feed liquid into the conveying pipeline 10, enabling the conveying pipeline 10 to have no new feed liquid input, starting the on-off valve 31, changing the aseptic micro-channel mixing system from a liquid mixing state to a steam pushing state, prolonging the time for starting the on-off valve 31 after pushing is finished, or starting the on-off valve 31 again after interruption, and changing the steam pushing state to a steam cleaning state and/or achieving the effect of killing bacteria and viruses; the on-off valve 31 is then closed, and the process ends.
The explanation of the structure of the aseptic microchannel mixing method involved in the aseptic microchannel mixing method is given above, and redundant explanation is not given here.
The present invention is not limited to the above-mentioned preferred embodiments, and any other products in various forms can be obtained by anyone in the light of the present invention, but any changes in the shape or structure thereof, which have the same or similar technical solutions as those of the present application, fall within the protection scope of the present invention.
