A kind of fruit vinegar filtering system
Technical field
The present invention relates to a kind of filtering system, particularly a kind of fruit vinegar filtering system.
Background technology
In fruit vinegar Conventional process, tradition clarification, filter type is: Plate Filtration, diatomite filtration, freezing, natural subsidence, centrifugal, the excellent filtration of titanium, filter element filtering etc.But these filter, clarification mode also exists some shortcomings part, these filter, clarification mode complex process, hand labor intensity are large, processing time period is long, and blocking is very fast, and filter material needs frequent replacing, use cost is high, energy consumption is high, and filter effect can only play temporary transient clarification, and pore size filter is uneven, processing mode is unstable, easily there is secondary sedimentation and return muddy in product, transparence is bad, had a strong impact on mouthfeel and the exterior quality of product.
On the other hand, traditional fruit vinegar clarification, filtration process can not be cleaned filtration unit online, and filter type belongs to dead-end filtration, and fruit vinegar clarification, filtration process process operation are got up very inconvenient.
Summary of the invention
The present invention is directed to above-mentioned deficiency, disclose a kind of fruit vinegar filtering system, it is characterized in that, comprising:
Fruit vinegar charging-tank, it is for holding unfiltered fruit vinegar;
First pipeline, it is communicated with described fruit vinegar charging-tank, and described first pipeline is provided with magnetic valve;
Tetrafluoroethylene membrane filtration device, it comprises tetrafluoroethylene, and is connected with described first pipeline;
First pressure pump, itself and described first pipeline connection, be pumped out to described tetrafluoroethylene membrane unit by the fruit vinegar in described first pipeline and filter;
First hay tank, it is set to hold the fruit vinegar after described tetrafluoroethylene membrane filtration device is filtered;
Second pipeline, it is communicated with described first hay tank, and described second pipeline is provided with magnetic valve;
Nano thin-film filtration unit, it comprises nano thin-film, and is connected with described second pipeline;
Second pressure pump, itself and described second pipeline connection, be pumped out to described nano thin-film filtration unit by the fruit vinegar in described second pipeline and filter;
Second hay tank, it is set to hold the fruit vinegar after described nano thin-film device filters;
3rd pipeline, it is communicated with described second hay tank, and described 3rd pipeline is provided with magnetic valve;
Reverse osmosis film filtration unit, it comprises reverse osmosis film, and is connected with described 3rd pipeline;
3rd pressure pump, itself and described 3rd pipeline connection, be pumped out to described reverse osmosis film filtration unit by the fruit vinegar in described 3rd pipeline and filter;
3rd hay tank, it is set to hold the fruit vinegar after described reverse osmosis film filtration devices;
Washing unit, it is connected with described tetrafluoroethylene membrane filtration device, nano thin-film filtration unit and reverse osmosis film filtration unit;
Controller, it is electrically connected with the magnetic valve on described each pipeline, each pressure pump and washing unit.
Preferred version: described washing unit comprises water tank and scavenging pump.
Preferred version: the aperture of tetrafluoroethylene film is between 0.01 μm to 15 μm.
Preferred version: the pore fill-in ratio of nano thin-film is 60 ~ 95%.
Preferred version: reverse osmosis film thickness is between 1 μm to 1000 μm.
Filtering system provided by the invention once can remove high molecular weight protein, colloid, fiber, microorganism etc. in fruit vinegar, avoid the secondary sedimentation occurred under the impacts such as time, temperature, illumination, once filter and can reach technical requirements, shorten the production cycle, filtering system can regularly be cleaned under the control of the controller automatically, regeneration recovers convenient, long service life.

Embodiment
Below in conjunction with embodiment, the present invention is described in further detail:
The invention discloses a kind of fruit vinegar filtering system, it is characterized in that, comprising:
Fruit vinegar charging-tank 1, it is for holding unfiltered fruit vinegar;
First pipeline, it is communicated with described fruit vinegar charging-tank 1, and described first pipeline is provided with magnetic valve;
Tetrafluoroethylene membrane filtration device 5, it comprises tetrafluoroethylene, and is connected with described first pipeline, and the aperture of tetrafluoroethylene film is between 0.01 μm to 15 μm;
First pressure pump 8, itself and described first pipeline connection, be pumped out to described tetrafluoroethylene membrane unit 5 by the fruit vinegar in described first pipeline and filter;
First hay tank 2, it is set to hold the fruit vinegar after described tetrafluoroethylene membrane filtration device 5 is filtered;
Second pipeline, it is communicated with 2 with described first hay tank, and described second pipeline is provided with magnetic valve;
Nano thin-film filtration unit 6, it comprises nano thin-film, and is connected with described second pipeline, and the pore fill-in ratio of nano thin-film is 60 ~ 95%;
Second pressure pump 9, itself and described second pipeline connection, be pumped out to described nano thin-film filtration unit 6 by the fruit vinegar in described second pipeline and filter;
Second hay tank 3, it is set to hold the fruit vinegar after described nano thin-film device 6 filters;
3rd pipeline, it is communicated with described second hay tank 3, and described 3rd pipeline is provided with magnetic valve;
Reverse osmosis film filtration unit 7, it comprises reverse osmosis film, and is connected with described 3rd pipeline, and reverse osmosis film thickness is between 1 μm to 1000 μm;
3rd pressure pump 10, itself and described 3rd pipeline connection, be pumped out to described reverse osmosis film filtration unit 7 by the fruit vinegar in described 3rd pipeline and filter;
3rd hay tank 4, it is set to hold the fruit vinegar after described reverse osmosis film filtration unit 7 filters;
Washing unit 11, it is connected with described tetrafluoroethylene membrane filtration device 5, nano thin-film filtration unit 6 and reverse osmosis film filtration unit 7, and washing unit comprises water tank and scavenging pump.
Controller, it is electrically connected with the magnetic valve on described each pipeline, each pressure pump and washing unit 11.
When fruit vinegar filters, first the valve on the first pipeline opened by controller, fruit vinegar is filtered to tetrafluoroethylene membrane filtration device 5 by the first Pipeline transport by the first pressure pump 8, fruit vinegar after tetrafluoroethylene membrane filtration device 5 is filtered is transported to the first hay tank 2, then the valve on the second pipeline opened by controller, fruit vinegar is filtered to nano thin-film filtration unit 6 by the second Pipeline transport by the second pressure pump 9, fruit vinegar after nano thin-film filtration unit 6 filters is transported to the second hay tank 3, the valve on the 3rd pipeline opened by last controller, fruit vinegar is filtered to reverse osmosis film filtration unit 7 by the 3rd Pipeline transport by the 3rd pressure pump 10, fruit vinegar after reverse osmosis film filtration unit 7 filters is transported to the 3rd hay tank 4, after filtration for some time, controller cuts out the valve on each pipeline, flow into after corresponding each hay tank until the fruit vinegar in each pipeline, washing unit 11 opened by controller, washing unit cleans each membrane filtration device.
